board of a game table is calculated on the basis of identification
information stored in a radio tag, the number of gaming chips is
calculated on the basis of identification information assigned to a
side surface, and the calculated numbers of gaming chips are
compared. Accordingly, it is possible to detect an unauthorized
gaming chip when the unauthorized gaming chip is used in the game
table.
[0068] However, since the system disclosed in JP 2009-66172 A
detects a fraud by calculating the number of bet gaming chips
(placed on the betting board), the system is unable to inspect a
plurality of gaming chips contained in the case in a state where
the gaming chips are contained in the case and detect the
unauthorized gaming chip.
[0069] In this regard, it is an object of the first embodiment to
provide an inspection system and an inspecting device which are
capable of inspecting a plurality of gaming chips contained in a
case in a state where the gaming chips are contained in the
case.
[0070] An inspection system according to a first aspect of the
first embodiment is an inspection system that inspects a gaming
chip having at least first gaming chip information and second
gaming chip information, the second gaming chip information is
arranged on a side surface of the gaming chip in an optically
readable form, the inspection system includes a case that contains
a plurality of gaming chips in a stacked manner and an inspecting
device that inspects the gaming chip contained in the case, wherein
the inspecting device includes a first reading device that acquires
the first gaming chip information of the gaming chip contained in
the case, a second reading device that optically reads the side
surface of the gaming chip contained in the case and acquires the
second gaming chip information, and a determining unit that
determines whether a plurality of gaming chips contained in the
case are pass or fail by determining the authenticity or damages of
all the gaming chips contained the case or the number of gaming
chips for each value using the first gaming chip information
acquired by the first reading device and the second gaming chip
information acquired by the second reading device.
[0071] With this configuration, since both the first reading unit
and the second reading unit acquire the first gaming chip
information and the second gaming chip information from the gaming
chip contained in the case, it is possible to inspect the gaming
chips contained in the case. Further, since two pieces of
information, that is, the first gaming chip information and the
second gaming chip information are acquired from the gaming chip,
and the inspection is performed, the pass/fail determination can be
reliably performed.
[0072] In an inspection system according to a second aspect of the
first embodiment, in the inspection system of the first aspect, the
first gaming chip information and the second gaming chip
information in a common gaming chip include common information, and
the determining unit determines that a plurality of gaming chips
contained in the case are fail when common information portions of
a plurality of pieces of first gaming chip information acquired by
the first reading device do not coincide with common information
portions of a plurality of pieces of second gaming chip information
acquired by the second reading device.
[0073] With this configuration, when an unauthorized gaming chip in
which the common information portion of the first gaming chip
information does not coincide with the common information portion
of the second gaming chip information is contained in the case, the
determining unit can determine that the gaming chips contained in
the case are fail.
[0074] For example, when common identification information is
recorded in the radio tag and the side surface, fail is determined
if a plurality of pieces of identification information read out
from a plurality of radio tags do not coincide completely with a
plurality of pieces of identification information read out from a
plurality of side surfaces. Further, when a value of the gaming
chip is recorded in the radio tag and the side surface, fail is
determined if the number of each value read from the radio tag does
not coincide with the number of each value read from the side
surface.
[0075] In an inspection system according to a third aspect of the
first embodiment, in the inspection system of the first aspect,
both or either of the first gaming chip information and the second
gaming chip information includes individual identification
information individually identifying the gaming chip.
[0076] In an inspection system according to a fourth aspect of the
first embodiment, in the inspection system of the first aspect, the
second gaming chip information includes information indicated by a
designated color indicating the value of the gaming chip and is
information indicating the value of the gaming chip through the
designated color.
[0077] In an inspection system according to a fifth aspect of the
first embodiment, in the inspection system of the third aspect,
both the first gaming chip information and the second gaming chip
information include individual identification information, and a
plurality of gaming chips contained in the case are determined to
be fail when the individual identification information of a
plurality of pieces of first gaming chip information acquired by
the first reading device does not coincide with the individual
identification information of a plurality of pieces of second
gaming chip information acquired by the second reading device.
[0078] With this configuration, when an unauthorized gaming chip in
which the individual identification information of the first gaming
chip information does not coincide with the individual
identification information of the second gaming chip information is
contained in the case, the determining unit determines that the
gaming chips contained in the case are fail.
[0079] In the inspection system of the first aspect, an inspection
system according to a sixth aspect of the first embodiment includes
a storage unit that stores the individual identification
information of at least the first gaming chip information or the
second gaming chip information of a plurality of gaming chips to be
contained in the case, and the determining unit determines that a
plurality of gaming chips contained in the case are fail when the
individual identification information of a plurality of pieces of
first gaming chip information acquired by the first reading device
or a plurality of pieces of second gaming chip information acquired
by the second reading device does not coincide with the individual
identification information of the first gaming chip information or
the second gaming chip information stored in the storage unit.
[0080] With this configuration, when an unauthorized gaming chip in
which the first gaming chip information or the second gaming chip
information is incorrect is contained in a case, the determining
unit can determine that the gaming chips contained in the case are
fail.
[0081] For example, when the individual identification information
indicated by characters is recorded in the radio tag, and the
individual identification information indicated by numbers is
recorded on the side surface, a plurality of pieces of individual
identification information indicated by characters are stored in
the storage unit for the radio tag for each case, a plurality of
pieces of individual identification information indicated by
numbers are stored for the side surface, and fail is determined
when a plurality of pieces of individual identification information
read out from a plurality of radio tags do not coincide with a
plurality of pieces of individual identification information stored
in the storage unit for the radio tag of the case or when a
plurality of pieces of individual identification information read
out from a plurality of side surfaces do not coincide with a
plurality of pieces of individual identification information stored
in the storage unit for the side surface of the case.
[0082] In the inspection system of the first aspect, an inspection
system according to a seventh aspect of the first embodiment
further includes a storage unit that stores a correspondence
relation between the first gaming chip information and the second
gaming chip information, and the determining unit determines that
the plurality of gaming chips contained in the case are fail when a
plurality of pieces of first gaming chip information acquired by
the first reading device and a plurality of pieces of second gaming
chip information acquired by the second reading device do not
coincide with the correspondence relation stored in the storage
unit.
[0083] With this configuration, when a gaming chip in which the
correspondence relation between the first gaming chip information
and the second gaming chip information is inaccurate is contained
in the case, fail can be determined.
[0084] For example, when the identification information is recorded
in the radio tag, and the value is recorded in the side surface,
any value is allocated to each piece of identification information
and stored in the storage unit, the number of each value is
obtained with reference to the storage unit for a plurality of
pieces of identification information read out from the plurality of
radio tags, and fail is determined when the number of each value
read out from the side surface does not coincide with the obtained
number of each value. Conversely, the same applies when the value
is recorded in the radio tag, and the identification information is
recorded in the side surface. In these cases, the storage unit need
not store which case contains a gaming chip of which identification
information.
[0085] In an inspection system according to an eighth aspect of the
first embodiment, in the inspection system of any one of the first
to seventh aspects, the determining unit determines that a
plurality of gaming chips contained in the case are fail when the
number of pieces of the first gaming chip information acquired by
the first reading device and the number of pieces of the second
gaming chip information acquired by the second reading device are
not a predetermined number.
[0086] With this configuration, when the gaming chip is withdrawn
from the case or the gaming chip is added to the case, the
determining unit can determine that the gaming chips contained in
the case are fail.
[0087] For example, when the number of gaming chips contained in
the case is 100, fail is determined when any one of the number of
pieces of the first gaming chip information read from the radio tag
and the number of pieces of the second gaming chip information read
from the side surface is not 100.

Structure of Gaming Chip
[0131] FIG. 2 is a perspective view of the gaming chip C according
to an embodiment of the present invention, and FIG. 3 is a side
view of the gaming chip C according to an embodiment of the present
invention. The gaming chip C has a designated color layer 501 which
is characterized by a designated color in the middle and a common
color layer 502 which is characterized by a common color on both
sides of the designated color layer 501 in the middle in a
thickness direction (upper and lower sides in FIG. 3), and a stripe
pattern (in the thickness direction) is formed on the side
surface.
[0132] An RFID tag 503 is inserted between the designated color
layer 501 and one common color layer 502 of the gaming chip C as a
radio tag. For example, individual identification information
individually identifying (uniquely specifying) the gaming chip C
and value (type) information are stored in the RFID tag 503 as the
gaming chip information of the gaming chip C. A transparent layer
504 is formed as the outermost layer of the gaming chip C. In other
words, the gaming chip C includes the designated color layer 501
which is an intermediate layer, the common color layers 502
sandwiching the designated color layer 501 from both sides, and the
transparent layers 504 which are the outermost layers of both
sides.
[0133] The gaming chip C is formed such that five elongated layers
of plastic materials (the transparent layer 504, the common color
layer 502, the designated color layer 501, the common color layer
502, and the transparent layer 504) are stacked, the RFID tag 503
is arranged between the designated color layer 501 and one common
color layer 502 at a predetermined interval at that time, and the
five layers of plastic materials are thermocompression bonded and
then punched into a circular shape, a rectangular shape, or the
like through a press so that one RFID tag 503 is included in one
gaming chip C. When the punching is performed through the press,
dimensions of a die and a punch of a mold for punching are
designed, and R treatment (rounded corner) is applied to the end of
the transparent layer 504 of the outermost layer.
[0134] The transparent layer 504 may be formed by thermocompression
bonding three layers including the designated color layer 501 and
the two common color layers 502 and then applying varnish to the
surface. Further, the designated color layer 501 and the two common
color layers 502 may not be separate members, and the designated
color layer 501 and the two common color layers 502 may be formed
by applying the designated color (and the common color) to the side
surface through inkjet printing or the like after the designated
color layer 501 and the two common color layers 502 are integrally
formed.
[0135] The designated color layer 501 indicates the value (type) of
the gaming chip C using a color (a designated color). In other
words, the color of the designated color layer 501 is set to a
different color (red, green, yellow, blue, or the like) in
accordance with the value of the gaming chip C, and thus it is
possible to specify the value of the gaming chip C (10 points, 20
points, 100 points, 1000 points, or the like) by checking the color
of the designated color layer 501 optically read from the side
surface of the gaming chip C. A color common to the gaming chips C
having different values (a common color) is assigned to the common
color layer 502. The common color is preferably a color lighter
than any designated color, and the common color is white in the
present embodiment.
[0136] Code information 505 indicating the gaming chip information
of the gaming chip C is further inscribed on the side surface of
the gaming chip C (specifically, the common color layer 502 of the
side surface). The code information 505 indicates information by
arranging a plurality of marks (square marks in the present
embodiment). Since the designated color layer 501 indicates
information (the value of the gaming chip C) with color, whereas
the code information 505 indicates information with a mark
inscribed on the side surface, the code information 505 can be
regarded as notation information. Examples of the notation
information include a plurality of character strings, a numeric
string, and a bar code.
[0137] The code information 505 of the present embodiment is
repeatedly inscribed with a cycle of 60.degree. in a
circumferential direction of the gaming chip C. Accordingly, the
perfect code information 505 is included within a range of
120.degree. in the circumferential direction regardless of a
direction in which the side surface of the gaming chip C is
observed in the circumferential direction. A repetition cycle of
the gaming chip C is not limited to 60.degree. and may be
repeatedly inscribed at equal intervals in the circumferential
direction at least three times.
[0138] The code information 505 is inscribed using invisible ink.
In the present embodiment, printing is performed by inkjet printing
using infrared absorbing ink (specifically, carbon black) that
absorbs infrared rays as the invisible ink. Since only a portion on
which the code information 505 is printed does not reflect infrared
rays, the code information 505 floats when the side surface of the
gaming chip C is photographed by the infrared camera 225. In order
to cause the printed portion to float clearly, the infrared camera
225 may be equipped with an infrared lamp and irradiate the side
surface of the gaming chip C to be photographed with infrared
rays.
[0139] Further, the invisible ink is not limited to the infrared
absorbing ink and may be, for example, infrared reaction ink that
emits fluorescence in response to infrared rays or UV ink which
emits fluorescence in response to ultraviolet rays. In the case of
using the UV ink, the ultraviolet camera is used in place of the
infrared camera 225, and black light which irradiates the side
surface of the gaming chip C with ultraviolet rays is used to cause
the UV ink to emit fluorescence.
[0140] Further, in the gaming chip C, a mark m' using the UV ink or
the carbon black ink is formed on a surface X of the common color
layer 502. The mark m' indicates whether the gaming chip 5 is true
or false, and the mark m' becomes visible when irradiated with
ultraviolet rays (or infrared rays), and it is indicated whether
the gaming chip 5 is true or false in accordance with a combination
of shapes of the mark m' and the number of marks m'. The
transparent layer 504 is thermocompression bonded or applied on the
outermost layer so as to cover a print 506 (such as 100 points) for
specifying the game hall or the mark m' on the surface, but
embossing treatment or vanish treatment is applied to the
transparent layer 504, and thus the gaming chips C are prevented
from adhering to each other, and slipping is further improved.
[0141] The R treatment (R) is performed on the end of the
transparent layer 504 of the outermost layer which has undergone a
print 506 (100 points or the like), and the surface of the common
color layer 502 is prevented from being deformed in the process of
punching the gaming chip C and appearing on the side surface.
Further, a sharp edge of the gaming chip C is prevented from
remaining and damaging a hand and other gaming chips C. The
designated color layer 501 may be formed by one or a plurality of
colored layers. Further, metal or ceramics for increasing the
weight of the layer may be formed in the layer of the designated
color layer 501. Further, the RFID tag 503 may be installed in a
space which is formed in a part of the designated color layer 501
or between the designated color layer 501 and the common color
layer 502.
[0142] FIG. 4 is a diagram illustrating an example of an image
obtained by photographing a plurality of gaming chips C contained
in the case 100 through the infrared camera 225 and the visible
light camera 226. In this case, the case 100 may be a two-stage
chip float (an upper tray portion which is particularly movable in
a two-stage chip tray) or a chip tray which holds the gaming chip C
in the game table. Even when the gaming chip C is stacked in the
case 100 in the vertical direction as illustrated in FIG. 4, the
infrared camera 225 and the visible light camera 226 can photograph
the code information 505. Further, it is possible to count the
number of gaming chips C by counting the designated color layer 501
in the vertical direction. Even with the two-stage tray, when each
stage is developed, it is possible to capture the side surfaces of
all the gaming chips C contained in the case 100 through the
infrared camera 225 and the visible light camera 226.
[0143] In the present embodiment, the code information 505 is
indicated by the marks m arranged in a plurality of rows and a
plurality of columns. FIG. 5 is a diagram for describing a
configuration of the code information 505. As illustrated in FIG.
5, upper and lower marks m are paired to form one code element. In
the example of FIG. 5, one piece of code information 505 is
configured with a 10-digit code element. There are four types of
patterns of one code element constituted by a pair of upper and
lower marks m, four types of information can be indicated by one
code element as illustrated in FIG. 5, and thus the code
information 505 configured with the 10-digit code element can
indicate 10-th power of 4 types of information. A character Y on
the side of the 10-digit code element is a direction determination
mark Y for determining the direction of the code information
505.
Configuration of Inspecting Device
[0144] FIG. 6 is a block diagram illustrating a configuration of
the inspecting device 200. The inspecting device 200 includes a bar
code reader 228 and a communication unit 229 in addition to the
RFID reader 221, the computer 222, the display unit 223, the RFID
antenna 224, the infrared camera 225, and the visible light camera
226 illustrated in FIG. 1. Further, the computer 222 is configured
with a processor (not illustrated), a memory, and the like and
functions as an identifying unit 230 and a determining unit 231
when the processor executes an inspection program.
[0145] An RFID system is configured with the RFID reader 221, the
RFID antenna 224, and the RFID tag 503 embedded in the gaming chip
C. The gaming chip information of the gaming chip C stored in the
RFID tag 503 embedded in the gaming chip C is read out by the RFID
reader 221 in a non-contact manner and used for a process in the
computer 222.
[0146] The infrared camera 225 includes an infrared transmission
filter that transmits only infrared light and captures an infrared
image. The infrared image generated by the photographing of the
infrared camera 225 is transmitted to the computer 222 and used for
a process of the identifying unit 230. The visible light camera 226
captures an image of light of a visible region. A visible light
image generated by the photographing of the visible light camera
226 is also transmitted to the computer 222 and used for a process
of the identifying unit 230. As illustrated in FIG. 1, the infrared
camera 225 and the visible light camera 226 are directed toward the
case 100 above the case 100, and photograph the side surfaces of a
plurality of gaming chips C in the case 100 over the upper portion
101 of the case 100.
[0147] The bar code reader 228 reads the bar code BC attached to
the case 100 and acquires case identification information to be
described later. The display unit 223 displays a determination
result of the determining unit 231 of the computer 222. The
communication unit 229 communicates data with a manufacturing
management device 302 installed in a factory F or a use management
device 303 installed in a game hall P.
Configuration of Case
[0148] FIG. 7 is a perspective view of a case 100. The case 100 is
formed by combining the upper portion 101 and the lower portion
102. In the present embodiment, the upper portion 101 and the lower
portion 102 are made of transparent resin. As described above,
since the infrared camera 225 and the visible light camera 226 of
the inspecting device 200 of the present embodiment (hereinafter
referred to simply as a "camera") installed above the receiving
unit 210, it is necessary for at least the upper surface of the
case 100 to transmit light. In other words, in the case 100, a
portion positioned between the receiving unit 210 of the inspecting
device 200 and the camera when the case 100 is received by the
receiving unit 210 of the inspecting device 200 needs to be a light
transmitting portion. In the present embodiment, the case 100 has a
sealed structure including the upper portion 101 and the lower
portion 102, but the light transmission portion may be in a
perforated state.
[0149] As described above, the case 100 has a shape in which the
five columns in which 20 gaming chips C are stacked and contained
are formed in parallel, and in the example of FIG. 7, a cross
section of each column is polygonal (octagonal) so that the upper
portion 101 and the lower portion 102 substantially follow the
shape of the gaming chip C to be contained.
[0150] FIG. 8 is a perspective view of a case 100' according to a
modified example, and FIG. 9 is a plan view of the case 100'. The
case 100' also includes an upper portion 101' and a lower portion
102 made of a transparent resin. In the present modified example,
the upper surface of the upper portion 101' facing the camera is
formed as a plane surface. Since the surface facing the camera is a
plane surface, a linear shadow caused by a corner of a polygon
cross section of the case 100' does not appear on the camera as
illustrated in FIG. 9, and it is possible to accurately identify
information of the side surface of the gaming chip C in image
analysis on a captured image of the camera.
Use State of Inspection System
[0151] FIG. 10 is a diagram for describing an example of a use
state of the inspection system 1 together with the distribution of
the gaming chips C. The gaming chip C is manufactured by a
manufacturing device 301 of a factory F (s1), and 100 gaming chips
C are contained in the case 100 (s2). The case 100 is sealed with a
seal at the factory F after the gaming chips C are contained.
Further, the bar code BC indicating the case identification
information uniquely specifying the case 100 is affixed to the side
surface of the case 100 (s3).
[0152] At this time, the case identification information of the bar
code BC affixed to the case 100 is input to the manufacturing
management device 302 in the factory F (s4). Further, the case 100
containing the gaming chips C is transferred to the inspecting
device 200, the gaming chip information (to be described later in
detail) assigned to the gaming chip C is read, and the pass/fail
inspection is performed. The gaming chip information read from the
gaming chip C contained in the case 100 is transferred to the
manufacturing management device 302 (s5) and associated with the
case identification information through the manufacturing
management device 302. The manufacturing management device 302 may
be a personal computer.
[0153] The case 100 determined to be pass in the inspecting device
200 of the factory F is conveyed from the factory F to a game hall
P (s6). The case 100 is first stored in a storage R in the game
hall P (s7). The inspecting device 200 is installed in the storage
R, and the case 100 that arrived from the factory F is inspected
through the inspecting device 200.
[0154] Meanwhile, the case identification information and the
gaming chip information associated with the case identification
information are transmitted from the manufacturing management
device 302 in the factory F to the use management device 303 in the
game hall P. The use management device 303 acquires the case
identification information and the gaming chip information
associated with the case identification information from the
manufacturing management device 302 for each of a plurality of
cases 100 containing the gaming chip C and includes a storage unit
that stores the acquired information for each case 100. The use
management device 303 may be a personal computer.
[0155] In the inspection performed by the inspecting device 200 in
the storage R, an inspection is performed using the information
stored in the use management device 303. The case 100 determined to
be pass in the inspection in the storage R is carried to a game
table T (s9) or carried to a cashier CA (s10). Each of the game
table T and the cashier CA includes the inspecting device 200, and
the case 100 containing the gaming chip C is inspected by the
inspecting devices 200 in a sealed state. In the game table T and
the cashier CA, the case 100 containing used gaming chips C is also
inspected, and the inspecting device 200 is also used for the
inspection. In the inspection in the three inspecting devices 200
in the game hall P, the case identification information transmitted
from the manufacturing management device 302 and stored in the use
management device 303 and the gaming chip information associated
with the case identification information are referred to.
Configuration of Stored Information
[0156] FIG. 11 is a diagram illustrating an example of content of
information which is generated by the manufacturing management
device 302, transmitted to the use management device 303, and
stored in the use management device 303. Information is generated
for each case 100, and the gaming chip information of a plurality
of gaming chips C (100 gaming chips in the present embodiment)
contained in the case 100 is associated with each piece of case
identification information (Ca1, Ca2, Ca3, . . . ).
[0157] As the gaming chip information, information including a
combination of the individual identification information (aa, ab,
ac, . . . , du, dv) uniquely specifying the gaming chip C and
information (r, r, r, . . . , b, b) specifying the value (type) of
the gaming chip C is stored in the RFID tag 503, information
including a combination of individual identification information
(00001, 00002, 00003, . . . , 00099, 00100) uniquely specifying the
gaming chip C and information (1, 1, 1, . . . , 2, 2) specifying
the value (type) of the gaming chip is stored as the notation
information of the side surface, and information (red, red, red, .
. . , blue, blue) specifying the value (type) of the gaming chip C
is stored as the color information of the side surface.
[0158] The information stored in the RFID tag 503 is information
which is electromagnetically readable by the RFID reader 221 and
corresponds to first gaming chip information of the present
invention, and the notation information assigned to the side
surface and the color information are optically readable
information and correspond to second gaming chip information of the
present invention.
Configuration of Read Information
[0159] FIG. 12 is a diagram illustrating an example of content of
information acquired from one case 100 through the bar code reader
228, the RFID reader 221, the infrared camera 225, and the visible
light camera 226 in the inspecting device 200. An English character
string stored in the RFID tag 503 installed in each of a plurality
of gaming chips C is read out from the RFID reader 221. A numeric
string which is the notation information inscribed on the side
surface is read out from the infrared camera 225. Further, the
color of the side surface is read out from the visible light camera
226. The identifying unit 230 analyzes (the image of) the numeric
string read out from the infrared camera 225, identifies a number,
specifies information including the numeric string, and specifies
the designated color from the image of the side surface read out
from the visible light camera 226.
[0160] Here, the notation information and the designated color
information of the side surface of a plurality of gaming chips C
can be acquired in accordance with an arrangement order of the
gaming chips C in the case 100, but the information acquired from a
plurality of RFID tags 503 is unable to be acquired in accordance
with the arrangement order of the gaming chips C. In other words,
it is difficult to specify a gaming chip C from which the
information of the RFID tag 503 is obtained.
Pass/Fail Determination Method
[0161] Next, a pass/fail determination method in the computer 222
of the inspecting device 200 will be described. As described above,
the identifying unit 230 specifies the gaming chip information
stored in the RFID tags 503 of each of a plurality of gaming chips
C contained in the case 100 on the basis of a result of reading the
RFID reader 221, analyzes the infrared image obtained by the
infrared camera 225, specifies the gaming chip information
indicated by the notation information, analyzes the visible light
image obtained by the visible light camera 226, and specifies the
color of the designated color layer 501. On the basis of the
information, the determining unit 231 determines the
authenticity/damage of all the gaming chips contained in the case
or the number of gaming chips of each value on the basis of the
information, and determines whether the case 100 is pass or fail.
In the following description, the gaming chip information stored in
the RFID tag 503 is referred to as "first gaming chip information",
and the notation information assigned to the side surface of the
gaming chip C and the color information of the designated color
layer 501 are referred to as "second gaming chip information".
(First Pass/Fail Determination Method)
[0162] In a first pass/fail determination method, the first gaming
chip information and the second gaming chip information in the same
gaming chip are the same information as illustrated in FIG. 13. In
an example of FIG. 13, the first gaming chip information is
information including the individual identification information and
the value information of each gaming chip C, and the same content
as the first gaming chip information is inscribed on the side
surface in a form of the notation information as the second gaming
chip information.
[0163] The RFID reader 221 reads the first gaming chip information
from the RFID tag 503 of the gaming chip C and outputs the first
gaming chip information to the identifying unit 230, the infrared
camera 225 photographs the side surface of the gaming chip C, and
the identifying unit 230 specifies the second gaming chip
information. In this case, in the identifying unit 230, a
correspondence relation between a plurality of pieces of first
gaming chip information and a plurality of pieces of second gaming
chip information is unclear.
[0164] The determining unit 231 compares a plurality of pieces of
first gaming chip information obtained by the identifying unit 230
with a plurality of pieces of second gaming chip information, and
when a plurality of pieces of first gaming chip information
completely correspond to a plurality of pieces of second gaming
chip information in a one-to-one manner, that is, when all pieces
of first gaming chip information coincide with any one of second
gaming chip information without overlapping, the determining unit
231 determines that a plurality of gaming chips C contained in the
case 100 are pass, but when a plurality of pieces of first gaming
chip information obtained by the identifying unit 230 do not
completely coincide with a plurality of pieces of second gaming
chip information, the determining unit 231 determines that a
plurality of gaming chips C contained in the case 100 are fail.
[0165] As a case in which a plurality of pieces of first gaming
chip information obtained by the identifying unit 230 do not
completely coincide with a plurality of pieces of second gaming
chip information, there is a case in which any one of the gaming
chips C contained in the case 100 is a fake or a case in which the
RFID tag 503 or the side surface of the gaming chip C is damaged.
In other words, the determining unit 231 determines whether a
plurality of gaming chips C contained in the case 100 are pass or
fail by determining the authenticity/damage of all the gaming chips
contained in the case 100.
(Second Pass/Fail Determination Method)
[0166] In a second pass/fail determination method, the first gaming
chip information and the second gaming chip information in the same
gaming chip C are the same information as illustrated in FIG. 14.
In an example of FIG. 14, the first gaming chip information is the
value information of each gaming chip C, and in each gaming chip C,
the designated color is assigned to the designated color layer 501
of the side surface as the second gaming chip information.
[0167] The RFID reader 221 reads out the first gaming chip
information from the RFID tag 503 of the gaming chip C and outputs
the first gaming chip information to the identifying unit 230, the
visible light camera 226 photographs the side surface of the gaming
chip C, and the identifying unit 230 analyzes the image and
specifies the second gaming chip information (the color of the
designated color layer 501).
[0168] In this case, in the identifying unit 230, a correspondence
relation between a plurality of pieces of first gaming chip
information and a plurality of pieces of second gaming chip
information is unclear, a plurality of pieces of first gaming chip
information may overlap each other, and a plurality of pieces of
second gaming chip information may also overlap with each other. In
the first gaming chip information and the second gaming chip
information of FIG. 14, "r" indicates red, "b" indicates blue, "y"
indicates yellow, and "g" indicates green.
[0169] When the number of each of all the designated colors (red,
blue, yellow, and green) in a plurality of pieces of first gaming
chip information obtained by the identifying unit 230 coincides
with the number of each of all the designated colors (red, blue,
yellow, and green) in a plurality of pieces of second gaming chip
information, the determining unit 231 determines "pass", and
otherwise, the determining unit 231 determines "fail".
[0170] As a case in which the number of each of all the designated
colors in the first gaming chip information does not coincide with
the number of each of all the designated colors in a plurality of
pieces of second gaming chip information, there is a case in which
any one of the gaming chips C contained in the case 100 is a fake
or a case in which the side surface of any of the gaming chips C is
damaged. In other words, the determining unit 231 determines
whether a plurality of gaming chips C contained in the case 100 are
pass or fail by determining the number of all the gaming chips C
contained in the case 100 for each value.
(Third Pass/Fail Determination Method)
[0171] In a third pass/fail determination method, the first gaming
chip information and the second gaming chip information in the same
gaming chip C are different information as illustrated in FIG. 15.
In an example of FIG. 15, information of an English character
string is stored in the RFID tag 503 of the gaming chip C as the
first gaming chip information, and the notation information of a
numeric string is inscribed on the side surface of the gaming chip
C as the second gaming chip information.
[0172] The RFID reader 221 reads out the first gaming chip
information from the RFID tag 503 of the gaming chip C and outputs
the first gaming chip information to the identifying unit 230, the
infrared camera 225 photographs the side surface of the gaming chip
C, and the identifying unit 230 specifies the second gaming chip
information. In this case, in the identifying unit 230, a
correspondence relation between a plurality of pieces of first
gaming chip information and a plurality of pieces of second gaming
chip information is unclear.
[0173] The first gaming chip information and the second gaming chip
information are stored in the use management device 303 in
association with the case identification information of the case
100. The determining unit 231 compares a plurality of pieces of
first gaming chip information obtained by the identifying unit 230
with a plurality of pieces of first gaming chip information
associated with the case identification information of the case 100
stored in the use management device 303, and determines whether or
not they completely correspond to each other in a one-to-one
manner. The determining unit 231 compares a plurality of pieces of
second gaming chip information obtained by the identifying unit 230
with a plurality of pieces of second gaming chip information
associated with the case identification information of the case 100
stored in the use management device 303 and determines whether or
not they completely correspond to each other in a one-to-one
manner.
[0174] When a plurality of pieces of first gaming chip information
obtained by the identifying unit 230 completely correspond to a
plurality of pieces of first gaming chip information associated
with the case identification information of the case 100 stored in
the use management device 303 in a one-to-one manner, that is, a
plurality of pieces of first gaming chip information obtained by
the identifying unit 230 coincide with any one of a plurality of
pieces of first gaming chip information associated with the case
identification information of the case 100 stored in the use
management device 303 without overlapping, and a plurality of
pieces of second gaming chip information obtained by the
identifying unit 230 completely correspond to a plurality of pieces
of second gaming chip information associated with the case
identification information of the case 100 stored in the use
management device 303 in a one-to-one manner, that is, a plurality
of pieces of second gaming chip information obtained by the
identifying unit 230 coincide with any one of a plurality of pieces
of second gaming chip information associated with the case
identification information of the case 100 stored in the use
management device 303 without overlapping, the determining unit 231
determines that a plurality of gaming chips C contained in the case
100 are pass, and when any one of a plurality of pieces of first
gaming chip information does not coincide or any one of a plurality
of pieces of second gaming chip information does not coincide, the
determining unit 231 determines that a plurality of gaming chips C
contained in the case 100 are fail.
[0175] As a case in which one of a plurality of pieces of first
gaming chip information does not coincide with the stored
information or one of a plurality of pieces of second gaming chip
information does not coincide with the stored information, there is
a case in which any one of gaming chips C contained in the case 100
is a fake or a case in which the RFID tag 503 or the side surface
of the gaming chip C is damaged. In other words, the determining
unit 231 determines whether or not a plurality of gaming chips C
contained in the case 100 are pass or fail by determining the
authenticity/damage of all the gaming chips C contained in the case
100.
(Fourth Pass/Fail Determination Method)
[0176] In a fourth pass/fail determination method, the first gaming
chip information and the second gaming chip information in the same
gaming chip C are different information as illustrated in FIG. 16.
In an example of FIG. 16, information of an English character
string is stored in the RFID tag 503 of the gaming chip C as the
first gaming chip information, and the designated color layer 501
of the side surface of the gaming chip C is colored in the
designated color corresponding to the value as the second gaming
chip information.
[0177] The RFID reader 221 reads out the first gaming chip
information from the RFID tag 503 of the gaming chip C and outputs
the first gaming chip information to the identifying unit 230, the
visible light camera 226 photographs the side surface of the gaming
chip C and outputs a captured image to the identifying unit 230,
and the identifying unit 230 analyzes the captured image and
specifies the designated color which is the second gaming chip
information. In this case, in the identifying unit 230, a
correspondence relation between a plurality of pieces of first
gaming chip information and a plurality of pieces of second gaming
chip information is unclear.
[0178] The first gaming chip information and the second gaming chip
information are stored in the use management device 303 in
association with the case identification information of the case
100. The determining unit 231 compares a plurality of pieces of
first gaming chip information obtained by the identifying unit 230
with a plurality of pieces of first gaming chip information
associated with the case identification information of the case 100
stored in the use management device 303 and determines whether or
not they completely correspond to each other in a one-to-one
manner. The determining unit 231 compares the number of each
designated color in a plurality of pieces of second gaming chip
information obtained by the identifying unit 230 with the number of
each designated color in a plurality of pieces of second gaming
chip information associated with the case identification
information of the case 100 stored in the use management device
303, and determines whether or not the numbers of designated colors
coincide with each other.
[0179] When a plurality of pieces of first gaming chip information
obtained by the identifying unit 230 completely correspond to a
plurality of pieces of first gaming chip information associated
with the case identification information of the case 100 stored in
the use management device 303, and the number of each of all the
designated colors in a plurality of pieces of second gaming chip
information obtained by the identifying unit 230 coincide with the
number of each of all the designated colors in a plurality of
pieces of second gaming chip information associated with the case
identification information of the case 100 stored in the use
management device 303, the determining unit 231 determines the case
100 to be "pass", and when any one of a plurality of pieces of
first gaming chip information does not coincide, and the number of
any one of the designated colors in a plurality of pieces of second
gaming chip information does not coincide, the determining unit 231
determines the plurality of gaming chips C contained in the case
100 to be "fail".
[0180] As a case in which one of a plurality of pieces of first
gaming chip information does not coincide with the stored
information or the number of any of the designated colors in a
plurality of pieces of second gaming chip information does not
coincide, there is a case in which any one of gaming chips C
contained in the case 100 is a fake or a case in which the RFID tag
503 or the side surface of the gaming chip C is damaged. In other
words, the determining unit 231 determines whether or not a
plurality of gaming chips C contained in the case 100 are pass or
fail by determining the authenticity/damage of all the gaming chips
C contained in the case 100 and the number of gaming chips C for
each value.
(Fifth Pass/Fail Determination Method)
[0181] In a fifth pass/fail determination method, the first gaming
chip information and the second gaming chip information in the same
gaming chip C are different information as illustrated in FIG. 17.
In an example of FIG. 17, the individual identification information
including a numeric string is stored in the RFID tag 503 of the
gaming chip C as the first gaming chip information, and the value
information of the gaming chip C is assigned to the side surface of
the gaming chip C as the second gaming chip information in the form
of the designated color of the designated color layer 501.
[0182] The RFID reader 221 reads out the first gaming chip
information from the RFID tag 503 of the gaming chip C and outputs
the first gaming chip information to the identifying unit 230, the
visible light camera 226 photographs the side surface of the gaming
chip C and outputs a captured image to the identifying unit 230,
and the identifying unit 230 analyzes the captured image and
specifies the designated color which is the second gaming chip
information. In this case, in the identifying unit 230, a
correspondence relation between a plurality of pieces of first
gaming chip information and a plurality of pieces of second gaming
chip information is unclear.
[0183] The correspondence relation between the first gaming chip
information and the second gaming chip information is stored in the
use management device 303. In an example of FIG. 17, the individual
identification information uniquely specifying the gaming chip C is
associated with the designated color of the designated color layer
501 of the side surface, that is, the value information of the
gaming chip C, and it is possible to understand the value of the
gaming chip C when the individual identification information is
designated. In the case of the present example, the use management
device 303 need not store a combination of the first gaming chip
information and the second gaming chip information for each piece
of case identification information. In other words, in the present
example, the gaming chips C contained in case 100 can be inspected
without using the case identification information.
[0184] The determining unit 231 specifies the first gaming chip
information corresponding to the first gaming chip information
identified by the identifying unit 230 from the first gaming chip
information stored in the use management device 303 and specifies
the second gaming chip information associated with the first gaming
chip information, that is, the value. The determining unit 231 can
obtain the number of each value in a plurality of pieces of second
gaming chip information extracted from the use management device
303 for one case by performing the above process on all pieces of
the first gaming chip information identified by the identifying
unit 230.
[0185] The determining unit 231 compares the number of each value
obtained as described above with the number of each value in the
second gaming chip information identified for the case 100 from the
identifying unit 230. When the numbers of each of all the values
coincide, the determining unit 231 determines that a plurality of
gaming chips C contained in the case 100 are pass, and when the
number of any one of the values does not coincide, the determining
unit 231 determines that a plurality of gaming chips C contained in
the case 100 are fail.
[0186] As a case in which the number of each value in a plurality
of pieces of second gaming chip information extracted from the use
management device 303 does not coincide with the number of each
value in the second gaming chip information identified for the case
100 from the identifying unit 230, there is a case in which any one
of gaming chips C contained in the case 100 is a fake or a case in
which the RFID tag 503 or the side surface of the gaming chip C is
damaged. In other words, the determining unit 231 determines
whether or not a plurality of gaming chips C contained in the case
100 are pass or fail by determining the authenticity/damage of all
the gaming chips C contained in the case 100 and the number of
gaming chips C for each value.
[0187] Although not illustrated, even when the value of the gaming
chip C is stored as the first gaming chip information, and the
individual identification information of the gaming chip C is
stored as the second gaming chip information, the pass/fail
determination can be performed similarly to the above example.
[0188] The first to fifth pass/fail determination methods have been
described above, but the determining unit 231 may employ a
combination of the above pass/fail determination methods. In
addition to the above pass/fail determination methods, when both
the number of pieces of first gaming chip information and the
number of pieces of second gaming chip information read from a
plurality of gaming chips C contained in the case 100 are not a
predetermined number (100 in the present embodiment), the
determining unit 231 may determine that a plurality of gaming chips
C contained in the case 100 are fail.
[0189] The first and second pass/fail determination methods are
pass/fail determination methods that can be executed without using
the information stored in the use management device 303 installed
in the game hall P and suitable when executed by the inspecting
device 200 in the factory F, the third to fifth pass/fail
determination methods are pass/fail determination methods using the
information stored in the use management device 303 installed in
the game hall P and suitable when executed by the inspecting device
200 in the game hall P, but the inspecting device 200 in the game
hall P may employ the first or second pass/fail determination
method. When all the inspecting devices 200 in the game hall P
employ the pass/fail determination method in which the information
stored in the use management device 303 is not used such as the
first or second pass/fail determination method, the use management
device 303 may be omitted.
[0190] Further, the inspecting device 200 in the game hall P also
inspects the case 100 containing the used gaming chips C, but in
the case, the first, second, or fifth pass/fail determination
method in which information of the gaming chips to be contained in
the case need not be stored may be employed.
[0191] Further, in the above embodiment, the gaming chip C includes
the individual identification information and/or the value
information as the first gaming chip information and/or the second
gaming chip information. Here, the individual identification
information is information uniquely specifying each gaming chip C,
whereas the value information is information that can overlap each
other in a plurality of gaming chips C and can be regarded as
information (group information) indicating a group to which each
gaming chip belongs. In the present embodiment, as the group
information of the associated group, instead of the value or in
addition to the value, for example, information of a gaming chip
manufacturing time, a manufacturer, and/or a game hall in which a
gaming chip is used may be employed.
[0192] In other words, both the first gaming chip information and
the second gaming chip information may include the individual
identification information identifying the gaming chip, the first
gaming chip information and the second gaming chip information may
include the group information indicating the group to which the
gaming chip belongs, the first gaming chip information may include
the individual identification information identifying the gaming
chip, and the second gaming chip information may include the group
information of the group to which the gaming chip belongs, or, the
first gaming chip information may include the group information of
the group to which the gaming chip belongs, and the second gaming
chip information may include the individual identification
information identifying the gaming chip.
Pass/Fail Determination Result Display
[0193] FIGS. 18 and 19 are diagrams illustrating an example of a
pass/fail determination result display screen illustrating a
pass/fail determination result in the determining unit 231. These
pass/fail result display screens are generated by the computer 222
on the basis of the pass/fail determination result in the
determining unit 231 and displayed on the display unit 223. FIG. 18
illustrates an example of a display screen in the case of "pass",
and FIG. 19 illustrates an example of a display screen in the case
of "fail".
[0194] As illustrated in FIGS. 18 and 19, a pass/fail result
display screen 800 includes a total of the number of detections 801
which is the number of combinations of the first gaming chip
information and the second gaming chip information read out from
the gaming chip C by the identifying unit 230, the number of
authorized gaming chips C 802, and the number of unauthorized
gaming chips C 803.
[0195] The computer 222 sets a larger one of the number of pieces
of first gaming chip information and the number of pieces of second
gaming chip information as the total of the number of detections
801. For example, when 100 gaming chips C are contained in the case
100, and one of the 100 gaming chips C has no RFID tag 503 therein,
the identifying unit 230 specifies 100 pieces of second gaming chip
information from a plurality of gaming chips C but obtains only 99
pieces of first gaming chip information. In this case, the computer
222 sets 100 which is the larger of the first gaming chip
information and the second gaming chip information as the total of
the number of detections 801.
[0196] In the case of the first or second pass/fail determination
method, the computer 222 decides the number of combinations of the
first gaming chip information and the second gaming chip
information that are determined to coincide with each other as the
number of authorized gaming chips C 802, and decides a number
obtained by subtracting the number of authorized gaming chips C
from the total of the number of detections 801 as the number of
unauthorized gaming chips C 803.
[0197] In the case of the third or fourth pass/fail determination
method, the computer 222 decides a smaller one of the number of
pieces of first gaming chip information in which the correspondence
relation with the first gaming chip information stored in the use
management device 303 has been confirmed and the number of pieces
of second gaming chip information in which the correspondence
relation with the second gaming chip information stored in the use
management device 303 has been confirmed as the number of
authorized gaming chips C 802, and decides a number obtained by
subtracting the number of authorized gaming chips C from the total
of the number of detections 801 as the number of unauthorized
gaming chips C 803.
[0198] In the case of the fifth pass/fail determination method, the
computer 222 decides the number of pieces of second gaming chip
information in which the correspondence relation with the second
gaming chip information stored in the use management device 303 has
been confirmed as the number of authorized gaming chips C 802, and
decides a number obtained by subtracting the number of authorized
gaming chips C from the total of the number of detections 801 as
the number of unauthorized gaming chips C 803.
[0199] The pass/fail result display screen 800 includes a gaming
chip information display portion 804 that displays the gaming chip
information read out from the gaming chip C through the identifying
unit 230. In the gaming chip information display portion 804, when
the gaming chip information stored in the use management device 303
is read or when the first gaming chip information coincides with
the second gaming chip information, the gaming chip information is
colored and displayed, and the gaming chip information which is
stored in the use management device 303 but not read out is
displayed in white (see FIG. 19).
[0200] In the pass/fail result display screen 800, when the gaming
chip information not stored in the use management device 303 is
read or when the first gaming chip information does not coincide
with the second gaming chip information, the gaming chip
information is displayed outside the gaming chip information
display portion 804 as unauthorized gaming chip information
805.
Modified Example
(RFID Antenna of Inspecting Device)
[0201] FIG. 20 is a diagram illustrating an RFID antenna 224 of the
inspecting device 200 according to a modified example. In FIG. 20,
the arm 227, the infrared camera 225, and the visible light camera
226 are not illustrated. In the above embodiment, the RFID antenna
224 is installed in the left and right sidewalls 211, but the RFID
antenna 224 may be installed in an inner wall 213. In this case,
the RFID antenna 224 is arranged in a spiral shape inside the inner
wall 213.
(Gaming Chip)
[0202] FIG. 21 is a side view of a gaming chip C' according to a
modified example. In the gaming chip C of the above embodiment, the
designated color layer 501 is sandwiched between the common color
layers 502, but in the example of FIG. 21, in the gaming chip C', a
common color layer 502 is formed as the center, and the designated
color layer 501 is formed as both (upper and lower) sides. In the
example of FIG. 21, individual identification information indicated
by a 7-digit numeric string is inscribed (printed) on the side
surface of the gaming chip C' as code information 505'. In the
example of FIG. 21, the code information 505' serving as the
notation information is inscribed on the common color layer 502 in
the middle. In this case, the code information 505' can indicate
10-th power of 7 types of information.
[0203] Further, both the code information 505 indicated by the
presence/absence of the mark m described for the gaming chip C of
the above embodiment and the code information 505' of the numeric
string illustrated in FIG. 21 are inscribed on the side surface of
the gaming chip C. In this case, the code information 505 of the
mark m and the code information 505' of the numeric string may be
printed with different types of ink. For example, the code
information 505 of the mark m may be printed with the infrared
reaction ink, and the code information 505' of the numeric string
may be printed with the UV reactive ink. In this case, an infrared
camera and an ultraviolet camera may be prepared to photograph the
side surface of the gaming chip C, the code information 505 of the
mark m may be read by the infrared camera, and the code information
505' of the numeric string may be read by the ultraviolet
camera.
[0204] FIG. 22 is a side sectional view of the gaming chip C''
according to another modified example. The gaming chip C'' has a
multi-layer structure in which a plurality of plastic layers having
different colors are stacked, a designated color layer 501 (a
colored layer) is arranged at least in the middle, and a common
color layer (a white or light-colored layer) 502 are stacked on
both sides of the designated color layer 501 in the middle. It is
desirable that the color of the common color layer 502 be thinner
than the color of the designated color layer 501. Since the gaming
chip C'' has a multi-layer structure in which the designated color
layer 501 is arranged, and the common color layer 502 is stacked on
both sides of the designated color layer 501 in the middle as
described above, it is possible to specify a type of gaming chip
C'' (10 points, 20 points, 100 points, 1,000 points, or the like)
by forming a stripe pattern on the side surface in a stack
direction and changing the color of the designated color layer 501
(red, green, yellow, blue, or the like) as illustrated in FIG.
23.
[0205] FIG. 23 is a perspective view of stacked gaming chips C'',
FIG. 24 is a side view of the gaming chip C'', and FIG. 25 is a
plan view of the gaming chip C''. As illustrated in FIG. 23, the
gaming chip C'' has a five or more-layer structure in which a print
507 (100 points or the like) indicating a type (value) of gaming
chip C'' is performed on the surface (the upper surface and the
lower surface) of the common color layer 502, a transparent layer
504 is formed as the outermost layer, and the respective layers are
thermocompression-bonded. The gaming chip C'' is formed using an
elongated plastic material such that a state in which the
respective layers (the designated color layer 501, the common color
layer 502, and the transparent layer 504) are
thermocompression-bonded and adhered to each other in an elongated
stated (a five-layer structure or the like) is formed and then
punched out into a circular shape, a rectangular shape, or the like
through a process or the like. When the punching is performed
through the press, dimensions of a die and a punch of a mold for
punching are designed, and R treatment (rounded corner) is applied
to the end of the transparent layer 504 of the outermost layer.
[0206] Further, in the gaming chip C'', the mark m'' is formed on
the surface of common color layer 502 using the UV ink or the
carbon black ink. The mark m'' indicates whether the gaming chip
C'' is true or false, and the mark m'' becomes visible when
irradiated with ultraviolet rays (or infrared rays), and it is
indicated whether the gaming chip C'' is true or false in
accordance with a combination of shapes of the mark m'' and the
number of marks m''. The transparent layer 504 is thermocompression
bonded or applied on the outermost layer so as to cover the print
507 or the mark m', but embossing treatment is applied to the
transparent layer 504, and thus the gaming chips C'' are prevented
from adhering to each other.
[0207] The R treatment (R) is performed on the end of the
transparent layer 504 of the outermost layer which has undergone a
print 507 (100 points or the like), and the surface of the common
color layer 502 is prevented from being deformed in the process of
punching the gaming chip C'' and appearing on the side surface.
Further, a sharp edge of the gaming chip C'' is prevented from
remaining and damaging a hand and other gaming chips C''.
[0208] As illustrated in FIG. 22, the designated color layer 501
may be formed by a plurality of layers colored in the designated
color (three layers in FIG. 22). Since a plurality of layers
colored in the designated color (three layers in FIG. 22) are
thermocompression bonded to each other, the three-layer structure
is not visible as illustrated in FIG. 22, and FIG. 22 illustrates
the three layers of the designated color layer 501 for the sake of
description. Further, a partial hollow B is formed in a middle
layer among the three layers of the designated color layer 501, and
a RFID tag 503 is installed in the partial hollow B.
[0209] Since the gaming chip C, C', and C'' have a stacked
multi-layer structure, and a stripe pattern in the lamination
direction is vividly formed on the side surface as illustrated in
FIG. 2, FIG. 21, and FIG. 22, it is possible to easily and
accurately measure the color of the designated color layer 501 (the
type of gaming chip) and the number of designated color layers 501
through image analysis as compared with a chip of a related art.
FIG. 26 is a diagram illustrating an example of an image obtained
by photographing the stacked gaming chips. As illustrated in FIG.
26, it is possible to photograph the side surface of the gaming
chip C through the visible light camera 226 and clearly identify
the designated color layer 501. Further, it is possible to
accurately analyze and determine an image when an artificial
intelligence utilization type computer or control system or a deep
learning (structure) technique is used in the image analysis. Since
the artificial intelligence utilization type computer or control
system or the deep learning (structure) technique is known to those
skilled in the art, detailed description thereof is omitted.
(Detection of Seal)
[0210] As described above, the case 100 is sealed with a seal after
a predetermined number of gaming chips C are contained. The seal is
broken when the case is opened to allow the contained gaming chips
to be withdrawn. The inspecting device 200 may include a detecting
unit that detects an unbroken seal affixed to the case 100. The
detecting unit may detect the seal optically or magnetically. In
this case, when an unbroken seal is not detected by the detecting
unit, the determining unit 231 determines that a plurality of
gaming chips C contained in the case 100 are fail.
(Arrangement of Components of Inspecting Device)
[0211] In the above embodiment, all the components of the
inspecting device 200 are arranged in a single device as
illustrated in FIG. 6, but the components may be distributedly
arranged. For example, some or all of the computer 222, the display
unit 223, and the communication unit 229 may be implemented by a
personal computer connected to the inspecting device 200. The
distributedly arranged components may be connected to be able to
perform wired or wireless communication or may be connected via a
network such as the Internet.
[0212] Further, as illustrated in FIGS. 27 and 28, the infrared
camera 225 and/or the visible light camera 226 and the arm 227 may
be separated from the inspecting device 200, and the cameras may be
connected to the computer 222. FIG. 27 illustrates an example in
which only one of the infrared camera 225 and the visible light
camera 226 is installed separately from the inspecting device 200,
and FIG. 28 illustrates an example in which the infrared camera 225
is installed separately from the inspecting device 200, and the
visible light camera 226 is installed integrally with the
inspecting device 200. Further, in addition to the infrared camera
225 and the visible light camera 226, an ultraviolet camera may be
installed as a third camera together with an ultraviolet lamp, or
one of the cameras in FIGS. 27 and 28 may be an ultraviolet camera
equipped with an ultraviolet lamp.
(Gaming Chip Information)
[0213] In the above embodiment, in the gaming chip C, the gaming
chip information is stored in the RFID tag 503, the code
information 505 serving as the gaming chip information is inscribed
on the side surface, the designated color of the designated color
layer 501 of the side surface is also dealt as the gaming chip
information indicating the value of the gaming chip C, and one
gaming chip C has the three pieces of gaming chip information, but
the present invention is not limited to this example, and the
gaming chip C may has only two of the three pieces of gaming chip
information. When the gaming chip C has two pieces of gaming chip
information, the first to fifth pass/fail determination methods can
be executed.
[0214] In the above first to fifth pass/fail determination methods,
two pieces of gaming chip information are used, but when the gaming
chip C has three pieces of gaming chip information, the determining
unit 231 performs the pass/fail determination using the three
pieces of gaming chip information.
(Display Unit)
[0215] In the above embodiment, the example in which the display
unit 223 is configured with a liquid crystal panel has been
described, but the display unit 223 may be a lamp that simply
indicates only whether it is pass or fail or may be a lamp that
performs digital display of the total of the number of detections
801, the number of authorized gaming chips C 802, and the number of
unauthorized gaming chips C 803.
(Total Amount Calculation of Value)
[0216] The determining unit 231 of the above embodiment is able to
specify the number of each of the values of a plurality of gaming
chips C contained in the case 100 as described above. In this
regard, the determining unit 231 may further calculate a total
amount of the values of a plurality of gaming chips C contained in
the case 100 on the basis of the number of each value. The
calculated total amount may be displayed on the pass/fail result
display screen (see FIGS. 18 and 19) displayed on the display unit
223.
Second Embodiment
[0217] A second embodiment relates to an inspection system and an
inspecting device which are capable of inspecting the gaming chips,
and more particularly to, an inspection system and an inspecting
device which are capable of inspecting the gaming chips having a
radio tag embedded therein or counting the number of gaming
chips.
[0218] A gaming chip having a radio tag storing identification
information or type information therein is known (for example, JP
2008-246103 A).
[0219] A gaming chip having a structure in which a radio tag is not
easily extracted is disclosed in JP 2008-246103 A. Accordingly, a
structure in which the radio tag hardly has a defect is
implemented.
[0220] However, when the number of gaming chips disclosed in JP
2008-246103 A is read by the radio tag, since the number of gaming
chips is calculated on the basis of the read radio tag information,
gaming chip information is unable to be acquired when the radio tag
installed in the gaming chip is broken or when no radio tag is
installed, and there is a problem in that there is a difference
between the actual number of gaming chips and the number of gaming
chips calculated by reading the radio tag.
[0221] In this regard, it is an object of the present invention to
provide an inspection system and an inspecting device which are
capable of detecting whether or not the radio tag is broken.
[0222] An Inspection system according to a first aspect of the
second embodiment is an inspection system that inspects gaming
chips each having a color or a display indicating a value on an
outer surface in a state where the gaming chips are stored in a
case in which a maximum of the number of gaming chips to be stored
is limited, a radio tag storing gaming chip information being
embedded in each of the gaming chips, the gaming chips being stored
in the case capable of containing a row of gaming chips stacked in
a thickness direction, the inspection system including: a reading
device that reads the radio tag of the gaming chip in the case and
acquires gaming chip information of the gaming chip; and a
determining unit that compares the gaming chip information acquired
by the reading device with a maximum of the number of gaming chips
storable in the case and determines an abnormality of the gaming
chip in the case when the number of gaming chips obtained from the
gaming chip information acquired by the reading device is different
from a maximum of the number of storable gaming chips.
[0223] Further, the determining unit has a function of comparing a
physical characteristic of the case or physical information of the
gaming chip obtained from a physical measurement means other than
the reading device with the number of pieces of physical
information of the gaming chip obtained from the gaming chip
information acquired by the reading device, determining that there
is an abnormal gaming chip among the gaming chips contained in the
case when both pieces of information do not coincide with each
other, and outputting a determination result.
[0224] Further, the physical information is a number or height
which is obtained optically or a weight which is obtained by
measurement.
[0225] Further, the inspection system may further include a radio
tag information database which is able to refer to information of
the radio tag embedded in the gaming chip, and the determining unit
may be configured to compare the gaming chip information of the
gaming chip read by the reading device with the information of the
radio tag information database and detect an abnormality of a
gaming chip of an inspection target.
[0226] Further, the determining unit may have a function of
comparing, when it is determined that there is an abnormal gaming
chip among the gaming chips in the case, the information of the
radio tags of all the gaming chips in the case with the radio tag
information database registered in advance and specifying the
presence of an abnormal radio tag which is not stored in the radio
tag information database.
[0227] Further, the determining unit may have a function of
specifying, when it is determined that there is an abnormal gaming
chip among the gaming chips in the case, the presence of an
abnormal gaming chip in which information from the radio tag is
unable to be obtained among the gaming chips in the case.
[0228] Further, the determining unit may have a function of
analyzing the information of the radio tag acquired by the reading
device and issuing a signal when two or more gaming chips having
the same information obtained from the radio tag are contained in
the case.
[0229] Further, the radio tag information database may be an
information database of radio tags of gaming chips being stored or
used in a game hall, and the determining unit may have a function
of analyzing the information of the radio tag acquired by the
reading device and issuing a signal when information obtained from
the radio tag coincides with information of a radio tag of a gaming
chip placed in a different place in the game hall.
[0230] An inspecting device according to a second aspect of the
second embodiment is inspecting device that inspects gaming chips
each having a color or a display indicating a value on an outer
surface, a radio tag storing gaming chip information being embedded
in each of the gaming chips, the inspecting device including: an
inspection table capable of inspecting the gaming chips in a state
where the gaming chips are stacked in a row in a thickness
direction, and a maximum of the number of stackable gaming chips is
limited; a reading device that reads the radio tags of the row of
gaming chips and acquires the gaming chip information of the row of
gaming chips; and a determining unit that compares the gaming chip
information acquired by the reading device with a maximum of the
number of stackable gaming chips of the inspection table and
determines an abnormality of the gaming chip placed on the
inspection table when the number of gaming chips obtained from the
gaming chip information acquired by the reading device is different
from a maximum of the number of stackable gaming chips.
[0231] Further, the determining unit may have a function of
determining, when the gaming chip information of the gaming chip
acquired by the reading device does not coincide with physical
information of the gaming chip, the presence of an abnormal gaming
chip among the gaming chips placed on the inspection table and
outputting a determination result.
[0232] Further, the physical information may be a number or height
which is obtained optically or a weight which is obtained by
measurement.
[0233] Further, the inspecting device may further include a radio
tag information database which is able to refer to information of
the radio tag embedded in the gaming chip, and the determining unit
may be configured to compare the gaming chip information of the
gaming chip read by the reading device with the information of the
radio tag information database and detect an abnormality of a
gaming chip of an inspection target placed on the inspection
table.
[0234] Further, the determining unit may have a function of
comparing, when it is determined that there is an abnormal gaming
chip among the gaming chips on the inspection table, the
information of the radio tags of all the gaming chips on the
inspection table with the radio tag information database registered
in advance and specifying the presence of an abnormal radio tag
which is not stored in the radio tag information database.
[0235] Further, the determining unit may have a function of
specifying, when it is determined that there is an abnormal gaming
chip among the gaming chips in the case, the presence of an
abnormal gaming chip in which information from the radio tag is
unable to be obtained among the gaming chips in the case.
[0236] Further, the determining unit may have a function of
analyzing the information of the radio tag acquired by the reading
device and issuing a signal when two or more gaming chips having
the same information obtained from the radio tag are contained in
the case.
[0237] Further, the radio tag information database may be an
information database of radio tags of gaming chips being stored or
used in a game hall, and the determining unit may have a function
of analyzing the information of the radio tag acquired by the
reading device and issuing a signal when information obtained from
the radio tag coincides with information of a radio tag of a gaming
chip placed in a different place in the game hall.
[0238] According to the present embodiment, since the gaming chips
are stored in the case in which the number of storable gaming chips
is decided, and the number of gaming chips is determined, it is
possible to perform the inspection so that it is possible to detect
whether or not the radio tag is broken.
[0239] The second embodiment will be described below with reference
to the accompanying drawings.
Configuration of Inspection System
[0240] FIG. 29 is a diagram illustrating a configuration of an

the lower portion 5102 are made of transparent resin. In the
present embodiment, the case 5100 has a sealed structure including
the upper portion 5101 and the lower portion 5102, but the light
transmission portion may be in a perforated state.
[0250] As described above, the case 5100 has a shape in which the
five columns 5100C in which 20 gaming chips C are stacked and
contained are formed in parallel, and in the example of FIG. 31, a
cross section of each column is polygonal (octagonal) so that the
upper portion 5101 and the lower portion 5102 substantially follow
the shape of the gaming chip C. Each column 5100C has a shape in
which 21 or more gaming chips C are unable to be contained.
[0251] FIG. 32 is a perspective view of a case 5100' according to a
modified example, and FIG. 33 is a plan view of the case 5100'. The
case 5100' also includes of an upper portion 5101' and a lower
portion 5102 made of a transparent resin. In the present modified
example, the upper surface of the upper portion 5101' facing the
camera is formed as a plane surface. Since the surface facing the
camera is a plane surface, a linear shadow caused by a corner of a
polygon cross section of the case 5100' does not appear on the
camera as illustrated in FIG. 33, and it is possible to accurately
identify information of the side surface of the gaming chip C in
image analysis on a captured image of the camera.
(Gaming Chip)
[0252] FIG. 34 is a side sectional view of the gaming chip C of the
present embodiment. The gaming chip C has a multi-layer structure
in which a plurality of plastic layers having different colors are
stacked, a designated color layer 5501 (a colored layer) is
arranged at least in the middle, and a common color layer (a white
or light-colored layer) 5502 are stacked on both sides of the
designated color layer 5501 in the middle.
[0253] As illustrated in FIG. 34, the designated color layer 5501
may be formed by a plurality of layers colored in the designated
color (three layers in FIG. 34). Since a plurality of layers
colored in the designated color (three layers in FIG. 34) are
thermocompression bonded to each other, the three-layer structure
is not visible as illustrated in FIG. 34, and FIG. 34 illustrates
the three layers of the designated color layer 5501 for the sake of
description. Further, a partial hollow B is formed in a middle
layer among the three layers of the designated color layer 5501,
and a radio tag 5503 is installed in the partial hollow B.
[0254] The inspection system 51 inspects the gaming chips C each

information of the radio tag 5503 embedded in the gaming chip C,
and the determining unit 5222 is configured to compare the gaming
chip information of the gaming chip C read by the reading device
5221 with the information database 5303 of the radio tag 5503 and
detect an abnormality of a gaming chip C of an inspection target.
The information database 5303 stores information of all the radio
tags 5503 of the gaming chips used in the game hall in advance.
[0256] The determining unit 5222 has a function of comparing, when
it is determined that there is an abnormal gaming chip C among the
gaming chips C in the case 5100, the information of the radio tags
5503 of all the gaming chips C in the case 5100 with the
information database 5303 of the radio tag 5503 registered in
advance and specifying the presence of an abnormal radio tag 5503
which is not stored in the information database of the radio tag
5503.
[0257] The determining unit 5222 has a function of specifying, when
it is determined that there is an abnormal gaming chip C among the
gaming chips C in the case 5100, the presence of an abnormal gaming
chip C in which information from the radio tag 5503 is unable to be
obtained among the gaming chips C in the case 5100.
[0258] The display unit 5223 displays an abnormality when it is
determined that there is an abnormal gaming chip C described
above.
[0259] As illustrated in FIGS. 36 and 37, a pass/fail result
display screen 5800 includes a total of the number of detections
5801 which is the number of pieces of information of the radio tag
5503 read out from the gaming chip C by the identifying unit 5230
and the number of unauthorized gaming chips C 5803.
[0260] FIGS. 36 and 37 are diagrams illustrating an example of the
pass/fail result display screen illustrating a result of
determining the abnormality of the gaming chip in the
identification content determining unit 5231. The pass/fail result
display screens are generated on the basis of the result of
determining the abnormality of the gaming chip in the
identification content determining unit 5231 by the determining
unit 5222 and displayed on the display unit 5223. FIG. 36
illustrates an example of a display screen in the case of "pass",
and FIG. 37 illustrates an example of a display screen in the case
of "fail".
[0261] FIG. 38 is a diagram illustrating an inspecting device 5400
according to another modified example. The inspecting device 5400
inspects the gaming chip C having the radio tag 5503 storing the

determination result.
Use State of Inspection System
[0264] FIG. 39 is a diagram for describing an example of a use
state of the inspection system 1 along with the distribution of the
gaming chips C. The gaming chip C is manufactured by a
manufacturing device 5301 of a factory F (s1), and 100 gaming chips
C are contained in the case 5100 (s2). The case 5100 is sealed with
a seal at the factory F after the gaming chips C are contained.
Further, the bar code BC indicating the case identification
information uniquely identifying the case 5100 is affixed to the
side surface of the case 5100 (s3).
[0265] At this time, the case identification information of the bar
code BC affixed to the case 5100 is input to the manufacturing
management device 5302 in the factory F (s4). Further, the case
5100 containing the gaming chips C is transferred to the inspecting
device 5200, the gaming chip information (to be described later in
detail) assigned to the gaming chip C is read, and the pass/fail
inspection is performed. The gaming chip information read from the
gaming chip C contained in the case 5100 is transferred to the
manufacturing management device 5302 (s5) and associated with the
case identification information through the manufacturing
management device 5302. The manufacturing management device 5302
may be a personal computer.
[0266] The case 5100 determined to be pass in the inspecting device
5200 of the factory F is conveyed from the factory F to a game hall
P (s6). The case 5100 is first stored in a storage R in the game
hall P (s7). The inspecting device 5200 is installed in the storage
R, and the case 5100 that arrived from the factory F is inspected
through the inspecting device 5200.
[0267] Meanwhile, the case identification information and the
gaming chip information associated with the case identification
information are transmitted from the manufacturing management
device 5302 in the factory F to the information database 5303 in
the game hall P. The information database 5303 acquires the case
identification information and the gaming chip information
associated with the case identification information from the
manufacturing management device 5302 for each of a plurality of
cases 5100 containing the gaming chip C and includes a storage unit
that stores the acquired information for each case 5100. The
information database 5303 may be a personal computer.
[0268] In the inspection performed by the inspecting device 5200 in
the storage R, an inspection is performed using the information
stored in the information database 5303. The case 5100 determined
to be pass in the inspection in the storage R is carried to a game
table T (s9) or carried to a cashier CA (s10). Each of the game
table T and the cashier CA includes the inspecting device 5200, and
the case 5100 containing the gaming chip C is inspected by the
inspecting devices 5200 in a sealed state. In the game table T and
the cashier CA, the case 5100 containing used gaming chips C is
also inspected, and the inspecting device 5200 is also used for the
inspection. In the inspection in the three inspecting devices 5200
in the game hall P, the case identification information transmitted
from the manufacturing management device 5302 and stored in the
information database 5303 and the gaming chip information
associated with the case identification information are referred
to.
[0269] Further, in the above embodiment, the gaming chip C includes
the identification information and/or the value information as the
radio tag information. Here, the identification information is
information uniquely specifying each gaming chip C, whereas the
value information is information that can overlap each other in a
plurality of gaming chips C and can be regarded as information
(group information) indicating a group to which each gaming chip
belongs. In the present embodiment, as the group information of the
associated group, instead of the value or in addition to the value,
for example, information of a gaming chip manufacturing time, a
manufacturer, and/or a game hall in which a gaming chip is used may
be employed.
[0270] In other words, the radio tag information may include the
identification information identifying the gaming chip or may
include the group information indicating the group to which the
gaming chip belongs.
(Detection of Seal)
[0271] As described above, the case 5100 is sealed with a seal
after a predetermined number of gaming chips C are contained. The
seal is broken when the case is opened to allow the contained
gaming chips to be withdrawn. The inspecting device 5200 may
include a detecting unit that detects an unbroken seal affixed to
the case 5100. The detecting unit may detect the seal optically or
magnetically. In this case, when an unbroken seal is not detected
by the detecting unit, the identification content determining unit
5231 determines that a plurality of gaming chips C contained in the
case 5100 are fail.
(Arrangement of Components of Inspecting Device)
[0272] In the above embodiment, all the components of the
inspecting device 5200 are arranged in a single device as
illustrated in FIG. 30, but the components may be distributedly
arranged. For example, some or all of the determining unit 5222,
the display unit 5223, and the communication unit 5229 may be
implemented by a personal computer connected to the inspecting
device 5200. The distributedly arranged components may be connected
to be able to perform wired or wireless communication or may be
connected via a network such as the Internet.
(Display Unit)
[0273] In the above embodiment, the example in which the display
unit 5223 is configured with a liquid crystal panel has been
described, but the display unit 5223 may be a lamp that simply
indicates only whether it is pass or fail or may be a lamp that
performs digital display of the total of the number of detections
5801, the number of authorized gaming chips C 5802, and the number
of unauthorized gaming chips C 5803.
(Total Amount Calculation of Value)
[0274] As described above, the identification content determining
unit 5231 of the above embodiment can specify the number of each of
the values of a plurality of gaming chips C contained in the case
5100. In this regard, the identification content determining unit
5231 may calculate a total amount of the values of a plurality of
gaming chips C contained in the case 5100 further on the basis of
the number of each value. The calculated total amount may be
displayed on the pass/fail result display screen (see FIGS. 36 and
37) displayed on the display unit 5233.
