Description
TECHNICAL FIELD
[0001] The present invention relates to a medal tray provided for a
medal game machine as a portion where medals are ejected.
BACKGROUND ART
[0002] A medal game machine is provided with a medal tray as a
portion where medals are ejected. In a medal tray of this type, a
front wall is provided with its height lower than that of rear and
side walls so that medals accumulated on the bottom wall can be
easily taken out.
DISCLOSURE OF INVENTION
Problem to be solved by the Invention
[0003] Medals ejected to the medal tray tend to stack along the
rear wall. To prevent medals from dropping from the short front
wall, the medal ejection position in the medal tray is often set
near the rear wall. When medals are piled up high near the rear
wall, however, even if the medal tray has a sufficient depth, the
periphery of the medal ejection port is likely to become clogged
with the ejected medals, and the player has to frequently arrange
the pile state of the medals.
[0004] An object of the present invention is therefore to provide a
medal tray realizing a proper medal pile state.
Means for Solving the Problem
[0005] The present invention solves the above problem by the
following means.
[0006] The present invention solves the above problem by a medal
tray provided for a medal game machine as a portion where medals
are ejected the medal tray comprises a bottom wall on which medals
are accumulated and side and rear walls surrounding three sides of
the bottom wall, wherein the rear wall is provided with a
protrusion portion for regulating accumulation of medals along the
rear wall, so that the protrusion portion projects forward and is
disposed above the bottom wall so as to be separated from the
bottom wall.
[0007] According to the invention, by providing the rear wall with
the protrusion portion, near the rear wall, accumulation of medals
between the bottom wall and the protrusion portion is regulated,
and medals exceeding the regulation are accumulated forward.
Consequently, there is no possibility that medals are unlimitedly
piled up along the rear wall, and the apex of a mountain formed by
accumulation of medals gets shifted forward. Thus, the medal
ejection space is assured on the rear wall side while preventing
clogging of medals, and a larger number of medals can be
accumulated on the bottom wall without arrangement by the
player.
[0008] In the medal tray of the invention, a medal ejection port
may be provided in the rear wall, and the protrusion portion may be
disposed between the medal ejection port and the bottom wall. In
this case, since the protrusion portion is interposed between the
medal ejection port and the bottom wall, closing of the medal
ejection port with medals on the bottom wall is suppressed.
[0009] Further, a curved wall may be provided between the bottom
wall and the protrusion portion. In the case where such a curved
wall is provided, there is no possibility that medals are clogged
between the bottom wall and the protrusion portion. The protrusion
portion may be tapered in the vertical direction from the base
portion joined to the rear wall toward the tip. By employing such a
tapered shape, while suppressing decrease in volume of the medal
tray due to provision of the protrusion portion, an effect of the
protrusion portion can be sufficiently obtained. The protrusion
portion may be provided along the overall length in the width
direction of the rear wall. By providing the protrusion portion
along the overall length in the width direction, the effect of the
projection can be maximally obtained. The present invention may be
also embodied as a medal game machine having the described medal
tray.
Effect of the Invention
[0010] As described above, according to the invention, there is no
possibility that medals are unlimitedly piled up along the rear
wall, and the apex of a mountain formed by accumulation of medals
gets shifted forward. Thus, the medal ejection space is assured on
the rear wall side while preventing clogging of medals, and a
larger number of medals can be accumulated on the bottom wall
without arrangement by the player.

BEST MODE FOR CARRYING OUT THE INVENTION
[0055] FIGS. 1 to 3 show an embodiment of a game machine to which
the present invention is applied. FIG. 1 is a front view, FIG. 2 is
a plan view, and FIG. 3 is a right side view. As obviously
understood from the diagrams, a game machine 1 is constructed as a
commercial game machine (so-called arcade game machine) which is
set in a commercial facility such as a game hall and providing a
game within a predetermined range in compensation for consumption
of an economic value of a player, and includes a main unit 2, and
three sub units 3 disposed in the center of the front face of the
main unit 2 and on the right and left sides of the front face
respectively. Each of the sub units 3 can be installed in a proper
position apart from the main unit 2. The economic value in the game
machine 1 is consumed by insertion of medals into the sub unit
3.
(Configuration of Main Unit)
[0056] As specifically shown in FIGS. 4 to 6, the main unit 2 has a
chassis 5 which can stand by itself on the floor of a shop or the
like. The chassis 5 is constructed by using wood or a resin
material like a normal game machine. A monitor 6 is mounted on the
left side of the front face of the chassis 5 and a lottery machine
7 is mounted on the right side of the monitor 6. As the monitor 6,
a large display such as a liquid crystal projector or a plasma
display is preferably used. Obviously, a liquid crystal display or
a CRT may be also used as the monitor. The lottery machine 7 will
be described later.
[0057] The chassis 5 of the main unit 2 is provided with various
decorations to improve the decorating effect of the game machine 1.
For example, decorations 8 are provided on the outside of the
monitor 6 and the lottery machine 7. Similarly, to improve the
decorating effect of the game machine 1, a sail 10 is provided on a
top face 5a of the chassis 5. As shown in FIGS. 5 and 6, the sail
10 has a frame work 11 and a screen 12 stretched on the surface of
the frame work 11. The frame work 11 is constructed by combining
plural vertical frames 13 and plural lateral frames 14. On the
other hand, the screen 12 is constructed by, for example, vinyl
cloth or sailcloth of white. The screen 12 is fixed to the surface
of the frame work 11 so as to have proper slackness between the
vertical frames 13. For fixing the screen 12, various means may be
used.
[0058] A cover 5b covering the lower part of the sail 10 is fixed
to the front edge of the top face 5a of the chassis 5. On the back
side of the cover 5b, plural frame supporting plates 15 are
provided so as to stand in parallel with the anteroposterior
direction of the chassis 5 and upright at intervals in the
horizontal direction (the horizontal direction of FIG. 1) of the
chassis 5. Each of the frame supporting plates 15 is fixed to the
top face 5a and the cover 5b of the chassis 5 by using bolts 16. A
frame holder 17 is attached to each of the frame supporting plates
15. With respect to the two frame supporting plates 15 on this side
of FIG. 6, the frame holders 17 are provided on the back side and
are not seen.
[0059] As specifically shown in FIG. 7, the frame holder 17 has a
cylindrical body of a square shape in cross section with one side
face open. Flanges 17a (only one side is shown in FIG. 7) are
provided at both edges of the opening. The frame holder 17 is fixed
onto the frame supporting plate 15 by screwing a bolt 18 attached
to the flange 17a into the frame supporting plate 15. By attaching
the frame holder 17 to the frame supporting plate 15, an elongated
cavity is formed between the frame supporting plate 15 and the
frame holder 17. By inserting the bottom end of the vertical frame
13 into the cavity, the sail 10 is attached onto the chassis 5 in a
state where the sail 10 is tilted so as to project at the front
side of the game machine 1 towards the top end thereof.
[0060] In the frame supporting plate 15, plural screw holes 19 into
which the bolts 18 attached to the bottom end of the frame holder
17 are to be screwed are formed. The screw holes 19 are provided
along an arc having a predetermined radius of curvature around a
fulcrum as a center which is set on the top end side of the frame
holder 17. Although not shown, screw holes corresponding to the
bolts 18 attached to the top end side of the frame holder 17 are
also provided along an arc having a predetermined radius of
curvature around the fulcrum as a center. On the top end side, any
one of the screw holes may be used as the fulcrum for changing the
tilt angle of the frame holder 17. Therefore, by changing the screw
hole 19 to which the bolt 18 is to be screwed, the tilt of the
frame holder 17 is changed and thereby, the tilt angle of the sail
10 can be changed. When the vertical frames 13 are pulled out from
the frame holder 17, the sail 10 itself can be detached from the
chassis 5.
[0061] As shown in FIGS. 4 to 6, a light box 20 is provided at the
bottom end on the front side of the chassis 5. As shown in FIGS. 8
and 9, the light box 20 has a closed cabinet 21 and can be detached
from the chassis 5. A top face 21a of the cabinet 20 is inclined
and a transparent panel 22 is provided almost in the full length in
the width direction (corresponding to the horizontal direction of
the chassis 5) of the light box 20 in part of the top face 21a. A
projector 23 is disposed in the cabinet 21 so as to face the
transparent panel 22. The projector 23 is for projecting a figure
or the like printed on a slide 24 by illumination light emitted
from a light source 25. The direction of projection is set to the
vertical direction. As obvious from FIG. 5, the light box 20 is
disposed on the front side of the chassis 5 so that the transparent
panel 22 is positioned just below the sail 10. With the
configuration, the illumination light of the projector 23 can be
received by the screen 12 of the sail 10 and an image of the figure
or the like of the slide 24 can be projected onto the screen 12.
FIG. 10 shows an example. An image projected onto the screen 12 may
be a still picture or a motion picture. The slide 24 may not be
provided and a dynamic image may be formed on the screen 12 by
changing the colors, patterns, and the like of the illumination
light from the light source 25.
[0062] When the sub units 3 are disposed around the chassis 5 as
shown in FIGS. 1 to 3, the position of each of the sub units 3 is
set so as not to overlap the optical path extending from the
projector 23 to the screen 12. By surrounding the light box 20 with
the sub units 3, there is no possibility that a player or the like
enters the optical path extending from the projector 23 to the
screen 12.
[0063] FIGS. 11 and 12 show the main portion of the lottery machine
7. As shown in FIG. 11, the lottery machine 7 has a cabinet 30, a
drum 31 disposed on the front side of the cabinet 30 so as to be
turnable around the axis in the anteroposterior direction, and an
indicator 32. A ball path 33 is provided around the drum 31. As
shown in FIG. 10, the surface of the drum 31 is equally divided
into eight pieces in the circumferential direction and numbers 1 to
8 are indicated in the areas respectively.
[0064] As shown in FIG. 12, the cabinet 30 has therein a ball
loading mechanism 34, a drum driving motor 35, an indicator driving
mechanism 36, and a ball collecting mechanism 37. The ball loading
mechanism 34 loads a ball B for lottery (refer to FIG. 11) into the
ball path 33 in response to a load instruction given from the
control system of the game machine 1 to the lottery machine 7. The
drum drive motor 35 rotates the drum 31 around its axis as a
center. The indicator driving mechanism 36 monitors whether or not
the ball B drops in a pocket 38 provided just below the drum 31 and
continued from the ball path 33. In response to detection of drop
of the ball B into the pocket 38, the indicator driving mechanism
36 moves the indicator 32 from a standby position P1 in which the
indicator 32 lies horizontally to an action position P2 in which
the indicator 32 lies vertically as shown in FIG. 11. The tip of
the indicator 32 is formed in a needle shape and can selectively
point one of the areas on the drum 31 in the action position
P2.
[0065] The ball B dropped in the pocket 38 is led to the ball
collecting mechanism 37 via a duct 39. The ball collecting
mechanism 37 gives the ball B back to the ball loading mechanism 34
and is constructed, for example, so as to carry the ball B received
from the duct 39 upward in the vertical direction by a teethed belt
37a which runs in the vertical direction and pass the ball B to a
ball holding part 34a of the ball loading mechanism 34 around the
turn position at the top end of the belt 37a.
[0066] Such a lottery machine 7 is provided to select one of the
numbers 1 to 8 provided on the drum 31 and its function is realized
as follows. First, when a lottery start instruction is given from
the control system of the game machine 1 to the lottery machine 7,
in response to the instruction, the drum driving motor 35 is driven
to start rotating the drum 31. Subsequently, when a ball loading
instruction is given to the ball loading mechanism 34, the ball B
is loaded to the ball path 33. When the loaded ball B reaches the
pocket 38, the indicator driving mechanism 36 is driven to drive
the indicator 32 to the action position P2. Synchronously, the drum
driving motor 35 is stopped so that it is seen as if the drum 31
was pressed by the indicator 32 and stopped. After the drum 31
stops, the number indicated by the tip of the indicator 32 is
specified by the rotation position of the drum driving motor 35
(for example, it is detected by an encoder), and one of the numbers
1 to 8 is determined as the number chosen by the lottery. The ball
B in the pocket 38 is returned by the ball collecting mechanism 37
for the next lottery. The front side of the lottery machine 7 is
covered with a transparent cover to prevent the ball B from jumping
out or the like. The lottery probability may be changed by varying
the time relation between the timing the ball B reaches the pocket
38 and the timing the drum 31 stops within the range the player
does not notice. Such an operation can be used for adjusting, for
example, a payout ratio. As long as any of the numbers can be
selected, the lottery machine 7 is not limited to the
above-described configuration. The configuration may be properly
changed.
(Configuration of Sub Unit)
[0067] The sub unit 3 will now be described with reference to FIG.
13 and subsequent drawings. Since each of the three sub units 3 has
the same configuration as each other, one of the sub units 3 will
be described below. As shown in FIGS. 13 to 16, in the subunit 3,
right and left two stations 40 are integrated on a single chassis
41. The station 40 is the minimum unit of the place where the
player plays a game. As obviously understood with reference to
FIGS. 1 and 3, the height of the chassis 41 of the sub unit 3 is
regulated so as not to hide the monitor 6 and the main part
(including the drum 31 and the pocket 38) of the lottery machine 7
of the main unit 2. Although a medal hopper for holding and
ejecting medals is provided in the chassis 41, it is not shown.
[0068] Referring again to FIGS. 13 to 16, a game space 42 is
provided above the chassis 41, and a game board 43 is constructed
for each of the stations 40 on the bottom side of the game space
42. The details of the game board 43 will be described later.
Between the game boards 43, a medal ejecting device 44 shared by
the stations 40 is disposed. To prevent an access to the game board
43 by the player, the game space 42 is covered with a transparent
cover 45 (which is showed to be opaque in FIGS. 14 to 16). A
control panel 46 is provided on the front side of the chassis 41.
The control panel 46 is provided with a pair of right and left
medal loading devices 47 for each station 40. The medal loading
device 47 is provided to load a medal as a game medium by rolling
it in a state where the medal stands in the vertical direction, and
the tip of the medal inserting device 47 penetrates the cover 45
and is inserted in the game space 42. To enable the medal loading
direction to be adjusted according to the intension of the player,
the direction of the medal loading device 47 is made adjustable at
least in the horizontal direction. As the medal loading device 47,
a heretofore known medal shooter commonly used for a so-called
pusher game may be used.
[0069] The control panel 46 has a push-button type operation switch
48 which is provided for each station 40. The operation switch 48
is operated by the player to instruct, for example, the timing of
loading the ball B by the lottery machine 7. Obviously, the
operation switch 48 may be provided for other purposes.
[0070] The control panel 46 also has a medal tray 50 for each
station 40. The medal tray 50 is provided as a place to which
medals obtained by the player are ejected. FIGS. 17 and 18 show the
details of the medal tray 50. The medal tray 50 is obtained by
process a plate made of a metal material such as a stainless steel
plate, and has a rectangular bottom wall 51, a front wall 52
disposed around the bottom wall 51, right and left side walls 53
and 54, and a rear wall 55. The side walls 53 and 54 have flanges
53a and 54a, respectively, for attaching the medal tray 50 to the
chassis 41. In the top end of the front wall 52, a turn-back
portion 52a is formed outward.
[0071] The top face side of the medal tray 50 is open and the
height of the front wall 52 is set sufficiently lower than the
other walls 53 to 55, so that the player can take out medals. As
obvious from FIG. 18, the front wall 52 has the function of
preventing medals M from dropping forward of the medal tray 50 and
holding the medals M in a state where the medals M are stacked on
the bottom wall 51. It is therefore desirable to set the height of
the front wall 52 as large as possible in a range where taking of
the medals M is not hindered. There is, however, a case where the
front wall 52 is not always necessary such as a case where the
bottom wall 51 has a sufficiently large area. It is also possible
to incline upward the front part of the bottom wall 51 and omit the
front wall 52.
[0072] In the left wall 53, a slit-shaped medal ejection port 53b
which is long in the vertical direction for ejecting the medals M
to the medal tray 50 is provided nearer to the rear wall 55 side
than the front wall 52. An L-shaped cover 56 extending so as to
cover the medal ejection port 53b is provided at the top end of the
rear wall 55. Further, the rear wall 55 is provided with a
protrusion portion 57 extending almost in the overall length in the
width direction (the direction perpendicular to the drawing sheet
in FIG. 18) of the medal tray 50. The protrusion portion 57 is
disposed above the bottom wall 51 so that a space for receiving the
medals M is created between the protrusion portion 57 and the
bottom wall 51. The protrusion portion 57 is formed in a tapered
shape so as to be narrowed in the vertical direction from the base
portion joined to the rear wall 55 toward the tip. Such a
protrusion portion 57 is provided by bending a plate member in a V
shape and joining the bent plate member to the rear wall 55. The
protrusion portion 57 may be formed by various methods such as a
pulling material, casting, and the like. The position of the
protrusion portion 57 is set just below the medal ejection port 53b
and the tip of the protrusion portion 57 almost coincides with that
of the cover 56. The position of the bottom end of the protrusion
portion 57 also almost coincides with the top end of the front wall
52. Further, a curved wall 58 having an arc shape in cross section
is provided between the bottom wall 51 and the protrusion portion
57.
[0073] In the medal tray 50 as described above, the medals M
ejected from the medal ejection port 53b into the tray 50 are
guided by the protrusion portion 57 and dropped onto the bottom
wall 51 to be stacked. Since the rear wall 55 is provided with the
protrusion portion 57, the medals M are not likely to be stacked
while leaning against the rear wall 55 as shown by an imaginary
line M' in FIG. 18. Consequently, as shown by an imaginary line L1
in FIG. 18, a pile of the medals M stacked on the bottom wall 51
extends from its apex so as to be uniform in the anteroposterior
direction of the tray 50 (the horizontal direction of FIG. 18).
That makes hard for the medals M to stack around the medal ejection
port 53b, and a relatively large number of medals M can be
accumulated in the medal tray 50. If the protrusion portion 57 does
not exist, the medals M' leaning against the rear wall 55 are
stacked. As a result, as shown by an imaginary line L2, the medals
M are stacked so as to form a downward gradient from the rear wall
55 to the front wall 52, and clogging around the medal ejection
port 53b tends to occur early. Therefore, the number of medals M
which can be accumulated in the medal tray 50 without arrangement
by the player becomes smaller than the number in the medal tray 50
of this embodiment.
[0074] The details of the game board 43 will now be described with
reference to FIGS. 19 to 31. The configurations of the game boards
43 are common, so that one of the game boards 43 will be described
hereinbelow. As shown in FIG. 19, the game board 43 has, in order
from the upstream side (corresponding to the depth side) in the
medal flowing direction to the downstream side (on front side), a
monitor 60, a medal ejection port 61, an upper table 62, a medal
guiding device 63, a checker 64, and a lower table 65. The monitor
60 is provided as display means for executing a game and making
various dramatic presentations in each station 40. The medal
ejection port 61 is disposed just below the monitor 60. Medals sent
from a medal hopper in the chassis 41 to the medal guide 66 are
ejected from the medal ejection port 61 toward the upper table 62.
The upper table 62 is provided so as to be movable between a
horizontal position indicated by the solid lines in the diagram and
an action position in which the upper table 62 is lifted upward by
using the front edge 62a as a fulcrum as shown by imaginary lines
in the diagram.
[0075] FIGS. 20 to 24 show the details of a portion extending from
the upper table 62 to the lower table 65. A medal guide plate 67 is
provided above the lower table 65. The medal guide plate 67 is
transparent, and two medal guide plates 67 are provided for each
station 40 so as to have a one-to-one corresponding relation with
the medal loading devices 47. In FIGS. 20 and 21, only the medal
guide plate 67 corresponding to the right-side medal loading device
47 is shown. As obviously understood from FIGS. 22 and 24, the
medal guide plate 67 is tilted downward toward the depth side (the
side on which the monitor 60 is provided) of the game board 43 and
the center in the horizontal direction. The medal M loaded from the
medal loading device 47 rolls on the medal guide plate 67 while
changing its direction toward the center along the slope of the
medal guide plate 67 and drops onto the medal guiding device 63.
The medal guiding device 63 guides the medals M to the checker 64
while arranging the direction of the medals M in the
anteroposterior direction of the game board 43. The details will be
described later.
[0076] The checker 64 is fixed in a predetermined position on the
game board 43, and a number of slit-shaped medal pass holes 64a are
provided on the top face side of the checker 64. The medal pass
hole 64a extends in the anterposterior direction of the game board
43. The medals M dropped from the medal guiding device 63 to the
checker 64 can be divided into medals which have passed the medal
pass holes 64a and medals which have not passed the medal pass
holes 64a in accordance with the drop positions. The medal M passed
through the medal pass hole 64a is taken into the checker 64 and
returned to the medal hopper in the chassis 41. On the other hand,
the medal M which has not passed the medal pass hole 64a drops onto
the lower table 65.
[0077] Although not shown, a number of medals are stacked flat on
the lower table 65. A pusher 68 is provided on the depth side of
the lower table 65. As shown well in FIG. 23, the pusher 68 is
supported on the lower table 65 via rollers 69 disposed on the
front and rear sides. Consequently, the pusher 68 can shuttle in
the anteroprosterior direction along the lower table 65. Each of
FIGS. 19 to 24 shows a state where the pusher 68 is positioned
backward. The pusher 68 is driven between the position shown in the
diagrams and a position protruding forward by a not-shown pusher
driving mechanism. As the pusher driving mechanism, any of various
mechanisms used in heretofore known pusher game machines such as a
mechanism of converting rotation of a motor to reciprocating motion
of the pusher 68 by a slider crank mechanism may be employed.
[0078] By the reciprocation of the pusher 68 in the longitudinal
direction, the medals dropped onto the lower table 65 are pushed
and a pileup occurs in the medals on the lower table 65. Depending
on the degree of the pileup, a medal drops from the front edge 65a
or a side edge 65b of the lower table 65 (refer to FIG. 20). The
dropped medal is collected by the not-shown medal hopper. Medals
dropped from the front edge 65a are detected by a not-shown medal
drop sensor, and medals are ejected from the medal hopper to the
medal tray 50 in accordance with the number of detected medals.
[0079] The details of the medal guiding device 63 will now be
described with reference to FIGS. 25 to 31. As shown in FIG. 25,
the medal guiding device 63 has a guide block 70 and a driving
mechanism 71 for driving the guide block 70. FIGS. 29 to 31 show
the details of the guide block 70. The guide block 70 is obtained
by arranging and attaching plural (ten pieces in the diagram) of
medal guide members 73 at equal pitches in a predetermined
direction on a common base board 72. The medal guide member 73 is a
resin molded product whose lower part has a rectangular
parallelepiped shape and having, on the top face side, a medal
receiving face 73a of a semi-cylinder shape. A synthetic resin used
for the medal guide member 73 has to have proper abrasion
resistance to abrasion with the medal. For example, POM is suitably
used as the material of the medal guide member 73. A projection 73b
is provided at the top of the medal guide member 73. The projection
73b extends in the axial direction of the medal receiving face 73a,
in other words, in the anteroposterior direction of the game board
43. The range in which the projection 73b is provided is regulated
to the rear half of the medal guide member 73 with respect to the
anteroposterior direction of the game board 43. A gap 74 is
provided between the neighboring medal guide members 73 on the base
board 72. The gap 74 is slightly larger than the thickness of the
medal. Although the gaps 74 may be provided at predetermined
intervals, in this embodiment, the gap 74 gradually increases
toward the checker 64. With the configuration, when plural medals
drop in the gap 74 at the same time, the medals are prevented from
being clogged in the gap 74.
[0080] As shown in FIGS. 30 and 31, each medal guide member 73 is
individually attached from the under face side of the base board 72
by using a fitting screw 75. Therefore, when a specific medal guide
member 73 becomes dirty or is damaged, only the medal guide member
73 can be detached from the base board 72 for replacing. A base 76
is attached to the under face side of the base board 72. The base
76 has a supporting part 76a for supporting the guide block 70 and
a coupling part 76b extending rearward from the supporting part
76a. The supporting part 76a is inclined forward with respect to
the coupling part 76b, thereby inclining the base board 72 downward
toward the checker 64. The medal guide member 73 is also gradually
inclined downward from a rear end 73c to a front end 73d.
[0081] As shown in FIGS. 25 to 28, a base frame 77 fixed to the
chassis 41, a slider 79 supported by the base frame 77 via a pair
of guide rails 78 so as to be movable in the horizontal direction,
and a motor 80 as a driving source of the slider 79 are provided.
The rear end portion of the slider 79 is turned back downward, and
a guide plate 81 is attached to the turn-back part. In the guide
plate 81, a guide groove 81a extending in the vertical direction is
formed. On the other hand, a crank arm 82 is attached to an output
shaft 80a of the motor 80 so as to be rotatable integrally with the
output shaft 80a. A crank pin 83 is attached to the tip of the
crank arm 82. The tip of the crank pin 83 is inserted in the guide
groove 81a of the guide plate 81. Further, the guide block 70 is
disposed above the base frame 77, and the coupling part 76b of the
base 76 is coupled to the slider 79.
[0082] Therefore, when the output shaft 80a of the motor 80 is
rotated in the predetermined direction, the motion is converted by
the crank pin 83 and the guide plate 81 to reciprocating motion in
the horizontal direction of the slider 79, and the guide block 70
coupled to the slider 79 via the base 76 reciprocates in the
horizontal direction. As shown in FIG. 26, the gaps 74 between the
medal guide members 73 provided for the guide block 70 extend in
the same direction as that of the medal pass holes 64a of the
checker 64. As shown in FIG. 28, the base board 72 as the bottom of
the gap 74 is disposed above the checker 64 and, moreover, its
front side is inclined downward toward the checker 64.
[0083] With such a configuration, a medal loaded from the medal
loading device 47 and rolled along the metal guide plate 67 drops
onto the medal receiving face 73a of the guide block 70. Since the
medal receiving face 73a is formed in a semi-cylindrical shape, the
medal dropped on the medal receiving face 73a slides along the
medal receiving face 73a and is led to the gap 74. Consequently,
the direction of the medal dropped in a state where the medal is
slightly inclined toward the center side of the game board 43 from
the medal guide plate 67 is aligned in the anteroposterior
direction of the game board 43 (the extending direction of the gap
74). The medal led to the gap 74 stands and rolls down along the
baseboard 72 in a state where its direction is aligned to the same
direction as the medal pass hole 64a. Since the projection 73b is
provided at the top of the medal receiving face 73a, even if a
medal dropped from the guide plate 67 onto the medal receiving face
73a falls down sideways, because the medal comes into contact with
the projection 73b, the balance of the medal is lost, and the medal
does not become stable in a state where it lies sideways. By
collision of the medal with the projection 73b, the force of the
medal is weakened, and the medal is dropped into the gap 74 without
fail. The medal drops via the gap 74 onto the checker 64, so that
it becomes unlikely that the medal drops on the checker 64 in a
state where the medal lies sideways. The effect of adjustment of
the direction of the medal by the projection 73b has correlation
with the length of the projection 73b. For example, when the
projection 73b is short, the effect of the projection 73b is
relatively low, the frequency that the medal falls sideways onto
the checker 64 increases and, as a result, the probability that the
medal enters the checker 64 decreases.
[0084] By reciprocating the guide block 70 in the horizontal
direction by the driving mechanism 71, the position of the gap 74
and the position of the medal pass hole 64a are momentarily
switched between junction and disjunction in the anteroposterior
direction. When a medal drops onto the checker 64 at a timing the
gap 74 and the medal pass hole 64a almost coincide with each other,
that is, they are positioned in a straight line in the longitudinal
direction, the medal passes through the medal pass hole 64a. A
medal dropped onto the checker 64 at a different timing is flipped
by the checker 64 and drops onto the lower table 65. As shown in
FIG. 28, the checker 64 is provided with a guide rail 84 for
guiding the medal passed through the medal pass hole 64a into the
medal hopper.
[0085] As described above, the medal game machine of the embodiment
has the medal guiding device 63 for aligning the directions of the
medals loaded onto the game board 43 with the direction of the
medal pass holes 64a in the checker 64 before they pass through the
checker 64. Consequently, even a player who does not have enough
skill can also enjoy playing with medals passing or not passing
through the checker 64 as a game. Alternately, the base board 72
and the medal guide member 73 of the medal guiding device 63 may be
tilted in the direction opposite to that of FIG. 31, that is, they
may be formed to get lower from the front end 73d of the medal
guide member 73 forward the rear end 73c, and the checker 64 may be
disposed on the rear end 73c side of the medal guide member 73.
[0086] FIGS. 32 to 34 show the details of the medal ejecting device
44. The medal ejecting device 44 is provided to eject a large
amount of medals to the game board 43 at the time of a big hit or
the like, and has a medal tray 90, a belt conveyor 91 extended so
as to connect the right and left game boards 43 at the back of the
medal tray 90, and shooters 92 disposed between the both ends of
the belt conveyor 91 and the upper tables 62. The medal tray 90 is
provided so as to be rotatable around an axis 90a at the upper rear
end as a fulcrum, and is driven by a not-shown actuator between a
standby position extended almost horizontally forward from the axis
90a and an action position (the position shown in FIGS. 33 and 34)
in which the front end of the medal tray 90 is lifted by using the
axis 90a as a fulcrum. The actuator driving the medal tray 90 may
be an actuator such as a motor that generates rotating motion or an
actuator such as a pneumatic cylinder that generates linear motion.
In the case of the actuator that generates rotating motion, it is
sufficient to transmit the rotating motion to the periphery of the
axis 90a to turn the medal tray 90. In the case of the actuator
that generates linear motion, it is sufficient to convert the
linear motion to rotating motion of the medal tray 90 by using a
link mechanism or the like.
[0087] Medals can be ejected from the not-shown medal hopper to the
medal tray 90. When the medal tray 90 is moved from the standby
position to the action position, the medals on the medal tray 90
drop onto the belt conveyor 91. By driving the belt conveyor 91 to
the right or left direction, the medals on the belt conveyor 91 are
conveyed to one of the shooters 92, and can be ejected onto one of
the upper tables 62 via the shooter 92.
[0088] Since the belt conveyor 91 is disposed between the medal
tray 90 and the shooter 92, the shooter 92 can be made short. While
suppressing the height of the medal tray 90, the shooter 92 can be
sufficiently tilted. If the belt conveyor 91 is not used, the
shooter 92 is extended to the center area in the horizontal
direction of the medal tray 90 and means for directing the drop
direction of medals from the medal tray 90 to one of the shooters
92 is provided. In this case, when the shooter 92 is inclined
sufficiently, the overall height of the shooter 92 increases,
accordingly, the position of the medal tray 90 has to be changed
upward. However, inconveniences occur such that the overall height
of the sub unit 3 increases and the monitor 6 and the lottery
machine 7 of the main unit 2 behind the medal ejecting device 44
are hidden from sight. In contrast, in this embodiment, medals are
carried in a horizontal state to a place very close to each of the
upper tables 62 by using the belt conveyor 91, so that the shooter
92 can be made shorter and the overall height can be suppressed.
Consequently, the position of the medal tray 90 can be lowered.
(Configuration of Control System)
[0089] Next, the control system of the game machine 1 will be
described with reference to FIG. 35 and subsequent drawings. FIG.
35 is a block diagram of the control system provided for the main
unit 2. The main unit 2 has a controller 100. The controller 100 is
constructed by a computer unit having a microprocessor. To the
controller 100, a ROM 101 and a RAM 102 as main storages are
connected. To the controller 100, the monitor 6 is connected as a
display, and a ball loading mechanism 34, drum driving motor 35,
and indicator driving mechanism 36 of the lottery machine 7 are
connected as devices to be controlled. Each of the mechanisms has
one or more actuators, and the controller 100 is connected to the
actuators via drive circuits, that is not shown.
[0090] To realize a predetermined game by exchanging information
between the main unit 2 and the sub unit 3, the controller 100 of
the main unit 2 is connected to the control system of each sub unit
3. Further, to the controller 100 of the main unit 2, a
communication controller 103 is also connected. The communication
controller 103 is provided to perform information communications
via a predetermined communication line with the controller 100 of
the main unit 2 of another game machine 1 to construct a single
game system by connecting plural game machines 1. The main unit 2
may be connected to each other via the communication controllers
103 and servers, or via the communication controllers 103 without
using servers. Other than the above, various input and output
devices may be connected to the controller 100 of the main unit 2.
Another game machine 1 may be installed in the same shop or another
shop.
[0091] FIG. 36 is a block diagram of the control system provided
for the sub unit 3. The sub unit 3 also has a controller 110
constructed as a computer unit having a microprocessor. To the
controller 110, a ROM 111 and a RAM 112 as main storages are
connected. Also, to the controller 110, the monitor 60 (refer to
FIG. 19) is connected as a display. Further, to the controller 110,
various devices provided for the right and left stations 40 are
connected as input devices or devices to be controlled. For
example, to the controller 110, the operation switch 48 (refer to
FIG. 13) and a prize winning sensor 113 are connected as input
devices. The prize winning sensor 113 detects a medal passing
through the medal pass hole 64a in the checker 64 and led into the
checker 64, and outputs a predetermined detection signal. To the
controller 110, as devices to be controlled, a pusher driving motor
114 for driving the pusher 68, the motor 80 (refer to FIG. 25) for
driving the guide block 70 of the medal guiding device 63, and a
medal hopper 115 for ejecting medals in the chassis 41 are also
connected. Although FIG. 36 shows the details of only the station
40 on the left side, the station 40 on the right side has the same
configuration.
[0092] To the controller 110 of the sub unit 3, as devices to be
controlled, an actuator 116 for driving the medal tray 90 of the
medal ejecting device 44 and the belt conveyor 91 are connected.
Ejection of medals to the medal tray 90 is realized by the medal
hopper 115 here but may be realized by another medal hopper. In
this case, a medal hopper other than the medal hopper 115 is
connected as a device to be controlled corresponding to the medal
tray 90 to the controller 110.
[0093] In addition, to the controller 110 of the sub unit 3, a
communication controller 117 is also connected. The communication
controller 117 is provided so that the controller 110 performs
information communications with the controller 100 of the main unit
2 of the same game machine 1. Other than the above, various input
and output devices may be connected to the controller 110 of the
subunit 3. For example, a medal load sensor for detecting loading
of a medal from the medal loading device 47, a medal drop sensor
for detecting drop of a medal from the lower table 65, and the like
are connected to the controller 110 in order to control the medal
payout ratio.
(Outline of Game)
[0094] The contents of a game played by the game machine 1 will be
described with reference to FIGS. 37 to 40. The game machine 1 of
this embodiment provides the player with a game in relation to a
prize winning of a medal to the checker 64 besides a basic game of
a so-called pusher game which makes a medal loaded from the medal
loading device 47 and dropped to the lower table 65 pushed down
from the lower table 65 with the pusher 68. FIG. 37 shows a game
screen 200 displayed on the monitor 60 of the station 40 for such a
game. The game screen 200 includes a main game part 201, a roulette
meter 202 disposed horizontally at the bottom end of the screen
200, and a jackpot counter 203 disposed vertically at the left end
of the screen 200.
[0095] In the main game part 201, a game is executed. In the game,
three symbol bands 201a to 201c arranged in the vertical direction
are allowed to run independently of each other like reels of a slot
machine and to stop at a proper timing. Players compete for success
or failure of obtaining a predetermined winning combination of
symbols in the vertical direction or oblique direction. A game of
the main game part 201 is executed by a trigger that is the prize
winning of a medal to the checker 64. The symbols and the winning
combinations displayed in the main game part 201 may be properly
determined. As an example, they are determined as shown in FIG. 38.
Probability change denotes here an operation of increasing the
probability to succeed in obtaining a winning combination by a
predetermined level. A "center game" is a game executed by using
the main unit 2, "single" denotes that the right to play the center
game only once is given, and "triple" denotes the right to play the
center game three times in a row is given.
[0096] FIG. 39 shows a game screen 300 displayed on the monitor 6
of the main unit 2 when the center game is executed. FIG. 40 shows
a game screen 301 displayed on the monitor of a station when the
center game is executed. As obvious from FIG. 39, in the screen 300
of the center game, a map 302 having an outer route 303 and an
inner route 304 is displayed. The outer route 303 is constructed by
linking boxes 305 each having a quadrangle shape so as to form an
almost square shape. In the diagram, the boxes 305 are
distinguished from each other by adding alphabets a, b, c, . . . .
When the boxes 305 do not have to be distinguished from each other,
the boxes are indicated by reference numeral 305. The configuration
of each of the routes 303 and 304 of the map 302 is held as map
information in the ROM 101 of the main unit 2.
[0097] In the route 303 or 304, pieces 306 corresponding to the
stations 40 are displayed with station numbers (any of 1 to 6). The
game screen 301 of FIG. 40 is an enlarged portion of the game
screen 300, in which the piece 306 corresponding to the station 40
in which the screen 301 is displayed is positioned.
[0098] When the right to play the center game is given in the game
in the station 40, any of the numbers 1 to 8 is chosen by using the
lottery machine 7 for the station, and the piece 306 moves in the
predetermined direction on the route 303 or 304 by the number of
boxes just equal to the number chosen by the lottery. In each of
the boxes 305, a reward given in the center game is written. When
the piece 306 stops in a box, the reward written in the box is
given to the player who played the center game.
[0099] For example, when the piece 306 stops in a box 305a in which
the number such as "30" or "50" is written, the player gets medals
of the number equal to the number written in the box. The outer
route 303 includes a box 305b in which "SJP chance" is written
(hereinbelow, called SJP box). When the piece 306 stops in the SJP
box 305b, the right to challenge super jackpot is given. In this
case, a lottery for determining whether the player wins the super
jackpot or not is executed by using the lottery machine 7. If the
player wins the super jackpot, the player gets medals of the number
displayed in an SJP display part 307 (hereinbelow, called SJP
number) adjacent to the outside of the SJP box 305b. When the piece
306 passes the SJP box 305b, the SJP number is increased by a
predetermined number.
[0100] On the other hand, the inner route 304 includes a box 305c
described as "BB chance" (hereinbelow, called BB box). When the
piece 306 stops here, the player gets the right to challenge a big
bonus. In this case, the lottery for determining whether the player
wins the big bonus or not is executed by using the lottery machine
7. If the player wins the big bonus, the player gets medals of the
number displayed in a BB display part 308 (hereinbelow, called BB
number) disposed in the center area of the inner route 304. When
the piece 306 passes through the BB box 305c, the BB number is
increased by a predetermined number.
[0101] At the four corners of each of the routes 303 and 304, warp
boxes 305d written as "GO" are disposed. When the piece 306 stops
in the warp box 305d, the piece 306 moves between the outer route
303 and the inner route 304. As understood by comparing numerical
values indicated in the boxes 305a between the routes 303 and 304,
the player can get higher points in the inner route 304 than the
outer route 303. Although bonus boxes 305e, 305f, . . . are
properly provided in the routes 303 and 304 in addition to the
above, they will not be described since they are not the gist of
the present invention.
[0102] When plural game machines 1 are connected to each other to
construct a single game system, the inner route 304 is shared by
the game machines 1. That is, the information of the configuration
of the inner route 304 stored in the ROM 101 in each game machine 1
in the single game system is the same. The game machines 1 share
the positions of the pieces 306 disposed on the inner route 304 and
the BB numbers. The information is stored as information in the RAM
102 of each game machine 1. The information is properly exchanged
among the game machines 1 to maintain consistency.
[0103] In the inner route 304, a piece 309 of another game machine
1 is also displayed. When the piece 309 stops in the BB box 305c,
the right to challenge the big bonus is given to the station 40 of
the game machine 1 corresponding to the piece 309. When the piece
309 passes through the BB box 305c, the BB number is added by a
predetermined number in all of the game machines 1 in the same game
system. That is, the BB number has the characteristic of so-called
progressive bonus which is shared among the plural game machines
1.
[0104] By sharing part of the map 302 among the plural game
machines 1 and setting the correlation among the game machines 1
also with respect to points of the game in the shared part, the
player has to pay attention not only to the other player of the
same game machine 1 but also the players of the other game machines
1, so that enjoyment of the game increases. Since the plural game
machines 1 accumulate common points, larger points can be
accumulated as compared with the case of accumulating points of the
game by a single game machine. Thereby, the enjoyment of the game
can be also increased.
(Control Procedure)
[0105] When a station control routine starts, first, in step S101,
the controller 110 executes the lottery about a combination of
symbols to be displayed on a main play part 201 in the game screen
200 by using random numbers and controls the display state in the
main play part 201 so that the result of the lottery is displayed.
Concretely, the controllers 110 makes the symbol bands 201a to 201c
run and controls the display state of each of the symbol bands 201a
to 201c so that the combination of symbols determined by the
lottery is obtained.
[0106] After that, a combination for probability change start
(except for "777") is obtained or not is determined in step S102.
If the combination is obtained, a probability change flag is set to
"1" in step S103, and the process goes to step S106. On the other
hand, when the combination is not obtained, the process goes to
step S104 to determine whether a combination for probability change
end is obtained or not. If the combination is obtained, the
controller 110 resets the probability change flag to "0", and the
process goes to step S106. The probability change flag is
considered in the lottery in step S101. When the flag is set to
"1", the probability to obtain the winning combination (the
combinations shown in FIG. 38) is increased as compared with the
case where the flag is reset to "0".
[0107] In step S106, the medal hopper 115 is driven to eject medals
of the number corresponding to the combination obtained in the
lottery from the medal ejection port 61 onto the upper table 62. At
this time, dramatic presentation may be performed in such a manner
that players can feel as if medals fell by displaying an image of
dropping medals on the monitor 6 in synchronization with ejecting
medals from the medal ejection port 61.
[0108] After ejection of medals, the process goes to step S107 to
add "1" to the value of a JP step stored in the RAM 112. The value
of the JP step is equal to the number of light-on of the jackpot
counter 203 in the game screen 200. Each time the value of the RAM
112 is updated, in accordance with that, the number of light-on of
the jackpot counter 203 is also updated. In the following step
S108, it is determined whether the JP step reaches the
predetermined maximum value (7 in this case) or not. If it reaches
the maximum value, it means the JP is obtained and the process goes
to step S109. The upper table 62 is driven to move from the
horizontal position to the action position, and again to the
horizontal position to drop all medals accumulated on the upper
table 62 onto the medal guiding device 63, thereby jackpot medals
are ejected toward the lower table 65. At this time, medals may be
ejected also from the medal ejection port 61. After that, in step
110, the JP step on the RAM 112 is reset to the initial value "0",
and the station control routine is finished.
[0109] On the other hand, when the condition in step S104 is not
satisfied, the process goes to step S111 and it is determined
whether the combination for single-center-game (refer to FIG. 38)
is obtained or not. If the combination is obtained, the process
goes to step S112 to notify that the combination for
single-center-game is obtained to the controller 100 of the main
unit 2. After that, the process goes to step S106 to eject medals
corresponding to the combination for single-center-game.
[0110] When the condition in step S111 is not satisfied, the
process goes to step S113 to determine whether a combination for
the triple-center-game is obtained or not. If the combination is
obtained, the process goes to step S114 to drive the upper table 62
for moving from the horizontal position to the action position, and
again to the horizontal position. In the following step S115, the
fact that the combination for triple-center-game is obtained is
notified to the controller 100 of the main unit 2. After that, the
process goes to step S103 to set the probability change flag to "1"
ant goes to step S106 to eject medals corresponding to the
combination for triple-center-game.
[0111] If the combination for triple-center-game is not obtained in
step S113, the process goes to step S116 to determine whether or
not roulette symbols (symbols in the second line from the bottom in
FIG. 38) exist in the main play part 201 after the stop of symbol
bands 201a to 201c. If the symbols exist, the process goes to step
S117 to add "1" to the value of the roulette meter stored in the
RAM 112. The value of the roulette meter is equal to the number of
light-on of the roulette meter 202 in the game screen 200. Each
time the value in the RAM 112 is updated, in accordance with that,
the number of light-on of the roulette meter 202 is also updated.
In the following step S118, it is determined whether the roulette
meter value reaches the predetermined maximum value (25 in this
case) or not. If the value reaches the maximum value, the process
goes to step S119 to notify the controller 100 of the main unit 2
of the fact that the combination for single-center-game is
obtained. After that, in step S120, the roulette meter value in the
RAM 112 is reset to the initial value of "0" and the station
control routine is finished.
[0112] When it is determined in step S116 that roulette symbols do
not exist or when it is determined in step S118 that the meter
value is not the maximum value, the controller 110 skips the
subsequent processes and finishes the station control routine.
[0113] Next, the processes of the controller 100 of the main unit 2
will be described. FIGS. 42 and 43 show a center game control
routine executed by the controller 100 of the main unit 2 to
realize a center game. The routine is executed for the station 40
which obtains the combination for the single-center-game or
triple-center-game when the fact that the combination for the
single-center-game or triple-center-game is obtained has been
notified from the controller 110 of any one of the sub units 3.
That is, the following process is executed on the only station 40
which obtains the combination for the single-center-game or
triple-center-game, as long as not specified.
[0114] When the center game control routine starts, first, in step
S200, the controller 100 determines whether the combination for
single-center-game has been notified or not. When the combination
has been notified, the process goes to step S201 to set the initial
value of "1" to a variable N for determining the number of games.
When the combination has not been notified (that is, when the
combination for triple-center-game has been notified), the process
goes to step S202 to set the initial value of "3" to the variable
N. After the variable N is set, the process goes to step S203 to
determine one of the numerical values 1 to 8 by roulette lottery,
that is, lottery using the lottery machine 7. The controller 100
updates the position information of the piece 306 stored in the RAM
102 so that the position of the piece 306 on the map 302 is
advanced by the number of boxes equal to the obtained numerical
value. The information of the position of the piece 306 is held in
the RAM 102 in association with information for identifying the
station 40. The position information updated at this time relates
to the piece 306 corresponding to the station 40 which has obtained
the combination for single-center-game or triple-center-game. The
display on the monitor 6 is also updated in correspondence with
updating of the piece position information.
[0115] In the following step S204, it is determined whether the
piece 306 has passed the SJP box 305b or not. If the piece 306 has
passed it, the SJP number of the SJP display 307 adjacent to the
SJP box 305b is increased by a predetermined number in step S205.
After that, the process goes to step S208. On the other hand, when
the piece 306 has not passed the SJP box 305b in step S204, the
process goes to step S206 to determine whether the piece 306 has
passed through the BB box 305c or not. When the piece 306 has
passed the BB box 305c, the process goes to step S207 to increase
the BB number by a predetermined number. Since the BB number is
shared by other game machines 1 constructing the same game system,
increase in the BB number is also notified to the controllers 100
of the game machines 1. After such processes, the process goes to
step S208. If it is determined that the piece 306 has not passed in
step S206, the controller 100 skips step S207 and the process goes
to step S208.
[0116] In step S208, the kind of a box (stop box) corresponding to
the position of the piece updated in step S203 is determined. In
the subsequent step S209, the controller 100 determines whether the
piece 306 has stopped in the SJP box 305b or not. If the piece 306
has stopped, the process goes to step S210 to perform roulette
lottery for super jackpot. The roulette lottery in this case is
performed by using, for example, one of the eight areas shown on
the drum 31 of the lottery machine 7 as a super jackpot (SJP)
winning box. Obviously, the lottery may be performed by using other
means. After the roulette (drum 31) stops, the processing goes to
step S212 to determine whether the player has won the super jackpot
or not. If the player has won, the process goes to step S216. If
not won, the process goes to step S220 in FIG. 43. In step S220,
medals of the number according to the numerical value obtained by
the roulette lottery in step S210 or S213 is set to the number of
medals the player got.
[0117] On the other hand, when in step S209 in FIG. 42 it is
determined that the piece 306 has not stopped in the SJP box 305b,
the process goes to step S212 to determine whether the piece 306
has stopped in the BB box 305c or not. If the piece 306 has
stopped, the process goes to step S213 to perform roulette lottery
on a big bonus. The roulette lottery in this case is also performed
by using, for example, one of the eight areas shown on the drum 31
of the lottery machine 7 as a big bonus (BB) winning box.
Obviously, the lottery may be performed by using other means. After
the roulette (drum 31) stops, the process goes to step S214 to
determine whether the player has won the big bonus or not. If the
player has won, the process goes to step S215 to notify the other
game machines 1 included in the same game system of winning of the
big bonus, and goes to step S216. The processes in steps S204 to
S209 and S212 can be performed immediately after the result of the
roulette lottery is obtained in step S203. It is not unnecessary to
wait until the display on the monitor 6 is updated in accordance
with the result obtained in step S203.
[0118] In step S216, medals of the number according to SJP or BB
are ejected. The medals are ejected to the medal tray 90 of the
medal ejecting device 44. Therefore, the controller 100 instructs
the controller 110 of the sub unit 3 to eject medals. In response
to the instruction, the controller 110 waits for completion of
ejection of medals to the medal tray 90 and drives the medal tray
90 to the action position. After the medals drop onto the belt
conveyor 91, the controller 110 drives the belt conveyor 91 toward
the station 40 which has won SJP or BB, thereby the medals ejected
to the medal tray 90 are ejected onto the upper table 62 of the
station 40.
[0119] After the ejection of medals for the SJP or BB, the process
goes to step S217 to reset the SJP number or BB number stored in
the RAM 102 to the initial value, and finish the center game
control routine. When it is determined in step S212 that the piece
306 has not stopped in the BB box 305c, the process goes to step
S221 in FIG. 43.
[0120] In step S221 in FIG. 43, the controller 100 determines
whether the piece 306 has stopped in the warp box 305d or not. If
the piece 306 has not stopped, the process goes to step S222 to
determine whether the piece 306 has stopped in any of the other
bonus boxes 305e, 305f, . . . or not. When the piece 306 stops in
the regular box 305a, step S222 is determined as NO. In this case,
the process goes to step S223 to set the numerical value described
in the box 305a in which the piece 306 stops as the obtained
number. On the other hand, when the condition in step S222 is
determined as YES, the process goes to step S224 to execute a
process according to a prize winning assigned to the bonus box 305e
. . . .
[0121] After the obtained number is set in step S220 or S223, the
process goes to step S225 to eject medals of the number according
to the obtained number. Ejection of medals in this case may be also
performed by using the medal electing device 44. When the number is
small, medals may be ejected from the medal ejection port 61. When
the piece 306 stops in the warp box 305d in step S221, the process
goes to step S227 to move the piece 306 between the warp box 305d
in the outer route 303 and the warp box 305d in the inner route
304. The condition of movement from the outer route 303 to the
inner route 304 and the condition of movement from the inner route
304 to the outer route 303 may be different from each other. For
example, the movement from the outer route 303 to the inner route
304 may be more regulated as compared with the movement from the
inner route 304 to the outer route 303.
[0122] After the processes in step S224, S225, or S227, the process
goes to step S226 to notify the other game machines 1 of the
updated stop position of the piece 306. The notification may be
sent regarding only the piece 306 positioned in the inner route
304. After the notification of the stop position, the process goes
to step S228 to determine whether the variable N is 1 or not. If
the variable N is not 1, the process goes to step S229 to subtract
1 from the variable N and, after that, return to step S203 in FIG.
42. If the variable N is 1 in step S228, the controller 100
finishes the center game control routine.
[0123] FIG. 44 shows a game information update control routine
executed by the controller 100 so that the BB number and the
positions of the pieces 306 and 309 on the inner route 304 are
shared with the other game machines 1. The process is repeatedly
executed in proper cycles by the controller 100. In the game
information update control routine, first, in step S250, the
controller 100 determines whether addition of the BB number has
been notified from another game machine 1 or not. If the addition
has been notified, the process goes step S251 to update the BB
number held in the RAM 102 to the value obtained by increasing the
BB number by a predetermined number. If the addition has not been
notified, the controller 100 skips step S251. In the following step
S252, the controller 100 determines whether winning of the BB has
been notified from another game machine 1 or not. If it has been
notified, the process goes to step S253 to reset the BB number held
in the RAM 102 to the initial value. If it has not been notified,
the controller 100 skips step S253.
[0124] In the following step S254, the controller 100 determines
whether the stop position of the piece 306 has been notified from
another game machine 1 or not. If it has been notified, the process
goes to step S255 to update the position information of the piece
309 on the inner route 304 held in the RAM 102 in accordance with
the notified information. If it has not been notified, the
controller 100 skips step S255. In the following step S256, the
controller 100 updates the BB number and the information in the map
302 in accordance with the latest information held in the RAM 102.
After that, the game information updating control routine is
finished.
[0125] By the proper repeat execution of the routine of FIG. 44,
the BB number and the piece position information on the inner route
304 held in the RAM 102 of each game machine 1 can be maintained in
the same state.
[0126] The present invention is not limited to the foregoing
embodiments but may be carried out in various modes. For example,
the protrusion portion 57 may not be provided continuously through
the overall length in the width direction of the medal tray 50. Two
or more protrusion portions may be provided at an interval in the
width direction of the medal tray. The protrusion portion is not
limited to the tapered shape but may have a rectangular or
semi-circular shape in cross section.
