Description
This invention relates to game machines which are adapted to form
on a screen images of a road and motor vehicles running on the
road.
The known game machines of the type described include a game
machine of the driving simulator type wherein a road is graphically
represented on a rotary drum and projected onto a screen. No images
of motor vehicles are formed on the screen in this type of game
machine, so that the pictures on the screen are monotonous and
without variety.
Another type of game machine known in the art comprises a plurality
of transparent discs carrying the image of a road and the images of
motor vehicles respectively and mounted in parallel relation for
rotation relative to one another, a light source for projecting the
images carried by the discs onto a screen, and drive means for
rotating the discs. In this type of game machine, the light emitted
by the light source is directed normal to and passes through each
of the discs carrying the road and motor vehicle images
respectively and is projected onto the screen after being reflected
by a reflector. As a result, the motor vehicle images on the screen
are two-dimensional and the picture on the screen lacks
three-dimensional effect. Because of this, the player of the game
can have no sense of himself driving a car on the spot and
consequently his interest in the game tends to be reduced.
Accordingly, an object of this invention is to provide a game
machine of the type described hereinabove which gives an illusory
three-dimensional effect to the images of motor vehicles running
along the road on the screen so as to thereby enhance the interest
of the player in the game.
Another objects of the invention is to provide a game machine of
the type described hereinabove wherein the motor vehicles running
along the road on the screen have relative speeds, so that it is
possible to produce on the screen the scene of one motor vehicle
passing and being passed by the other motor vehicle ahead.
Another object of the invention is to provide a game machine of the
type described hereinabove wherein the banking phenomenon of motor
vehicles can be produced on the screen when the motor vehicles run
along curved turns of the road whereby the player can have the
sense of actually driving a car on the spot.
Additional objects as well as features and advantages of the
invention will become evident from the description set forth
hereinafter when considered in conjunction with the accompanying
drawings, in which:
FIG. 1 is a perspective view of an embodiment of the game machine
according to this invention showing its external appearance;
FIG. 2 is a side view of the game machine of this invention showing
its interior;
FIG. 3 is a fragmentary enlarged sectional view of discs carrying
the images of a road and three-dimensional motor vehicle
models;
FIG. 4 is a view in explanation of drive means for the discs and an
oscillation mechanism for a unit consisting of the discs and their
drive means;
FIG. 5 is a side view of the device of FIG. 4 showing a light
source supporter moving mechanism;
FIG. 6 is a plan view of the light source supporter moving
mechanism of FIG. 5;
FIG. 7 is plan views showing the discs;
FIG. 8 is a view in explanation of a speed control device;
FIG. 9 is a sectional view taken along the line A-B of FIG. 8;
and
FIGS. 10 and 11 are views in explanation of the images of motor
vehicle models running along the road on the screen when the
vehicles are running normally and when they are banking.
In FIG. 1, there is disclosed a game machine of this invention
generally designated 1 which is formed on its front with a
simulated driving room provided with a steering wheel 2, panel
board 3, wind shield 4 and accelerator 5. 6 is a slit for inserting
a coin therethrough.
In FIG. 2, mounted on the game machine 1 is drive means 7 to which
three discs 8, 9 and 10 are connected for rotation at relative
speeds different from one another. Disposed above said discs is a
light source 11 from which light is emitted so as to project on a
screen 12 images of three-dimensional motor vehicle models carried
by the discs 8 and 9 respectively and the image of a road
pictorially represented on the disc 10 in such a manner that these
images are superimposed one over another on the screen. It is thus
possible to see from outside through the wind shield 4 the images
of road and motor vehicles on the screen 12.
The drive means 7 includes an electric motor 13 for operating the
discs 8 and 9 carrying the three-dimensional motor vehicle models
which drives the discs 8 and 9 through a gearing 14 so that the
discs 8 and 9 can rotate at different speeds. In addition, a
differential gearing may be mounted between the discs 8 and 9 so as
to periodically vary the difference between the rates of rotation
of the two discs. By manipulating the steering wheel 2, it is
possible to move, through a pinion 15, rack 16 and wire 17, the
light source 11 relative to the discs, so that the position of the
road on the screen 12 can be varied to make the player feel as if
he were operating the steering wheel of his car to cause the car to
keep to the right and left sides of the road as desired. The
detailed description of this mechanism is subsequently to be
described. 20 is a continuous speed control device according to
this invention which is rendered operative as the accelerator 5 is
depressed. The device is connected to the accelerator 5 by a wire
22 trained about a wheel 21 and to a drive motor for operating,
through conductors 23, the disc on which the road is pictorially
represented, so that when the accelerator 5 is depressed the
continuous speed control device 20 is rendered operative to control
the rate of revolution of said drive motor. The details of the
speed control device is subsequently to be described.
The three-dimensional motor vehicle models according to this
invention are disposed between the discs 8 and 9 which will be
described with reference to FIG. 3.
Arranged in a space between the discs 8 and 9 are three-dimensional
motor vehicle models 18 and 19 made of a transparent or
semi-transparent material. A number of models 18 are fixed at their
upper sides to the disc 8 in positions disposed on the
circumference of at least one imaginary circle on the disc 8, with
a clearance being maintained between the undersides of wheels
thereof and the upper side of the disc 9. A number of models 19 are
fixed at their wheels to the disc 9 in positions disposed on the
circumference of at least one imaginary circle on the disc 9 which
imaginary circle is concentric with and smaller than said imaginary
circle on the disc 8, with a clearance being maintained between the
upper sides of the models 19 and the underside of the disc 8. This
arrangement permits the three-dimensional motor vehicle models 18
and 19 to run, when the discs 8 and 9 are rotated at rates
differing from each other, without being brought into contact with
the discs 9 and 8 opposed to the models 18 and 19. It is possible,
of course, to mount the three-dimensional models 18 on the upper
side of the disc 9 and the three-dimensional models 19 on the
underside of the disc 8.
Preferably, each of the three-dimensional models 18 and 19 made of
a transparent or semi-transparent material is colored by applying
transparent or semi-transparent ink thereto. Alternatively, the
material itself may be colored with a dyestuff and fabricated into
parts to be connected together to provide a motor vehicle
model.
The light from the light source 11 is transmitted through the
three-dimensional motor vehicle models 18 and 19 to project images
thereof on the screen 12. The present invention permits to give
three-dimensional effect to the projected images, with changes in
the three-dimensional shape of the images of motor vehicle models
on the screen corresponding to changes in the appearance of motor
vehicles passing by when one actually drives an automobile on the
highway. This has the effect of making the player of this game
machine feel as if he were actually driving an automobile. In order
that the images of motor vehicles on the screen may resemble real
motor vehicles in shape, the three-dimensional models 18 and 19 are
preferred to be deformed in shape rather than formed true to actual
shape on a reduced scale so as to prevent undue enlargement or
reduction in size of portions of the three-dimensional models which
would otherwise be caused by the distance between the light source
11 and models 18, 19 and between the models 18, 19 and screen 12 as
well as their relative positions.
In FIG. 4, the electric motor 13 for driving the discs carrying the
three-dimensional motor vehicle models is held on the drive means
7. The motor 13 has a drive shaft 24 which drives, through a
reduction gearing 25, an intermediate shaft 26 which drives a shaft
29 for rotating the upper disc 8 and a hollow shaft 30 for rotating
the center disc 9 through reduction gearings 27 and 28
respectively. Slidably mounted on the hollow shaft 30 is a hollow
shaft 31 for rotating the lower disc 10 which hollow shaft is
driven by an oscillation drive motor 32 shown in FIG. 5 through
gears 33 and 34 in meshing engagement with each other and a gear 35
fixed to the hollow shaft 31 to mesh with the gear 34. Fixed to a
shaft 36 of the gear 34 is a bevel gear 37 which is in meshing
engagement with another bevel gear 39 fixed to one end of a shaft
38 disposed normal to the shaft 36. The shaft 38 is fixed, at the
other end, to one end of a shorter arm 40 of a double crank
mechanism which is pivotally connected, at the other end, to a
longer arm 41 which is pivotally connected to the machine frame by
a pin 42 disposed on the side of the longer arm which is opposite
to the side on which the shorter arm is pivotally connected. The
drive means 7 is housed in a casing which is oscillatably supported
by support bars 43 pivoted at 44 to the machine frame.
In FIG. 5, a support 45 for the light source 11 is mounted for
movement relative to each of the discs as subsequently to be
described. A lever 46 (FIG. 6) carrying the support 45 has mounted
on one side thereof a tension spring 47 which is connected at the
other end to the drive means casing or a frame secured thereto and
on the other side a connecting rod 48 which is attached at its
other end to one arm of a double arm lever 50 pivoted at 49 to the
drive means casing or frame. Connected to the other arm of the
double arm lever 50 is one end of the wire 17 shown in FIG. 2 which
is attached at the other end to one end of the rack 16 shown in
FIG. 2. In FIG. 2, the rack 16 is maintained in engagement with the
pinion 15 mounted at the end of a shaft of the steering wheel 2, so
that the rack 16 moves in a direction normal to the plane of FIG. 2
as the steering wheel 2 is manipulated.
As shown in FIG. 6, the light source supporter 45 which is mounted
on the lever 46 pivotally connected to drive means casing or frame
at 51 is capable of adjusting its position on the lever 46 and also
of being fixed in any position as desired. The end of the
connecting rod 48 mounted on the lever 46 is also capable of
adjusting its position on the lever 46 and also of being fixed in
any position as desired.
If the steering wheel 2 shown in FIG. 2 is munipulated to move the
wire 17, through the pinion 15 and rack 16, in a direction in which
it causes the double arm lever 50 to move in pivotal motion in an
anticlockwise direction, then the lever 46 is moved, through the
connecting rod 48, in pivotal motion in a clockwise direction
against the biasing force of the spring 47 in FIG. 6. This causes
the light source supporter 45 to move to the left in FIG. 6. It
will be readily understood that if the steering wheel 2 is
manipulated in the opposite direction so as to move the wire 17 in
a direction in which it causes the double arm lever 50 to move in
pivotal motion in a clockwise direction, the light source supporter
45 will move to the right in FIG. 6.
In FIG. 7, the three-dimensional models 18 and 19 of motor vehicles
or racing cars are mounted on the upper disc 8 and center disc 9
respectively to be disposed on ceoncentric imaginary circles
thereon, and a road 52 is drawn on an imaginary circle on the lower
disc 10 which is concentric with the imaginary circles on the discs
8 and 9. The three-dimensional models 18 mounted on the upper disc
8 and the three-dimensional models 19 mounted on the center disc 9
are arranged such that the former 18 are disposed in positions
corresponding to the outer side of the road 52 and the latter 19
are disposed in positions corresponding to the inner side of the
road 52. As shown in FIGS. 3, 4 and 5, a wall 53 disposed axially
of the shafts supporting the discs 8, 9 and 10 is provided on the
peripheral edge of the lower disc 10. The upper end of the wall 53
can be shaped like mountain summits so that the images of mountain
disposed at a distance can be formed on the screen 12.
In FIGS. 8 and 9, the speed control device 20 has a reflecting
surface 56 formed on one inner side wall of a casing 55 which is
closed and sealed so as to be impermeable to light. A light source
57 is provided near said reflecting surface. Pivotally mounted on a
shaft 58 in the casing 55 is a pivotal member 59 which carries at
its forward end a pivotal head 60 which houses therein a
photoelectric transducer element. The photoelectric transducer
element has a light receiving surface which faces downwardly. The
conductors 23 (not shown in FIG. 8, but see FIG. 3 connected to the
photoelectric transducer element are passed through the pivotal
member 59 to be led out of the casing 55, thence to the oscillation
drive motor 32 of the drive means 7.
A tension spring 62 connected at one end to the casing 55 is
connected at the other end to the pivotal member 59. The wire 22 is
also connected, at one end, to the pivotal member 59 in such a
manner that the position in which the wire 22 is connected can be
adjusted by means of a screw 64 and a slit 65 formed in the pivotal
member 59 with its major dimension being disposed axially of the
pivotal member. The wire extends through one side wall of the
casing to be led to the outside and connected, at the other end, to
the accelerator 5 through the wheel 21 as shown in FIG. 2. A
linkage may be used for connecting the pivotal member 59 to the
accelerator 5 instead of the wire 22. The pivotal head 60 is
mounted on the pivotal member 59 by a screw 66 received in a slot
formed in the pivotal member with its major dimension being
disposed axially of the member so that the position of the former
on the latter can be adjusted as desired by the screw and slot
arrangement. This permits one to vary the distance between the
light receiving surface of the photoelectric transducer element and
the reflecting surface 56 of the casing 55 as desired.
When the pivotal head 60 is disposed in a position shown in solid
lines in FIG. 8, for example, the light emitted by the light source
57 and reflected by the reflecting surface 56 is incident upon the
light receiving surface of the photoelectric transducer element
mounted in the pivotal head 60. When this is the case, the volume
of light reflected by the reflecting surface and incident upon the
light receiving surface is relatively great, because the light
receiving surface and the reflecting surface are substantially
parallel to each other and the distance between the two surfaces
and the distance between the light source 57 and the portion of the
reflecting surface corresponding to the light receiving surface are
small. If the accelerator 5 is operated to loosen the wire 17 at
this time, the pivotal member 59 and the pivotal head 60 mounted
thereon are moved, in pivotal motion, by the biasing force of the
spring 62 in a clockwise direction about the shaft 58 to, say, a
position shown in dot-and-dash lines. This causes a change in the
relative positions of the light receiving surface and reflecting
surface and the angular displacement of the light receiving surface
from the reflecting surface as well as an increase in the distance
between the light source 57 and the portion of the reflecting
surface corresponding to the light receiving surface. Accordingly,
the volume of light incident on the light receiving surface of the
photoelectric transducer element is reduced. The volume of light
can be varied continuously by the pivotal movement of the pivotal
head 60. The position in which the pivotal head 60 is stopped in
its pivotal movement can be selected as desired by suitably
manipulating the wire 22.
In operation, if the proper coin is inserted into the machine
through coin slot 6, the main switch of the machine will be turned
on to supply power to the drive motor 13 and light source 11,
causing the upper and center discs 8 and 9 to rotate. Since the
lower disc 10 remains stationary, the three-dimensional motor
vehicle models carried by the upper and center discs are projected
onto the screen 12 to form thereon images of the motor vehicles
running on the stationary road (FIG. 10). The rates of revolution
of the discs 8 and 9 differing from each other, the motor vehicles
running on the inner side of the curved turns of the road on the
screen and the motor vehicles running on the outer side thereof
differ from one another in speed. If the disc 8 is caused to rotate
in one direction and the disc 9 is caused to rotate in a direction
opposite to the one direction, then it is possible to form on the
screen images of three-dimensional motor vehicles running in
opposite directions on the same road on the screen.
If the pedal 5 shown in FIGS. 1 and 2 is depressed, then a switch
(not shown) is turned on to actuate the oscillation drive motor 32
shown in FIG. 5. If this is the case, the position of the pivotal
member 59 and hence the position of the pivotal head 60 shown in
FIG. 8 are adjusted through the wire 22 trained about the wheel 21.
The oscillation drive motor 32 has its rate of revolution adjusted
in accordance with the position of the pivotal head 60 having a
built-in photoelectric transducer element as aforementioned.
Power transmitted through the gears 33, 34 and 35 and hollow shaft
31 causes the lower disc 10 to rotate, and at the same time power
is transmitted to the double crank mechanism through the bevel gear
37 mounted on shaft 37, the bevel gear 39 in meshing engagement
with said bevel gear 37, and shaft 38. Thus, the unit consisting of
the discs 8, 9 and 10 and drive means 7 moves in pivotal motion
about the pivot 44 shown in FIG. 4. By suitably selecting the
mounting position of the longer arm 41 of the double crank
mechanism 40 and 41, it is possible to cause the unit to move in
pivotal motion only in one direction from its neutral position. For
example, if the longer arm 41 is mounted as shown in FIG. 5, then
the unit moves in pivotal motion only to the right. By this
arrangement, it is possible to cause the road and skyline to tilt
periodically and show a change of the scene as will be apparent by
comparing FIG. 10 with FIG. 11. This makes the player feel as if
the motor vehicle he is driving is tilted. As the discs 8, 9 and 10
tilt, the images of motor vehicle models, road and background
formed on the screen 12 will naturally tilt, so that the
arrangement gives a realistic banking effect to the screen. In
causing the motor vehicle models to bank, it is possible to cause
the unit to move in pivotal motion without causing the lower disc
10 to rotate. This can be accomplished simply by releasing the
gears 34 and 35 from meshing engagement with each other. It is also
possible to cause the lower disc 10 to be rotated by the motor 13
at all times. To this end, a clutch adapted to be controlled by the
accelerator 5 may be mounted on a shaft mounted for driving the
disc 10.
If the player manipulates the steering wheel 2, the position of the
road on the screen 12 can be varied because the light source 11
moves relative to the discs as aforementioned. This makes the
player feel as if the motor vehicle he is driving were steered to
right and left. It is possible to make the whole or a part of the
motor vehicle driven by the player appear on the screen.
