[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine, such as a pachinko machine, which discharges a prize ball out of the machine in response to winning of a game ball.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 15, a gaming machine 300, such as a pachinko machine or an arrangement ball type gaming machine (alepachi), which uses a steel game ball, has a substantially rectangular main body frame 302 inside a game machine. It accommodates the board 304, and the main frame 3
A front frame 308 that is opened and closed by a pair of hinges 306a and 306b is attached to the 02, and an upper tray 310 is attached to the front frame 308 so that the upper tray 310 can be opened and closed.

A plurality of gaming machines 300 are juxtaposed on a gaming machine installation island (hereinafter simply referred to as an island) via a main body frame 302,
A ball lending machine is installed between the adjacent gaming machines 300. As shown in FIG. 16, the conventional hinge 306a has a body frame 3
The rotation metal fitting 324 is connected to the protruding portion 320a of the support metal fitting 320 fixed to the No. 02 via the shaft pin 322, and the front frame 308 is fixed to the rotation metal fitting 324.
With this structure, as shown in FIG. 16B, the front frame 308 is
When is opened, the front frame 308 is separated from the main body frame 302 by the amount of the protrusion of the shaft pin 322 from the main body frame 302. For example, the front frame opened to the adjacent gaming machine 300 or ball lending machine. The interference with 308 and the upper tray 310 was prevented.

[0004]

However, since the conventional hinge protrudes to the front side of the gaming machine, that is, to the player side, the appearance of the gaming machine may be impaired. Also, depending on the game state, such as when the so-called big hit state, a large number of game balls may be paid out as prize balls in a short time, and it is desirable to be able to store a larger number of game balls in the upper and lower trays. Was there. For example, if you try to increase the volume of the saucer by projecting the saucer forward (on the side of the player), the adjacent game machine or ball lending machine will interfere with the saucer when the front frame is opened. It was difficult to deal with such requests.

[0005]

As a means for solving the above-mentioned problems, the hinge of the first aspect of the present invention includes a fixed side member and a movable side member which are interposed between the fixed side member and the movable side member. In a hinge that is connected so as to be capable of relative swinging, a first swinging member that is fixed to a fixed member and a first swinging member that is pivotally supported by the fixing piece through a first end pin and swings around the first end pin. A second piece pivotally supported by the fixed piece via a moving piece and a base end pin substantially parallel to the first end pin and swinging about the base end pin.
And a second swinging piece connected to the first swinging piece via an intermediate pin parallel to the base end pin and connected to the first swinging piece via a second end pin substantially parallel to the first end pin. And a first connecting pin that is parallel to the first end pin and that is parallel to the first end pin and that is parallel to the first end pin according to the swing of the first swing piece and the second swing piece. And a parallel movement piece that is relatively swingably coupled to the movable side member, and one end is relatively swingably coupled to the movable side member about a second connection pin that is substantially parallel to the first connection pin. In addition, the other end is arranged outside the straight line connecting the base end pin and the intermediate pin of the second swinging piece and at a position farther from the base end pin than the intermediate pin, and is substantially parallel to the base end pin and the intermediate pin. A third swinging member swingably connected to the parallel moving piece through a tip pin. By providing a single, and the movable member is swingable said first connection pin while close to or detached to the fixed member in response to the translation of the translation member as an axis.

A gaming machine according to a second aspect of the present invention includes a substantially rectangular main body frame that supports the gaming board, a glass plate that covers the front side of the gaming board and forms a gaming area between the gaming board and the gaming board, It is equipped with a front frame that is openably and closably attached to the main body frame and supports the glass plate, and a set number of game balls are awarded when a predetermined winning state occurs due to the behavior of the game balls shot in the game area. In the gaming machine ejected as, the main body frame and the front frame are connected via the hinge of the first invention.

[0007]

In the hinge having the above structure, the operation will be described when the fixed member is relatively fixed and the movable member is opened and closed. First, in order to shift from the closed state to the open state, a force in the direction of shifting from the closed state to the open state is applied to the movable member. When the movable side member starts to swing due to this force, the parallel movement piece connected to the movable side member via the first connecting pin and the third moving piece connected to the movable side member via the second connecting pin. The swinging piece is pulled by the movable side member and is displaced in the direction toward the movable side member.

The first swing piece connected to the parallel movement piece via the second end pin and the second swing piece connected to the parallel movement piece via the intermediate pin move in parallel. It is pulled by one piece and swingably displaced about the first end pin and the base end pin, respectively. At this time, in the second swing piece, the displacement amount of the tip pin farther from the base pin is larger than the displacement amount of the intermediate pin close to the base pin. Therefore, the displacement amount of the third swing piece connected to the second swing piece via the tip pin is equal to the displacement of the parallel movement piece connected to the second swing piece via the intermediate pin. Will be larger than the quantity. Therefore, the movable member is largely displaced so that the second connecting pin side is pushed out by the third swinging piece, and is swingably displaced about the first connecting pin. At the same time, the movable side member moves in the direction in which it separates from the fixed side member in response to the parallel movement of the parallel movement piece. That is, the movable member moves in a fan shape while being separated from the fixed member.

For example, if this hinge is mounted on the gaming machine with the main frame of the gaming machine as the fixed side member and the front frame of the gaming machine as the movable side member, when the above-mentioned opening operation is performed, the front frame will be the main frame. The rocking is released while being separated from. On this occasion,
An air gap is generated between the front frame and the main frame according to the amount of parallel movement of the parallel movement piece.

Therefore, for example, it is possible to secure a distance allowance corresponding to the above-mentioned gap also between the adjacent game machine or the ball lending machine installed between the game machines and the opened front frame. Therefore, for example, the front frame can be opened at a larger angle than in the conventional case, and maintenance inside the gaming machine or the like becomes easier. In addition, for example, it is possible to project the upper and lower trays by the amount corresponding to the above-mentioned gap, and the volume of the upper and lower trays can be increased.

Further, since the front frame moves as described above, it is not necessary to install a part of the hinge so as to project from the main frame. Therefore, it is possible to prevent the appearance of the gaming machine from being impaired by the protrusion of the hinge. As described above, if the hinge of the first invention is attached to the gaming machine, it is possible to avoid the appearance of the gaming machine being damaged by the hinge.

Further, it is possible to increase the volume of the saucer by projecting the saucer forward (on the side of the player). on the other hand,
In the gaming machine of the second invention, since the main body frame and the front frame are connected via the hinge of the first invention described above, the effects as described above can be obtained by the operation as described above.

When the occurrence of the winning state in the second invention is illustrated, for example, in a pachinko machine, a game ball enters a winning opening (prize chucker), and in an arepachi, for example, to four or more adjacent chuckers. That is, a predetermined combination such as a game ball entering is realized.

[0014]

Next, a preferred embodiment of the present invention will be described.
FIG. 1 is a front view of a pachinko machine 10 as a game machine of the present invention, which includes a well-known game board 12. The front side of the game board 12 is a double glass 16a, 16b which is attached to a front frame 14 which is almost entirely made of plastic through a glass frame 13 which is almost entirely made of plastic and which includes a decorative portion 13a.
A game area 18 is formed between the game board 12 and the inner glass 16a and the decorative portion 13a. On the upper part of the front frame 14, a big hit lamp 20 which is turned on when a so-called big hit state occurs is assembled. Further, the front frame 14 is a lock 2 provided on the right side portion 22.
By operating 4, the opening / closing can be performed around the extension hinges 176a and 176b (details will be described later) mounted on the back surface side of the left side portion 26.

Below the front frame 14, there is disposed a dish member 32 made of plastic and integrally provided with an upper tray 28 and a lower tray 30. The upper tray 28 and the lower tray 30 are respectively provided with an upper tray outlet 34 and a lower tray outlet 36 for ejecting game balls from the inside of the pachinko machine 10. Further, the dish member 32 is provided with a speaker surface 38 formed of a plurality of small holes, and a speaker (not shown) that emits sound according to a game state is mounted on the back side of the speaker surface 38. Furthermore, in the dish member 32, the game balls supplied from the upper tray 28 are provided in the game area 18
A launch handle 40 for operating a motor (not shown) for launching and a stop switch 42 for temporarily stopping the launch of the game ball are installed. Further, a skirt plate 43 is installed below the dish member 32.

The dish member 32 can be opened and closed about the extension hinges 176c and 176d (details will be described later) mounted on the left back side, but is locked and kept closed in the right back side during normal use. ing. Further, during normal use, the dish member 32 is prevented from being opened by pressing the upper side portion by the front frame 14. Therefore, in order to open the dish member 32, it is necessary to open the front frame 14 and unlock the right rear side.

As shown in FIG. 2, the back side of the pachinko machine 10 is made of plastic, which is a member for supporting each member of the pachinko machine 10 and also for mounting the pachinko machine 10 on a game machine installation island (hereinafter simply referred to as an island). A body frame 44 is arranged, and the front frame 14 and the dish member 32 described above are connected to the body frame 44 via hinges. The main body frame 44 supports the game board 12, a control board 46 incorporating electrical components such as an LSI for controlling the operation of the accessory and changing the game conditions, a cover 46a for protecting the control board 46, and the like. Backplane 4
8 are assembled. Although not shown,
On the back side of the game board 12, well-known members such as a game ball detection sensor installed in a winning ball passage or a winning opening, a lead object connected to an accessory, a lamp or the like are arranged.

At the upper end of the back board 48, a plastic prize ball tank 50 for storing game balls supplied from a ball supply path (not shown) installed at the upper part of the island is installed. The prize ball tank 50 has a load sensor 5 for detecting the presence or absence of a game ball based on the presence or absence of the load of the game ball slightly to the left of the center.
2, a prize ball outlet 54 from which game balls can flow out is provided below the prize ball tank 50. The prize ball outlet 54 is connected to a prize ball discharge device 58 via a prize ball guide gutter 56 made of transparent plastic that allows the game balls to flow down while being aligned. A load sensor 60 is provided at an intermediate portion of the prize ball guiding gutter 56, and can detect a guiding state of the game ball.

The prize ball discharging device 58 is, for example, Japanese Patent Laid-Open No. 5-4.
As described in Japanese Patent No. 2248, a flight screw driven by a stepping motor 62 is provided, but it is possible to detect passage of a game ball by a photo sensor 66 installed in front of the discharge port 64.

As shown in FIG. 3, this photo sensor 66
Signal is input to the counter 68. The counter 68 is
The number of discharged game balls is counted based on the signal SP of the photo sensor 66, and the drive signal S is sent to the motor control circuit 70 until the set number (for example, 15) of game balls is counted.
When K is output and the set number of game balls is counted, the output of the drive signal SK is stopped and the count number is reset to 0. The motor control circuit 70 receives the winning signal SN from the winning signal generating circuit 72 which outputs the winning signal SN when the winning is detected. When the winning signal SN is input, the motor control circuit 70 causes the stepping motor 6 to eject the game ball during the time when the drive signal SK continues.
2 is rotated at a pitch corresponding to the discharge of one game ball.
Therefore, the stepping motor 62 accurately discharges the set number of game balls and stops.

However, for some reason, the prize ball discharging device 5
When the supply of game balls to 8 is insufficient, the stepping motor 62 will idle, so the motor control circuit 7
Even if the drive signal SK of the counter 68 is input, 0 rotates the stepping motor 62 by a predetermined number of pitches corresponding to the discharge of 30 game balls and stops it.
In such a case, for example, when the clerk repairs the problem and then turns on the reset switch 74, the winning signal S
The motor control circuit 70 rotates the stepping motor 62 in the same manner as when N is input. In this case, the discharge of the set number of game balls has not been completed, so the counter 68 continues to count to the count number at the time of the occurrence of the above problem. Therefore, for example, when the above-mentioned trouble occurs,
Assuming that the individual game balls have been discharged, the counter 68 counts 11 to 15. Therefore, the five game balls that have not been discharged due to the occurrence of the problem are discharged, and the stepping motor 62 is stopped. In this way, the prize ball discharging device 58 additionally discharges the uncompleted number after the problem is resolved, so that the game balls corresponding to the winning number are accurately discharged.

As shown in FIG. 2, below the discharge port 64 of the prize ball discharge device 58, a prize ball discharge gutter 76 for guiding the game balls discharged from the prize ball discharge device 58 is connected. The prize ball discharge gutter 76 includes a back plate 48 and a back plate 7 made of transparent plastic.
It is formed by 8, 80, and is provided with a bent portion 82 for restricting the falling speed of the game ball and an oblique portion 84 continuous with the bent portion 82. The skew portion 84 is connected to a game ball sorting mechanism 88 for sorting and discharging game balls to the upper tray 28 and the lower tray 30. Therefore, the game balls discharged from the prize ball discharge device 58 are guided to the game ball distribution mechanism 88 via the prize ball discharge gutter 76.

Further, a ball pulling trough 92 is connected to the prize ball discharging trough 76 through a damper 90 driven by a solenoid (not shown) in the oblique portion 84. This ball drain gutter 92
For example, when removing the pachinko machine 10 from the island, this is a path for discharging the game balls stored in the prize ball tank 50, the prize ball guide gutter 56, etc. to the outside of the machine. Is turned on, the damper 90 is driven in the direction of arrow A to shut off the skewed portion 84 and connect the prize ball discharge gutter 76 to the ball drain gutter 92. At the same time, the prize ball discharging device 58 operates to discharge the game balls from the prize ball tank 50. The discharged game ball is discharged to the outside of the machine through the prize ball discharge gutter 76 and the ball removal gutter 92.

In the conventional game machine, since the damper installed on the upstream side of the prize ball discharging device is mechanically operated by the operation pin to perform the punching work, the operation pin is used for the damper operation. It was necessary to provide an operation hole near the damper for inserting the. For this reason, the degree of freedom of the installation position of the damper and the installation position of the operation hole is low, which sometimes limits the configuration of the entire gaming machine.

However, in the pachinko machine 10 of this embodiment,
Since the damper 90 and the prize ball discharging device 58 are electrically operated as described above, the installation positions of the damper 90 and the ball drop switch are not practically limited, and the degree of freedom in mechanism arrangement is increased. In the game ball distribution mechanism 88, an upper plate introducing port 96 communicating with the upper receiving plate 28 and a lower plate introducing port 98 communicating with the lower receiving plate 30 are opened adjacent to each other. Upper plate inlet 9
A barrier 100 having a height about the radius of the game ball is installed between 6 and the lower plate introduction port 98, and a communication port 102 through which the game ball can pass is provided above the barrier 100. Therefore, the game ball dropped from the prize ball discharge gutter 76 is normally the barrier 100 from the upper plate introduction port 96 side to the lower plate introduction port 9
It is guided to the upper tray 28 while being prevented from moving in the horizontal direction to the 8 side. However, when a large number of game balls are accumulated in the upper tray 28 due to continuous winning, etc., the upper tray inlet 96
There is a case where the vicinity is filled with game balls and the game balls cannot enter the upper plate inlet 96. In such a state, the game balls discharged from the prize ball discharge gutter 76 are interrupted in the passage by the game balls staying near the upper plate introduction port 96, so that they pass through the communication port 102 above the barrier 100 and the lower plate. The water overflows to the inlet 98 and is guided to the lower tray 30.

Adjacent to the game ball distribution mechanism 88, there is provided a prize ball collecting gutter 104 which concentrates and guides the prize balls from the game board 12. A winning ball discharging device 106 is installed on the exit side of the winning ball collecting gutter 104. As shown in FIG. 4, the ball passage 108 of the winning ball discharging device 106 has an upper end portion 108a and a lower end portion 108b on the winning ball collecting gutter 104 side.
It is a shape in which the cylindrical portions of are connected by the side wall portion 108c. In addition, a pair of openings 1 facing each other is provided at the center of the side wall 108c.
10, 112 are provided and these openings 110, 112 are provided.
Proximity switch 114 is installed throughout. In addition, in the ball passage 108, a pair of plate portions 116a and 116b pivotally supported by the upper end portion 108a and plate portions 116a and 116b.
Swing member 1 including a ball receiving portion 118 provided at the tip of
20 are installed. The swing member 120 is driven by a solenoid 124 connected via a wedge member 122 and is swingable in the ball passage 108. A spring 126 for returning the solenoid 124 is attached to the wedge member 122.

With such a configuration, the winning ball gathering gutter 104
The game ball guided from the winning ball discharging device 106 to the ball receiving portion 118 is dropped in the ball passage 108 and temporarily stopped at the ball receiving portion 118.
Here, the proximity switch 114 is turned on. The signal from the proximity switch 114 is input to, for example, the winning signal generation circuit 72 to operate the stepping motor 62 of the prize ball discharging device 58 by the winning signal SN, and is also input to the control board 46 to be used for a predetermined control operation. It Next, when the swing member 120 is swung in the direction of the arrow B by the operation of the solenoid 124, the game ball has a ball receiving portion 118 and a ball passage 108.
It falls through the gap formed between the and. On this occasion,
If there is a next game ball, the wedge member 122 prevents the game ball from falling. When the wedge member 122 is further retracted due to the return of the solenoid 124, the game ball drops and stops on the ball receiving portion 118, and the proximity switch 114 operates as described above. In this way, the winning game balls are discharged exactly one by one.

As shown in FIG. 2, the winning ball discharging device 106.
A prize winning ball discharge gutter 128 as a passage for the game balls discharged from the prize winning ball discharging device 106 is provided below.
Further, on the left side of the winning ball discharging device 106, an out ball discharging gutter 129 connected to an out hole (not shown) opened at the bottom of the game board 12 is installed. As shown in the figure, the winning ball discharge gutter 128 and the out ball discharge gutter 129 join together and are connected to a merge gutter 131, and the ball gutter 92 also joins the merge gutter 131. Further, a recovery path (not shown) installed on the island is connected to the outlet 131a of the confluent trough 131.

With such a configuration, when the pachinko machine 10 is in operation (during a game), the winning ball passes through the winning ball discharging device 106 and the winning ball discharging trough 128 and joins the trough 131.
The out-ball is guided to the confluent gutter 131 through the out-ball discharge gutter 129, and both are discharged to the recovery path. In addition, the game ball guided to the ball drop trough 92 in performing the above-described ball drop work is discharged to the recovery path via the confluence trough 131.

As described above, all of the winning balls, the out balls, and the game balls discharged by the ball removing work are discharged from the junction trough 131. Therefore, the recovery channel is a confluent gutter 1.
Since it is only necessary to connect to the outlet 131a of 31 and it is not necessary to provide the pachinko machine 10 and the recovery path at a plurality of locations, the connection between the pachinko machine 10 and the island can be simplified.

As shown in FIGS. 2 and 5, the main body frame 44

The purpose of this is to prevent damage to the main body frame 44 due to nailing when installing on the island. By adjusting the plate thickness t of the spacer 132, the installation height of the main body frame 44 can be adjusted. Therefore, if the spacer 132 having the increased plate thickness t is incorporated into the pachinko machine 10 using the Kanto frame size main body frame 44, the Kanto frame size pachinko machine 10 can be installed on the Kansai frame size island. . Therefore, it is not necessary to manufacture two types of main frame 44, the Kanto frame and the Kansai frame. Since the Kansai frame is larger in width than the Kanto frame, the width can be adjusted by using a vertical spacer that can be installed along the side surface of the body frame 44.

Needless to say, the size of the frame of a gaming machine such as a pachinko machine is 809 mm long and 521 mm long in the Kanto frame, and 818 mm long and 530 mm wide in the Kansai frame. As shown in FIG. 5, a steel reinforcing rail 134 is bolted to the first side wall 44b of the main body frame 44 that supports the load of the front frame 14, the dish member 32, and the like. The second side wall 44c facing the first side wall 44b has L members 136 and 136 for locking the front frame 14, and a dish member 32.
A lower locking member 138 for locking is attached. The lower locking member 138 is capable of reciprocating along the arrow Z direction within a predetermined range and is urged upward in the drawing by a spring, but the pressing portion 138a provided in the upper portion is pressed downward in the drawing. Thus, the lower locking member 138 can be lowered against the biasing force of the spring.

As shown in FIG. 6, the back board 48 has the first side wall 44 of the body frame 44 via the two hinges 139 and 139.
