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 1 that is almost entirely equipped with a plastic frame 13 including a decorative portion 13a and is attached to a front frame 14 made of plastic.
It is covered with 6a, 16b, and 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 can be opened and closed by operating the lock 24 provided on the right side portion 22 around the extension hinges 176a and 176b (details will be described later) mounted on the back side of the left side portion 26. is there. Below the front frame 14, a dish member 32 made of plastic and integrally provided with an upper tray 28 and a lower tray 30 is arranged. 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. The dish member 32 has a speaker surface 38 including a plurality of small holes.
Is provided, and a speaker (not shown) that emits sound according to the game state is mounted on the back side of the speaker surface 38. Below the speaker surface 38, a pin hole 39 for inserting a wire-shaped pin is formed through the front frame 14. When a pin is inserted into the pin hole 39, the built-in pin insertion detection switch 39a closes the contact. 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. This dish member 32 is an extension hinge 176c attached to the back left side,
Although it can be opened and closed around 76d (details will be described later), it is locked on the right rear side and kept closed during normal use. 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 it on a game machine installation island (hereinafter, simply called 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 frame 44 is provided with a game board 12, a control board 46 in which electric parts such as an LSI for performing operation control and modification of game conditions are incorporated, and a cover 46a for protecting the control board 46. Back board 4
8 is assembled. Although not shown,
On the back surface 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 accessory, a lead wire connected to a lamp and 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. In the prize ball tank 50, a load sensor 52 for detecting the presence or absence of the game ball depending on the presence or absence of the load of the game ball is installed on the slightly left side of the center, and at the bottom of the prize ball tank 50, the prize ball from which the game ball can flow out. An outlet 54 is provided. The prize ball outlet 54 is a transparent plastic prize ball guide gutter 56 that allows game balls to flow while being aligned.
It is connected to the prize ball discharging device 58 via. Further, a load sensor 60 is installed in the middle portion of the prize ball guide gutter 56, and the guide situation of the game ball can be detected. The prize ball ejecting device 58 includes a flight screw driven by a stepping motor 62 as described in, for example, Japanese Patent Laid-Open No. 5-42248, but a photo sensor installed in front of the ejection port 64. The passage of the game ball can be detected by 66.

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, if the supply of game balls to the prize ball discharging device 58 is insufficient for some reason, the stepping motor 62 will idle, so the motor control circuit 70 receives the drive signal SK of the counter 68. However, for example, the stepping motor 62 by a predetermined pitch number corresponding to the discharge of 30 game balls.
Turn to stop. In such a case, for example, when the clerk repairs the defect and then turns on the reset switch 74, the same as when the winning signal SN is input,
The motor control circuit 70 rotates the stepping motor 62. 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, if 10 game balls have already been discharged at the time of occurrence of the above-mentioned trouble, the counter 68 will count 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.

The ball removal signal SI from the pin insertion detection switch 39a is input to the motor control circuit 70. The ball removal signal SI is also input to the solenoid drive circuit 71, and the solenoid drive circuit 71 drives the ball removal gutter opening solenoid 73. The motor control circuit 70 and the solenoid drive circuit 71 detect the pin insertion detection switch 39 when a pin is inserted into the pin hole 39 penetrating the front frame 14 described above.
The ball removal signal SI from a is input to drive the stepping motor 62 and the ball removal gutter opening solenoid 73 for a predetermined time (about 2 minutes in this embodiment). 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.
Are connected. The prize ball discharge trough 76 is formed by the back plate 48 and the back plates 78 and 80 made of transparent plastic, and has a bent portion 82 for restricting the falling speed of the game ball and an oblique portion 84 continuous to the bent portion 82. I have it. The oblique portion 84 is connected to a game ball distribution mechanism 88 for distributing and discharging the 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 removal gutter 92 is connected to the prize ball discharge gutter 76 at a slanting portion 84 via a damper 90 driven by the ball removal gutter opening solenoid 73. The ball pullout gutter 92 is a route for discharging the game balls stored in the prize ball tank 50, the prize ball guide gutter 56, and the like to the outside of the machine when the pachinko machine 10 is removed from the island, for example. When a pin is inserted into the pin hole 39 and the pin insertion detection switch 39a is turned on, the ball gutter opening solenoid 73 is driven for a predetermined time to drive the damper 90 in the direction of arrow A to block the oblique portion 84 and discharge the prize ball. The gutter 76 and the ball gutter 92 are connected. In addition, by driving the stepping motor 62 for a predetermined time, the prize ball discharging device 58 operates to discharge the game balls from the prize ball tank 50. The discharged game balls are discharged to the outside of the machine through the prize ball discharge gutter 76, the ball removal gutter 92 and the confluence gutter 131. In the conventional gaming machine, the damper installed upstream of the prize ball discharging device is mechanically operated by the operation pin to perform the ball-punching work, so the operation pin is inserted for the damper operation. It was necessary to provide an operation hole near the damper. 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. Further, there is a problem that a ball draining gutter needs to be provided from a damper installed on the upstream side of the prize ball discharging device to a lower part of the game machine body, resulting in a complicated and large structure. However, the pachinko machine 10 of the present embodiment
Then, as described above, the damper 90 and the prize ball discharging device 58
Is electrically operated, the installation positions of the damper 90 and the ball drop switch are practically not limited, and the degree of freedom in arranging the mechanism is increased. That is, in the present embodiment, the damper 90 is provided in the oblique portion 84 of the prize ball discharge gutter 76, and the game ball passage to the oblique portion 84 is shared regardless of the prize ball discharge operation or the ball removal operation. It's simplified.

The game ball distribution mechanism 88 is an upper tray 28.
An upper plate introducing port 96 communicating with the lower plate and a lower plate introducing port 98 communicating with the lower receiving plate 30 are opened adjacent to each other. A barrier 100 having a height about the radius of the game ball is installed between the upper plate introduction port 96 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. ing. Therefore, the game ball dropped from the prize ball discharge gutter 76,
Normally, the barrier 100 prevents horizontal movement from the side of the upper plate introducing port 96 to the side of the lower plate introducing port 98, and the upper tray 28
Will be led to. However, if a large number of game balls are accumulated in the upper tray 28 due to continuous winning, etc., the game balls may fill up to the upper plate introduction port 96, and the game balls may not be able to enter the upper plate introduction port 96. . The game ball discharged from the prize ball discharge gutter 76 in such a state is blocked by the game ball staying in the vicinity of the upper plate introduction port 96, and therefore passes through the communication port 102 above the barrier 100 and the lower plate. It overflows to the inlet 98 side and is guided to the lower tray 30. Adjacent to the game ball distribution mechanism 88, a prize ball collecting gutter 104 that concentrates and guides the prize balls from the game board 12 is installed. 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 winning ball discharging device 106.
The ball passage 108 of the winning ball collecting gutter 104 side of the upper end 10
8a and the lower end portion 108b are connected to the side wall portion 108c.
The shape is connected with. Further, a pair of openings 110 and 112 facing each other are provided in the central portion of the side wall portion 108c, and the proximity switch 11 extends over these openings 110 and 112.
4 are installed. Further, in the ball passage 108, a pair of plate portions 116a, 116 pivotally supported by the upper end portion 108a are provided.
b, a swing member 120 including a ball receiving portion 118 provided at the tips of the plate portions 116a and 116b is installed. The swing member 120 is driven by a solenoid 124 connected via a wedge member 122, and the ball passage 10
It is possible to swing within 8. A spring 126 for returning the solenoid 124 is attached to the wedge member 122. With such a configuration, the game ball guided from the winning ball collecting trough 104 to the winning ball discharging device 106 falls in the ball passage 108 and is 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 swinging member 120 is swung in the direction of the arrow B by the operation of the solenoid 124, the game ball falls through the gap formed between the ball receiving portion 118 and the ball passage 108. At this time, if there is a next game ball, this game ball is prevented from falling by the wedge member 122. When the wedge member 122 is further retracted due to the return of the solenoid 124, this game ball drops and stops on the ball receiving portion 118, and as described above, the proximity switch 11
4 works. 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 balls pass through the winning ball discharging device 106 and the winning ball discharging trough 128, and the confluent trough 13
1, 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. In this way, all of the winning balls, the out balls, and the game balls discharged by the coin removing work are merged gutter 1
It is discharged from 31. Therefore, the recovery path is
Since it is only necessary to connect to one outlet 131a 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 FIG. 2 and FIG. 5, eight engaging pieces 43a provided on the back surface of the hem plate 43 are engaged with the eight engaging openings 130 provided on the lower portion of the main body frame 44, respectively. Thus, the body frame 44 and the hem plate 43 are connected. In addition, body frame 4
A pair of spacers 132, 132 is housed in the recess 44 a formed at the bottom of the No. 4. These spacers 132 prevent the body frame 44 from being damaged by nailing when the pachinko machine 10 is installed on the island. However, by adjusting the plate thickness t of the spacer 132, the body frame 44 is adjusted. The installation height of 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 for gaming machines such as pachinko machines is 809 mm long and 52 mm wide for the Kanto frame.
1 mm, the Kansai frame is 818 mm long and 530 mm wide.
