[0005]

Embodiments of the present invention will be described below in detail with reference to the drawings. In a pachinko game shop, control and circulation of balls are performed by using a group called an island constituted by arranging a plurality of pachinko machines (pachinko machines) 1 as one constituent unit. In general, the island includes a pachinko machine 1 arranged in a back-to-back manner, a ball supply gutter 2 provided above the pachinko machine 1, a ball collection gutter 3 provided below the pachinko machine 1, and a ball collection gutter 3. A lifting device (not shown) for transporting the collected balls to the ball supply gutter 2 and a cleaning device (not shown) for cleaning the collected balls are appropriately disposed.

The ball supply gutter 2 is formed with a downward slope so that the balls can flow down from the lifting device to the pachinko machine 1 located at the end of the island, and the ball supply pipe 4 branches to each pachinko machine 1. Let it. Then, the ball flowing down from the ball supply gutter 2 is supplied to the prize ball tank 5 by causing the tip of the ball supply pipe 4 to face the prize ball tank 5 provided in the pachinko machine 1. Between the tip of the ball supply pipe 4 and the prize ball tank 5, a prize ball replenishing device (ball replenishing means) 6 is disposed on a frame 7 constituting an island.

The pachinko machine 1 is arranged corresponding to the prize ball replenishing device 6. The pachinko machine 1 has a wooden frame 1a supported and fixed to a frame 7 constituting an island. A front frame 1b is provided on one side in front of the front side so as to be freely opened and closed. Most of the main components constituting the pachinko machine 1 are mounted on the front frame 1b, and the above-mentioned prize ball tank 5 is also provided on the upper rear surface thereof. The opening / closing operation is performed on the frame 1a.

When the front frame 1b of the pachinko machine 1 is closed, the prize ball supply device 6 replenishes the balls flowing from the ball supply gutter 2 to the prize ball tank 5, and when the front frame 1b is open. And a function of sealing the ball outlet of the ball supply pipe 4 so that the ball flowing from the ball supply gutter 2 does not flow out of the ball supply pipe 4.

The winning ball replenishing device 6 is provided with a detection lever (position movable member) 60 protruding downward as shown in FIG. As shown in FIGS. 2 and 3, the detection lever 60 does not receive a load when the front frame 1b is open, and thus moves to the first position by the urging force. When the front frame 1b is closed, the award is detected. The prize ball supply device 6 receives the pressing force by the back wall 5a of the ball tank 5 and moves to the second position against the urging force. When 60 moves to the first position, the front frame 1b is opened and the above sealing function is exerted to stop supplying balls to the prize ball tank 5, and when the detection lever 60 moves to the second position. Then, the supply of the ball to the winning ball tank 5 is started assuming that the front frame 1b is closed.

The prize ball supply device 6 has a hitting function of stopping the supply of balls in order to stop the game when the payout of the predetermined number of prize balls is completed.

Further, as shown in FIGS. 2 and 3, the prize ball replenishing device 6 is provided with a microswitch (open / close detecting means) 100 which operates according to the detection lever 60. When the detection lever 60 is at the first position, the front frame opening signal is output, and when the detection lever 60 is at the second position, the front frame closing signal is output.
That is, in this embodiment, the micro switch 100 is turned on / off in accordance with the operation of the detection lever 60 of the prize ball supply device 6, and the opening and closing of the front frame 1b is detected. The configuration for realizing each of the sealing function, the striking function, and the opening / closing detection function of the front frame 1b, and the operation thereof will be described later.

The above prize ball replenishing device 6 is constructed by assembling a metal plate to a base substrate 30 having a substantially U-shaped cross section. 7.

As shown in FIG. 4, the base substrate 30 has elongated slide surfaces 31a and 31b formed by bending both side edges of a front substrate 30a backward and further bending both ends outward. This slide surface 31a, 3
1b is slidably attached to the fixing plate 8 as described later. Further, a plurality of locking through holes 31 are provided in the lower half of the side surface 31c rising from one of the slide surfaces 31a.
d ... is open.

The fixing plate 8 is formed of a substantially rectangular metal plate, and is formed by bending an upper half portion from the upper end to a height of about 1/3 of the width of the plate at the center in the longitudinal direction and horizontally bending it backward.
a, and a cutout portion 8b formed by cutting out the center at the lower end side
A guide portion 8c elongated in the plate width direction formed on both side edges;
8d. The notch 8b is for avoiding interference with the fixing plate 8 when a later-described ball introduction gutter 50 rotates upward and is in a substantially horizontal state. Guide paths having a U-shaped cross section are formed in the guide portions 8c and 8d. Further, the lower end of the guide portion 8c and the notch 8b
4, an engaging piece 89 is provided so as to be movable in the left-right direction in FIG. 4 and urged leftward by a spring 89b. The engaging claw 89a formed to protrude at one end is also constantly urged toward the guide portion 8c. Then, in order to move the engaging claw 89a rightward against the urging force, the operation portion 89e formed by bending the lower end of the engaging piece 89 backward is pushed rightward with a finger.

In order to mount the prize ball supply device 6 to the island frame 7 as shown in FIGS. 1 to 3, first, the mounting surface 8a of the fixing plate 8 is mounted on the frame 7, and the front side edges of the fixing plate 8 are provided. Of the base substrate 30 from below into the guide portions 8c and 8d
The slide surfaces 31a, 31b are applied to the guide portions 8 thereof.
c and 8d are fitted into the U-shaped guide paths. At this time, the upper end of the side surface 31c of the base substrate 30 is
c, the operating portion 89e is pushed rightward to move the engaging claw 89a,
In this state, the base substrate 30 is further raised to pass through the engaging claws 89a, and height adjustment is performed to optimize the positional relationship with the winning ball tank 5. When the finger is released from the operation portion 89e at the adjustment position, the engaging claw 89a is urged toward the side surface 31c and moves, and enters one of the locking through holes 31d provided in the side surface 31c. Locked. In this manner, the base substrate 30, that is, the prize ball supply device 6
And the height adjustment with respect to the prize ball tank 5 is completed.

Next, the configuration of the supply counter 10 built in the prize ball supply device 6 will be described.

The prize ball replenishing device 6 has a replenishment counter 10 built in, and the replenishment counter 10 is formed as a single unitized member as shown in FIGS. 5 to 7, for example. That is, the supply counter 10
Is formed by forming a vertical ball passage 12 in a storage box 11 formed in a substantially rectangular parallelepiped shape, and making a tip end portion of a sprocket 13 rotatably shafted face the ball passage 12. That is, from the side surface of the ball passage 12 through which one ball can pass, the tip portion of the sprocket 13 in which ten ball engaging portions 14 in which one ball can be recessed are arranged on the circumference is recessed. . Thereby, when the ball passes through the ball passage 12,
The ball is fitted into the ball engaging portion 14 and rotates the sprocket 13 1/10.

A locking claw 15 is projected from the side surface of the sprocket 13, and a turning piece 16 lockable to the locking claw 15 is rotatably mounted coaxially with the sprocket 13. A magnet 17 is embedded in the rotating piece 16 to act on a reed switch 18 to be described later and to function as a weight.

On the other hand, a circuit board 19 in which a reed switch 18 and the like are disposed in the storage box 11 so as to emit one pulse when the magnet 17 of the rotating piece 16 is actuated is mounted on the sprocket 13. And placed in a superposed state.

A stopper lever 20 faces the outer peripheral surface of the sprocket 13. The stopper lever 20 has a bent portion 21 extending downward at one end and a weight portion 22 formed at the other end. The weight portion 22 can be fitted into the ball engaging portion 14 of the sprocket 13. The stopper lever 20 functions as a part of a sealing unit described later.

Further, a suction magnet 23 for attracting the magnet 17 of the rotating piece 16 to make the rotating piece 16 stand by at a standby position is provided inside the storage box 11. Therefore, the rotating piece 16 is at the standby position where it is attracted by the attraction magnet 23 most of the time even when the sprocket 13 rotates (the position shown in FIG. 6). On the other hand, when the sprocket 13 rotates by a predetermined angle due to the passage of the ball, and the locking claw 15 of the sprocket 13 abuts against the rotating piece 16 from below, the suction of the attraction magnet 23 is shaken off and the rotating piece 16 is moved upward. Rotate. Then, when the rotating piece 16 exceeds the vertex, the rotating piece 16 falls rapidly and is attracted by the attraction magnet 23, so that the rotating piece 16 returns to the standby position. At this time, the magnet 17 provided on the rotating piece 16 acts on the reed switch 18 to generate one pulse. That is, the rotating piece 1 provided with the magnet 17
6 and the reed switch 18 and the like exhibit a function of transmitting a predetermined count signal in accordance with the rotation of the sprocket 13.

The replenishment counter 10 constructed as described above.
Is a mounting surface 2 attached to the rear side of the storage box 11.
5, it is detachably attached to the base substrate 30.

Next, of the configuration of the prize ball replenishing device 6, a configuration for realizing the above-described sealing function will be described. This configuration includes first sealing means for sealing using the stopper lever 20 of the replenishment counter 10 and a ball introduction gutter 50 described later.
Sealing means for sealing the ball inlet portion of the
And third sealing means for sealing the sphere outlet portion of the sphere.

The first sealing means is constituted by locking the stopper lever 20 of the replenishment counter 10 described above. For this reason, the storage box 11
An opening 24 (FIG. 5) is opened on the upper surface of the. As shown in FIG. 6, the rotation of the sprocket 13 is prevented by inserting the pressing claw 40 and pressing the stopper lever 20 from the opening 24. That is, when the stopper lever 20 is pressed, the weight portion 22 provided at one end of the stopper lever 20 fits into the ball engaging portion 14 of the sprocket 13 to prevent the sprocket 13 from rotating.

If the sprocket 13 does not rotate, the ball stays in the ball engaging portion 14 in the ball passage 12, and the ball cannot pass.

When the supply of the sphere is stopped by preventing the rotation of the sprocket 13 as described above, the sphere is stopped in the ball passage 12 in which the sphere is aligned. Therefore, the operation does not become unstable. That is, the supply of the sphere can be reliably stopped.

On the other hand, the second sealing means is located downstream of the storage box 11 and prevents the ball from flowing out on the outlet side of the ball passage 12. For this reason, in the illustrated example, the plate portion 44 having the ball passage opening 41 is configured to face the lower side of the ball passage 12.

That is, a turning lever 42 that can turn in the horizontal direction about a vertical axis 43 provided on the base substrate 30 as a fulcrum.
And a plate portion 44 interlocking with the rotation lever 42 is rotatably provided on the vertical shaft 43, and a ball passage 41 is opened in the plate portion 44. The ball passage opening 41 has a shape of a long hole formed to be slightly horizontal, and in a state where the center of the ball passage opening 41 and the center of the ball passage 12 provided in the storage box 11 are deviated (FIG. 16), Although the sphere cannot pass through the sphere passage opening 41, the sphere can pass when the centers match (FIG. 17). That is, as described later, in a state where the front frame 1b is opened and the prize ball tank 5 is not located below the prize ball supply device 6, the center is displaced.
Since the plate 44 around the ball 1 extends below the ball passage 12 and narrows the outlet of the ball passage 12 to a diameter equal to or less than the diameter of the ball, the ball is stopped by the plate 44.

On the other hand, when the front frame 1b is closed and the winning ball tank 5 faces below the winning ball replenishing device 6, the rotating lever 42
Is rotated horizontally, and the center of the ball passage 12 and the ball passage port 4
1 coincides with the center. Therefore, the ball flowing down the ball passage 12 flows into the ball passage 41.

When the rotating lever 42 is rotated, the supply of balls is stopped by the sprocket 13 of the replenishment counter 10, so that a small number of balls are present downstream of the ball passage 12. Only the ball pressure from the ball supply pipe 4 does not act, so that it can rotate without any trouble.

Below the ball passage opening 41 of the plate portion 44,
A ball introduction gutter 50 that introduces a ball into the prize ball tank 5 faces. This ball introduction gutter 50 has a horizontal shaft 51 provided in a horizontal direction.
Is configured to be rotatable about 90 degrees in the vertical direction with the fulcrum as a fulcrum (FIGS. 11 and 13).

The ball introduction gutter 50 has a ball passage tube portion 52 through which one ball can pass, and in the illustrated example, is formed in a substantially rectangular tube shape. In addition, the ball inlet 53 of the ball passage tube portion 52
Opens at the upper end surface in the longitudinal direction of the ball introduction gutter 50, and the ball outlet 54 opens at the downstream side end surface. Therefore,
When the ball introduction gutter 50 rotates downward and the ball introduction port 53 communicates with the ball passage port 41, the ball flowing into the ball passage pipe 52 from the ball introduction port 53 turns around the lower end. About 9
The angle is converted to 0 degrees, and flows sideways from the ball outlet 54 into the prize ball tank 5 (FIG. 11).

On the other hand, when the ball introduction gutter 50 is turned upward and is in a substantially horizontal state, the ball introduction port 53 does not communicate with the ball passage port 41, so that the ball cannot flow into the ball passage tube portion 52. . In this case as well, since the supply of the ball is already stopped by the sprocket 13 of the replenishment counter 10, the ball introduction gutter 50 is not affected without any direct ball pressure from the ball supply pipe 4. Rotate. Moreover,
When the sprocket 13 of the replenishment counter 10 is stopped, the ball passing through the ball introduction gutter 50 is sealed by third sealing means described later.

The third sealing means is arranged side by side with the ball introduction gutter 50. That is, on the side of the ball introduction gutter 50,
The closing shaft 55 is rotatably pivoted by its own weight coaxially with the ball introduction gutter 50 by the horizontal shaft 51.
Is made to face the ball outlet 54. In addition, a long hole 56 is opened in the closing plate 55, and the long hole 5 is formed.
6, a guide pin 57 formed by screwing a screw on the side surface of the ball introduction gutter 50 is loosely fitted.

Therefore, when the ball introduction gutter 50 is turned upward (the state shown in FIG. 13), the closing plate 55 is
The guide pin 57 locks on the upper end of the elongated hole 56, but the distal end closing portion 55 a of the closing plate 55 closes a part of the ball outlet 54 because the guide pin 57 locks on the upper end of the long hole 56. For this reason, the ball P in the ball introduction gutter 50 is locked to the distal end blocking portion 55 a of the blocking plate 55 and cannot flow out from the ball outlet 54.

On the other hand, when the ball introduction gutter 50 rotates downward, the closing plate 55 also rotates downward together with the ball introduction gutter 50. When the side edge of the closing plate 55 comes into contact with the locking plate 58 attached to the lower surface portion of the base substrate 30, the closing plate 55
Remains at that place, but the ball introduction gutter 50 further rotates and moves to a position where the guide pin 57 is located at the other end of the elongated hole 56 (the state of FIG. 11). For this reason, since the distal end closing portion 55a of the closing plate 55 comes off the ball outlet 54, the ball P can be led out.

Each of the above sealing means operates in conjunction with opening and closing of the front frame 1b of the pachinko machine 1. Therefore, the winning ball replenishing device 6 is provided with a detection lever 60 that operates according to the open / closed state of the front frame 1b and an interlocking unit that operates the sealing unit based on the operation of the detection lever 60.

The detection lever 60 is urged by a coil spring 62, which will be described later. When the front frame 1b is closed, the detection lever 60 comes into contact with the back wall 5a of the winning ball tank 5 provided on the front frame 1b. It is forcibly rotated to the second position and stopped. On the other hand, in a state where the front frame 1b is opened, the front frame 1b is separated from the back wall 5a of the prize ball tank 5 and becomes free, so that it rotates by the urging force of the coil spring 62 and stops at the first position.

The interlocking means provided between the detection lever 60 and the sealing means is, for example, according to the illustrated example, the detection lever 6.
A cam portion 61 is provided at one end of a rotating lever 42 that is continuous with zero, and a cam receiving portion 71 of a pressing lever 70 is slid on the cam portion 61 (FIGS. 8 and 9). That is, a substantially horizontal L-shaped rotating lever 42 having a long arm and a short arm is pivotally mounted on the vertical shaft 43 so as to be able to rotate horizontally in the middle of the long arm. A detection lever 60 is provided to extend downward, and the above-described cam portion 61 is formed at one end of a long arm of the rotating lever 42 in a slope shape.

A pressing lever 70 is brought into contact with the cam portion 61. As shown in FIG. 18, the upper arm and the lower arm of this pressing lever 70 are formed in an L-shape, and the upper arm extends with its tip bent rearward (toward the supply counter 10). A portion 75 is formed, and in the middle of the extending portion 75, a movable contact piece 101 of a microswitch 100 described later is formed.
A pressing claw 40 for pressing the stopper lever 20 of the replenishment counter 10 projects downward from the distal end of the extending portion 75.
The pressing lever 70 has a base end portion of the upper arm pivotally mounted on a support shaft 72 provided in the front-rear direction. A cam receiving portion 71 corresponding to the cam portion 61 is formed on the lower arm extending downward from the base end of the upper arm.

Therefore, when the detection lever 60 rotates with the opening and closing of the front frame, the rotation lever 42 rotates forward and backward, and the pressing lever 70 rotates left and right via the cam portion 61 and the cam receiving portion 71. Will move.

A helical spring 73 is wound around the support shaft 72 of the pressing lever 70, and the pressing lever 70 is urged counterclockwise (in FIG. 8). For this reason, usually, the pressing claw 40 is at a position where the stopper lever 20 of the replenishment counter 10 is pressed, and the pressing portion 49 is at a position where the movable contact piece 101 of the microswitch 100 is pressed.

The above-described coil spring 62 is stretched between the rotation lever 42 and the plate portion 44, and the rotation lever 42 and the plate portion 44 are linked via the coil spring 62.
An interlocking piece 45 is suspended from the plate portion 44, and a driving piece 81 of a driving lever 80 for rotating the ball introduction gutter 50 abuts on the interlocking piece 45. This drive lever 8
Reference numeral 0 denotes a vertically swingable pivot shaft 82, and a drive pin 83 provided at the tip is loosely fitted in a drive long hole 84 provided on the side of the ball introduction gutter 50. The driving piece 81 is erected on the base end side, and the driving piece 81 is in contact with the interlocking piece 45 described above. Further, the horizontal axis 8
2, a winding spring 85 is wound around the driving lever 80.
Is urged upward.

Therefore, in the normal state, the driving lever 80 is urged upward, so that the locking end of the tip locks on the lower edge portion of the base substrate 30, and the ball introduction gutter 50 is accordingly moved.ゞ In a state of being raised horizontally (FIG. 8, FIG. 1)
3). At this time, since the closing plate 55 descends by its own weight, the distal end closing portion 55a blocks a part of the ball outlet 54 (FIG. 1).
3).

On the other hand, when the front frame 1b is closed, the detection lever 60 rotates, and when the plate portion 44 pulled by the coil spring 62 rotates, the interlocking piece 45 pushes the driving piece 81 forward. , And the drive lever 80 rotates downward against the bias. Therefore, the ball introduction gutter 50 in which the drive pin 83 of the drive lever 80 is loosely fitted into the drive long hole 84.
Is guided downwardly by the driving long hole 84, so that the ball outlet 54 of the ball introduction gutter 50 is lowered, and the closing plate 5 is closed.
As described above, the distal end closing portion 55a of the fifth ball 5 is disengaged from the ball outlet 54 to allow the ball to pass therethrough, so that the ball can be supplied to the prize ball tank 5 (FIG. 11).

Next, a configuration for realizing the above-described hitting function will be described. In this configuration, according to the illustrated example, a so-called latching solenoid 90 capable of holding the position of the plunger by itself is used as a drive source.

That is, a substantially L-shaped striking lever 92 having at one end a striking claw 91 which substantially overlaps with the pushing claw 40 of the pushing lever 70 is connected to the support shaft 72 of the pushing lever 70.
The latching solenoid 90 is connected to the tip of a plunger 90a and the other end of the striking lever 92 by a rod-shaped spring 93.

Plunger 9 of latching solenoid 90
A return spring 90b is wound around 0a. Therefore, in a state where the plunger 90a is projected by the urging of the return spring 90b, the rod-shaped spring 93 presses the other end of the striking lever 92, so that the striking lever 92 rotates upward and the striking pawl 91 Is at a position off the stopper lever 20. Therefore, the sprocket 13 is rotatable, and the ball can pass through the ball passage 12.

On the other hand, when the plunger 90a is sucked, the striking lever 92 is pulled and pivots downward, and
1 presses the stopper lever 20. Therefore, the rotation of the sprocket 13 is stopped, and the supply of the ball is prevented. At this time, since the plunger 90a and the striking lever 92 are connected by the bar spring 93, even if the amount of rotation of the striking lever 92 is smaller than the sliding amount of the plunger 90a, an excessive force is applied to the plunger 90a. Does not work. In addition, since the latching solenoid 90 is used, once excited, the state is maintained until the next excitation, so that power is saved and there is no fear of heat generation.

Next, a configuration for realizing the function of detecting the opening and closing of the front frame 1b will be described. According to the illustrated example, this configuration uses a series of configurations interlocked with the detection lever 60, that is, uses the rotating lever 42, the cam portion 61, and the pressing lever 70. According to the operation of the detection lever 60, The pressing portion 49 of the pressing lever 70 presses the movable contact piece 101 of the micro switch 100.

The micro switch 100 has a base substrate 30
At one end of the upper surface of the micro switch 100, it is mounted laterally on a mounting surface 110 which is vertically downwardly provided near the front of the replenishment counter 10 (FIGS. 8 and 14). A switch projection 102 that is urged as described above, and a movable contact piece 101 that is provided so as to be able to press the switch projection 102 are provided. When the pressing portion 49 is lowered and the movable contact piece 101 is pressed down, the switch protrusion 102 is pressed and turned on (the state shown in FIG. 8). Conversely, when the pressing portion 49 is raised upward,
The switch protrusion 102 is urged and protrudes upward to be turned off (the state of FIG. 14).

Next, the prize ball replenishing device 6 having the above-described configuration.
The usage of is briefly explained. The prize ball supply device 6 is fixed to a frame 7 constituting a so-called island of a pachinko game store. In the award ball supply device 6, when the front frame 1b is closed, that is, in a playable state, the detection lever 60 is connected to the back wall 5a of the award ball tank 5 provided on the front frame 1b.
When the detection lever 60 is
Based on the rotation of the rotation lever 42,
The pressing lever 70 rotates. When the pressing lever 70 is rotated, the pressing claw 40 is disengaged from the stopper lever 20 of the replenishment counter 10, so that the sprocket 13 can be freely rotated. In addition, when the rotation lever 42 rotates, the plate portion 44 interlocked with the rotation lever 42 rotates, and the center of the ball passage 41 formed in the plate portion 44 and the center of the ball passage 12 of the replenishment counter 10 are moved. And the ball can pass. Further, when the plate portion 44 is rotated along with the rotation of the rotation lever 42, the ball introduction gutter 50 is rotated downward in conjunction with the plate portion 44, and the ball introduction gutter 50 is moved from the ball outlet 54 of the ball introduction gutter 50. The tip closing portion 55a of the closing plate 55 is removed, and the prize ball is supplied into the prize ball tank 5.

On the other hand, when the front frame is opened, the detection lever 60 is opened.
Is released, the detection lever 60 is rotated back by the bias of the coil spring 62, and the rotation lever 42
And the plate part 44 also returns and rotates. With the return rotation of the detection lever 60, the pressing lever 70 descends and the pressing claw 40
Presses the stopper lever 20 into the opening 24 of the supply counter 10. When the stopper lever 20 is pressed, a weight portion 22 provided on the stopper lever 20 is engaged with one of the ball engaging portions 14 of the sprocket 13. Therefore, the rotation of the sprocket 13 is prevented, and the passage of the ball in the ball passage 12 of the replenishment counter 10 is stopped (function by the first sealing means).

When the plate portion 44 returns and rotates, the center of the ball passage opening 41 formed in the plate portion 44 deviates from the center of the ball passage 12 in the replenishment counter 10, so that the ball cannot pass. The passage of the ball is also prevented at the outlet of the passage 12 (function by the second sealing means).

Further, when the plate portion 44 returns and rotates, the ball introduction gutter 50 rotates upward in conjunction with the plate portion 44, so that the ball flows into the ball passage tube portion 52 of the ball introduction gutter 50. And the ball outlet 54 of the ball inlet gutter 50
Is closed by the distal end closing portion 55a of the closing plate 55, so that introduction of a sphere through the sphere introduction gutter 50 becomes impossible (function by the third sealing means).

Therefore, when the front frame is in the open state, the flow of the ball is prevented from flowing down in a double or triple manner, and the flow of the ball from the ball supply gutter 2 is reliably prevented.

On the other hand, when the striking state is reached, the latching solenoid 90 may be excited. That is, when the latching solenoid 90 is excited, the plunger 90a
Is sucked, the striking lever 92 pivots downward, the striking claw 91 enters the opening 24 of the replenishment counter 10, and presses the stopper lever 20. Then, the weight portion 22 of the stopper lever 20 fits into the ball engaging portion 14 of the sprocket 13 to restrain the rotation of the sprocket 13. Therefore, the supply of the ball in the ball passage 12 of the replenishment counter 10 is blocked, and thereafter, the game becomes impossible.

Further, in this embodiment, the microswitch 100 operates according to the opening and closing of the front frame 1b. That is, when the front frame 1b is closed, the detection lever 60 rotates,
In response to the rotation, the rotation lever 42 and the pressing lever 70 associated therewith rotate. When the pressing lever 70 rotates, the pressing portion 49 is lifted up and disengaged from the movable contact piece 101 of the microswitch 100, so that the switch projection 102 is urged upward and the switch is turned off. Also, front frame 1
When the b is released, the pressing on the detection lever 60 is released, so that the detection lever 60 is returned and rotated by the bias of the coil spring 62, and the rotation lever 42 and the pressing lever 70 are released.
Also rotates back. When the pressing lever 70 returns and rotates, the pressing portion 49 descends to press the movable contact piece 101 of the microswitch 100, and the switch protrusion 102 is pressed to turn on the switch.

The above-mentioned micro switch on / off signal is sent to, for example, a central control room, and a lamp is displayed according to the signal.
The system is configured so that the clerk can immediately know whether or not b has been opened, and the system automatically starts video monitoring of the pachinko machine 1 immediately.

As described above, the prize ball replenishing device 6 having the detection lever 60 which operates according to the opening and closing of the front frame 1b is attached to the island-side frame 7, and the micro switch 100 is linked to the detection lever 60. Since the opening and closing of the front frame 1b can be detected by turning on and off the microswitch 100, there is no need to attach a door switch for opening / closing detection to the pachinko machine 1, and even if the pachinko machine 1 is replaced, the pachinko machine 1 remains in particular. The open / closed state of the front frame 1b can be detected without fine adjustment, and the open / closed state of the pachinko machine can be easily detected in a short time.

Even if the pachinko machine 1 is replaced, if the height adjustment between the prize ball supply device 6 on the frame side and the prize ball tank 5 on the new pachinko machine 1 becomes necessary,
Since the main body (base substrate 30) of the prize ball replenishing device 6 can be slid with respect to the fixed plate 8 attached to the frame 7,
The pachinko machine can be easily adjusted to the optimal height, and even if the height adjustment is required, the opening and closing of the pachinko machine can be easily detected in a short time.

Although the present invention has been described with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments, and can be appropriately implemented without changing the configuration described in the claims.

[0063]

As described above, according to the pachinko machine opening / closing detecting device of the present invention, the ball replenishing means having the position movable member which operates according to the opening and closing of the front frame is provided on each of the pachinko machines on the island facility side frame. The opening / closing detection means is linked to the position movable member, so that the opening / closing of the front frame can be detected by the output signal of the opening / closing detection means. There is no need to attach a switch, and even if the pachinko machine is replaced, it is possible to detect the opening and closing of the front frame without changing the pachinko machine, and without any special adjustments. become.
