As shown in FIGS. 10 and 12, a swing prevention pin 100 is provided in which the contact surface 85c of the first stopper 85 is substantially in contact with the contact surface 85c from the left side.

At the upper side of the notch 79 of the interrupted wall 75b, the shaft element 101 fixed to the case 72 has a 12th
As shown in the figure, the upper movement inhibiting piece 102 and the stop plate 103
are pivoted in parallel, and their vertical receiving surfaces 102a and 103a extend from the notch 79 into the ball passage 75 due to their own weight. The actuating plate 8 is placed on the lower surface of each of the inhibiting piece 102 and the stop plate 103 in a state that it abuts against the stop lever 104 on the back.
Notches 102b and 103b are formed at the upper end of the 9 to receive the protruding piece 89a provided integrally therein, and abutting edges 102c and 103c are formed on the rear side of each of them to contact the upper end of the protruding piece 89a. There is. Further, the stop plate 103 is provided with a connecting piece 105 that projects leftward from the upper portion.

The surface of the case 72 in contact with the substrate 22 has a 10th
As shown in the drawings and FIG. 12, an interlocking plate 107 is supported by a shaft 106, and a first connecting piece 108 and a second connecting piece 109 are separately connected to the eccentric portion of the interlocking plate 107. The second connecting piece 109 is connected to the connecting piece 105 of the stop plate 103, and the stop plate 103, the interlocking plate 107, the first connecting piece 108, etc. constitute a discharge prevention mechanism.

A ball extraction lever 110 corresponding to the upper part of the first stopper 85 and the second stopper 86 is attached to the back surface of the lower part of the case 72 by a shaft 111, and a lifting spring 112 is attached to the left side of the shaft 111 of the lever 110. is installed. The ball removal lever 110 is formed with a curved portion 110a that allows upward movement of the swing prevention pin 100, and further contacts the first contact edge 86c of the second stopper 86 from the right side and contacts the second stopper surface 86a. A locking protrusion 110b is formed to prevent obscene movement. or,
A restraining lever 1 corresponding to the first stopper 85 is attached to the shaft 88 of the second stopper 86 on the back side of the case 72.
13 is pivotally supported, and the lever 113 has an engaging edge 113a that engages with the contact surface 85c of the first stopper 85 as it swings counterclockwise in FIG.
is provided, and the lever 113 is connected to the connecting piece 114.
The lever is connected to the free end of the ball removal lever 110 to apply the elastic force of the pull-up spring 112.

A sensing piece 116 as a main detection means is attached to the bottom of the guide gutter 74 and is supported by a shaft 115, and a rotating plate supported by a shaft 117 is attached to the lower surface of the left side of the free end of the sensing piece 116. 118 is installed. The rotating plate 118 is axially connected to the sensing piece 116 at an eccentric position by a rod 119, and the left end of the first connecting piece 108 is axially connected to the eccentric position. A weight 122 is attached to the rear surface of the rotary plate 118, and the prize ball tank 71
When there is a replenishing ball X inside, rotate the rotary plate 118 counterclockwise in FIG.
When there is no plate 118, the plate 118 is rotated clockwise. Therefore, when the supplementary balls X run out of the prize ball tank 71, the rotary plate 118 is rotated clockwise and the sensing piece 116 is flipped up.

The prize ball discharging mechanism 73 configured in this way lowers the free end by the weight of the supplementary ball X flowing from the prize ball tank 71 and rides on the sensing piece 116 in the guide gutter 74, and the rod 119 moves the ball to the rotary plate 118. counterclockwise, the first connecting piece 108 rotates the interlocking plate 107 in the direction of the arrow in FIG. It is evacuated from the upper end of the passage 75. Therefore, the supplementary balls X flowing down the guide gutter 74 eliminate the receiving surface 102a of the upward movement inhibiting piece 102 and are lined up in the ball passage 75, and at the lower end of the ball passage 75, the stopper surface 85a of the first stopper 85 and the second stopper 86 within a narrow interval of the stopper surface 86a as shown in FIG.

On the other hand, the first stopper 85 has its abutting surface 85b in contact with the swing prevention pin 100 of the actuating plate 89 in the lowered position, and is prevented from rotating clockwise, and the second stopper 86 has the first contact edge 86c removed from the ball. lever 11
0 and is prevented from rotating counterclockwise, the lowest supplementary ball X in the ball passage 75 is held by the stopper surfaces 85a and 86a, preventing ball-to-ball contact. 2. The locking claw is aligned with the locking claw entrance/exit hole 81.

And when a safe ball occurs in a pachinko machine,
When the actuation plate 89 is pushed up by an actuation mechanism to be described later, the stop plate 103 and Since the notches 102b and 103b of the upward motion prevention piece 102 match the protrusion 89a of the actuation plate 89, the actuation plate 89 is moved upward under the rotation of the parallel links 90 and 91, and the locking pawl 99 is moved upward. As shown in FIG. 14, the locking claw protrudes into the ball passage 75 from the locking claw inlet/outlet hole 81 to prevent the replenishment ball X above the tip of the claw from flowing down.

On the other hand, while the actuating plate 89 is rising as described above, the swing prevention pin 100 moves upward together with the actuating plate 89 and comes off the stopper surface 85a of the first stopper 85 as shown in FIG. The stopper 85 is rotated clockwise by the weight of the replenishment balls X acting on the surface 85a, and releases all of the replenishment balls X below the tip of the locking pawl 99 downward.

The discharge is rapid and ends when the actuating plate 89 is about to move down after being raised, and the first stopper 85 automatically returns to the position shown in FIG. Immediately before the supporting claw 99 retreats its toe into the locking claw entrance/exit hole 81, the swing prevention pin 100 lowers and engages with the contact surface 85c.
Immediately after that, the locking pawl 99 is inserted into the entrance/exit hole 8.
1 and loses the locking action of the upper replenishment ball X by the toe, so the replenishment ball X again descends until it hits the first and first stopper surfaces 85a and 86a. With the above steps, the discharging of the prize balls and the replenishment of the ball passage 75 are completed.

Although the number of balls between the downstream end of the toe of the locking pawl 99 and the first and second stopper surfaces 85a and 86a is always constant, the locking pawl 99 can be connected to any shaft support 98 of the actuating plate 89. The number of prize balls to be released can be freely changed by replacing it with , or by setting it from the beginning.

Further, when the replenishment balls X riding on the sensing piece 116 of the guide gutter 74 run out, that is, when the replenishment balls X in the prize ball tank 71 run out, the rotary plate 118 is rotated clockwise by the weight 122 and repels the sensing piece 116. At the same time, the stop plate 103 is rotated as shown by the chain line in FIG. 10 via the first connecting piece 108 and the interlocking plate 107. As a result, when the receiving surface 103a of the stop plate protrudes into the upper end 77, the actuating plate 89
9a hits the abutting edge 103c of the stop plate 103 and does not substantially rise. Therefore, the swing prevention pin 100 remains engaged with the contact surface 85c of the first stopper 85, and the release of the prize ball is interrupted.

Furthermore, if there is no ball in the ball passage 75,
The upward movement inhibiting piece 102 allows the receiving surface 102a to advance into the ball passage 75 due to its weight balance, and at the same time, the abutting edge 102c is pushed against the locking protrusion 89 of the actuating plate 89.
A is brought into contact with the actuating plate 89, thereby restraining the upward movement of the actuating plate 89 and preventing the ejecting operation of the prize ball.

Furthermore, when the end of the ball extraction lever 110 is momentarily lifted using a solenoid or manually at the end of the workday, the first contact edge 86c of the second stopper 86 comes off the locking protrusion 110b of the ball extraction lever 110. The stopper 86 is rotated counterclockwise by the weight of the supplementary ball X acting on the stopper surface 86a.
Balls remaining in the ball passage 75, guide gutter 74, prize ball tank 71, etc. are discharged to the ball removal passage 120. At this time, the restraining lever 113 is interlocked by the connecting piece 114 to bring the engaging edge 113a of the lever 113 into contact with the contact surface 85c of the first stopper 85, thereby preventing the clockwise rotation of the first stopper 85. This protects the swing prevention pin 100. Even if the ball extraction lever 110 is released from its lifting position while the ball is being extracted, the elasticity of the lifting spring 112 will cause the locking protrusion 110b to close.
Since the first stopper 85 contacts the second contact edge 86d of the second stopper 86, the first stopper 85 will not rotate back clockwise under its own weight. When the ball removal lever 110 is lifted again after the ball removal is completed, return rotation is automatically performed to make the first stopper surface 85a vertical.

The ball locking lever 121 provided above the lower end of the guide trough 74 is tilted in the direction of the arrow in FIG. It is designed to prevent the supply of supplementary balls X.

Next, an operating mechanism for moving the operating plate 89 of the prize ball release mechanism 73 upward to operate the mechanism 73 will be described.

As shown in FIG. 17, a prize ball discharge path 131 is provided facing the terminal end of the prize ball discharge mechanism 73, and a prize ball discharge port 132 is transparently provided in the base plate 22 at the terminal end of the discharge path 131. The prize balls ejected from the ejection mechanism 73 reach the upper tray 18. In addition, the prize ball release path 131 and the prize ball passage hole 24
A prize ball lead-out path 133 is formed between the upper plate 1
8 and the terminal part of the prize ball discharge path 131 is filled with prize balls, the overflowing prize balls are sent to the prize ball outlet path 133.
The ball passes through the prize ball passage hole 24 and reaches the lower plate 19.

Incidentally, 134a, 134b, and 134c indicate the levels at which the balls flowing down the prize ball discharge path 131 and the prize ball derivation path 133 collide with each other to emit an impact sound to notify the release of the prize ball.

As shown in FIGS. 1 and 9, the front surface of the board 22 has a diagonal safe on which a safe ball received in a safe ball receiving opening (not shown) of a chuck car or the like on a game board 23 rolls. A ball passage 135 is formed.

As shown in FIG. 17, a safe ball outlet 136 corresponding to the terminal end of the safe ball passage 135 is opened near the prize ball outlet 132, and the safe ball is transferred from the safe ball receiving port to the safe ball outlet 136. It is guided from the outlet 136 to a lower outlet path 137 .

As shown in FIGS. 18 and 20, the substrate 22
A gear motor 138 fixed to the front surface of the board 22 has a motor shaft 138a protruding toward the rear surface of the board 22, and a circular rotating member 13 located at the end of the safe ball guide path 137 is mounted on the motor shaft 138a.
9 is fixed. This rotating member 139
As shown in FIG.
40, and a protrusion 141 protruding from one side of the disc part 140.
Claw portions 140a are formed at positions separated by 180 degrees, and semicircular accommodating portions 141a are cut out at positions 180 degrees apart from each other on the outer periphery of the protrusion 141, and the accommodating portions 141a lead out the safe ball. When facing the path 137, the safe ball falls and is accommodated in the accommodation portion 141a. Further, the gear motor 138 is always inputted by turning on the power switch (not shown) of the pachinko machine, and the rotation of the gear motor 138 causes the rotating member 139 to rotate in the direction of arrow P in FIG. .

Immediately above the right side of the rotating member 139 is a shaft 14.
A circular discharge actuating body 143 is rotatably supported by 2, and an engaging piece 143a and a connecting protrusion 143b are protruded from the inner surface thereof, and the connecting protrusion 1
43b is connected to the lower end of the operating plate 89 of the prize ball release mechanism 73 via a connecting rod 144.
Then, when the rotating member 139 is rotated in the direction of arrow P from the position shown in FIG. 17 in a state in which the safe ball is accommodated in the accommodating portion 141a of the rotating member 139, the safe ball in the accommodating portion 141a is moved outward. The protruding portion engages with the engagement piece 143a of the ejection actuation plate 143, and the ejection actuation plate 143 is rotated by a predetermined amount, and this operation is transmitted via the connecting rod 144 to the prize ball ejection mechanism 7.
The ball is transmitted to the operating plate 89 of No. 3, and the above-described prize ball release operation is performed.

In this case, the engagement piece 143a is close to the accommodating portion 141a at the position shown in FIG.
39 rotates, the safe ball in the housing portion 141a and the engagement piece 143a immediately engage with each other, and the discharge actuating body 143 is immediately rotated. In addition, storage section 1
The safe ball in 41a falls downward after being disengaged from the engagement piece 143a, and after falling, the discharge actuating body 1
43 immediately returns to the position shown in FIG.

A lock piece 146 is swingably supported above the rotating member 139 by a shaft 145, and the claw portion 1 of the disk portion 140 is attached to the lower end of the lock piece 146, as shown in FIG.
A hook portion 146a that can engage with the safe ball 40a is formed, and a release portion 146c that is interposed in the safe ball lead-out path 137 and comes into contact with the safe ball is formed at the lower right side. Also, lock piece 14
An arm 146b protrudes leftward from the upper end of 6.

Below the arm 146b is a solenoid 14.
7 is fixed, and by exciting it, the core 147a
is projected upward. The solenoid 147 is energized when the operating handle 20 is not operated. Therefore, under normal conditions when the pachinko machine is not in use, the solenoid 147 is energized and the core 14 is energized.
7a protrudes upward, thus its core 147a
comes into contact with the arm 146b of the lock piece 146 from below to rotate the lock piece 146 and position the hook portion 146a at its lower end out of the engagement range with the claw portion 140a. Also, pachinko machines are used,
When the operating handle 20 is operated, the solenoid 147 is demagnetized, the core 147a retracts downward, and the lock piece 146 is placed in a hanging position due to its own weight. In this case, the hook portion 146a is located within the engagement range with the claw portion 140a, and the hook portion 1
46a and one claw portion 140a engage, rotation of the rotating member 139 is prevented at a position where one of the housing portions 141a faces the safe ball outlet path 137.

Now, when the safe ball is guided into the safe ball outlet path 137 via the safe ball passage 135, the safe ball comes into contact with the release part 146c of the lock piece 146, and the lock piece 146 is rotated counterclockwise. After being moved, it is accommodated in the accommodating portion 141a of the rotating member 139. By rotating the lock piece 146, the engagement between the hook piece 146a of the lock piece 146 and the claw portion 140a of the rotating member 139 is released, and the rotating member 139 containing the safe ball is immediately rotated. Then, the operating body 143 is rotated using the same safe ball, and the prize ball release mechanism 73 is immediately activated via the rod 144.

When the rotating member 139 rotates 180 degrees, the claw portion 140a of the rotating member 139 engages with the hook portion 146a of the lock piece 146, which has returned to the hanging position, so that the rotating member 139 moves to the next safe ball. The rotation is stopped until it is accommodated in the accommodation portion 141a. Alternatively, the lock piece 146 or the like may not be provided, and the safe ball that has passed through the safe ball passage 135 may be guided directly onto the rotating member 139 through the safe ball outlet path 137 and sent into the accommodating portion 141a.

A sensing member 149 is rotatably supported at its intermediate portion by a shaft 148 near the prize ball lead-out path 133, and one end thereof is connected to the prize ball lead-out path 133.
It has come to form part of the This sensing member 149 is normally elastically held with one end in contact with a stopper 151 by the spring force of a spring 150, and the one end protrudes toward the outlet path 133 side. A blocking rod 152 is supported at the base end of the sensing member 149, and when the sensing member 149 is rotated to the position shown in FIG. It enters into the safe ball lead-out path 137 and blocks the passage of the safe ball. Therefore, normally, the spring force of the spring 150 causes one end of the sensing member 149 to protrude into the winning ball outlet path 133, and the tip of the blocking rod 152 to retreat from the safe ball outlet path 137, thereby removing the safe ball from the safe ball accommodation section. 14
Falling to 1a is allowed. Furthermore, when the lower tray 19 and the prize ball outlet path 133 are filled with prize balls, the overflowing prize balls rotate the sensing member 149 to the position shown in FIG. The ball enters the lead-out path 137 and prevents the safe ball from falling into the housing portion 141a.

Therefore, the rotating member 139 is not rotated from now on, and the ejection actuator 143 is also not rotated, and the ejection operation of the prize ball by the prize ball ejecting device 73 is stopped.

Next, a stop operation mechanism for operating the ball supply stop mechanism 60 by rotating the linking lever 64 of the ball supply stop mechanism 60 will be described.

As shown in FIG. 21, the upper end of the connecting rod 161 is connected to the rear surface of the rotary plate 118 so as to correspond to the attachment position of the rod 119, and the rotary plate 118 allows the weight 122 to move from the position shown by the two-dot chain line. By being deflected to the position shown by the solid line, when the ball is rotated, that is, when the supplementary ball X in the prize ball tank 71 runs out and is rotated in the direction of the arrow, it is moved upward to the position shown by the solid line. The operating lever 162 is rotatably supported by a shaft 163, one end of which is rotatably connected to the lower end of the connecting rod 161, and the other end connected to an interlocking link 164. The interlocking link 164 has a shaft pin 1 at its tip.
65 is provided, and its shaft pin 165 is rotatably connected to the connection hole 64a of the connection lever 64.

Then, when the ball supply stop mechanism 60 is in the solid line position in FIG. is rotated to the position shown by the two-dot chain line, and the rotating plate 118 is rotated in the opposite direction of the arrow. This rotation causes the connecting rod 161 to move downward, causing the actuating lever 162 to rotate clockwise and, via the interlocking link 164, to rotate the linking lever 64 counterclockwise about the shaft 63.

As the linkage lever 64 rotates counterclockwise,
The display lever 44 is rotated about the shaft 48 to the position indicated by the two-dot chain line via the connecting link 67, the interlocking lever 62, and the connecting lever 45. As a result, the supply hole 17b is opened and the game ball can be supplied to the ball hitting section. Therefore, the player can perform a ball hitting operation.

On the other hand, when there are no more supplementary balls X in the prize ball tank 71, the weight 122 rotates from the two-dot chain line position to the solid line position in FIG. On the contrary, move it upwards. Along with this upward movement, the operating lever 1
62, the linking lever 64, and other members perform operations opposite to those described above, and rotate the display lever 44 from the two-dot chain line position in FIG. 21 to the solid line position. As a result, the supply hole 17b is closed by the opening/closing portion 44b.

On the other hand, in this series of operations, that is, as the rotating plate 118 is rotated in the direction of the arrow,
Since the stop plate 103 of the prize ball release mechanism 73 is rotated as shown by the chain line in FIG. 10, the release of the prize ball is immediately interrupted as described above.

In this way, when there is no more supplementary ball X in the prize ball tank 71 and the rotary plate 118 is rotated, the stop plate 103 is rotated based on the rotation of the rotary plate 118. The receiving surface of this stop plate 103 is the upper end 77.
As the locking protrusion 89a of the actuating plate 89 collides with the abutting edge 103c of the stop plate 103 and the actuating plate 89 does not rise, the ejection prevention operation of the prize ball ejecting device is locked. be done. on the other hand,
Based on the rotation of this rotating plate 118, the connecting rod 161
By rotating the operating lever 162 through the
7b, the supply of game balls to the ball hitting section is blocked.

Therefore, as soon as there are no more supplementary balls in the prize ball tank 71, the discharging operation of the prize ball discharging device is stopped, and in synchronization with the discharging operation, the supply of game balls to the ball hitting position is immediately stopped, and the ball is discharged. To prevent a game from being continued even though there are insufficient or no prize balls to play.

Note that the present invention is not limited to the above-mentioned embodiment, and for example, the rotary plate 118 as a moving member may be used.
Instead, the sensing piece 116 is always urged to be in the upper position by an elastic member, and when there is a replenishing ball X in the tank 71, the weight of the refilling ball X is used to
The sensing piece 116 is configured to be prevented from rotating, and on the other hand, to be rotated by an elastic member when there is no supplementary ball X. Based on the rotational movement of the sensing piece 116, the stop plate 103 and the connecting rod 161 may be rotated and moved upward.

As described in detail above, in this invention, the prize ball release mechanism, which is connected to the prize ball tank through the guide gutter, operates to release the prize balls based on the safe balls that have entered the chucker, etc., and a predetermined number of prize balls are released. In the pachinko machine, a detection means for detecting the absence of replenishment balls in the prize ball tank is disposed in the guide gutter, and in response to the detection operation of the detection means, the prize ball release mechanism is activated. The prize ball tank is equipped with a release prevention mechanism that prevents the release operation and a ball supply stop mechanism that stops the supply of game balls from the upper tray to the ball hitting position in response to the detection operation of the detection means. As soon as there are no more supplementary balls in the game, the supply of game balls to the ball hitting position is immediately stopped in conjunction with the release prevention operation of the prize ball release device, and the game continues even though there are insufficient or no prize balls to be released. This has the effect of being able to prevent such inconveniences from occurring.

In particular, when a shortage of replenishment balls is detected (when the balls are out), a configuration that prevents the release of prize balls and a configuration that stops the supply of game balls are activated by one detection means (sensing piece) that detects a shortage of replenishment balls. Therefore, if the game is interrupted due to a lack of replenishment balls (when the balls run out), the ejection operation of the prize balls will stop and the ball will no longer be able to be fired, so there will be no replenishment balls in the prize ball tank. The player can clearly recognize the correspondence between the stoppage of prize ball release and the interruption of play due to the age, and this has the effect of not giving the player any discomfort.
