Is provided with an engaging edge 113a for engaging with
13 is connected to the free end of the ball-removing lever 110 by a connecting piece 114 so that the pull-up spring 112 can exert the elastic force.

On the trough bottom of the guide trough 74, there is attached a sensing piece 116 which is a replenishment ball breakage detecting means pivotally supported by a shaft 115, and the lower end of the free end of the sensing piece 116 is attached to the shaft 1.
A rotary plate 118 supported by 17 is attached. The rotating plate 118 is axially connected to the sensing piece 116 by a rod 119 at an eccentric position, and the left end of the first connecting piece 108 is axially connected to the eccentric position. Weight 122
Is attached to the rear surface of the rotary plate 118, and when there is a supplementary ball X in the prize ball tank 71, the rotary plate 118 is rotated counterclockwise in FIG. Sometimes, the plate 118 is rotated clockwise. Therefore, when the replenishment ball X is no longer in the prize ball tank 71, the rotary plate 118 is rotated clockwise, and the sensing piece 116 is flipped up.

When the supplementary ball X flowing from the prize ball tank 71 rides on the sensing piece 116 in the guide trough 74, the prize ball discharging mechanism 73 configured as described above lowers the free end by the weight, and the rod 1
The rotating plate 118 is rotated counterclockwise by 19, the interlocking plate 107 is rotated by the first connecting piece 108 in the arrow direction of FIG. 12, and the connecting piece 105 of the stop plate 103 is pulled up by the second connecting piece 109. The receiving surface 103a is retracted from the upper end of the ball passage 75. For this reason, the supplementary balls X flowing down the guide trough 74 are arranged in a row in the ball passage 75 excluding the receiving surface 102a of the upward movement inhibiting piece 102, and the stopper surface 85a of the first stopper 85 and the second stopper at the lower end of the ball passage 75. As shown in FIG. 13, the rider 86 rides within the narrow space of the stopper surface 86a.

On the other hand, the first stopper 85 has an abutting surface 85b.
Is contacted with the rocking prevention pin 100 of the operating plate 89 in the lowered position to prevent the clockwise rotation, and the second stopper 86
Is the locking protrusion 1 of the lever 110 for removing the ball from the first contact edge 86c.
Since it is locked to 10b and prevented from rotating clockwise,
The lowest refill ball X in the ball passage 75 is the stopper surface 85.
It is held by a and 86a, and the contact portion between the balls is made to coincide with the locking claw insertion / removal hole 81.

Then, a safe ball is generated in the pachinko machine ,
When the actuating plate 89 is pushed up by the actuating mechanism described later, the upper end 77 of the ball passage 75 is filled with the replenishing ball X and the sensing piece 116 is pushed down by the ball weight. notch 102b of the upward movement prohibition piece 102, since 103b meets the protrusion 89a of the operation plate 89, work rotation plate 89 is moved upward under the rotation of the parallel link 90 and 91, the engaging支爪99 As shown in FIG. 14, it projects into the ball passage 75 from the locking claw insertion / removal hole 81 to prevent the replenishment ball X above the tip of the claw from flowing down.

On the other hand, when the operation plate 89 moves upward as described above, the rocking prevention pin 100 moves upward together with the operation plate 89 and comes off from the stopper surface 85a of the first stopper 85 as shown in FIG. , The stopper surface 85
The stopper 85 is rotated in the clockwise direction by the weight of the replenishing ball X acting on a, and all the replenishing ball X below the toe of the engaging claw 99 is discharged downward.

The discharge is fast and ends by the time when the operating plate 89 moves up and then goes down, the first stopper 85 automatically returns to the position shown in FIG.
Engagement supporting pawl 99 by the lowering of the operating plate 89 is lowered oscillation preventive pin 100 immediately before reject toe locking pawl and out holes 81 for engagement with the contact surface 85c. Immediately after that, the supporting claw 99 retracts into the entrance / exit hole 81 and loses the supporting function of the upper replenishing ball X by the tip of the toe, so that the replenishing ball X again reaches the first and second stopper surfaces 85a and 86a. It descends until it hits. With the above, the discharge of the prize balls and the replenishment of the ball passage 75 are completed.

Although the number of balls from the downstream of the tip of the support claw 99 to the first and second stopper surfaces 85a and 86a is always constant, the support claw 99 can be attached to any of the operating plates 89. The number of prize balls to be discharged can be freely changed by replacing the shaft supporting portion 98 or by setting it from the beginning.

The supplementary ball X on the sensing piece 116 of the guide gutter 74 is lacking, that is, the supplemental ball X in the prize ball tank 71.
Then, the rotating plate 118 is rotated clockwise by the weight 122 to repel the sensing piece 116, and the stop plate 103 is moved to the first position via the first connecting piece 108 and the interlocking plate 107.
Rotate as shown by the chain line in FIG. As a result, when the receiving surface 103a of the stop plate projects into the upper end 77, the operating plate 89
The locking projection 89a hits the abutting edge 103c of the stop plate 103 and does not substantially rise. Therefore, the rocking prevention pin 100 remains engaged with the contact surface 85c of the first stopper 85, and the discharge of the prize ball is interrupted. Further, when there is no ball in the ball passage 75, the upward movement prohibiting piece 10
2 is a receiving surface 1 in the ball passage 75 due to its weight balance.
02a is advanced, and at the same time, the abutting edge 102c is moved to the operating plate 89.
The engaging projection 89a is brought into contact with the operating plate 89 to restrain the upward movement of the operating plate 89 and prevent the prize ball releasing operation.

When the end of the ball-removing lever 110 is momentarily lifted by a solenoid or manually at the end of work,
The first contact edge 86c of the second stopper 86 is disengaged from the locking projection 110b of the ball removing lever 110, and the stopper 86 rotates counterclockwise by the weight of the supplementary ball X acting on the stopper surface 86a. The residual balls in the ball passage 75, the guide gutter 74, the 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 rotating the stopper 85 in the clockwise direction. It blocks and protects the rocking prevention pin 100. While removing the ball-removing lever 110,
Even if it is released from lifting, at that time, since the locking projection 110b contacts the second contact edge 86d of the second stopper 86 by the elastic force of the pulling spring 112, the first stopper 85 does not turn back clockwise by its own weight. . When the ball-removing lever 110 is lifted again after the ball-removing is completed, the first stopper surface 85a is automatically returned to the vertical direction for rotation.

The ball stopper lever 121 provided above the lower end of the guide gutter 74 is tilted in the direction of the arrow in FIG. 10 so that the locking claw 121a faces the upper end of the ball passage 75 and enters the ball passage 75. The supply of the replenishing ball X of the above is blocked.

When the rotating member 139 is rotated in the direction of the arrow P from the position shown in FIG. 17, the outward protrusion of the safe ball inside the accommodating portion 141a engages with the engaging piece 143a of the releasing actuating body 143 to perform the releasing operation. The body 143 is rotated by a predetermined amount, and its operation is transmitted to the actuation plate 89 of the prize ball discharging mechanism 73 through the connecting rod 144, and the prize ball discharging operation described above is performed.

In this case, the engaging piece 143a is close to the accommodating portion 141a at the position shown in FIG.
When 9 rotates, the safe ball inside the accommodating portion 141a and the engaging piece 143a immediately engage with each other, and the discharge actuating body 143 immediately rotates. The safe ball in the accommodating part 141a falls off after being disengaged from the engaging piece 143a, and after the drop, the discharge actuating body 143 immediately returns to the position shown in FIG.

A lock piece 146 is swingably supported by a shaft 145 above the rotating member 139, and a lower end of the lock piece 146 is engageable with a claw portion 140a of the disc portion 140 as shown in FIG. A hook portion 146a is formed, and a release portion 146c that is interposed in the safe ball lead-out path 137 and abuts on the safe ball is formed on the lower right side. An arm 146b is protruded from the upper end of the lock piece 146 toward the left side.

A solenoid 147 is fixed below the arm 146b, and the core 147a is projected upward by being excited. The solenoid 147 is excited when the operation handle 20 is not operated. Therefore, when the pachinko machine is not used normally, the solenoid 147 is excited and the core 147a projects upward, so that the core 147a abuts the arm 146b of the lock piece 146 from below and rotates the lock piece 146. The hook portion 146a at the lower end is moved outside the engagement range with the claw portion 140a. Also, a pachinko machine is used,
When the operating handle 20 is operated, the solenoid 14
7 is demagnetized, the core 147a is recessed downward, and the lock piece 146 is arranged at the hanging position by its own weight. In this case, the hook portion 146a is located in the engagement range with the claw portion 140a, and when the hook portion 146a and one of the claw portions 140a are engaged, one of the accommodating portions 141a is led out of the safe ball. The rotation of the rotating member 139 is blocked at the position facing the path 137.

And now the safe ball is the safe ball passage 135
When guided into the safe sphere derivation path 137 via, the safe sphere comes into contact with the release portion 146c of the lock piece 146,
After rotating the lock piece 146 in the counterclockwise direction, the lock piece 146 is housed in the housing portion 141 a of the rotating member 139. Lock piece 14
When the lock piece 146 of the lock piece 146 is rotated,
The engagement between 46a 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 actuating body 143 is rotated by the safe ball, and immediately the prize ball releasing mechanism 73 is operated via the rod 144.

When the rotary member 139 rotates 180 degrees, the hook 146a of the lock piece 146 and the claw 140a of the rotary member 139, which have returned to the hanging position again, engage with each other, so that the rotary member 139 is moved to the next position. The rotation of the safe ball is stopped until it is housed in the housing portion 141a. The locking piece 146 and the like are not provided, and the safe sphere that has passed through the safe sphere passage 135 passes through the safe sphere lead-out path 137 and the rotating member 13.
9 may be directly guided to the container 9 and fed into the housing portion 141a.

A shaft 148 is provided in the vicinity of the prize ball lead-out path 133.
Thus, the sensing member 149 is rotatably supported at its intermediate portion, and one end thereof forms a part of the prize ball lead-out path 133. The sensing member 149 is normally elastically held by the spring force of the spring 150 in a state where one end of the sensing member 149 is in contact with the stopper 151, and one end of the sensing member 149 projects toward the lead-out path 133 side. A blocking rod 152 is supported at the base end of the sensing member 149, and
When 49 is rotated to the position shown in FIG. 19, the tip end of the blocking rod 152 enters the safe ball lead-out path 137 directly above the rotating member 139 to block the safe ball path. It has become. Therefore, normally, the spring force of the spring 150 causes one end of the sensing member 149 to project into the prize ball lead-out path 133 and the tip of the blocking rod 152 to retreat from the safe ball lead-out path 137. Is allowed to fall. When the prize balls are filled in the lower plate 19 and the prize ball outlet path 133, the sensing member 149 is rotated to the position shown in FIG. It advances into the lead-out path 137 to prevent the safe ball from falling into the accommodating portion 141a.

Therefore, the rotating member 139 is not rotated thereafter, and the discharge actuating member 143 is not rotated, so that the prize ball discharging operation by the prize ball discharging device 73 is stopped. Next, the linkage lever 64 of the sphere supply stopping mechanism 60 described above.
A stop operation mechanism for rotating the mechanism 60 to operate the mechanism 60 will be described.

As shown in FIG. 21, the connecting rod 161 has its upper end 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 has two weights 122. By being displaced from the chain line position to the solid line position, the rotation, that is, the refill ball X in the prize ball tank 71.
When it disappears and is rotated in the direction of the arrow, it is moved up 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 of which is connected to an interlocking link 164.
The interlocking link 164 is provided with a shaft pin 165 at the tip thereof, and the shaft pin 165 is connected to the connecting hole 6 of the connecting lever 64.
It is rotatably connected to 4a.

When the ball supply stopping mechanism 60 is in the position shown by the solid line in FIG. 21, that is, when the supplementary ball X is not in the prize ball tank 71, the supplementary ball X is stored in the prize ball tank 71.
When the weight is replenished, the rotating plate 118 is rotated in the direction opposite to the arrow as the weight 122 is rotated to the position indicated by the chain double-dashed line. By this rotation, the connecting rod 161 is moved downward,
Rotate the operating lever 162 clockwise to move the interlocking link 16
The linkage lever 64 is rotated in the counterclockwise direction about the shaft 63 via the shaft 4.

With the counterclockwise rotation of the linkage lever 64, the display lever 44 is rotated about the shaft 48 to the two-dot chain line position via the connecting link 67, the interlocking lever 62 and the connecting lever 45. . Thereby, the supply hole 17
When b is opened, the play ball can be supplied to the hitting portion.
Therefore, the player can operate the ball.

On the contrary, when the replenishing ball X is no longer in the prize ball tank 71, the weight 122 is rotated from the position shown by the dashed line in FIG. 21 to the position shown by the solid line to rotate the rotary plate 118 in the direction of the arrow to connect the connecting rod. In contrast to the above, 161 is moved upward. With this upward movement, the operating lever 162 and the linkage lever 64
Each member such as performs the operation opposite to the above, and the display lever 44
21 is rotated from the position indicated by the dashed-dotted line in FIG. 21 to the position indicated by the solid line. 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 rotary plate 118 is rotated in the direction of the arrow, the stop plate 103 of the prize ball discharging mechanism 73 is rotated as shown by the chain line in FIG. As described above, the release of prize balls is immediately stopped.

In this way, the supplementary ball X is placed in the prize ball tank 71.
When the rotary plate 118 is rotated without the above, the stop plate 103 is rotated based on the rotation of the rotary plate 118. The receiving surface of the stop plate 103 is projected into the upper end 77, and the locking projection 89a of the operating plate 89 is fixed to the stop plate 103.
With the fact that the operating plate 89 does not move up by hitting the abutting edge 103c, the discharge blocking operation of the prize ball discharging device is locked. On the other hand, by rotating the operating lever 162 via the connecting rod 161 based on the rotation of the rotary plate 118, the display lever 44 is also rotated to close the supply hole 17b, so that the ball hitting the game ball is hit. Supply is blocked.

Therefore, at the same time as the supplementary balls in the prize ball tank 71 are exhausted, the discharging operation of the prize ball discharging device is stopped, and the supply of the play ball to the hitting position is immediately stopped in synchronization with the discharging operation. It is possible to prevent the game from continuing even if the prize balls to be discharged are insufficient or not at all.

It should be noted that the present invention is not limited to the above embodiment, and for example, instead of the rotary plate 118 as a moving member, the sensing piece 116 is biased by an elastic member so as to always rotate to the upper position. Then, when the replenishment sphere X is in the tank 71, the rotation of the sensing piece 116 is blocked by the weight of the replenishment sphere X, and conversely, when the replenishment sphere X is not present, the sensing piece 116 is rotated by the elastic member. And this sensing piece 116
Based on the rotational movement of the stop plate 103 and the connecting rod 161
May be rotated and moved upward.
