Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ball removing device for a pachinko machine.

[Prior Art] Conventionally, as a ball removing device for a pachinko machine, for example, as described in Japanese Utility Model Publication No. 56-45662,
The opening/closing lever provided on the ball extraction opening can be opened and closed by sliding a slider, or the lid body provided on the ball extraction opening can be locked with a locking plate as described in Publication No. 8865/1986. There are known devices that open and close by synergistic action.

[Problems to be solved by the invention] Among the conventional techniques, the former requires a large space for sliding the long slider, and also requires a large space for sliding the slider and for preventing it from slipping out. The structure is complicated, such as the formation of a locking part, and furthermore, if dirt or the like adheres to the sliding guide groove, the movement of the slider becomes poor and there is a problem in that it becomes difficult to remove the ball.

In addition, in the latter case, the lid body is maintained in an open state with respect to the ball extraction opening by the balance between the weight of the lid body itself, the pressing force of the ball being removed, and the biasing spring of the locking plate that locks the lid body. Because of this, if some kind of impact is applied while the ball is being removed and the balance is disrupted, or if a situation occurs where the ball is not applying enough pressure against the lid, the lid may be damaged while the ball is being removed. There was a problem in that the body was locked to the locking plate and the ball extraction opening was blocked.

[Means for Solving the Problems] The present invention was made in view of the above-mentioned problems, and consists of opening a ball extraction port at the bottom of the guide gutter that communicates with the prize tank and installing a movable bottom plate in the ball extraction hole. Attached to the shaft,
The movable bottom plate is pivoted downward by the weight of the balls resting on its upper surface to open the ball extraction opening, and when released from the ball weight, rotates back to a position where it closes the ball extraction opening with its own weight. Further, an engagement lever is provided below the movable bottom plate, one end of which is rotatably supported, and which engages the movable bottom plate and locks the ball in a position that closes the ball opening. An actuation plate is provided on the side of the pachinko machine that rotates downward against the biasing force of a spring due to a pressing action from the front of the pachinko machine, and the actuation plate and the engagement lever are connected to each other. The movable bottom plate is disengaged by rotating the engagement lever.

[Operation] The engagement lever rotates due to the downward rotation of the actuation plate. As the engagement lever rotates, the movable bottom plate is disengaged from the engagement lever, and the movable bottom plate becomes free, thereby opening the ball extraction opening and allowing the ball to be extracted.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. Fig. 1 is a back view of the pachinko machine, where 1 is a game board, 2 is a mechanism plate that is removably arranged on the back of the game board 1, 3 is a prize tank attached above it, and 4 is a prize tank. The prize balls within 3 are released by the prize ball release device 5.
Shows the guide gutter leading to.

Fig. 2 is a perspective view of the ball removal device according to the present invention, Fig. 3 is a partially sectional front view for explaining the action, and Fig. 4 is a side view for explaining the action.
numeral 7 indicates a ball extraction hole provided at the bottom of the guide trough 4; 7 indicates a ball extraction trough extending below the ball extraction hole 6; and 8 is attached to the upstream edge of the ball extraction hole 6 by a shaft 9. The movable bottom plate 8 has a substantially dogleg shape, and the movable bottom plate 8 is provided so as to be rotated downward by the weight of the ball resting on its upper surface to open the ball extraction opening 6. When the weight 11 is attached and released from the weight of the ball, the acting force of the weight 11 causes the ball to return to the position where it closes the ball extraction opening 6 as shown by the solid line in FIG. 12 is an engagement lever located below the movable bottom plate 8, one end of which is rotatably supported on a shaft 13 protruding from the mechanism plate 2, and the other end is attached to the lower end of the engagement piece 10 of the movable bottom plate 8 A locking protrusion 15 for contact engagement is provided.

Reference numeral 16 denotes an actuating plate disposed in the gap between the game board 1 and the engaging lever 12, and the shaft 13 of the engaging lever 12 is inserted into the supporting portion 17 that projects laterally of the mechanism plate 2.
The lower bent portion is pivotally supported on a horizontal axis 18 perpendicular to the operating plate 16, and the actuating plate 16 is provided with a connecting pin 19 that projects rearward and a wide push piece 20 at the top.
are inserted into the through hole 21 formed in the locking protrusion 15 of the engagement lever 12 and connected, and the push piece 2
0 is positioned corresponding to the pin hole 23 bored in the pachinko machine front frame 22. Further, the actuating plate 16 is urged to rotate forward by a spring 24 wound around the horizontal shaft 18 and is normally at the position shown by the solid line in FIG. The engaging piece 10 is engaged with the engaging protrusion 15 of the lever, and the movable bottom plate 8 is restrained in a position where the ball opening 6 shown in solid line in FIG. 3 is closed.

In the ball extracting device having the above configuration, in order to extract the prize balls from the prize ball tank, a pin or the like is inserted into the pin 23 of the front frame 22 from the front of the pachinko machine and the push piece 20 of the operating plate 16 is pushed. This causes the actuating plate 16 to move to the fourth position.
The engaging piece 1 of the movable bottom plate 8 is rotated downward as shown by the chain line in the figure, and the engagement lever 12 is moved down by the connecting pin 19 as shown in the chain line in FIG.
0. Therefore, the movable bottom plate 8 is in a free state, and due to the weight of the balls on the upper surface, it rotates about the shaft 9 as a fulcrum as shown by the chain line in Figure 3, opens the ball extraction port 6, and drops the prize balls into the ball extraction channel 7. It can be removed.

After the ball removal is completed, a pin or the like is inserted into the pin hole 23 again, the operating plate 16 is rotated downward, and the engagement lever 12 is moved downward, so that the movable bottom plate 8 returns to the position shown by the solid line in FIG. 3 under its own weight. , and the actuating plate 1
By releasing the pressure of 6, the engagement lever 12
also returns to the solid line position in FIG. 3 to restrain the movable bottom plate 8.

[Effect of the invention] As explained above, according to the invention, the actuating plate 1
By pressing 6 and rotating the engagement lever 12, the movable bottom plate 8 can be easily released from the restraint and the ball can be removed.Therefore, unlike the conventional device, the ball can be removed by sliding the slider. It has a simpler structure and can be expected to operate more reliably.

In addition, the movable bottom plate that opens and closes the ball extraction opening is completely free when the balls are being extracted, so even if some impact is applied to the pachinko machine while balls are being extracted, the ball extraction opening will not be blocked. This has the effect that the balls can be completely removed without any problem of them falling out.
