BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to open a ball hole in the bottom wall of a lower bowl for storing pachinko balls and slide a shutter plate provided on the lower surface of the bottom wall of the lower bowl. ,
The present invention relates to a ball punching device for a lower ball dish in a pachinko machine in which a ball punching hole is opened, and in particular, a position where the shutter plate opens the ball punching hole using the pachinko balls stored in the lower ball dish. It can be stopped and held.

[0002]

2. Description of the Related Art Conventionally, in this type of lower ball dish removing device, stopper means for stopping a shutter plate is provided, and the shutter plate is stopped and held at a ball removing position where the ball hole is opened by the stopper means. This is known (see, for example, Japanese Utility Model Laid-Open No. 5-9583).

[0003]

In the conventional ball removing device for lower bowls, many moving parts are required, the structure is complicated, and the assembly is troublesome, and the cost is inevitably high. However, there is a problem that the stopper means cannot be released if the movable part is broken.

Further, even when there is no need to remove the ball because there is no pachinko ball in the lower bowl, sliding the shutter plate causes the stopper plate to stop and hold the shutter plate at the ball removing position. There was also the problem that the lower bowls of many pachinko machines were left in a ball-removed state due to mischief and harassment.

The present invention has been made in view of the above problems of the prior art. The object of the present invention is that the structure is simple and the conventional device can be obtained without making a great change. It is an object of the present invention to provide a ball punching device for a lower bowl dish in a pachinko machine that can stop and hold the shutter plate at the ball punching position and is not tampered with by the player.

[0006]

In order to achieve the above-mentioned object, the present invention provides a ball-draining hole in the bottom wall of a dish portion for storing pachinko balls and closes the ball-draining hole in the lower surface of the bottom wall. In the pachinko machine in which a shutter plate biased by a spring in the direction is provided, and the shutter plate is slid to a position where the ball hole is released, the pachinko ball in the plate part is balled out. The wall is provided with a slot communicating with the ball punching hole, and the shutter plate is provided with a first recessed portion in which a single pachinko ball falls into the shutter plate at a first position where the ball punching hole is fully opened. At the second position where the pachinko ball of the first concave portion is made to come into contact with the groove hole at the second position where the pachinko ball is in contact with the groove hole at the second position where it is in communication with the concave hole portion and substantially fully opens the ball hole. The second concave portion for stopping and holding the shutter plate and the second shutter plate By sliding into place et first position in which pachinko balls of the second recessed portion is provided and a recessed groove portion for feeding the ball vent hole.

[0007]

When the shutter plate is slid to the first position where the ball removing hole is fully opened, the first concave portion provided in the shutter plate matches the groove hole in the bottom wall and is stored in the lower ball dish. One of the pachinko balls falls. When the hand is released from the shutter plate in this state, the shutter plate is returned by the force of the spring in the direction of closing the ball-punching hole, and the pachinko ball in the first recess is depressed into the second recess. , The shutter plate is brought into contact with the groove hole and stopped at the second position where the ball hole is almost fully opened. Therefore, the pachinko ball on the plate can be removed even if the hand is released from the shutter plate.

When the shutter plate is slid again to the first position where the ball hole is fully opened after the ball is removed, the pachinko ball in the second concave portion is brought into contact with the groove hole, and the ball groove is removed from the groove. It is sent out and falls. As a result, the shutter plate automatically returns by the bias of the spring and closes the ball hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a pachinko machine equipped with the lower bowl of the present embodiment, FIG. 2 is a perspective view of the lower bowl, and FIG. 3 is an exploded perspective view thereof. In the figure, 1 is a pachinko machine body, 2 is its front frame, 3 is a game board located at the rear of the front frame 2, 4 is a glass frame that covers the upper part of the game board 3, and 5 is the lower part of the game board 3. An upper spherical plate 6 is attached to the front plate for covering, and a lower spherical plate 7 according to this embodiment is attached to the lower front face of the front frame 2.

As shown in FIGS. 2 and 3, the lower spherical dish 7 is divided into two parts, that is, a plate portion 8 and a cover member 9 to be attached to the plate portion 8. Then, a ball hole 11 is formed at a substantially central position of the bottom wall 10 of the dish 8, and a groove hole 12 is formed so as to communicate with the ball hole 11. Reference numeral 13 denotes a shutter plate that opens and closes the ball hole 11 of the bottom wall 10 of the dish portion 8. The shutter plate 13 has a lower surface of the bottom wall 10 of the dish portion 8 and a support frame 14 screwed to the lower surface of the bottom wall 10. It is slidably mounted between and, and is urged in the direction to close the ball-removing hole 11 by the elasticity of the spring 15 provided in the support frame 14. The groove hole 12 has a groove width that allows one pachinko ball to fall, and is provided in an inclined shape at a predetermined angle in the backward movement direction of the shutter plate 13. Further, a circular hole 22 having substantially the same size is formed in the support frame 14 at a position facing the ball removing hole 11.

On the front edge of the shutter plate 13, there is a plate 8
An operation portion 16 protruding outward is provided so as to project, and the shutter plate 13 can be slid by manually operating the operation portion 16. Further, a receiving piece portion 17 that closes the groove hole 12 is integrally provided on the rear side edge of the shutter plate 13.

In the receiving piece portion 17 of the shutter plate 13,
A first recess 18 in which one pachinko ball of the plate portion 8 is fitted into the dish portion 8 at the first position (see FIG. 5) where the shutter plate 13 is slid to fully open the ball removing hole 11 (see FIG. 5). A second communicating with the first concave portion 18 and opening the ball-removing hole 11 almost fully
At the position (see FIG. 6), the first recess 18 is aligned with the slot 12.
Second concave recessed portion 19 into which the pachinko ball of FIG. 2 is inserted, and a concave groove portion that slides the shutter plate 13 from the second position to the first position to send the pachinko ball of the second concave recessed portion 19 to the ball removing hole 11. 20 (see FIG. 7).

The first recessed portion 18 and the second recessed portion 19 are communicated with each other via a low blocking portion 21 as shown in FIG. As shown in FIG. 8 (b), the second recessed portion 19 has a slot 1 at least above the radius of the pachinko ball that has entered.
Its depth is chosen to abut 2. Further, the recessed groove portion 20 is opened at the side end of the receiving piece portion 17 and is formed in a shape intersecting with the groove hole 12, and the bottom surface thereof is formed in a gentle upward slope shape which is gentle toward the opening.

Next, the operation of this embodiment will be described with reference to FIGS. Normally, the shutter plate 13 is placed at a position that closes the ball hole 11 as shown in FIGS. 4 and 8A by the biasing force of the spring 15. The slot 12 is closed by the receiving piece 17 of the shutter plate 13. In this state, when a finger is put on the operation portion 16 and the shutter plate 13 is slid to the first position where the ball hole 11 is fully opened as shown in FIGS. 5 and 8B, the groove hole 12 and the first depression are formed. One of the pachinko balls stored in the dish portion 8 in conformity with the portion 18 naturally falls into the first recessed portion 18. It should be noted that when the shutter plate 13 is slid to the first position, one of the pachinko balls stored in the plate portion 8 will fall into the second recessed concave portion 19, but the pachinko ball is concave. It is sent out from the groove portion 20 to the ball removing hole 11 and is dropped there.

After sliding the shutter plate 13 to the first position, the hand is released from the operating portion 16 to release the shutter plate 1.
3 is moved back in the direction of closing the ball hole 11 by the urging force of the spring 15, whereby the pachinko ball B that has fallen into the first recess 18 is a damming portion as shown by the chain line in FIG. 8B. While riding over 21, it falls into the second concave portion 19 (see FIG. 6). Then, the pachinko ball B that has fallen into the second concave portion 19
As a result of the backward movement of the shutter plate 13, as shown in FIG. 8, a portion above the radius of the shutter plate 13 comes into contact with one side edge 12a of the slot 12. Therefore, even if the operator releases his / her hand from the operation portion 16, the shutter plate 13 opens the ball-removing hole 11 almost completely.
Since the pachinko ball of the plate portion 8 is stopped and held at the position, the ball can be dropped from the ball hole 11 into the circular hole 22.

On the other hand, to return the shutter plate 13 to its original position,
A finger is put on the operation portion 16 to slide the shutter plate 13 to the first position where the ball hole 11 is fully opened as shown in FIG. 7.
Along with this operation, first, the pachinko ball B that has fallen into the second recessed portion 19 moves together with the second recessed portion 19, and the pachinko ball B moves to the position shown in FIG.
As shown in (d), it abuts on the other side edge 12b of the groove hole 12, and then is guided to the concave groove portion 20 by the inclination of the side edge 12b of the groove hole 12 and is pushed forward and dropped into the ball removing hole 11. (See Fig. 7). Therefore, when the hand is released from the operating portion 16, the shutter plate 13 is moved back by the bias of the spring 15 to close the ball hole 11.

According to the present embodiment thus constructed,
When the shutter plate 13 is slid to the first position where the ball hole 11 is fully opened, one of the pachinko balls stored in the dish 8 is slid.
The individual pieces fall into the first recessed portion 18 formed in the shutter plate 13, and the pachinko balls that have fallen into the first recessed portion 18 are brought into contact with the groove holes 12 of the dish portion 8 so that the shutter plate 13 is opened. The ball hole 11 can be kept stopped at the second position where it is almost fully opened, and the shutter plate 13 can be released by a simple operation by sliding the shutter plate 13 to the first position again.

Moreover, even if all the pachinko balls stored in the plate portion 8 are removed, the pachinko ball B remains in the slot 12 of the plate portion 8 so that the player can see the pachinko ball B. It is possible for the player himself to perform a stop release operation of the shutter plate 13 in order to collect it. Therefore, it is less likely that the shutter plate 13 is left as it is until it is stopped at the ball removing position.

[0019]

As is apparent from the above description, the ball punching device for the lower bowl according to the present invention uses the pachinko balls stored in the lower bowl to stop and hold the shutter plate at the ball pulling position. Therefore, if there is no pachinko ball in the lower ball dish, the shutter plate cannot be stopped at the ball removing position.Therefore, in a situation where the shutter plate is left in the ball removing state due to mischief or harassment. Can be prevented.

Even if all the pachinko balls on the lower ball dish are removed, one pachinko ball remains on the dish so that the player can see the pachinko balls. Therefore, the player uses the shutter plate to collect the pachinko balls. The probability of performing the operation to return to the stop release position is extremely high, and therefore, it is less likely that the player will leave without leaving the shutter plate at the ball-removing position, which may cause trouble to the next player. This saves the employee the trouble of moving the shutter plate back.

Further, the ball removing device of the present invention can be constructed by the conventional number of parts and does not require extra movable parts, so that the structure is simple and is less likely to be damaged. Even if the shutter plate is broken and cannot hold the open state of the shutter plate, it has many advantages such that it can be used as usual for removing the ball.
