BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball punching device for a ball tray in a pachinko machine capable of performing the above-mentioned operations.

[0002]

2. Description of the Related Art Conventionally, a ball hole is formed in a bottom wall of a dish portion for storing pachinko balls, and a shutter plate for opening and closing the ball hole is provided slidably on the lower surface of the bottom wall. The ball punching device of the ball tray in the pachinko machine which always urges the ball punching hole to the closed position and closes the ball punching hole by the stopper means so that the shutter plate can be locked and held. This is known (for example, see Japanese Utility Model Laid-Open No. 5-9583).

[0003]

In the conventional ball punching device for a ball tray, a large number of movable parts are required, the structure is complicated, and the assembling is troublesome, so that the cost is increased. When the movable part is broken, there is a problem that the stopper means cannot be released.

Further, even if there is no pachinko ball on the plate portion and there is no need to remove the ball, if the shutter plate is slid, the shutter plate will be stopped and held at the ball removal position by the stopper means, so that there is a mischief. There was also a problem that the ball saucers of many pachinko machines were left unballed due to harassment.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to reliably remove a shutter plate with a simple structure without greatly changing a conventional ball removing device. A ball punching device for a ball tray in a pachinko machine that can be stopped and held at a position, can easily perform a ball pulling operation, and is not left in a ball pulling state due to mischief or harassment by a player. It is assumed that.

[0006]

In order to achieve the above object, according to the present invention, a ball hole is opened in a bottom wall of a dish portion for storing pachinko balls, and a ball hole is closed on a lower surface of the bottom wall. A 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 punching hole is released so as to pull out the ball from the pachinko ball in the plate portion. A first groove is provided in the wall, and the first groove fully opens the hole for removing the ball against the bias of the spring.
When the shutter plate is slid to the position, the pachinko balls in the dish part can fall in, and the shutter plate almost fully opens the ball hole through the bias of the spring by releasing the hand from the shutter plate When returning to the second position,
The shutter plate is stopped and held by a pachinko ball that has fallen into the slot.

[0007] The ball receiving device of the ball receiving tray configured as described above slides to the first position in which the ball removing hole is fully opened without manually adjusting the shutter plate when removing the pachinko ball in the bowl portion. Even if the hand is released, the shutter plate can be reliably stopped and held at the second position where the ball hole is almost fully opened by the pachinko ball falling into the slot. For this reason, it is not necessary to slide to the position to open the ball-extraction hole while being conscious of the shutter plate, and the ball-extraction operation becomes easy.
Further, it becomes possible for the player to easily recognize that the ball is removed by the pachinko ball falling into the slot and the ball removing hole is opened.

[0008]

Next, embodiments of the present invention will be described with reference to the drawings. 1 is a front view of a pachinko machine, FIG. 2 is a perspective view of a lower ball tray, and FIG. 3 is an exploded perspective view thereof. In the figure, 1 is a pachinko machine main body, 2 is a front frame thereof, 3 is a game board located at the rear of the front frame 2, 4 is a glass frame covering an upper portion of the game board 3, and 5 is a lower portion of the game board 3. An upper ball pan 6 is attached to the front face plate to be covered, and a lower ball pan 7 is mounted below the upper ball pan 6 and in front of the front frame 2.

As shown in FIGS. 2 and 3, the lower ball receiving tray 7 is divided into a dish portion 8 and a cover member 9 attached to the dish portion 8, and is formed in two parts. Then, the bottom wall 1 of the dish 8
A ball hole 11 is opened at a substantially central position of 0, and a slot 12 is opened in communication with the ball hole 11. Reference numeral 13 denotes a shutter plate which opens and closes the ball hole 11 in the bottom wall 10 of the plate portion 8. The shutter plate 13 includes a lower surface of the bottom wall 10 of the plate portion 8 and a support frame 14 screwed to the lower surface of the bottom wall 10. And is slidably mounted between them, and is constantly urged in a direction to close the ball hole 11 by the elasticity of a spring 15 provided in the support frame 14. In addition, the slot 12 is selected to have a slot width in which one pachinko ball can be dropped, and the shutter plate 1
3 is inclined at a predetermined angle in the backward direction.
Further, a circular hole 22 having substantially the same size is formed in the support frame 14 at a position facing the ball hole 11.

On the front edge of the shutter plate 13, a plate portion 8 is provided.
An operation unit 16 is provided so as to protrude outward from the shutter plate 13, and the shutter plate 13 can be slid by manually operating the operation unit 16. Further, on the rear side edge of the shutter plate 13, a receiving piece 17 for closing the slot 12 when the ball hole 11 is closed is provided integrally.

On the other hand, the receiving piece 17 of the shutter plate 13
The first concave portion 18 into which one pachinko ball of the dish portion 8 falls into alignment with the slot 12 at a first position (see FIG. 5) where the ball hole 11 is fully opened, A second concave portion that communicates with the concave portion 18 and matches the slot 12 to drop the pachinko ball of the first concave concave portion 18 at a second position (see FIG. 6) where the ball hole 11 is almost fully opened. 19, and a groove 20 (see FIG. 7) for sliding the shutter plate 13 from the second position to the first position to feed the pachinko balls of the second concave portion 19 to the ball hole 11.

As shown in FIG. 8, the first concave portion 18 and the second concave portion 19 are communicated via a low dam portion 21. As shown in FIG. 8B, the second concave portion 19 has at least a portion above the radius of the fallen pachinko ball as the slot 1.
2, the depth of which is selected. Further, the concave groove portion 20 is opened at a side end of the receiving piece portion 17 and is formed so as to intersect with the groove hole 12, and the bottom surface thereof is formed to have a gentle upward slope toward the opening.

Next, the operation of the present embodiment will be described with reference to FIGS. Normally, the shutter plate 13 is placed at a position to close the ball hole 11 as shown in FIGS. The slot 12 is closed by the receiving piece 17 of the shutter plate 13. In this state, a finger is put on the operation unit 16 and the shutter plate 13 is slid to the first position where the ball hole 11 is fully opened as shown in FIG. 5 and FIG. One of the pachinko balls stored in the dish portion 8 coincides with the portion 18 and naturally falls into the first concave portion 18. When the shutter plate 13 is slid to the first position, one of the pachinko balls stored in the dish portion 8 falls into the second recessed portion 19, but the pachinko ball is recessed. It is sent out from the groove portion 20 to the ball hole 11 and dropped as it is.

After the shutter plate 13 is slid to the first position and then released from the operation unit 16, the shutter plate 1 is released.
3 moves back in the direction to close the ball hole 11 by the bias of the spring 15, whereby the pachinko ball B falling into the first concave portion 18 becomes a damming portion as shown by a chain line in FIG. 21 and fall into the second concave portion 19 (see FIG. 6). And the pachinko ball B dropped into the second concave portion 19
8, the upper portion of the radius of the shutter plate 13 is brought into contact with one side edge 12a of the slot 12 as shown in FIG. Therefore, even if the hand is released from the operation unit 16, the shutter plate 13 opens the ball hole 11 almost completely.
As a result, the pachinko ball in the dish portion 8 can be dropped from the ball hole 11 into the circular hole 22 to remove the ball.

As described above, according to the present embodiment, the pachinko ball B of the dish portion 8 is formed on the shutter plate 13 by sliding the shutter plate 13 to the first position where the ball hole 11 is fully opened. The pachinko ball B, which has fallen into the first concave portion 18 and has been released from the shutter plate 13 in this state, has fallen into the first concave portion 18 immediately with the return movement of the shutter plate. The shutter plate 13 is stopped at the second position where the pachinko ball B dropped into the portion 19 and further dropped into the second concave portion 19 comes into contact with the slot 12 of the dish portion 8 and almost fully opens the ball hole 11. Therefore, for example, even if the hand is released in a state where the shutter hole 13 is slid to the first position in which the ball hole 11 is fully opened without manually adjusting the shutter plate 13, the slot 1
Since the shutter plate 13 can be reliably stopped and held at the second position where the ball punching hole 11 is almost fully opened by the pachinko ball falling into the position 2, the ball punching hole 11 is opened while being aware of the shutter plate 13. There is no need to slide the ball, and the ball removing operation can be easily performed.

To return the shutter plate 13 to its original position,
A finger is put on the operation unit 16 and the shutter plate 13 is slid to the first position where the ball hole 11 is fully opened as shown in FIG.
As a result, the pachinko ball B falling into the second concave portion 19 moves together with the second concave portion 19, and moves to the other side edge 12b of the slot 12 as shown in FIG. Then, it is guided to the groove 20 by the inclination of the side edge 12b of the slot 12 and is pushed forward and falls into the ball hole 11 (see FIG. 7). Accordingly, when the hand is released from the operation unit 16, the shutter plate 13 is moved back by the bias of the spring 15 to close the ball hole 11.

[0017]

As is apparent from the above description, the ball removing device for a ball tray according to the present invention has a groove formed in the bottom wall of the plate portion, and the groove is formed against the bias of the spring. When the shutter plate is slid to the first position at which the ball hole is fully opened, the pachinko ball in the dish portion can drop in. The shutter plate is released by releasing the shutter plate and biasing the spring. When the ball is returned to the second position where the ball hole is almost fully opened, the shutter plate is stopped and held by the pachinko ball dropped into the slot, so that the ball is removed from the pachinko ball in the dish portion. The second position where the ball hole is almost fully opened by the pachinko ball falling into the slot even if the hand is released while sliding to the first position where the ball hole is fully opened without manually adjusting the shutter plate. Shutter plate It is possible to stop holding,
There is no need to slide the ball-extraction hole to the position where the ball-extraction hole is opened while being conscious of the shutter plate, and the ball-extraction operation can be easily performed.

Further, if there is no pachinko ball on the plate portion, the shutter plate cannot be stopped at the ball-pulling position, and therefore, it is possible to prevent a situation in which the shutter plate is left in a ball-pulling state due to mischief or harassment. Even if all the pachinko balls on the plate are removed, one pachinko ball remains on the plate so that the player can see it, and the player returns the shutter plate to the stop release position to collect the pachinko balls. The probability of performing the operation is extremely high, and therefore, the player is less likely to leave the shutter plate at the ball-pulling position and leaves, so that the next player is annoying or the employee removes the shutter plate. The trouble of moving back can be saved.

Further, the ball punching device of the present invention can be constituted by the conventional number of parts and does not require extra movable parts, so that the structure is simple and the damage is less likely to occur.
Even if the shutter plate is broken and the open state of the shutter plate cannot be maintained, there are many advantages such that normal ball pulling operation is not affected at all.
