Field of the Invention The present invention relates to a ball hole formed in a bottom wall of a lower ball tray for storing pachinko balls, and a hole is formed in a lower surface of the bottom wall of the lower ball plate. By sliding the provided shutter plate,
The present invention relates to a ball punching device for a lower ball tray in a pachinko machine in which a ball punching hole is opened to punch a ball, and in particular, a position where a shutter plate is opened using a pachinko ball stored in the lower ball tray. It is designed to be able to stop and hold. 2. Description of the Related Art Conventionally, in a ball punching device for a lower ball dish of this type, stopper means for stopping a shutter plate is provided, and the shutter plate is set at a ball punching position at which a ball hole is opened by the stopper means. A system in which the stop is maintained is known (for example, see Japanese Utility Model Laid-Open No. 5-9583). [0003] The conventional ball punching device for a lower ball tray requires a large number of movable parts, has a complicated structure, and requires much time for assembling. In addition, when the movable part is broken, the stopper means cannot be released. Further, even if there is no pachinko ball in the lower ball plate and there is no need to remove the ball, if the shutter plate is slid, the shutter plate is stopped and held at the ball removing position by the stopper means. There was also a problem that the lower ball plates of many pachinko machines were left unballed due to mischief or harassment. [0005] The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a simple structure and a reliable device without greatly changing the conventional device. It is an object of the present invention to provide a ball punching device for a lower ball tray in a pachinko machine which can stop and hold a shutter plate at a ball pulling position and does not play with a player. In order to achieve the above object, according to the present invention, there is provided a ball hole formed in a bottom wall of a lower ball dish, and a spring is urged by a spring in a direction to close the hole. In a ball punching device for a lower ball dish comprising a shutter plate and a support frame for slidably supporting the shutter plate, a through hole through which a single pachinko ball can be dropped is formed near the ball hole in the bottom wall. The shutter plate is provided with a first hole for fully opening a ball hole.
The pachinko ball matches the through hole in the bottom wall at the position and has a holding portion into which the pachinko ball falls and the pachinko ball matches the through hole in the bottom wall at the second position where the ball hole is almost fully opened. A penetrating hole is provided for dropping, and a pachinko ball dropped into the holding portion of the bent slot at the first position of the shutter plate abuts on the support frame to stop the shutter plate at the second position. A joint portion, a first drop hole corresponding to the open end of the bent slot at a first position of the shutter plate, and a second drop hole matching the through hole are provided. When the shutter plate is slid to the first position where the ball hole is fully opened, the holding portion of the bent slot matches the through hole in the bottom wall, and the pachinko ball stored in the lower ball plate One falls naturally into the holding part. When the hand is released from the shutter plate in this state, the shutter plate moves back in the direction to close the ball hole by the bias of the spring, but the pachinko ball dropped into the holding hole comes into contact with the engaging step of the support frame. As a result, the shutter plate is stopped at the second position where the ball hole is almost fully opened. Therefore, the pachinko ball in the dish portion can be removed even if the hand is released from the shutter plate. Further, when the shutter plate is stopped at the second position, the through hole and the through hole are aligned, and one of the pachinko balls stored in the lower ball dish falls naturally into the through hole. .
This pachinko ball is a dummy ball indicating that the ball hole is almost fully opened. When the shutter plate is again slid to the first position for fully opening the hole for removing the ball after the ball has been removed, the pachinko machine stops the shutter plate at the second position by contacting the engaging step of the support frame. The sphere is guided by the bent slot and falls from the first drop hole. As a result, the shutter plate is automatically moved back by the bias of the spring to close the hole. Further, the pachinko ball serving as the dummy ball that has fallen into the through hole falls downward from the second drop hole. 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 a lower ball dish of the present embodiment, FIG. 2 is a perspective view of the lower ball dish, 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 plate 6 is attached to the front surface of the cover, and a lower plate 7 according to the present embodiment is attached to the lower front surface of the front frame 2. As shown in FIGS. 2 and 3, the lower ball tray 7 is divided into a tray portion 8 and a cover member 9 attached to the tray portion 8. Then, a ball hole 11 is opened substantially at the center of the bottom wall 10 of the dish portion 8, and a through hole 12 is provided near the ball hole 11, where a single pachinko ball can be dropped. 13 is a ball hole 11 in the bottom wall 10 of the dish 8
The shutter plate 13 is slidably mounted between the 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. 14 by the elasticity of a spring 15 provided inside
1 is biased in the closing direction. A plate 8 is provided on the front edge of the shutter plate 13.
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, a receiving piece 17 for closing the through hole 12 is provided integrally with the rear side edge of the shutter plate 13 at a position where the ball hole 11 is closed. The receiving piece 17 of the shutter plate 13 has a holding portion 18 that matches the through hole 12 at a first position (see FIG. 5B) where the shutter plate 13 is slid to fully open the hole 11. A bent slot 19 and a through hole 20 that matches the through hole 12 at a second position (see FIG. 5C) where the ball hole 11 is almost fully opened are provided. On the other hand, a circular hole 21 of substantially the same size is formed in the support frame 14 at a position opposite to the ball hole 11. In addition, a long groove-shaped concave portion 22 is formed at a position facing the receiving piece 17, and the shutter plate 1 is provided in the concave portion 22.
3, the first position corresponding to the open end of the bent slot 19 at the first position.
A drop hole 23 and a second drop hole 24 corresponding to the through hole 20 are respectively opened. Further, the recess 22 has a shallow recessed portion 25 for receiving the pachinko ball dropped into the holding portion 18 or the through hole 20 and the pachinko ball dropped into the holding portion 18 to stop the shutter plate 13 at the second position. And an engaging step 26 that functions to cause the engagement. The recess 22
Is formed as a gentle slope toward the first drop hole 23. Next, the operation of this embodiment will be described with reference to FIGS. Normally, as shown in FIG.
Is closed. The through hole 12 is closed by a receiving piece 17 of the shutter plate 13 as shown in FIG. In this state, a finger is put on the operation unit 16 to release the shutter plate 1.
As shown in FIGS. 5B and 6B, when the ball 3 is slid to the first position where the ball hole 11 is fully opened, the through-hole 12 and the holding portion 18 of the bent groove 19 are aligned with each other. One of the pachinko balls stored in the part 8 naturally falls into the holding part 18. When the shutter plate 13 is slid to the first position, the pachinko balls stored in the dish 8 are inserted into the through holes 20.
However, the pachinko ball is carried to the second drop hole 24 and is then dropped downward. 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 removing hole 11 by the bias of the spring 15, but the pachinko ball B dropped into the holding portion 18 moves through the concave portion 22 and comes into contact with the engaging step portion 26. The return is prevented (FIG. 5 (c) and FIG. 6).
(C)). Therefore, even if the hand is released from the operation unit 16, the shutter plate 13 is stopped and held at the second position where the ball punching hole 11 is almost fully opened, and the pachinko ball of the dish 8 is moved from the ball punching hole 11 to the circular hole 21. To drop the ball. At the same time as the shutter plate 13 is stopped and held at the second position, the pachinko balls stored in the dish portion 8 fall into the through holes 20 as dummy balls B1. On the other hand, 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 moved as shown in FIG.
Then, as shown in FIG. 6D, the ball removing hole 11 is slid to the first position where it is fully opened. Then, the open end of the bending slot 19 and the first drop hole 23 coincide with each other, and the pachinko ball B, which abuts on the engaging step 26 and stops and holds the shutter plate 13 at the second position, is bent. The pachinko ball B1 which is guided by the inclined bottom surface of the concave portion 22 and falls into the first drop hole 23, and at the same time, the through hole 20 and the second drop hole 24 coincide with each other and fall into the through hole 20 as a dummy sphere, It falls into the second drop hole 24.
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. Although the embodiment has been described above, according to this embodiment, when the shutter plate 13 is slid to the first position in which the ball hole 11 is fully opened, the pachinko balls stored in the dish portion 8 are removed. One of the pachinko balls B falls into the holding portion 18 formed on the shutter plate 13 and falls into the holding portion 18.
As a result, the shutter plate 13 can be kept stopped at the second position where the ball hole 11 is almost fully opened, and the stop of the shutter plate 13 can be released only by sliding the shutter plate 13 again to the first position. It can be done with simple operation. Moreover, even if all the pachinko balls stored in the dish portion 8 are removed, the pachinko balls B1 as dummy balls are left in the dish portion 8 so as to be seen by a player.
The player himself / herself can perform a stop release operation of the shutter plate 13 in order to collect the pachinko ball B1. Therefore, it is less likely that the shutter plate 13 is left unattended at the ball-pulling position. In the above embodiment, the ball hole 1
Although the configuration has been described in which the through hole 12 and the through hole 12 are provided separately, for example, as shown in FIG. 7, the through hole 12 and the ball hole 11 may be provided in a communicating manner. With this configuration, the pachinko balls stacked on the pachinko balls B1 serving as dummy spheres accommodated in the through holes 20 at the second position of the shutter plate 13 hold when the shutter plate 13 returns to the first position. The shutter plate 13
Can be prevented from being opened again. Further, as shown in FIG. 8, the through hole 12 and the ball hole 11 may be formed in communication with each other, and a bank 29 may be formed along the periphery of the through hole 12. With this configuration, it is possible to further prevent the shutter plate 13 from being unnecessarily opened. As is apparent from the above description, the ball punching device for the lower ball tray of the present invention uses the pachinko balls stored in the lower ball tray to move the shutter plate to the ball pulling position. Since the pachinko ball is not present in the lower bowl, the shutter plate cannot be stopped at the ball-pulling position because the pachinko ball is not held in the lower ball tray, so that the ball is left in a ball-pulling state due to mischief or harassment. Can be prevented. Further, even if all the pachinko balls on the lower ball plate are removed, the pachinko balls are left as dummy balls on the plate portion so as to be seen by the player. The probability of performing the operation of returning the shutter plate to the stop release position in order to collect the game is extremely high, and therefore, the player is less likely to leave the shutter plate in the ball-pulling position while leaving the shutter plate. This eliminates the need to bother the player or to move the shutter plate back by the employee. Further, the ball punching device of the present invention can be constituted by the conventional number of parts, and since no extra movable parts are required, the structure is simple and there is little breakage. Even if the shutter plate is broken and the open state of the shutter plate cannot be maintained, there are many advantages such that the ball can be used in a conventional manner.
