DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a pachinko machine, and FIG.
Is a perspective view of a lower ball receiving tray, and FIG. 3 is an exploded perspective view. A front frame 2 is provided on the front of the pachinko machine 1 so as to be openable and closable, and a game board 3 is located behind the front frame 2. Reference numeral 4 denotes a glass frame that covers an upper portion of the game board 3, and 5 denotes a front plate that covers a lower portion of the game board 3, and an upper ball receiving tray 6 is attached to the front surface thereof. On the lower front surface of the front frame 2, a lower ball tray 7 for storing excess balls in the upper ball tray 6 is mounted.

As shown in FIGS. 2 and 3, the lower ball receiving tray 7 includes a plate 8 and a cover member 9 attached to the upper portion of the plate 8.
And two parts. A ball hole 11 for dropping a large number of pachinko balls at the same time is formed substantially at the center of the bottom wall 10 of the dish portion 8 and a diameter of the pachinko ball is provided near the ball hole 11 separately from the hole 11. A drop-in hole 12 having a size substantially equal to that of the hole 12 is formed. Also the bottom wall 10
Is slanted downward toward the ball hole 11, so that all the pachinko balls stored in the dish 8 face the ball hole 11. 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. Due to the elasticity of a spring 15 as a biasing member provided in the interior 14, the biasing member 11 is constantly biased in a direction to close the ball hole 11.

At 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. On the rear side edge of the shutter plate 13, a receiving piece 17 for closing the drop-in hole 12 at a position where the ball hole 11 is closed (see FIG. 4) is provided integrally, and an engaging portion 18 is provided. As shown in FIG. 6, the engaging surface of the engaging portion 18 is inclined toward the lower left in the figure, and the other surface is inclined toward the lower right in the figure.

As shown in FIG. 3, the support frame 14 is provided with a through hole 19 having a size substantially the same as that of the ball hole 11 at a position opposite to the hole 11 as shown in FIG.
A swing member 20 is pivotally supported by a shaft pin 22 on the shafts 21 and 21.

As shown in FIG. 6A, the swing member 20 is always rotated downward (counterclockwise) by the weight 23.
And the one end thereof has
A ball support portion 24 that faces the lower portion of the ball 2 and supports the pachinko ball that has fallen into the fall-in hole 12 is bent. The center of the pachinko ball that has fallen into the fall-in hole 12 is located above the receiving piece 17 of the shutter plate 13 as shown in FIG. The lower part of the fallen pachinko ball is pushed back into the dish portion 8. On the other hand, a locking portion 25 that engages with the engaging portion 18 is formed at the opposite end where the ball support portion 24 is formed. The locking surface of the locking portion 25 is an inclined surface that is inclined downward in the ball-pulling direction so that engagement with the engaging portion 18 can be easily released. The weight of the weight 23 is selected so that the swinging member 20 swings when a ball weight greater than one pachinko ball is applied to the ball support portion 24.

Next, the operation of removing the ball from the ball tray will be described with reference to the drawings. Normally, the shutter plate 13 closes the ball hole 11 as shown in FIG. 4 by the bias of the spring 15, and at this time, the falling hole 12 becomes the receiving piece 17 of the shutter plate 13 as shown in FIG. Is blocked by In this state, when a large amount of pachinko balls are stored in the dish portion 8, as shown in FIG. 6B, a finger is put on the operation portion 16 to release the shutter plate 13 to open the ball hole 11. When the ball is slid, the receiving piece 17 is simultaneously moved to open the drop-in hole 12, and one of the pachinko balls stored in the dish 8 naturally falls into the drop-in hole 12 to support the ball. It is supported by the part 24. As the ball weight of another pachinko ball is applied to the pachinko ball supported by the ball support portion 24, FIG.
As shown in (c), the swinging member 20 rotates (clockwise) against the bias of the weight 23, and the locking portion 25 moves upward. When the shutter plate 13 is further slid to the side where the ball hole 11 is opened, the locking portion 25 of the swinging member 20 is temporarily lowered by the inclined surface of the engaging portion 18 against the ball weight applied to the ball support portion 24. Move.

As soon as the shutter plate 13 is moved to a position where the ball hole 11 is almost fully opened, the engaging portion 18 passes through the locking portion 25 and the swinging member 20 moves up to the original position due to the ball weight. . In this state, when the hand is released from the operation unit 16, the shutter plate 13 attempts to return in the direction to close the ball hole 11 by the bias of the spring 15, but as shown in FIG. The engaging portion 25 on the side moved upward engages with the engaging portion 18 to prevent the returning movement. Therefore, even if the hand is released from the operation unit 16, the weight of the ball applied to the ball support unit 24 exceeds the urging force of the spring 15, and the shutter plate 13 fully opens the ball hole 11 as shown in FIG. Will be locked and held. Then, the pachinko balls of the dish portion 8 fall out of the ball holes 11 through the through holes 19 and are extracted.

When the pachinko balls of the plate portion 8 are thus extracted and the weight of the balls on the ball support portion 24 decreases,
As shown in FIG. 6E, the swing member 20 rotates upward (counterclockwise) because the weight 23 wins over the ball weight on the ball support portion 24. Accordingly, the engaging portion 18 and the locking portion 25
Is released, and the shutter plate 13 automatically returns to the position where the ball hole 11 is closed by the bias of the spring 15. At this time, the pachinko ball that has fallen into the fall-in hole 12 is pushed below the pachinko ball by the receiving piece 17 of the shutter plate 13 as shown in FIG. And the ball removal ends as shown in FIG. 6 (f).

Further, the shutter plate 13 closes the ball hole 11 before the pachinko ball dropped into the drop hole 12 is returned into the dish portion 8, and the pachinko ball remains in the dish portion 8. In this case, if the shutter plate 13 is moved in the opening direction again,
Since the ball weight that exceeds the weight 23 is not applied to the ball support portion 24, the shutter plate 13 can reliably remove the remaining pachinko ball without being locked. Although the drop-in hole 12 is provided separately from the ball hole 11, it may be provided in communication with the ball hole 11. FIG. 7 (a),
8B, the shutter plate 13 is rotated about a support shaft 36 to open and close the hole 11, and the shutter is opened as shown in FIGS. 8A and 8B. Even in the case of a ball punching structure in which the ball punching hole 11 is opened and closed by sliding the plate 13 in the front-back direction, the same can be achieved by changing the shape of the shutter plate 13 and the positional relationship between the ball punching hole 11 and the drop-in hole 12. So applicable.

FIG. 9 is a view in which a disc-shaped closing plate 26 for closing the drop-in hole 12 is provided integrally with the ball supporting portion 24 of the swinging member 20. When the closing plate 26 is provided on the swinging member 20 in this manner, as shown in FIGS.
The weight of the pachinko balls stored in the swinging member 20 is applied to the closing plate 26, and the swinging member 20 rotates (clockwise), and the locking portion 25 on the side on which the swinging member 20 moves upward engages with the engaging portion 18. Then, the shutter plate 13 is locked and held at a position where the ball hole 11 is opened. When the pachinko ball is withdrawn from the ball hole 11, the ball weight on the closing plate 26 decreases and the swing member 20
Is rotated by the weight 23 (counterclockwise) to release the locked state of the shutter plate 13, and the closing plate 26 closes the drop-in hole 12, and the pachinko ball dropped into the drop-in hole 12 at the same time. Is returned to the dish portion 8 and dropped from the ball removing hole 11.
For this reason, since the swinging member 20 swings at the same time when the shutter plate 13 is released from the open state, the pachinko balls dropped into the drop-in holes 12 are returned to the dish portion 8, so that the pachinko balls remain in the dish portion 8. The ball can be removed without fail. When the closing plate 26 is provided on the swing member 20, the receiving piece 17 of the shutter plate 13 becomes unnecessary.

FIG. 11 shows a configuration in which the engaging portion 18 of the shutter plate 13 is formed in a projecting shape so as to also serve as a swing regulating portion 27 for regulating the downward rotation of the swing member 20. The engaging portion 18 on the side surface of the swing regulating portion 27 is
The engaging portion 18 and the rocking member 20
Is easily engaged with the locking portion 25. in this way,
FIG. 1 shows a case where the swing regulating portion 27 is provided on the shutter plate 13.
As shown in FIGS. 2 (a) to 2 (d), the swing restricting portion 27 is in contact with the upper surface of the swing member 20 until the shutter plate 13 moves to a position where the ball hole 11 is opened. Therefore, even when the ball removal hole 11 is closed by the shutter plate 13, even if the closing plate 26 receives a ball weight exceeding the weight 23, the swing member 20 does not rotate downward, and the shutter Since the swing member 20 does not rotate downward until the plate 13 moves to the position where the ball hole 11 is opened, it is possible to swing the swing member 20 unnecessarily against the ball weight. Thus, the ball removing operation can be performed extremely smoothly. It should be noted that the swing regulating portion 27 is
Although it has been described that they are also used, they may be provided separately from the engaging portions 18.

According to the first embodiment described above,
When the shutter plate 13 is slid to a position at which the ball hole 11 is opened, one of the pachinko balls stored in the dish portion naturally falls into the fall-in hole 12, and the ball weight of the pachinko ball causes the ball to fall. The rocking member 20 provided separately from the shutter plate 13 is rotated, and the locking portion 25 on the side rotated upward is locked to the engaging portion 18, and the shutter plate 13 opens the ball hole 11. The swinging member 20 is rotated to release the locking of the shutter plate 13 to remove the pachinko ball from the pachinko ball and reduce the weight of the ball on the swinging member 20 to release the ball. 11 can be automatically returned to the closing position.

Next, a ball punching device for a ball tray according to a second embodiment will be described with reference to FIGS. The difference between the ball punching device of the second embodiment and the ball punching device of the first embodiment is mainly that of the shutter plate structure. Is shown. To explain this,
The shutter plate 28 that opens and closes the ball hole 11 formed in the bottom wall 10 of the dish portion 8 has a notch opening 29 at a substantially central position. It is constructed so as to pivot freely. As shown in FIG. 14, the shutter plate 28
The hole 1 is urged by the
1 is closed, and at this time, the drop-in hole 12 is closed at the left side of the cutout opening 29.

On the other hand, a plate portion 8 is provided at the front of the swinging member 30.
An operation part 32 protruding outward is provided integrally,
By manually operating the operation unit 32, the swing member 30
Can slide integrally with the shutter plate 28. Then, as shown in FIG. 15, when the shutter plate 28 is slid to the position where
The pachinko ball which falls into the drop hole 12 and can be supported below. In addition, as shown in FIG.
When the ball is closed, it is rotated upward (counterclockwise) and is supported by the lower surface of the bottom wall 10 of the dish portion 8. If a ball weight heavier than one pachinko ball is applied, as shown in FIG. The center of gravity is provided so as to rotate downward (clockwise).
A concave groove 34 as an engaging portion is provided on a front wall 33 of the plate portion 8 on which the shutter plate 28 is swingably supported, and a shutter plate is provided on an upper surface of the operation portion 32 of the swing member 30. The protrusion 35 as an engaged portion engages with the concave groove 34 when the ball 28 is slid to the position where the ball hole 11 is opened.
Is protruding.

In the ball punching device of the second embodiment configured as described above, both the ball punching hole 11 and the drop-in hole 12 are closed by the shutter plate 28 as shown in FIGS. 14 and 16A. 15, a finger is put on the operation unit 32 to remove the pachinko balls stored in the plate portion 8, and the shutter plate 28 is integrated with the swinging member 30 to open the ball removing hole 11 shown in FIG. 15. When it is slid, the swinging member 30 moves below the drop-in hole 12. For this reason, when the finger is released from the operation unit 32 in this ball-off state, the shutter plate 2
When the swinging member 30 is moved back in the direction to close the ball removing hole 11 by the bias of the spring 15, the swing member 30 is moved by the ball weight of the pachinko ball falling into the falling hole 12 as shown in FIG. With the shaft 31 as a fulcrum, it rotates (clockwise direction), and the projection 35 of the operation unit 32 on the side moved upward engages with the concave groove 34 of the dish 8. Accordingly, the shutter plate 28 is securely locked and held at a position where the ball punching hole 11 shown in FIG. 15 is opened, and removes the ball of the pachinko ball of the plate portion 8 with the hand released from the operation portion 32. be able to.

On the other hand, when the pachinko ball of the plate portion 8 is extracted and the weight of the ball on the rocking member 30 decreases, the rocking member 3
In FIG. 16 (a), 0 is rotated upward by its own weight with the shaft 31 as a fulcrum.
The rotation returns to the position shown in FIG. As a result, the operation portion 32 of the swinging member 30 moves down, and the engagement between the concave groove 34 of the plate portion 8 and the projection 35 of the operation portion 32 is released. Automatically returns to the position where the hole 11 is closed, and the falling hole 12 is also closed at the same time.

In the case of the second embodiment, for example, when the shutter plate 28 is slid to a half-open state where a ball can be removed,
The pachinko balls stored in the dish portion 8 are set by setting the mutual positional relationship between the ball removing hole 11, the falling hole 12, and the swinging member 30 so that the swinging member 30 is not positioned below the falling hole 12. The game can be played while removing the ball little by little irrespective of the swing member 30, which is convenient for the player.

In the second embodiment, the shutter plate 28 is described as being slidable in the left and right directions. However, as shown in FIGS. 17A and 17B, the shutter plate 28 is supported. FIG. 18 shows a structure in which the ball hole 11 is opened and closed by turning the shaft 38 around the center.
As shown in (a) and (b), even in the case of a ball punching structure in which the ball punching hole 11 is opened and closed by sliding the shutter plate 28 in the front-back direction, the shape of the shutter plate 28, the swing member 30, and the ball punching The same can be applied by changing the mutual positional relationship between the hole 11 and the drop-in hole 12.

In the above-described second embodiment, the shutter plate 28 is engaged with the projection 34 of the operating portion 32 of the swinging member 30 by engaging the concave groove 34 of the dish portion 8 with the ball hole 1.
1 has been described as being locked at the open position. However, as shown in FIGS. 19A and 19B, the operation is performed by making the concave groove 34 substantially equal to the lateral width of the operating portion 32 of the swinging member 30. The portion 32 and the groove 34 may be directly engaged. Further, as shown in FIGS. 20 (a) and 20 (b), an engaging projection 37 as an engaging portion is provided on the upper surface of the support frame 14 which is screwed to the lower surface of the plate portion 8, and is shown in FIG. As described above, the downwardly rotated side surface of the swing member 30 may be engaged with the engagement protrusion 37 as the engaged portion at the position where the shutter plate 28 opens the ball hole 11.

Thus, in the case of the second embodiment,
When the pachinko ball stored in the plate portion 8 is swung by the ball weight, the shutter plate 28 is locked and held at a position where the ball punching hole 11 is opened. The swinging member 30, which functions to automatically return the shutter to the closing position, is pivotally supported by the shutter plate 28 to form an integral structure with the shutter plate 28, so that the swinging member 30 swings with the shutter plate 13 as in the first embodiment. It is not necessary to separately assemble the moving member 20, so that the ball removing structure can be simplified, and the workability can be improved and the cost can be reduced.
