And a middle member 5 installed between the mounting base 3. The mounting base 3 is provided with a prize ball supply port 7 that communicates with a prize ball discharge gutter 6 of a mechanism plate of a pachinko machine. Further, on the mounting base 3, a convex lens-shaped transparent bar 8 is provided at an upper position,
A through hole 9 for allowing a handle (not shown) for adjusting a hitting ball to pass through is provided at a lateral position, and a micro switch 10 and the like for operating a single shot of a hitting ball are provided above the through hole 9.

The middle member 5 has a ball receiving tray 11 that surrounds the prize ball supply port 7 of the mounting base 3 and a shaft retainer 13 for an ashtray 12 which will be described later. The ball receiving tray 11 is provided with a ball punching device A including a circular ball punching hole 14 formed in the bottom wall 11a and a slidable shutter plate 15 for opening and closing the ball punching hole 14. The shutter plate 15 is the bottom wall 1 of the ball saucer 11.
It is slidably mounted between the outer surface of 1a and a guide cover 16 fixed to the outer surface of the bottom wall 11a by a screw, and is urged in the direction to close the ball hole 14 by the elasticity of a spring 17 installed in the guide cover 16. It Also, the shutter plate 1
5 has an operation piece 18A protruding from one side edge, and by projecting the operation piece 18A from the guide cover 16, the shutter plate 15 can be manually operated by the player. The guide cover 16 includes an operation piece 18
A low convex rail 19 is formed which contacts A and guides the sliding direction of the shutter plate 15.

The ball removing device A is provided with stopper means. The stopper means in the first embodiment includes a substantially L-shaped through groove 20 provided in the guide cover 16 in plan view.
And a pin 21 that fits loosely into the through-groove 20 that is vertically provided on the shutter plate 15. The through groove 20 includes a straight portion 20a parallel to the convex rail 19, an arc portion 20b bent from the end of the straight portion 20a, and a stop portion 20c bent from the end of the arc portion 20b to the ball hole 14 side. .

Next, the ball removing operation will be described. Normally, the shutter plate 15 is biased by a spring 17 as shown in FIGS.
In the forward position shown in FIG. 6, the hole 14 is closed.
Therefore, first, a ball box is placed under the ball hole 14 and then the shutter plate 15 is slid by putting a finger on the operation piece 18A.
The shutter plate 15 slides straight by being guided by the linear portion 20a of the through groove 20 and the convex rail 19 at first. Next, when the pin 21 reaches the end of the straight portion 20a of the through groove 20, the front side of the operation piece 18A (the side of the ball hole 14) is pulled toward you, and the pin 21 enters the arc portion 20b of the through groove 20 to operate. Piece 1
The shutter plate 15 pivots largely in such a manner that the contact point between the rear end of 8A and the convex rail 19 is the center of rotation. When the pin 21 reaches the end of the arc portion 20b, the shutter plate 15 is biased in the forward direction by the elasticity of the spring 17, so that the pin 21 automatically fits into the stop portion 20c. Therefore, the shutter plate 15 is stable in the state of FIG. 7 even when the hand is released from the operation piece 18A. In this state, the prize ball falls because the ball hole 14 is open. on the other hand,
In order to return the shutter plate 15 to the original position, the front side of the operation piece 18A (the side of the ball hole 14) is manually pressed to insert the pin 21 into the through groove 2.
It may be moved to the straight line portion 20a of 0. Then,
Since the shutter plate 15 moves forward by the action of the spring 17, the ball hole 14 is closed.

As shown in FIG. 3, the outer cover 4 includes a swingable ashtray 12 and a display member 2 for appropriately displaying a trademark or the like.
2 and a switch button 23 for operating the micro switch 10 of the mounting base 3, and a handle hole 2 communicating with the through hole 9 of the mounting base 3 at a side position.
4 are formed. The ashtray 12 has swing shafts 2 on the left and right respectively.

The rocking shaft 25 is inserted into and attached to the square hole formed by the bearing long groove 28 and the shaft retainer 13 of the intermediate member 5. The protruding step 26 is used for extinguishing a cigarette.

[0012]

Second Embodiment FIGS. 8 and 9 show a second embodiment. FIG. 8 is an exploded perspective view of a ball removing device, and FIG. 9 is a longitudinal sectional view showing a main part. The ball removing device A according to the second embodiment uses the operation piece 18B as a stopper means. That is, the operation piece 18 </ b> B is swingably attached to the shutter plate 15 and is constantly urged upward by the spring 29. On the other hand, an engagement piece 30 for restricting the upward swing of the operation piece 18B extends from the lower edge of the front surface of the ball tray 11 of the middle member 5. The engagement piece 30 regulates the upward swing of the operation piece 18B at the forward position where the shutter plate 15 closes the ball removal hole 14, and controls the operation piece 18B at the ball removal position where the shutter plate 15 opens the ball removal hole 14. Figure 9
At the same time as the operation piece 18B is swung upward as indicated by the chain line, the front edge of the operation piece 18B is engaged with its own side edge to prevent the operation piece 18B from moving in the horizontal direction.

Therefore, when the shutter plate 15 is retracted for the ball removing operation, the operation piece 18B swings upward and engages with the side edge of the engaging piece 30 with the ball removing hole 14 substantially opened. . The shutter plate 15 does not move back even if the operator releases the operating piece 18B while the operating piece 18B and the engaging piece 30 are engaged. Then, after the ball removal is completed, the operation piece 18B
When is pressed with a finger, the operation piece 18B is disengaged from the engagement with the side edge of the engagement piece 30, so that the shutter plate 15 is automatically returned by the bias of the spring 17.

[0014]

Third Embodiment FIGS. 10 and 11 show a third embodiment. FIG. 10 is a partially enlarged longitudinal sectional view showing a ball removing device, and FIG. 11 is a partially enlarged longitudinal sectional view showing an operation state of FIG. is there. The third embodiment is obtained by further improving the second embodiment and adding an automatic releasing function of the stopper means. In the third embodiment, the engaging piece 30 fixedly hung on the ball tray 11 in the second embodiment is hung on the movable bottom wall 32 pivotally mounted on the ball tray 11 in the third embodiment. The movable bottom wall 32 has a distal end facing the inward concave portion 31 of the ball tray 11, is urged upward by a spring (not shown), and has an inward concave portion with no load as shown in FIG. 31 is in contact with the upper edge. On the other hand, as shown in FIG. 10, the operation piece 18 </ b> B is in a state in which the movable bottom wall 32 is in contact with the lower front edge of the ball tray 11 with the movable bottom wall 32 raised, so that the operation piece 18 </ b> B can freely move in the horizontal direction without contacting the engagement piece 30. Can slide.

Now, as shown in FIG. 11, the ball tray 11
When a prize ball accumulates, the front end of the movable bottom wall 32 is lowered by the application of spherical pressure to the movable bottom wall 32, so that the tip of the movable bottom wall 32 is supported by the lower edge of the inward concave portion 31. Then, the engaging piece 30 protrudes below the lower edge of the front surface of the ball tray 11 and pushes down the operating piece 18B. When the operation piece 18B is slid in this state,
As in the case of the second embodiment, the operation piece 18B is disengaged from the engagement piece 30 at the ball release position where the shutter plate 15 has substantially opened the ball release hole 14, and the operation piece 18B swings upward as shown by the chain line in FIG. Then, similarly to the second embodiment, the stopper means is in the operating state. Even when it is necessary to temporarily close the ball removal hole 14 due to replacement of the ball box or the like, the operation piece 18B may be pushed in as in the second embodiment.

Next, when there are no more prize balls on the ball tray 11, the movable bottom wall 32 returns to the state shown in FIG. 10, the engaging piece 30 rises, and the engagement with the operating piece 18B is released. As a result, the stopper means is automatically released, and the shutter plate 15 is moved back by the action of the spring 17. Thus, Example 3
Then, since the shutter plate 15 automatically moves back when the prize ball disappears from the ball tray 11, not only does the player not bother to release the stopper means by himself, but also the prize ball caused by forgetting to close the shutter plate 15. It is possible to prevent accidents such as scattering. Since there is a possibility that the stopper means is released from the movable bottom wall 32 in a state where the prize ball remains and is small, the prize ball may remain in the ball tray 11. However, since the number is very small, it does not matter much if it is necessary to support the operation piece 18B by hand while pulling out the remaining prize balls.

Although the embodiments have been described above, of course, the present invention is not limited to the above embodiments. For example, the operation pieces of the second and third embodiments may be divided into two in the front-rear direction, the front operation piece may be fixed to the shutter plate 15, and the rear operation piece may be a swing type as shown in FIG. If the sliding operation of the shutter plate 15 is performed only by the operation piece on the fixed side, there is no possibility that the movement of the operation piece on the swing side is obstructed by hand, and the operability is further improved. In addition to the case where the automatic release function of the stopper means is operated only by the ball pressure as in the third embodiment, the tilt state of the movable bottom wall 32 is detected by an electric sensor such as a micro switch, and the signal of the sensor is used. It is also possible to operate the solenoid and thereby electrically release the stopper means.

[0018]

As described above, in the ball removing device of the present invention, the function of the stopper means enables the ball removing operation without pressing the operation piece by hand, so that even if a lot of prize balls are extracted. The hands are not tired and both hands are not blocked even if the prize ball is pulled out while continuing the game, so that smoking and eating and drinking can be performed without difficulty.
