[0006]

Since the synthetic resin spring member is integrally molded with the valve control member or the mechanism plate or the accessory of the mechanism plate, the conventional metal winding spring is not required, and the valve control member can be assembled easily. It can be rationalized. Further, since the spring member is made of synthetic resin, there is no sharp portion such as the end portion of the metal winding spring, and the safety during work is high.

[0007]

First Embodiment A first embodiment of the present invention will be described below with reference to FIGS. 1 is a perspective view of an essential part showing the ball removing device, FIG. 2 is a rear view of the pachinko machine, FIG. 3 is a sectional view of the essential part, FIG. 4 is a sectional view taken along line YY of FIG. 3, and FIG. It is a perspective view showing a lever piece of a valve control member.

The ball removing device of the pachinko machine communicates with the ball passage 3 connecting the ball tank 1 and the ball releasing device 2, a ball outlet 4 opening in a part of the ball passage 3, and the ball outlet 4. Ball-out gutter 5
And a swingable valve member 6 that opens and closes the ball outlet 4, and a valve control member 7 that controls the movement of the valve member 6.

[0009] The valve member 6 has a substantially V-shape when viewed from the front, and the central bent portion is axially attached to the mechanism plate 8.
It is balanced to rotate clockwise in FIG. 3 under no load. Further, the valve member 6 is set to rotate counterclockwise as shown by the chain double-dashed line in FIG. 3 when a pachinko ball is placed on the upper surface.

On the other hand, the valve control member 7 is locked by a lock piece 71 axially attached to the mechanism plate 8 so as to be swingable in the same vertical plane as the valve member 6 and a bearing member 9 integral with the mechanism plate 8. Piece 7
1. The swing shaft 10 is configured to swing freely in a vertical plane orthogonal to 1.
It is a combined structure with the lever piece 72 axially attached by. The lock piece 71 and the lever piece 72 are linked to each other by a rod 72a integrally extending from the lever piece 72 engaged with a through hole 71a formed in the lock piece 71, and are driven by the swing of the lever piece 72. The lock piece 71 swings. The lock piece 71 has a step portion 71b at a right angle which engages with the lower end of the valve member 6 at the upper portion, and engages with the valve member 6 in the state shown by the solid line in FIG.
Lock in the closed position. The lever piece 72 is a molded product of synthetic resin, and as shown in FIG. 5, a shaft tubular portion 72b through which the swing shaft 10 passes, and a leaf spring-like spring member 16 protruding above the shaft tubular portion 72b. And a lever main body 72c which is located beside the spring member 16 and has the rod 72a, and a pin receiving plate 72d which projects laterally from the upper end of the lever main body 72c and faces the ball hole 12 of the front frame 11. Spring member 16
The fixed stopper 13 projecting from the mechanism plate 8 is engaged with the front face to restrict the movement. Therefore, when the lever main body 72c of the lever piece 72 is tilted toward the lock piece 71 side about the swing shaft 10, the spring member 16 is curved in an arch due to the engagement with the stopper 13, and the restoring force due to its elastic deformation. Then, the lever main body 72c returns to the original position.

Next, the operation of the ball removing device will be described.
As shown in the solid line in FIG.
The stepped portion 71b of No. 1 engages with the lower end of the valve member 6
Is locked in the closed position. Therefore, the pachinko ball flows through the upper surface of the valve member 6 toward the ball discharging device 2 side. In order to execute the ball removal of the pachinko ball from this state, first, as shown in FIG. 4, the operation pin 14 is inserted into the ball removal hole 12 of the front frame 11 and the pin receiving plate 72d of the lever piece 72 is pushed. Then, the lever main body 72c tilts toward the lock piece 71 side around the swing shaft 10. By this tilting of the lever main body 72c, the lock piece 71 tilts clockwise through the rod 72a as shown by the chain double-dashed line in FIG. 3 to unlock the valve member 6. Therefore, the ball member 6 is rotated by the ball pressure of the pachinko ball as shown by the chain double-dashed line in FIG.
From the ball to the gutter 5. Since the spring member 16 hits the stopper 13 and bends in an arch due to the tilt of the lever main body 72c, when the operation pin 14 is pulled out from the ball hole 12 and the lever main body 72c is released from the pressing, the elasticity of the spring member 16 causes the lever main body to move. 72c returns to the original position.

Next, when the ball removal is completed, the valve member 6 rotates clockwise in FIG. 3 due to its own weight balance,
The lower end of the lock rests on the lock piece 71. In this state, when the operation pin 14 is inserted into the ball hole 12 of the front frame 11 and the lever piece 72 is pushed once and then removed, the lock piece 71 tilts as shown by the two-dot chain line in FIG. Therefore, the lower end of the valve member 6 engages with the stepped portion 71b of the lock piece 71 at the moment when the stepped portion 71b of the lock piece 71 is lowered, and the lock state is established.

Although the first embodiment of the present invention has been described above, FIGS. 6A to 6C and 7 show another embodiment of the valve control member 7. That is, FIG. 6A shows the spring member 16 coupled to the upper end of the lever main body 72c.
6B shows the spring member 16 horizontally protruding from the lower edge of the shaft cylinder portion 72b, and the spring member 16 engages with the bottom of the bearing member 9 of the mechanism plate 8. Therefore, there is an advantage that it is not necessary to separately form the stopper 13. In addition, FIG. 6C shows a horizontal U at the lower end of the lever main body 72c.
The character-shaped spring member 16 is formed. If this structure is adopted, the lower end of the lever piece 72 may be screwed to the mechanism plate 8, and therefore the valve control member 7 can be more easily assembled. Further, in FIG. 7, the spring member 16 is formed on the lock piece 71 of the valve control member 7. With this configuration, the conventional metal lever piece 72 excluding the metal winding spring can be used as it is.

[0014]

Second Embodiment FIG. 8 shows a second embodiment, in which a leaf spring-shaped spring member 16 is integrally formed with the mechanism plate 8. In the second embodiment, the engaging piece 15 is provided on the side surface of the lever main body 72c.
Projectingly connects with the spring member 16.

[0015]

[Third Embodiment] FIG. 9 shows a third embodiment in which the bearing member 9 is separately provided as an accessory to the mechanism plate 8 and a spring member 16 is integrally formed on the bearing member 9. is there. When the configuration of the third embodiment is adopted, the mechanism plate 8 is made of a hard synthetic resin having high rigidity as in the conventional case, and the bearing member 9 is formed.
Only can be made of soft synthetic resin with excellent elasticity. In the third embodiment, the spring member 16 is directly engaged with the pin receiving plate 72d of the lever main body 72c.

Although the present invention has been described with reference to the first to third embodiments, the present invention is of course not limited to the above embodiments. For example, in Examples 1 to 3, the valve control member 7 has a combined structure of the lever piece 72 and the lock piece 71.
The valve control member 7 may have any form. Also,
When the lever piece 72 is made of synthetic resin, the pin receiving plate 7
It is also possible to attach a metal plate to the surface of 2d so as to enhance the sliding with the operation pin 14.

[0017]

In the ball removing device of the present invention, the spring member made of synthetic resin is integrally formed with the valve control member or the mechanism plate or the accessory part of the mechanism plate, so that the conventional metal winding spring is unnecessary. As a result, the assembling work of the ball removing device can be dramatically streamlined. Also, since the spring member is made of synthetic resin,
There is no sharp portion such as the end of the metal winding spring, and therefore, the safety at the time of work is high, and other excellent effects can be obtained.
