Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a mechanism plate arranged on the back surface of a game board of a pachinko machine.

[Prior Art] A general pachinko machine is, for example, the actual exploitation Sho 55-65083.
As disclosed in the issue, the mechanism plate integrally provided with a prize ball discharge device, a discharge gutter of the prize ball, or a ball gathering for collecting and aligning the safe balls in the winning opening is the back surface of the game board. Installed on.

The mechanism plate of Japanese Utility Model Laid-Open No. Sho 55-65083 has a large recess formed in the ball pulling itself so as to completely cover a large prize winning device.

[Problems to be Solved by the Invention] According to the above-mentioned conventional technique, since the recess for ball shifting is integrated with the mechanism plate, the mechanism plate is adjusted every time adjustment or repair of the winning device or ball clogging in the ball shifting. There was a drawback that it was difficult to use because it had to open the whole.

On the other hand, in Japanese Utility Model Laid-Open No. 55-51266, a window hole is formed in a ball-pulling manner, and the window hole is covered with a detachable lid plate. In this case, although there is no problem as described above, Since a screw or the like is used to fix the cover plate, there is a problem that it takes time to attach and detach the cover plate.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention forms an opening in substantially the entire surface of the ball pulling portion of the mechanism plate, and covers a cover body so as to cover the opening. The cover body is formed in a box frame shape so that a wide space is provided between the cover body and the back surface of the game board.
Further, the cover body is detachably fixed by the engagement of the rotatable locking claw provided on the mechanism plate and the engaging projection piece provided on the cover body. A pin that slidably contacts the outer periphery of the piece is provided in a protruding manner, and the engaging protrusion has an outer peripheral shape that gradually pulls the pin outward as the pin of the locking claw comes into contact with the outer periphery of the engaging protrusion and rotates. A mechanism board for a pachinko machine having a configuration in which a recessed portion into which a pin is fitted is provided at an end point portion.

[Operation] Even if the rear part of the winning device is projected on the back surface of the game board due to the increase in size of the winning device, the cover body is formed into a box frame shape to form a wide space portion, so that it can be accommodated in the cover body comfortably.

Moreover, since the cover body is fixed by the engagement of the engaging claw and the engaging projection piece, the cover body can be easily attached and detached without using a tool such as a driver.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

The pachinko machine 1 is a well-known device in which a game board 4 is mounted inside a window hole 3 opened in the front frame 2, and a winning device 6 and the like are mounted on a game portion 4a surrounded by a guide rail 5 on the surface of the game board 4. It is a structure.

The mechanism plate 7 is superposed on the back surface of the game plate 4, and one longitudinal side is pivotally supported on the main body side of the pachinko machine 1 so that it can be opened and closed. On the mechanism plate 7, a ball tank 8 for storing the prize balls, a prize ball discharging device 9, a discharge gutter 10 for the prize balls, or a ball gathering 11 for collecting and aligning the safe balls that have entered the winning holes. A safe sphere processing device 12 for guiding the safe sphere 11 and activating the prize sphere discharging device 9 is provided.

Then, a large opening 13 is formed on substantially the entire surface of the ball pulling 11 of the mechanism plate 7.
And standing walls 14 project from the upper edge and both side edges of the opening 13. The box-frame-shaped cover body 15 has a size and shape that fits around the outer periphery of the standing wall 14. The cover body 15 has an appropriate depth, and a wide space 16 is formed between the cover body 15 and the game board 4 in a state of covering the opening 13 of the ball gathering 11. In addition, ball gathering
An inner cover 11 a is attached to the game board 4 in order to prevent the safe ball from jumping into the cover body 15.

Next, the fixing structure of the cover body 15 and the mechanism plate 7 will be described. Upward projecting pieces 17, 17 ... Are formed at appropriate intervals on the standing wall 14 at the upper edge of the opening 13, and the other cover body 15 The upper edge is formed with through holes 18, 18 ... Fitting to the upward projecting piece 17, and the upward projecting piece is fitted with the cover body 15 fitted to the standing wall 14.
17 and the through hole 18 are engaged.

On the other hand, the lower side of the cover body 15 is detachably fixed by the engagement of the rotatable locking claw 19 provided on the mechanism plate 7 and the engaging projection piece 20 provided on the cover body 15. The locking claw 19 is the mechanism plate 7
A tubular portion 22 is rotatably supported by a shaft 21 protruding from the
A pin 24 is further projected from an arm 23 projecting from the upper end of 22. On the other hand, the engaging projection 20 of the cover body 15 is erected on a mounting piece 25 extending vertically from the lower edge of the cover body 15, and its shape is the center of the tubular portion 22 of the locking claw 19. It has a 1/4 arc shape that is slightly eccentric to the shaft, and the pin 24 of the locking claw 19
The pin 24 gradually pulls outward (in the normal direction) as it abuts on the engaging projection 20 and rotates. The engaging projection 20 further includes a pin of the locking claw 19 at the end point of the top thereof.
There is a recess 26 into which 24 fits.

In the drawing, 27 is a long hole for separation provided in the cover body 15, particularly in the case of a large prize winning device or the like, the portion surrounded by the long hole is cut off and the rear part of the prize winning device is projected from this opening. It is a thing.

The present invention is constructed as described above. To mount the cover body 15 on the mechanism plate 7, first, the through hole 18 of the cover body 15 is fitted into the upward protruding piece 17 of the upper edge of the opening 13 so that the opening 13 of the opening 13 can be fitted. The cover body 15 is fitted to the standing wall 14. Then, rotate the locking claw 19 to rotate the pin.
When 24 is brought into contact with the engaging projection 20 and further rotated, the engaging projection 20 and the pin 24 rub strongly against each other, and the locking claw 19 receives a pulling action. When the pin 24 reaches the recess 26, the elasticity of the synthetic resin causes the pin 24 to fit into the recess 26 and be stabilized. When removing the cover body 15, the reverse operation may be performed.

In this embodiment, the locking claw 19 is provided on the mechanism plate 7 side and the engaging projection 20 is provided on the cover body 15 side, but the same effect can be obtained even if they are reversed.

[Effect of the Invention] As described above, according to the present invention, the large opening 13 is formed in the ball pulling 11 of the mechanism plate 7, and the box frame-shaped cover body 15 is attached to the opening 13, so that the game Wide space between board 4
16 can be made and large prize winning devices can be stored easily. And since this space part 16 extends over substantially the entire surface of the ball gathering 11, it can be sufficiently covered wherever the prize winning device 6 is attached.

Further, since the mechanism plate 7 and the cover body 15 are coupled by engaging the locking claws 19 and the engaging projections 20, they can be easily attached and detached, and tools such as a driver are not required, which contributes to improvement of usability. It is a thing.
