A more detailed description of the game board fixing fastener 9 is described in the specification of Japanese Utility Model Application No. 3-92228 filed by the present applicant.

Thus, the main body frame 11 of the game board fixing fastener 9 is integrally provided with a locking piece 27 having an opening groove 26 at the lower end of the bottom portion 14 thereof. Left and right side walls 15a, 15b are provided on the upper end of the bottom portion 14 of the main body frame 11.
A flange piece 14a is formed so as to protrude upward from the upper end thereof, and a bag-shaped fitting portion 28 having a bottom surface and an inner side surface opened at the flange piece 14a portion. It is preferable that the locking piece 27 is formed in a shape that is gradually curved in an arc shape. This is to ensure that the mechanism plate 8 is smoothly inserted into the insertion gap 30b formed in the mounting portion 10 described later.

On the other hand, as shown in FIG. 3, supporting portions 29a and 29b are provided on the mounting portions 10 and 10 of the mechanism plate 8 at upper and lower positions so as to face each other. Gaps 30a, 30b between the upper surface of
Are formed respectively. Then, one support piece 29
b has a cylindrical projection 31 so as to be positioned within the insertion gap 30b.
Is provided. The insertion gaps 30a and 30b are formed to have the same thickness as the locking pieces 27 of the body frame 11 and the thickness of the flange pieces 14a.

Further, a main body frame 11 of the fastener 9 is provided on the mounting portions 10, 10, and a side wall 15 located inside the main body frame 11.
a, and a side wall 15 positioned outside the main body frame 11 in a state where the main body frame 11 is in contact with the frame piece 32.
An engagement protrusion 33 is provided which abuts on b. The upper surface of the engagement projection 33 is formed as a tapered surface 34 that extends inward from the end of the mounting portion 10.

In the mounting structure of the game board fixing fastener 9 in the pachinko machine configured as described above, the mounting of the game board fixing fastener 9 is first formed on the mechanism plate 8 as shown by a chain line in FIG. The locking piece 27 of the game board fixing fastener 9 is inserted into the insertion gap 30b of the mounting portion 10 and the cylindrical projection 31 is formed.
Into the opening groove 26. As a result, the game board fixing fastener 9 can be rotated about the cylindrical projection 31 as a fulcrum.

Next, when the fixing fastener 9 is rotated clockwise from the state shown by the dashed line in FIG. 5 so that the upper end of the flange piece 14a is pushed into the insertion gap 30a, the side wall 15a, 15b is closed. The lower edge gets over the engagement protrusion 33 while contacting the tapered surface 34 of the engagement protrusion 33, and the side surfaces of the side walls 15 a and 15 b are formed on the frame piece 32 and the engagement protrusion 33 as shown in the solid line in FIG. It will adhere. Thereby, the lateral displacement of the game board fixing fastener 9 is suppressed by the frame piece 32 and the engagement projection 33, and the support piece 29

In this embodiment, as shown in FIG. 6, the engaging projection 33 can pass through the lower edge of the side wall 15a located inside the game board fixing fastener 9. A notch 35 is formed at the bottom. The formation of the notch 35 allows the contact with the engagement protrusion 33 to be performed only on the outer side wall 15b, thereby facilitating the mounting of the game board fixing fastener 9.

The mounting portion 10 of the mechanism plate 8 has a cylindrical projection 3 fitted to the bag-shaped fitting portion 28 of the game board fixing fastener 9.
6 are protrudingly provided. The fitting portion 28 and the cylindrical protrusion 36
For example, when the upper support piece 29a is broken,
By tightening a screw from the screw insertion hole 37 of the fitting portion 28 to the center screw hole 38 of the cylindrical projection 36, the game board fixing fastener 9 is provided.
It is intended to enable continuous use without replacement.

As shown in FIG. 6, the mounting portion 1 of the mechanism plate 8
0 has an opening 40 through which the fixture 39 fixed to the game board mounting frame 3 faces when the game board fixing fastener 9 is mounted. In the state where the mechanism plate 8 is in close contact with the back surface of the game board 4, the engaging portion 21 of the engaging member 13 of the game board fixing fastener 9 is attached to the tip of the fixing metal 39.
A groove 41 is formed in which the groove 41 engages.

Therefore, by rotating the lever 12 of the game board fixing fastener 9 from the chain line position in FIG. 6 to the solid line position in FIG. Along the groove 41 of the fixture 39
Engages. As a result, the fixing plate 39 is drawn, and at the same time, the mechanism plate 8 is used for the counter operation of the game plate 4.
The game board 4 can be firmly fixed by strongly pressing against the back surface of the game board 4.

FIG. 8 shows another embodiment, in which notches 42, 42 are provided along both sides of the engaging projections 33 formed on the mounting portion 10 of the mechanism plate 8, so that the engaging projections 33 are provided. Is made to have elasticity. With this configuration, when the game board fixing fastener 9 is attached to the mechanism plate 8, even if the engagement protrusion 33 is pressed down by the lower edge of the side wall 15 b of the main body frame 11, the escape becomes easy. Can be installed with light working force.

In FIG. 1, reference numeral 43 denotes a game board fixing fastener mounted on the lower central portion of the mechanism plate 8, and the fastener 43 is formed on the mechanism plate 8 as shown in FIG. By being fitted into the fitting concave portion 44, the positioning member is accurately positioned with respect to the fixing bracket 45, and the insertion piece 47 formed at the upper part of the main body frame 46 and the elastic piece 48 formed at the lower part.
Are engaged with the insertion groove 49 and the engagement hole 50 of the fitting concave portion 44, respectively, so as to be firmly fixed.
