Thus, the game board fixing fastener 9 can be used continuously without replacement.
[0019]
On the other hand, the rear surface 3a of the gaming board mounting frame 3 formed in a hollow shape is provided with a locking hole 43 for engaging the locking piece 24 at a position facing the game board fixing fastener 9. In the present embodiment, the game board mounting frame 3 is formed integrally with the front frame 2, but may be formed separately.
[0020]
In the game board fixing device having the above-described configuration, the lever member 12 of the game board fixing fastener 9 is rotated to the tightening release position shown by the chain line in FIG. 6, and the locking piece 24 of the link member 13 is opened. The mechanism plate 8 is brought into close contact with the back surface of the game board 4 while being moved to an upper position that does not protrude from the game board 16.
[0021]
When the lever member 12 is rotated from this state to the tightening position shown by the solid line in FIG. 6, the link member 13 moves through the long holes 17 and 17 via the guide pins 25 and 25, and the linkage pins 20 and 20. As a result of this rotation, the locking piece 24 engages with the locking hole 43. As a result, the game board mounting frame 3 is drawn and the mechanism plate 8 is moved to the back of the game board 4. So that the game board 4 can be firmly fixed to the game board mounting frame 3. Moreover, it can fix still more reliably by providing the latching protrusion 44 and the latching protrusion 45 in the opening end front surface of the latching hole 43, and the front-end | tip of the latching piece 24, respectively. Reference numeral 46 denotes a rotation restricting piece for restricting the rotation of the lever member 12.
[0022]

As shown in FIG. 7, the game board fixing fastener 9A is composed of three members: a frame member 11A, a lever member 12A, and a link member 13A. The frame member 11A has the same shape as the previous embodiment.
[0023]
The lever member 12A has substantially the same shape as that of the previous embodiment, and a hook-like locking piece 48 facing the opening 16 is provided on the front surface side of the fitting recess 21.
[0024]
The link member 13 </ b> A is formed in a plane U shape having arm pieces 23, 23 on both sides of the cylindrical portion 22.
[0025]
When the mechanism plate 8 is brought into close contact with the back surface of the game board 4 and the lever member 12A is rotated from the chain line in FIG. 8 to the tightening position indicated by the solid line, the link member 13A is elongated through the guide pins 25 and 25. While moving 17, 17, the linking pins 20, 20 are rotated as fulcrums, and with this rotation, the locking pieces 48 are engaged with the locking holes 43, and the game board 4 is securely fixed.
[0026]
Further, as shown in FIG. 9, a rib-shaped guide portion 49 is provided integrally on the lower surface of the locking piece 48 of the lever member 12 </ b> A to reinforce the locking piece 48, and supports the lower end of the locking hole 43. I am doing so. This reliably prevents the lever member 12A from inadvertently rotating in the tightening release direction due to the weight of the mechanism plate.
[0027]
As shown in FIG. 10, the same effect as that of the guide portion 49 is obtained by providing the guide pieces 50, 50 on the link member 13 </ b> A.
[0028]
In addition, as shown in FIG. 11, by providing a hook-like locking piece 51 instead of the guide piece 50, the fixing is further ensured and stabilized.
