It is held by two support members 3 provided at the upper and lower corners of the side surface 1a, and the other is detachably mounted by two locking members 4 provided at the upper and lower corners of the inner side surface 1a of the gaming machine frame 1. The game board 2 is formed with a mounting recess 5 for allowing a part of the locking member 4 to pass through when attached to the gaming machine frame 1.

FIG. 2 shows details of the support member 3 and the locking member 4. The support member 3 includes two rear support pieces 11a and 11b and one front support piece 12, and sandwiches the inserted game board 2 with elasticity from the front and rear.
The locking member 4 includes a front clamping piece 42 that rotates along the game board surface on the support shaft 41, a rear clamping piece 43 that rotates together with the front clamping piece 42 along the back side of the game board, A spring 44A for urging the rear clamping piece 43 in the direction of the front clamping piece 42 is mounted. The lower end of the support shaft 41 is inserted into the mounting hole 13 of the gaming machine frame 1, and the upper end is It is screwed to the gaming machine frame 1 via the plate material 14.

  The front clamping piece 42 has the structure shown in FIG. 3, and includes a shaft portion 42a, a locking portion 42b extended to the shaft portion 42, a flat raised portion 42c slidably contacting the front of the game board, and the shaft portion 42a. An elastic piece 42d protruding in the circumferential direction, a fitting protrusion 42f, and a knob 42g are provided. In addition, an inclined surface 42e is formed on the front side of the flat bulging portion 42c when turning and tightening, so that the game board 2 can be smoothly tightened, and the flat bulging portion 42c provides a function of preventing loosening when tightening. .

Further, the rear clamping piece 43 has the structure shown in FIG. 4 and has a shaft portion 43a, a locking portion 43b extending in contact with the shaft portion 43, and an inclined surface 43c at the front side during tightening rotation. It includes a chevron 43d, a projection 43e that projects in a substantially perpendicular direction to the locking portion 43b, and a fitting recess 43f into which the fitting projection 42f is fitted.
Then, the front clamping piece 42 and the rear clamping piece 43 are combined so that the elastic piece 42d and the protrusion 43e are positioned in opposite directions, and attached to the support shaft 41 together with the spring 44A, so that one engagement A stop member 4 is provided.

In attaching the game board, first, the game board 2 is fitted into the gaming machine frame 1 as shown in FIG. In this state, both the front clamping piece 42 and the rear clamping piece 43 are upward, the elastic piece 42d is located outside the support shaft 41, and the protrusion 43e is located inside the support shaft 41.
Then, if the front clamping piece 42 is rotated, the rear clamping piece 43 is also rotated integrally, and the state shown in FIG. 7 is obtained through the state shown in FIG. 6, and the end of the game board 2 is moved forward from the front clamping piece. 42 and the rear clamping piece 43. Specifically, the game board without the locking member 4 loosening due to the flat bulging portion 42c of the front clamping piece 42 and the pinching protrusion 43d of the rear clamping piece 43 and the biasing of the spring 44A toward the front of the gaming board 2 2 is fixed. When the spring 44A presses the game board 2 forward, the game board 2 is fixed with its position in the front-rear direction set accurately.

Furthermore, the elastic piece 42d is brought into sliding contact with the side surface of the mounting recess 5 by the rotation of the front locking piece 42, and the protrusion 43e of the rear locking piece 43 is slidably contacted with the inner side surface 1a of the gaming machine frame 1. The elastic piece 42d presses the mounting recess 5 side surface of the game board 2 in the lateral direction. The protrusion 43e located on the opposite side prevents the support shaft 41 from being bent by the reaction force and contacts the inside of the gaming machine frame. Therefore, the position of the game board 2 in the left-right direction can be accurately set to a predetermined position.
According to the mounting structure of the gaming board 2 described above, after the gaming board 2 is inserted into the supporting member 3 and fitted into the gaming machine frame 1, the front clamping piece 42 of the locking member 4 is only rotated.

Further, as shown in FIG. 8, the game board 2 can be securely attached to the gaming machine frame 1 by properly setting the front and rear, left and right positions by arranging the gaming machine frame 1 at the four corners inside the gaming machine frame 1.

FIG. 9 is a view showing a game board mounting structure as a reference example , and the locking member 4 is rotated together with the front clamping piece 44 rotating along the gaming board surface and the front clamping piece 44. It consists of an eccentric cam 7 that moves, and a rear clamping piece 45 that is moved up and down by the eccentric cam 7. The front clamping piece 44 and the eccentric cam 7 are inserted into the support shaft 46 at a required interval with the first spring 9 interposed therebetween. Further, the eccentric pin 7 is inserted into the engagement hole 45 h of the rear clamping piece 45, and is urged by the second spring 6 in a direction (downward) perpendicular to the support shaft 46.

Before the game board 2 is clamped, the front clamping piece 44 and the eccentric cam 7 face upward, and the eccentric cam 7 pushes up the rear clamping piece 45 against the elastic force of the second spring 6. In this state, the gaming board 2 is set in the gaming machine frame 1.
If the front clamping piece 44 is rotated by 180 ° after the setting of the game board 2 is completed, the push-up of the eccentric cam 7 is released, and the rear clamping piece 45 is ejected by the second spring 6 and protrudes downward. Therefore, as shown in FIG. 10, the end portion of the game board 2 can be sandwiched between the front clamping piece 44 and the rear clamping piece 45.

  Here, the latching portion 45b of the rear clamping piece 45 has a flat front side and a rear side that is reduced in width toward the tip, and the gaming machine frame 1 has a corresponding biasing direction of the second spring 6. An inclined surface 15 is formed so that the distance from the back of the game board is narrow. Therefore, when the rear clamping piece 45 protrudes, the locking portion 45b slides on the inclined surface 15 and is pushed forward against the resilience of the first spring 9, thereby pressing the game board 2 forward. Therefore, the front and rear positions of the game board surface can be accurately positioned.

  In addition, since the elastic piece 44d extending in the circumferential direction is provided at the shaft portion of the front clamping piece 44, the elastic piece 44d moves across the side surface of the concave portion 5 for mounting the game board 2 when the front clamping piece 44 is rotated. Press in the direction. Therefore, the left and right positions of the game board 2 can be accurately positioned.
