Then, a first fastening part 78a for fastening the movable shaft unit 60 to the storage empty part 65, and a second fastening part 78b for fastening the movable shaft unit 60 and the pivot support end reinforcing plate 52 in an overlapped state. Thus, the shaft support end reinforcing plate 52 can be attached with the movable shaft unit 60 attached in advance. Therefore, the operation guide groove 91 can be positioned in accordance with the position of the operation portion 75 of the movable shaft unit 60 that is positioned in advance, and the movable shaft unit 60 and the operation shaft 75 can be prevented from interfering with the edge of the operation guide groove 91. The shaft support end reinforcing plate 52 can be assembled.

  The pivot end reinforcing plate 52 is opened with an opening hole 113 at the rear of the fastening member 112 that fastens the base member 22 and the lower decorative unit 26 so that the fastening member 112 can sufficiently pass therethrough. ing. Accordingly, when the lower decorative unit 26 needs to be replaced, the lower decorative unit 26 can be easily moved forward from the front cover member 8 with the shaft support end reinforcing plate 52 attached to the base member 22. Can be removed and the replacement work can be performed quickly.

  In order to attach the front cover member 8 provided with the movable shaft unit 60 and the fixed bearing portion 61 configured as described above to the front frame 3, first, the front cover member 8 is slightly tilted so that the rotation free end side is lowered. The fixed shaft member 94 on the side of the front frame 3 is inserted into the fixed bearing hole 95 of the fixed bearing portion 61 in a state of being opened and opened with respect to the front frame 3. Further, the movable shaft member 66 and the operation portion 75 of the movable shaft unit 60 are rotated (FIGS. 17A and 17B), and the operation portion 75 is pulled out to the position where it can be easily operated from the operation storage space portion 81. It protrudes and enters the operation guide groove 91 (FIGS. 17C and 17D). Then, the operation portion 75 is lowered downward while resisting the urging force of the coil spring 68 in this approach state. Then, the operation portion 75 is guided in the insertion / removal operation direction by the operation guide groove 91, and the upper end of the shaft portion 74 is retracted from the engagement space portion 79 (FIGS. 17E and 17F).

  Then, with the shaft portion 74 retracted from the engagement space portion 79, the inclination of the front cover member 8 is returned and the bearing portion 62 of the front frame 3 is inserted into the engagement space portion 79 (FIG. 18 (a), (B)) The upper end of the shaft portion 74 is aligned with the bearing hole 93 of the bearing portion 62. Even if the bearing portion 62 enters the engagement space portion 79 during the alignment between the shaft portion 74 and the bearing hole 93, the bearing portion 62 is engaged by the collision preventing portion 70 of the shaft support member 67. It is prevented from colliding with the surface of the base member 22 located on the back side of the joint space 79. Therefore, when the bearing portion 62 is fitted to the movable shaft unit 60, the bearing portion 62 collides with the back side of the movable shaft unit 60 in the housing empty portion 65, thereby eliminating the disadvantage that the base member 22 is damaged. can do.

  When the position of the shaft portion 74 is aligned with the bearing hole 93, the operation portion 75 is released. Then, the movable shaft member 66 moves upward (direction in which the shaft portion 74 is inserted into the bearing hole 93) by the urging force of the coil spring 68, and the shaft portion 74 is inserted into the bearing hole 93. Accordingly, the front cover member 8 is pivotally supported on the front frame 3 via the hinge mechanism 31 and the lower pivot support mechanism 32. The movable shaft member 66 stops when the stopper 76 contacts the lower surface of the upper support surface portion 67b. Then, the operation unit 75 stops at the communication portion between the operation guide groove 91 and the advance / retreat passage 90 (FIGS. 18C and 18D), and the tip of the operation unit 75 is placed on the other side of the front surface of the front frame 3. Projecting from the shaft support end reinforcing plate 52 toward the side opposite to the side on which the bearing portion 62 is provided (lower left side in FIG. 19B), it is disposed in an inclined state with respect to the front surface of the front frame 3. .

  When the front cover member 8 is closed with respect to the front frame 3 while the operation unit 75 is arranged as described above, the operation unit 75 abuts the front end of the front cover member 8 on the front frame 3. When the front cover member 8 is further closed in this contact state, the operation unit 75 is pushed by the front frame 3 and rotates toward the front cover member 8 (FIGS. 19A and 19B). Therefore, when the front cover member 8 is closed with respect to the front frame 3, it is possible to eliminate the inconvenience that the operation unit 75 and the front frame 3 are pressed against each other and damaged. Further, when the front cover member 8 is sufficiently closed with respect to the front frame 3, the operation unit 75 is in contact with the side surface (the outer peripheral surface extending in the horizontal direction) of the operation unit 75 on the front surface of the front frame 3. Is stored in the operation storage space 81 (FIGS. 19C and 19D).

  Further, the movable shaft member 66 can store the operation portion 75 in the operation storage space portion 81. Moreover, since the stopper 76 is pressed against the upper support surface portion 67b by the coil spring 68, when the front cover member 8 once closed is opened again with respect to the front frame 3, the movable shaft member 66 operates the operation portion 75. The shaft support member 67 and the front cover member 8 can be rotated together while being stored in the storage space 81. Therefore, when the front cover member 8 is not attached / detached, the operation portion 75 can be stored in the operation storage space portion 81, the wiring of the pachinko gaming machine 1 is caught, or the operator bumps the hand. Inconvenience can be prevented.

  When it is necessary to remove the front cover member 8, the front cover member 8 is first opened widely, and the movable shaft member 66 and the operation unit 75 are rotated in this open state, and the operation unit 75 is pulled out from the operation storage space 81. The shaft support end reinforcing plate 52 is disposed so as to protrude rearward. Then, the operation unit 75 enters the operation guide groove 91 and can move in the insertion / removal operation direction. If the operation part 75 can be moved in the insertion / removal operation direction, the operation part 75 is lowered downward along the insertion / removal operation direction, and the shaft part 74 is pulled out from the bearing hole 93 of the bearing part 62. Then, the front cover member 8 is tilted while the pulled-out state is maintained, and the bearing portion 62 is detached from the engagement space portion 79. Then, the front cover member 8 can be lifted and the fixed shaft member 94 can be removed from the fixed bearing portion 61, whereby the front cover member 8 can be removed from the front frame 3.

  As described above, in the attaching and removing operations of the front cover member 8, the movable shaft unit 60 inserts and removes the movable shaft member 66 after protruding the operation portion 75 of the movable shaft member 66 to a position where it can be easily operated. Can do. Accordingly, the front cover member 8 can be easily attached and detached, and the efficiency of assembly work and maintenance work can be improved and the burden can be reduced.
