  Subsequently, the structure of the locking members 50a and 50b and the engaging portions 40a and 40b constituting the fixing device for fixing the game board 3 and the front frame 2 will be described in detail with reference to FIGS. 2 and 4 to 7. . Since the upper locking member 50a and the lower locking member 50b have the same configuration, only the upper locking member 50a will be described here, and the description of the lower locking member 50b will be omitted. Similarly, although the upper engagement portion 40a and the lower engagement portion 40b have slightly different shapes, they have a very similar configuration. Therefore, only the upper engagement portion 40a will be described here, and the lower engagement portion 40b will be described. Description of is omitted.

  The upper locking member 50a made of a resinous material is a rod-shaped shaft portion 52a that is rotatably supported at the upper right corner of the game board 3, and one end side of this shaft portion 52a (the front side of the game board 3). It is comprised by the knob part 51a attached, and the latching piece 53a attached to the other end side (rear surface side of the game board 3) of the axial part 52a. The knob 51a has a size that can be grasped by an operator's fingers and is formed of an elongated block, and the locking piece 53a has a similar shape that is slightly smaller than the knob 51a. And the knob part 51a and the locking piece 53a are each attached to the edge part of the axial part 52a so that it may become line symmetrical about the axis line of the axial part 52a. Therefore, when the shaft portion 52a is oriented in the horizontal direction, the upper locking member 50a has a substantially H shape due to the shaft portion 52a, the knob portion 51a, and the locking piece 53a.

  It should be noted that when the knob portion 51a is in the horizontal direction, the game board 3 is fixed to the front frame 2, and when the knob portion 51a is in the vertical direction, the game is played with the front frame 2. This is the release position for releasing the fixation with the panel 3. Since the upper locking member 50a has the shape described above, the fixed position and the release position are switched each time the knob 51a is rotated 90 degrees.

  On the other hand, the upper engaging portion 40a is made of a resinous material, and has a wall portion 41a formed in a substantially U shape with the lower side opened in front view, as shown in FIGS. An opening 42a is formed inside the portion 41a. That is, the inner part of the wall 41a bent in a U-shape is the opening 42a. The opening 42a is an opening that is large enough to insert a portion (that is, half of the block) on one side of the locking piece 53a having an elongated block shape with the axis of the shaft 52a as the center. When the locking piece 53a is inserted into the opening 42a and the knob 52a is turned, the front surface of the locking piece 53a is engaged with the rear surface of the wall 41a as shown in FIG. Thereby, the game board 3 is fixed inside the front frame 2 so as not to move in the front-rear direction.

  Here, in order to attach the game board 3 to the inside (inside) of the front frame 2 without rattling, the outer shape of the game board 3 is manufactured with a plus tolerance dimension, and the game board 3 of the front frame 2 is attached. Parts are manufactured with negative tolerance dimensions. Therefore, when the game board 3 is attached to the front frame 2 and the locking piece 53a is inserted into the opening 42a and the knob 51a is rotated clockwise as viewed from the front side, The tip of the locking piece 53a comes into contact with the opposite side (right side) of the front frame 2 to the hinge 25, and the knob is moved to the position where the game board 3 is fixed, that is, the locking piece 53a is horizontal. There may be cases where 52a cannot be turned. Therefore, in this embodiment, the wall 41a-1 opposite to the hinge 25 in the wall 41a is formed to be bent by the pressing force accompanying the rotation of the locking piece 53a.

  With this configuration, when the knob portion 51a is rotated after the game board 3 is attached to the front frame 2, the locking piece 53a is brought to the wall surface 41a on the side opposite to the hinge of the wall portion 41a. -1 is engaged with the rear surface of the wall 41a while being pressed and bent. Therefore, the game board 3 can be reliably fixed to the front frame 2 without loosening in any of the front, rear, left and right directions.

  Next, how much the space on the rear side of the game board 3 of the present embodiment has been expanded will be described in comparison with a conventional example. First, the length between the upper engaging portion 40a and the lower engaging portion 40b (allowable dimension for mounting electrical components) in the present embodiment is L1, as shown in FIG.

  On the other hand, FIGS. 8 to 11 show the structure of the pachinko machine P2 in which the upper locking member 50a and the lower locking member 50b of the pachinko machine P according to this embodiment are attached to the front frame 2 as in the conventional example. ing. In the pachinko machine P2, the upper locking member 50a and the lower locking member 50b are provided on the front frame 2, and the upper engagement portion 40a and the lower engagement portion 40b are provided on the game board 3. Therefore, a boss 70a that rotatably supports the upper locking member 50a is required above the front frame 2, and a boss 70b that rotatably supports the lower locking member 40b is required below the front frame 2. . The boss 70a needs to have a shape larger than the rotation radius of the locking piece 53a in order to grasp the knob 51a and rotate the locking piece 53a around the shaft portion 52a by 360 degrees. The same applies to the boss 70b. Accordingly, in the case of the structure in which the upper locking member 50a and the lower locking member 50b are attached to the front frame 2 as in the conventional example, as shown in FIG. 10, an extra space by the length C1 is provided because the boss 70a is provided. Is required. Further, as shown in FIG. 11, since the boss 70b is provided, an extra space by the length C2 is required.

  Therefore, as shown in FIG. 12, the pachinko machine P2 in which the upper locking member 50a and the lower locking member 50b are attached to the front frame 2 as in the conventional example is provided with the electrical component U including the liquid crystal display device 34. Therefore, only the length L2 can be secured as the vertical space in which the electric component can be attached, that is, the allowable attachment dimension of the electrical component. Here, as shown in FIG. 12, since L1 = L2 + C1 + C2, the allowable attachment dimension L1 of the electrical parts of the pachinko machine P according to this embodiment is the pachinko with the locking members 50a, 50b attached as in the conventional example. This is longer by C1 + C2 than the allowable mounting dimension L2 of the electrical component of the machine P2. Accordingly, the pachinko machine P according to the present embodiment has room for the length of C1 + C2, so that even a liquid crystal display device that has recently increased in size has no particular design change. It can be attached to the rear surface.

  As described above, according to the pachinko machine P according to the present embodiment, the upper locking member 50a and the lower locking member 50b are formed at the corners formed on the upper and lower sides of the side opposite to the hinge of the game board 3, respectively. Since the upper engagement portion 40a and the lower engagement portion 40b that engage with these are provided in the front frame 2, the space on the rear surface side of the game board 3 is extra L1−L2 (ie, C1 + C2). It can be secured. Therefore, even if the large-sized liquid crystal display device 34 is mounted as it is at the height position where the liquid crystal display device 34 has been mounted, it does not interfere with the engaging portions 40a and 40b. That is, it is not necessary to make a significant design change in order to attach the liquid crystal display device 34 to the rear surface of the game board 3. Further, since the wall portions 41a-1 and 41b-1 on the anti-hinge side are bent, the game board 3 is held in the front frame 2 without loosening in any of the front, rear, left and right directions.
