Next, embodiments of the present invention will be described based on examples of the present invention. The present invention is not limited to the following examples and the like, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention.
[Example]
The overall structure of the pachinko machine 50 (bullet ball game machine) of this embodiment will be described with reference to FIGS.

  A front door frame 51 is arranged on the front surface of the pachinko machine 50 (FIGS. 2 and 3 show a state in which the front door frame 51 is removed). Specifically, the middle frame 58 is attached to the outer frame 1 using a hinge structure, and the front door frame 51 is attached to the middle frame 58 with a hinge structure.

  The front door frame 51 is provided with a window 52 for facing the game board 83 (shown in FIG. 1 is not equipped with a game board), and a glass plate for closing the window 52. Is mounted behind the window 52.

  Below the window 52, an upper plate 54 and a lower plate 55 are arranged so as to overlap each other, and a firing handle 56 is arranged on the right side of the lower plate 55. A key hole 59 for operating the lock mechanism is also attached to the front surface of the middle frame 58.

  The game board 83 has a plate shape, and an arc-shaped outer rail 85, a left inner rail 86, and a right inner rail 87 are attached to the front surface of the game board 83. The In addition, the game board 83 is provided with a mounting hole 88 used for mounting a center accessory (liquid crystal display device). Although not shown, holes for attaching various winning devices are also provided at positions away from the mounting holes 88, and the winning devices are attached to the game board 83.

The game board 83 is held by the middle frame 58. That is, the middle frame 58 corresponds to the game board holding frame.
The middle frame 58 is composed of two vertical sides 61 of an aluminum extruded product, and an upper horizontal member 62 and a lower horizontal member 63 made of synthetic resin. The game board 83 is held by supporting the end face and sandwiching the left and right sides of the game board 83 between the vertical sides 61. The lower horizontal member 63 is provided with a locking structure portion 63 a used for mounting the game board 83.

  As shown in FIGS. 4 to 7, the game board mounting structure for mounting the game board 83 to the middle frame 58 is the middle frame 58 (here, the upper horizontal member 62. ), An out-of-range decoration member 64 (clamping member) mounted on one side of the game board 83, and an operation member 66.

  The operation member 66 includes a columnar main shaft 71, an operation lever 72 connected to the rear end portion of the main shaft 71, and a locking piece 73 connected to the constricted tip of the main shaft 71. The locking piece 73 has a rectangular parallelepiped chamfered shape, and the cross-sectional shape perpendicular to the axis of the main shaft 71 is rectangular. The central portion of the main shaft 71 (the portion between the operation lever 72 and the constricted portion) is a sliding portion.

  The upper horizontal member 62 is provided with an oblong locking hole 67 that is vertically long (the height is larger than the horizontal width). The locking hole 67 is slightly larger than the outline dimension of the locking piece 73. If the longitudinal direction of the locking piece 73 is aligned with the vertical direction of the locking hole 67, the locking piece 73 is inserted into the locking hole 67. Can be passed. A locking step 68 is provided on the back surface of the upper horizontal member 62 adjacent to the locking hole 67. The locking step 68 is provided to lock the locking piece 73.

  The outer decorative member 64 is provided with an arcuate concave portion 74 including an upper arc portion 74a, a main arc portion 74b, and a vertical portion 74c connecting the ends thereof. The out-of-range decoration member 64 is brought into contact with the front surface of the game board 83 in a posture in which the upper arc portion 74a is in contact with the outer surface of the upper end portion of the outer rail 85 and the main arc portion 74b is in contact with the outer surface of the right inner rail 87. And is fixed to the game board 83 by screws passing through the screw holes.

  The out-of-range decoration member 64 is attached to the game board 83 so as to cover the outside of the right inner rail 87 of the game board 83 (that is, the portion outside the game area 84). The lower side is straight and overlaps each side of the attached game board 83.

  Concave portions 75 and 76 are provided at the upper and lower corners of the outside decorative member 64. Each of the recessed portions 75 and 76 is provided with a through-opening 77 having a shape in which an arc-shaped bearing portion 77 b is added to a long hole portion 77 a having the same shape as the locking hole 67. Further, an arc-shaped protrusion 78 concentric with the bearing portion 77 b is provided in the vicinity of the through opening 77.

  A locking piece 73 can be inserted and passed through the through-opening 77 in the same manner as the locking hole 67 described above. Further, when the locking piece 73 is inserted and passed, the main shaft 71 is fitted into the bearing portion 77b, and in this state, the main shaft 71 can be slid and rotated using the bearing portion 77b as a bearing.

  The locking piece 73 and the tip of the main shaft 71 protrude from the through opening 77 to the back of the outer decorative member 64, but the game board 83 is provided with a notch 89 at a position behind the through opening 77. The locking piece 73 and the main shaft 71 are not hindered from protruding.

The operation of attaching the game board 83 to the middle frame 58 is performed as follows.
First, the elongated hole 77a of the through-opening 77 is engaged with the game board 83 sandwiched between the outside decoration member 64 (clamping member) and the upper horizontal member 62 that is a part of the middle frame 58 (game board holding frame). The out-of-range decorative member 64, the game board 83, and the middle frame 58 (upper horizontal member 62) are aligned so that the position overlaps the stop hole 67.

  Next, the locking piece 73 and the main shaft 71 are inserted into the long hole portion 77a with the locking piece 73 as the head, and the locking piece 73 having passed through the long hole portion 77a has the locking hole 67. Push in until it passes and reaches behind the locking hole 67. Then, the locking piece 73 protrudes behind the locking hole 67, and the main shaft 71 is fitted into the bearing portion 77b.

  Then, when the locking piece 73 is rotated approximately 90 degrees by sliding and rotating the main shaft 71 fitted in the bearing portion 77b via the operation lever 72, the locking piece 73 rides on the locking step 68, The operation lever 72 rides on the arc-shaped protrusion 78. As a result, the outer decorative member 64, the game board 83, and the upper horizontal member 62 are sandwiched between the operation lever 72 and the locking piece 73.

Further, although the detailed description is omitted, the same operation is performed on the locking structure portion 63a of the lower horizontal member 63.
Thereby, the game board 83 is attached to the middle frame 58.

  On the other hand, when the operation board 72 is rotated 90 degrees in the state opposite to the above in the state where the game board 83 is attached to the middle frame 58, the locking between the locking piece 73 and the locking level 68 is released. Therefore, the operation member 66 can be extracted. If the operation member 66 is removed, the game board 83 can be removed from the middle frame 58.

  As described above, the game board mounting structure of this embodiment is simple in structure and easy to operate. Further, since the operation member 66 is inserted after the game board 83 is fitted to the middle frame 58, the workability of fitting and positioning the game board 83 is improved.
