When the glass plates 9 are fixed in this manner, the peripheral portions of both glass plates 9 are in close contact with the peripheral holding frame 45, and the space between the two glass plates 9 communicates with the outside through the top through hole. Therefore, the inside of both glass plates 9 is hardly fogged, and if the desiccant is stored in the desiccant storage chamber 48, the glass plate 9 can be more reliably prevented from fogging.

Next, the back surface member 24 attached to the bottom of the back surface of the door body 22 will be described.
As shown in FIG. 8, the back member 24 is a member made of synthetic resin that is horizontally long when viewed from the front side of the pachinko machine 1, and has a flat upper surface portion 61 that extends from the upper end edge of the horizontally long back surface portion 60 toward the front. It is formed horizontally, the lower surface portion 62 is formed from the lower end edge of the back surface portion 60 toward the front, and the reinforcing rib 63 is integrally formed in the vertical direction so as to connect the upper surface portion 61 and the lower surface portion 62. On the front side of the upper surface portion 61, an arrangement notch portion 64 having a size that can accommodate and arrange the load support portion 29 is formed at a position corresponding to the load support portion 29, and the left and right sides that are closer to the outside of each load support portion 29. Further, an engagement notch 65 for constituting the opening of the engagement hole 55 is formed in a recess (dent) shape with the upper surface and the front surface opened. As described above, the engagement notch portion 65 is a concave portion in an upper open state that becomes an engagement hole 55 that regulates the position of the lower portion of the glass unit 23 in the front-rear and left-right directions with the back member 24 attached to the door body 22. The left and right side surfaces are tapered such that the left and right widths become narrower as they fall from top to bottom, and the rear surface is tapered so that the front and rear widths become narrower as they fall from top to bottom. ing. That is, the left wall, the right wall, and the rear wall of the engagement hole 55 are formed in an inwardly inclined state.

  In order to attach the back member 24 having such a configuration to the back side of the open / close door body 22, as shown in FIG. 9, the load support portion 29 is inserted into the insertion hole of the lower reinforcing plate 35 and the through hole 66 is inserted. With the boss 67 on the door body 22 side inserted, the lower reinforcing plate 35 is brought into contact with the back surface of the door body 22, and the back member 24 is attached from behind the lower reinforcing plate 35. In this case, the back surface member 24 is brought into contact with the back surface of the lower reinforcing plate 35 in a state where the load support portion 29 is accommodated in the disposition notch portion 64 with the disposition notch portion 64 of the back surface member 24 facing the back surface of the open / close door 8. A screw is inserted from the screw hole 68 formed in the back member 24 and fastened and fixed.

When the back member 24 is attached to the back side of the open / close door body 22 in this manner, the upper surface of the load support portion 29 protruding from the open / close door body 22 is the back member 24 as shown in FIGS. 7 and 10 to 11. The upper surface 61 is slightly higher than the upper surface 61, the upper surface of the load support 29 protrudes slightly upward from the upper surface of the back member 24, and the front opening portion of the engagement notch 65 formed in the back member 24 is Since the lower reinforcing plate 35 is closed by the back surface, an engagement hole 55 having an open upper surface is formed. Therefore, when the engaging portion 51 of the glass unit 23 is inserted into the both engaging holes 55 from above, the tapered surfaces (inclined surfaces) of the left and right side walls guide the engaging portion 51 to a predetermined left and right position, and Positioning is performed, and the tapered surface (inclined surface) of the rear wall guides the engaging portion 51 to a predetermined front-rear position for positioning in the front-rear direction. Can be attached in place. Further, when the engaging portion 51 is engaged in the engaging hole 55 and the glass unit 23 is sufficiently lowered, the bottom surface of the glass unit 23 is supported in a state of contacting only the upper surface of the load supporting portion 29 (FIG. 7). (C)) A slight space is formed between the bottom surface of the glass unit 23 and the upper surface portion 61 of the back surface member 24 without contacting. For this reason, all the weight of the glass unit 23 acts on the load support portion 29, and the weight of the glass unit 23 does not act on the back surface member 24.
Further, since the lower reinforcing plate 35 is sandwiched and attached, the rigidity of the load support portion 29 is increased, and the rigidity of the open / close door 8 is also increased.

Next, the structure which attaches the upper part of the glass unit 23 to the door body 22 is demonstrated.
The contact portion 70 with which the locked portion 50 is in contact with a position corresponding to the locked portion 50 of the glass unit 23 on the back surface of the open / close door body 22 (that is, on the left and right of the outer upper portion of the opening portion 21). And a rotating shaft 71 to which the locking member 25 is rotatably attached is provided in the vicinity thereof.
The abutment portion 70 may have any configuration as long as the locked portion 50 abuts and regulates its position. As shown in FIG. 12, a cylindrical projection-shaped positioning projection 69 having a taper that gradually increases in diameter from the distal end to the proximal end is provided, and a flat surface positioned outside the proximal end of the positioning projection 69 is provided. You may make it function as the contact part 70, and you may make it contact also at the front-end | tip of the positioning protrusion 69. FIG. Further, the positioning protrusion 69 is formed to have a size and a length in which a tapered hole (positioning engagement portion 52) formed in the locked portion 50 is just fitted. On the other hand, the rotation shaft 71 is a cylindrical protrusion that can be fitted into a shaft hole of the locking member 25 described later, and protrudes above the positioning protrusion 69 as shown in FIG. Yes. Then, a wall portion 72 is erected on a virtual arc centered on the rotation shaft 71 (the range in which the locking member in the present invention rotates (FIG. 15)), and the height of the tip of the wall portion 72 is increased. By making them different, the stopper portion 72a having the highest upper end portion is formed, the lowest holding step portion 72b is formed below the stopper portion 72a, and the slide portion 72c slightly higher than the holding step portion is formed therebelow.

  As shown in FIG. 13, the locking member 25 includes a cylindrical shaft-mounting portion 73 that is fitted to the above-described rotation shaft 71 and is pivotally mounted, and the tip of the shaft-mounting portion 73 is orthogonal to the axis. A pressing portion 74 that extends in the shape of an arm in a direction to press the locked portion 50, and a plate-like operation portion 75 that extends from the pressing portion 74 in the axial direction. A locking protrusion 76 that is raised in a substantially spherical shape is formed on the surface of the front side. In order to attach the locking member 25 having such a configuration to the door body 22, the shaft attaching portion 73 is fitted to the rotating shaft 71, and a screw is used as a retaining member in the hole of the shaft attaching portion 73. Tighten and attach in a rotatable state. The operation part 75 of the locking member 25 has a function of a pressing force transmission part that transmits the force when the glass unit 23 is pressed to the game board 5 side, so that the operation part 75 is attached to the opening / closing door body 22 and opened / closed. The front and rear dimensions are such that the door 8 can be brought into contact with the surface of the game board 5 or the partition member 7 or the like with the door 8 closed.

  Next, a series of operations when the glass unit 23 is attached to the back side of the door body 22 will be described. In addition, the opening / closing door body 22 is opened, and the locking member 25 is held in a state where the pressing portion 74 is rotated upward and engaged with the holding step portion 72b as shown in FIG.

  First, the engaging unit 51 at the lower end is inserted into the engaging hole 55 from above with the glass unit 23 facing the back side of the door body 22 and the upper part inclined slightly rearward. At this time, the upper surface portion 61 of the back surface member 24, specifically, the left and right upper surface portions 61 of the engagement hole 55 function as a slide portion for sliding the engagement portion 51, and therefore slides on the slide portion. The engaging portion 51 can be easily engaged (fitted) into the engaging hole 55 while the inner surface of the engaging hole 55 functions as an inclined guide surface. In addition, there is no hindrance when the load support portion 29 is fitted. If the engaging part 51 is engaged in the engaging hole 55, the glass unit 23 is sufficiently lowered. Then, the bottom surface of the glass unit 23 abuts on the upper surface of the load support portion 29 and is supported in a state slightly separated from the upper surface of the back surface member 24, and is guided by the inner surfaces of the engagement portion 51 and the engagement hole 55 and the lower portion. Positioning of the left and right and front and rear is performed. Note that the upper surface portion 61 that functions as a slide portion may be extended rearward to expand the range of the slide portion in the front-rear direction.

  Next, the upper portion of the glass unit 23 is pressed against the back surface side of the door body 22 to put the peripheral holding frame 45 inside the crime prevention rib 31, and at the same time, the door body 22 is placed in the positioning engagement portion 52 of the locked portion 50. The positioning projection 69 is fitted to position the upper portion of the glass unit 23. Then, the left and right locking members 25 are rotated by putting fingers on the operation portion 75, thereby moving the pressing portion 74 onto the locked portion 50 of the glass unit 23, and locking the front portion of the pressing portion 74. The protrusion 76 is stopped at a predetermined position where it engages with the opening of the through hole 53 of the locked portion 50 (locked state), thereby fixing the upper portion of the glass unit 23 at a predetermined position. In this locked state, the locked portion 50 of the glass unit 23 is sandwiched between the pressing portion 74 and the abutting portion 70, and is thus fixed at a predetermined position.

  When the glass unit 23 is attached to the back surface of the door body 22 in this manner, troublesome operations such as simultaneously fitting a plurality of pins into the holes are unnecessary, and when the lower part of the glass unit 23 is attached. The glass unit 23 is configured to be engaged with the engagement hole 55 from above, and when the upper portion of the glass unit 23 is attached, the glass unit 23 is simply pressed against the opening / closing door body 22 side to rotate the locking member 25. Since it was comprised so that it could do, compared with the past, attachment work is easy and reliable. Further, since the locking projection 76 protruding from the pressing portion 74 of the locking member 25 is engaged with the through-hole 53 of the locked portion 50, the locking member 25 rotates carelessly due to vibration or the like. This can be prevented, and the locked portion 50 can be locked at an accurate position by the locking member 25. Even if the locking member 25 rotates, the pressing portion 74 of the locking member 25 is locked at a position lower than the shaft attachment portion 73, and the pressing portion 74 is urged by the gravity in a downward direction. Therefore, it does not come off from the locked portion 50. The means for locking the locking member 25 is not limited to the configuration in which the locking protrusion 76 is engaged with the through hole 53 of the locked portion 50, and a known locking mechanism is employed. Can do. Moreover, since the load of the glass unit 23 is supported by the load support portion 29, the back surface member 24, which is a separate member from the open / close door body 22, is not loaded and damaged.

  If the glass unit 23 is attached to the back side of the door body 22 by the above-described operation, the door 8 is closed. Then, as shown in FIGS. 17 and 18, the operation portion 75 of the locking member 25 (specifically, the extended end portion of the operation portion 75 located on the game board 5 side) approaches or abuts the game board 5. Therefore, even if the player pushes the glass unit 23 by hand, the lower part of the glass unit 23 is transmitted from the engaging portion 51 to the inner surface of the engaging hole 55 and can be received by the back member 24. The upper part of the unit 23 can be received and received from the operation unit 75 of the locking member 25 to the game board 5.
