  Further, on the left side surface of the glass frame 23c of the glass window 23 as viewed from the front, a long plate-like guide rail 232a having a small frame width is erected along the outer periphery thereof. Similarly, on the right side surface of the glass frame 23c of the glass window 23, a long plate-like guide rail 232b having a small frame width is erected along the outer periphery thereof. In the guide rails 232a and 232b, upper end portions of the guide rails 232a and 232b are upper slide pieces 233a and 233b having a large frame width. The upper slide pieces 233a and 233b are provided at positions corresponding to the upper slide grooves 143a and 143b formed in the table frame 14 described above. That is, the upper slide pieces 233a and 233b are a pair of guide pieces that protrude from the oblique upper portion of the glass window 23 toward both sides and can be engaged with the upper slide grooves 143a and 143b, respectively.

  Further, in the guide rails 232a and 232b, the lower end portions of each of the guide rails 232a and 232b have a large frame width, and lower slide pieces 234a and 234b that protrude in the front view, the lower left direction and the lower right direction, respectively, are formed. The lower slide pieces 234a and 234b are provided at positions corresponding to the lower slide grooves 144a and 144b formed in the table frame 14 described above. That is, the lower slide pieces 234a and 234b are a pair of guide pieces that protrude from the diagonally lower portion of the glass window 23 toward both side surfaces and can be locked in the lower slide grooves 144a and 144b, respectively.

  Further, a glass window fixing piece 235a is formed on the glass frame 23c of the glass window 23. The glass window fixing piece 235a forms a substantially rectangular horizontal plane when viewed from the front and in the vicinity of the left side of the hooking tool 231. Similarly, a glass window fixing piece 235b is formed in the vicinity of the right side of the hooking tool 231. The glass window fixing piece 235b forms a substantially rectangular horizontal surface in plan view. The glass window fixing pieces 235a and 235b are provided at positions corresponding to the glass window fixing tools 145a and 145b formed on the above-described table frame 14. That is, the glass window fixing pieces 235a and 235b are a pair of receiving members that respectively receive the glass window fixing tools 145a and 145b for fixing the glass window 23 from above.

  Further, the glass window 23 according to the present embodiment has the following structure in order to provide the desiccant 290 for dehumidifying the inside thereof. That is, as viewed from the front, the lower left portion of the glass window 23 is provided with a desiccant support portion 500 that accommodates the desiccant 290 in its interior and covers the desiccant 290 from the back side. Note that the desiccant 290 contains granular zeolite or silica gel inside an elongated cylindrical package.

  The desiccant support portion 500 includes a thin plate-like covering portion 504 extending along the front surface of the glass plate 23b from the lower left portion of the glass frame 23c toward the inner peripheral side, and the distal end portion of the covering portion 504. And a partition portion 505 extending forward, and is formed integrally with the glass frame 23c. The partition portion 505 is installed in the gap between the glass plates 23a and 23b and is sandwiched between the glass plates 23a and 23b without any gap.

  The sealed space 300 formed by the glass frame 23c and the glass plates 23a and 23b is formed by the partition portion 505 of the desiccant support portion 500 and the viewing portion 300a located on the upper surface side of the partition portion 505 and the partition portion 505. It divides into the moisture absorption part 300b located in the lower surface side. That is, this moisture absorption part 300b is a sealed space surrounded by the desiccant support part 500 and the glass plate 23a, and the desiccant 290 is accommodated therein. Since a plurality of ventilation holes (not shown) are formed in the partition portion 505 at substantially equal intervals, air can flow between the viewing portion 300a and the moisture absorption portion 300b. Therefore, the desiccant 290 provided in the moisture absorption part 300b can absorb moisture from the visual observation part 300a through a plurality of ventilation holes (not shown).

  With this configuration, by disposing the desiccant 290 for moisture absorption inside the glass window 23, the desiccant 290 disposed in the moisture absorbing part 300 b can be visually observed from the front side of the glass window 23 through the glass plate 23 a. (Refer to FIG. 12) From the back side of the glass window 23, the desiccant 290 is hidden by the covering portion 504 and cannot be seen (see FIG. 14). When the glass window 23 is attached to the front frame 14, the desiccant support 500 is hidden by the outer periphery of the window 140 when viewed from the front (see FIG. 12) and the desiccant 290 cannot be seen. Thereby, at the time of manufacture of the glass window 23, it is easy to confirm an arrangement error or the like of the desiccant 290, and there is an effect that the aesthetic appearance is maintained after being attached to the pachinko machine 1.

  By the way, when attaching the glass window 23 to the front frame 14, it carries out in the following procedures. FIG. 15 is a rear view of the front frame 14 to which the glass window 23 is attached. As shown in FIG. 15, when attaching the glass window 23 to the front frame 14, a manufacturer or administrator of the pachinko machine 1 first holds both sides of the glass window 23 and lifts it to a predetermined height. The hanging tool 231 of the glass window 23 is hooked on the support tool 142 of the front frame 14 from behind. Further, the manufacturer or the like rotates the glass window 23 forward with the axial direction of the hooking tool 231 hooked on the support tool 142 as the center of rotation, and the front side of the glass window 23 is the back side of the front frame 14. Close to. Next, the manufacturer slightly lifts the glass window 23 supported by the upper end of the glass window 23 and fits the upper slide pieces 233a and 233b of the glass window 23 into the upper slide grooves 143a and 143b of the front frame 14 from above. At the same time, the lower slide pieces 234a and 234b of the glass window 23 are fitted into the lower slide grooves 144a and 144b of the front frame 14 from above. Finally, the glass window fixtures 145a and 145b of the front frame 14 are locked to the glass window fixtures 235a and 235b of the glass window 23, respectively. By the above procedure, the manufacturer or the like can easily and accurately attach the glass window 23 to the front frame 14.

  Here, a procedure for attaching the game board 2 to the middle frame 13 will be described. FIG. 16 is a perspective view showing a procedure for attaching the glass window 23 to the front frame 14. FIG. 17 is a partially enlarged view of the upper receiving member 30 and the upper locking piece 35. FIG. 18 is a front view of the middle frame 13 to which the game board 2 is attached. In FIG. 16, the game board 2 is represented by a virtual line for easy understanding. In FIG. 17, a state in which the game board 2 is rotated backward is indicated by a solid line, and a state in which the game board 2 is rotated forward is indicated by a virtual line.

  First, as shown in FIG. 16, the manufacturer or manager of the pachinko machine 1 grips both sides of the game board 2 and lifts them up to a predetermined height to approach the game board opening Q. Then, the upper locking piece 35 and the lower locking piece 36 of the game board 2 are respectively locked to the upper receiving tool 30 and the lower receiving tool 31 of the middle frame 13 from the upper right side. Specifically, as shown in FIG. 17, the lower end portion 35a of the upper locking piece 35 is placed on the support plate 301a of the mounting portion 30a, and the side end portion 35b of the upper locking piece 35 is brought into contact with the contact portion. It is made to fit in the support groove 304b of 30b. Similarly, the lower end portion 36a of the lower locking piece 36 is placed on a support plate (not shown) of the mounting portion 31a, and the side end portion 36b of the lower locking piece 36 is supported by the contact portion 31b. Fit into a groove (not shown).

  Here, as shown in FIG. 17, when the side end portion 35b of the upper locking piece 35 is inserted into the support groove 304b of the upper receiving member 30, the side end portion 35b comes into contact with the pair of upper and lower rear locking portions 303b. It is positioned so as to be sandwiched between the front locking portion 302b and the game board fixing frame 50. Each pair of upper and lower rear locking portions 303b abuts the side end portion 35b so as to be pivotable in the front-rear direction, and each tip portion forms a circular claw piece. Therefore, in a state where the upper locking piece 35 is locked to the upper receiving member 30 (that is, a state where the pair of upper and lower rear locking portions 303b are in contact with the side end portion 35b), the gaming board 2 has its left edge. (I.e., a contact portion between the pair of upper and lower rear locking portions 303b and the side end portion 35b) is pivotable forward until the side end portion 35b contacts the front locking portion 302b. Further, the side end portion 35b can be rotated rearward until it comes into contact with the game board fixing frame 50. In other words, the opening / closing operation of the game board 2 is limited to a range in which the side end portion 35b of the upper locking piece 35 can move in the front-rear direction in the support groove 304b of the contact portion 30b. Note that the lower locking piece 36 and the lower receiving tool 31 are the same as described above.

  Therefore, when the lower end portions 35a, 36a of the upper locking piece 35 and the lower locking piece 36 are respectively placed on the placement portions 30a, 31a of the upper receiving tool 30 and the lower receiving tool 31, the game board 2 Positioning in the vertical direction with respect to the middle frame 13 is performed. When the side end portions 35b, 36b of the upper locking piece 35 and the lower locking piece 36 are brought into contact with the contact portions 30b, 31b of the upper receiving tool 30 and the lower receiving tool 31, respectively, the game board 2 Positioning in the left-right direction with respect to the inner frame 13 is performed. That is, the game board 2 is pivotally supported in the vertical direction at the left edge thereof, so that the game board 2 does not fall even if the manufacturer or the like releases his hand from the left side surface of the game board 2, and The game board 2 can be rotated in a predetermined range in a substantially horizontal direction.

  Then, the upper lock 30 and the lower lock 38 of the game board 2 are closed by closing the game board 2 with respect to the middle frame 13 with the upper receiver 30 and the lower receiver 31 as the rotation center. The upper lock body 32 and the lower lock body 33 are engaged with each other. Specifically, when the protrusion surface 32 b of the upper lock body 32 is inserted toward the insertion / removal port 37 c of the upper lock portion 37, the fitting hole 32 c of the upper lock body 32 is locked by the main body portion 37 a of the upper lock portion 37. At the same time, the open / close piece 37d is automatically closed by the biasing force of the spring member (not shown). Therefore, when the upper lock portion 37 and the upper lock body 32 are engaged, there is no need to use the operation lever 37b to bring the opening / closing piece 37d into a released state and a closed state. Similarly, the lower lock portion 38 is engaged with the lower lock body 33. At the same time, the fitting protrusions 41a and 41b of the middle frame 13 are inserted into the fitting holes 40a and 40b of the game board 2, respectively. In this way, the game board 2 can be easily attached to the middle frame 13 by simply closing the game board 2 with the left edge supported by the upper and lower receptacles 30 and 31 with respect to the middle frame 13. Can be attached.

  Here, the upper lock portion 37, the lower lock portion 38, and the fitting holes 40a and 40b of the game board 2 correspond to the upper lock body 32, the lower lock body 33, and the fitting protrusions 41a and 41b of the middle frame 13, respectively. Each member is arranged in advance at the position. Then, when the upper locking piece 35 and the lower locking piece 36 of the game board 2 are locked to the upper receiving tool 30 and the lower receiving tool 31 of the middle frame 13, as described above, Positioning is done. Therefore, if the game board 2 is closed with respect to the middle frame 13 while maintaining the locked state, the game board 2 can be accurately attached to the game board opening Q of the middle frame 13.

  Further, in the upper lock portion 37, the insertion / removal opening 37c is formed so that the lateral width of the opening gradually increases toward the back side facing the upper lock body 32 (see FIGS. 4 and 5). Therefore, when the game board 2 is attached to the middle frame 13, the positioning of the game board 2 to the game board opening Q is not accurately performed, and the upper lock part 37 is slightly left and right with respect to the upper lock body 32. Even in the case of displacement, the upper lock body 32 can be reliably inserted into the insertion / removal port 37c from the rear (the same applies to the lower lock portion 38).

  Finally, as shown in FIG. 18, after the game board 2 is attached to the middle frame 13, the elastic tools 42 a to 42 d provided on the middle frame 13 come into contact with the back of the game board 2 and press forward. To do. Therefore, the game board 2 can be fixed in close contact with the middle frame 13, and the vibration of the game board 2 during operation of the pachinko machine 1 is prevented. Through the above procedure, the game board 2 can be easily and reliably positioned with respect to the middle frame 13 and can be appropriately fixed.

  In addition, what is necessary is just to perform the said procedure reversely, when removing the game board 2 from the middle frame 13. FIG. That is, the manufacturer holds the right side portion of the game board 2 and removes the upper lock portion 37 and the lower lock portion 38 from the upper lock body 32 and the lower lock body 33, respectively. Then, the game board 2 is rotated forward with the upper receiver 30 and the lower receiver 31 as the rotation center (the game board 2 is opened with respect to the middle frame 13), and the upper lock portion 37 of the game board 2, The lower lock portion 38 and the fitting holes 40a and 40b are removed from the middle frame 13 from the upper lock body 32, the lower lock body 33, and the fitting protrusions 41a and 41b, respectively. In order to remove the upper lock portion 37 from the upper lock body 32, the operation lever 37b is used to rotate the game board 2 rearward while holding the opening / closing piece 37d in the released state to lock the upper lock from the insertion / removal port 37c. The body 32 may be removed and then the opening / closing piece 37d may be returned to the closed state (the same applies to the lower lock portion 38 and the lower lock body 33).
