When the flange 54 is slid in the unlocking direction (upward in the embodiment) against the bias of the springs 56 and 67, the lower end of the loose insertion long hole 65 becomes the headed pin 66 as shown in FIG. The mechanism plate projecting piece 59 is moved up by contact. Then, the engagement between the mechanism plate protrusion 59 and the engagement hole 34 is released simultaneously in the vertical direction, and the mechanism plate 12 can be opened in this state.

  Next, mounting of the game board 10 will be described. In order to mount the game board 10 on the game board holding frame 11, the left side of the game board 10 faces the installation area 22 from the front side of the game board holding frame 11 with the transparent plate door frame 4 opened. It is inserted into the holding portion 75 between the piece 23 and the elastic piece 48. At this time, as shown in FIG. 6, the tip of the elastic piece 48 does not protrude from the bent piece 47 and is formed in an inclined surface within the bent piece 47 so that it is elastic at the side end of the game board 10. The game board 10 can be guided without being pushed into the back of the holding part 75 and can be smoothly inserted between the support piece 23 and the elastic piece 48, and one end of the game board 10 is held by the elastic piece 48. 75 can be surely pressed and fixed. When the right side of the game board 10 is pushed into the installation area 22, the notched end of the engaging part 28 comes into contact with the tapered guide part 70 of the game board protrusion 61. The operating rod 55 moves downward together with the game board protrusion 61 against the bias of the spring 57. When the rear surface of the game board 10 comes into contact with the support piece 23, the operating rod 55 is restored by the bias of the spring 57, and the locking portion 61 a of the game board protrusion 61 is engaged with the end portion of the engagement portion 28. Thus, the game board 10 is easily mounted on the game board holding frame 11. At this time, the operating rod 55 moves down beyond the unlocking range of the door frame protrusion 60, but the transparent plate door frame 4 has already been opened, so there is no influence. Then, when the transparent plate door frame 4 is closed, the press member 21 provided on the transparent plate door frame 4 elastically presses the surface of the game board 10, so that the game board 10 is firmly attached to the game board holding frame 11. Retained.

  Next, in order to remove the game board 10 from the game board holding frame 11, first, the cylinder lock 52 is rotated by the key K and the transparent board door frame 4 is unlocked. The free end of the frame 4 is opened. The unlocking operation of the cylinder lock 52 causes the game board protrusion 61 to move down at the same time. However, the locking portion 61a of the game board protrusion 61 depends on the amount of the locking portion 60a of the door frame protrusion 60. Since the engagement amount of the game board is set to be larger, the engagement between the game board protrusion 61 and the engaging portion 28 of the game board 10 is not released, and it is unnecessarily detached from the game board holding frame 11. There is nothing. When the operating piece 71 is operated and the operating rod 55 is moved downward in the opened state of the transparent plate door frame 4, the game board protruding piece 61 is interlocked to release the engagement with the engaging portion 28. In this state, the game board 10 can be removed from the game board holding frame 11 by pulling out the right end of the game board 10 toward the front and pulling out the left end of the game board 10 from the holding portion 75 between the support piece 23 and the elastic piece 48. . In this embodiment, the amount of rotation of the cylinder lock 52 is restricted by the stopper 72 so that the operating rod 55 moves within the unlocking range of the door frame projection piece 60. However, the rotation restriction by the stopper 72 is eliminated. It is also possible to unlock the game board 10 by further rotating the cylinder lock 52 after unlocking the transparent plate door frame 4. When the transparent lock door frame 4 and the game board 10 can be released by rotating the cylinder lock 52 stepwise in the same direction, an unlocking confirmation protrusion is provided in place of the stopper 72 and transparent. It is preferable that the cam plate 53 comes into contact with the protrusion when the plate door frame 4 is unlocked to temporarily become a resistance so that the game board 10 is not unlocked at once. In addition, a regulation piece that protrudes from the back surface of the transparent plate door frame 4 so as to be positioned below the game board projection 61 may be provided to regulate the downward movement of the game board projection 61. When the door frame 4 is in a closed state, the restricting piece faces below the game board protrusion 61 and prevents the operating rod 55 from sliding beyond the unlocking range of the transparent plate door frame 4. It is also possible to release the restriction by opening and to allow the unlocking operation of the game board protrusion 61 by the cylinder lock 52. You may make it add the function of the pressing member 21 which presses the game board 10 mentioned above to this control piece.

  As described above, since the locking means for holding the game board 10 on the game board holding frame 11 is provided in the locking device 5 such as the transparent plate door frame 4, the number of parts such as a fixture for fixing the game board 10 can be increased. The cost can be reduced. Further, by forming the tip of the game board protrusion 61 in the tapered guide portion 70, the game board 10 can be easily mounted simply by pushing it into the game board installation area 22, and the work of attaching the game board 10 Improves. Furthermore, since the game board protrusion 61 can be provided at the end of the game board holding frame 11, it is possible to increase the game area 10a without taking up space, and in recent years to improve the interest of games. Therefore, it is possible to cope with an increase in the size of a display device desired.

  In the embodiment, one end of the game board 10 is sandwiched and held by the holding portion 75 between the support piece 23 and the elastic piece 48. However, it is not limited to the fixing means, and one side is rotated. The other side may be supported by the projecting piece 61 for game board as shown in the above embodiment. At this time, although the hinge device of the mechanism plate 12 has been described, a guide portion is provided for positioning so that the axis of the shaft pin is positioned in the shaft hole when the game board 10 is rotatably mounted so that the mounting operation is efficient. It is better to make it better. In addition, one side may be attached by a conventional game board fixing tool, and at that time, by locking one side of the game board 10 with the game board projection piece 61, the game board projection piece 61 is provided. It will serve as a temporary stop, and the game board 10 can be easily attached. Further, in preparation for the case where the holding member 21 or the game board protrusion 61 is damaged, an attachment portion may be formed on the game board holding frame 11 in advance so that the game board fixing tool can be attached.

  16 and 17, the locking portion 61 a of the game board protrusion 61 is formed as a plate-like locking surface, and the front surface of the game board 10 is pressed against the locking surface and contacted with the game board 10. The Example which provided the light friction means which reduces frictional resistance is shown. Specifically, a support roller 76 is provided as a light friction means, and the bearing piece 78 of the support roller 76 is erected by opening substantially the center of the locking surface. The shaft 61 is rotatably supported in the sliding direction 61. The support roller 76 may be resinous or metal. Thus, by providing the support roller 76 on the locking surface 61a, the game board 10 can be reliably pressed and locked to the installation area 22, and also when the transparent plate door frame 4 is opened with a key, The contact resistance with the game board 10 can be reduced. The contact position of the support roller 76 when the game board protrusion 61 and the game board 10 are engaged, that is, the distance from the end of the receiving portion 28 to the contact position of the support roller 76 is determined by the transparent plate door frame 4. The unlocking operation range is set so that the support roller 76 is positioned so as not to be detached from the engaging portion 28 even when the transparent plate door frame 4 is unlocked. For this reason, it can carry out smoothly, without applying a load to the unlocking operation of the transparent plate door frame 4. Further, even if a bearing is provided on the locking surface 61a as a light friction means instead of the support roller 76, the contact resistance with the game board 10 can be reduced, and the same effect as the support roller 76 can be obtained. it can.

  In the embodiment, the game board protruding piece 61 and the door frame protruding piece 60 are integrally provided on the operating rod 55, and the locking directions of the locking portions 60a and 61a are the same direction. The locking direction of the protruding piece 60 may be opposite to the locking direction of the gaming board protruding piece 61, and the vertical direction is supported by pivotally supporting the intermediate portion of the door frame protruding piece 60 with respect to the substrate 51. By pivotally supporting one end of the door frame protruding piece 60 on the operating rod 55, the locking direction of the locking portions 60a and 61a is reversed by sliding the operating rod 55 in the same direction. can do. That is, when the operating rod 55 is moved, the door frame protrusion 60 rotates upward to release the engagement with the locking hole 20 of the transparent plate door frame 4, and further, the operating rod 55 is moved downward. The engagement between the game board 10 and the game board protrusion 61 can be released. Further, by providing the door frame protrusion 60 so as to be rotatable, the amount of rotation of the door frame protrusion 60 can be adjusted by changing the pivotal support position, and the operation rod 55 can be moved with a small amount of movement. Many of the locking portions 60a can be moved. Therefore, the locking portion 61a of the game board protruding piece 61 may be slightly larger than the amount of release movement of the locking portion 60a of the door frame protruding piece 60, and the gaming board protruding piece 61 can be made compact. .

  In addition, the length of the locking portion 60a of the door frame projection piece 60 and the length of the locking portion 61a of the game board projection piece 61 are made different, so that the transparent plate door frame 4 is more than the game board 10. The engagement is released first, but the locking portions 60a and 61a of the door frame protrusion 60 and the game board protrusion 61 are formed to have the same length, and the game board protrusion 61 is locked. The length of the engaging portion 28 of the game board 10 that can be locked by the portion 61a is longer than the length of the locking hole 20 of the transparent plate door frame 4 that can be locked by the locking portion 60a of the door frame protrusion 60. Even so, the respective locking amounts can be made different, and the transparent plate door frame 4 can be unlocked first, and then the engagement of the game board 10 can be released. At this time, the door frame protrusion 60 itself may be regulated so that the locking portion 60a of the door frame protrusion 60 is not locked more than a predetermined amount. It is preferable to provide a restricting means such as a step-like restricting portion for restricting the amount of engagement so as not to be locked more than a predetermined amount.
