Description

  The present invention relates to a game board fixing device used for detachably mounting a game board in a game board storage recess of a game machine body.

  Conventionally, for example, there is a pachinko gaming machine which is a kind of gaming machine, in which a gaming board is detachably attached from the front side of the gaming machine main body. In this pachinko gaming machine, a gaming board storage recess is formed in the front surface of the gaming machine body, and the gaming board is disposed in the gaming board storage recess with the back surface thereof facing the gaming board storage recess from the front side of the pachinko gaming machine. It is installed by pushing it in. Further, in order to fix the game board stored in the game board storage recess, a game board fixing device is fixed to the peripheral edge of the game board storage recess.

  The game board fixing device is provided with a support portion on the back side of the game board housing recess in the gaming machine main body, and a rotation shaft protrudes forward from the support portion, and rotates in a vertical plane at the front end of the rotation shaft. It consists of a structure with a fastening lever attached. On the other hand, a notch part through which the game board fixing device can pass is formed at the peripheral portion of the game board so as to correspond to the game board fixing device. Therefore, the game board is stored in the game board storage recess while the fastening lever in the game board fixing device is arranged in the vertical direction in advance, and the game board fixing device is accommodated in the notch. At this time, the fastening lever is positioned in front of the front surface of the game board, and the rear end surface thereof substantially coincides with the front surface of the game board. Then, in a state where the game board is stored in the game board storage recess, the fastening lever is rotated in the vertical plane and the rear end surface is pressed against the front surface of the game board. Thereby, a game board will be fixed (for example, refer patent document 1).

Further, the other side edge of the game board 104 is brought close to the game board mounting surface 105a of the game board storage recess 105 with the one side edge side as the center, and the other side edge is connected to each game board fixing device 1 as shown in FIG. Is lightly brought into contact with the receiving plate portion 14 of the receiving frame member 4.

  Next, the other side edge of the game board 104 is pushed backward, that is, the game board mounting surface 105a side in the above state. Accordingly, as shown in FIG. 10B, the other side edge of the game board 104 is interposed between the presser frame parts 15 and 15 and the receiving plate parts 14 and 14 of the receiving frame member 4 in each game board fixing device 1. At the same time, the receiving frame member 4 rotates against the bias of the torsion spring 26 toward the game board mounting surface 105a. When the receiving frame member 4 is rotated to a predetermined position, the long groove portions 23b of the slide shaft hole 23 are aligned with the concave grooves 11 provided on the outer peripheral surface of the fixed shaft 3, and the restraints of the operation members 5 are released. The shaft pin 25 slides in both the long holes 17 and 17 by the urging of the compression coil spring 20, and the long groove portions 23 b are fitted in the concave grooves 11 so that the front plate portion 22 moves away from the front receiving plate portion 13. The operation member 5 moves.

  Thus, the operating member 5 is fixed by fitting the long grooves 23b, 23b of the slide shaft holes 23, 23 into the both concave grooves 11, 11 of the fixed shaft 3, and the shaft pin 25 of the operating member 5 is the receiving frame member. Since the four long holes 17 and 17 are inserted, unnecessary rotation of the receiving frame member 4 is restricted. At the same time, on the game board fixing device 1 side, the spring plate 29 of the resilient member 27 abuts against the back surface 104b of the game board 104 and biases the game board 104 forward, so that the front surface of the game board 104 abuts. The game board 104 is firmly fixed without being rattled between the portions 15a and 15a. Further, as shown in FIG. 9 (b), one side edge of the game board 104 is sandwiched between the front support plate portion 121b of the clamping member 121 and the front end side 123a of the rear support plate portion 121c, and the rear support plate is supported. The front end side 123a of the plate portion 121c pushes the game board 104 forward due to its elasticity. Therefore, the game board 104 is firmly fixed between the front support plate portion 121b and the rear support plate portion 121c. In this way, as shown in FIG. 11, the gaming board 104 is smoothly mounted on the front surface of the gaming machine main body P1.

  Next, the case where the game board 104 is removed from the front side of the pachinko gaming machine P will be described. As shown in FIGS. 9 (b) and 10 (b), the game board 104 is stored in the game board storage recess 105, and the operation member 5 in each game board fixing device 1 protrudes due to the bias of the compression coil spring 20. In this case, the operation member 5 protrudes forward of the pachinko gaming machine P. In this state, as shown by an arrow (b) in FIG. 10, the front plate portion 22 of the operation member 5 is pushed backward, that is, toward the game board mounting surface 105a. As a result, the operating member 5 moves against the bias of the compression coil spring 20, and the concave grooves 11 come out of the long groove portions 23 b of the slide shaft hole 23 and enter the circular hole portion 23 a, together with the operating member 5. The receiving frame member 4 can be rotated about the fixed shaft 3. Then, the receiving frame member 4 is rotated so as to be separated from the game board mounting frame 105 a by the urging of the torsion spring 26.

  Accordingly, the other side edge of the game board 104 is pushed forward as shown in FIG. Then, the gaming board 104 whose other side edge is pushed forward in this way is pulled to the other side edge as it is, and at the same time, one side edge is pulled out from the sandwiching member 121. Thereby, the stored game board 104 can be removed from the game board storage recessed part 105. In order to store the game board 104 in the game board storage recess 105 again, the same method as described above may be used.

  Thus, in the game board fixing device 1 of the present invention, the peripheral part of the game board 104 is fitted to the receiving frame member 4 by pushing the game board 104 into the game board mounting surface 105a in the game board storage recess 105 and fitting it. When the receiving frame member 4 is fitted, the operation frame 5 is moved away from the receiving frame member 4 and the fixed shaft 3 is moved from the circular hole portion 23a to the long groove portion 23b, so that the receiving frame member 4 is unnecessary. The game board 104 is fixed by restricting the rotation operation, and when the operation member 5 is pushed toward the frame member 4 side, the fixed shaft 3 is moved from the long groove portion 23b to the circular hole portion 23a so that the frame member 4 can be rotated. Thus, the game board 104 can be removed from the game board storage recess 105. Thus, the game board 104 can be stored in the game board storage recess 105 only by pushing the side edge of the game board 104 so that the receiving frame member 4 receives the side edge part, and the game board 104 can be stored smoothly without paying extra attention. Yes. Further, simply by pressing the operating member 5 with a fingertip, the receiving frame member 4 is rotated by the biasing and pushes the game board 104 outward. Therefore, the release and removal of the game board 104 can be extremely easily performed.

  Further, the operation member 5 is disengaged from the fixed shaft 3 only by pushing the operation member 5 to the game board mounting surface 105a side with the fingertip, and the game board 104 is pushed out to the front side. Unlocking and removing 104 can be done very easily, and there is no need to touch other parts with too much hand, so there is less fear of injury.

  Further, the peripheral edge of the game board 104 is urged toward one of the receiving frame members 4 in a state where the peripheral edge of the gaming board 104 stored in the gaming board storage recess 105 is interposed in the receiving frame member 4. Is provided with a resilient member 27 that clamps and fixes the peripheral edge between the resilient frame member 4 and the resilient member 27 when the frame member 4 receives the side edge of the game board 104 stored in the game board storage recess 105. 27 spring plates 29 abut against the back surface 104b of the game board 104 and press the back surface 104b. Therefore, the side edge portion of the game board 104 is sandwiched between the spring plate 29 and the pressing portion 15a of the receiving frame member 4, and the game board 104 is firmly fixed without rattling.
