  Further, the roller 38 at the lower end of the stay 30 is placed on the bent portion 90c of the carriage 90b.

  By doing so, the constant load spring 76 always has a constant load regardless of the amount of expansion / contraction, and thus always works to lift the carriage 90b and the stay 30 upward with a constant force.

  Accordingly, in any of the positions from the fully open position to the fully closed position, a uniform spring force always acts on the stay 30 and acts in the direction of opening the cover 14, and when opening the cover 14 from the fully closed state to the fully open state, It can be done smoothly with a small force.

  In addition, by appropriately setting the spring force of the constant load spring 76, the cover 14 can be kept open even at an intermediate position between full open and full close, and the operability can be further improved.

  Moreover, since the load of the constant load spring 76 acts also when the cover 14 is closed, it is possible to prevent the cover 14 from being suddenly closed due to the weight of the cover 14.

  Further, when the cover 14 is opened and the stay 30 is lifted, a moment in the clockwise direction acts on the carriage 90b due to the winding of the constant load spring 76, whereby the inner roller 38a and the outer roller 38b of the carriage 90b are moved. Rolling while acting so as to sandwich the guide rail 40, the cover 14 can be opened and closed by the smooth movement of the carriage 90b.

  Further, in such an opening / closing device 16, when the cover 14 is removed for some reason, the stay 30 can be engaged and fixed by the main body side mechanism portion 28, and when the engagement of the stay 30 is released. Since the stay 30 not receiving the load of the cover 14 may jump out suddenly by the urging force of the constant load spring, the stay 30 is attached to the attachment portion 92 of the stay 30 to the cover 14 as shown in FIGS. Engagement prevention means 94 for preventing engagement by the main body side mechanism portion 28 is provided.

  This engagement preventing means 94 is attached to the stay 30 so that the hinge shaft 36 located at the upper end of the stay 30 can slide in the left-right direction, and the upper mounting plate 96 sandwiching the edge of the cover 14 on the hinge shaft 36 and The lower mounting plate 98 is supported.

  The upper mounting plate 96 is in a fixed position with respect to the stay 30, and two mounting holes 102 for inserting the screw portions of the handle 100 are formed.

  A hinge shaft 36 can project from one end of the upper mounting plate 96 (the right end in FIGS. 12 and 14).

  The lower mounting plate 98 has a mounting hole 108 formed at a position corresponding to the mounting hole 102 of the upper mounting plate 96 and is integrated with the hinge shaft 36 in the axial direction via the positioning ring 104. It is slidable together with the hinge shaft 36.

  A spring 106 is mounted on the hinge shaft 36 between the stay 30 and the lower mounting plate 98, and the hinge shaft 36 and the lower mounting plate 98 are biased to the right in FIGS. ing.

  In this state, first, the upper mounting plate 96 is applied to the upper surface side of the cover 14 and the lower mounting plate 98 is applied to the lower surface side, and the lower mounting plate 98 and the hinge shaft 36 are resisted against the biasing force of the spring 106 as shown in FIG. 14 to the left, the positions of the mounting holes 102 and 108 of the upper mounting plate 96 and the lower mounting plate 98 coincide.

  In this state, if the screw part of the handle 100 is inserted into the attachment holes 102 and 108 and the nut 110 is tightened (see FIG. 13), the attachment can be performed with the hinge shaft 36 stored in the attachment part 92.

  When removing the attachment portion 92 from the cover 14, the nut 110 is removed, and the handle 100 is attached to the attachment hole while pressing the lower attachment plate 98 and the hinge shaft 36 to the left in FIGS. 12 and 14 against the biasing force of the spring 106. It can be pulled out from 102,108.

  In this case, when the handle 100 is pulled out, the lower mounting plate 98 and the hinge shaft 36 are pressed rightward in FIGS. 12 and 14 by the biasing force of the spring 106, and the hinge shaft 36 protrudes from the right end of the mounting portion 92. It will be.

  Therefore, even if the stay 30 is pushed into the game machine main body 12, the protruding end of the hinge shaft 36 comes into contact with the upper surface of the game machine main body 12 and cannot enter, so that the stay 30 cannot be locked. Become.

  Next, the opening / closing operation state of the opening / closing device 16 will be described.

  First, as shown in FIG. 2, when the cover 14 is fully closed with respect to the game machine body 12, the pair of opening / closing mechanisms 24 are engaged with the latch holding member 42 with respect to the closing holding member 32. The closed state is maintained.

  Next, as shown in FIG. 3, with the left opening / closing mechanism 24 in the locked state in the drawing, the unlocking mechanism 46 of the right opening / closing mechanism 24 in the drawing is operated to bring the rotating plate 72 into contact with the contact plate 74. When the latch member 42 is disengaged from the closing holding member 32, the carriage 90b is lifted upward with a constant force by the urging force of the constant load spring 76.

  At this time, in the opening / closing mechanism 24 on the left side in the drawing, the hinge shaft 36 is the rotation center of the cover 14.

  Next, as shown in FIG. 4, when the right cover 14 in the drawing is lifted upward, the stay 30 is lifted as the cover 14 is lifted.

  In this case, the stay 30 is pushed up by the carriage 90b that is biased upward with a constant load by the constant load spring 76, so that the lifting operation of the cover 14 can be performed smoothly with a small force.

  In addition, when the constant load spring 76 is taken up when the stay 30 is lifted, a moment in the clockwise direction acts on the carriage 90b, and the inner roller 38a and the outer roller 38b roll while acting so as to sandwich the guide rail. Thus, a smoother opening operation can be obtained.

  Furthermore, the stay 30 has a roller 38 provided at the lower end thereof guided outward along the guide rail 40 and the upper end thereof moves inward as the cover 14 is opened. The lower portion of 30 is urged inward by its own weight.

  When the cover 14 is opened to the fully open state, the roller 38 comes out from the upper end of the guide rail 40, and the open maintaining member 34 provided at the lower portion of the stay 30 moves to the open support member 44 side by the dead weight of the stay 30. When the hand is released from the cover 14, the opening maintaining member 34 is placed and supported on the opening supporting member 44 to maintain the fully opened state.

  Further, at the time of opening, even if the cover 14 is opened upward from the fully open state, the opening maintaining member 34 abuts on the upper limit stopper 64, so that movement beyond the design specification is not permitted. It is also possible to prevent the slipping out from the portion 28 side.

  Further, when the opening maintaining member 34 moves onto the opening support member 44, the return piece 62 moves the stay 30 outward, so that the opening maintaining member 34 does not interfere with the opening support member 44 and is reliable. Transition operation will be performed.

  Then, in this state, the work inside the game machine body 12 may be replenished from the open part, or the work of unevenly presenting the preferentially present prize may be performed, the cover 14 may be moved to another place, It is not necessary for a person to have it, and one worker can easily perform the work.

  Further, since the opening / closing mechanism 24 is located between the operation panels 22, the cover 14 is in a state in which one side of the cover 14 is opened, and the cover 14 straddles the two tables 20. This can be done and the work efficiency is also improved.

  Further, even if an operator accidentally hits the cover 14 and moves it in the direction of lifting the cover 14 during the work, the stay 30 is prevented from being pulled out by the upper limit stopper 64, and the opening prevention member 34 is prevented by the drop-off prevention unit 60. Can be prevented from falling off from above the open support member 44 and closing the cover 14.

  Next, after the work is completed, the cover 14 on the opening side is slightly lifted, the lower end portion of the stay 30 is moved outward, and the opening maintaining member 34 is moved outward from the opening support member 44. If lowered, the roller 38 of the stay 30 is surely placed on the carriage 90b in the guide rail 40, and can be easily closed if the cover 14 is closed as it is.

  Also in this case, since a constant load is applied by the constant load spring 76 via the carriage 90b, the cover 14 is not suddenly closed by the weight of the cover 14, and a smooth closing operation can be performed. it can.

  Next, when the cover 14 is further pushed down, the closing holding member 32 descends along the engaging guide groove 66, abuts on the engaging guide portion 58 of the latch member 42, and engages while rotating the latch member 42 inward. The latch member 42 is engaged with the closing holding member 32 at that time, and is locked to maintain the fully closed state (see FIG. 2).

  Next, when the unlocking mechanism 24 on the left side in the figure is unlocked by the same operation as described above and the cover 14 is fully opened, the work can be easily and efficiently performed on the opposite side of the game machine body 12.

  Further, in the state where the attachment portion 92 is attached to the cover 14, as described above, the hinge shaft 36 is housed in the attachment portion 92, and the stay 30 is inserted into the game machine body 12. It can be locked in the state.

  On the other hand, in a state where the attachment portion 92 is removed from the cover 14 and the handle 100 is pulled out, the hinge shaft 36 protrudes outward from the attachment portion 92 by the biasing force of the spring 106, so that the stay 30 is brought into the game machine body 12. Even if it is completely pushed in, the protruding portion of the hinge shaft 36 comes into contact with the upper surface of the game machine body 12 and cannot be pushed in.

  Accordingly, it is possible to prevent the stay 30 from being locked with the cover 14 removed and the unlocked stay 30 from protruding upward due to the urging force of the constant load spring 76.

  The present invention is not limited to the above-described embodiment, and can be modified into various forms within the scope of the gist of the present invention.

  For example, in the above embodiment, a game machine using an opening / closing device has been described. However, the opening / closing device is not limited to a game machine, and may be various types as long as it has a lid that opens and closes in the vertical direction. It is possible to apply.
