Description

  The present invention relates to a hinge structure in a gaming machine in which a door frame portion is pivotally attached to one side of a main body frame portion via a hinge at an upper and lower position.

Conventionally, in a pachinko gaming machine which is a kind of gaming machine, a gaming board mounting frame as a door member having a gaming board arranged and fixed on one side of the front surface of an outer frame as a main body frame portion is pivotally attached. More specifically, in the pachinko gaming machine, a holding metal fitting having a holding hole and a support metal fitting projecting from a support shaft are fixed to the upper and lower positions on one side of the front surface of the outer frame. On the other hand, on the same side of the game board mounting frame, a support fitting projecting a support shaft and a holding fitting having a holding hole are fixed to the upper and lower positions. Then, the lower support shaft is inserted into the lower holding hole and the upper support shaft is inserted into the upper holding hole in the same manner, so that the game board mounting frame can be pivoted to the outer frame. (See, for example, Patent Document 1).
Japanese Patent Laying-Open No. 2001-310047 (second page, FIGS. 1 and 5)

  However, as in the pachinko gaming machine of Patent Document 1, in the configuration in which each support shaft in the vertical position is inserted and removed in the same manner into each holding hole in the vertical position, the game board mounting frame is pivotally attached. In order to facilitate the operation by inserting the support shaft into the support shaft, the inner diameter dimension of each holding hole is set to be relatively larger than the outer diameter dimension of each support shaft. For this reason, when the game board mounting frame is pivotally attached, there is a relatively large gap between each of the upper and lower support shafts and each holding hole, and there is a backlash in the game board mounting frame because of this gap, There was a problem that it was difficult to smoothly open and close the game board mounting frame. In addition, an unnecessary gap is also generated between the outer frame and the game board mounting frame, but this is not preferable from the viewpoint of preventing fraud.

  Therefore, the present invention has been made to solve the above-mentioned problems, and the door frame can be smoothly rotated without rattling, and is also unnecessary between the main body frame and the door frame. It is an object of the present invention to provide a hinge structure in a gaming machine that is excellent in preventing fraud by preventing a gap from occurring.

  In order to achieve such an object, the hinge structure in the gaming machine according to the present invention is a hinge structure in a gaming machine in which the door frame part is pivotally mounted on one side of the main body frame part via a hinge in the vertical position. At least one of the hinges includes a first hinge member provided on the door frame portion and having a support pin, and a bearing member provided on the main body frame portion and having a fitting recess into which the support pin is fitted. An outer taper surface portion that gradually decreases in outer diameter toward the tip of the support pin, and on the other hand, gradually in the back of the fitting recess toward the back end. An inner tapered surface portion having a smaller inner diameter is formed, and the door frame portion is configured to rotate so that the outer tapered surface portion and the inner tapered surface portion are in contact with each other in an annular shape.

  Alternatively, the hinge structure in the gaming machine according to the present invention is a hinge structure in a gaming machine in which the door frame portion is pivotally attached to one side of the main body frame portion via a hinge in the vertical position, One hinge includes a first hinge member provided on the main body frame portion and having a support pin, and a second hinge member provided on the door frame portion and having a bearing member in which a fitting recess into which the support pin is fitted is provided. And an outer tapered surface portion whose outer diameter gradually decreases toward the distal end of the support pin, and the inner diameter gradually decreases toward the inner end of the insertion recess. An inner taper surface portion is formed, and the door frame portion rotates so that the outer taper surface portion and the inner taper surface portion are in contact with each other in an annular shape.

  The hinge structure in the gaming machine according to the present invention is a pair of upper and lower hinges interposed between the main body frame portion and the door frame portion, at least at the outer periphery of the distal end portion of the support pin of the one hinge. An outer taper surface portion whose outer diameter gradually decreases toward the outer periphery, and on the other hand, an inner taper surface portion whose inner diameter gradually decreases toward the inner end of the fitting recess is formed, and the outer taper surface portion and the inner taper are formed. The door frame portion is configured to rotate so that the surface portions are in contact with each other in an annular shape. Therefore, the outer taper surface portion of the support pin and the inner taper surface portion of the bearing member are always in contact with each other, and the support pin does not cause misalignment with respect to the fitting recess, thereby suppressing the backlash of the door frame portion. There is an effect that the opening and closing operation of the part can be performed smoothly. In addition, since the backlash is suppressed, there is no need to create an unnecessary gap between the main body frame portion and the door frame portion.
