Description

  The present invention relates to a display device for a gaming machine provided in a pachinko gaming machine, a revolving gaming machine or the like.

  As a conventional technique related to a display device of a gaming machine, there is a variable display unit disclosed in Patent Document 1. This variable display unit includes an internal unit (display unit) constituting the variable display device, and a unit case in which the internal unit is accommodated. The unit case includes a back side case (back side case member) and a front side case (front side case member). The back side case and the front side case include an engagement hole provided in the back side case, and a front side. It couple | bonds by engagement with the engagement nail | claw provided in the case.

  The back side case is made of a synthetic resin and has a box shape with an open front side. Four hollow protrusions for inserting a screw member for fixing the internal unit are formed on the inner wall of the back side case so as to extend in the front-rear direction. Two of the four hollow protrusions are positioned side by side on the upper inner wall of the back side case, and the remaining two are positioned side by side on the lower inner wall of the back side case. To do. The screws inserted through the four hollow protrusions from the back side of the back side case are respectively screwed into the four female screws formed on the back surface of the female screw of the internal unit. That is, the back surface of the internal unit is screwed to the back surface of the back case.

  The internal unit includes a display and a control board for the display. The display is located on the front side of the internal unit, and the control board is located on the back side of the internal unit. The front case is formed with a recess in which the front side of the display is disposed, and an opening is formed at the bottom of the recess so as to face the display unit of the display.

  By the way, a manufacturer of a gaming machine may adopt an off-the-shelf product as a display unit to be mounted on the gaming machine. If the off-the-shelf display unit is provided with a female screw and is to be screwed to an object to be mounted using the female screw, the manufacturer of the gaming machine screws the display unit at the position of the female screw. It is necessary to manufacture a unit case that can be stopped.

  When the off-the-shelf display unit has a rectangular shape and is provided with female screws on both the left and right end surfaces or the upper and lower end surfaces, and the case member is a rectangular frame, the display unit is inserted into the frame-shaped case member Since there is a clearance between the frame-shaped case member and the display unit in the state, when the left and right end surfaces or the upper and lower end surfaces of the display unit are screwed to the left and right side portions or the upper and lower end portions of the frame-shaped case member If the screw is tightened too much, the frame-shaped case member is distorted. For example, when the left and right ends of the display unit are screwed to the left and right ends of the frame-shaped case member, the left and right ends of the frame-shaped case member bend in the direction approaching the display unit, respectively. Each of the upper and lower ends bends away from the display unit. For this reason, it becomes impossible to appropriately couple the frame-like case member to the other case member. Therefore, it is necessary to remove the distortion of the frame-shaped case member by adjusting the tightening degree of the screw. However, the adjustment operation of the screw tightening is performed, for example, by adjusting the screw tightening with the left end portion of the frame-shaped case member facing upward, and then turning the frame-shaped case member upside down. The right end of the case member is directed upward to adjust the tightening degree of the screw, and the same operation as the screwing operation is repeated, which is troublesome. Here, “up / down / left / right” is a direction in a state in which the display unit and the case member are provided in the pachinko machine.

  Also, recent display units tend to be larger, but the occupied space of the entire display device in the gaming machine is restricted by the positional relationship with other devices arranged around the display device, so the entire display device Therefore, it is necessary to devise an increase in the size of the display unit while suppressing the increase in size. One of the ideas is to reduce the frame width of the frame-like case member. However, if the frame width of the frame-shaped case member is reduced, the strength of the frame-shaped case member is sacrificed, and the frame-shaped case member is easily distorted.

  Therefore, in order to be able to easily screw the display unit to the frame-shaped case member without distorting the frame-shaped case member, the display unit and the frame-shaped case member are attached to the left and right ends. It is conceivable to screw with only one of the ends or only one of the upper and lower ends. However, in this case, the play of the display unit with respect to the unit case in the left-right direction or the up-down direction can be suppressed by the screwing. The backlash cannot be suppressed sufficiently.

  As in the variable display unit disclosed in Patent Document 1, the back side case (back side case member) is box-shaped, and the back side of the internal unit (display unit) is the back side case (back side case member). When screwed to the back side of the unit, the direction of screwing with respect to the unit case is the direction from the back side to the front side, so there is no distortion in the back side case that would interfere with the connection with the front side case. Not only can the play of the internal unit with respect to the unit case be suppressed in all directions of the left-right direction, the up-down direction, and the front-rear direction.

  The present invention has been made in consideration of the above-mentioned circumstances, and the object thereof is to provide an operator who screws the display unit to the frame-shaped case member without distorting the frame-shaped case member. It is an object of the present invention to provide a display device for a gaming machine that can be easily performed and that can suppress backlash of the display unit with respect to the unit case in all directions of the left-right direction, the up-down direction, and the front-rear direction.
