Description

  The present invention relates to a cabinet box of a gaming machine, and more particularly to a configuration of a metal cabinet box.

  As gaming machines having cabinet boxes, there are medal gaming machines such as slot machines and poker. For example, in a slot machine, a cabinet box that has an opening on the front side and is formed in a substantially rectangular box shape, and a front door that covers the front opening of the cabinet box and that can be opened and closed via a hinge mechanism Each gaming device is arranged in a housing consisting of On the front door, there are a number of operation sections such as a medal insertion slot for inserting game medals, a start lever for starting rotation of the reel device, a stop switch for operating rotation of the reel, and a lot of game state effects. Lamps and LEDs, and game devices such as a central display board and an upper display board for controlling the operation of these displays are provided. Due to the arrangement of the operation units and the gaming devices described above, the front door becomes a considerable heavy object.

  As a result, when the front door attached to the cabinet box is opened, the entire cabinet box tends to bend and deform and the anti-hinge side of the front door tends to hang down. To cope with this, conventionally, a guide roller is provided on the front door side, and a roller receiver is provided on the cabinet box side, so that when the front door is closed, the front door is supported horizontally. .

  By the way, wood has conventionally been used as a main material for molding cabinet boxes, but it has low shielding properties against external noise used in gaming fraud, and metal assemblies that are embedded or joined to wood. There is a problem that it is difficult to separate and recover the members, and practical use of a cabinet box formed of a metal material such as a steel plate having high shielding properties and easy to dispose and recycle is being studied.

  However, if the main component material is a metal, the specific gravity is larger than that of wood, so to make it the same weight as the conventional one, the thickness of the member has to be reduced. There is a concern that the flexural deformation will increase. Regarding the installation of the front door, there is a risk that the drooping of the front door may become larger compared to the woodworking cabinet, and this must be handled by installing a large roller receiver with a wider receiving range than before. There is a problem.

  The present invention has been made in view of the above problems, and the bending deformation of the cabinet member accompanying the installation and opening / closing movement of the front door in the cabinet box made of a metal material having a thinner plate thickness than conventional wood. An object of the present invention is to provide a metal cabinet box that can prevent the occurrence of the problem and stably attach the front door and each gaming device.

The power supply box 30 and the external concentrated terminal board 34 are brought into contact with and fixed to the flat surfaces of the bracket panels 10d and 10e thus arranged. By not directly fixing to the main panel 10a via the bracket, a metal cabinet having a reduced thickness can be fixed at the same fixing position as a conventional woodworking cabinet, and the gap between the cabinet box 1 and the front door 2 during the game. It is possible to prevent illegal acts such as making a piano wire intrude through.

  In addition, four reinforcing ribs 10c having a substantially U-shaped cross section are provided at the opening edge of the front surface of the cabinet box 1 so as to connect the entire periphery. Further, the substantially U-shaped one end is further bent inwardly at a right angle to form a horizontal flange, and the U-shaped concave portion of the reinforcing rib 10c is oriented so that the horizontal flange is on the opening edge side. The main panel 10a is joined by spot welding. For example, the top plate surface 11 is disposed as shown in FIG.

  On the reinforcing rib 10c, a stud nut is welded as a female screw member 73 for attaching the gaming apparatus 3 and the assembly member disposed in the vicinity of the opening edge of the cabinet box 1. On the reinforcing rib 10c provided on the left side surface 13, a stud nut for fastening and fixing the hinge fittings 51, 51 is welded. On the reinforcing rib 10c disposed on the right side surface 14, a stud nut for fastening and fixing the locking device 52 and the rail receiver 54 is welded. Stud nuts for smoothening the sliding of the medal payout device 33 and fixing a bracket (not shown) for fixing the hopper rail 78 to the reinforcing rib 10c disposed on the lower bottom surface 15a.
