By fixing via the bracket, even a metal cabinet with a reduced thickness can be fixed at the same fixing position as a conventional woodworking cabinet.

As shown in FIGS. 4 and 11, the locking device 6 for maintaining the closed state of the front door 2 is disposed on the front side of the front door 2 and on the back side of the front door 2. A locking hook 62 that swings up and down as the unlocking port 61 rotates, and a locking hook 62 that is disposed on the right side surface 14 of the cabinet box 1 and is in the closed state of the front door 2 and the holding state of the locking hook 62. It is comprised from the receiving metal fitting 63 engaged. In addition, the receiving metal 63 is integrally formed with a fixing bracket 66 that extends vertically in the vicinity of the opening edge of the right side surface 14, and the fixing bracket 66 is fastened to the opening edge of the right side surface 14. stud nut is welded as a female screw member 73 for receiving the male screw 70 for.

  The front opening edge of the right side surface 14 is bent inward of the opening, and the bending height thereof is the same as that of the stud nut joined in the vicinity of the opening edge of the right side surface 14. For this reason, when the fixed bracket 66 is attached, the inwardly bent side abuts and supports the fixed bracket 66 and serves as the support side E. Here, for example, if the front door 2 is to be opened in a state where the unlocking port is not rotated or insufficient, that is, the tilting state of the locking hook 62 and the receiving metal 63 is not completely released in the opening direction. When a force is applied, a rotational moment acts on the cabinet box 1 through a fixed bracket 66 integral with the receiving metal fitting 63. However, since the support side E supports the moment, there is no effect on the stud nut and the periphery of the welded portion, and the plastic deformation of the right side surface 14 can be suppressed and the welded portion of the stud nut can be prevented from cracking. Thus, the rigidity of the cabinet box 1 can be increased.

As the hinge mechanism 5 for connecting the cabinet box 1 and the front door 2 so that the front door 2 can be opened and closed, a so-called slide hinge is used as shown in FIG. An example is shown, a cup 51 fixed to the front door 2, a mounting member 53 including an arm 52 rotatably connected to the cup 51 via a link, and a cabinet box by fitting the mounting member 53 1 and a fixed seat 54 fixed to the inner wall surface. In addition, as shown in FIG. 1 , the open / closed state of the front door is indicated by a two-dot chain line, and the open / close operation range is indicated by an arrow R, thereby preventing interference with adjacent gaming machines in the gaming facility or preventing game disturbance to surrounding players. Therefore, an opening angle restriction of approximately 100 degrees is provided.

  The hinge mechanism 5 is fixed to the upper and lower sides of the cabinet box 1 by screwing it to the left side surface 13 through a hole formed in the fixed seat 54. The hinge mechanism 5 is fixed at two positions on the left side surface 13, and a stud nut as a female screw member 73 for receiving a male screw 55 for fixing the hinge mechanism 5 is adjusted to the pitch of the drilled holes of the fixing seat 54, and the opening edge It is welded in the vicinity.

As shown in the figure, the front opening edge of the left side surface 13 is bent inward of the opening, and the bending height thereof is the same length as the stud nut joined in the vicinity of the opening edge of the left side surface 13. Is formed. For this reason, when the hinge mechanism 5 is attached, this inwardly bent side abuts and supports the fixed seat 54 and plays a role as the support side E. Further, the support side E is formed to extend vertically at the front opening edge of the left side surface 13.

  In the left side surface 13 and the hinge mechanism 5 configured as described above, when the front door 2 is opened to the opening angle restriction angle of the hinge mechanism 5 and further pushed beyond the range of the arrow R in the opening direction, the front door 2 is fixed. A rotational moment in a clockwise direction in plan view acts on the seat. However, the supporting edge E that contacts the front end of the fixed seat supports the moment, receives the rotational moment acting on the periphery of the stud nut and its welded portion, suppresses plastic deformation of the left side surface 13, and suppresses the welded portion of the stud nut. It is possible to prevent the occurrence of cracks and the like, and the rigidity of the cabinet box 1 can be increased.

  In addition, as shown in FIG. 2, it is good also as a structure which forms the horizontal flange F by further bend | folding the support edge E vertically further inward of the cabinet box 1. As shown in FIG. With this configuration, the attachment of the hinge mechanism 5 is stabilized, and it is possible to prevent an excessive moment load from acting around the stud nut and its welded portion in the same manner as in the above embodiment. The rigidity of can be increased.

  Next, other embodiments of the cabinet box according to the present invention will be described with reference to FIGS. 6, 7, 8, and 9. The same members as those described in the first embodiment will be described using the same reference numerals, and the basic structure of the slot machine SM given as an example of a gaming machine having a cabinet box according to the present invention in the second embodiment is as follows. As shown in FIG. 10 and FIG. 11, it is the same as that described in the first embodiment, and redundant description is omitted.

  In Example 2, four frame rods 10c formed in a U-shaped cross section at the opening edge of the front surface of the cabinet box 1 are provided so as to connect the entire periphery. The frame rod 10c is formed by press-molding a steel plate having a plate thickness (for example, plate thickness: about 1.2 to 2.3 mm) thicker than that of the main panel 10a, and has a predetermined position such as the lower corner portion of the frame rod. As a reference, a stud nut is integrally welded as a female screw member 73 by an automatic stud welding machine or the like in order to attach a gaming device or an assembly member disposed near the front opening edge. A frame rod 10c in which the position accuracy of each part is maintained in this way is provided so as to connect the entire periphery of the edge at the opening edge of the front surface of the cabinet box 1. Further, the side edge located on the front opening side of the frame rod 10c is further bent inward at right angles to form a horizontal flange F. For example, on the top surface 11, a frame collar 10c is disposed as shown in FIG. In addition, the bending raising height in the side edge formation of the frame rod 10c is formed to be the same length as the stud nut to be welded.

  Further, as a female screw member 73 for attaching a gaming device or an assembly member disposed in the vicinity of the front opening edge, for example, a stud nut is welded and joined on the frame rod 10c, and as shown in the sectional view of FIG. A stud nut for fastening and fixing the mechanism 5 is attached to the frame rod 10c disposed on the left side surface 13 in accordance with the pitch of the drill holes provided in the fixing seat 54. Similarly, as shown in the cross-sectional view of FIG. 8, the fixing bracket of the hopper rail 77 is fastened and fixed on the frame rod 10c on which the stud nut for fastening and fixing the fixing bracket 66 is disposed on the right side surface 14. Stud nuts for welding are respectively welded onto the frame rod 10c disposed on the lower bottom surface 15a. The U-shaped recesses of the frame rod 10c disposed on the top plate surface 11, the right side surface 14, and the lower bottom surface 15a are formed in a linear plane, but the left side surface 13 is as shown in FIG. In addition, around the stud nut used for fastening and fixing the hinge mechanisms 5 and 5, the U-shaped concave portion is formed to widen in the direction of the back surface 12 by the depth of the fixing seats 54 and 54 to be attached.

  When the hinge mechanism 5 is fixed to the opening edge portion of the left side surface 13 configured in this way, the side side (side having the horizontal flange F) on the front opening side of the frame rod 10c is formed to be the same length as the stud nut. Therefore, it contacts the fixed seat 54 of the hinge mechanism 5 and plays the role of the support side E of the first embodiment. Therefore, even if the front door 2 is opened to the opening angle restriction angle of the hinge mechanism 5 and further pressed in the opening direction, the support side E and the horizontal flange F are around the stud nut and its welded portion as in the first embodiment. Since the moment load acting on is received, plastic deformation of the left side surface 13 can be suppressed, cracking of the welded portion of the stud nut can be prevented, and the rigidity of the cabinet box 1 can be increased.

  Similarly, also on the right side surface 14, when the fixing bracket 66 is attached to the stud nut, the side edge on the opening edge side of the frame rod 10 c comes into contact with the fixing bracket and plays the role of the supporting edge E. For this reason, when the force is applied in the opening direction when the unlocking port 61 is not sufficiently rotated, the support side E receives the rotational moment acting on the periphery of the stud nut and its welded portion via the support fitting 63, and the right side It is possible to suppress the plastic deformation of the surface 14 and to prevent the welded portion of the stud nut from cracking.

  Further, since the support side E is formed integrally with the frame rod 10c, the rotational moment load acting on the right side surface 14 and the left side surface 13 connects the entire periphery to the opening edge via the support side E. Since it is received by the frame rod 10c attached in this way, it is possible to greatly suppress the entire cabinet box 1 from being bent and deformed. Further, in the assembling process, the positioning of the stud nut for fastening and fixing the fixing bracket 66 can be managed within the component accuracy of the frame rod 10c, and when a large number of stud nuts are directly joined to the cabinet box 1, respectively. In comparison, the positional accuracy can be increased and the number of assembly steps can be reduced.
