  As shown in FIGS. 8 and 9, the welding process irradiates the welding sheet 33 interposed between the flanges 42 and 52 of the base body 40 and the cover body 50 with laser light 60L from the laser irradiation device 60, The bottom surface 46 of the flange 42 in the base body 40, the lower surface 57 of the flange 52 in the cover body 50, and the welding sheet 33 are melted, and the welding flange 34 having the welding layer 35 welded so as to integrate them is formed. .

Then, the effect of the sub control unit 12 manufactured as mentioned above is demonstrated.
The slot machine 1 according to the present embodiment includes the main control device 11 in which the control board 32 is accommodated in the accommodating portion 31 in the control board case 30 in which the flanges 42 and 52 are integrated to be integrated. Can prevent an act of exchanging the regular control board 30 and an unauthorized control board by performing an illegal act such as forcibly removing the welded state of the flanges 42 and 52.

  The control board case 30 in the present embodiment includes accommodation components 41 and 51 and flanges 42 and 52 that constitute the accommodation unit 31 in each of the base body 40 and the cover body 50, and the accommodation component units 41 and 51 that are arranged to face each other. The flanges 42 and 52 are disposed along the first side wall 41a and the side wall 51a constituting the accommodating portion 31 by joining the 51, and the overlapped flanges 42 and 52 are disposed along the first side wall 41a and the side wall 51a. In addition, since the housing portion 31 is welded over the entire circumference, the overlapped flanges 42 and 52 can be fixed over the entire circumference, so that the housing portion can be attached to the inside of the housing portion 31 from the gap between the flanges 42 and 52. It is possible to surely prevent an illegal act such that a foreign substance enters the inside of 31 and is electrically connected to the control board 32.

  In the control board case 30 in the present embodiment, the welding sheet 33 is disposed between the flanges 42 and 52, and the sheet holding portion 44 that holds the welding sheet 33 is formed on the flange 42 in the base body 40. By interposing the sheet 33 between the flanges 42 and 52, the flanges 42 and 52 can be securely fixed.

  More specifically, when the welding sheet 33 is not held at a predetermined position on the flange 42 of the base body 40, the welding sheet 33 is displaced from the predetermined position on the flanges 42, 52, thereby firmly fixing the flanges 42, 52 over the entire circumference. Although there is a possibility that the welding cannot be fixed, the sheet holding portion 44 is formed on the flange 42 of the base body 40, so that the welding sheet 33 firmly held at a predetermined position of the flange 42 over the entire circumference is provided with the flanges 42, 52. The flanges 42 and 52 can be securely fixed.

In addition, a pattern, a pattern, etc. may be added to a welding sheet, In this case, the control board case 30 which has the welding flange 34 of various patterns can be obtained, and it can have originality in an external appearance.
Furthermore, the welding sheet adds a symbol or a mark for identifying the control board case 30, so that the control board case 30 does not need to be provided with another member indicating the product number of the control board case 30, and the number of parts is reduced. be able to.

  The control board case 30 in the present embodiment is provided with the outer rib 48 on the flange 42 of the base body 40, thereby forcibly allowing foreign matter to enter the welding layer 35 from the longitudinal direction X or the lateral direction Y. Actions such as peeling off the welded state of the flanges 42 and 52 can be prevented.

  In the control board case 30 in the present embodiment, the transparent flanges 42 and 52 and the opaque welding sheet 33 are made of a synthetic resin having thermoplasticity, and the welding sheet 33 is disposed between the flanges 42 and 52. By welding the overlapped flanges 42 and 52 by laser welding to form the welding flange 34, the control board case 30 is homogeneously welded by laser welding even if the flanges 42 and 52 are transparent. And the flanges 42 and 52 can be efficiently welded, and the weld layer 35 in which the flanges 42 and 52 and the weld sheet 33 in the weld flange 34 are welded suppresses light transmission more than the flanges 42 and 52. It becomes the permeation | transmission suppression layer 35a.

  More specifically, the light energy of the laser beam 60L absorbed by the welding sheet 33 made of an opaque synthetic resin is converted into thermal energy, and the thermal energy converts the bottom surface 46 of the base body 40 and the lower surface 57 of the cover body 50; The welding sheet 33 interposed between the bottom surface 46 and the lower surface 57 is melted, and a uniform permeation suppression layer 35 a that is the welding layer 35 can be formed on the welding flange 34.

  Furthermore, the welding of the flanges 42 and 52 by laser welding is less time consuming and troublesome, without drying the adhesive or screwing in various places, as compared to fixing by adhesive or screwing. It can be carried out.

  In the control board case 30 in the present embodiment, the base body 40 and the cover body 50 assembled so that the first side wall 41a and the side wall 51a are joined are temporarily fixed with screws B, and integrated by laser welding. Laser welding can be reliably performed without the base body 40 and the cover body 50 being displaced from each other.

  In the control board case 30 in the present embodiment, the flanges 42 and 52 and the welding sheet 33 are made of the same synthetic resin, so that the welding sheet 33 can reliably weld the flanges 42 and 52.

  More specifically, if the welding sheet 33 and the flanges 42 and 52 are made of synthetic resins having different melting points, it takes time until the higher melting point of the welding sheet 33 and the flanges 42 and 52 is melted. There is a possibility that the welding sheet 33 and the flanges 42 and 52 are melted and the flanges 42 and 52 cannot be firmly welded.

  On the other hand, the welding sheet 33 and the flanges 42 and 52 in the present embodiment are made of the same synthetic resin, so that the bottom surface 46, the lower surface 57, and the welding sheet constituting the welding layer 35 are similarly melted. In this state, the flanges 42 and 52 can be firmly welded.

  In the sub-control unit 12 according to the present embodiment, in the state where the control board 32 is screwed to the cover body 50, the screwing portion 54 is slightly separated from the upper surface of the connecting portion 41 c of the base body 40 and the lower surface of the control board 32. By forming the height of the sub-control unit 12, it is possible to prevent the sub-control unit 12 from being damaged by being pinched between the connecting portion 41 c in the base body 40 and the screwing portion 54 in the cover body 50 due to an external impact. it can.

  The sub-control unit 12 in the present embodiment positions the control board 32 by the notch portion 56a of the board positioning portion 56, so that the control board 32 is not displaced with respect to the longitudinal direction X and the short direction Y. The control board case 30 is held at a predetermined position.

In correspondence between the configuration of the present invention and the above-described embodiment,
The gaming machine of the present invention corresponds to the slot machine 1 of the embodiment,
Similarly,
The control board case for gaming machines corresponds to the control board case 30,
The fixing means corresponds to the welding sheet 33,
The welding fixing part corresponds to the welding flange 34,
The fixing surface corresponds to the bottom surface 46 and the bottom surface 57,
The joint portions correspond to the joint portions 36a and 36b, the first side wall 41a, and the side wall 51a,
The fixing means holding part corresponds to the sheet holding part 44,
The fixing part and the transparent fixing part correspond to the flanges 42 and 52,
The protector corresponds to the outer rib 48,

  For example, according to the above description, the welding sheet 33 is mounted so as to be fitted into the concave sheet holding portion 44 and the arrangement position is restricted with respect to the flange 42. However, the sheet holding portion of the present invention has a cross-section. It is not limited to being formed in a concave groove shape, and may be a convex portion that is inserted and locked in a hole provided in the welding sheet 33, or a rib that is in contact with the inner peripheral surface of the frame-shaped welding sheet 33. Even in this case, the welding sheet 33 can be disposed at a predetermined position with respect to the flange 42 to be welded and fixed, so that laser welding can be reliably performed.

  Further, according to the above description, the welding flange 34 is configured by welding and integrating the flanges 42 and 52 and the welding sheet 33 interposed between the flanges 42 and 52. The flange is not limited to the use of the welding sheet 33, and at least one of the bottom surface 46 and the lower surface 57 facing the flanges 42, 52 is coated with paint, or light transmission is suppressed more than the flanges 42, 52. It is good also as a permeation | transmission suppression surface comprised with the colored transparent, semi-transparent, or opaque material.

  With the above configuration, the transmission suppressing surfaces of the flanges 42 and 52 absorb the laser light 60L and light energy is converted into heat energy, so that the welding flange 34 can be formed by welding the flanges 42 and 52 together. it can. Therefore, when at least one of the bottom surface 46 and the bottom surface 57 is a permeation suppressing surface, the welding flange 34 can be formed by welding the flanges 42 and 52 without using the welding sheet 33, and the number of parts can be increased. And can reduce costs.

  When laser welding the flanges 42 and 52 without using the welding sheet 33, the sheet holding portion 44 formed in a concave shape becomes a liquid pool portion of the flanges 42 and 52 that have been melted by laser welding, and the melted flange 42 , 52 can be prevented from flowing down to the main control board 32 inside the accommodating portion 31 and damaging the control board 32.

Further, according to the above description, the welding flange 34 is configured by welding the flanges 42 and 52 by laser welding using the welding sheet 33, but the welding flange of the present invention is formed by laser welding using the welding sheet. The flanges 42 and 52 may be fixed by an adhesive 33a that bonds the flanges 42 and 52, or the flanges 42 and 52 may be caulked by a fixing member 61 as shown in FIG. Good.

Further, the welding flange 34 may be provided with a fragile portion 49 having a reduced plate thickness.
More specifically, as shown in FIG. 12A, the welding flange 34 has a tapered portion 49a formed in a tapered shape so that the outer edge at the upper end of the outer rib 48 gradually becomes thinner toward the upper end. The base body 40 provided with (corresponding to the fragile part) and the cover body 50 may be welded to each other, or as shown in FIG. The base body 40 and the cover body 50, in which 49b (corresponding to the fragile portion) is formed over the entire circumference of the lower surface of the flange 42, may be configured.
Further, although not shown, notches 49b along the height direction of the control board case 30 may be provided on the inner periphery or the outer periphery of the outer rib 48 at a predetermined interval.
FIGS. 12A and 12B show an enlarged portion in FIG. 8 in another embodiment.

  With the above configuration, in order to perform an illegal act such as, for example, intruding the driver from the gap between the flanges 42 and 52 and peeling off the welded state of the flanges 42 and 52, the driver is inserted through the gap between the outer rib 48 and the flange 52. It is necessary to peel off the weld layer 35 which is firmly integrated while inserting and deforming the outer rib 48 outward. That is, in order to perform an illegal act, two operations of deforming the outer rib 48 outward and peeling off the welding layer 35 are necessary, and the outer rib 48 is prevented from being easily performed. By confirming the deformation, it is possible to easily find a trace of an illegal act.

  On the other hand, when the owner of the slot machine 1 checks or replaces the control board 32, the difficulty in disassembling the control board case 30 can be reduced as compared with the case where the weak part 49 is not provided.

  Further, according to the above description, the flanges 42 and 52 are configured as described above. However, the shapes of the flanges 42 and 52 are, for example, flanges 42a to 42h and 52a having shapes as shown in FIGS. You may comprise -52h.
