The cover body can be made of an insulating synthetic resin or ceramic cover body or a conductive metal cover body.
The predetermined interval may be an interval at which the electrical component disposed on the connection location or the other surface and the cover body do not contact at least.
The cover body portion is formed so as to surround all sides of the control board so as to cover the other surface, to be in contact with the other surface and to be attachable, and to cover the other surface, or at a predetermined interval. Therefore, it is possible to form a shape that covers one surface via a substantially columnar leg portion provided for this purpose.

According to the present invention, the control board on which the electrical component is mounted can be protected.
Specifically, the cover body in a state of being mounted on the control board covers the other surface side, for example, a connection point between a leg extending from an electrical component arranged on one surface and a conductive wiring on the other surface, The electrical component arranged on the other surface can be protected.

  For this reason, the board unit can prevent an unintended external force from being applied to a connection portion between the electrical component and the conductive wiring or to the electrical component.

  Furthermore, since the connector holding part holds the connector, the board unit can prevent the connector from being damaged even when an unintended external force is applied to the connector.

  Thereby, the board | substrate unit can prevent damage to conduction | electrical_connection wiring, an electrical component, or a connector. And since it is possible to prevent an unintended external force from being applied to the control board via electrical components and connectors, the board unit can also prevent damage to the control board.

For this reason, even if the board unit is transported, the control board is prevented from being damaged and the detection of the defect is facilitated. For example, the process of assembling the control board and the cover body, and the board storage box and the board unit Can be performed at different locations.
As described above, the board unit can protect the control board on which the electrical components and the like are mounted by the cover body.

  As an aspect of the present invention, the electrical component is a first electrical component, the control board is mounted on the one surface, the first electrical component and the connector are mounted, and the second electrical component is mounted on the other surface.

For this reason, the board | substrate unit can prevent the illegal action which dust and a foreign material penetrate | invade into the inside of a board | substrate storage box, or inserts a foreign material intentionally by a flange part.

As a result, the board unit can prevent damage or short circuit due to adhesion of dust or foreign matter on the electrical components arranged on one surface, and can also prevent unauthorized actions on the control board.
Therefore, even when the connector is exposed through the opening hole of the substrate storage box, the board unit can also protect one surface of the control board on which the electrical component is mounted by the flange portion.

  Further, as an aspect of the present invention, in the position of the cover main body corresponding to the substantially columnar spacer provided in the substrate mounting portion of the substrate storage box that allows the mounting of the substrate unit facing the other surface, The spacer includes at least one protrusion erected toward the substrate mounting portion, and the spacer is inserted into the spacer from an insertion direction intersecting a facing direction in which the control substrate and the substrate mounting portion are opposed to each other.

It can be made into the shape fitted to a spacer, or a fitting lock.

  According to the present invention, when the board unit is mounted on the board mounting portion of the board storage box, the board unit can be fitted along the insertion direction so that the spacer and the protrusion can be fitted. For this reason, the board | substrate unit can determine the position with respect to a board | substrate storage box easily. At this time, the cover body can prevent damage to the control board due to contact with the spacer along the insertion direction.

  Thereby, for example, in the case of a configuration in which the control board is fastened to the spacer with the screw, the board unit allows the insertion of the screw provided in the control board and the insertion of the screw provided in the cover body. The cover insertion hole and the screw hole into which the screw provided in the spacer is screwed can be easily made substantially coincident by positioning with the spacer and the protrusion.

For this reason, even if it is a case where the position of a spacer cannot be visually recognized, the board | substrate unit can make easy mounting | wearing of the control board with respect to the board | substrate attachment part of a board | substrate storage box.
Therefore, the substrate unit can protect the other surface by the protrusion provided on the cover body and can be more easily mounted on the substrate storage box.

Further, the present invention is a control device comprising the above-described substrate unit and a substantially box-shaped substrate storage box having a substrate mounting portion that allows mounting of the substrate unit that is opposed to each other at a predetermined interval. It is characterized by.

  Further, in the left-right direction Y, the surface of the cover flat surface portion 71 facing the right side surface portion 47 is directed outward at a position corresponding to the three first insertion holes 61a as shown in FIGS. Three protruding portions 76 are formed.

  More specifically, the protrusion 76 is located near the upper end in the vertical direction and slightly forward from the approximate center in the front-rear direction X. The first insertion hole 61a is positioned near the rear end below the approximate center in the vertical direction. The hole 61a is formed at a position corresponding to the first insertion hole 61a located near the front end near the lower end in the vertical direction. That is, the protrusions 76 are arranged at different positions in the vertical direction and the front-rear direction X, respectively.

  As shown in FIGS. 8 and 10, the protrusion 76 is formed in a substantially Y-shaped cross section with an opening on the rear direction Xb side. The protrusion 76 has an opening on the rear side Xb side as an insertion port 76a that allows insertion of the spacer 47a, and is formed so as to sandwich the spacer 47a on the surface facing in the vertical direction (see FIG. 13). The projecting portion 76 is formed to protrude from the cover flat surface portion 71 with a length shorter than the axial length of the spacer 47a.

  As shown in FIGS. 7 and 10, the connector holding portion 73 is formed at a position corresponding to the connector 63 in the vicinity of the front upper end of the cover flat portion 71.

  The process of assembling the control board 60 and the cover body 70 and the process of assembling the board unit 50 and the case 40 in the power supply control device 32 configured as described above will be described in detail with reference to FIGS. .

  11 shows an explanatory diagram for explaining a first step of mounting the substrate unit 50 on the case 40, FIG. 12 shows an explanatory diagram for explaining a second step of mounting the substrate unit 50 on the case 40, and FIG. FIG. 4 is an explanatory diagram for explaining a state in which the substrate unit 50 is mounted on the case 40.

  First, the control board 60 is attached to the cover body 70. More specifically, the connector 63 of the control board 60 is inserted into the connector opening hole 73d from below. Then, the control board 60 is mounted on the cover body 70 while rotating the lower end of the control board 60 with the contact point between the connector 63 and the connector opening hole 73d as a fulcrum.

  At this time, the control board 60 is attached to the cover body 70 so that the cover side wall 72 of the cover body 70 covers the side part 61c of the printed wiring board 61 without any gap. When the control board 60 is attached to the cover body 70, the three screws 3 are inserted into the second insertion holes 61 b of the control board 60 and screwed into the screw mounting portions 75 of the cover body 70. The cover body 70 is fastened to constitute the substrate unit 50.

  Thereafter, the substrate unit 50 is attached to the case main body 43. More specifically, as shown in FIG. 11, the board unit 50 with the cover body 70 facing the right direction Yr is inserted into the case body 43 from the insertion portion 43a toward the rear direction Xb. At this time, as shown in FIGS. 10 and 12, the flange portion 73 b is positioned on the inner surface side of the upper surface portion 44, and the surrounding portion 73 a of the connector holding portion 73 is fitted into the opening hole 44 a of the case 40. insert.

  Further, when the board unit 50 is inserted in the rear direction Xb, as shown in FIG. 13, the spacer 47a is fitted to the protrusion 76 via the insertion port 76a, and the first insertion of the control board 60 is performed. The hole 61a, the screw insertion portion 74 of the cover flat portion 71, and the spacer 47a substantially coincide with each other in a side view.

  In this state, the board unit 50 is fastened to the case main body 43 by screwing the screw 2 into the spacer 47a through the first insertion hole 61a. After the case main body 43 and the board unit 50 are fastened, the power source male connector 46 c is connected to the power source female connector 66 of the control board 60.

  Thereafter, the front panel 41 is covered so as to close the insertion portion 43 a of the case main body 43, and the case main body 43 and the front panel 41 are fastened with the screws 1. Then, the switch male connector 41 c is connected to the switch female connector 65 of the control board 60.

  Further, the power supply control device 32 is configured by covering the case main body 43 with the left side panel 42 and fastening the case main body 43 and the left side panel 42 with the screws 1. The power control device 32 assembled in this way is fixed to a predetermined position of the housing body 30.

  The board unit 50, the power supply control device 32, and the slot machine 10 that realize the above-described configuration can protect the control board 60 on which the second electrical component 69 is mounted.

  Specifically, the cover body 70 mounted on the control board 60 covers the second surface 68 side, thereby extending the legs and the second surface extending from the first electric component 64 disposed on the first surface 62. It is possible to protect the soldered portion with the circuit pattern in 68 and the first electrical component 69 disposed on the second surface 68.

  For this reason, the board unit 50 can prevent an unintended external force from being applied to the soldered portion between the first electrical component 64 and the circuit pattern and the second electrical component 69.

  Furthermore, since the connector holding portion 73 holds the connector 63, the board unit 50 can prevent damage to the connector 63 even when an unintended external force is applied to the connector 63.

  Thereby, the board unit 50 can prevent damage to the circuit pattern, the second electrical component 69, or the connector 63. And since it is possible to prevent an unintended external force from being applied to the control board 60 via the second electrical component 69 and the connector 63, the board unit 50 can also prevent the control board 60 from being damaged.

For this reason, even if the board unit 50 is transported, the control board 60 is prevented from being damaged and detection of defects is facilitated. For example, the process of assembling the control board 60 and the cover body 70 and the case 40 The process of assembling the substrate unit 50 can be performed at different locations.
Thus, the board unit 50 can protect the control board 60 on which the second electrical component 69 and the like are mounted by the cover body 70.

  Further, the cover body 70 attached to the control board 60 by covering the control board 60 with the cover plane part 71 and the cover side wall part 72 causes the second electric component 69 on the second surface 68 of the control board 60. It is possible to cover the outer side and the side where the is disposed without gaps. In other words, a space without a gap surrounded by the control board 60 and the cover body 70 can be formed on the second surface 68 side of the control board 60.

Furthermore, even if the second electrical component 69 falls off, the board unit 50 can keep the second electrical component 69 in the space surrounded by the cover body 70 and the control board 60. For this reason, for example, it is possible to easily detect that an abnormal noise is generated just by lightly shaking the substrate unit 50 and the second electric component 69 is dropped.
Therefore, the board unit 50 can protect the control board 60 on which the second electric component 69 and the like are mounted by the cover body 70 and can easily detect the dropout of the second electric component 69.

  Further, since the cover body 70 is formed of a permeable synthetic resin, the substrate unit 50 can be connected to the control board 60 and the cover body 70 through the cover body 70 in a space without a gap and the control board. All the second surfaces 68 at 60 can be made observable.

  Thereby, in the unlikely event that the second electric component 69 is dropped, the board unit 50 can easily detect the dropped second electric component 69 by visual inspection through the cover body 70. For this reason, the board unit 50 can easily visually detect which part of the control board 60 is defective due to the dropping of the second electrical component 69 and the dropping.

Furthermore, since the circuit pattern and the solder portion on the second surface 68 can be observed, the board unit 50 can easily detect damage to the circuit pattern, solder cracks, and the like.
Therefore, the board unit 50 can detect not only the second electric component 69 but also the defect on the second surface 68 more easily.

  Further, since the flange portion 73b of the connector holding portion 73 is formed with an outer shape larger than the size of the opening hole 44a of the case 40, the board unit 50 can be opened when the board unit 50 is attached to the case 40. A gap between the hole 44a and the surrounding portion 73a can be blocked by the flange portion 73b. For this reason, the board unit 50 can prevent the unauthorized action of dust or foreign matter entering the inside of the case 40 or intentionally inserting the foreign matter by the flange portion 73b.

As a result, the board unit 50 can prevent the first electric component 64 from being damaged or short-circuited due to adhesion of dust or foreign matter, and can also prevent an illegal act on the control board 60.
Therefore, even when the connector 63 is exposed through the opening hole 44a of the case 40, the board unit 50 also protects one surface of the control board 60 on which the first electric component 64 is mounted by the flange portion 73b. be able to.

  Further, the cover flat surface portion 71 is provided with the insertion port 76a that allows the insertion of the spacer 47a from the rear direction Xb and is provided with the three protrusions 76 that allow the fitting, so that the cover is attached to the right side surface portion 47 of the case 40. In doing so, the substrate unit 50 can be fitted along the rear direction Xb to fit the spacer 47a and the protrusion 76.

  Therefore, the board unit 50 can easily determine the position with respect to the case 40. At this time, the cover body 70 can prevent damage to the control board 60 due to contact with the spacer 47a along the rear direction Xb.

  Further, since the spacer 47a and the protrusion 76 are fitted to each other, the positioning of the board unit 50 and the right side face part 47 is facilitated. Therefore, the board unit 50 includes the first insertion hole 61a of the control board 60, the cover body, and the cover body. The screw insertion portion 74 of the 70 and the spacer 47a can be made to substantially coincide with each other easily.

For this reason, the board unit 50 can easily attach the control board 60 to the right side surface portion 47 of the case 40 even when the position of the spacer 47a is not visible.
Therefore, the board unit 50 can protect the second surface 68 by the protrusion 76 provided on the cover body 70 and can be more easily attached to the case 40.

  Further, by attaching the board unit 50 to the case 40, the board board 50 that protects the control board 60 on which the second electric component 69 is mounted and can easily detect the drop-off of the second electric part 69 is installed before assembly. In addition, it is possible to configure the power supply control device 32 that facilitates the detection of defects in the control board 60.

  Further, the power supply control device 32 is arranged inside the housing body 30, so that the power supply control device 32 that makes it easy to detect a defect of the control board 60 constitutes the slot machine 10 that can perform a stable game. be able to.
