Description

  The present invention relates to a gaming machine provided with a substrate case that accommodates a substrate.

2. Description of the Related Art Conventionally, in gaming machines, it is known that a board for controlling a game is enclosed in a board case so that it cannot be easily touched from the outside in order to prevent unauthorized modification of the board.
If a board case enclosing such a board is fixed and installed so as not to move in the housing of the gaming machine, the board case and the back side of the board (surface on the housing side) cannot be seen. When the case is opened, etc., the back side of the board is modified, the board enclosed in the board case is replaced with a board that has been modified on the back side of the board, or the part that is not visible from the front side of the board case There is a problem that it is difficult to notice when a child board for performing unauthorized control is loaded or when the board case is replaced with a board case containing an illegal board. On the other hand, it is known that the board case is rotatably provided in the casing of the gaming machine so that the board case and the back side of the board can be seen (for example, Patent Document 1). By doing this, the substrate case can be rotated and the back side can be seen, so that the substrate case and the back side of the substrate can be visually confirmed in daily inspections, etc., and unauthorized modification has been made to the substrate. It can be easily confirmed whether there is any.

  Further, if the board case can be easily detached from the gaming machine, there is a problem that the possibility of fraud such as replacing the board case with a board case containing an illegal board is increased. On the other hand, Patent Document 1 includes a substrate case, a fixed base fixed to the back plate of the gaming machine housing, and a movable base that is rotatably supported by the fixed base and to which the substrate case is attached. In a state where the fixed base, the movable base, and the substrate case are integrally assembled, by restricting the removal of the movable base from the fixed base by the restriction portion provided on the substrate case, It is described that the substrate case is prevented from being removed together with the movable base.

JP 2010-284382 A

  By the way, in the conventional gaming machine described in Patent Document 1, the fixed base is formed by processing a metal plate, and the metal fixed base is attached to the back plate of the housing. In this case, if the fixed base is removed from the back plate, the fixed base, the movable base, and the board case that are integrally assembled are removed, and there is a risk that fraudulent acts on the board case and the board may be facilitated. . Therefore, it is difficult to remove the fixed base from the back plate, or it is difficult to reattach the fixed base to the part of the back plate where the fixed base has been removed. Therefore, there is a possibility that the cost may increase and the fixing base attaching operation at the time of manufacturing the gaming machine may be complicated.

  The present invention has been made in view of the above circumstances, and can make it possible to visually recognize the front and back of the board case, prevent unauthorized removal of the board case, and reduce costs and simplify assembly work. The purpose is to provide a machine.

In order to solve the above problems, the gaming machine of the present invention includes an electronic circuit board according to any of various controls,
A box-shaped housing in which a gaming member including the electronic circuit board is accommodated;
A rotation member having a rotation engagement portion rotatably engaged with the inner surface of the housing;
A transparent substrate case that is provided on the rotating member, encloses the electronic circuit board, and makes the front and back of the electronic circuit board visible by rotating integrally with the rotating member;
A fixed engagement portion integrally formed with a resin-made housing member constituting at least a part of the housing on the inner surface side of the housing and relatively rotatably engaged with the rotation engagement portion; Prepared,
A trace is left when the rotational engagement portion is removed from the fixed engagement portion.

According to such a configuration, the substrate case can be rotated together with the rotating member, and the electronic circuit board in the board case and the front and back of the board case can be visually observed to confirm whether there is any fraud. When the rotational engagement portion of the moving member is removed from the fixed engagement portion of the housing, it can be found that it has been removed by the trace. In this case, since the fixed engagement portion is integrally formed with the casing member that is at least a part of the casing, it is difficult to remove the fixing member from the casing, and the fixing member is removed from the casing member. In this case, only a part of the casing member is destroyed, traces remain, and it is difficult to return the removed fixed engagement portion to its original state.
Further, the fixed engagement portion is integrally formed with the housing member, and when the housing member is formed, the fixed engagement portion is manufactured together with the housing member. Labor saving can be achieved because there is no need to attach the housing member. Further, since it is not necessary to prepare the fixed engagement portion as a separate member from the housing member, the cost can be reduced.

  In addition, when providing in the state which attached the substrate case to the rotation member, since the visual recognition of a substrate case becomes difficult in the part which a rotation member and a substrate case overlap, it is preferable that a rotation member is also transparent. In the case where the substrate case is attached to the rotating member, it is preferable that the trace remains when the substrate case is removed from the rotating member. It is preferable that the trace remains on both the rotating member and the substrate case. Further, it is preferable that at least the trace when the rotary engagement portion is removed from the fixed engagement portion remains in the fixed engagement portion, and may remain in both the fixed engagement portion and the rotation engagement portion. When providing a member that hinders the attachment and detachment of the engaging portion and the rotational engaging portion, it is preferable that a trace also remains on the member. Further, the housing member is a housing body when the housing body excluding accessory parts of the housing is integrally formed by resin molding.

In the configuration of the present invention, the housing member is a back plate formed integrally with the body of the housing,
The rotation engaging portion of the rotating member includes a shaft;
The fixed engagement portion includes a bearing that rotatably supports the shaft around an axis,
A cover member that covers the shaft and the bearing is provided on the fixed engagement portion so that the shaft cannot be removed from the bearing in a state where the shaft is rotatably engaged with the bearing.
It is preferable that the trace remains when the cover member is removed from the fixed engagement portion.

  The housing member is a back plate formed integrally with the housing body, and it is difficult to integrally form a shaft on the inner surface of the back plate during resin molding due to the shape of the molding die and the like. By providing the moving member side and the bearing on the housing side, resin molding of the housing can be facilitated. Further, the bearing of the fixed engagement portion and the shaft of the rotation engagement portion are covered with the cover member. To remove the rotation engagement portion from the fixed engagement portion, the cover member is removed from the fixed engagement portion. The trace will remain, and fraud can be found by the trace.

  A board case enclosing an electronic circuit board can be attached to a gaming machine so that the front and back of the electronic circuit board can be checked, and a structure that is difficult to remove without being damaged can be provided at a low cost. Assembling work of the gaming machine having such a structure can be simplified.

The back plate 62 of the housing 1 is provided with a fixed engagement portion 68 formed integrally with the main body of the housing 1. The fixed engagement portion 68 has a convex portion 77 protruding in a square box shape from the inner surface of the back plate 62 of the housing 1 to the front side. The convex portion 77 has a box shape from a front surface facing the player side and parallel to the back plate 62 and four side surfaces substantially perpendicular to the front surface. The four side surfaces include an upper side surface facing upward, a lower side surface facing downward, and a left side surface and a right side surface facing left or right side respectively. These four side surfaces are square frame shapes. In the fixed engagement portion 68, the rectangular frame-shaped side surface of the convex portion 77 has a shape protruding forward from the position of the front surface of the convex portion 77. A side surface projecting forward from the front surface of the convex portion 77 is formed by a rectangular frame-shaped wall portion 78 surrounding the front surface of the convex portion 77.
The wall portion 78 has an upper side portion 79 and a lower side portion 80 along the horizontal direction, and the upper side portion 79 and the lower side portion 80 are recessed in the direction perpendicular to the back plate 62 at the left and right central portions. A recess 81 is provided. The deepest portion of the bearing recess 81 is on the back plate 62 side from the front surface parallel to the inner surface of the back plate 62 of the convex portion 77, and the bearing concave portions 81 of the upper side portion 79 and the lower side portion 80 are disposed on the front surface of the convex portion 77. A bearing groove 82 is provided so as to connect the two. The position of the deepest portion of the bearing recess 81 and the position of the deepest portion of the bearing groove 82 are substantially coincident, and the shaft 65 can be inserted across the two bearing recesses 81 and the bearing groove 82. The portions serving as the bottoms of the two bearing recesses 81 and the bearing groove 82 have a substantially semicircular shape having an inner diameter slightly larger than the outer diameter of the shaft 65.

  A bearing 67 that rotatably supports the shaft 65 is constituted by the two bearing recesses 81 and the bearing groove 82. In addition, a rectangular plate-shaped covering member 83 is disposed in the rectangular frame-shaped wall portion 78 so as to contact the front surface of the convex portion 77 with the shaft 65 inserted into the two bearing concave portions 81 and the bearing groove 82. . As a result, the bearing 67 and the shaft 65 including the two bearing recesses 81 and the bearing groove 82 are covered with the cover member 83, and the cover member 83 prevents the shaft 65 from being detached from the bearing. It has become.

  The cover member 83 is formed in a rectangular shape slightly smaller than the wall portion 78, and protrusions 84 projecting outward are formed at two locations corresponding to the bearing recess portion 81 of the wall portion 78, and the protrusion portion 84 is a bearing recess portion. 81 is inserted. The front surface of the convex portion 77 and the surface of the cover member 83 that contacts the front surface of the convex portion 77 are joined together by adhesion or welding, and the fixed engagement portion 68 or the cover member 83 must be destroyed unless the fixed engagement portion 68 is destroyed. The covering member 83 cannot be removed. Note that a trace remains in the fixed engagement portion 68 both when the fixed engagement portion 68 is broken and when the cover member 83 is broken. The fixed engagement portion 68 and the cover member 83 may be attached with a one-way screw, a caulking pin, or the like so that a trace remains when removed.

According to such a substrate unit 60, the substrate case 63 in which the electronic circuit substrate 61 is enclosed with respect to the back plate 62 of the housing 1 is not visible along the back plate 62 from the back plate 62. It can be set as the state which can be visually recognized away, for example, the state rotated 90 degree | times or more with respect to the backplate 62. FIG. The angle may be smaller than 90 degrees as long as the back surface of the substrate case 63 is visible. At this time, since the substrate case 63 is transparent, the front and back surfaces of the electronic circuit board 61 in the substrate case 63 are also visible. However, since the rotating member 64 that rotatably supports the substrate case 63 is attached to the back surface of the substrate case 63, the rotating member 64 is also transparent, so that the substrate case 63 and the electronic device The circuit board 61 is visible through the rotating member 64.
Therefore, unauthorized changes in the electronic circuit board 61 and the board case 63 can be visually confirmed. Further, as described above, the electronic circuit board 61 is taken out from the board case 63, removed from the board case 63 from the rotating member 64, and the fixing member for removing the rotation engaging part 66 from the fixed engaging part 68. In removing the cover member 83 from the joint portion 68, since a trace remains because partial destruction of the member is required, fraud can be prevented even if the substrate case 63 is rotatable as described above.

  In the present embodiment, the fixed engagement portion 68 that is rotatably engaged with the rotation engagement portion 66 of the rotation member 64 is the main body (housing member: back plate 62) of the resin casing 1. ), It is not necessary to prepare the fixed engagement portion 68 as a separate member from the housing 1, and it is not necessary to attach the fixed engagement portion 68 to the housing 1. That is, when the casing 1 is molded with a mold, the fixing engagement portion 68 is provided in the casing 1, so that cost reduction and labor saving of assembly work can be achieved. Moreover, in order to remove the fixed engagement part 68 from the housing | casing 1, it is necessary to destroy a part of housing | casing 1, and a clear trace remains.

  In addition, the joining method in which a trace remains when it is removed as described above is basically that when a joined member is removed, a part of the member or the attachment portion of the member is destroyed, and the destroyed trace is left. What remains is preferred. Further, in joining the fixed engagement portion 68 and the rotation engagement portion 66, for example, the cover member 83 is not used as a configuration in which the shaft is fixed to the rotation engagement portion 66 with the shaft passing through an annular bearing. It is good also as a structure.

  Further, the housing member in which the fixed engagement portion 68 is integrally molded is not limited to the entire main body of the housing 1. For example, when the main body of the housing 1 is assembled from a plurality of molded products, A part of the main body of the housing 1 may be a housing member formed integrally with the fixed engagement portion 68. Further, the substrate case 63 (for example, the back case 70) and the rotating member 64 may be integrally formed. In other words, the back case 70 may also serve as the rotating member 64.

  In addition, the electronic circuit board 61 is a game control board (main board) for performing the lottery for the role such as a small role or bonus role, or controlling the reel unit 22 and the hopper unit 5, but the electronic circuit board 61 is a display. It may be an effect control board (sub-board) that controls effects by sound or lighting, and may be both a game control board and an effect control board. Further, the electronic circuit board 61 may be any control board as long as it is used for some control in the gaming machine.
