  However, in the conventional gaming machine, the trace display portion is in the vicinity of the connecting piece portion provided around the fastening portion of the fastening mechanism, and the section at the time of division of the portion enters the inside from the outer surface of the substrate case. Since the area is not an area that is widely exposed on the outer surface of the substrate case, it may be difficult to visually observe the colored portion. And, for example, if the removed fastening part is returned to the divided part and fixed using an adhesive or the like, the colored part may be covered, and the trace when the substrate case is opened may be hidden. There was room for improvement.

  The present invention solves the above-described problem, and the display of the trace display part when the substrate case is opened after the fastening mechanism is fastened is easy to see and reliably when the fastening part in the fastening mechanism is removed. An object is to provide a gaming machine capable of detecting traces.

The gaming machine according to the present invention corresponds to the bottom case portion and the lid side case portion after the substrate case including the bottom case portion and the lid side case portion houses and closes the control board. As a configuration that regulates the opening of the lid side case part to the bottom side case part by fastening the lid side fastening part and the bottom side fastening part of the fastening mechanism disposed,
After the fastening of the fastening mechanism, the board case extends from at least the lid side fastening portion and is connected to the main body side as a portion excluding the lid side fastening portion in the lid side case portion, The lid side fastening part is configured to be openable by removing it from the board case in a direction away from the bottom case part,

  In the gaming machine according to the present invention, when the circuit board case is opened after the fastening mechanism is fastened, first, the main body portion (the lid side) that extends from at least the lid side fastening portion and excludes the lid side fastening portion in the lid side case portion The connecting piece portion connected to the (main body portion) side is divided, and the lid side fastening portion is removed from the substrate case in a direction away from the bottom case portion. At that time, in the gaming machine of the present invention, the locking arm portion of the lid side fastening portion presses and moves the support arm portion connected to the design surface portion in the outward direction, and the trace display portion becomes the locking arm portion. By the movement of the supporting arm portion to be pressed, at least a part of the design surface portion is deformed, and the design of the visible portion that can be visually observed in the design surface portion is changed to be unrecoverable. This design surface part is visibly arranged on the outer surface side near the lid side fastening part in the main body part of the lid side case part, and enters the inside from the outer surface side of the substrate case as in the past. Since it is not the cross-sectional part of a connection piece part, it can be visually observed easily.

  In addition, the locking arm portion of the lid side fastening portion that moves the support arm portion of the trace display portion is disposed at a deep position near the bottom side fastening portion of the lid side fastening portion, and the connection piece portion is divided. Sometimes it is difficult to divide, and the state of protruding from the lid side fastening portion can be maintained, so that the support arm portion can be moved stably and reliably when the lid side fastening portion is moved in the removal direction.

  Furthermore, even if the fastening part is returned to the original arrangement position so as to restore the divided connecting piece part and the parting of the fastening mechanism is concealed, the visual part of the design surface part is separated from the fastening part of the fastening mechanism. Since the design has already been changed so that it cannot be restored because it is arranged on the outer surface side of the lid side body part side, the fastening part of the fastening mechanism has been accurately removed without being concealed. Traces can be displayed.

  Therefore, in the gaming machine according to the present invention, the display of the trace display part when the substrate case is opened after the fastening mechanism is fastened is easy to see and can reliably detect the trace when the fastening part in the fastening mechanism is removed. .

  In the gaming machine according to the present invention, the design surface portion of the trace display portion is preferably provided with a transparent protective cover that covers the outer surface side of the viewing region. In such a configuration, the visual part is covered with the protective cover, and the person who tries to open the substrate case illegally (unauthorized person) cannot touch the visual part after the design change. Further, it is possible to recognize the design change of the visual site of the design surface portion more stably and accurately.

  In addition, the trace display portion of the gaming machine according to the present invention has an opening width approximately approximate to the width dimension of the locking arm portion so as to allow movement of the locking arm portion around the support arm portion. It is desirable to provide a moving groove as described above, and to have an internal space that allows the movement of the support arm portion and to be covered with a housing portion surrounding the periphery.

  In such a configuration, the trace display portion is covered by a housing portion having a movement groove and an internal space that allow movement of the locking arm portion and the support arm portion, and the unauthorized opening person is This prevents the operation of disabling the locking arm and the support arm that are interlocked when the fastening part moves, making it possible to prevent traces when the fastening part in the fastening mechanism is removed more stably and accurately. can do.

  Furthermore, examples of the design change of the visual portion of the design surface portion of the trace display portion in the gaming machine according to the present invention include a change in shape, a change in pattern, or a change in color. For example, the color change can be configured such that the visual part is formed from a synthetic resin and the design (color) of the visual part is changed by whitening by plastic deformation. In this case, it is only necessary to form the visual part from a synthetic resin that can be whitened by plastic deformation and colored other than white, and the visual part of the design surface portion can be easily configured. Alternatively, as the color change, the visual site is configured by arranging a capsule containing a colorant, and the design (color) of the visual site is changed to be unrecoverable by coloring the colorant by breaking the capsule. Alternatively, it may be configured. In this case, as a colorant incorporated in the capsule, it is possible to use a colorant that is easy to visually recognize, such as a fluorescent color, and on the outer surface side of the lid-side main body portion that can ensure a wide surface when the color of the visual part changes, Since the color which is easy to visually recognize can be visually confirmed, the trace when the fastening portion of the fastening mechanism is removed can be detected more clearly.

  Furthermore, the design change of the visual part of the design surface part is to change the design of the visual part by lowering the visual part in the direction opposite to the removal direction when moving the locking arm part in the removal direction, or When the locking arm portion is moved in the removal direction, the design of the visual site can be changed by pushing up the visual site along the direction of removal.

  When the design of the visual part is changed by pulling the visual part in the direction opposite to the removal direction, for example, the support arm part includes a neck part extending from the back surface of the visual part and a removal direction of the locking arm part When the movement of the locking portion in the removing direction, the locking portion on the distal end side that is locked to the locking arm portion at the time of movement to the neck portion, and the base portion side away from the locking portion is connected to the neck portion In addition, a rotating piece portion that is rotatably arranged so as to pull down the base portion connected to the neck portion can be provided. In such a configuration, when the locking arm portion of the lid side fastening portion moves in the removal direction, the rotating piece portion of the support arm portion is pressed by the locking arm portion to remove the locking portion in the removal direction. Since it is moved, the base part connected to the neck part of the support arm part is rotated so as to pull it down in the direction opposite to the outer direction, so that the neck part is pulled down, and the viewing part is lowered.

  Further, when the visual part is pushed up in the removal direction and the design of the visual part is changed, for example, the support arm part is locked with the neck part extending from the back surface of the visual part when moving in the removal direction. In addition to having a locking portion on the distal end side that is locked to the arm portion, a coupling piece portion in which the base portion side separated from the locking portion is coupled to the neck portion can be provided. In such a configuration, when the locking arm portion of the lid side fastening portion moves in the removal direction, the coupling piece portion of the support arm portion is pressed by the locking arm portion to move the locking portion in the removal direction. Therefore, together with the base portion side, the neck portion of the support arm portion is moved in the outward direction to push up the viewing portion.

Therefore, the rotating piece 80 moves the neck 79C, which has been connected to the base 80b side, in the pull-down direction PD, and lowers the vicinity of the coupling area 74b with the neck 79 in the viewing plate 74C. Therefore, the breaking groove 74c at the periphery of the coupling area 74b is broken, and the visual plate portion 74C is plastically deformed so as to sink the coupling area 74b, and partly or entirely (in the case of the example, the whole) A trace M of the change in the shape of the hole is left. You may comprise in this way as a change of the shape in the visual observation part of the design surface part.

  Incidentally, in the fourth embodiment, when the joining area 74b is pushed up by applying the second embodiment, the surrounding breaking groove 74c may be broken to change the shape.

  Further, as a change in the pattern, if the pattern is provided on the outer surface side of the area to be whitened (near the coupling area 47b of the viewing plate portion 74) of the first and second embodiments, the movement of the support arm portions 78 and 78A is performed. At times, since the plastic deformation is performed so that the vicinity of the joint area 47b is extended, a part of the attached pattern is unrecoverably extended. Therefore, using this pattern change as a trace, the lid side fastening portion 42D may be illegally removed. It becomes possible to detect.

  In each embodiment, the fastening mechanism 41 is configured such that the lock pin 48 of the lid-side fastening portion 42 is pushed into the bottom-side fastening portion 52 and the sliding movement of the lid-side case portion 30 with respect to the bottom case portion 20 is restricted. Although illustrated, it is good also as a fastening mechanism which regulates the sliding movement with respect to the bottom side case part of a lid side case part by screwing a screw from the lid side fastening part side to the bottom side fastening part side. Furthermore, as a fastening mechanism, a structure in which a locking hook is fixed to the bottom side fastening portion side, and a lock material made of metal or the like is provided on the lid side fastening portion side so as not to be detached from the locking hook is provided. The locking material on the lid side fastening part side is inserted from the lid side fastening part side to the bottom side fastening part side, straddling the lid side fastening part side and the bottom side fastening part side, and The sliding movement of the lid-side case portion with respect to the bottom-side case portion may be restricted by being engaged with a stop hook.

  Moreover, although each embodiment illustrated the structure which divides | segments the connection piece parts 45 and 46 connected with the lid side fastening part 42D after fastening of the fastening mechanism 41, and removes the lid side fastening part 42D, You may apply this invention to the fastening mechanism of the structure which divides | segments not only the connection piece part of a lid | cover side fastening part but the connection piece part by the side of a bottom side fastening part at the time of removal of a part. Incidentally, for example, in the fastening mechanism using the lock material and the locking hook as described above, the lock material locked to the locking hook cannot be pulled out after the fastening. The connecting piece portions of both of the side fastening portions and the side fastening portions are separated, and both the lid side fastening portion and the bottom side fastening portion are removed in the removing direction, and the fastening of the fastening mechanism is released.

  Further, in each embodiment, the board cases 10, 10A, 10B, and 10C that cover the control board 7 of the pachinko gaming machines 1, 1A, 1B, and 1C have been described.
