In the drawings described below, components having the same function are denoted by the same reference numerals, and repeated description thereof may be omitted.

(First embodiment)
FIG. 1 is a perspective view of a gaming machine 10 in which the opening device 100 according to the present embodiment can be used. In FIG. 1, only some members of the gaming machine 10 are shown for visibility. The gaming machine 10 is a pachislot machine, and includes a housing 11 and a front door 12 as an opening / closing body. A hinge is provided at the left end of the housing 11, and the front door 12 rotates in the front-rear direction around the hinge. Thereby, the front door 12 opens the front surface of the housing 11 so that the user can contact the inside of the housing 11, and the front door 12 covers the front surface of the housing 11 and enters the housing 11 by the user. It can be moved to either a closed position that limits contact. A casing device 13 having a reel is provided inside the casing 11, and the rotating device 13 is visible from the outside through a window 14 on the front door 12. Inside the housing 11, two protrusion-like locked portions 15 are provided.

  A locking mechanism 20 is provided on the back surface of the front door 12 (surface on the housing 11 side). The locking mechanism 20 includes a bracket 21 fixed to the back surface of the front door 12 and a sliding member 22 that can slide with respect to the bracket 21. The bracket 21 has a long shape and is provided such that its longitudinal direction extends along the back surface of the front door 12. The sliding member 22 is slidable along the longitudinal direction of the bracket 21. The sliding member 22 is provided with an engaged hole 24, and the sliding member 22 can be moved by applying a force to the wall surface of the sliding member 22 that forms the engaged hole 24. .

  The bracket 21 includes two locking portions 23 having a hook shape. The two locking portions 23 are provided at positions corresponding to the two locked portions 15 of the housing 11, respectively. The locking portion 23 is rotatably attached to the bracket 21 via a shaft 23a. Thereby, the latching | locking part 23 can move to either the latching position which meshes | engages with the to-be-latched part 15, and the cancellation | release position which does not mesh with the to-be-latched part 15. FIG. The number of the latching | locking part 23 and the to-be-latched part 15 is not restricted to 2, The arbitrary numbers of 1 or more may be sufficient.

  The locking portion 23 is provided so as to be interlocked with the movement of the sliding member 22 along the longitudinal direction of the bracket 21. Specifically, when the sliding member 22 moves downward (one in the longitudinal direction), the locking portion 23 moves to the locking position. On the other hand, when the sliding member 22 moves upward (the other in the longitudinal direction), the locking portion 23 moves to the release position accordingly. Since the sliding member 22 is biased downward by a spring (not shown), the locking portion 23 is in the locking position when no external force is applied to the sliding member 22. These moving directions are examples, and any configuration may be used as long as the locking portion 23 can move to the locking position or the release position by the movement of the sliding member 22.

  The bracket 21 is provided with a cylinder hole 25 for inserting a cylinder lock. The front door 12 is also provided with a cylinder hole (not shown), and the cylinder hole 25 of the bracket 21 is arranged to communicate with the front surface of the front door 12 when the bracket 21 is fixed to the back surface of the front door 12.

When the front door 12 is closed, the locking portion 23 in the locking position is engaged with the locked portion 15 of the housing 11 so that the front door 12 is locked. This locking occurs regardless of whether a cylinder lock is attached to the cylinder hole 25 or not.
When a cylinder lock is attached to the cylinder hole 25, the sliding member 22 is moved upward by inserting a key into the cylinder lock and turning it. As a result, the locking portion 23 is moved to the release position, and the front door 12 is unlocked. That is, if a cylinder lock is provided in the cylinder hole 25, the locking by the locking portion 23 and the locked portion 15 is unlocked by a key operation on the cylinder lock.
On the other hand, when the front door 12 is closed in a state where the cylinder lock is not attached to the cylinder hole 25, the front door 12 is locked without being provided with the member having the unlocking function. Can not be opened.

  On the other hand, in the present embodiment, when the front door 12 is closed in a state where the cylinder lock is not attached to the cylinder hole 25 as described above, the cylinder hole 25 is opened from the outside of the gaming machine 10 to the cylinder hole 25. The sliding member 22 can be moved upward by inserting the opening device 100 and operating the opening device 100 as described later. As a result, the locking portion 23 is moved to the release position, and the front door 12 is unlocked.

  FIG. 2 is a perspective view of the opening device 100 for the gaming machine according to the present embodiment. The opening device 100 is a cylinder which is a member having an upper surface 111, a lower surface 112, a shaft extending in a predetermined direction connecting the upper surface 111 and the lower surface 112, and a side surface 113 surrounding the shaft and extending in the predetermined direction. A cylindrical portion 110 is provided. Furthermore, the opening device 100 includes a lever 140 as an operation unit provided on the upper surface 111 and an engagement unit 150 provided on the lower surface 112. The inside of the cylinder part 110 may be hollow or filled with a predetermined material. The lever 140 and the engaging portion 150 may be provided at an arbitrary position between the upper surface 111 and the lower surface 112 of the cylindrical portion 110 instead of on the upper surface 111 and the lower surface 112. Instead of the lever 140, an arbitrary operation unit such as a button may be used.

  Of the cylindrical portion 110, at least an area where the engaging portion 150 is provided is configured so that it can be inserted from the outside of the gaming machine 10 into the inside through the cylinder hole 25. More specifically, in a region having a predetermined length from the lower surface 112 of the cylinder part 110, the diameter of the cross section perpendicular to the major axis direction of the cylinder part 110 is smaller than the diameter of the cylinder hole 25. In the present embodiment, the diameter of the cross section perpendicular to the major axis direction of the cylindrical portion 110 is the same over the entire length of the cylindrical portion 110 and is smaller than the diameter of the cylinder hole 25. The opening device 100 may have a prismatic shape instead of a cylindrical shape, and may have an arbitrary long shape that can be inserted into the cylinder hole 25 from the front surface side of the front door 12.

  As another form, in a partial region in the vicinity of the upper surface 111 of the cylindrical portion 110 (that is, a region where the engaging portion 150 is not provided), the diameter of the cross section perpendicular to the major axis direction of the cylindrical portion 110 is It is larger than the diameter of the cylinder hole 25. According to such a configuration, it is possible to prevent the opening device 100 from being accidentally dropped into the gaming machine 10 when the opening device 100 is inserted into the cylinder hole 25.

  Furthermore, the opening device 100 includes a shaft 130 that penetrates the upper surface 111 and the lower surface 112. The central axis of the shaft 130 is parallel to the long axis direction of the cylindrical portion 110, and the shaft 130 is rotatable with respect to the central axis.

  FIG. 3 is a cross-sectional view of the shaft 130 cut along a plane including the central axis thereof. A lever 140 and an engaging portion 150 are fixed to both ends of the shaft 130. Therefore, the lever 140 and the engaging part 150 rotate around the shaft 130. When the user rotates the lever 140, the engaging portion 150 is rotated, and the opening device 100 is in either a non-projecting state where the engaging portion 150 does not protrude or a protruding state where the engaging portion 150 protrudes. Take. That is, in this embodiment, the engaging part 150 that is a member that moves the sliding member 22 so as to unlock the lock is configured to be switchable between a non-projecting state and a projecting state. The lever 140 is a member for switching the state of the engaging portion 150 between a non-projecting state and a projecting state. The engaging portion 150 may transition to the protruding state by moving directly in the normal direction of the side surface 113 instead of turning. Moreover, the engaging part 150 may perform both rotation and linear motion. In addition, a drive unit such as a motor or an actuator may be used in place of the shaft 130 in order to make the engaging unit 150 transition to the non-projecting state or the projecting state.

  4A and 4B are a top view and a bottom view of the opening device 100 in a non-projecting state, respectively. As shown in FIGS. 4A and 4B, in the non-projecting state, the engaging portion 150 does not project outward from the side surface 113 when viewed from the lower surface 112 side. In other words, in the present embodiment, the non-projecting state means that the engagement portion 150 extends from a surface (hereinafter, simply referred to as an extension surface) of the cylindrical portion 110 from the side surface 113 of the cylindrical portion 110 in the major axis direction. A state that does not protrude outward.

  FIGS. 5A and 5B are a top view and a bottom view of the opening device 100 in a protruding state, respectively. As shown in FIGS. 5A and 5B, in the protruding state, the engaging portion 150 protrudes outward from the side surface 113 when viewed from the lower surface 112 side. In other words, in the present embodiment, the protruding state refers to a state in which the engaging portion 150 protrudes from the extended surface of the side surface 113 of the cylindrical portion 110 to the outside of the cylindrical portion 110.

  FIG. 6 is a diagram illustrating the operation of the opening device 100. FIG. 6A shows a region including the cylinder hole 25 of the locking mechanism 20 viewed from the back surface (surface on the housing 11 side) of the front door 12 in a state where the cylinder lock is not attached to the cylinder hole 25. FIG. The engaged hole 24 of the sliding member 22 and the cylinder hole 25 of the bracket 21 are close to each other.

  In the state of FIG. 6A, the opening device 100 in a non-projecting state is inserted into the cylinder hole 25 from the surface of the front door 12 (the surface on the opposite side of the housing 11). At this time, the lever 140 of the opening device 100 is located on the front surface side of the front door 12, and the engaging portion 150 is located on the back surface side of the front door 12. FIG. 6B is a view of a region including the cylinder hole 25 of the locking mechanism 20 as viewed from the back surface of the front door 12 in a state where the non-projecting opening device 100 is inserted into the cylinder hole 25. Thus, since the engaging part 150 does not protrude from the side surface 113 of the opening device 100 in the non-projecting state, the engaging part 150 does not become an obstacle, and the opening device 100 can be inserted from the cylinder hole 25.

  In the state of FIG. 6B, the lever 140 is rotated on the surface side of the front door 12. If it does so, the engaging part 150 will be rotated in the back surface side of the front door 12, and the open device 100 will be in a protrusion state. FIG. 6C is a view of a region including the cylinder hole 25 of the locking mechanism 20 as viewed from the back surface of the front door 12 in a state where the opening device 100 is in a protruding state. As described above, when the opening device 100 in which the engaging portion 150 is in the non-projecting state is inserted into the cylinder hole 25 and then brought into the projecting state, the engaging portion 150 is inserted into the engaged hole 24 of the sliding member 22. In this state, the sliding member 22 can be moved upward by further rotating the lever 140 or rotating the opening device 100 itself. As a result, the locking portion 23 is moved to the release position, and the front door 12 is unlocked.

  As described above, in the opening device 100 according to the present embodiment, when the user operates the lever 140 (operation unit), the engagement unit 150 does not protrude from the side surface 113 of the opening device 100. The engaging portion 150 can be switched between the protruding state in which the engaging portion 150 protrudes from the side surface 113 of the opening device 100. The opening device 100 in the non-projecting state can be inserted into the cylinder hole 25 from the outside of the gaming machine 10. The opening device 100 in the protruding state can release the locking mechanism 20 by the engaging portion 150 inside the gaming machine 10. As long as such an action can be realized, the opening device 100 can be arbitrarily changed in size, shape, operation, and the like.

  Since the engaging part 150 does not protrude from the extended surface of the side surface 113 of the opening device 100 in the non-projecting state, the opening device 100 has a cylinder hole 25 from the front side of the front door 12 even when the front door 12 is closed. Can be inserted into. Then, by operating the lever 140 with the opening device 100 inserted into the cylinder hole 25, the front door 12 can be unlocked from the front side of the front door 12 even when the front door 12 is closed. With such a configuration, when the front door 12 is accidentally locked in a state where the cylinder lock is not attached to the cylinder hole 25, the opening device 100 is removed without removing the gaming machine 10 from the fixed base (island). The front door 12 can be unlocked quickly using. Therefore, it is possible to prevent damage that may occur when the gaming machine 10 is removed from the fixed base.

  Furthermore, since the gaming machines 10 are distributed in large quantities in the market, it is desirable not to change the structure of the conventional cylinder lock and locking mechanism. For the unlocking operation by the opening device 100, a conventional cylinder hole 25 or a locking mechanism (sliding member 22, locking portion 23, etc.) can be used. Therefore, the opening device 100 can be used without changing the configuration of the conventional gaming machine 10.

(Second Embodiment)
Since the thickness of the front door of the gaming machine varies depending on the type of gaming machine, the depth of the cylinder hole varies accordingly. Since the opening device 100 according to the first embodiment has a fixed length, it may not be applicable to a gaming machine having a front door thicker than a predetermined length. On the other hand, the opening device 200 according to the present embodiment can extend and contract.

  FIG. 7 is a perspective view of the opening device 200 of the gaming machine according to the present embodiment. FIG. 7A shows the opening device 200 in a contracted state, and FIG. 7B shows the opening device 200 in an extended state. In the opening device 200, the cylinder part 110 is divided into an upper surface side cylinder part 160 on the upper surface 111 side and a lower surface side cylinder part 170 on the lower surface 112 side. The upper surface side cylindrical portion 160 includes a convex male screw portion 161. The lower surface side cylindrical portion 170 includes a concave female screw portion 171. The male screw 161 is screwed into the female screw portion 171. With such a configuration, the opening device 200 expands and contracts along the central axis by rotating the upper surface side cylindrical portion 160 and the lower surface side cylindrical portion 170 with respect to their central axes. In the upper surface side cylindrical portion 160 and the lower surface side cylindrical portion 170, the male screw portion 161 and the female screw portion 171 may be provided in reverse.

  The central axis of the shaft 130 is parallel to the long axis direction of the cylindrical portion 110, and the shaft 130 is rotatable with respect to the central axis. Unlike the first embodiment, the shaft 130 can expand and contract in accordance with the expansion and contraction of the cylindrical portion 110. FIG. 8A is a cross-sectional view of the shaft 130 cut along a plane including its central axis. FIG. 8B is a cross-sectional view of the shaft 130 taken along the line AA in FIG.

  The shaft 130 includes a cylindrical outer shaft 131 and a rod-shaped inner shaft 132 that contacts the inner wall of the outer shaft 131. The outer shaft 131 has a recess 131a extending along its central axis. The inner shaft 132 has a convex portion 132a extending along its central axis. Since the convex portion 132a is fitted in the concave portion 131a, when the outer shaft 131 is rotated with respect to the central axis of the shaft 130, the inner shaft 132 rotates with the rotation. With such a configuration, the outer shaft 131 and the inner shaft 132 can slide independently of each other along the central axis direction of the shaft 130, and the outer shaft 131 and the inner shaft 132 can simultaneously move with respect to the central axis direction. Rotate. Therefore, the rotation of the lever 140 and the rotation of the engaging portion 150 are interlocked. In the outer shaft 131 and the inner shaft 132, the concave portion 131a and the convex portion 132a may be provided in reverse. Other expansion mechanisms may be used as long as the shaft 130 can expand and contract along its central axis and the levers 140 and the engaging portions 150 provided at both ends of the shaft 130 are interlocked with each other. .

  In this embodiment, it is possible to realize the same operation as in the first embodiment, and the opening device 200 can be expanded and contracted, so that it can be applied to more types of gaming machines regardless of the depth of the cylinder hole. Applicable.
