Description

  The present invention relates to a medal sorting device provided in a gaming machine such as a slot machine.

  Conventionally, a medal sorting device for counting authenticity of medals and counting the number of inserted medals is built in the slot machine slot. The medal sorting device has a structure in which an opening / closing plate is provided so as to be openable and closable on a substrate forming the main body of the medal sorting device. The opening / closing plate is always urged toward the substrate side by the urging force of the spring, and a medal passage is formed between the opposing surfaces of the substrate and the opening / closing plate (for example, Patent Documents 1 to 3).

  The medal passage of the medal sorting device is provided with a detection lever for detecting the presence or absence of a passing object. As a result, medals passing through the medal passage and unauthorized jigs inserted into the medal passage are detected.

  By the way, in such a medal sorting device, a large amount of medals pass through the medal passage, so that dust tends to accumulate in the medal passage. Therefore, as a maintenance of the medal sorting device, the opening / closing plate is opened and the medal passage is periodically cleaned. However, due to the structure of the medal sorting device or the circumstances of the gaming machine to which the medal sorting device is attached, the opening / closing plate may not be opened to an extent sufficient for cleaning. In that case, the opening / closing plate is removed from the substrate, and after the maintenance is completed, the opening / closing plate is attached to the substrate.

  However, after removing the opening / closing plate from the substrate and cleaning it, when attaching the opening / closing plate to the substrate again, the medal sorting device may be damaged due to incorrect installation, or the detection lever and the medal passage A gap may be formed between the two, and a problem may occur that the detection function of the unauthorized jig by the detection lever is lowered. Hereinafter, this problem will be described with reference to FIGS.

  FIG. 16 is a perspective view showing a conventional medal sorting device when the opening / closing plate is removed from the substrate. The medal sorting device 100 includes a substrate 200 and an opening / closing plate 500.

  The opening / closing plate 500 includes a coil spring 501 that connects the opening / closing plate 500 and the substrate 200, a support shaft 503 around which the coil spring 501 is wound, and a boss (projection) 502. Both ends of the coil spring 501 are fixed to a spring fixing portion (not shown) of the opening / closing plate 500, wound from both sides, and a central portion thereof is drawn out to the substrate 200 side. The coil spring 501 has a bent portion 501 a bent in an L shape in the drawn portion. When the opening / closing plate 500 is attached to the substrate 200, the bent portion 501 a is engaged with the substrate 200. To do.

  The boss 502 is a member that is located on an extension line in the axial direction of the support shaft 503 and protrudes in the axial direction.

  The substrate 200 has a pair of bearing portions 204 that receive the support shaft 503 of the opening / closing plate 500, a boss receiving portion (projection receiving portion) 202 in which a hole 203 into which the boss 502 is inserted is formed, and a surface that faces the opening / closing plate 500. And a detection lever 201 provided on the head.

  17 and 18 are views showing the medal sorting device 100 when the opening / closing plate 500 is correctly attached to the substrate 200. FIG. 17 is a perspective view when viewed from below, and FIG. 18 is a view when viewed from the right. It is a right view.

  As shown in FIGS. 17 and 18, when attaching the opening / closing plate 500 to the substrate 200, first, the boss 502 of the opening / closing plate 500 is opened / closed in the direction indicated by (1) so as to be inserted into the hole 203 of the substrate 200. The plate 500 is moved. Thereby, the relative position between the opening / closing plate 500 and the substrate 200 is determined. Next, the opening / closing plate 500 is pushed toward the substrate 200 in the direction indicated by (2) in the drawing so that the bent portion 501a of the coil spring 501 is engaged with the substrate 200.

  FIG. 19 is a bottom view of the medal sorting device 100 when the opening / closing plate 500 is correctly attached to the substrate 200. As shown in the figure, when the opening / closing plate 500 is correctly attached to the substrate 200, the coil spring 501 engages with the substrate 200 with the boss 502 inserted into the hole 203. Thus, the support shaft 503 is supported by the bearing portion 204 via the coil spring 501, and the boss 502 is supported by the boss receiving portion 202, so that the opening / closing plate 500 is stably supported by the substrate 200.

  A medal passage having a uniform width is formed between the facing surfaces of the opening / closing plate 500 and the substrate 200. At this time, the detection lever 201 provided on the substrate 200 is in contact with the opening / closing plate 500 or there is almost no gap between the opening / closing plate 500. Therefore, the unauthorized jig inserted into the medal passage can contact the detection lever 201 and detect the unauthorized jig.

  However, an operator who is not accustomed to the attachment work may forcibly attach the opening / closing plate 500 to the substrate 200 by an incorrect method. That is, without opening the boss 502 into the hole 203, the open / close plate 500 is pushed into the substrate 200 and the coil spring 501 is engaged with the substrate 200.

  FIG. 20 is a bottom view of the medal sorting device 100 when the opening / closing plate 500 is attached to the substrate 200 by such an incorrect method. In addition, (a) of FIG. 20 shows the whole lower surface, (b) is an enlarged view in the dotted line of (a). As shown in the drawing, when the opening / closing plate 500 is attached to the substrate 200 by an incorrect method, the boss 502 is not inserted into the hole 203 but contacts the outer peripheral surface of the boss receiving portion 202 in which the hole 203 is formed. Therefore, there is a possibility that the boss 502 or the boss receiving portion 202 may be damaged by a force applied to the opening / closing plate 500 during the attaching operation or a force by the coil spring 501.

  Further, since the boss 502 does not exist at the correct position, as shown in FIG. 20, the width of the medal path between the facing surfaces of the opening / closing plate 500 and the substrate 200 is widened, and the gap between the detection lever 201 and the opening / closing plate 500 is increased. A gap is created. For this reason, when an illegal jig is inserted into the gap, the illegal jig cannot be detected by the detection lever.

  The present invention has been made in view of the above problems, and its purpose is to place the opening / closing plate in a correct position without being damaged even when the opening / closing plate is attached to the substrate in a state where the protrusion is not inserted into the protrusion receiving portion. An object of the present invention is to provide a medal sorting device capable of attaching an opening / closing plate to a substrate.

  In order to solve the above-described problems, a medal sorting device of the present invention includes a substrate and an opening / closing plate provided to be openable / closable with respect to the substrate, and the opening / closing plate is detachable from the substrate. A medal sorting device, comprising a support shaft and a bearing portion that allow the opening / closing plate to rotate with respect to the substrate when the opening / closing plate is attached to the substrate, and one of the substrate and the opening / closing plate. Includes a protrusion protruding in the axial direction on an extension line in the axial direction of the support shaft, and the other plate of the substrate and the opening / closing plate has a through hole or a recess into which the protrusion enters. The protrusion receiving portion communicates the through hole or the recess and the outside along the direction of attachment of the opening / closing plate to the substrate on the one plate side of the through hole or the recess. And a communication passage through which the protrusion can pass. The width of the communication path is characterized in the smaller than the width dimension of the communicating path at the protrusion.

  According to the above configuration, even if the protrusion is not inserted into the through hole or the recess, and the opening / closing plate is pressed against the substrate, the protrusion passes through the communication path and enters the through hole or the recess. become. Therefore, damage to the protrusion or the protrusion receiving part can be prevented.

  In addition, since the width of the communication path is smaller than the dimension of the protrusion in the width direction of the communication path, it is possible to prevent the protrusion once entering the through hole or the recess from passing through the communication path and coming outside. The projection receiving portion is stably supported at the correct position.

  This provides a medal sorting device that can attach the opening / closing plate to the substrate at the correct position without being damaged even when the opening / closing plate is attached to the substrate without the protrusion being inserted into the protrusion receiving portion. can do.

  Furthermore, it is preferable that the width of the communication path gradually increases from the through hole or the recess to the outside. According to said structure, it becomes easy to enter a protrusion part into the entrance of a communicating path.

  Furthermore, the projection has a first inclined surface that approaches the other plate from the tip toward the base on the other plate side of the tip, and the projection receiving portion forms the communication path. It is preferable that an end portion of the side wall on the projection portion side has a second inclined surface in which the width of the communication path widens toward the projection portion.

  According to said structure, the side wall of the communicating path in a protrusion receiving part becomes easy to deform | transform so that a protruding part can pass a communicating path easily (it becomes easy to escape). Thereby, it becomes easy to move a projection part to the said through hole or the said recessed part.

  According to the present invention, even when the opening / closing plate is attached to the substrate without the protrusion being inserted into the protrusion receiving portion, the medal selection can attach the opening / closing plate to the substrate at the correct position without being damaged. Equipment can be provided.

<Medal selector>
Next, the configuration of the medal selector 10 will be described. The medal selector 10 is a device for selecting authenticity of medals and counting the number of inserted medals.

  3 is an external perspective view showing the front side of the medal selector 10, FIG. 4 is an external perspective view showing the back side of the medal selector 10, FIG. 5 is a front view of the medal selector 10, and FIG. 6 is a bottom view of the medal selector 10. is there. FIG. 7 is a perspective view showing a state where the opening / closing plate 50 of the medal selector 10 is removed from the substrate 20. 8 is a perspective view showing the inner surface (inner surface) of the substrate 20, and FIG. 9 is a front view showing the inner surface (inner surface) of the opening / closing plate 50 of the medal selector 10. As shown in FIG. 10 is a cross-sectional view taken along line AA in FIG. In the following description, the opposite sides of the substrate 20 and the opening / closing plate 50 are referred to as inner sides, the opposite sides are referred to as back sides, the opposite sides are referred to as inner sides, and the opposite sides are referred to as back sides. The medal selector 10 is provided with a cover on the back side, which is not shown.

  The medal selector 10 is configured such that the substrate 20 and the opening / closing plate 50 are arranged to be openable and closable, and an inlet 81 (see FIG. 4) opens upward between the opposing surfaces of the substrate 20 and the opening / closing plate 50. ) And the lower outlet 82 (see FIGS. 3 and 4) on the right side surface, a substantially L-shaped medal passage 83 (see FIGS. 3 and 7) is formed.

  The substrate 20 is U-shaped in plan view, and the standing front surface has a square shape. Further, as shown in FIG. 8, one side of the medal passage 83 is formed on the inner surface (the surface facing the opening / closing plate 50) of the square substrate 20. On the other hand, the opening / closing plate 50 has a slightly smaller plate shape that fits in a U-shaped space in a plan view of the substrate 20 and is opposed to the substrate 20. As shown in FIG. 9, as shown in FIG. Is formed.

<Composition related to determination of medal / unjust jig>
As a member for determining whether an object passing through the medal passage 83 is a medal or an improperly inserted jig (an improper jig), the substrate 20 has a detection lever 21 as shown in FIGS. The optical sensor 22 is provided on the inner surface, and the detection unit 24 is provided on the outer surface as shown in FIG.

  The detection lever 21 is a member provided in the medal passage 83 so as to be able to appear and retract. As shown in FIG. 10, the detection lever 21 is pivotally supported by a shaft 28 and is urged by a coil spring 29 so as to protrude into the medal passage 83. The detection unit 24 is disposed on the back side of the detection lever 21 and detects the movement of the detection lever 21. That is, when the detection unit 24 detects a movement in which the detection lever 21 is pushed toward the substrate 20 against the biasing force of the coil spring 29, the detection unit 24 determines that there is an object in the medal path 83 and does not detect the movement. Then, it is determined that there is no object in the medal passage 83. As described above, the detection lever 21 and the detection unit 24 function as sensors that detect the presence or absence of an object such as a medal passing through the medal path 83 or a jig (illegal jig) that is illegally inserted.

  As shown in FIG. 10, the distal end portion 21 a of the detection lever 21 enters a recess 51 formed on the wall surface of the medal passage 83 on the opening / closing plate 50 side when the opening / closing plate 50 is closed. This makes it difficult to insert the unauthorized jig into the medal passage 83 without touching the detection lever 21, and the unauthorized jig inserted into the medal passage 83 can be detected with higher accuracy.

  The optical sensor 22 is a sensor that optically detects the presence or absence of an object in the medal path 83, and includes a light emitting unit 22a and a light receiving unit 22b as shown in FIG.

  The optical sensor 22 is disposed downstream of the detection lever 21 in the medal passage 83. Therefore, the medal inserted from the entrance 81 is detected by the optical sensor 22 after contacting the detection lever 21 when passing through the medal passage 83. Since the speed of medals passing through the medal passage 83 is substantially constant, when the medals pass through the medal passage 83, the detection unit 24 determines that there is an object until the detection unit 24 determines that there is no object. During the first period, the optical sensor 22 determines that there is an object after the optical sensor 22 determines that there is an object during the second period after the detection unit 24 determines that there is an object. Each of the third periods until the determination is made is also substantially constant. Therefore, the medal selector 10 determines whether the appropriate medal is passing through the medal passage 83 based on the detection timing of the presence / absence of the object by the detection unit 24 and the optical sensor 22, or an abnormal state other than that. Can be determined. The abnormal state includes, for example, a state where an illegal jig is inserted into the medal passage 83.

<Composition related to medal selection>
Next, the main structure regarding medal selection of the medal selector 10 will be described. As a member related to medal selection, the substrate 20 includes a small-diameter medal exclusion lever 23 on the inner surface (see FIGS. 3, 4, and 8), and a solenoid 25 and a movable plate 26 on the rear surface (see FIG. 4). On the other hand, the opening / closing plate 50 is formed with an exclusion port 52 (see FIGS. 3, 5, and 9) at a position facing the small-diameter medal exclusion lever 23, and a movable guide plate 53 (see FIGS. 3, 5, and 9) and a passage forming plate. 54 (see FIGS. 5 and 9).

  The small-diameter medal exclusion lever 23 is pivotally supported so as to be able to appear and disappear in the medal passage 83 and is urged toward the inside of the medal passage 83. The width in the direction parallel to the medal path 83 and perpendicular to the medal advancing direction in the exclusion port 52 formed at a position facing the small-diameter medal exclusion lever 23 of the opening / closing plate 50 is slightly smaller than the diameter of the appropriate medal. Therefore, an appropriate medal is not excluded from the exclusion port 52 and passes through the medal passage 83 while pushing the small diameter medal exclusion lever 23 toward the substrate 20 side. On the other hand, the diameter of a medal having a smaller diameter than the appropriate medal (small medal) is smaller than the width of the exclusion port 52, so that it is pushed to the exclusion port 52 side by the small diameter medal exclusion lever 23 and excluded from the exclusion port 52.

  The movable plate 26 is a plate that receives the driving force of the solenoid 25 to move. In the movable plate 26, a movable guide link 27 is hooked on a tip end portion 26a on one end side, and the other end side is biased by a spring.

  The movable guide link 27 operates integrally with a link shaft 30 (see FIGS. 4, 8, and 9) that penetrates the substrate 20 and the opening / closing plate 50. The link shaft 30 presses the movable guide plate 53 (see FIGS. 3 and 5) on the back surface of the opening / closing plate 50 when the solenoid is turned on (excitation).

  The passage formation plate 54 is a plate that forms the passage bottom surface of the medal passage 83, and can be freely projected and lowered toward the lower portion of the passage region of the medal passage 83 through the opening 59 (see FIG. 9) below the opening / closing plate 50. Is provided. The passage forming plate 54 is connected to the movable guide plate 53 and moves together with the movable guide plate 53.

  The movable guide plate 53 has a lever shape that is long in the vertical direction, is positioned so that one end thereof overlaps the link shaft 30, and the other end is connected to the passage forming plate 54. The movable guide plate 53 is pivotally supported in the vicinity of the center of the movable guide plate 53 in parallel with the medal passage 83, and the passage forming plate 54 is urged in a direction to retract from the medal passage. Therefore, when the solenoid is OFF (de-energized), the medal selector 10 is in a state where the passage forming plate 54 is retracted from the medal passage 83 and the bottom surface of the medal passage 83 is opened for medal removal. On the other hand, when the solenoid is turned on (excitation), the link shaft 30 pushes the movable guide plate 53 to the back side of the opening / closing plate 50, and the passage forming plate 54 protrudes below the medal passage 83 to form the bottom surface of the medal passage 83. , Allowing the passage of medals.

  As described above, when the medal cannot be accepted, for example, when the return button is pressed, the inserted medal can be returned without being accepted by turning off the solenoid.

<Configuration for attaching / detaching the opening / closing plate>
The medal selector 10 of the present embodiment can be attached / detached from the substrate 20, and can be opened / closed by rotating the opening / closing plate 50 relative to the substrate 20 when the opening / closing plate 50 is attached to the substrate 20. It has the composition which becomes. As shown in FIGS. 3, 5, and 7, the opening / closing plate 50 includes a support shaft 55 that extends vertically above the side portion on the outlet 82 side, and a coil spring that is wound around the support shaft 55. 56. On the other hand, the substrate 20 is positioned on the back side of the guide surface 34 for guiding the coil spring 56 when the opening / closing plate 50 is attached to the substrate, and the spring receiving portion 31 (see FIG. 4) with which the coil spring 56 is engaged. And a pair of bearing portions 32 (see FIGS. 3 and 7) that receive the support shaft 55 of the opening / closing plate 50.

  As shown in FIGS. 3 and 5, the coil spring 56 is wound from both sides in a state where both end portions 56 a are abutted against spring fixing portions 57 provided on the back surface side of the opening / closing plate 50. Further, as shown in FIG. 7, the coil spring 56 has its central portion drawn out to the substrate 20 side. The coil spring 56 includes a first bent portion 56b that is bent toward the side portion of the opening / closing plate 50 on which the support shaft 55 is not provided, and a distal end than the first bent portion 56b. It has the 2nd bending part 56c further bent toward the board | substrate 20 in the side.

  The guide surface 34 of the substrate 20 is a surface inclined toward the side portion of the substrate 20 on the outlet 82 side. Therefore, when the opening / closing plate 50 is pressed against the substrate 20 along the attachment direction indicated by the arrow in the drawing from the state shown in FIG. 7, the portion on the tip side of the second bent portion 56 c of the coil spring 56 is the coil spring 56. And move along the guide surface 34 of the substrate 20. When the second bent portion 56 c moves to the end of the guide surface 34, the first bent portion 56 b engages with the spring receiving portion 31 of the substrate 20. Thereby, the opening / closing plate 50 is attached to the substrate 20. At this time, the coil spring 56 biases the opening / closing plate 50 toward the substrate 20. Further, by applying a force against the urging force of the coil spring 56 to the opening / closing plate 50, the opening / closing plate 50 rotates about the support shaft 55, and the side portion where the support shaft 55 is not provided is opened. Open state.

  11 and 12 are views showing the medal selector 10 when the opening / closing plate 50 is in an open state, in which FIG. 11 is a perspective view and FIG. 12 is a bottom view. As shown in the figure, by rotating the opening / closing plate 50 about the support shaft 55, the medal passage 83 is exposed, and maintenance for removing dust accumulated in the medal passage 83 can be performed.

  Further, in the present embodiment, since the opening / closing plate 50 is pivotally supported by the substrate 20, the opening / closing plate 50 has the axial direction t of the supporting shaft 55 as shown in FIGS. As shown in FIGS. 6 to 8, the substrate 20 includes a boss receiving portion 33 for receiving the boss 58 as a protrusion receiving portion. The boss 58 and the boss receiving portion 33 are provided below the outlet 82 of the medal passage 83.

  FIG. 13 is an enlarged perspective view of the boss 58. In FIG. 13, the front side is the inner side (substrate 20 side) of the opening / closing plate 50. As shown in FIG. 13, the boss 58 is a columnar protrusion protruding from the lower surface of the opening / closing plate 50. An inclined surface (first inclined surface) 58a is formed so as to be closer to the substrate 20 from the top to the top (that is, the base of the boss 58).

  FIG. 14 is an enlarged perspective view of the boss receiving portion 33. In FIG. 14, the front side is the inside of the substrate 20 (opening / closing plate 50 side). As shown in FIG. 14, the boss receiving portion 33 has a hole 33 a penetrating in the axial direction of the support shaft 55, and a hole along the attachment direction of the opening / closing plate 50 to the substrate 20 on the opening / closing plate 50 side of the hole 33 a. A communication path 33b that communicates 33a with the outside is formed.

  Here, as shown in FIG. 7, the mounting direction is a direction in which the opening / closing plate 50 and the substrate 20 face each other, and substantially coincides with a direction (width direction of the medal path) perpendicular to the surface forming the medal path 83. To do.

  The hole 33a is a long hole so that the boss 58 can be easily inserted in a state where the opening / closing plate 50 is inclined. The short diameter of the hole 33a is set to be equal to or slightly larger than the diameter of the boss 58. Further, when the opening / closing plate 50 is correctly attached to the substrate 20, the hole 33a is formed in the boss receiving portion 33 so that the boss 58 is positioned at the end of the hole 33a on the side of the communication path 33b (see FIG. 6). Yes. The wall surface of the hole 33a on the side of the communication path 33b is a curved surface having a radius of curvature corresponding to the outer peripheral surface of the cylindrical boss 58. Therefore, as shown in FIG. 12, the boss 58 is stably supported by the boss receiving portion 33 when the opening / closing plate is rotated.

  On the other hand, the width W of the communication path 33b is the dimension in the width direction of the communication path 33b in the boss 58 so that the boss 58 can pass through the communication path 33b (in this embodiment, since the boss 58 has a cylindrical shape, It is set smaller than (Yes). Further, the width W of the communication path is set to gradually increase from the hole 33a toward the outside. Therefore, even if the open / close plate 50 is pressed against the substrate 20 without inserting the boss 58 into the hole 33b and the coil spring 56 is engaged with the substrate 20, damage to the boss receiving portion 33 or the boss 58 can be prevented. This point will be described below.

  FIG. 15 is a view showing a state of the medal selector 10 when the opening / closing plate 50 is pressed against the substrate 20 without inserting the boss 58 into the hole 33a. 15 (a) and 15 (b) show a state immediately before pressing the opening / closing plate 50 against the substrate 20 without inserting the boss 58 into the hole 33a. FIGS. 15 (c) and 15 (d) show the opening / closing plate 50. The state after pressing and attaching to the substrate 20 is shown. In addition, (b) and (d) are enlarged views of dotted lines in (a) and (c), respectively.

  As shown in FIGS. 15A and 15B, the boss 58 is positioned near the entrance of the communication path 33 b of the boss receiving portion 33 immediately before the opening / closing plate 50 is pressed against the substrate 20. From this state, when the opening / closing plate 50 is pressed against the substrate 20 in the mounting direction indicated by the arrow in FIG. 15B, the distal end side of the coil spring 56 moves toward the substrate 20 along the guide surface 34 than the second bent portion 56 c. The first bent portion 56 b engages with the spring receiving portion 31. At this time, the pair of side walls 33c and 33d forming the communication path 33b in the boss receiving portion 33 receives the force from the boss 58 and escapes to the left and right so as to be separated from each other. As a result, as shown in FIGS. 15C and 15D, the boss 58 can move to the hole 33a through the communication path 33b.

  Further, since the width of the communication path 33 b is smaller than the diameter of the boss 58, the boss 58 once entering the hole 33 a can be prevented from passing outside through the communication path 33 b, and the boss 58 is stabilized by the boss receiving portion 33. Thus, it is pivotally supported at the correct position.

  Furthermore, as described above, since the width W of the communication path 33b gradually increases from the hole 33a toward the outside, the boss 58 can easily enter the entrance of the communication path 33b.

  As shown in FIG. 14, end portions on the boss 58 side of the side walls 33 c and 33 d forming the communication path 33 b (here, end portions above the side walls 33 c and 33 d) are directed toward the boss 58 (here, Inclined surfaces (second inclined surfaces) 33e and 33f are formed such that the width of the communication passage 33b increases from the bottom to the top. Therefore, when the opening / closing plate 50 is pressed against the substrate 20 in the states of FIGS. 15A and 15B, the inclined surface 58a of the boss 58 and the inclined surfaces 33e and 33f of the boss receiving portion 33 come into contact with each other. The pair of side walls 33c and 33d of the portion 33 can easily escape in the normal direction of the inclined surfaces 33e and 33f, respectively. This makes it easier for the boss 58 to pass through the communication path 33b.

  Further, as shown in FIG. 13, an inclined surface such as the inclined surface 58 a is not formed on the back side of the opening / closing plate 50 of the boss 58. Therefore, once the boss 58 is inserted into the hole 33a, the boss 58 is difficult to be removed from the hole 33a through the communication path 33b.

  Further, as shown in FIG. 5, when the opening / closing plate 50 is attached to the substrate 20, the boss 58 is set to such a height that only about half of the depth of the hole 33 a of the boss receiving portion 33 enters. . This also makes it easier for the boss 58 to pass through the communication path 33b.

  In the medal selector 10 of the present embodiment, the opening / closing plate 50 includes the support shaft 55 and the coil spring 56, and the substrate 20 includes the bearing portion 32, the guide surface 34, and the spring receiving portion 31. The support shaft and the coil spring may be provided, and the opening / closing plate 50 may include the bearing portion 32, the guide surface 34, and the spring receiving portion 31.

  In the present embodiment, the hole 33a penetrating the boss receiving portion 33 is formed. However, the boss receiving portion 33 has a recess into which the boss 58 can enter instead of the hole 33a. You may have.

  In the medal selector 10 of the present embodiment, the opening / closing plate 50 includes the boss 58 and the substrate 20 includes the boss receiving portion 33. However, the substrate 20 includes the boss 58, and the opening / closing plate 50 includes the boss receiving portion. The structure provided with 33 may be sufficient.

  Further, in the medal selector 10 of the present embodiment, the cylindrical boss 58 is provided as the protruding portion, but the shape of the protruding portion is not limited to the cylindrical shape.
