[Technical field]

[0001] The present invention relates to a fastening device for fastening a gaming machine to components constituting the gaming machine. [Background technology]

[0002] A gaming machine (e.g., a pachinko gaming machine) is composed of multiple components, such as a gaming board, decorative components that decorate the gaming machine, and input components such as buttons and levers. Here, the gaming board in particular may be detachable from the inner frame of the gaming machine for maintenance inspection or replacement with a new machine.

[0003] As an attachment / detachment mechanism for such a game board, a mounting tool for attaching and detaching the game board to and from the inner frame has been disclosed (see Patent Document 1). This is said to enable the game board to be easily attached and detached to the inner frame.

[0004] However, with the above-mentioned mounting tool, when mounting the game board with the mounting tool, it is necessary to insert the game board into the clamping portion provided on the inner frame. Therefore, when mounting the game board, it is necessary to push the game board into the inner frame while keeping the game board inserted in the clamping portion, which causes a problem that the burden on the mounting work of the game board is large.

Note that the arrangement of the fastening device 1 in Fig. 1 is a state rotated 90 degrees forward from the state in Fig. 2 with respect to the decorative member 101, the game board 103, the liquid crystal member 104, the handle 106, and the accessory 107, and is in the state in Fig. 2 with respect to the input device 105. In the rest of this specification, the up and down directions in Figure 2 will be referred to as the up and down directions, the depth and front directions in Figure 2 will be referred to as the side directions (horizontal directions), the left and right directions in Figure 2 will be referred to as the front and rear directions, and the rightward direction will be referred to as the front direction. The fastening device 1 is a device for fastening each of the components of the gaming machine to the inner frame 102 of the gaming machine 100. In this embodiment, an example will be described in which the components of the gaming machine are gimmicks 107. The fastening device 1 is composed of a fastening mechanism body 200 fixed to the inner frame 102, and an insert body 300 fixed to the accessory 107. The fastening device 1 has two states: a fastened state in which the fastening mechanism body 200 and the insert body 300 are combined (integrated) and fixed so as not to come out, and a released state in which the insert body 300 comes out of the fastening mechanism body 200 and is separated.

[0015] <Fastening mechanism body> 3a is a plan view of the fastening mechanism body 200 in the released state, FIG. 3b is a plan view of the fastening mechanism body 200 with the top plate removed, and FIG. 4 is a cross-sectional view of the fastening mechanism body 200 and insert 300 in the released state taken along the line AA in FIG. 3a. The fastening mechanism body 200 has an external appearance of a substantially rectangular parallelepiped shape. The size of the fastening mechanism body 200 may be such that the lower limit of the length in the front-rear direction (longitudinal direction) is 25 mm or more, preferably 30 mm or more, and more preferably 35 mm or more. The size of the fastening mechanism body 200 may be such that the upper limit of the length in the front-rear direction (longitudinal direction) is 300 mm or less, preferably 200 mm or less, and more preferably 100 mm or less. The size of the fastening mechanism body 200 may be such that the lower limit of the length in the lateral direction (short side direction) is 10 mm or more, preferably 15 mm or more, and more preferably 20 mm or more. The size of the fastening mechanism body 200 may be such that the upper limit of the length in the front-rear direction (short side direction) is 150 mm or less, preferably 100 mm or less, and more preferably 50 mm or less. Furthermore, the size of the fastening mechanism body 200 may be such that the lower limit of the height (length in the vertical direction) is 5 mm or more, preferably 10 mm or more, and more preferably 15 mm or more. The size of the fastening mechanism body 200 may be such that the upper limit of the height (length in the vertical direction) is 60 mm or less, preferably 50 mm or less, and more preferably 40 mm or less. By being in this size range, the fastening device 1 has sufficient load-bearing performance, and can be disposed without the fastening device 1 protruding from the outer periphery of the gaming machine 100 when fixed to the gaming machine 100. The fastening mechanism body 200 of this embodiment has a length in the front-rear direction (longitudinal direction) of 44 mm, a length in the horizontal direction (short direction) of 31 mm, and a height (length in the vertical direction) of 21 mm. The fastening mechanism main body 200 comprises a rectangular parallelepiped base 201, a top plate 202 stacked and fixed on the upper surface of the base 201, a fastening / release unit 20 having a switching member 203 that slides in the longitudinal direction (front and back directions) parallel to the upper surface of the base 201, and a slide fastening / release unit 30 that switches the switching member 203 between a slidingly movable state and a non-sliding state using a locking member 205.

[0016] FIG. 5 is a plan view of the base 201. The base 201 has a columnar or conical shape with a flat upper surface, and in this embodiment, is formed into a rectangle. The base 201 in this embodiment has a shape of a substantially rectangular parallelepiped with each vertex chamfered. The base 201 is formed of metal or resin having rigidity. The upper surface of the base 201 is formed with a switching member storage recess 2011 that is concave in a stepped shape downward and parallel to the upper surface in the longitudinal direction (from the front to the back). Furthermore, the base 201 is formed with top plate connection screw holes 2012 arranged near each of the four corners of the upper surface, and a guide member screw hole 2013 arranged on the bottom surface of the switching member storage recess 2011 as screw holes. The base 201 has an opening on the operation side (front side) which is one side in the longitudinal direction, and is provided with a switching member biasing spring accommodating section 2014 which is a cylindrical hole that is concave toward the other side (rear side). A switching member biasing spring 206 that biases the upper surface of the base 201 in a direction parallel to the longitudinal direction is accommodated in the switching member biasing spring accommodating section 2014. The base 201 has an opening on the upper surface of the switching member storage recess 2011, and is provided with a locking member biasing spring accommodating section 2015 which is a cylindrical hole concave downward. The base 201 also has a locking member guiding section 2016 formed on a part of the circumferential surface of the locking member biasing spring accommodating section 2015 on the opening side, the locking member guiding section 2016 being a groove in the up-down direction (the overlapping direction of the top plate 202 and the base 201) on a part of the circumferential surface. The locking member guiding section 2016 is a groove having a smaller diameter and a shallower depth in the downward direction than the locking member biasing spring accommodating section 2015. The opening of the locking member biasing spring accommodating section 2015 is formed near the center of the base 201 when viewed from above, and the locking member guiding section 2016 is provided on the opposite side of the locking member biasing spring accommodating section 2015 to the switching member biasing spring accommodating section 2014 when viewed from above. In this switching member biasing spring accommodation section 2014, a locking member biasing spring 207 that biases the top plate 202 and the base 201 in the overlapping direction (up and down direction) is stored on the bottom side, and a locking member 205 is stored on the upper side of the locking member biasing spring 207 so that it can be protruded / retracted by the locking member biasing spring 207.

[0017] FIG. 6 is a cross-sectional view of the top plate 202 and the base 201 taken along the line BB in FIG. 3a. The top plate 202 has a generally columnar shape with a flat upper surface in appearance. The top plate 202 of this embodiment has a generally rectangular parallelepiped shape with each vertex chamfered. The top plate 202 is formed of metal or resin having rigidity. The top plate 202 has a top plate position fixing convex part 2021 (see Fig. 3a and Fig. 4) that is stepped downward at the center of the bottom surface. The top plate position fixing convex part 2021 is formed so that its width in the lateral direction (short side direction of the base 201) is smaller than the width in the lateral direction (short side direction of the base 201) of the switching member storage recess 2011 and its height is smaller than the depth of the switching member storage recess 2011. Furthermore, the size of the top plate 202 in a plan view (viewed in the overlapping direction with the base 201) is formed to be approximately the same as the size of the base 201 in a plan view (viewed in the overlapping direction with the top plate 202). The top plate 202 has main body connection screw holes 2022 that are arranged near each of the four corners of the top surface and penetrate in the vertical direction (overlapping direction with the base 201) as screw holes. The main body connection screw holes 2022 are formed so that the main body connection screw holes 2022 communicate with the top plate connection screw holes 2012 corresponding to each main body connection screw hole 2022 when the top surface of the base 201 and the bottom surface of the top plate 202 are aligned. In addition, the top plate 202 has an insert insertion hole 2023 that penetrates straight from the top surface near the center toward the bottom surface (overlapping direction with the base 201) on the top surface. The circumference of the insert insertion hole 2023 has a diameter one size larger than the outer periphery of the body part 301 of the insert 300.

[0018] The base 201 and the top plate 202 are fixed to each other by a top plate fixing screw 208 that is inserted from the main body connecting screw hole 2022 to the top plate connecting screw hole 2012 and screwed in. At this time, the top plate position fixing convex part 2021 is inserted into the switching member storage concave part 2011, and the top plate 202 is positioned in a position parallel to the upper surface with respect to the base 201. The top plate fixing screw 208 has a threaded part 208b that is inserted from the main body connecting screw hole 2022 to the top plate connecting screw hole 2012 and is screwed into the main body connecting screw hole 2022 and the top plate connecting screw hole 2012, and a screw thread 208a that has a diameter larger than that of the threaded part 208b in the outer circumferential direction and is formed on the top plate side end of the threaded part 208b. The main body connecting screw hole 2022 is formed with a screw threading portion 2022b into which the screw portion 208b of the top plate fixing screw 208 is screwed, and a screw thread insertion portion 2022a into which the screw thread 208a is inserted.

[0019] <Fastening and releasing unit> As shown in FIG. 4, the fastening / releasing unit 20 has a guide member 204 fixed to a base 201, a switching member 203 that slides while being guided by the guide member 204, and a switching member biasing spring 206 that biases the switching member 203 in the sliding direction.

[0020] <Switching member> 7a is a plan view of the switching member 203, FIG. 7b is a left side view of the switching member 203, and FIG. 7c is a left sectional view of the switching member 203. As shown in FIG. The switching member 203 is a thin plate having a thickness in the vertical direction (overlapping direction of the base 201 and the top plate 202) and a longitudinal shape in the longitudinal direction (front-rear direction) of the base 201, and has an inverted L shape with an end on the operation side (front side) bent downward. That is, the switching member 203 has a flat plate portion 2031 that is long in the longitudinal direction (front-rear direction) of the base 201 and a spring abutment portion 2032 that is continuous with the flat plate portion 2031 and bent at a right angle downward (toward the base 201) at one end on the operation side. The switching member 203 is also formed of a metal having rigidity. The switching member 203 has a switching gap 2033 near the center of the flat plate portion 2031, and an elliptical screw insertion hole 2034 behind the switching gap 2033 (opposite the operation side). The screw insertion hole 2034 is formed such that its length in the longitudinal direction of the switching member 203 is longer than the diameter of the screw head of a guide member fixing screw 209 (described later) by the distance the switching member 203 slides.

[0021] The switching gap 2033 has a wide portion 2035 having a diameter that allows the tip portion 304 (described in detail later) of the insert 300 to be inserted, and a narrow portion 2036 having a diameter smaller than that of the wide portion 2035 and that does not allow the insertion portion of the insert 300 to be inserted. The boundary between the wide portion 2035 of the switching member 203 forms an engagement recess 2035a that allows the tip portion 304 of the insert 300 to be inserted and removed, and the boundary between the narrow portion 2036 forms an engagement protrusion 2036a that abuts or is close to the constricted portion 303 of the insert 300 to fix the tip portion 304 so that it does not pull out. In addition, a switching locking member insertion recess 2037 is formed at both ends of the wide portion 2035 in the width direction (short side direction of the base 201), with the hole partially widening in the width direction (side direction).

[0022] <Guide parts> 8a is a plan view of guide member 204, and FIG. 8b is a front view of guide member 204 and a left sectional view of guide member 204. FIG. The guide member 204 has a thickness in the up-down direction (overlapping direction of the base 201 and the top plate 202) and is formed in a thin plate shape having a longitudinal shape in the longitudinal direction (front-rear direction) of the base 201. The guide member 204 has both side ends near both ends in the longitudinal direction folded to have two front upper surface portions 2041 and two rear upper surface portions 2042. That is, the guide member 204 has a lower surface portion 2043 whose longitudinal direction is the front-rear direction, and a front upper surface portion 2041 and a rear upper surface portion 2042 provided above both sides in the width direction near both ends of the lower surface portion 2043 in the longitudinal direction. The front upper surface portion 2041 and the rear upper surface portion 2042 are configured parallel to the lower surface portion 2043 so that the portions extending in the width direction from both end portions near both longitudinal ends of the lower surface portion 2043 are bent 180 degrees upward on the base side to face the lower surface portion 2043. An insertion portion 2044 is formed by the space between the lower surface portion 2043 and the front upper surface portion 2041 and the rear upper surface portion 2042.

[0023] The flat plate portion 2031 of the switching member 203 is inserted into the insertion portion 2044. In the insertion portion 2044, the distance between the front upper surface portion 2041 and the rear upper surface portion 2042 and the lower surface portion 2043 is the same as or slightly wider than the thickness of the flat plate portion 2031 of the switching member 203, and the distance between the curved portions of the front upper surface portion 2041 on both sides in the width direction and the distance between the curved portions of the rear upper surface portion 2042 are the same as or slightly wider than the width of the switching member 203. As a result, the switching member 203 is guided by the front upper surface portion 2041, the rear upper surface portion 2042, and the lower surface portion 2043 so as not to tilt in the thickness direction, and is guided by the curved portions of the front upper surface portion 2041 and the rear upper surface portion 2042 so as not to tilt in the width direction, and slides in the longitudinal direction.

[0024] The lower surface 2043 of the guide member 204 has a guide insert body insertion hole 2045 near the center, and a screw insertion hole 2046 behind this guide insert body insertion hole 2045 (opposite the operation side). The guide insert body insertion hole 2045 is approximately circular, and a guide locking member insertion recess 2047 that widens in the width direction (side direction) is formed behind the center of both ends in the width direction (opposite the operation side). The diameter of the guide insert body insertion hole 2045 is formed slightly larger than the diameter of the tip portion 304 of the insert 300 (described in detail later).

[0025] When the switching member 203 and the above-mentioned guide member 204 are overlapped, the position and size of the guide insert insertion hole 2045 of the guide member 204 and the switching gap 2033 of the switching member 203 are the same. Therefore, the switching member 203 and the guide member 204 are arranged such that, in the released state, the guide insert insertion hole 2045 of the guide member 204 communicates with the switching gap 2033 of the switching member 203, the guide locking member insertion recess 2047 of the guide member 204 communicates with the switching locking member insertion recess 2037 of the switching member 203, and the screw insertion hole 2046 of the guide member 204 communicates with the screw insertion hole 2034 of the switching member 203.

[0026] The guide member 204 is stored in the switching member storage recess 2011 of the base 201 together with the switching member 203. That is, in the fastening mechanism body 200, the top plate 202 is arranged so as to cover the upper surfaces of the guide member 204 and the flat plate portion 2031 (switching member 203). At this time, the top plate 202 is arranged and sized to cover at least a part of the guide member 204 and the switching member 203. The arrangement and size of the top plate 202 are preferably such that it covers both the front and rear sides of the switching gap 2033 and the guide insert insertion hole 2045 on the upper surfaces of the guide member 204 and the switching member 203, and preferably covers the entire upper surface of the guide member 204. The guide member 204 is fixed to the base 201 by the guide member fixing screw 209 inserted from the screw insertion hole 2046 to the guide member screw hole 2013. At this time, the spring abutment portion 2032 of the switching member 203 is arranged further forward from the front surface of the base 201. Further, the guide inserter insertion hole 2045 of the guide member 204 and the switching member biasing spring receiving portion 2014 of the base 201 are arranged to communicate with each other.

[0027] The switching member biasing spring 206 is a compression spring, and in a natural state, approximately the rear half of the spring is accommodated in the switching member biasing spring accommodating portion 2014. The switching member biasing spring 206 is disposed so that the biasing direction is parallel to the sliding direction of the switching member 203, and the front end portion abuts against the spring abutment portion 2032 of the switching member 203 from the inside. As a result, the switching member biasing spring 206 biases the switching member 203 in the direction in which the spring abutment portion 2032 protrudes (forward). The biasing force of the switching member biasing spring 206 is strong enough to contract when intentionally pushed by a human hand, and is strong enough not to contract when a player playing the gaming machine 100 operates the gaming machine constituent member 110 or makes an unexpected contact with it.

[0028] The thus formed switching member 203, guide member 204, and switching member biasing spring 206 constitute the fastening / releasing unit 20. The switching member 203 inserted into the insertion portion 2044 of the guide member 204 is held by the guide member 204 so as to be slidable in the longitudinal direction (front-rear direction) relative to the base 201. At this time, the longitudinal movement range of the switching member 203 is limited to a range in which the head of the guide member fixing screw 209 can move relatively in the elliptical screw insertion hole 2034 with respect to the sliding movement of the switching member 203. That is, when the head of the guide member fixing screw 209 is at the rear end of the screw insertion hole 2034, the switching member 203 is in a state of sliding to the most operating side (forward), and when the guide member fixing screw 209 is at the most front end of the screw insertion hole 2034, the switching member 203 is in a state of sliding to the opposite side (rear) of the most operating side. The switching member 203 is slidable, and the spring abutment portion 2032 of the switching member 203 is urged in the protruding direction (operating side) by the switching member urging spring 206. The head of the guide member fixing screw 209 abuts against the rear end of the screw insertion hole 2034, thereby restricting it from protruding any further. When the spring abutment portion 2032 is pressed in from this state, the switching member 203 slides in the backward direction (opposite the operating side). During this time, the switching member 203 is biased by the switching member biasing spring 206, so when the pressing is stopped or the like and the switching member 203 is released, the switching member 203 moves in the protruding direction (operating side) and stops at a position where the head of the guide member fixing screw 209 abuts against the rear end of the screw insertion hole 2034.

[0029] <Slide fixing release unit>> The slide fixing / releasing unit 30 is composed of a locking member 205 and a locking member biasing spring 207 shown in FIG.

[0030] <Locking member> FIG. 9 is a side view of the locking member 205. The locking member 205 is a thin plate having a thickness in the vertical direction, and has a bottom surface 205b and a side surface 205a whose both end portions rise upward from the bottom surface 205b. The side surface 205a also has a locking protrusion 2051 whose upper end portion is partially convex in the upward direction. The width between the locking protrusions 2051 is narrower than the width of the switching member 203, and is configured to be larger than the width (diameter) of the tip portion 304 of the insertion body 300. The bottom surface portion 205b has a guide protrusion 2052 that protrudes rearward (opposite the operation side).

[0031] The locking member 205 is accommodated in an upper portion of the switching member biasing spring accommodating portion 2014 of the base 201. As shown in Fig. 4, the guide protrusion 2052 is inserted into the locking member guiding portion 2016 of the switching member biasing spring accommodating portion 2014, and guides the vertical movement of the locking member 205 (movement in the overlapping direction of the top plate 202 and the base 201) along the locking member guiding portion 2016. Therefore, the locking member 205 can move in the vertical direction (the protruding / retracting direction of the locking member 205) within the switching member biasing spring accommodating portion 2014 so that the guide protrusion 2052 follows the locking member guiding portion 2016, and the bottom surface portion 205b is restricted from rotating in the surface direction of the overlapping surface of the top plate 202 and the base 201.

[0032] <Latching member biasing spring> The locking member biasing spring 207 is a compression spring, and is housed in a locking member biasing spring housing portion 2015, which is a hole long in the overlapping direction of the top plate 202 and the base 201, with the biasing force directed in the overlapping direction. The upper end of the locking member biasing spring 207 abuts against the bottom of the locking member 205, and biases the locking member 205 upward (in the protruding direction of the locking member 205). The biasing force of the locking member biasing spring 207 is strong enough to contract when intentionally pushed by a human hand, and is not strong enough to contract when a player playing with the gaming machine 100 operates the gaming machine constituent member 110 or makes an unexpected contact with the same. The locking member 205 and the locking member biasing spring 207 thus formed constitute the slide fixing / releasing unit 30.

[0033] <insert> The insert 300 has a cylindrical body portion 301, an upper end portion 302 which is formed continuously upward from the body portion 301 and has a larger diameter than the body portion 301, a constricted portion 303 which is formed continuously downward from the body portion 301 and has a smaller diameter than the body portion 301, and a tip portion 304 which is formed continuously downward from the constricted portion 303 and has a smaller diameter than the body portion 301 and a larger diameter than the constricted portion 303.

[0034] The diameter of the constricted portion 303 is slightly smaller than the width of the narrow portion 2036 of the switching member 203. In addition, the length of the constricted portion 303 in the vertical direction is longer than the sum of the thickness of the switching member 203 and the thickness of the guide member 204.

[0035] The tip portion 304 is formed of a cylindrical upper portion 3041 and a lower portion 3042 that is formed continuously downward from the upper portion 3041 while inclining inwardly from the upper portion 3041. A bottom portion 3043, which is also the lower end surface of the insert 300, is formed at the lower end surface of the lower portion 3042. The tip portion 304 is formed such that the diameter of the upper portion 3041 is larger than the width of the narrow portion 2036 of the switching member 203 and smaller than the width of the wide portion 2035 of the switching member 203 and the diameter (width) of the guide insert insertion hole 2045 of the guide member 204 (excluding the guide locking member insertion recess 2047 portion).

[0036] By the functions of the fastening / release unit 20 and the slide fixing / release unit 30 thus formed, the fastening device 1 can transition between a released state in which the insert 300 can be removed from the fastening mechanism body 200, and a fastened state in which the insert 300 is fixed to the fastening mechanism body 200. The released state and the fastened state will be described below.

[0037] <Released state> 2 and 3, when the fastening device 1 is in the released state, the switching member 203 is in a state of sliding backward (retracted side). At this time, the wide portion 2035 of the switching member 203 is located above the locking member biasing spring accommodating portion 2015, so that the tip portion 304 of the insertion body 300 can pass through the wide portion 2035 and come out upward. Then, the locking member biasing spring 207 biases the locking member 205 toward the insertion body 300, so that the biasing force causes the tip portion 304 of the insertion body 300 to be pulled out from the locking member biasing spring accommodating portion 2015. As a result, the insertion body 300 is pulled out from the fastening mechanism main body 200.

[0038] At this time, the switching locking member insertion recess 2037 (see FIG. 7a) of the switching member 203 and the guide locking member insertion recess 2047 (see FIG. 8a) of the guide member 204 are in an overlapping state. Therefore, the locking protrusion 2051 of the locking member 205 is inserted (engaged) into the overlapping switching locking member insertion recess 2037 and the guide locking member insertion recess 2047, and the switching member 203 is locked. Therefore, the switching member 203 is biased forward (front direction, longitudinal direction) by the switching member biasing spring 206, but the longitudinal movement is restricted and fixed by the locking protrusion 2051 inserted into the switching locking member insertion recess 2037. Therefore, even if the tip portion 304 of the inserting body 300 is completely removed from the fastening mechanism main body 200, the switching member 203 does not slide and the fastening device 1 maintains the released state.

[0039] <Fixed state> FIG. 11 is a cross-sectional view of the fastening device 1 in a fastened state. The fastening device 1 transitions to a fastened state by inserting the insert 300 from above into the fastening mechanism body 200 in the released state. More specifically, when the fastening mechanism body 200 is in the released state, the insert 300 is inserted into the insert insertion hole 2023 of the top plate 202 from the tip 304. The tip 304 is moved downward and inserted into the wide portion 2035 of the switching member 203 communicating with the insert insertion hole 2023 of the top plate 202 and the guide insert insertion hole 2045 of the guide member 204 communicating with the wide portion 2035, and is further moved downward and inserted into the locking member biasing spring housing portion 2015 of the base 201. Then, the tip of the insert 300 (tip 304) abuts against the bottom surface portion 205b of the locking member 205 housed in the locking member biasing spring housing portion 2015.

[0040] When the insertion body 300 is further moved (pushed) downward from this state, the locking member biasing spring 207 contracts, and the locking member 205 moves downward. At this time, the biasing force that the locking member 205 receives from the locking member biasing spring 207 increases as the locking member 205 moves downward. Then, when the locking protrusion 2051 of the locking member 205 moves downward until it is completely removed from the switching locking member insertion recess 2037 of the switching member 203, the switching member 203 biased forward by the switching member biasing spring 206 slides forward, and the fastening device 1 enters the fastened state.

[0041] When the fastening device 1 is in the fastened state, the inserting body 300 is in a state where the constricted portion 303 is inserted into the narrow width portion 2036 of the switching member 203. Therefore, the inserting body 300 is in a state where the movement in the up-down direction (the direction of inserting / removing the inserting body 300) is restricted. Also, when the fastening device 1 is in the fastened state, the inserting body 300 is in a state where the tip portion 304 is inserted into the guide inserting body insertion hole 2045 of the guide member 204. Therefore, the inserting body 300 is in a state where the movement in the front-rear direction and the left-right direction is restricted. That is, when the fastening device 1 is in the fastened state, the insert 300 is fixed to the fastening mechanism body 200 .

[0042] Furthermore, the fastening device 1 in the fastened state has a predetermined load-bearing capacity for a load applied to a fastening portion between the fastening mechanism body 200 and the insert body 300. This load-bearing capacity is obtained by the strength of the guide member 204 and the switching member 203, the strength of the insert body 300, and the strength of the top plate 202 and the base 201 that sandwich the guide member 204 and the switching member 203 so as to prevent breakage. In this embodiment, the fastening device 1 has a load-bearing capacity of 70 kgf or more against a stress (shear stress) perpendicular to the insertion direction of the insert body 300 into the fastening mechanism body 200. Also, the fastening device 1 has a load-bearing capacity of 130 kgf or more against a stress (tensile stress) parallel to the insertion direction of the insert body 300 into the fastening mechanism body 200.

[0043] Furthermore, when the fastening device 1 is in the fastened state, the switching member 203 slides forward and is therefore in a state of protruding forward of the base 201 . At this time, when the switching member 203 is pushed backward (towards the main body) by, for example, pressing the spring abutment portion 2032 from the front side, the fastening device 1 transitions to the released state. That is, when the spring abutment portion 2032 is used as an operating portion to be pushed from the front side towards the base 201, the fastening device 1 transitions to the released state. In detail, when the switching member 203 is pushed backward (longitudinal direction) (sliding movement), the position adjacent to (or the abutment position of) the constricted portion 303 of the switching gap 2033 of the switching member 203 into which the constricted portion 303 of the insertion body 300 is inserted transitions from the narrow portion 2036 to the wide portion 2035. Then, when the switching member 203 moves to the same position as in the released state, the proximity position of the constricted portion 303 relative to the switching gap 2033 moves completely from the narrow portion 2036 to the wide portion 2035, and the tip portion 304 of the inserting body 300 is in a released state in which it can be removed from the wide portion 2035. Then, the locking member 205 biased by the locking member biasing spring 207 moves upward. That is, the locking protrusion 2051 is inserted into the switching locking member insertion recess 2037, and the sliding movement of the switching member 203 in the front-rear direction is restricted. At this time, the upward movement of the inserting body 300 is not restricted, and it can be removed (pulled out) from the fastening mechanism main body 200 by moving it in the opposite direction (upward) to the direction of insertion.

[0044] That is, the transition between the fastened state and the released state of the fastening device 1 is controlled by the switching member biasing spring 206 and the locking member biasing spring 207 expanding and contracting relative to each other.

[0045] Therefore, as shown in Figure 2, by fixing the fastening mechanism main body 200 to the inner frame 102 of the gaming machine 100 and fixing the insert body 300 to the gaming machine component 110, the inner frame 102 and the gaming machine component 110 can be fastened and separated by the fastening device 1.

[0046] With the above-described configuration, it is possible to provide a fastening device that allows components of an amusement machine to be easily attached and detached. The fastening device 1 is composed of a fastening mechanism main body 200 fixed to the inner frame 102 and an insert body 300 fixed to the gaming machine component 110, and the fastened state and released state of the fastening device 1 are controlled by mutual expansion and contraction of two springs, a switching member biasing spring 206 that biases the switching member 203 and a locking member biasing spring 207 that biases the locking member 205. With this configuration, if there is a mechanism for mutually expanding and contracting the two springs, the inner frame 102 and the gaming machine component 110 can be fixed and detached (attached and detached). Therefore, the internal structure of the fastening device 1 can be simplified. In addition, if the internal structure of the fastening device 1 is simple, the fastened state and released state can be transitioned by a simple operation, and the inner frame 102 and the gaming machine component 110 can be easily fixed and detached (attached and detached).

[0047] Moreover, the fastening device 1 is configured such that the insert 300 is inserted into the fastening mechanism main body 200 to fasten them together, and the spring contact portion 2032 corresponding to the operation portion protruding from the fastening mechanism main body 200 is pressed to separate them. With this configuration, the user can attach the gaming machine component 110 to the inner frame 102 simply by inserting the insert 300 fixed to the gaming machine component 110 into the fastening mechanism main body 200 fixed to the inner frame 102, and can remove the gaming machine component 110 from the inner frame 102 simply by pressing the spring contact portion 2032. In other words, the inner frame 102 and the gaming machine component 110 can be fixed and separated (attached and detached) more easily.

[0048] Moreover, the biasing force of the switching member biasing spring 206 and the locking member biasing spring 207 is strong enough to contract when intentionally pushed by a human hand, but not enough to contract when the game-machine component 110 is operated or accidentally contacted by a player playing the game machine 100. With this configuration, the fastening device 1 does not transition from the fastened state to the released state even if the game-machine component 110 is operated or accidentally contacted by a player playing the game machine 100, and it is possible to prevent the game-machine component 110 from unintentionally falling off the inner frame 102.

[0049] Moreover, the fastening mechanism body 200 includes a top plate 202 fixed above the base 201, and the top plate 202 is arranged so as to cover at least a part of the guide member 204 and the switching member 203 stored in the switching member storage recess 2011 of the base 201. With this configuration, when a load is applied in a direction perpendicular to the insertion direction of the insertion body 300 into the fastening mechanism body 200, it is possible to prevent the guide member 204 and the switching member 203 from coming off the base 201. In other words, it is possible to improve the load-bearing performance of the fastening device 1.

[0050] In addition, since the switching member 203 slides with the plate-shaped guide member 204 overlapping each other, and the locking protrusion 2051 of the locking member 205 is inserted into the switching locking member insertion recess 2037 (see FIG. 7a) of the switching member 203 and the guide locking member insertion recess 2047 (see FIG. 8a) of the guide member 204 to lock the switching member 203 from sliding, stable operation is possible and sufficient strength can be obtained. Moreover, since the switching member 203, the guide member 204 and the locking member 205 are made of metal members, higher strength and durability can be obtained.

[0051] Furthermore, in the fastening / releasing unit 20, since the switching member biasing spring 206 constantly biases the switching member 203 in the protruding direction, once the switching member 203 is in the protruding released state, this released state can be maintained. Therefore, when inserting the inserting body 300 into the fastening mechanism body 200, it is possible to prevent a situation in which the tip portion 304 of the inserting body 300 hits the narrow portion 2036 of the switching gap 2033 of the switching member 203 when the switching member 203 is in the fastened state and the inserting body 300 cannot be inserted.

[0052] In addition, since the locking member 205 and the locking member biasing spring 207 of the slide fixation / release unit 30 bias the insertion body 300 in the direction of pulling it out, when the switching member 203 moves to the release position, the biasing force of the locking member biasing spring 207 causes the insertion body 300 to pop out and come out of the fastening mechanism main body 200. Therefore, the release can be immediately seen, and a favorable operating feel can be obtained.

[0053] Furthermore, since the tip 304 of the insert 300 pushes in near the center of the locking member 205 and the locking protrusion 2051 of the locking member 205 is positioned around the tip 304, the insert 300 can stably push in the locking member 205 regardless of the weight of the gaming machine components, and in the released state the locking protrusion 2051 can stably perform its function of fixing the switching member 203 without allowing it to slide.

[0054] The present invention is not limited to the above-described embodiment, but can take various forms. For example, in this embodiment, the fastening mechanism main body 200 is fixed to the inner frame 102 and the insert body 300 is fixed to the gaming machine component 110, but the opposite may be true: the insert body 300 is fixed to the inner frame 102 and the fastening mechanism main body 200 is fixed to the gaming machine component 110.

[0055] In this embodiment, the switching member biasing spring 206 is a push spring, but the switching member biasing spring 206 may be a pull spring. In this case, the arrangement of the wide portion 2035 and the narrow portion 2036 in the front-rear direction is reversed. In addition, the switching member 203 is biased backward with the spring abutment portion 2032 fixed to the front end of the switching member biasing spring 206. Then, by inserting the insert 300 into the fastening mechanism main body 200 in the released state, the switching member 203 slides backward and the fastening device 1 is in the fastened state, and by pulling the spring abutment portion 2032 (operation portion) of the switching member 203 in the forward direction (toward the outer periphery of the base 201), the switching member 203 slides forward and the fastening device 1 transitions to the released state. With this configuration, even if the player or user makes contact with the spring abutment portion 2032 in such a way that it is pushed in unexpectedly, the fastening device 1 will not transition to the released state. Therefore, it is possible to prevent the fastening device 1 from being unintentionally released due to an erroneous operation, and the gaming machine component 110 from falling off from the inner frame 102.

[0056] The game machine described in the present invention corresponds to the inner frame 102 described in the embodiment, and the same applies below. The recess corresponds to the locking member biasing spring housing portion 2015, The switching member biasing body corresponds to the switching member biasing spring 206. The locking member biasing body corresponds to the locking member biasing spring 207. The locking portion corresponds to the locking protrusion 2051, The engagement portion corresponds to the switching locking member insertion recess 2037, but is not limited to the configuration of the above-mentioned embodiment, and many other embodiments can be obtained.
