【発明の詳細な説明】〈産業上の利用分野〉本発明は、各種遊技機能装置を備えた開閉体を左右一側方に設けた蝶番機構に
より開閉自在に支持体で支持するようにした遊技機に関するものである。〈従来の技術〉従来の遊技機に設ける蝶番機構としては、一方の開閉具に回動軸を立設すると
ともに、他方の開閉具に回動軸を貫通させ得る回動孔を開設し、それぞれの開閉
具を開閉体及び支持体へ予め配設し、回動軸の先端から回動孔へ挿入されること
により支持体に対して開閉体が回動自在な状態に蝶着されるものが用いられてい
た。また、遊技機において、蝶番機構を用いて開閉自在に取り付ける開閉体として
は、各種遊技機能装置を備える遊技盤収納フレームや、該遊技盤収納フレームを
支持する支持体である共に機枠に開閉自在に支持される前面枠や、この前面枠に
開閉自在に取り付けられるガラス枠（遊技盤の前面に臨むガラス板を支持する枠
体）や前面パネル（球供給皿が取り付けられるパネル体）等があり、これらの開
閉体を開くことにより、各種遊技機能装置を含む内部機構の保守や修理を容易に
行えるようになっている。〈発明が解決しようとする課題〉しかしながら、各種遊技装置を備えることで比較的重量がある開閉体を支持体
へ取り付ける場合、その重量を安定して支えるために複数の蝶番機構を一側方に
並設しているため、これら蝶番機構における回動軸と回動孔とを適正に嵌合させ
て開閉体を支持体へ取り付ける作業は、甚だ煩雑なものとなってしまうのである
。すなわち、遊技機の製造時や遊技機のメンテナンス時には、支持体に対して開閉体を着脱する作業が必要となり、特に開閉体を
支持体に取り付けるために回動軸と回動孔とを嵌合させる場合には、重量のある
開閉体を持ち上げて回動孔の直上方へ回動軸を位置させるように微妙な配置調整
を行って、回動軸を回動孔へ落とし込まなければならないので、複数設けた全て
の蝶番機構における回動軸と回動孔とを一度に嵌合させるためには、相当の熟練
が必要なのである。従って、標準的に用いられている蝶番を以て蝶番機構とした遊技機においては

The opening / closing member is disposed in advance on the opening / closing body and the support, and the opening / closing body is hinged so that the opening / closing body is rotatable with respect to the support by being inserted into the rotation hole from the tip of the rotation shaft. Was used. Further, in the gaming machine, the opening / closing body which can be freely opened and closed by using a hinge mechanism is a game board storage frame provided with various game function devices and a support for supporting the game board storage frame. There is a front frame supported on the front frame, a glass frame that can be freely opened and closed on this front frame (a frame that supports a glass plate facing the front of the game board), a front panel (a panel body on which a ball supply tray is mounted), and the like. By opening these open / close bodies, maintenance and repair of internal mechanisms including various game function devices can be easily performed. <Problems to be Solved by the Invention> However, when a relatively heavy opening / closing body is attached to the support by providing various gaming devices, a plurality of hinge mechanisms are provided on one side to stably support the weight. Since they are juxtaposed, the work of properly fitting the turning shaft and the turning hole in these hinge mechanisms and attaching the opening / closing body to the support becomes extremely complicated. That is, when manufacturing a gaming machine or performing maintenance on the gaming machine, it is necessary to attach and detach the opening / closing body to / from the support, and in particular, to fit the rotating shaft and the rotating hole to attach the opening / closing body to the support. In this case, it is necessary to lift the heavy opening / closing body and finely adjust the arrangement so that the rotating shaft is positioned immediately above the rotating hole, and drop the rotating shaft into the rotating hole. In order to fit the pivot shafts and the pivot holes in all the hinge mechanisms provided at a time, a considerable skill is required. Therefore, in a gaming machine having a hinge mechanism with a hinge used as a standard, the efficiency of manufacturing, maintenance, and repair operations is reduced. <Means for Solving the Problems> The present invention has been proposed in view of the above, and has an opening / closing body (e.g., a game board 11, a back mechanism board 10, a ball storage tank 16, and the like) provided with various game function devices. for example, a hinge mechanism provided with a backing mechanism plate 10) on one lateral side (e.g., I detachable der by the one rotary support brackets 9a and the second type of pivot support bracket 9b), and open and close In a gaming machine (for example, a pachinko machine 1 or the like) which is freely supported by a support (for example, the machine frame 2, the game board storage frame 8 or the like), a first horizontal plate (for example, A first opening / closing tool (for example, a first metal fitting 21a) having a columnar rotating shaft (for example, a supporting shaft 20) erected on the supporting piece 19), and a second horizontal plate (for example, a horizontally extending plate). For example, the rotation shaft of the first opening / closing tool can be penetrated through the horizontal portion 23 or the like. Thereby opening the Doana (25a), and the outer edge side for introducing the pivot axis of the first opening and closing member to pivot hole from the outer edge of the horizontal plate is larger than the shaft diameter of the rotation shaft rotates
A rotating shaft introduction space (for example, a support shaft introduction space 26a) that narrows toward the hole is formed, and a communication region where the rotation shaft introduction space and the rotation hole communicate with each other is defined as a shaft of the rotation shaft. In the normal state smaller than the diameter, when the rotating shaft is introduced , the rotating shaft expands the communication region.
In order to be able to change to the introduction state that can be introduced into the rotation hole, and to remove the opening and closing body,
When the rotating shaft is to escape from the rotating hole, the opening / closing body is substantially perpendicular to the horizontal plate.
Escape possible second closing member without extending the communication area by successfully move in a direction (e.g., second
And a hinge mechanism (e.g., a first-type rotation support metal 9a) including at least one metal support 22a). <Operation> The second horizontal plate is formed by setting the communication area of the second opening / closing tool that communicates the turning shaft introduction space with the turning hole so that the turning shaft of the first opening / closing tool can be introduced. The rotation shaft can be fitted into the rotation hole from the side of the shaft, and when the communication region returns to the normal state in which the communication area is smaller than the rotation shaft, the rotation shaft does not come off from the rotation hole. The moving shaft is rotatably held in the turning hole. <Example> Hereinafter, an example of the present invention will be described with reference to the drawings. As shown in FIG. 1 and FIG. 2, a pachinko machine 1 as a gaming machine has a front frame 5 having a window 4 provided on one side of a machine frame 2 by hinges 3 and 3 so as to be freely opened and closed.

The above-described pachinko machine 1 has a large number of configurations in which various opening and closing bodies are supported by a support so as to be openable and closable by a hinge mechanism provided on one side of the left and right sides. For example, when the front frame 5 is an opening and closing body, the machine frame 2 is a support, when the glass frame 6 is an opening and closing body, the front frame 5 is a support, and when the back mechanism panel 10 is an opening and closing body, the game board storage frame 8 is supported. It becomes a body. In the following description, only an example in which the game board storage frame 8 is used as a support and the back mechanism board 10 is used as an opening / closing body and a hinge mechanism is provided. The game board storage frame 8 is a shallow metal frame having an open front surface, and a frame board 12 on which a game board 11 is mounted is attached to a lower portion of the inside thereof.
The upper part of the game board storage space is provided, and an opening 14 is provided on the back side of the game board 11 for receiving the prize ball collecting gutter 13 attached to the back of the game board 11. In order to fix the game board 11 mounted in the game board storage frame 8, the locking levers of the game board locking members 15, 15 disposed on the side portions of the game board storage frame 8 are manually rotated. By locking the tip end locking portion of the locking lever to the side edge of the game board, the game is fastened. The back mechanism board 10 attached to the back of the game board storage frame 8 is provided with a back mechanism composed of a group of various game function devices in a synthetic resin frame. In the embodiment shown in the drawings, a ball storage tank is provided. 16, a back mechanism such as a ball guide gutter, a prize ball discharge device, a prize ball flow down gutter, etc. is provided, and a prize ball is received on the lower front surface of the opening 14 where the prize ball collection gutter 13 of the game board 11 enters and flows down. A ball receiving shelf 17 for guiding to the control device is formed.
A winning ball flow down controller is provided at the lower end of the slope. A pivot support 9 as a hinge mechanism for attaching the back mechanism board 10 to the game board storage frame 8 is attached to the hinges 3 and 3 of the glass frame 6 and the front frame 5, and the embodiment shown in FIG. Then, there are a first kind of rotation support fitting 9a that can be attached with one touch, and a second kind of rotation support fitting 9b similar to a conventional fitting, and the first kind of rotation support fitting 9a is moved upward. The second kind of rotation support fitting 9b is attached below. As shown in FIGS. 3 to 5, the first embodiment of the first kind of rotation support fitting 9a as a hinge mechanism provided in the game machine according to the present invention is a lower end edge of the vertical fastening piece 18. As shown in FIGS. And a first metal fitting 21a having a support shaft 20 standing upright on the support piece 19, and a columnar rotating shaft mounted on a first horizontal plate extending in the horizontal direction. And a second metal fitting 22 fitted to the support shaft 20 of the first metal fitting 21a.
a is a second opening / closing tool having a second horizontal plate extending in the horizontal direction, in which a turning hole that allows the turning shaft of the first opening / closing tool to penetrate is opened. The second metal fitting 22a is formed by molding a material having elasticity such as a steel plate, and has a fastening piece 24 erected at a base end of a substantially horizontal portion 23 and a tip end having a size capable of penetrating the support shaft 20. The pivot hole 25a is opened, and the width of the portion communicating with the pivot hole 25a from the pivot hole 25a to one side edge is slightly smaller than the diameter of the support shaft 20, and gradually widens, that is, A support shaft introduction space 26 gradually narrowing from an outer opening wider than the diameter of the support shaft 20 is formed, and a slit 27 is formed along the support shaft introduction space 26a beside the support shaft introduction space 26a. It is notched so that the side edge portion of the support shaft introduction space 26a has an appropriate spring property. Therefore, the second metal fitting 22a, which is the second opening / closing tool, forms a turning axis introduction space for introducing the turning axis of the first opening / closing tool from the outer edge of the horizontal plate to the turning hole. The communication area in which the hollow portion and the rotation hole communicate can be changed between a normal state in which the diameter of the rotation axis is smaller than the diameter of the rotation axis and an introduction state in which the rotation axis can be introduced. In order to attach the second metal fitting 22a to the back mechanism board 10, the fastening piece 24 is fixed to the back mechanism board 10 with a screw or the like, and the horizontal portion 23 is laterally protruded from the side surface of the back mechanism board 10. Then, as shown in FIG. 4, the support shaft introduction space 26a of the second metal fitting 22a is formed.
With the outer opening facing the support shaft 20 of the first metal fitting 21a and the outer opening of the support shaft introduction space 26a positioned slightly higher than the support piece 19 of the first metal fitting 21a. When the support shaft 20 is advanced to the game board storage frame 8 side, the support shaft 20 enters the outer opening of the support shaft introduction space 26a, and when the second metal fitting 22a is further pressed forward, the support shaft 20 is supported by a wedge action. The side edge portion of the introduction space 26a is bent and bent toward the slit 27, and the support shaft introduction space 26a is bent.
The width of is expanded (introduction state). Then, the second bracket 22a is further pressed forward to move the support shaft 20 to the support shaft introduction space 2.
6A, the support shaft 20 passes through the narrowest portion of the support shaft introduction space 26a and fits into the rotation hole 25a. When the support shaft 20 is fitted into the rotation hole 25a, the side edge portion of the support shaft introduction space 26a is restored by elastic force, and the support shaft introduction space 26a is returned.
The width of the narrowest portion a is returned to the initial state smaller than the diameter of the support shaft 20 (normal state). Therefore, in this state, even if the second metal fitting 22a is retracted in the horizontal direction and is to be removed, the support shaft 20 cannot pass through the narrowest part of the support shaft introduction space 26a and does not come off. However, the second
When the bracket 22a is raised, the support shaft 20 comes out of the rotation hole 25a, so that the support shaft 20 can be easily removed. As shown in FIG. 6, the second type of rotation support fitting 9b forms a substantially horizontal support piece 29 at the lower end edge of the vertical fastening piece 28, and a guide surface is formed at the tip of the support piece 29. A fixing piece 3 is attached to the base end of a frame-side metal fitting 32 having a support shaft 31 formed with 30 formed thereon standing upward and a turning piece 34 having an insertion hole 33 fitted into the supporting shaft 31 of the frame-side metal fitting 32.
And a mechanical panel-side fitting 36 having the same. In addition, it is desirable to form a guide surface 33 ′ at the lower opening edge of the insertion hole 33 by, for example, salar fir. In order to attach the frame-side bracket 32 to the game board storage frame 8, the fastening piece 28 is attached to the game board storage frame with a screw or the like while the support shaft 31 is positioned on substantially the same vertical line as the support shaft 20 of the first metal fitting 21 a. 8 on the back. Further, in order to attach the mechanism-panel-side bracket 36 to the back mechanism panel 10, the fastening pieces 35 are fixed to the back mechanism panel 10 with screws or the like in a state where the insertion holes 33 are located on the side of the back mechanism panel 10. In order to connect the back mechanism board 10 to the game board storage frame 8, an operator supports the back mechanism board 10 by hand, and first adjusts the position of the mechanism board side bracket 36 of the second type of rotation support bracket 9b. Then, the support shaft 31 of the frame side fitting 32 is inserted into the insertion hole 33 from below. As described above, when the mechanical panel-side bracket 36 and the frame-side bracket 32 are connected first, most of the weight of the back mechanism panel 10 can be hung on the frame-side bracket 32 via the mechanical panel-side bracket 36, and Can reduce the weight that must be supported, and can stabilize the height of the back mechanism board 10. Next, the support shaft introduction space 26 of the first type metal fitting 9a attached to the upper part of the back mechanism panel 10
a to the side of the support shaft 20 of the first metal fitting 21a, and in this state the second opening
When the metal fitting 22a is advanced to the game board storage frame 8 side, the support shaft 20 enters the outside opening of the support shaft introduction space 26a, and when the second metal fitting 22a is further pushed forward, the support shaft 20 becomes empty. When the width of the support shaft introduction space 26a is enlarged by bending the side edge portion of the portion 26a and further pressing the second metal fitting 22a forward, the support shaft 20 passes through the narrowest portion of the support shaft introduction space 26a. It fits in the rotation hole 25a. When the support shaft 20 is fitted into the rotation hole 25a, the back mechanism panel 10 is rotatably supported by the upper and lower rotation support brackets 9a and 9b. Since the board 10 rotates about the upper and lower support shafts 20 and 31, the back mechanism board 10 can be easily opened and closed with respect to the game board storage frame 8. When the back mechanism board 10 is closed until it comes into contact with the back of the game board storage frame 8, the locking tools 37 projecting from the back of the game board storage frame 8 are locked in the engagement holes 38 of the back mechanism board 10. Therefore, the back mechanism panel 10 can be locked in the closed state. When the back mechanism panel 10 is to be opened, the locks of the locking members 37 are released, and the free end of the back mechanism panel 10 may be pulled by hand. When the back mechanism board 10 is opened and then lifted by hand, the support shaft 20 comes out of the rotation hole 25a of the upper second metal fitting 22a and the support shaft 20 is supported from the inside of the insertion hole 33 of the lower mechanism board side metal fitting 36. Since the shaft 31 comes off, the back mechanism board 10 can be easily removed from the game board storage frame 8. As shown in FIGS. 7 to 9, the second embodiment of the first kind of rotation support metal 9a as a hinge mechanism provided in the gaming machine according to the present invention is a lower end edge of a vertical fastening piece 18. As shown in FIGS. A first metal fitting 21b having a substantially horizontal support piece 19 formed thereon and a support shaft 20 standing upright on the support piece 19, and a second metal fitting 22b fitted to the support shaft 20 of the first metal fitting 21b. Consists of The second metal fitting 22b is formed of a metal narrow vertical piece 3 on a side surface of the synthetic resin back mechanism panel 10.
9 and a horizontal piece 40 in which the middle of the vertical piece 39 is bent outward in a substantially horizontal direction and the leading edge is inclined, and a horizontal end is fixed to the back mechanism board 10 along the horizontal piece 40. And a metal piece 41 facing the front end of the horizontal piece 40. The metal piece 41, which is slightly larger than the diameter of the support shaft 20 and has a cutout shape that can penetrate the support shaft 20, is formed. Moving hole 25
b, and by inclining the edge of the metal piece located on the opposite side of the tip inclined edge of the horizontal piece 40 in the direction opposite to the tip inclined edge, introducing the support shaft along the front-rear direction of the game board storage frame 8. The hollow portion 26b is formed, the width of the outer opening of the support shaft introduction hollow portion 26b is sufficiently larger than the diameter of the support shaft 20, and the width of the portion communicating with the rotation hole 25b is larger than the diameter of the support shaft 20. Is also set slightly narrower. In addition, since the vertical piece 39 and the horizontal piece 40 which constitute a part of the support shaft introduction space 26b are made of metal, they have appropriate elasticity. Accordingly, the outer opening of the support shaft introduction space 26b of the second metal fitting 22b faces the side of the support shaft 20 of the first metal fitting 21b, and the outer opening of the support shaft introduction space 26b is supported by the first metal fitting 21b. When the second metal member 22b is advanced to the game board storage frame 8 side in this state, the support shaft 20 enters the outer opening of the support shaft introduction space 26b, and the second metal member 22b is further moved. 22
When b is pressed forward, the support shaft 20 presses the inclined edge of the end of the horizontal piece 40 in the retreating direction (the back mechanism panel side) by a wedge action, so that the vertical piece 39 bends and bends due to elasticity, and the support shaft introduction space. The width of the portion 26b increases (introduction state). Then, the second fitting 22b is further pressed forward to move the support shaft 20 to the support shaft introduction space 2.
When the support shaft 20 moves to the rear of the support shaft 20b, the support shaft 20 passes through the narrowest portion of the support shaft introduction space 26b and fits into the rotation hole 25b. When the support shaft 20 is fitted into the rotation hole 25b,
The vertical piece 39 is returned by the elastic force, and the width of the narrowest part of the support shaft introduction space 26 b is adjusted to the width of the support shaft 2.
Return to the initial state smaller than the diameter of 0 (normal state). Therefore, in this state, even if the second metal fitting 22b is retreated in the horizontal direction to be removed, the support shaft 20 cannot pass through the narrowest portion of the support shaft introduction space 26b and does not come off. However, when the second metal fitting 22b is raised, the support shaft 20 comes out of the inside of the rotation hole 25b, so that it can be easily removed. Therefore, the first metal member 21b of the first kind of rotation support metal member 9a is placed above the game board storage frame 8 by the second metal member 22b.
Is mounted above the back mechanism board 10, and the above-mentioned second kind of rotation support fitting 9 b is attached below the game board storage frame 8 and below the back mechanism board 10. Since the first metal member 21b and the second metal member 22b of the rotation support metal member 9a according to the present embodiment can be connected after connecting the frame-side metal member 32 and the mechanical panel-side metal member 36, the back mechanism disk 10 can be connected to the game board. It can be easily connected to the storage frame 8. That is, in this embodiment, the second fitting 22b as the second opening / closing tool of the hinge mechanism is used.
Is arranged so that the width of a portion (communication region) communicating with the rotation hole 25b of the support shaft introduction space 26b is slightly smaller than the diameter of the support shaft 20. By setting, the communication area can be changed from the normal state to the introduction state. In addition, as shown in FIG. 10, the second metal fitting 22b may be integrally formed of an elastic metal or the like, and may be attached while being reinforced by the reinforcing plate 41 '. A third embodiment of the first type of rotation support fitting 9a as a hinge mechanism provided in the gaming machine according to the present invention shown in FIGS. 11 to 14 is a vertical fastening similar to the above embodiment. A substantially horizontal support piece 19 is formed at the lower end edge of the piece 18, and the support piece 19 has a support shaft 20.
The first metal fitting 21c is provided as a first opening / closing tool having an upwardly erected top, and a second metal fitting 22c as a second opening / closing tool capable of fitting the support shaft 20 of the first metal fitting 21c. The second metal fitting 22c forms an inclined side 26c 'which becomes a part of a notch-shaped support shaft introduction space 26c from the side at a tip end portion of a main body 43 having a horizontal gap 42 disposed therebetween. At the tip of the side 26c ', an arc-shaped portion which is a part of a rotation hole 25c which can pass through the support shaft 20 is formed, and a guide groove 44 is formed in the upper surface portion of the main body 43 in the length direction.
At the tip, a plate-like slide member 45 is movably interposed between the inclined side 26c "which is a part of the support shaft introduction space 26c and an arc-shaped part which is a part of the rotation hole 25c. One end of 46 is guide groove 4
4 is connected to the protrusion 47 of the slide member 45 protruding from the main body 43.
The slide member 45 is urged toward the distal end of the main body 43 by being connected to the projection 48 on the upper surface of the main body 43, and a bracket 49 is fixed to the side of the main body 43 with screws or the like. When the rear ends of the bracket 49 and the main body 43 are fitted into the storage space 50 of the back mechanism panel 10 and the ends of screws passed through the abutment plate 51 are screwed into female screws of the bracket 49, the second metal fitting 22c is moved to the back mechanism. The main body 43 can be attached to the side of the board 10 in a state where the front end of the main body 43 projects. In a normal state, the second metal fitting 22c includes a
The projection 47 abuts on one end of the guide groove 44 of the main body 43 and stops. Therefore, a support shaft introduction space 26c gradually narrowing from the outer opening wider than the diameter of the support shaft 20 is formed at the side edge of the distal end portion of the main body 43, and the support shaft introduction space 26c is rotated by the support shaft introduction space 26c. The hole 25c is formed, and the width of a portion (communication region) connecting the support shaft introduction space 26c and the rotation hole 25c is slightly smaller than the diameter of the support shaft 20. The outer opening of the support shaft introduction space 26c of the second metal fitting 22c faces the side of the support shaft 20 of the first metal fitting 21c, and the outer opening of the support shaft introduction space 26c is formed by the first metal fitting 21.
When the second metal fitting 22c is advanced toward the game board storage frame 8 side in this state, the support shaft 20 enters the outside opening of the support shaft introduction empty space 26c, and When the second metal fitting 22c is pressed forward, the support shaft 20 presses the inclined side 26c ″ of the slide member 45, so that the slide member 45 retreats against the bias of the spring 46, and the support shaft introduction empty space 26c When the width increases (the communication area changes to the introduced state), and the second bracket 22c is further pressed forward to move the support shaft 20 to the depth of the support shaft introduction space 26c, the support shaft 20 is expanded. Shaft introduction empty space 26c
Through the narrowest part of the rotary hole 25c. When the support shaft 20 is fitted into the rotation hole 25c, the slide member 45 moves forward by the bias of the spring 46, and the support shaft introduction space 2
The width of 6c is returned to the original narrow initial state (normal state). Therefore, in this state, the second
Even if the metal fitting 22c is retracted in the horizontal direction and is to be removed, the support shaft 20 cannot pass through the narrowest part of the support shaft introduction space 26c and does not come off. However, when the second metal fitting 22c is raised, the support shaft 20 comes out of the rotation hole 25c, so that it can be easily removed. Therefore, the first metal fitting 21c of the first kind of rotation support metal fitting 9a is mounted above the game board storage frame 8, and the second metal fitting 22c is mounted above the back mechanism board 10. When the above-mentioned second kind of rotation support fitting 9b is attached below the mechanism board 10, the frame side fitting 32 and the mechanism board side fitting 3 of the second kind of rotation support fitting 9b are attached.

That is, in this embodiment, the second fitting 22c as the second opening / closing tool of the hinge mechanism is used.
Is movable by a spring 46 so that the support shaft introduction cavity 2
Since the width of the portion (communication area) communicating with the rotation hole 25c of 6c can be changed between a normal state in which the diameter is smaller than the shaft diameter of the support shaft 20 and an introduction state in which the rotation shaft 20 can be introduced.
As compared with the case where the second fitting is formed using the elastic member as in each of the above-described embodiments,
The possibility of breakage of the hinge mechanism due to metal fatigue or the like is reduced. In each of the above-described embodiments, if the communication area where the support shaft introduction space 26 and the rotation hole 25 communicate with each other can be changed between the normal state and the introduction state by using the elasticity of the material or the bias of the spring 46. In short, the joining operation between the first opening / closing member and the second opening / closing member can be easily performed. Can be considered. For example, the second type of rotation support fitting 9a shown in FIG. 15 has a substantially horizontal support piece 19 formed at the lower end edge of the vertical fastening piece 18 in the same manner as in the above-described embodiment. A first metal fitting 21d with the support shaft 20 standing upright and a second metal fitting to the support shaft 20 of the first metal fitting 21d.
22d. The second metal fitting 22d forms an outer opening wider than the diameter of the support shaft 20 at a side edge of a tip portion of the arm piece 52 extending substantially in the horizontal direction, and extends in the width direction of the arm piece 52 from the outer opening. A part of the support shaft introduction space 26d slightly wider than the diameter of the support shaft 20 is formed on the support shaft introduction space 26d.
Is formed from the tip of this portion to the side edge side of the arm piece 52 on the support shaft introduction space 26d.
Is formed in a bent shape, and a rotation hole 25d through which the support shaft 20 passes is opened at the tip of this portion. That is, when the hinge mechanism is constituted by the first fitting 21d and the second fitting 22d as described above, the support shaft 20 in the normal state introduced into the rotation hole 25d is bent by bending the middle of the support shaft introduction space 26d. Makes it difficult for the support shaft 20 to pass through the support shaft introduction empty space 26d in the reverse direction, and keep the state in which the support shaft 20 is fitted into the rotation hole 25d. However, in such a hinge mechanism, since the rotation hole 25d does not fit to the rotation shaft 20, rattling tends to occur, and it is suitable for supporting an open / close body having various heavy game function devices. Absent. In other words, in each of the above-described embodiments of the present invention, not only the operation of attaching the opening / closing body and the support member is easily performed, but also the opening / closing operation after the attachment can be performed stably, and the stability of the attachment state can be improved. Is also high. In each of the above-described embodiments, the first type of rotation support fitting 9a (a hinge mechanism including a first opening / closing tool and a second opening / closing tool), which can be attached with one touch, is placed upward, and the same type of conventional fitting is used. Although the description has been given of the case in which the two types of rotation support fittings 9b are attached below, the present invention may be any type in which at least one of the rotation support fittings is a first type rotation support fitting 9a that can be attached with one touch. The first type of rotation support metal 9a may be attached below and the second type of rotation support metal 9b may be installed above, or both may be the first type of rotation support metal 9a. <Effect of the Invention> As described above, according to the present invention, it is possible to introduce the rotating shaft of the first opening / closing tool into the communication area that connects the rotating shaft introduction cavity and the rotating hole in the second opening / closing tool. In this state, the rotating shaft can be fitted into the rotating hole from the side of the second horizontal plate. Does not come off from the turning hole, the turning shaft is rotatably held in the turning hole. Therefore, according to the gaming machine having the hinge mechanism including the first opening / closing device and the second opening / closing device, in the operation of attaching / detaching the opening / closing body to / from the support during the production of the gaming machine or the maintenance of the gaming machine. It is possible to easily lift the open / close body, which tends to be heavy because it has various game function devices, to easily fit the rotating shaft into the rotating hole or remove the rotating shaft from the rotating hole. Even when the hinge mechanism is provided at a plurality of positions, the pivot shaft and the pivot hole are required to be fitted simultaneously with the pivot shafts of all the first and second opening / closing members. Since it is not necessary to perform position adjustment with a skilled technique, the work of attaching the opening / closing body to the support can be performed extremely easily, and a gaming machine capable of improving work efficiency during manufacturing, maintenance and repair work, etc. Can be.
