  Next, by fitting the game board 101 into the accommodating part 12a from the front side of the inner frame 12, the extending part 21a extending from the front right side of the game board 101 is fixed from the front side of the inner frame 12 to the fixing device 40a. , 40b. As shown in FIG. 10, since the clamp part 43 is held in the first state, the edge of the extension part 21 a is guided to the opening of the clamp part 43.

  When the game board 101 is further fitted into the accommodating portion 12a, the extending portion 21a comes into contact with the inside of the clamp portion 43 (first clamp member 43a). As a result, as shown in FIG. 11, the clamp part 43 is pressed by the extension part 21a, and the clamp part 43 has a U-shaped opening downward from the first state around the first connecting pin 50a ( It swings counterclockwise in FIG. On the other hand, the lever portion 45 connected to the clamp portion 43 also swings in a direction away from the clamp portion (clockwise direction in FIG. 11) about the third connection pin 50c. Further, the link portion 47 connected to the lever portion 45 by the fourth connection pin 50d also swings downward (counterclockwise in FIG. 11) about the second connection pin 50b.

  Then, when the game board 101 is completely fitted into the accommodating portion 12a of the inner frame 12 from the state of FIG. 11, the clamp portion 43 is parallel to the mounting surface of the inner frame 12 (see FIG. 8 and FIG. 12). In FIG. 12, the second state is directed downward.

  At this time, both side surfaces of the link portion 47 are inserted between both side surfaces of the base portion 41 by pressing the first knob portion 60 of the lever portion 45 toward the base portion 41 side. Then, when both side surfaces of the link portion 47 are press-fitted to a position where they overlap with the hemispherical second convex portion 67 protruding inside the both side surfaces of the base portion 41, a frictional force is generated, and the clamp portion 43 is brought into the second state. Retained. Further, since the stepped portion 65 of the link portion 47 abuts against the side edge of the lever portion 45, the lever portion 45 and the clamp portion 43 can be moved even when excessive force is applied to the first knob portion 60. It does not swing beyond the state of FIG.

  Similarly, the same operation is performed on the fixing device 40b provided on the lower right side of the inner frame 12, so that the clamp portion 43 of the fixing device 40b is also held in the second state. Finally, the work of attaching the gaming board 101 to the gaming machine frame 113 is completed by overlapping the glass door frame 13 on the inner frame 12 and fixing it.

  According to the configuration of the present embodiment, it is easy to introduce the extension portion 21a into the clamp portion 43 of the fixing devices 40a and 40b in advance only by operating the lever portion 45 when the gaming board 101 is attached to the gaming machine frame 113. The first state can be maintained. For example, in the assembly work of the gaming board 101 to the gaming machine frame 113 in the factory, the gaming board 101 is sequentially assembled to the gaming machine frame 113 that moves at a constant speed on the production line. At this time, the clamp portions 43 of the fixing devices 40a and 40b attached to the gaming machine frame 113 are set in the first state. Thereby, the extension part 21a of the game board 101 can be easily inserted into the clamp part 43 in a state where one operator holds the heavy game board 101 with both hands. Further, since the mechanism for holding the clamp portion 43 in the first state is provided, the clamp portion 43 of the fixing device 40a located above is moved to the first position by vibration when the gaming machine frame 113 moves on the production line. There is no risk of turning downward from the state. Note that, similarly to the above-described assembly work in the factory, the burden on the operator during the replacement work of the game board 101 in the pachinko hall can be reduced.

  Further, as a mechanism (first holding mechanism) for holding the clamp portion 43 in the first state, a hemispherical first convex portion 63 that protrudes outward on both side surfaces of the lever portion 45 is formed, and the first convex portion 63 is Since the clamp part 43 is held in the first state by the frictional force when it is press-fitted into a position overlapping the inner side surface of the clamp part 43, the first holding mechanism can be made simple.

  Here, the first convex portions 63 are formed on the outer sides of both side surfaces of the lever portion 45, but the first convex portions 63 may be formed only on one side surface. Moreover, the 1st convex part 63 can be replaced with the lever part 45, and can also be formed in the clamp part 43 (2nd clamp member 43b). In this case, the first convex portion 63 may be formed so as to protrude toward the inner side surface of the second clamp member 43b, and a frictional force may be generated between the outer side surface of the lever portion 45.

  On the other hand, the clamp part 43 can be held in the second state only by operating the lever part 45 after the game board 101 is attached. As a result, it is possible to prevent the game board 101 from being damaged by suppressing the play and vibration of the game board 101 due to vibrations and shocks during transportation, or the operation of the accessory after installation in the pachinko hall.

  Further, as a mechanism (second holding mechanism) for holding the clamp portion 43 in the second state, a hemispherical second convex portion 67 protruding inward on both side surfaces of the base portion 41 is formed, and the second convex portion 67 is formed. Since the clamp portion 43 is held in the second state by the frictional force when being pressed into a position overlapping the outer side surface of the link portion 47, the second holding mechanism can be made simple.

  In addition, although the 2nd convex part 67 was formed in the both sides inner surface of the base part 41 here, you may form the 2nd convex part 67 only in one side. Further, the second convex portion 67 can be formed on the link portion 47 instead of the base portion 41. In this case, the second convex portion 67 may be formed so as to protrude to the outside of the side surface of the link portion 47 so that a frictional force is generated between the inside of the side surface of the base portion 41.

  In addition, the fixing members 40 a and 40 b provided on one end side of the gaming machine frame 113 have a clamp portion 43 composed of a first clamp member 43 a and a second clamp member 43 b, and a plate spring 51 and the first clamp member 43 a. The second clamp members 43b are biased in a direction in which they approach each other. On the other hand, the holding part 31 provided on the other end side of the gaming machine frame 113 is configured by a rib 31a and a pressing piece 31b. Therefore, even when the game board 101 having a different thickness of the extending portion 21a is fitted into the gaming machine frame 113, the extending portion 21a can be securely held using the fixing members 40a and 40b and the holding portion 31.

  Further, when the clamp portion 43 is held in the first state (the state shown in FIG. 7), the second knob portion 61 provided on the clamp portion 43 is operated together with the first knob portion 60 of the lever portion 45. Thus, the first convex portion 63 of the lever portion 45 can be easily press-fitted into a position overlapping the inner side surface of the clamp portion 43. That is, the operation of holding the lever 45 in the first state can be performed more smoothly.

  In addition, since the fixing devices 40a and 40b are provided at two positions on the upper and lower sides of the inner frame 12, the upper and lower ends of the game board 101 can be firmly held, and can be used during transportation or after installation in a pachinko hall. The play of the game board 101 due to the operation of an object can be more effectively suppressed. Furthermore, since the fixing device 40b provided below the inner frame 12 is disposed in the vicinity of the connector connecting portion 30, the play of the game board 101 around the connector connecting portion 30 is suppressed, and the connector and the connector connecting portion. Connection failure with 30 can be prevented.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the above-described embodiment, the gaming machine frame 113 including the outer frame 11, the inner frame 12, and the glass door frame 13 has been described as an example. However, for example, the outer frame 11 and the inner frame 12 are integrated. It is also possible to use a gaming machine frame. Further, in the above embodiment, the fixing devices 40a and 40b are arranged at the upper right and lower right of the inner frame 12. However, there is no problem in the assembly workability of the game board 101 and the stability of the game board 101 after the assembly. It may be placed in the place. The number of fixing devices 40a and 40b is not limited to two, and may be three or more.

  Moreover, in the said embodiment, although the 1st convex part 63 and the 2nd convex part 67 were formed as the 1st holding mechanism and 2nd holding mechanism which hold | maintain the clamp part 43 in a 1st state and a 2nd state, lever The mechanism is not limited to the first convex portion 63 and the second convex portion 67 as long as the mechanism generates a frictional force between the portion 45 and the clamp portion 43 and between the base portion 41 and the link portion 47. For example, by making the width direction dimension of the lever portion 45 inserted between the both side surfaces of the second clamp member 43b into a tapered shape that gradually increases as insertion proceeds, the lever is formed without forming the first convex portion 63. A frictional force can be generated between the portion 45 and the clamp portion 43.

  Moreover, in the said embodiment, the clamp part 43 is comprised by the 1st clamp member 43a and the 2nd clamp member 43b, and the 1st clamp member 43a and the 2nd clamp member 43b are urged | biased by the leaf | plate spring 51 in the direction which mutually approaches. For example, the clamp portion 43 is integrally formed of a metal having a spring property (restorability), and when the gaming board 101 having a different thickness of the extension portion 21a is fitted into the gaming machine frame 113, the clamp portion 43 is It is good also as a structure which elastically deforms. Further, the shape of the clamp portion 43 is not limited to the U-shape in the side view as in the above-described embodiment. For example, the extension portion 21a of the game board 101 is sandwiched like the C-shape in the side view or the U-shape in the side view. Any shape is possible.

  Moreover, in the said embodiment, the 2nd knob part 61 is provided in the clamp part 43, and the 1st state and the 2nd state are operated by operating the 2nd knob part 61 with the 1st knob part 60 of the lever part 45. Although the switching is performed, the second knob 61 is not an essential component, and a configuration in which only the first knob 60 of the lever 45 is provided is also possible.
