And a second contact surface 16 b that contacts the other surface of the contact portion 26. The second support portion 16 supports the contact portion 26 by sandwiching the contact portion 26 between the first contact surface 16a and the second contact surface 16b. By being supported in this way, the contact portion 26 is held by the game board in a posture in which one surface thereof faces the inner surface of the game board holding frame 2. As described above, the support structure of the first connection member 21 including the support portion 14 (the first support portion 15 and the second support portion 16) (particularly the support structure that supports the contact portion 26 from the back side of the third component member 12c). ) Is also used as a rib structure formed on the third component 12c as a part of the decorative frame 12. Thereby, the strength of the decorative frame 12 can be further increased by supporting the first support member 21.

  The second connection member 22 is provided on the game board holding frame 2 side. The second connection member 22 is provided on the game board holding frame 2 so as to face the first connection member 21. That is, the first connection member 22 is provided at the position of the game board holding frame 2 facing the first connection member 21. The second connection member 22 includes a ball contact portion 34 that elastically contacts the first connection member 21 and an attachment portion 35 that is attached to the game board holding frame 2. More specifically, the second connecting member 22 is formed by bending a sheet metal, and has a planar attachment portion 35 to be attached to the game board holding frame 2 and a front end of the sheet metal bent and extended from the attachment portion 35. It is provided with an elastic contact portion 34 that is formed by folding back in a letter shape and should be elastically contacted with the contact portion of the first connection member 21.

  The elastic contact portion 34 of the second connection member 22 is attached to the work board holding frame 2 via the attachment portion 35 in a posture extending toward the contact portion 26 of the first contact member 21. As shown in FIGS. 4 and 6, the elastic contact portion 34 of the second connecting member 22 is configured as a protruding portion that protrudes from the attachment portion 35 in a predetermined direction. The elastic contact portion 34 has a first protruding portion 37 protruding from the attachment portion 35 and a second protruding portion 38 protruding from the first protruding portion 37.

  The first projecting portion 37 projects from the mounting portion 35 with an inclination at a predetermined angle. The 1st protrusion part 37 is comprised by flat form. The 2nd protrusion part 38 is comprised by the circular arc shape. The convex surface of the circular arc of the second projecting portion 38 is in contact with the contact portion 26 of the first connecting member 21. The second connecting member 22 is in elastic contact with the first connecting member 21 by the elastic deformation of the first protruding portion 37 in a state where the second protruding portion 38 is in contact with the contact portion 26 of the first connecting member 21. .

  The attachment portion 35 of the second connection member 22 is configured in a substantially rectangular plate shape as shown in FIG. A plurality of through holes 35 a are formed in the attachment portion 35. The attachment portion 35 contacts the inner surface of the game board holding frame 2 facing the contact portion 26 of the first connection member 21 and is fixed at this position. Further, the attachment portion 35 is attached to a metal reinforcing member 18 provided in the game board holding frame 2. The reinforcing member 18 is an element constituting a part of the inner surface of the game board holding frame 2.

  More specifically, the reinforcing member 18 of the game board holding frame 2 is configured in a long shape. The reinforcing member 18 is grounded via a predetermined ground wire. The reinforcing member 18 includes a support portion 40 that supports the second connection member 22. The support part 40 has a plurality of screw holes 41 as shown in FIG. The second connection member 22 is reinforced by a through hole 35a formed in the attachment portion 35 of the second connection member 22 and the screw hole 41 of the support portion 40, and is reinforced by a bolt, a screw member, or other fixing member. It is fixed to the member 18.

  According to the gaming machine according to the present invention described above, the first connection member 21 is elastically contacted with the guide rail 11, and the second connection member 22 is elastically contacted with the first connection member 21. By connecting to the game board holding frame 2, the guide rail 11 and the game board holding frame 2 can be connected without using lead wires. The game ball guided by the guide rail 11 can be neutralized by grounding the metal reinforcing member 18 provided in the game board holding frame 2.

  Further, the first connecting member 21 is elastically contacted with the guide rail 11 and the second connecting member 22 is elastically contacted with the first connecting member 21, thereby connecting each part without using a separate connecting member. become able to. As a result, the connection work can be simplified, the assembly work of the gaming machine can be facilitated, and the manufacturing cost of the gaming machine can be reduced.

  Further, by supporting the first connecting member 21 by the support portion 14 of the decorative frame 12, it is not necessary to use a separate support portion 14 material. Therefore, the number of parts of the gaming machine can be reduced, and the manufacturing cost of the gaming machine can be reduced thereby.

  Further, the direction in which the elastic contact portion 24 of the first connecting member 21 contacts the guide rail 11 is a direction along the board surface of the game board 4 and is not a direction perpendicular to the board surface. Similarly, the direction in which the elastic contact portion 34 of the second connection member 22 contacts the contact portion 26 of the first connection member 21 is a direction along the board surface of the game board 4 and is not a direction perpendicular to the board surface. Accordingly, the elasticity of the elastic contact portion 24 of the first connection member 21 and the elastic contact portion 34 of the second connection member 22 changes due to component variations at the time of delivery of the first connection member 21 and the second connection member 22, deterioration over time, and the like. Even so, the relative position of the game board 4 with respect to the game board holding frame 2 only needs to change in the horizontal direction. That is, the distance between the window portion that greatly affects the behavior of the game ball falling on the board surface of the game board 4 and the board surface of the game board 4 does not change, and this distance can be maintained constant.

  In addition, this invention is not limited to said embodiment, A various change and deformation | transformation are possible.

  For example, in the above-described embodiment, the example in which the connection unit 5 is configured by the two members of the first connection member 21 and the second connection member 22 has been described. By forming the attachment portion 35 on the first connection member 21, the guide rail 11 and the reinforcing member 18 of the game board holding frame 2 can be electrically connected only by the first connection member 21.

  Further, depending on the configuration of the gaming machine, for example, a third connection member may be interposed between the first connection member 21 and the second connection member 22. That is, the connecting means 5 may be constituted by three or more connecting members.

  In the above embodiment, the example in which the second connecting member 22 of the connecting means 5 is connected to the metal reinforcing member 18 provided in the game board holding frame 2 is shown, but the present invention is not limited thereto, and the game board holding frame 2 is not limited thereto. Alternatively, another metal member may be provided, and the member and the second connecting member 22 may be electrically connected.
