At this time, the attracting body 114 rotates in the direction indicated by the arrow e around the pivot shaft 115 and retracts from the back side of the frame side joint portion 48 to the side. For this reason, the attracting body 114 does not interfere with the attachment / detachment of the game board 9 even though the attracting body 114 on the game board 9 side attracts the frame side joint portion 48 to the front side.

  As mentioned above, although each Example of this invention was explained in full detail, this invention is not limited to these Examples, A various change is possible in the range which does not deviate from the meaning of this invention. In the embodiment, the game board 9 is attached to and detached from the front side of the game board mounting frame 8 having an open front side. However, the game board mounting frame 8 is opened to the rear side, and the game board 9 is attached to the game board mounting frame 8. It is possible to implement the same in the same manner even if it is designed to be attached and detached from the rear side.

  In that case, since the frame side joint portion 48 is the front side and the panel side joint portion 47 is positioned on the rear side, the attracting means 74 draws the frame side joint portion 48 rearward toward the panel side joint portion 47 side. What is necessary is just to comprise.

  It is sufficient that the frame-side joint portion 48 protrudes into the game board mounting frame 8 and is fixed to the front frame 3. The attachment portions 95 and 96 for the front frame 3 are provided on two adjacent sides, or one side or You may provide in three sides and may provide in a perimeter. In short, when the frame-side joint portion 48 is attached to the front frame 3 so as to protrude into the game board mounting frame 8, the support strength on the protruding end side of the frame-side joint portion 48 is lowered, so that the protruding end side is brought into the drawing means 74. By doing so, the panel side joint portion 47 may be drawn. In the embodiment, the board side connectors 56 to 59 of the board side joint portion 47 are fixed and the frame side connectors 90 to 93 are in a floating state. However, the frame side connectors 90 to 93 are fixed and the board side connectors 56 to 59 are fixed. May be provided in a floating state.

  As long as the pulling means 74 pulls the frame side joint portion 48 to the panel side joint portion 47 in conjunction with the fixing operation of the lock means 73, the mechanism is not a problem. The amount of drawing of the frame side joint portion 48 by the drawing means 74 needs to be such that an excessive load is not applied to the attachment portions 95 and 96 of the frame side joint portion 48 at the time of drawing.

  Further, the abutting position where the attracting means 74 abuts on the frame side joint portion 48 may be substantially the entire frame side joint portion 48 including the protruding end projecting from the game board mounting frame 8, or may be in the vertical direction and / or the horizontal direction. Multiple locations may be used. For example, in the case of the pulling means 74 that brings the pressing portion 112 into contact with the frame side joint portion 48 and draws it, two pressing portions 112 are provided in the vertical direction on the swing arm 107 corresponding to the frame side joint portion 48 and the upper portion. When the upper side of the frame side joint part 48 is pressed by the side pressing part 112, the lower side pressing part 112 lowers the frame side joint part 48 so that the lower mounting part 96 is not detached or damaged by the reaction. You may make it press the side.

  Furthermore, a recess in which the pressing portion 112 is fitted may be formed on the back side of the frame side joint portion 48 at a position where the pressing portion 112 of the pulling means 74 abuts. Moreover, you may provide the receiving part reinforced with the rib etc. in the position which the press part 112 of the back side of the frame side joint part 48 contact | abuts, and protrudes in a gazette. In addition, the frame-side joint portion 48 may be provided with reinforcing ribs or the like in the up-down direction and the left-right direction so as not to be damaged even if the pressing portion 112 comes into contact with the back side. The present invention can be similarly implemented in various ball game machines other than pachinko machines.
