As shown in FIG. 5, the rotation engagement lever 69 is rotatably supported on the game board holding frame 90 by a screw 121 that passes through the center of the rotation engagement lever 69. Then, the rotation engagement lever 69 is set to the non-holding position (the state indicated by the broken line in FIG. 7) and the game board 11 is fitted inside the surrounding wall 93 of the game board holding frame, and then the holding position (solid line in FIG. ), A part of the lower side portion of the game board 11 is held between the game board holding frame 90 by the rotation engagement lever 69. In other words, the game board 11 is held by the game board holding frame 90 so as not to be detached by pressing a part of the game board 11 with the rotation engagement lever 69.

  As shown in an enlarged view in FIG. 6, the rotation engagement lever 69 is provided with a knob portion 116 standing up from the disc portion 115, and a through hole 119 is formed in the center portion. As shown in FIG. 10, the back surface side of the rotation engagement lever 69 in the through hole 119 forms a large diameter portion 119A, and the front surface side of the rotation engagement lever 69 tapers toward the large diameter portion 119A. The small-diameter portion 119B has a structure. Then, a cylindrical body 130 (see FIG. 5) standing up from the game board holding frame 90 is fitted inside the large diameter portion 119A, and a screw 121 passed from the small diameter portion 119B side is formed in the central portion of the cylindrical body 130. It is screwed into the formed screw hole. A slippery resin washer 122 is sandwiched between the head of the screw 121 and the rotation engagement lever 69. The resin washer 122 is disposed in the small diameter portion 119B so that the screw 121 is a cylinder. Screwed onto the body 130. Here, the cylindrical body 130 corresponds to the “shaft portion” of the present invention.

  The knob 116 has a wall shape, is orthogonal to the cylindrical body 130, and extends in the diameter direction of the disk portion 115. Of the knob 116, the lower end 116 </ b> B in FIG. 6 protrudes outward from the outer peripheral edge of the disc 115. Further, a protrusion 106 is formed on the surface of the protruding lower end portion 116B facing the game board holding frame 90. Note that both side surfaces of the knob portion 116 have an uneven shape, and serve as a slip stopper when an operator picks and operates the knob portion 116.

  In the knob portion 116, the portion above the through hole 119 in FIG. 6 has a stepped shape. A pressing piece 124 (corresponding to the “game board pressing portion” of the present invention) for pressing the game board 11 against the game board holding frame 90 is formed at the upper end of the knob portion 116. The holding piece 124 protrudes from the upper end surface of the knob portion 116 to the outside of the disc portion 115.

  An interference convex portion 125 is formed so as to protrude from a portion of the knob portion 116 where the pressing piece 124 is formed. In detail, the interference convex part 125 protrudes toward the back mechanism set board 75 side (side away from the disk part 115) from the surface on the side facing the back mechanism set board 75 of the knob 116, and as a whole. It has a block shape.

  A protrusion 107 that abuts against the rear surface of the game board 11 is formed on the surface of the holding piece 124 that faces the game board 11 when the rotation engagement lever 69 is in the holding position. Thus, when the game board 11 is pressed by forming the protrusion 107 on the press piece 124 and reducing the contact portion between the game board 11 and the press piece 124, a part of the game board 11 and the press piece The frictional force with 124 can be kept small, and the rotary engagement lever 69 can be smoothly moved between the holding position and the non-holding position. Further, the inside of the knob portion 116 is a cavity, and the cavity is open to the back surface of the disk portion 115 (the surface facing the game board holding frame 90).

  Here, in the game board holding frame 90, the attachment portion of the rotation engagement lever 69 has the following configuration. As shown in FIG. 5, an arc wall 131 is formed upright around the above-described cylindrical body 130 in the game board holding frame 90 toward the rear side of the game board holding frame 90. As a result, a substantially circular space around the cylindrical body 130 is formed. The arc wall 131 is opened upward, and the pressing piece 124 of the rotation engagement lever 69 projects from the opening to the inside of the surrounding wall 93 to which the game board 11 is fitted (state of FIG. 2). It is configured.

  Further, as shown in FIG. 7, projecting portions 132 and 132 projecting from the rear surface of the game board holding frame 90 project at two locations along the inner peripheral surface of the arc wall 131. Specifically, the protrusions 132 are provided at approximately 60 ° intervals about the cylindrical body 130 at a position substantially directly below the cylindrical body 130 and a substantially right side position of the cylindrical body 130. Then, when the holding position (the state indicated by the solid line in FIG. 7) where the game board 11 is held by the game board holding frame 90 by the pressing piece 124 (more specifically, the protrusion 107) of the rotation engagement lever 69 is reached. The protrusion 132 provided substantially directly below the cylindrical body 130 abuts the lower end 116B of the rotation engagement lever 69. Thereby, the rotation engagement lever 69 is prevented from rotating in the clockwise direction in FIG. Further, when the rotation engagement lever 69 is rotated counterclockwise from the holding position, the lower end portion 116B of the rotation engagement lever 69 and the protrusion 132 provided at the substantially right side position of the cylindrical body 130 come into contact with each other. As a result, the rotation engagement lever 69 is prevented from rotating counterclockwise in FIG. That is, when the game board 11 is pressed and held by the game board holding frame 90 by the rotation engagement lever 69 (the rotation engagement lever 69 is set to the holding position), the rotation engagement lever 69 abuts on the protrusion 132. It is only necessary to rotate clockwise until it hits (until it can no longer rotate). When the game board 11 is held by the rotation engagement lever 69 (when the rotation engagement lever 69 is set to the non-holding position), the rotation is performed. The engagement lever 69 may be rotated counterclockwise until it comes into contact with the protrusion 132 (until it cannot rotate).

  By the way, when the back mechanism set board 75 is overlapped on the rear surface of the game board holding frame 90, the entire rotation engagement lever 69 is covered by the back mechanism set board 75. As shown in FIG. 8, a portion of the front surface 75F of the back mechanism set board 75 that faces the rotation engagement lever 69 when overlapped with the rear surface of the game board holding frame 90 has a protruding wall 140 (the present invention). (Corresponding to “receiving convex part”).

  As shown in FIG. 8, the protruding wall 140 is provided at a lower position of the game ball collection basket 78. As shown in an enlarged view in FIG. 9, the protruding wall 140 protrudes forward from the front surface 75 </ b> F of the back mechanism set board 75, that is, toward the rear surface side of the game board holding frame 90. Specifically, the projecting wall 140 extends vertically downward from the lower side portion 78U of the game ball collection basket 78 and extends downward while curving in an arc shape from the middle. And the lower end part of the protrusion wall 140 is connected with the horizontal rib 142 extended in the left-right direction of the back mechanism set board 75. As shown in FIG. Here, the arcuate portion of the projecting wall 140 is provided corresponding to the overall movement position of the interference convex portion 125 when the rotation engagement lever 69 is in a position other than the holding position, that is, in the non-holding position. It has been.

  As shown in FIGS. 8 and 9, a recess 144 (corresponding to the “interference protrusion storage space” of the present invention) is formed on the side of the protruding wall 140. In the recess 144, the upper and lower side walls are constituted by the lower side portion 78 U of the game ball collection basket 78 and the lateral rib 142, and the left and right side walls are constituted by one side wall of the upper tray discharge port 88 and the protruding wall 140.

  When the rotation engagement lever 69 is not in the holding position, that is, when the knob 116 of the rotation engagement lever 69 is in the non-holding position (position indicated by the broken line in FIG. 7) inclined with respect to the vertical direction. When the back mechanism set board 75 is overlapped on the rear surface of the game board holding frame 90, the interference convex part 125 formed on the rotation engaging lever 69 hits the arcuately curved part of the protruding wall 140 (state of FIG. 11). That is, the positional relationship between the back mechanism set board 75 and the game board holding frame 90 at this time corresponds to the “second position state” of the present invention.

  On the other hand, when the rotary engagement lever 69 is in the holding position, when the back mechanism set board 75 is overlapped on the rear surface of the game board holding frame 90, the knob 116 of the rotary engagement lever 69, more specifically, the knob. Interference convex part 125 formed in part 116 is stored in recess 144 (state of Drawing 10). That is, the positional relationship between the back mechanism set board 75 and the game board holding frame 90 at this time corresponds to the “first position state” of the present invention.

Next, the operation of this embodiment will be described.
When the game board 11, the back mechanism set board 75, and the game board holding frame 90 are assembled together, it is as follows. First, the game board 11 is fitted into the surrounding wall 93 from the rear side of the game board holding frame 90. At this time, the game board holding lever 114 and the back mechanism set board holding lever 77 are set in an upright state from the surrounding wall 93 in advance, and the rotation engaging lever 69 is arranged so that the pressing piece 124 does not protrude inside the surrounding wall 93. The non-holding position (the state indicated by the broken line in FIG. 7) is set.

  After the game board 11 is fitted inside the surrounding wall 93, the four game board holding levers 114 and the rotation engaging levers 69 provided on both sides of the game board holding frame 90 are rotated to operate the game board 11. Fix to the panel holding frame 90. In other words, the game board holding lever 114 is rotated by about 90 ° to be put in a locked state along the surrounding wall 93, and the game board 11 is pressed and held between the locking projection piece 114K and the game board holding frame 90. Further, the rotation engagement lever 69 is rotated in the clockwise direction in FIG. 7 to the holding position, and the game board 11 is pressed between the holding piece 124 (more specifically, the protrusion 107) and the game board holding frame 90. Hold it.

  After the game board 11 is fixed to the game board holding frame 90, the back mechanism set board 75 is attached. First, the hinge pin 73 provided in the back mechanism set board 75 is inserted into the hinge hole 87 provided in the game board holding frame 90. Next, the back mechanism set board 75 is rotated with respect to the game board holding frame 90 around the hinge pin 73, and the back mechanism set board 75 is overlapped on the rear surface of the game board holding frame 90. Then, the various control boards 49 to 52 attached to the rear surface of the game board 11 are arranged in the rectangular window 74 of the back mechanism set board 75, and provided in the rotation engagement lever 69 as shown in FIG. The interference convex portion 125 is accommodated in a recess 144 formed on the front side of the back mechanism set board 75. As a result, the front surface of the back mechanism set board 75 comes into contact with the peripheral end face of the surrounding wall 93 of the game board holding frame 90.

  Next, the stopper 67, the ny latch 68, and the back mechanism set panel holding lever 77 (a part of the “second engagement member” of the present invention) are operated to respectively provide the required portions, that is, the hook 67F and the locking hole 68C. By engaging the side end edge 68e with the rear surface 75R of the back mechanism set board 75 (a part of the “second engagement member” of the present invention), the back mechanism set board 75 is attached to the game board holding frame 90. Stop and fix.

  Specifically, since the back mechanism set board 75 and the game board holding frame 90 are in the “first position state” (the state of FIG. 10), the link member provided in the stopper 67 of the back mechanism set board 75. And the hook 67 provided in the game board holding frame 90 come into contact with each other, and the hook 67F inserted through the slit 76 of the back mechanism set board 75 and the link member of the stopper 67 can be locked. Then, when the stopper 67 is placed on the back mechanism set board 75 side, the lower part of the back mechanism set board 75 is fixed to the game board holding frame 90.

  When the back mechanism set board 75 and the game board holding frame 90 are in the first position state (the state shown in FIG. 10), the back mechanism set board holding lever 77 provided on the upper side of the game board holding frame 90 is used. Since the back surface (the surface facing the game board holding frame 90 side) can come into contact with the rear surface 75R of the back mechanism set board 75, the back mechanism set board holding lever 77 is rotated in the same manner as the game board holding lever 114. It becomes possible. Then, the back mechanism set board holding lever 77 is turned to place the locking protrusion 77K on the rear side of the back mechanism set board 75, and the back mechanism set board 75 and the game board 11 are held together to hold the game board. Position between the frame 90 (see FIG. 3). Thereby, the upper side part of the back mechanism set board 75 is fixed to the game board holding frame 90.

  Further, when the back mechanism set board 75 and the game board holding frame 90 are in the first position state (the state of FIG. 10), as shown in FIG. Since it becomes a position where it can come into contact with the inner peripheral edge 68e of the locking hole 68C of the board holding frame 90, the nai latch 68 is pushed into the locking hole 68C formed in the game board holding frame 90 and is pushed in. It penetrates and engages with the locking hole 68C. Thereby, the side opposite to the side on which the hinge pin 73 of the back mechanism set board 75 is provided is fixed to the game board holding frame 90. Here, when the rotation engagement lever 69 is set to the holding position, it is only necessary to rotate the lever 116 until the rotation engagement lever 69 stops by picking the knob 116, so that the operability of the rotation engagement lever 69 is improved. Since the rotation engagement lever 69 does not need to be aligned, the rotation engagement lever 69 can be set to the holding position easily and reliably.

  By the way, when the back mechanism set board 75 and the game board holding frame 90 are to be fixed in a state in which the game board 11 is not completely held by the rotation engagement lever 69, the following occurs. That is, the rotation engagement lever 69 rotates the back mechanism set board 75 with respect to the game board holding frame 90 while keeping the non-holding position where the game board 11 is not pressed and held by the game board holding frame 90, When the mechanism set board 75 is brought closer to the rear surface side of the game board holding frame 90, as shown in FIG. 11, the interference convex portion 125 projecting rearward from the pressing piece 124 of the rotation engagement lever 69 becomes the back mechanism set board 75. It contacts the front end surface of the projecting wall 140 projecting from the front surface. Then, compared with the case where the back mechanism set board 75 is attached to the game board holding frame 90 with the rotation engagement lever 69 as the holding position between the front surface of the back mechanism set board 75 and the rear surface of the game board holding frame 90. Thus, a large space S is formed, and the back mechanism set board 75 and the game board holding frame 90 (specifically, the surrounding wall 93) cannot be brought into contact with each other. That is, the back mechanism set board 75 and the game board holding frame 90 are in the “second position state”.

  In the “second position state”, since the hook 67F of the game board holding frame 90 is not inserted into the slit 76 of the back mechanism set board 75, the stopper 67 and the hook 67F cannot be brought into contact with each other and cannot be engaged. Become. Further, in the “second position state”, even if the back mechanism set panel holding lever 77 is turned from the non-locked state to the locked state, the back mechanism set panel holding lever 77 is moved in the middle. Since it collides with the upper side of the set board 75, the back mechanism set board holding lever 77 cannot be held by the back mechanism set board holding lever 77. Further, in the “second position state”, as shown in FIG. 11, the ny latch 68 cannot penetrate the locking hole 68C, so that the stepped surface 68d at the tip of the ny latch 68 and the game board holding frame 90 are engaged. The rear end edge 68e of the stop hole 68C cannot be contacted, and the back mechanism set board 75 and the game board holding frame 90 cannot be fixed by the ny latch 68. That is, it becomes impossible to prevent the back mechanism set board 75 from being rotated and fixed to the game board holding frame 90.

  As described above, according to the present embodiment, when the rotation engagement lever 69 is in the non-holding position where the game board 11 is not held, the interference convex portion 125 provided on the rotation engagement lever 69 and the back mechanism set board. Since the projecting wall 140 formed on 75 collides, the back mechanism set board 75 and the game board holding frame 90 are separated from each other and cannot contact each other. As a result, the ny latch 68 and the locking hole 68C, the stopper 67 and the hook 67F, and the back mechanism set board holding lever 77 and the back mechanism set board 75 cannot be engaged. That is, the game board 11 is not completely held by the rotation engagement lever 69, and the game board holding frame 90 and the back mechanism set board 75 are not fixed. Can be prevented.

  Further, since the protruding wall 140 is provided over the entire position (non-holding position) other than the holding position of the rotation engagement lever 69, only when the rotation engagement lever 69 is reliably in the holding position. The back mechanism set board 75 and the game board holding frame 90 can be engaged with each other. Thereby, the assembly | attachment defect of the game board 11 can be prevented more reliably.
