JP-A-6-47157 (page 4-5, FIG. 2, FIG. 3, FIG. 4)

  However, in the pachinko machine disclosed in Patent Document 1, the hook members provided on the upper right and lower parts of the front edge of the front frame are always biased and tilted to the game board side by a spring when the game board is not mounted. Therefore, when the game board is mounted, the hook members must always be tilted outward by hand so as not to interfere with the game board. For this reason, not only are the hands supporting the game board neglected and the game board is difficult to install, but the work is troublesome due to the extra effort. In addition, the pair of upper and lower hook members have a flat hook shape, so there is a high possibility of bending or breakage, and in such a state, the game board attached to the front frame rattles, There is a problem that not only can it be fixed firmly, but it can be a factor that makes the ball flying state unstable, for example.

  Therefore, the present invention has been made in view of the above problems, and it is possible to mount the game board by simply pushing it in without any extra effort, so that the assembly work can be easily performed, and the game board is firmly fixed without rattling. Accordingly, it is an object of the present invention to provide a ball game machine that can ensure a stable ball flying state.

  In order to achieve such an object, the ball game machine according to the present invention is a ball game machine in which a housing recess is formed on the front side of the gaming machine main body so that the game board can be detachably mounted from the front side. An insertion portion provided at one side edge of the recess and into which one side end portion of the game board is inserted; and a rotation mechanism portion provided at the other side edge of the accommodation recess and fixing the other side end portion of the game board; The rotation mechanism section includes an operation member that can be operated from the front side of the gaming machine main body side, a tilting position that rotates up and down by the operation of the operation member and faces the game board, and a vertical position that fixes the game board. And a fitting member that can be stopped and held.

  In addition, a pair of connecting members that are opposed to each other and can be electrically connected or disconnected in accordance with the attaching / detaching operation of the gaming board are disposed on the back side of the gaming board and the front surface of the gaming machine main body side, and at least one of them One connecting member is preferably provided so as to be movable within a plane orthogonal to the connecting direction.

  In the invention according to claim 1, the game board is fixed to the tilting position where the fitting member rotates in the vertical direction by the operation of the operation member which can be operated from the front side of the gaming machine main body and receives the game board. Since it can be stopped and held at the vertical position, the fitting member automatically fits to the side end of the game board only by pushing the game board into the housing recess, and the game board is fixed, Easy assembly work. In addition, the game board is firmly fixed, and there is an effect that a stable ball flying state can be secured.

  Further, as in the ball and ball game machine according to claim 2, the game board is placed on the back side of the game board and the front side of the game machine main body so as to face each other and is electrically connected or disconnected as the game board is attached or detached. If a pair of obtained connecting members are arranged and at least one of the connecting members is provided so as to be movable in a plane perpendicular to the connecting direction, both connecting members are automatically connected simultaneously with the mounting of the game board. As a result, the conventional wiring connection work when the game board is mounted becomes unnecessary. As a result, for example, there has been an effect that the work efficiency in assembling the pachinko machine is remarkably improved, as well as forgetting to forget to insert the connector, which has occurred in the past.

The other side of the game board 4 is fixed to the other side edge, that is, the upper and lower parts on the right side of FIG. A moving mechanism 27 is disposed. In addition, an output side connector 28 as a connecting member is disposed at a predetermined position of the frame plate 22 on the same side as this and is opposed to the input side connectors 19, and is also opposed to the positioning holes 20. Thus, the positioning pin 29 is arranged. Although a floating connector is used as the connector 28, a floating connector may be used for the connector 19 on the game board 4 side, or a floating connector may be used for both the connectors 19 and 28. The floating connector is provided so as to be movable in a plane orthogonal to the connection direction so that the connection can be performed safely and reliably. When the game board 4 is shifted up and down or left and right In addition, both connectors 19 and 28 can be reliably connected. Although not shown, the connector 28 is also electrically connected to the control board mounted on the back side of the front frame 3 by wiring.

  As shown in FIG. 4, each of the insertion portions 26 is provided at the front end portion of the inner surface of the side edge of the housing recess 21 and receives the front surface of the game board 4, and the base end portion is fixed to the step portion 25. The front end side is formed of a spring plate 31 that extends substantially horizontally toward the center and that pushes the game board 4 forward from the back side. The distance between the contact portion 30 and the step portion 25 is set to be slightly wider than the thickness of the game board 4.

  Since each said rotation mechanism part 27 is arrange | positioned so that it may become vertically symmetrical, the upper rotation mechanism part 27 is demonstrated for convenience. The rotating mechanism 27 is made of a metal member having a U-shaped cross section, and is fitted to the fixing member 32a fixed to the front surface of the front frame 3 and the upper end of the game board 4 as shown in FIG. It is comprised from the fitting member 32b to match | combine, and the operation member 32c which act | operates this fitting member 32b.

More specifically, the fixing member 32a has a pair of parallel side plates 33 projecting forward, and link plates 34 are pivotally supported by the horizontal fixed shafts 35 on both sides of the upper portion and at the lower portion. The fitting member 32b is pivotally supported by a fixed shaft 36 at its center and is freely rotatable in the vertical direction. The fitting member 32b is formed in a gate shape with a front leg 37a and a rear leg 37b that overlap each other at substantially the center, and is loosely fitted with an inner diameter larger than the outer diameter of the fixed shaft 36 at the overlapping part. A shaft hole 38 is formed.
The front end surface 37c of the rear leg 37b is formed into an arc surface protruding forward. This is because the front end surface 37c receives the rear surface of the game board 4 so that the operation of the fitting member 32b can be performed smoothly.

  The link plates 34 are pivotally supported by movable shafts 39 on both sides of the central portion of the operating member 32c, and the movable shafts 40 are disposed on both sides of the front portion of the front and rear legs 37a and 37b of the fitting member 32b. It is supported by. Further, a spring bar 41 is wound around the movable shaft 40 on both sides of the front portion, and one end 41a thereof abuts on the upper surface of the fixed shaft 36 that pivotally supports the fixed member 32a and the front and rear legs 37a and 37b. The other end 41b is in contact with the front surface of the front support plate portion 42 of the front leg 37a. Then, the front leg 37a abuts against the front surface of the game board 4 around the movable shaft 40 that pivotally supports the operation member 32c, and is elastically biased so as to always push the game board 4 backward. This is to suppress backlash before and after the game board 4 with the game board 4 mounted.

It is stopped and held at a tilting position where it contacts the game board 4 and faces the game board 4. On the other hand, when the operation member 32c is rotated upward, the fitting member 32b is rotated downward about the fixed shaft 36 and is stopped and held in the vertical position. Incidentally, when the game board 4 is actually pushed, the fitting member 32b whose upper end or lower end is positioned above and below is rotated downward or upward, and each operation member 32c is also fixed to the fixing member 32a. Rotate to the side to maintain a vertical posture. At this time, the upper end of the game board 4 is fitted between the front leg 37a and the rear leg 37b, and the game board 4 is fixed.

  The pachinko machine P according to the present invention has the above-described configuration. Next, a method for mounting the game board 4 will be described. The transparent plate holding frame 5 is opened, and the lower end of the game board 4 is placed on the upper surface of the shelf receiving part 24 of the housing recess 21 in a state where the fitting member 32b of each rotation mechanism part 27 is stopped and held at the tilting position where the game board 4 faces the game board 4. Put the part. Then, with the game board 4 arranged on the front side of the front frame 3, the left end portion toward the game board 4 is inserted into each insertion part 26 from the side. Furthermore, the upper and lower portions of the right end portion are pushed into the housing recess 21 toward the game board 4.

  Thereby, on the left side of the game board 4, as shown in FIGS. 6 (a) and 6 (b), the front surface of the game board 4 hits each abutment portion 30, and at the same time, the rear surface of the game board 4 is pressed forward by the spring plates 31. . Further, on the right side of the game board 4, as shown in FIGS. 7 (a) and 7 (b), the upper and lower end portions push the front end surface 37c of the rear leg 37b of each fitting member 32b backward. Accordingly, along with this, the front leg 37a is rotated downward, and the rear leg 37b is rotated upward, so that both fitting members 32b are fitted to the upper and lower end portions of the game board 4. In this state, the game board 4 is firmly fixed and does not rattle. In this way, simply by pushing the game board 4 into the housing recess 21, each fitting member 32 b automatically fits into the upper and lower ends of the game board 4 to fix the game board 4. Assembly work can be performed.

  When the game board 4 is housed in the housing recess 21, the positioning pins 29 are inserted into the positioning holes 20 as shown in FIGS. Will be. This prevents the game board 4 from moving unnecessarily in the front-rear and left-right directions, together with the insertion parts 26 and the rotation mechanism parts 27.

  Further, as shown in FIGS. 9A and 9B, the connector 19 on the back side of the game board 4 and the connector 28 on the front surface of the front frame 3 are electrically connected to each other at the same time. At the same time, since it can be performed automatically, the troublesome wiring connection work at the time of mounting the game board as in the prior art becomes unnecessary.

  In order to remove the mounted game board 4, if the operation member 32 c in each of the upper and lower rotation mechanism portions 27 is rotated forward, the upper fitting member 32 b is rotated upward and the lower portion as described above. The fitting member 32b is turned downward and the game board 4 can be removed forward. When each fitting member 32b rotates, each rear leg 37b abuts on the back surface of the game board 4 and pushes it forward, so that the connector 19 on the game board 4 side and the connector on the front frame 3 side are operated. 28 is automatically released, and the game board 4 can be easily removed from the front side. Thereby, the removal operation | work of the game board 4 can be performed easily.
