Description

  The present invention relates to a ball game machine including a game board having a game area in which a pachinko ball such as a pachinko, an arrangement ball, and a sparrow ball rolls, and more specifically, a bullet configured so that the game board can be replaced from the front side. The present invention relates to a locking device for a ball game machine.

  Generally, in a pachinko gaming machine, a main body frame (also referred to as a front frame or a gaming machine main body) is pivotally supported on one side edge of a rectangular frame-like machine frame so that a game ball can roll on the main body frame. A cylinder lock in which a game board having a game area is fixed, a transparent plate holding frame (also referred to as a glass frame) is pivotally supported on one side edge of the main body frame so as to be openable and closable, and exposed on the front side of the main body frame By inserting a specific key into the key hole of the key and rotating the cylinder lock in one direction, the transparent plate holding frame is unlocked and the transparent plate holding frame can be opened and closed forward. The main body frame is unlocked by rotating the main body frame so that the main body frame can be opened and closed forward.

In recent years, pachinko machines are becoming mainstream in which a gaming board and a gaming control board attached to the gaming board can be exchanged from the viewpoint of recycling and economy. Accordingly, the game board can be operated from the front side of the gaming machine, for example, as shown in FIGS. By providing a game board mounting member (clamp device), the structure is changed so that the game board can be attached to and detached from the front side of the game machine and the game board can be easily replaced.
Furthermore, as a recent trend, pachinko gaming machines (enclosed gaming machines) that circulate gaming balls in one gaming machine without releasing any gaming balls to the outside of the gaming machines have been reviewed. In other words, this system does not require a ball circulation facility on the island, and it is easy to install in a game arcade, so such a gaming machine is expected to become popular in the future. Then, it is expected that the game board and the transparent plate holding frame can be exchanged as one set, so that the installation in the game hall and the renewal of the gaming machine are further facilitated.

In this engaged state, the pressing portions 77a and 77b of the game board push-out mechanisms 75a and 75b are opposed to the back surface of the game board 20.

As shown in FIG. 1, when the transparent plate holding frame 14 is closed, the engagement pieces 55a and 55b are engaged with the engagement portions 32a and 32b, and the engagement state is brought about by the elasticity of the springs 51a and 58b. Retained. Hereinafter, this engagement mechanism is referred to as a first engagement mechanism. At the same time as the operation of the first engagement mechanism, the engagement pieces 37 a and 37 b are engaged with the engagement portions 20 a and 20 b, and the engagement state is maintained by the elasticity of the spring 38. For this reason, in this structure, the transparent plate holding frame 14 is engaged not only with the locking device 40 provided in the main body frame 6 but also with the game board 20, and a double locked state is achieved. Therefore, it is possible to prevent the transparent plate holding frame 14 from being opened for illegal purposes.
Further, hook-like engagement pieces 65a, 65b are engaged with the engaging portions 20a, 20b from below, and hook-like engagement pieces 37a, 37b are provided to engage with the engagement parts 20a, 20b. Since 55a and 55b are engaged with the engaging portions 32a and 32b, the main body frame 6, the game board 20, and the transparent plate holding frame 14 are firmly connected to each other, and a robust lock state is realized. As a result, it is possible to prevent a member such as a wire for performing an unauthorized operation from being inserted into the gaming machine, thereby improving security.

For this reason, as shown in FIG. 2, the transparent plate holding frame 14 is opened, and a trouble such as a game ball clogged on the game board 20 is dealt with.

  Then, since the interlocking piece 72 is separated from the upright portion 35 by opening the transparent plate holding frame 14, in this state, the cylinder lock 12 is further rotated in the same direction as shown in FIG. 16, as shown in FIG. Thus, the operating rod 42 can be further moved up. That is, as shown in FIG. 6, the up / down movable range of the engagement / disengagement member 34 regulated by the lengths of the long holes 35a, 35b is set narrower than the up / down movable range of the operating rod 42. The cylinder lock 12 cannot be further rotated in the same direction unless the transparent plate holding frame 14 is opened. For this reason, when the cylinder lock 12 is further rotated in the same direction after the transparent plate holding frame 14 is opened, the projecting portions 70a and 70b are brought into contact with the upright portions 71a and 71b for the first time, and are pushed up as they are. When the combination mechanism is activated and the engagement pieces 65a and 65b are moved downward, the engagement with the engagement portions 20a and 20b, that is, the engagement with the game board 20 is released. As described above, in the present invention, the operation restricting means that allows the cylinder lock to be further rotated only by opening the transparent plate holding frame is provided, and the second engagement mechanism disengages the first engagement mechanism. Since the operation of releasing the engagement cannot be performed unless the transparent plate holding frame 14 is opened by operating, it is possible to prevent the game board 20 from being disengaged accidentally at once by trying to open only the transparent plate holding frame 14. be able to. In addition, the vertically movable range of the engagement / disengagement member 34 is restricted by the length of the long holes 35 a, 35 b, and is also restricted by the stopper 33 a protruding from the mounting plate 33 hitting the engagement / disengagement member 34. .

  After the second engagement mechanism is disengaged, the cylinder lock 12 is further rotated in the same direction as shown in FIG. 18, and the operating rod 42 is further moved upward as shown in FIG. If it does, the game board extrusion mechanism will act | operate and the game board 20 will be extruded ahead. That is, as the operating rod 42 is further moved upward, the overhang portions 84a and 84b rotate the press fittings 75a and 75b so that the press portions 77a and 77b protrude forward, and the upper and lower sides of the back of the other side edge of the game board 20 The game board 20 is detached from the frame-like recessed portion on the front surface of the main body frame 6 by pressing the portion forward. Therefore, the game board 20 can be removed from the main body frame 6 by operating the knob 19 to move the support shaft 17 downward and pulling the support shaft 17 from the bearing portion 11a.
