Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine design in which a pair of rotating bodies are axially supported by a support frame at intervals in the radial direction, and a design belt is wound around the pair of rotating bodies. Regarding mobile devices.

[0002]

2. Description of the Related Art The pattern moving device of the slot machine
Since the design belt is wound around a pair of rotating bodies that are axially supported at intervals, compared to a design moving device that rotates a cylindrical reel in which designs are arranged side by side in the circumferential direction, a fixed number of If you want to arrange the symbols side by side along the direction of rotation, there is an advantage that the thickness of the symbol moving device can be reduced to reduce the overall thickness of the slot machine. The bearing member of the rotating body is fixed to a fixed position of the support frame in a state in which the pattern belt is elastically stretched and deformed, and tension is applied to the pattern belt (see, for example, JP-A-3-162879). .

[0003]

According to the above-mentioned prior art, since the bearing members of the pair of rotating bodies are fixed at fixed positions of the frame, if the pattern belt creeps and deforms within a long period of time, the pattern belt concerned. However, there is a drawback that the bearing member needs to be fixed at a fixed position of the support frame, and thus it takes time and effort to assemble the rotary body to the support frame. The present invention has been made in view of the above circumstances, and by devising a mechanism for applying tension to the design belt, the design belt is unlikely to loosen for a long period of time, and the rotating body is assembled to the support frame. An object is to provide a pattern moving device of a slot machine that is easy to attach.

[0004]

The characteristic features of the present invention for achieving the above object are as follows. A pair of rotating bodies around which an endless belt-shaped design belt is wound, and a pair of supporting frames that separately support bearing members of the pair of rotating bodies are provided, and the pair of supporting frames rotate with each other. The pair of support frames is provided with a biasing mechanism that is relatively movable in the radial direction of the body and that biases the pair of rotating bodies in a direction in which the pair of rotating bodies are separated from each other in a state in which the pattern belt is wound. A symbol moving device of a slot machine provided over the whole area, wherein B. Engagement in which at least one of the support frames is engaged and locked in a radial direction in which a bearing member to be supported by the support frame is moved together with the rotating body in proximity to the rotating body supported by the other supporting frame. Section is provided,
A symbol moving device of a slot machine in which a bearing member engaged with the locking portion is held in a locked state by a biasing force of the biasing mechanism. The configuration of A and B described above provides the following operational effects from this configuration.

[0005]

With the construction of the above A, the pattern belt wound around the pair of rotating bodies is tensioned by the urging force of the urging mechanism, so that the pattern belt is hard to loosen for a long period of time. With the configuration of B, the bearing member is engaged with the rotating body in the locking portion, and the biasing force of the biasing mechanism is utilized to hold the bearing member in the locked state by the biasing force. It is easier to assemble the rotating body to the support frame as compared with the case of fixing to the support frame.

[0006]

As a result, the pattern belt is not easily loosened for a long period of time, and the rotating body is easily assembled to the support frame.
