DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display for a gaming machine such as a pachinko machine or a slot machine.

[0002]

2. Description of the Related Art Conventionally, as a display device of a gaming machine such as a pachinko machine or a slot machine, a dot matrix display device using an LCD or an LED, a rotating drum type display device having a pattern printed on a peripheral surface, a leaf type display device, and the like are known. is there. Among them, the leaf display mechanism has the advantage that it is inexpensive compared to the dot matrix display element and can be made smaller than the rotary drum display mechanism.

[0003] A conventional leaf-type display mechanism, as described in, for example, Japanese Patent Publication No. 57-8623, has a plurality of display plates rotatably supported on the outer periphery of a rotating wheel having flanges at both ends. Are mounted in parallel on one rotating shaft so as to be able to rotate by friction contact. When the rotating shaft is rotated by the motor, each rotating wheel is rotated by frictional contact with the rotating shaft.

A stop mechanism is provided for each rotating wheel, and each of the stopping mechanisms swings a lever by a solenoid and locks the lever to a ratchet gear provided on a side surface of the rotating wheel. Thus, the rotation of the rotating wheel is forcibly stopped with respect to the rotating rotating shaft.

When the rotating vehicle is stopped, the upper display plate of the pair of upper and lower display plates constituting the display surface is locked at the display position by a stopper. Therefore, a pair of upper and lower display plates located at the display position are arranged in a plane, and one pattern is displayed as a pair of the upper and lower display plates.

[0006]

However, in a display device using a conventional leaf-type display mechanism, a ratchet gear rotating at high speed is securely locked at a predetermined position, and is retracted from the locked state at the time of starting. Operation is required, and a large-torque locking mechanism is indispensable for each rotating wheel, so that the overall size is large and the structure is complicated. In addition, since each rotating wheel rotates by frictional contact with the rotating shaft, the rotating operation is not reliable due to the occurrence of wear and slippage.

[0007] Further, since a large number of rotating wheels are driven by one motor, all parts are integrated.
Even when one of the rotating wheels or the ratchet gear is damaged, the whole must be disassembled, and there is a problem that replacement and installation of parts are very troublesome.

Further, in the structure of the conventional leaf-type gaming machine, when the upper leaf is locked at the display position by the stopper and the upper and lower leaves are vertically and planarly arranged, the upper leaf is engaged by the stopper. It will not stop and shake,
Since the lower leaf is in a free state, it swings back and forth at the moment when the rotating drum stops, and there is a problem that the player cannot clearly confirm the pattern.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has as its object to ensure the operation of a leaf-type display mechanism, to be small in size, to have a simple structure, and to make assembly and replacement of parts easy. It is an object of the present invention to provide a display device for a gaming machine which can be performed easily and the leaf does not swing when the rotating vehicle stops.

[0010]

According to the present invention, there is provided a rotary drum having a plurality of support holes formed on a flange portion of a cylindrical portion on the same circumference and at equal intervals, and the support of the rotary drum is provided. A display plate made of an elastic plate material supported on a hole and having a pattern extracted on both sides thereof; a motor such as a stepping motor having a boss fixed to the rotating shaft while being housed in the rotating drum; And a mounting plate for detachably mounting the mounting plate.

Therefore, while the rotating drum 21 is rotating, 1
You can see the two symbols appearing relatively long,
In addition, the display can be visually recognized as being instantaneously switched to the next pattern, and the display plate 22 becomes stable at the same time when the rotation drum 21 stops. The rotating drum of each display unit 11
The rotation speed of 21 may be constant or different.

When the user operates a stop button (not shown) or when a predetermined time elapses from the start of the operation, the stepping motors 13 of the display units 11 are stopped in order from the left to the center and the right.

In the control section for stopping each stepping motor 13, the stop position of the rotating drum 21 of each display unit 11, that is, the displayed picture can be grasped. Therefore, a predetermined arrangement such that the pictures of the three display units 11 match. Is determined, and the determination result is output to the control means of the pachinko machine 1.

As described above, the display device 3 includes the stepping motor 13 inside the rotary drum 21 of the leaf-type display mechanism 12.
The rotating drum 21 is rotated and stopped by the stepping motor 13, so that the operation of the leaf-type display mechanism 12 can be reliably performed, and the leaf-type display mechanism 12 can be reduced in size and simplified in structure. Further, by supplying a small hold current when the stepping motor 13 is stopped, the pattern can be reliably held at the stop position, and the pattern does not change even when vibration is applied.
