Abstract

PURPOSE: To enable increase in the number of patterns per unit length of a pattern display belt by forming an endless pattern display belt in such a manner that only one of both end parts of a belt body is twisted once as a whole after turned inside out to be moved in circulation. CONSTITUTION: Three pattern display belts 5 which are so arranged to display patterns in variation are mounted side by side in parallel in a case body set behind a rectangular frame-shaped window frame fitted on a game board. Here, the pattern display belts 5 are each formed in an endless Mobius's belt by joining both ends of a belt body with guide rollers 8a and 8a in such a manner that one only of both ends of the belt body is twisted once as a whole after turned inside out. Then, a plurality of patterns 5a are arranged on both sides of each of the belts 5 at an equal interval along the length of the belt 5. Thus, when the belts are driven in circulation by a step motor 10 through a drive roller 6, the patterns 5a both on the surface and rear sides are displayed sequentially.

Description

Detailed Description of the Invention

[0001]

This invention relates to a pachinko machine,
The present invention relates to a symbol display device that mechanically variably displays symbols.

[0002]

2. Description of the Related Art A symbol display mechanism that mechanically variably displays a symbol using a rotating drum or a belt is known.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to increase the number of symbols per unit length of the symbol display belt in a symbol display device having a symbol display belt.

[0004]

A pattern display device in a pachinko machine according to the present invention is designed such that only one end of both ends of a strip having a predetermined length is turned over and the entire strip is twisted once. In this state, both ends of the strip are joined together to form a pattern display belt in which symbol groups are listed on both sides, and a drive mechanism for rotating the symbol display belt is provided.

[0005]

The endless shape is formed by joining both ends of the strip with the entire strip twisted once with only one end of the strip having a predetermined length turned inside out. When the symbol display belt is driven to rotate by the drive mechanism, the symbol groups listed on one side of the symbol display belt and the symbol groups listed on the opposite side of the symbol display belt are displayed in an alternating manner.

[0006]

According to the present invention, it is possible to display all the symbol groups listed on one side of the symbol display belt and the symbol groups listed on the opposite side of the symbol display belt. The number of symbols per unit length can be increased, and if the belt length is constant, the number of symbols that can be displayed can be doubled to display twice the number of symbols.
If the number of symbols to be displayed is fixed, the belt length can be shortened to 1/2 and the symbol display device can be downsized.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a first embodiment of the present invention will be described with reference to FIGS. In the pattern display device mounted on the game board 1 of the pachinko machine, the peripheral portion of the transparent or semitransparent display window 3 is provided in the rectangular frame-shaped window frame 2 fixed to the opening edge of the opening portion 1a of the game board 1. Are combined.

[0008] In the case body 4 which is connected to the window frame 2 and installed behind the window frame 2, three symbols are arranged side by side in the lateral direction and through the display window 3 so as to variably display the symbol group. Display belts 5 to 5 are loaded.

Each of the symbol display belts 5 has both ends of the flexible band body having a predetermined length, with only one end of the both ends of the flexible band body being turned over and the entire band body being twisted once. The parts are joined to form an endless Mobius strip.

On both sides of each symbol display belt 5, a plurality of symbols 5a arranged in the longitudinal direction at equal intervals are listed.

Each symbol display belt 5 has a driving roller 6 installed on the rear side near the upper end of the display window 3, a front guide roller 7 installed on the rear side near the lower end of the display window 3, and a drive roller 6. And a pair of upper and lower rear guide rollers 8 installed symmetrically in the vertical direction behind the front guide roller 7
It is installed in the rear of the display window 3 so as to circulate and rotate while being hung on A and 8B, respectively.

A twisting portion 5b running on each of the symbol display belts 5 while being twisted once between both rear guide rollers 8A and 8B.
And the rear guide rollers 8A and 8B are driven by the drive roller 6 so that the entire twisted portion 5b travels in a tensioned state.
Also, the front guide roller 7 and the rear guide rollers 8A and 8B are installed so as to be inclined with respect to the axis of the front guide roller 7 in the front-rear direction.

Each drive roller 6 is rotationally driven by a step motor 10 installed in a space surrounded by each symbol display belt 5, and each symbol display belt 5 is driven by each step motor 10 via each drive roller 6. It is circulated and driven individually.

At the front end of the symbol display belt 5, there is formed a straight traveling portion 5d which travels straight between the drive roller 6 and the front guide roller 7 on the rear side of the display window 3 in parallel with the game board surface. When circulates, each symbol on the front surface of the straight running portion 5d is sequentially displayed through the display window 3, and the symbol group listed on one side of the symbol display belt 5 and the symbol group listed on the opposite side. Alternately pass through the rear side of the display window 3, and all the symbols 5a respectively listed on both sides of the symbol display belt 5 are variably displayed through the display window 3.

Next, the operation and effect of the embodiment having the above-mentioned structure will be described. In this example, only one end of the both ends of the strip having a predetermined length is turned upside down and the entire end of the strip is twisted once, and both ends of the strip are joined to form a pattern. There are provided symbol display belts 5 in which groups are listed on both sides, and a drive mechanism for circulatingly rotating the symbol display belts 5.

Therefore, the symbol group listed on one side of the symbol display belt 5 and the symbol group listed on the opposite side of the symbol display belt 5 can all be displayed, so that the unit length of the symbol display belt 5 The number of symbols per hit can be increased, and if the belt length is fixed, the number of symbols that can be displayed can be doubled to display twice the number of symbols, and the number of symbols to be displayed can be kept constant. Then, the belt length can be reduced to ½ and the pattern display device can be downsized.

Next, the second embodiment of the present invention shown in FIG. 3 will be described. In this embodiment, the symbol display belt 5 is a rotary drum 11 fixed to the output shaft of the step motor 10, and the rear of the rotary drum 11.
