Abstract

PURPOSE:To identify patterns by means of an optical photosensor while making the section between rotary drums gradually smaller by operating a counter when a drum-shaped rotary member is rotation-driven, and identifying the types of the displayed patterns with the use of the number of counts when the drum- shaped rotary member is stopped. CONSTITUTION:At the time of the rotation of rotary drums 11-13, photosensors 200 and 201 generate pulse outputs by the transit of light reflecting parts 10 and 11 through front surface positions. First, the photosensor 201 generates a detecting pulse at the position of a reference position reflecting part 11, outputs a resetting pulse from a resetting detecting circuit, resets a counter 22, next, the photosensor 200 generates the detecting pulse at the position of each counting reflecting part 10, outputs the counting pulse from a counting detecting circuit 20, and sends it to the counting input of the counter 22. Consequently, the contents of the counter 22 when the rotary drum is stopped correspond to the rotation angle of the rotary drum stopping position for the reference position on the rotary drum, and by the counted value of the counter 22, the types of the patterns displayed to the player are identified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a symbol identification device for a rotating drum type display device for a gaming machine that can be used in a gaming machine such as a pachinko gaming machine or a slot machine.

[Conventional technology]

Slot machines, or pachinko and coin gaming machines that incorporate a slot machine mechanism.

A prize is provided to the player when various symbols written on a plurality of rotating drums lZ form a specific combination, for example, when all symbols are arranged in the same pattern at a predetermined upper position where the drum rotation is stopped. Therefore, in the rotating drum type display device of such a gaming machine, a device is required to identify the type of symbol that is visually displayed to the player at the drum rotation stop position. For example, a device described in Japanese Patent Laid-Open No. 59-37966 is known.

In this conventional device, a plurality of light reflecting portions are provided on the end surface of the rotating drum along the circular line 1-, corresponding to the patterns on the circumference of the drum.

One of them is used as a light reflecting section for determining the reference position, and a reflective optical sensor for optically detecting these light reflecting sections is placed at a predetermined position on the end surface side of the rotating drum. When these light reflection parts pass in front of the reflection type optical sensor due to rotation, the detection pulses generated by the reflection Ipl optical sensor are transferred to the reference position generated by the reference position light reflection part;
It counts the pulse while resetting the °C counter, detects the rotation angle of the drum with respect to the base position based on the count number of the counter when the drum stops + h, and identifies the type of display pattern corresponding to the stopped position. be.

[Problem that the invention seeks to solve]

In the conventional device described in -L, an optical sensor for detecting the light reflecting portion is arranged at a predetermined position on the end surface side of the one-rotation drum. For this reason, for example, if the rotating drum is 3 (lid = t
! , in the case of a row arrangement, the optical sensor for the central rotating drum must be placed in a narrow gap between the rotating drums,
For this reason, there is a problem that it is difficult to arrange them, or if they are arranged, the distance between the rotating drums becomes too large.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a symbol identification device for a rotating drum type display device for a game machine, which allows symbol identification using an optical optical sensor to be performed as a lid while reducing the interval between rotating drums.

[Means and effects for solving the problem] The symbol discrimination device for a rotating drum-type display device for a game machine according to the present invention arranges a plurality of types of symbols along the circumferential surface of a drum-shaped rotating member,
The system is configured to display a symbol at a predetermined position when the drum-shaped rotating member is stopped as a display symbol to the player.

On the circumferential surface of the drum-shaped rotating member, an optically detectable reference part for position determination and a plurality of optically detectable counting parts for counting at predetermined intervals corresponding to the symbols along one circumference direction are provided. A reference detector for optically detecting the reference part and a count detector for optically detecting the counting part are arranged at predetermined positions on the outside of the radial circumferential surface of the drum-shaped rotating member. Furthermore, a counter is provided that counts the detection pulses from the count detector and is reset by the detection pulses from the reference detector, so that when the drum-shaped rotating member rotates HA, the counter is activated and the drum-shaped rotating member is activated. The type of display symbol is identified by the count number when the symbol is stopped.

With such a configuration, there is no need to arrange the photodetector in a narrow gap between the drum-shaped rotating members, so that the spacing between the drum-shaped rotating members can be reduced.
