Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine capable of displaying various patterns, characters and the like on a display device. 2. Description of the Related Art As is well known, a pachinko machine is provided with many display devices for visually displaying a game state to a player and for decoration. As a conventional display device, for example, there is a so-called digital display that displays a number or an English character as a display mode by a combination of light-emitting portions of a seven-segment light-emitting diode, and draws a plurality of patterns or characters on the outer surface of a rotating drum. There is a rotary drum display or the like in which one of the symbols or the like faces the display window and the display mode of the symbols or the like is changed by the rotation of the drum. Further, for example, 5 × 7 light-emitting diodes are arranged as display elements vertically and horizontally,
There is a matrix display for selecting and displaying a light emitting portion.
In addition, there is a digital display, a rotating drum display, or a plurality of matrix displays which are connected in series to combine each display. [0003] In the conventional display device, the display mode of display is controlled by a control device having a microcomputer. However, the conventional control device controls the display element of the display device, and also has a pachinko machine such as a continuation switch, a 10-count switch, a start-up switch, a drive solenoid, or a sound effect or an indicator light provided in a center accessory or the like. It is necessary to perform overall control, the working capacity of the microcomputer is approaching its limit, and it has been impossible to display complicated display modes and execute high-speed processing. In addition, when the control is performed by one control device including the display device, the control device becomes large in size, the handling becomes troublesome, the wiring becomes complicated, and the complicated wiring hinders other components. In addition, in pachinko machines, since the center accessory generally protrudes rearward, when the size of the control device is increased, the degree of freedom of the mounting space is reduced and mounting is difficult. Further, even if a failure or change occurs in a portion related to control of the display device, the entire control device must be replaced. On the other hand, when a failure or change occurs in a portion related to game control, the portion including the display device must be replaced. Therefore, there is much waste and the cost is high. In addition, when replacing a large-sized control device, accidents such as damage to other electronic components or disconnection are likely to occur, and disconnection and connection of wiring accompanying the replacement work are complicated. SUMMARY OF THE INVENTION The present invention has been proposed in view of the above, and has been proposed in a pachinko machine controlled by a microcomputer having a ROM in which a program is stored for controlling a game.
