Embodiment Construction

[0021] Embodiments of the present invention are now shown with reference to the drawings.

[0022] 1. Example structure of game console

[0023] The gaming machine according to the present embodiment is discussed by taking a hybrid slot machine as an example. However, the present invention is not limited to the gaming machine described here, and can be applied to any gaming machine such as a pachinko machine as long as the gaming machine includes a stepping motor for driving a mechanism such as a reel (also called a drum). .

[0024] figure 1 is an external perspective view showing the slot machine according to the present embodiment. Such as figure 1 As shown, the slot machine 1 has a cabinet 2 forming the periphery of the slot machine and an upper liquid crystal display 3 provided on the front upper portion of the cabinet 2 . A lower liquid crystal display 4 is arranged at the front middle part of the cabinet 2 . The upper liquid crystal display 3 is realized as a gene...

Abstract

A stepping controller and gaming machine. A stepping motor controller includes: a pulse frequency adjustment circuit that receives a command pulse having a first frequency from an external controller that outputs the command pulse in accordance with an interrupt process performed periodically by the external controller, and generates an alternative command pulse having a second frequency that is lower than the first frequency; and a motor driving circuit that receives the command pulse through the pulse frequency adjustment circuit, and controls a stepping motor to rotate on the basis of the command pulse. The pulse frequency adjustment circuit outputs the alternative command pulse to the motor driving circuit instead of the command pulse received from the external controller, when the first frequency exceeds a predetermined level.

Description

technical field [0001] The present invention relates to a stepping motor controller for controlling a stepping motor and a game machine equipped with the stepping motor controller, in particular, to a game machine having a stepping motor as a power source for rotating a reel. Background technique [0002] In game arcades or arcades, gaming machines such as slot machines are installed, which provide games to users by rotating reels (also called drums) on which different kinds of symbols are displayed. The reels stop after spinning, paying out rewards to the player based on the stop symbol on the payline. [0003] In gaming machines having reels, stepping motors are generally used as drive motors for rotating the reels. Since the stepping motor rotates stepwise in response to an input pulse signal (command pulse), the frequency of the command pulse can be changed to change the rotational speed of the stepping motor. In a game machine, using such a stepping motor, reel rotati...
