<p><P>PROBLEM TO BE SOLVED: To prevent occurrence of a fault, such as ignition of a game machine, by providing a game machine for promptly detecting no-load operation of a stepping motor. <P>SOLUTION: A Pachinko game machine 1 includes: a decorative movable body 42; a first stepping motor 63 and a second stepping motor 67, namely drive sources of the decorative movable body; drive control means (composed of a lamp control board 24, a drive circuit 96, and a drive circuit 104) of controlling drive of both the motors 63, 67; measurement means (composed of voltage measurement parts 100, 108, A/D conversion parts 101, 109, and a lamp control board 24) of measuring an energizing waveform to both the motors from the drive control means; and a determination means (composed of the lamp control board 24) of determining a drive state of both the motors, based on energizing waveform information measured by the measurement means. When the determination means determines that either motor is operated continuously without any loads for at least predetermined time, the drive control means stops drive of both the motors. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
