Title:
DC MOTOR CONTROL DEVICE AND GAME MACHINE
Document Type and Number:
WIPO Patent Application WO/2016/067787
Kind Code:
A1
Abstract:
A DC motor control device 1 having: communication units (10, 11) that receive a control command specifying a target rotation amount for DC motors (2-1, 2-2); sensor interface units (13-1, 13-2) that receive detection signals from rotational angle sensors (4-1, 4-2) that output the detection signals every time the DC motors rotate by a prescribed rotational angle; step counting units (14-1, 14-2) that output a count signal every time the detection signal has been received a prescribed number of times; control units (15-1, 15-2) that, by means of the number of times a count signal is received, determine a step count representing the total amount of rotation from the beginning of the rotation of the DC motors, and that generate control signals that control the DC motors in accordance with the step count and a target rotation amount; and drive signal generation units (16-1, 16-2) that generate drive signals that rotate the DC motors in accordance with the control signals.
