Title:
PULSE MOTOR DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2006074927
Kind Code:
A
Abstract:
To provide a pulse motor driving device that shortens the control time of a plurality of pulse motors.
This pulse motor driving device comprises a pulse motor driving circuit 1 that drives two pulse motors M1, M2; a non-volatile memory 3 that holds excited patterns at the time of stop for each of the pulse motors M1, M2; a CPU 2 that reads out data of the non-volatile memory 3, generates pulse motor excited pattern signals OUT1-OUT4, select signals S0, S1, and outputs the signals to the pulse motor driving circuit 1; and switches 13a-13d, 14a-14d that select at least one of the pulse motors M1, M2 by the select signals S0, S1. One or more pulse motors selected by the switches can be driven simultaneously.
