Abstract

PURPOSE:To allow a motor to be driven by a small capacity power source by permitting the drive of the motor when the output voltage of the power source circuit becomes the prescribed value. CONSTITUTION:The output of a power source circuit 5 is monitored by a power voltage monitoring circuit 8. When the output reaches the prescribed voltage, a signal is applied to an AND circuit 12. When the output of the circuit 8 and a tape run command (a) are inputted to the AND circuit 12, a signal for allowing the drive of the motor is applied to a motor driving circuit 6. Thus, the power source can be reduced in capacity.
