Abstract:
A driving circuit for a motor, comprising:a switch which may be turned on and off;a counter which counts up during a time when the motor is being driven, and counts down during a time when the motor is stopped;determination means for determining whether a count value counted by said counter is equal to or greater than an upper limit value and for determining whether the count value is equal to or less than a lower limit value, the lower limit value being less than the upper limit value; anda controller which when the switch is turned off in a state in which the count value is equal to or greater than the upper limit value, stops the motor, and which, when the motor is stopped in a state in which the count value is equal to or greater than the upper limit, maintains a stopped state of the motor until the count value is equal to or less than the lower limit value even if the switch is turned on.
