    • A stepping motor control circuit includes a rotation detecting means for detecting an induced signal generated by rotation of a rotor of a stepping motor, and detecting a rotation state of the stepping motor according to whether the induced signal exceeds a predetermined reference threshold voltage in a predetermined detection section, and a control means for controlling driving of the stepping motor by using any one of a plurality of main driving pulses having energy different from each other or a correction driving pulse having energy higher than energy of each main driving pulse according to a detection result of the rotation detecting means. The detection section is divided into a first section immediately after driving with the main driving pulse, a second section after the first section, a third section after the second section, and a fourth section after the third section, and the control means lengthens at least one of the first and second sections when the rotation detecting means has detected an induced signal exceeding the reference threshold voltage in the second section.

    • The present invention can rotationally drive a motor with main drive pulses corresponding to loads with the simple constitution without using a counter circuit. A control circuit, in driving a motor with a second main drive pulse, when a rotation detection signal which is indicative of the rotation of the motor is detected by a rotation detection circuit after a predetermined reference time elapses, continues rotational driving of the motor with the second main drive pulse, when the rotation detection signal is detected before the predetermined reference time elapses, changes the rotational driving of the motor with a first main drive pulse having a shorter pulse width than the second main drive pulse, and when the rotation detection signal is not detected, forcibly rotationally drives the motor with a correction drive pulse having a largest pulse width and, thereafter, rotationally drives the motor with the first main drive pulse.

    • To be able to promote oscillation start characteristic while having a simple constitution and maintaining low power consumption. In starting to oscillate an oscillation circuit, a capacitor for protecting from leakage is shortcircuited by bringing a switch of an oscillation stabilizing circuit 11 into a closed state and a constant voltage circuit starts to oscillate the oscillation circuit by supplying a drive voltage of a power source voltage to the oscillation circuit. After an elapse of a predetermined time period, oscillation is prevented from being stopped by leakage by inserting the capacitor into the oscillation circuit loop by bringing the switch into an open state, and an oscillation operation is continued by supplying a voltage lower than the power source voltage to the oscillation circuit by intermittently driving the constant voltage circuit.
