Abstract: An invention allows a stepping motor to be reliably driven to rotate when initializing the driving and allows power consumption of the stepping motor to be reduced. The controller, when initializing the driving (for example, replacing a battery), controls a main drive pulse generator to drive a stepping motor using a main drive pulse having a maximum energy and sets the generation cycle of a pulse down control signal of a pulse down counter for pulsing down the main drive pulse to a first cycle to drive the stepping motor, and when pulsing down the main drive pulse to that having a predetermined energy, changes the generation cycle of the pulse down control signal of the pulse down counter to a second cycle.

Abstract: To make a setting as to whether or not a time code is automatically received simple, and suppress a wasteful use of an electric power by a reception operation under an environment incapable of suitably receiving the time code. A reception circuit receives and outputs the time code through an antenna, and a control circuit corrects a time instant which is being clocked to a time instant corresponding to the time code. If a crown is operated to a time instant correction position, an input circuit outputs an operation signal denoting this. The control circuit responds to the operation signal to thereby control a reception operation of the reception circuit to OFF. At this time, a time instant correction is performed by hand by operating the crown.

Abstract: 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.

Abstract: The present invention aims to prevent a nonrotation state from being brought about even when a drive allowance is changed by variations in a stepping motor or the like. A pulse down counter circuit outputs pulse down control signal for subjecting main drive pulse to control pulse down when time is counted for a predetermined time period. When a detecting signal exceeding a reference threshold voltage detected by a rotation detecting circuit is detected at a first detection section at start of a rotation detecting time period, a control circuit resets the pulse down counter circuit. Thereby, a main drive pulse generating circuit is not subjected to control pulse down by the pulse down counter circuit, and therefore, it is prevented that the main drive pulse is subjected to pulse down unnecessarily.

Abstract: The present invention aims to generate a proper drive pulse in accordance with a motor. A plurality of duty generating circuits each generates a signal at a duty ratio different from one another. A main drive pulse generating circuit uses an output signal of the plurality of the duty generating circuits to generate a drive pulse, and a motor driver circuit rotates and drives a stepping motor. The stepping motor drives the hands of a display unit. When a rotation detecting circuit detects that the stepping motor is not rotated, a correction drive pulse generating circuit uses a signal from one of the duty generating circuits to output a correction drive pulse, and the motor driver circuit forcedly rotates and drives the motor by the correction drive pulse.

Abstract: It is made possible to display a time instant and a reception sensitivity even during a standard radio signal is received, without adding a special constitution as much as possible. A reception circuit receives and outputs a time code included in the standard radio signal, through an antenna, and a control circuit corrects a time instant being clocked to a time instant corresponding to the time code.
