For a chronograph timepiece that chronograph hands are mechanically reset to zero and electrically driven, the chronograph hands are prevented from being electrically driven while being mechanically locked. A chronograph timepiece that is mechanically reset to zero includes a chronograph motor for driving a chronograph hand, a drive unit configured to drive the chronograph motor according a time measurement operation in response to a starting operation by an operating section, and a control unit configured to control the drive unit. The control unit has a rotation detecting circuit for detecting a rotation status of the chronograph motor. When the rotation detecting circuit detects that the chronograph motor is not rotated after the chronograph motor has been rotated a predetermined time period, driving the chronograph motor by the drive unit is stopped for resetting the time measurement operation.

A stepping motor control circuit includes a rotation detection portion that detects a rotation condition of a stepping motor, and a control portion that drives and controls the stepping motor by a correction drive pulse P2 having larger drive energy than one of any one of a plurality of main drive pulses P1 each having different drive energy and the respective main drive pulses P1 depending on a detection result of the rotation detection portion. The control portion drives the stepping motor by switching to a fixed drive pulse having drive energy not smaller than drive energy of a main drive pulse P1nmax having maximum drive energy in a case where there is no drive allowance when the stepping motor is driven by the main drive pulse P1nmax having the maximum drive energy. The stepping motor is thus rotary driven normally even in a DC magnetic field.

A stepping motor control circuit includes a rotation detecting means which detects an induced signal generated by rotation of a rotor of a stepping motor, and detects 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 which controls driving of the stepping motor by using any one of a plurality of main driving pulses having energies 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 control means allows the main driving pulse to be down when a rotation state, in which an extra driving force of the main driving pulse is small, continuously occurs by a predetermined first number of times, and allows the main driving pulse to be down even if the rotation state having a small extra driving force does not continuously occur by the predetermined first number of times when a rotation state having a large extra driving force is large has occurred under a condition in which at least the rotation state having the small extra driving force continuously occurs.

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.

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.

An image forming apparatus that picks only necessary pages up from a plurality of originals and copies after aligning in an order of pages so as to reduce a work burden on a user is provided. The image forming apparatus having a copy function includes an identification information extracting portion for extracting identification information (page number and heading information) which identifies originals from image data of read originals, a selecting portion for displaying the extracted identification information and accepting the identification information selected by the user as a target for image formation, and an output portion for printing image data excluding the identification information from the image data of the target for image formation accepted by the selecting portion. Here, the identification information is preferably formed with code information.

A step motor drive circuit has a first transistor pair having first and transistors, a second transistor pair having third and fourth transistors, and fifth and sixth transistors connected in parallel with the first and third transistors, respectively. A driving circuit alternately drives the first transistor pair and the second transistor pair to an ON state in a state of rotating the motor (first stated), and shortcircuits drive terminals of the motor by driving the first and third transistors to an ON state and driving the second and the fourth transistors to an OFF state in a state of braking the motor (second state). The driving circuit drives the fifth transistor to an ON state when the first transistor is driven to the ON state in the second state of the motor, drives the sixth transistor to an ON state when the third transistor is driven to the ON state in the first state of the motor, and drives the sixth transistor to an OFF state when the third transistor is driven to an ON state in the second state of the motor. The fifth transistor and the sixth transistor function as protecting transistors that protect the first to fourth transistors by increasing the electrostatic resistance thereof.
