Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent the chronograph drive timing and the magnetic field detection timing from overlapping each other to unnecessarily effect driving with correction drive pulses. A processing unit controls drive circuits so as to drive a time indication motor and a chronograph indication motor with a predetermined timing based respectively on timekeeping information obtained and chronograph measurement information obtained, and effects control such that a magnetic field detecting unit detects a magnetic field with a predetermined timing; when the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit overlap each other, the processing unit changes the magnetic field detection timing for the magnetic field detecting unit so that the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit may not overlap each other.

Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent a non-rotation state at the time of first driving when chronograph measuring operation is reset during motor drive and restarting is effected. When a resetting operation is performed on a reset button during the driving of a motor and a rotation detection circuit detects non-rotation, a drive control unit controls a drive pulse generation circuit such that the control is completed without reversing the polarity of a motor drive pulse output from the drive pulse generation circuit, and that the motor is driven by a drive pulse of the same polarity as that at the time of the previous resetting in response to a starting operation performed on a start/stop button, driving the motor by the drive pulse of the same polarity at the time of restarting after the resetting.

Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent the battery reliability service life time from being exceeded even when the period of time that the chronograph function is used is short, making it possible to prevent failure generation in the chronograph timepiece due to liquid leakage. A 24-hour counter down-counts a period of time that has elapsed starting from 24 hours, and a chronograph counter down-counts the period of time that chronograph measurement operation is performed from a predetermined time; when the count values of the 24-hour counter and the chronograph counter become equal to each other, a processing unit consumes a battery for the residual period of time of the two counters by a battery power consuming unit.

Abstract: A chronograph timepiece makes it possible to make sure that it normally operates at the time of an initial starting operation such as system resetting without having to perform a difficult operation or the like. When a system reset signal is input to a system reset terminal and it is detected that initial starting has been effected, a processing unit enables a time hand and a chronograph hand to move after permitting the time hand to perform a predetermined demonstration hand movement when both a start/stop switch and a reset switch have not been simultaneously operated; when these switches have been simultaneously operated, the processing unit enables the time hand and the chronograph hand to move without permitting demonstration hand movement.

Abstract: When it is judged that a chronograph second counter and a chronograph minute counter have measured a maximum measurement time, a maximum measurement control unit controls a drive pulse generation circuit so as to drive and stop a motor such that chronograph hand stops at predetermined positions. When, in this state, a restarting operation is performed on a start/stop button, a normal chronograph measurement operation is restarted. At this time, a mechanical structure has been restored to a reset state, so that even at the time of restarting after the measurement of the maximum measurement time, the load at the starting operation is the same as that of the normal operation, thus generating no sense of incongruity.

Abstract: In response to an instruction to start time measurement given by a start/stop button, an in-phase drive control unit outputs an in-phase control signal of a predetermined time width to a drive pulse generation circuit such that a stepping motor is driven, instead of by a first drive pulse, by an initial drive pulse of a longer drive time than the drive pulse. The drive pulse generation circuit rotates the stepping motor by a motor drive signal including a plurality of in-phase main drive pulses. The stepping motor is rotated by one of the main drive pulses included by the motor drive signal to rotate the chronograph hands.

Abstract: In a chronograph timepiece in which the chronograph hands are electrically rotated by a motor drive pulse and are mechanically zero-restoring-controlled, a basic drive control unit controls a motor so as to drive the chronograph hands when it is detected by a contact portion and a setting releasing detection portion that the setting of the chronograph hands by a setting mechanism has been released.

Abstract: In response to a system reset signal inputted into a system reset port, a control circuit sets a general-purpose port to a high level first. Then, when a mode A is set in an integrated circuit for electronic timepiece, the control circuit sets the general-purpose output port to a low level after an elapse of a first time and when a mode B is set, it sets the general-purpose output port to a low level after an elapse of a second time. In this manner, a mode information signal having a pulse width corresponding to the mode is outputted from the general-purpose output port. It thus becomes possible to reduce the size without adding a special configuration for mode confirmation and to perform a confirmation in a short time.
