Abstract
An electronic timepiece with date display function reduces power consumption in conjunction with the user adjusting the date, and makes it easier for the user to set the date. A displayed date detection unit H has a day detector H1 for detecting the displayed day, a month detector H2 for detecting the displayed month, and a year detector H3 for detecting the displayed year. A control unit A controls a calendar mechanism drive unit F according to the date detected by detectors H1 to H3.
Claims27
An electronic timepiece with a date display function, comprising:
- a drive means for driving an actuator;
- a date display means for displaying a calendar date, wherein said date display means is driven by the actuator and is additionally drivable by a user-manipulatable operator;
- a date detecting means for detecting the date displayed by the date display means;
- and
- a control means for determining if the detected date is a non-existent date on a calendar year, and controlling the drive means to advance the date display means so an existing date is displayed by the date display means if the displayed date is a non-existent date.

An electronic timepiece with a date display function, comprising:
- a drive means for driving an actuator;
- a day display means for displaying a calendar day, wherein the day display means is driven by the actuator and is additionally drivable by a user-manipulatable operator;
- a month indicating means driven by the day display means for indicating a calendar month;
- a date detecting means for detecting the day displayed by the day display means and for detecting the month indicated by the month indicating means;
- and
- a control means for determining from the detected day and month if the day displayed by the day display means is a non-existent date on a calendar year, and, if the displayed date is a non-existent date, then controlling the drive means to drive the day display means until an existing date is displayed.
