Abstract

An electronic timepiece has a plurality of modes and includes a plurality of indicating hands including a first indicating hand as a mode hand that indicates each mode, an operation section that allows mode switching operation that instructs switching among the modes, and a display control section that moves the plurality of indicating hands to be moved on the basis of the mode switching operation in such a way that periods for which the plurality of indicating hands move in high-speed advance action do not overlap with one another. The display control section first moves the first indicating hand among the plurality of indicating hands.

First claim

What is claimed is:

1 . An electronic timepiece having a plurality of modes, the timepiece comprising:
a plurality of indicating hands including a mode hand that indicates one of the modes; an operation section that allows mode switching operation that instructs switching among the modes; and a display control section that moves the plurality of indicating hands to be moved on the basis of the mode switching operation in such a way that periods for which the plurality of indicating hands move in high-speed advance action do not overlap with one another, wherein the display control section first moves the mode hand among the plurality of indicating hands.

2 . The electronic timepiece according to claim 1 , further comprising
a plurality of motors that drive the plurality of indicating hands under the control of the display control section, wherein the display control section first moves the mode hand and then sequentially moves the other indicating hands in ascending order of motor drive pulses required for the indicating hands to go around.

3 . The electronic timepiece according to claim 1 , further comprising
a chronograph section that measures a period, wherein the plurality of indicating hands include a plurality of measurement indicating hands capable of indicating measured periods measured by the chronograph section, and the display control section moves the mode hand on the basis of chronograph switching operation that is performed through the operation section and instructs measurement of a period, and the display control section, having moved the mode hand, first moves a minimum period measurement indicating hand among the plurality of measurement indicating hands that indicates a minimum period among the measured periods.

4 . The electronic timepiece according to claim 3 ,
wherein when the chronograph section starts measuring a period before the movement of the minimum period measurement indicating hand is completed, the display control section moves the minimum period measurement indicating hand in the high-speed advance action to a position representing the measured period and then allows the minimum period measurement indicating hand to normally operate.

5 . An electronic timepiece having a plurality of modes, the timepiece comprising:
a plurality of indicating hands; a plurality of motors that drive the plurality of indicating hands; an operation section that allows mode switching operation that instructs switching among modes; and a display control section that moves the plurality of indicating hands in high-speed advance action by using the plurality of motors on the basis of the mode switching operation, wherein the display control section sequentially moves the plurality of indicating hands in ascending order of motor drive pulses required for the indicating hands to go around in such a way that periods for which the indicating hands move in high-speed advance action do not overlap with one another.
