Abstract
A time adjusting device for an electronic timepiece utilizes a manually rotatable mechanism which generates pulses corresponding in frequency and number with the speed and extent of rotation thereof. Each pulse which is generated is thereafter converted into a plurality of pulses. A manually actuatable switch applies either the normal periodic time pulses to a time counter or the plurality of pulses to the time counter upon actuation to adjust the time count therein.
Claims8
Time adjusting device for an electronic timepiece comprising:
- first means adapted to rotate in accordance with a manual operation;
- second means for generating pulses corresponding in frequency and number with the speed and extent of rotation of said first means;
- third means for converting each pulse from said second means into a plurality of pulses;
- fourth means for generating periodic time pulses;
- time counting means for counting time in response to the receipt of pulses;
- manually actuatable fifth means for normally applying the periodic pulses to said time counting means and for applying the plurality of pulses from said third means to the counting means upon actuation to adjust the time count therein.
Time adjusting device for an electronic timepiece comprising:
- first means mounted for rotation about an axis and axial movement therealong between at least two positions;
- second means for generating pulses corresponding in frequency and number with the speed and extent of rotation of said first means;
- third means for converting each pulse from said second means into a plurality of pulses and at least one multiple of the plurality of pulses;
- switching means controlled by the axial movement of said first means for alternatively applying the plurality of pulses and the multiple thereof to a first terminal;
- fourth means for generating periodic time pulses;
- time counting means for counting time in response to receipt of pulses;
- and manually actuatable fifth means for normally applying the periodic pulses to said time counting means and for applying the plurality of pulses or the multiple thereof at the first terminal to the counting means upon actuation to adjust the time count therein.
