Abstract
An electronic timepiece comprises a reference oscillator, a counter for counting reference clock signals from the reference oscillator to obtain a time count signal, and a display device for displaying a time count value of the counter, in which there is provided an input terminal detachably connected to an external data supply device to permit a preset initial count value data to be inputted from the outside. A master device for the timepiece includes an output terminal detachably connected to the input terminal of the timepiece. The preset initial count value data is supplied to the counter of the timepiece through the output terminal which is detachably connected to the input terminal of the timepiece.
Claims16
An electronic timepiece comprising:
- a reference oscillator means for generating reference clock signals;
- count means for counting reference clock signals from said reference oscillator means to obtain a time count value;
- an electroconductive terminal for data input which is to be connected directly to an external data supply device and into which a preset data which is involved during setting of the time is inputted;
- and
- a second electroconductive terminal to which is connected a control signal for writing the preset data from the external data supply device into said count means.
An electronic timepiece apparatus comprising:
- an external data supply device for supplying preset time data and a control signal;
- an electronic timepiece including a reference oscillator means for generating reference clock signals, count means for counting reference clock signals from said reference oscillator means to obtain a time count value, display means coupled to said count means for displaying the time count value of said count means for time display, a first electroconductive terminal for data input which is to be connected directly to an external data supply device and into which a preset data involved during setting of the time is inputted, and a second electroconductive terminal to which is to be connected to receive a control signal for writing the preset data from said external data supply device into said count means;
- said external data supply device including electroconductive output terminals directly connectable to said first and second electroconductive terminals of said electronic timepiece, and means for supplying the preset data and the input control signal to said electronic timepiece through said electroconductive output terminal.
An electronic timepiece comprising:
- a reference oscillator means for generating reference clock signals;
- count means for counting reference clock signals from said reference oscillator means;
- display means coupled to said count means for displaying the time count value of said count means;
- an electroconductive input terminal for connection directly to an external data supply device for receiving a preset initial value data which is inputted from the outside and for coupling said initial value data to said count means at a time setting time;
- and
- an electroconductive output terminal directly connectable to another external electronic timepiece for supplying the time count value of said count means to said another external electronic timepiece.
