Abstract
Abstract In a mode switching type electronic timepiece of the type wherein time correction is made under a correction mode, where the same data is displayed over a predetermined period in the correction mode, the operation of the timepiece is automatically transferred from the correction mode in which power is consumed for the time display to a nondisplay mode in which no power is consumed for the time display or a specific mode in which less power is consumed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
72 words
An electronic timepiece provided with a counter circuit for producing a reset signal upon counting a predetermined number of clock pulses, whereby the operation mode of the timepiece is automatically switched from a correction mode in which power is consumed for the time display to a non-display mode in which no power is consumed for the time display when the same data is displayed over a predetermined period in the correction mode.
Claim 2
Dependent Claim
72 words
An electronic timepiece provided with a counter circuit for producing a reset signal upon counting a predetermined number of clock pulses, whereby the operation mode of the timepiece is automatically switched from a correction mode in which power is consumed for the time display to a non-display mode in which no power is consumed for the time display when the same data is displayed over a predetermined period in the correction mode.
Claim 3
Dependent Claim
297 words
An electronic timepiece comprising a logical time counting circuit for generating a time information, an advance pulse and a clock pulse; a first designation circuit to be set by a signal from first externally operable input means to supply a timing information output designation signal to said logical time counting circuit for causing the same to produce a time information; a display device for displaying a time corresponding to said time information produced by said logical time counting circuit; a second designation circuit to be set by a signal from second externally operable input means to supply a correction mode designation signal to said logical time counting circuit for setting the same to a correctable condition; a logical circuit responsive to a signal produced by said first input means when said logical time counting circuit is set at a correction mode for supplying the advance pulse to a time correction signal input terminals of said logical time counting circuit; a counter circuit for counting the number of the clock pulses produced by the logical time counting circuit for providing a reset signal to said first and second designation circuits when a predetermined number of the clock pulses has been counted thus resetting said first and second designation circuits for stopping the output designation signals produced thereby; said counter circuit being connected to be reset by a signal produced by said first input means; whereby when said display device displays the same data for a predetermined period under a condition wherein said logical time counting circuit is set to said correction mode in which power is consumed for the time display, said timepiece is automatically transferred to a non-display mode in which no power is consumed for the time display by the reset signal from said counter circuit.
Claim 4
Dependent Claim
297 words
An electronic timepiece comprising a logical time counting circuit for generating a time information, an advance pulse and a clock pulse; a first designation circuit to be set by a signal from first externally operable input means to supply a timing information output designation signal to said logical time counting circuit for causing the same to produce a time information; a display device for displaying a time corresponding to said time information produced by said logical time counting circuit; a second designation circuit to be set by a signal from second externally operable input means to supply a correction mode designation signal to said logical time counting circuit for setting the same to a correctable condition; a logical circuit responsive to a signal produced by said first input means when said logical time counting circuit is set at a correction mode for supplying the advance pulse to a time correction signal input terminals of said logical time counting circuit; a counter circuit for counting the number of the clock pulses produced by the logical time counting circuit for providing a reset signal to said first and second designation circuits when a predetermined number of the clock pulses has been counted thus resetting said first and second designation circuits for stopping the output designation signals produced thereby; said counter circuit being connected to be reset by a signal produced by said first input means; whereby when said display device displays the same data for a predetermined period under a condition wherein said logical time counting circuit is set to said correction mode in which power is consumed for the time display, said timepiece is automatically transferred to a non-display mode in which no power is consumed for the time display by the reset signal from said counter circuit.
