Abstract
Abstract An electronic timepiece in which scheduled time data on specified date or on specified day of the week are set into a counter and their contents are displayed. When the scheduled time comes, an alarm sound is generated. If specific data are inserted instead of the instruction data representative of the date or the day of the week, the timepiece generates the alarm sound repeatedly at the scheduled time. A number of scheduled contents can be set using the same circuit construction and set action for generating repeatedly the alarm sound can be made easily.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
205 words
An electronic timepiece comprising: a first counting circuit for counting time and at least one of date and the days of the week; a first storage circuit for storing scheduled time and providing a corresponding output; a first coincidence circuit for detecting the coincidence between time data from the first counting circuit and the output from the first storage circuit; a second storage circuit for storing at least one from among data representative of the date, the days of the week and data consisting of a predetermined code and providing a corresponding output; a second coincidence circuit for detecting the coincidence between the data from the second storage circuit and said at least one of date and the days of the week; a display unit for displaying information representative of the output from the second storage circuit; an alarm sound signal control means for controlling the occurrence of an alarm sound in response to both outputs of the first and second coincidence circuits; means for effecting reset of the second storage circuit; and a control circuit for controlling the reset action of the first and second storage circuits in response to at least an alarm sound stop signal from the alarm sound signal control means.
Claim 2
Dependent Claim
205 words
An electronic timepiece comprising: a first counting circuit for counting time and at least one of date and the days of the week; a first storage circuit for storing scheduled time and providing a corresponding output; a first coincidence circuit for detecting the coincidence between time data from the first counting circuit and the output from the first storage circuit; a second storage circuit for storing at least one from among data representative of the date, the days of the week and data consisting of a predetermined code and providing a corresponding output; a second coincidence circuit for detecting the coincidence between the data from the second storage circuit and said at least one of date and the days of the week; a display unit for displaying information representative of the output from the second storage circuit; an alarm sound signal control means for controlling the occurrence of an alarm sound in response to both outputs of the first and second coincidence circuits; means for effecting reset of the second storage circuit; and a control circuit for controlling the reset action of the first and second storage circuits in response to at least an alarm sound stop signal from the alarm sound signal control means.
Claim 3
Dependent Claim
38 words
An electronic timepiece according to claim 1, further including manually operable setting means for advancing the count of at least one of said first and second storage means in accordance with pulses developed in response to manual operation.
