Abstract
Abstract A motor normally drives a gear-train which controls the hands when the motor is acted upon by pulses it receives from a driving circuit and which come from a divider and a quartz oscillator. In order to set an alarm to the desired time, a stem is moved by means of a crown to a setting position. The gear-train is then driven by a pinion and a wheel meshing with one another. The alarm time is recorded by a counter circuit owing to pulses supplied by a contact of a rotary detector. This time is stored in a memory when a push button is pressed. After the hands are returned to a position indicating the correct time of day, the counter circuit counts the elapsed time, and the alarm is set off when a coincidence circuit detects coincidence between the count of the counter and the data stored in the memory.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
Electronic time-piece comprising: means for displaying time data; means for producing a time base signal; means for producing a first and a second manual command; means for producing a control signal; means responsive to said time base signal and to said control signal for driving said displaying means; means responsive to said time base signal and to said control signal for producing a displaying means position signal; means responsive to said first manual command and to said position signal for storing an alarm time signal; means responsive to said position signal and to said alarm time signal for producing a comparison signal; means responsive to said comparison signal for producing an alarm signal; and means responsive to said manual commands, to said control signal and to said time base signal for producing a difference signal: wherein said control signal producing means is responsive to said comparison signal, to said difference signal and to said manual commands for producing said control signal.
Claim 2
Dependent Claim
161 words
Electronic time-piece comprising: means for displaying time data; means for producing a time base signal; means for producing a first and a second manual command; means for producing a control signal; means responsive to said time base signal and to said control signal for driving said displaying means; means responsive to said time base signal and to said control signal for producing a displaying means position signal; means responsive to said first manual command and to said position signal for storing an alarm time signal; means responsive to said position signal and to said alarm time signal for producing a comparison signal; means responsive to said comparison signal for producing an alarm signal; and means responsive to said manual commands, to said control signal and to said time base signal for producing a difference signal: wherein said control signal producing means is responsive to said comparison signal, to said difference signal and to said manual commands for producing said control signal.
Claim 3
Dependent Claim
56 words
The electronic time-piece of claim 1 wherein said means for producing a control signal is constructed to control the application of said time base signal to one of said means for driving said displaying means and said means for producing a difference signal, in response to said means for producing a first and second manual command.
Claim 4
Dependent Claim
49 words
The electronic time-piece of claim 1 wherein said means for producing a control signal is constructed to provide rapid pulses to said means for driving said displaying means and said means for producing a difference signal in response to said means for producing a first and second manual command.
Claim 5
Dependent Claim
45 words
The electronic time-piece of claim 1 wherein said means for producing a control signal causes a transfer of a displaying means position signal to said means for storing an alarm time signal in response to said means for producing a first and second manual command.
Claim 6
Dependent Claim
60 words
The electronic time-piece of claim 1 wherein said means for producing a control signal is constructed to direct rapid pulses to said means for driving said displaying means and to said means for producing a difference signal in response to said means for producing a first and second manual command until said means for producing a difference signal is zero.
Claim 7
Dependent Claim
119 words
The electronic time-piece of claim 1 wherein said means for producing a control signal is constructed to direct rapid pulses to said means for driving said displaying means and to said means for producing a difference signal in response to said means for producing a first and second manual command and further wherein said means for driving said displaying means and said means for producing a displaying means position signal receive rapid pulses until said means for producing a comparison signal is zero so that said means for displaying time data displays a memorized alarm time and thereafter delivers rapid pulses to return said means for producing a displaying means position signal to a state corresponding to actual time.
