Abstract
Abstract The disclosed is an electronic timepiece which has storage circuits for respectively storing data regarding a variety of times such as an alarm time for different operating modes, stop watch, timer, etc., a data processing circuit commonly provided for all the storage circuits for executing various time processes, and a control circuit for controlling a mutual transfer of the data between the respective storage circuits and the data processing circuit to selectively process the various times. Accordingly, this timepiece can process a large number of times without increasing the number of the time processing circuits.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
84 words
An electronic multi-function timepiece, comprising: first counting means for developing a count representative of time; storage means for simultaneously storing a plurality of counts corresponding to a plurality of additional functions of the timepiece; selecting means connected to said storage means for selecting any of the additional timepiece functions; second counting means for developing a count corresponding to the additional function selected by said selecting means; and control means for controlling mutual transfer of counts between said second counting means and said storage means.
Claim 2
Dependent Claim
84 words
An electronic multi-function timepiece, comprising: first counting means for developing a count representative of time; storage means for simultaneously storing a plurality of counts corresponding to a plurality of additional functions of the timepiece; selecting means connected to said storage means for selecting any of the additional timepiece functions; second counting means for developing a count corresponding to the additional function selected by said selecting means; and control means for controlling mutual transfer of counts between said second counting means and said storage means.
Claim 3
Dependent Claim
16 words
An electronic timepiece according to claim 1, wherein said second counting means is an up-down counter.
Claim 4
Dependent Claim
118 words
An electronic multi-function timepiece, comprising: a preset counter for developing a count representative of time; storage means for simultaneously storing a plurality of counts corresponding to a plurality of additional functions including a time correcting function of the timepiece; selecting means connected to said storage means for selecting any of the additional timepiece functions; second counting means for developing a count corresponding to the additional function selected by said selecting means; control means for controlling mutual transfer of counts between said second counting means and said storage means; and correcting means for allowing said selecting means to select the time correcting function and for storing a desired time adjusted by said second counting means in said preset counter.
Claim 5
Dependent Claim
118 words
An electronic multi-function timepiece, comprising: a preset counter for developing a count representative of time; storage means for simultaneously storing a plurality of counts corresponding to a plurality of additional functions including a time correcting function of the timepiece; selecting means connected to said storage means for selecting any of the additional timepiece functions; second counting means for developing a count corresponding to the additional function selected by said selecting means; control means for controlling mutual transfer of counts between said second counting means and said storage means; and correcting means for allowing said selecting means to select the time correcting function and for storing a desired time adjusted by said second counting means in said preset counter.
Claim 6
Dependent Claim
168 words
An electronic multi-function timepiece, comprising: a preset counter for developing a count representative of time; storage means for storing a plurality of counts corresponding to a plurality of additional functions including a time correcting function and an alarm time function of the timepiece; selecting means for selecting any of the additional timepiece functions; second counting means for developing a count corresponding to the additional function selected by said selecting means; control means for controlling mutual transfer of counts between said second counting means and said storage means; correcting means for allowing said selecting means to select the time correcting function and for storing a desired time adjusted by said second counting means in said preset counter; main display means for normally indicating present time; sub display means for normally indicating an alarm time; and switching means for switching the indication of said main display means to the additional function selected by said selecting means and the indication of said sub display means to that of the present time.
Claim 7
Dependent Claim
168 words
An electronic multi-function timepiece, comprising: a preset counter for developing a count representative of time; storage means for storing a plurality of counts corresponding to a plurality of additional functions including a time correcting function and an alarm time function of the timepiece; selecting means for selecting any of the additional timepiece functions; second counting means for developing a count corresponding to the additional function selected by said selecting means; control means for controlling mutual transfer of counts between said second counting means and said storage means; correcting means for allowing said selecting means to select the time correcting function and for storing a desired time adjusted by said second counting means in said preset counter; main display means for normally indicating present time; sub display means for normally indicating an alarm time; and switching means for switching the indication of said main display means to the additional function selected by said selecting means and the indication of said sub display means to that of the present time.
