Abstract

An automatic timekeeping and accounting unit is provided which has particular utility for use by professional persons such as lawyers, accountants, and the like. The unit of the invention keeps track of the person'"'"'s working activities during the day, and it also serves to record the time and subject matter of interrupting telephone calls, if the user so desires, along with information relating to other work activities. The unit to be described also includes a simple switch which converts the unit into an electronic calculator for performing additions, divisions, subtractions, multiplications, and other calculations, similar to the commercially available solid state pocket calculators, without affecting its timing capabilities.

a clock means for establishing the time interval in which a particular work activity occurred;

recording means coupled to said keyboard and to said clock means for recording the aforesaid indicia;

register means coupled to said keyboard for storing the indicia representing the account and the indicia representing the work activity;

electronic calculator and display means for presenting numeric solutions to problems established by manual actuation of the keyboard; and

switching means for selectively connecting the keyboard to said electronic calculator and for simultaneously disconnecting the keyboard from said register means.

2. The automatic timekeeping and accounting unit defined in claim 1, and which includes a telephone switching circuit connected to said clock means;

and manually operated switching means connected to said telephone switching circuit to activate said switching circuit and cause said switching circuit to stop the clock means when the switching means is actuated to indicate that the telephone is being operated.

3. The automatic timekeeping and accounting unit defined in claim 2, and which includes circuit means for maintaining information concerning the interrupted activity in memory in said unit upon activation of said telephone switching circuit.

4. The automatic timekeeping and accounting unit defined in claim 2, and which includes further control circuitry responsive to the activation of said telephone switching circuit for establishing the time interval of a telephone conversation to be recorded by said recording means.
