Abstract
Abstract A printer calculator includes a time information keeping circuit for storing current time information. A state detection means is provided in the printer calculator for printing out the current time information stored in the time information keeping circuit when a preselected state occurs in the printer calculator. The state detection means can be responsive to, for example, actuation of a particular key included in a keyboard panel of the printer calculator, and/or initiation of power supply to the printer calculator.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
An electronic calculator system having a printer for printing desired data produced by said calculator system, said system comprising: a time generator for producing data representative of current time information; counter means for producing an incremental count and for generating an output signal when said count reaches a predetermined level; and printing selection means responsive to the output signal generated by said counter means for converting said current time information produced by said time generator into desired data and presenting this data to said printer; said printer printing said time information when count within said counter means reaches a predetermined level.
Claim 2
Dependent Claim
101 words
An electronic calculator system having a printer for printing desired data produced by said calculator system, said system comprising: a time generator for producing data representative of current time information; counter means for producing an incremental count and for generating an output signal when said count reaches a predetermined level; and printing selection means responsive to the output signal generated by said counter means for converting said current time information produced by said time generator into desired data and presenting this data to said printer; said printer printing said time information when count within said counter means reaches a predetermined level.
Claim 3
Dependent Claim
16 words
The system of claim 1 wherein said data representative of current time information includes date information.
Claim 4
Dependent Claim
34 words
The system of claim 1 wherein said printer includes a print receiving paper strip; and wherein said print selector means is further responsive to the presence of the trailing edge of said paper strip.
Claim 5
Dependent Claim
113 words
An electronic calculator system having a printer for printing desired data produced by said calculator system, said system comprising: a time generator for producing data representative of current time information; program memory means for storing a program representative of times where a printout of said current time information is desired; coincidence determination means for producing an output signal when one of the times stored in said program memory means coincides with said data representative of current time information; and printing selector means responsive to the output signal generated by said coincidence determination means for converting said data representative of current time information into desired data and presenting this desired data to said printer.
Claim 6
Dependent Claim
113 words
An electronic calculator system having a printer for printing desired data produced by said calculator system, said system comprising: a time generator for producing data representative of current time information; program memory means for storing a program representative of times where a printout of said current time information is desired; coincidence determination means for producing an output signal when one of the times stored in said program memory means coincides with said data representative of current time information; and printing selector means responsive to the output signal generated by said coincidence determination means for converting said data representative of current time information into desired data and presenting this desired data to said printer.
Claim 7
Independent Claim
22 words
The system of any of claims 1 or 4 wherein said data representative of current time information includes time of day information.
