Abstract
Abstract A cash register system has a memory for storing the present time data counted by a time counting circuit and the present date data, and a memory for storing date changing data indicating a changing range of a data changing time with respect to a date renewal time on a calender day. When all the sales data are read out from a total memory and calculated in a total manner, the present time data and the date changing data, which are read out from the said memory means by a CPU, are compared with each other. When the former is not within the latter, the present time data is output as the date data of total calculation data. On the other hand, when the former is within the latter, the present date data is modified to have another date data, and the latter data is output as the date data for total calculation data.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
In a data processing system for use in electronic cash registers comprising: a time counting means for counting present time data and present date data; a first memory means connected to said time counting means storing said present time data and said present date data; a preprogrammed second memory means for storing date changing data comprising a date changing range indicating a period of time in a day during which date data is to be changed; date data changing means connected to said first and second memory means for detecting if the present time data falls within the date changing range and changing the present date data to another date data when said present time data is within said date changing range; and outputting means connected to said date data changing means for outputting said present date data as the date data for a total calculation of all sales data if the present time data falls outside said date changing range at the time of the total calculation of all sales data and outputting said another date data as the date data for the total calculation of all sales if the present time data is within said date changing range.
Claim 2
Dependent Claim
200 words
In a data processing system for use in electronic cash registers comprising: a time counting means for counting present time data and present date data; a first memory means connected to said time counting means storing said present time data and said present date data; a preprogrammed second memory means for storing date changing data comprising a date changing range indicating a period of time in a day during which date data is to be changed; date data changing means connected to said first and second memory means for detecting if the present time data falls within the date changing range and changing the present date data to another date data when said present time data is within said date changing range; and outputting means connected to said date data changing means for outputting said present date data as the date data for a total calculation of all sales data if the present time data falls outside said date changing range at the time of the total calculation of all sales data and outputting said another date data as the date data for the total calculation of all sales if the present time data is within said date changing range.
Claim 3
Dependent Claim
22 words
The cash register system according to claim 1, wherein the date changing data stored in the second memory means is time data.
Claim 4
Dependent Claim
23 words
The cash register system according to claim 2, wherein the time data comprises a prescribed period of time which starts at 0:00 a.m.
Claim 5
Dependent Claim
28 words
The cash register system according to claim 1, wherein said date data changing means changes said present date data to a date data of the immediately previous day.
Claim 6
Dependent Claim
27 words
The cash register system according to claim 1, wherein said date data changing means changes said present date data to a date data of the next day.
Claim 7
Dependent Claim
152 words
A cash register system comprising: a first time counting means for counting a present time data and a present date data; a second time counting means for counting time data and date data shifted by a predetermined time width with respect to the present time data and date data counted by said first time counting means; memory means connected to said first and second time counting means for storing said present time data and said present date data counted by said first time counting means, and said shifted time data and date data counted by said second time counting means; and outputting means connected to said memory means to output as the date data used for a total calculation of all sales data, the date data based on said shifted time data and date data counted by said second time counting means at the time of total calculation of all sales data.
Claim 8
Dependent Claim
152 words
A cash register system comprising: a first time counting means for counting a present time data and a present date data; a second time counting means for counting time data and date data shifted by a predetermined time width with respect to the present time data and date data counted by said first time counting means; memory means connected to said first and second time counting means for storing said present time data and said present date data counted by said first time counting means, and said shifted time data and date data counted by said second time counting means; and outputting means connected to said memory means to output as the date data used for a total calculation of all sales data, the date data based on said shifted time data and date data counted by said second time counting means at the time of total calculation of all sales data.
Claim 9
Dependent Claim
37 words
The cash register system according to claim 1, wherein said outputting means comprises a transfer means for transferring data read out from said memory means, and printing means for printing said data transferred through said transfer means.
Claim 10
Dependent Claim
37 words
The cash register system according to claim 6 wherein said outputting means comprises a transfer means for transferring data read out from said memory means, and printing means for printing said data transferred through said transfer means.
