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.
