PURPOSE:To simplify the design of an arithmetic control part, by providing two counters, namely, a counter for management of the number of stock articles and a counter for management of the number of sold articles and equalizing all departmental processings. CONSTITUTION:The number of stock articles is inputted by the key operation on a keyboard 1 and is written in a counter (b) of a goods departmental register 5 by the depression of a stock number set key. When the sales price is entered by an entry key on the keyboard 1 and its goods departmental key is depressed, a counter (a) of the goods departmental register 5 is counted up by one, and the counter (b) is counted down by one. In case of registration of the multiplication form, the counter (a) is counted up by an entered number of articles, and the counter (b) is counted down by this number. |
