ABSTRACT:
A sales data processing apparatus has a stock data memory for storing stock data indicating the stock of each item. When sales of a certain item are registered, a value corresponding to a registered number is subtracted from the stock data corresponding to the item. When the item is put into stock, the stock-in number is added to the stock data. The apparatus has a detector for detecting that the stock data has reached a predetermined value. When the detector detects that the stock data has reached the predetermined value, date and time data at this time are stored in an out-of-stock date and time memories, respectively. By switching a mode switch, the out-of-stock date and time data are subtracted from current time data, thereby calculating out-of-stock period data indicating the period the item has been in the out-of-stock state.
