PURPOSE:To shorten a data processing time by eliminating the waste of receipt issue for a customer which do not require a receipt by operating a key for printing. CONSTITUTION:Data on every customer is stored in a memory which is controlled by a control circuit 1. A retrieval key 3 is operated to input retrieval data for retrieving desired data to a retrieving circuit 4. The retrieving circuit 4 is connected to the control circuit 1 and retrieves data in the memory 2 with the retrieval key 3. Consequently, a receipt is issued properly at a customer's request only for a customer who requires the receipt, and a waste of data processing is eliminated, thereby shortening the processing time. |
