PURPOSE:To eliminate the part, where registration history data is recorded, from the sales register part where commodity sales data of one transaction is registered. CONSTITUTION:A terminal 1 for sales registration of commodity sales data of one transaction and a history recorder 2 are connected by a communication line 3. The terminal 1 prints and issues a receipt of the registered transaction by a receipt printer and transmits registration history data of this transaction to the history recorder 2 through the communication line 3. The history recorder 2 receives registration history data to write and record this data on a hard disk in the reception order. |
