PURPOSE:To print successively the contents of a buffer memory and to issue a receipt in response to a request of a purchaser, by providing an issue commanding circuit which generates a receipt issue command signal with operation of a receipt issue key. CONSTITUTION:A receipt issue stop switch is turned on, and the input numerical value and department signals are converted into codes by a decoding circuit and supplied to an arithmetic control circuit. The arithmetic control circuit feeds the unit price of articles to a print data circuit 8-4 via a unit price register 8-1. The circuit 8-4 produces a print data to be transferred to a print buffer in accordance with the contents of the register 8-1 and a sales total register 8-2 as well as the key information. An address signal producing circuit 8-3 uses a decoder signal as an input and produces an address signal of a buffer memory for issue print. In other words, this address signal is reset when a transaction is started and increased successively every time an item is registered. |
