Abstract
A data processing apparatus for an electronic cash register comprises a keyboard having a plurality of entry keys, a printer, a memory unit, an interface circuit with which a memory pack storing sales data is mechanically, electrically and removably coupled and a data processing unit connected with the keyboard, the printer, the memory unit and the interface circuit. Responding to operations of one of the keys for sales data selection, the data processing unit energizes the memory pack connected to the interface circuit to read out the sales data corresponding to the operated sales information key from the energized memory pack and write the read-out sales data into the memory unit and then issue a print signal to the printer for printing the sales data.
