A sales registration apparatus includes first and second coupling units detachably coupled to each other, a keyboard, connected to the first coupling unit and including numeral setting keys and department keys, for supplying key-in signals through the first coupling unit in accordance with a key operation in response to key-out signals supplied through the first coupling unit, first memory, and first control unit, coupled to the second coupling unit, for supplying the key-out signals through the second coupling unit and for writing a control program and sales registration data in the first memory in response to the key-in signals supplied through the second coupling unit. The sales registration apparatus further has second memory for storing data corresponding to key-in signals program, operation mode setting units, third coupling unit detachably coupled to the second coupling unit, and data setting device, coupled to the third coupling unit, including second control unit for sequentially supplying key data from the second memory to the first control unit through the third and second coupling units in response to the key-out signals supplied through the third coupling unit in a first operation mode.
