Patent US 4,482,976

A voice data output apparatus for an electronic cash register comprises in turn a voice output circuit which in turn judges as to whether or not the input money data is a first registered number and which outputs a greeting voice, e.g., "WELCOME" when it is in fact the first registered number. A CPU is connected to an input circuit, a print circuit, a display circuit, a RAM and the voice output circuit through chip designating signal lines, an R/W signal line, an address bus line, and a data bus line. Chip designating signals are supplied from the CPU to the above-mentioned respective circuits for selecting a circuit to be used among these circuits. The display circuit and the voice output circuit are selected by the same chip designating signal. When a first registered number of the money data is input from the input circuit, the voice output circuit outputs a voice "WELCOME" according to the data "1" stored in a flag storing region of the CPU of this circuit, and thereafter rewrites the content of the flag storing region to "0". When a CASH/MONEY RECEIVED KEY of the input section of the input circuit is operated, the content of the flag storing region is rewritten to "1" for waiting for input of the money data for a next customer.
