Abstract

An electronic timepiece inputs bar code data, decodes the data and displays decoded information represented by the bar code data. An optical sensor scans bar codes printed on a paper and inputs corresponding electrical bar coded data signals to an amplifier. A digitizer digitizes the amplified signals into serial digital signals which are decoded by a decoder into parallel bar-decoded data signals. A buffer memory temporarily stores the decoded data signals during read-in of the bar code data, and a memory control circuit controls the transfer of the decoded data signals from the buffer memory to a main memory. A selector circuit selects the decoded data signals from either the buffer memory or the main memory for visual display via a display decoder/driver circuit.
