Bar code input electronic timepiece
First Claim
1. In an electronic timepiece of the type having timekeeping means for keeping time and display means for visually displaying time information:
- read-in means for reading in bar code data representative of selected information in bar-coded form and producing corresponding coded data signals;
decoding means for decoding the coded data signals and producing corresponding decoded data signals representative of the selected information in bar-decoded form;
memory means for storing the decoded data signals; and
read-out means for reading out the decoded data signals from the memory means and producing corresponding display drive signals and applying the display drive signals to the display means for visually displaying the selected information.

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.
