Title: Information symbol reader
Inventor: OBATA KENZO
IPC: G06K7/015
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To enable an operator to easily read out an information symbol by notifying him of both of a visual field range and a focus position. SOLUTION: When an information symbol is located at a determined focal distance of an image pickup lens 206, guide beams projected from respective light emitting diodes 205a to 205c clearly form respective images, but when the symbol and the lens are located at far or near positions, formed images are blurred.
