Abstract
PURPOSE: To improve the operation of a hand scanner in an optical reader by continuing a read while a bar code signal is being detected.
CONSTITUTION: The reflected light of a scanning beam swung continuously by hand scanner 5 is converted by photoelectric converter 1 into an electric signal, which is supplied to bar code decoder 4 via comparator 2 and also supplied to bar code discriminator 3. Then, discriminator 3, when pulses of its input signal are continuously generated within the prescribed intervals, regards it as a bar code signal to control the operation of decoder 4. Therefore, making scanner 5 approached bar codes, a bar code signal is obtained and since decoder 4 decodes the signal automatically only when the bar code is inputted, the switching operation for the start and stop of read is made unnecessary, so that the operation can be improved.
