Abstract

PURPOSE:To obtain an optical reader which can surely and easily reads objects to be read even when they are long and narrow, by constituting the optical reader of a scanning line generating and sending means which generate and sends plural scanning lines and a data reading circuit which scans and reads objects to be scanned and outputs the read content. CONSTITUTION:A laser beam 14 is emitted from a laser oscillator 15 and reaches a hologram disk 11 through a reflecting mirror 9 and the hole of a slit mirror 8. The disk 11 is rotated by a motor 10 and deflects the laser beam made incident on the disk 11. Therefore, different beams are radiated depending on the characteristic of hologram segments and a scanning pattern 12 composed of parallel scanning lines is obtained. Light reflected by a label 13 on which bar code symbols is marked passed through the disk 11 and converted into electric signals by a photoreceptor element 7 after their route is changed by 90 deg. by the slit mirror 8. The electric signals are sent to a recognizing section where they are decoded through a cable 18 after they are amplified by an amplifier 17.
