BAR CODE PATTERNING DEVICE
Document Type and Number:
Japanese Patent JP3925969
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To detect a reflecting light from a record body and to easily observe or control an emitting light by arranging a deflecting beam splitter on an optical axis of the emitting side of a laser medium and a ray receiving element on an optical passage on the side of the above optical axis from this deflecting light splitter.
SOLUTION: In this laser beam emitting means, orderly toward from an incident beam side to an outgoing beam side, LD (laser diode) alley 6 in which fifty pieces of LD chips are arranged in a row in its bar width a, two pieces of convex cylindrical lenses 8, 9 and a concave smoothing cylindrical lens 7 are fixed on the optical axis and received in a mirror cylinder 10. In the LD alley 6, each LD chip is arranged in the same interval so that its longitudinal direction of emitting part of each LD chip is faced toward the longitudinal direction of the LD alley 6, and it is composed so that all the LD chip is made ON/OFF at the same time. The controlling means 4 controls ON/OFF of the LD alley in several ten μ-sec. based on the information of bar code.
