Abstract

PURPOSE: To increase the reliability of the accuracy for read-in, by enabling the effective dispersion of the sacanning position, through the selection of the direction tilted for the core center of rotation to the reference shaft of the polygonal column shaped external circumference surface of the rotary mirror provided with the bar code reader.
CONSTITUTION: The oscillator 6 producing the laser beam unidirectionally and the rotary mirror 10 of approximately polygonal column shape constituted with the mirror surface for each surface at external circumference are provided, and the ticket 1 of read-in is scanned with the beam 7 from the revolution of the mirror 10 and conversion is made to the scanning light. Further, the light reflected with the ticket 1 is read in with the optical sensor 13, constituting the optical reader. The surfaces of polygonal column shape 10a, 10b... to the rotary center shaft 16 of the rotary mirror 10 are tilted by a slight angle θ, constituting that the scanning light on the ticket 1 is advanced with slight angle respectively by the surfaces 10a, 10b..., and the canning position is effectively dispersed to the ticket 1.
