摘要：
An optical scanner suitable for use with a bar code reader is disclosed. The optical scanner comprises a light source (24) for generating a laser beam, a laser beam scanning device (23), a scanning pattern generating optical system (34), and a signal light condensing optical system (18,21) for deflecting scattered signal light scattered by an object to be read to introduce the light to a photo-detector (20). The invention realizes miniaturization of the apparatus by employing at least one hologram of the reflection type for the scanning pattern generating optical system (34) and/or the signal light condensing optical system( 18,21).
