Abstract
The present invention relates to an optical reader for scanning a surface to be scanned by using information beam ray such as laser beam ray and optically reading a recorded information such as bar code recorded in the surface to be scanned. The optical reader is constituted such that optical beam emitted from a light source is reflected on a first rotary multiface mirror to scan on a surface to be scanned, and information beam reflected on the surface to be scanned is reflected on a second rotary multiface mirror to guide to an opto-electric transforming means. A scanning optical path for permitting the optical beam from the light source to pass therealong is formed independently from a reflecting optical path for permitting the information beam from the surface to be scanned to pass therealong. A condensing lens system including a bore diameter large enough to cover the scanning optical path and reflecting optical path as well as a single optical axis is disposed between the surface to be scanned and the first and second rotary multiface mirrors.
