Abstract:
1. A reading apparatus that reads identification information attached on an object located outside of the reading apparatus by optically scanning a surface of the object, the reading apparatus comprising: a light source configured to output a light beam; an optical deflecting unit configured to deflect the light beam; an optical scanning unit that receives the light beam from the optical deflecting unit, produces a scan beam from light beam, and emits the scan beam toward the object; a light collecting unit that collects a reflection beam that is a light reflected from the surface of the object; a supporting member that supports the optical deflecting unit and that rotatably supports the light collecting unit; and an optical detecting unit that receives the reflection beam from the light collecting unit so as to detect a barcode attached to the surface of the object, wherein said light collecting unit is rotatable to adjust a focal point of the reflection beam to be on the optical detecting unit, and wherein said optical deflecting unit is positioned behind all of said light collecting unit, with respect to said optical scanning unit.
