Inventor: OKAWA MASANORI
IPC: G02B26/12
Filed: 1998-10-21
Abstract: PROBLEM TO BE SOLVED: To enhance the degree of freedom in the arrangement of a pattern mirror and to improve the condensing efficiency of reflected light from a bar code by arranging a scanning means so that the turning axis of the scanning means may face nearly in a horizontal direction with respect to a horizontal surface. SOLUTION: The rotary axis of a polygon mirror being one example of the scanning means performing scanning with a laser beam emitted from a light source LD is set at a position nearly in parallel with a bottom window (the same as the sliding surface of an article substantially). To say more minutely, the rotary axis is set to face downward by about 5 deg.. The inclination of the rotary axis of the polygon mirror is properly changed in accordance with design. The polygon mirror is constituted to make the laser beam incident from its below part and reflect and emit scanning light toward the below part. Therefore, the reflection surface of the polygon mirror faces downward substantially. Thus, neither the light source nor the scanning means are installed in the housing of a bottom part.
