Abstract

PURPOSE:To achieve the miniaturization of the device and its less electric power consumption by converting beam light to a scanning beam by a rotary mirror, branching the same in two directions by a half mirror and providing the optical system leading one beam light to the 1st scanning part and the optical system leading the other beam to the 2nd scanning part, in a postal code number read classifier. CONSTITUTION:The light beam from a laser oscillator 1 is focused by a focusing lens 2 and is converted to a scanning beam (l0) by a rotary mirror 3. The scanning beam light (l0) reflects on, e.g. half mirror 4 and its scanning beam (l1) is led to the 1st scanning part for postal matter p by way of a mirror 5 and ftheta lens 6. The light reflected from the postal matter P is led to a photoelectric converter 11 by way of a condenser lens 10. On the other hand, the beam (l2) transmitted through the half mirror is led to the 2nd scanning part for the postal matter P by way of a mirror 12, movable mirror 13 and ftheta lens 14. The reflected beam light thereof enters a photoelectric conversion part 18 by way of a condenser lens 17. Thereby, the miniaturization and less electric power consumption of the device may be achieved.
