Abstract
An optical reader which is compatible with every environment irrespective of installation and usage environments, thereby enabling uniform manufacturing, satisfactory reading reliance, and operative safety and user-friendliness. The optical unit is mounted on the stage, and there is provided an inclination apparatus which inclines the stage at a desired angle. Thereby, without changing a preset optimal scanning pattern, only its emitting direction becomes freely changeable.
Claims1
An optical device, comprising:
- a bendable housing which has a plurality of reading windows;
- a plurality of optical units accommodated in said housing, the number of said optical units corresponding to the number of reading windows, said optical units generating a plurality of scanning patterns, emitting the plurality of scanning patterns to an optically readable medium, and scanning the optically readable medium near a predetermined position intersecting the plurality of scanning patterns;
- a stage, accommodated in said housing, which mounts an optical system at least necessary to generate the plurality of scanning patterns from among said optical unit;
- and
- an inclination apparatus, accommodated in said housing, which inclines said stage,
- wherein one of said optical units always maintains a steady scanning pattern, and
- wherein said plurality of scanning patterns always cross regardless of a bending state of said bendable housing.
