Abstract
A scanning device for recognizing and reading bar codes is configured to have a housing that can be mounted on a scanning surface or beneath the scanning surface. The housing contains an internal scanning face unit, which includes a source of laser light, a rotatable polygonal mirror for reflecting the laser light, a plurality of fixedly disposed flat mirrors and a pick-up element for detecting radiation deflected by the bar code. This internal scanning unit can be arranged within the outer housing in four different positions, thereby creating greater flexibility with respect to the mounting of the overall housing.
Claims14
A device for scanning and/or recognizing bar code, comprising:
- a) a scanner housing fixably mountable in or on a goods-handling counter surface;
- and
- b) an single internal unit arranged as a discrete unit within said housing and comprising
- i) a source of laser light,
- ii) a rotatable polygonal mirror for reflecting the laser light,
- iii) a plurality of fixedly disposed flat mirrors, and
- iv) a pick-up element for picking up radiation scattered by the bar code,
- wherein said single internal unit is placeable in said scanner housing in two or more positions having an angular difference between one another of 90 degrees or 180 degrees to change scan direction or pattern, without altering position of said scanner housing with respect to said counter.
