Compact and low cost manufactured structure of information code reader
First Claim
1. An information code reader comprising:
- a reader body having a head in which a window is formed;
a light source emitting light to an information code recorded on an object;
an optical sensor disposed within said reader body, said sensor being responsive to an input of a return of the light from the information code through the window to provide a signal indicative thereof; and
an optical mechanism disposed within said reader body to define an optical path along which said return of the light travels from the window to said optical sensor, said optical mechanism including a plurality of reflecting mirrors arranged to reverse orientation of the optical path between the window and said optical sensor.

Abstract
An improved structure of an optical information code reader which is compact in size and may be manufactured at low costs. The code reader includes an optical mechanism disposed to define an optical path along which a return of light from an information code travels from a window formed in a reader body to an optical sensor. The optical mechanism including a plurality of reflecting mirrors arranged to reverse orientation of the optical path between the window and the optical sensor, thereby resulting in a decrease in length of the optical mechanism which allows the overall size of the code reader to be decreased. The reader body is so designed as to enable different types of optical units and different types of head covers to be mounted selectively, thereby allowing different types of code readers to be manufactured at low costs.
