optical path which exceeds approximately 0.5cm, at least one, desirably, it is monitored by detecting the light of the wave length where two or more is beforehand selected, one wave length is closely an infrared spectrum, and/or, one wave length visible or closely is an infrared spectrum. ...

The code reading is achieved by transmission and reception of an infra red beam whose space spectrum is corrected by a piece of plastics (5). The plastics piece permits reading of the code at a distance and various incident axes. The plastics piece is 50mm long and has a 4.7mm dia. ...
