摘要:
A portable laser diode scanning head, aimable at each symbol to be read, emits and receives non-readily-visible laser light, and is equipped with a trigger-actuated aiming light arrangement for visually locating and tracking each symbol. A compact laser diode optical train and an optical folded path assembly, as well as an interchangeable component design and an integral window construction for the head also are disclosed.
摘要:
A target bearing a coded indicium is found by a system for electro-optically reading indicia. Upon the determination that the indicium is located within a range of working distances relative to a hand-held housing, a user is prompted that the indicium is ready to be read. A sonic signal is transmitted by a ranger, and a return echo from the indicium is received. An auditory prompt, such as a single tone or a series of tones, advises the user that the indicium is within range.

摘要:
An auditory beeper mounted in a hand-held scanning head of an electro-optical system for reading light-reflective indicia signals a user that the indicium has been found and is ready to be read by generating a series of sounds or beeps whose rate of beeping changes upon finding the indicium.
摘要:
A region of light-reflective indicia is visibly illuminated in order to locate the indicia relative to a hand-held of a system for electro-optically reading the indicia. The region is formed by aiming optics and a light source for generating a visible aiming beam. The region can be single spot, a pair of spots, or a line.
