摘要： A narrow-bodied, single- and twin-windowed, hand-held, laser scanning head for reading bar code symbols includes at least one window mounted at the rear region of the head, and through which either the incident beam going to the symbol and/or the reflected beam returning from the symbol, passes unobstructedly and exteriorly of, and past, the front and intermediate body regions of the head. A field-replaceable laser tube arrangement, a laser tube and method of making the same, an arrangement for and method of controlling a scanning system, optical passive elements for increasing the depth of field, a trigger protective device, and a one-piece support bench and method of fabricating the same by mass-production techniques are also disclosed.

摘要： In a system for electro-optically reading bar code symbols, a movable reflector is rearwardly positioned in a hand-held housing. A sensor receives light reflected off a bar code symbol from the reflector over a scan that extends across the entire bar code symbol. The housing has a window, a front end and a handle for enabling a user to hold and support the housing in one's hand, and to aim the front end of the housing at the bar code symbol during reading. A signal processor in the housing processes an electrical signal from the sensor to generate therefrom data descriptive of the bar code symbol being read. The reflector is positioned at a distance from the front end of the housing, and the length of the scan is proportional to that distance.

摘要： In a system for electro-optically reading bar code symbols, a movable reflector is positioned for directly receiving light reflected off a bar code symbol, and for reflecting this light to a sensor. The reflector movement provides the sensor with a field of view that extends across the entire bar code symbol. The reflector and the sensor are mounted in a housing having a handle for enabling a user to hold and support the housing in one's hand, and to aim the housing at the bar code symbol during reading. A signal processor in the housing processes an electrical signal from the sensor to generate therefrom data descriptive of the bar code symbol being read.
