    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： Optical alignment between components in a head of a laser scanner is maintained in the event of external shock. Optical and scanning component assemblies are shock-mounted near their respective centers of mass. A flexible, printed circuit board on which the assemblies are mounted serves as an alignment fixture.

    摘要： A scanning head for reading bar code signals including a laser source producing a beam which is scanned across a symbol to be read by a moving mirror arrangement, and a photodetector responsive to light reflected from the symbol. The signal from the photodetector is digitized and decoded to recover bar code data. The scanning head includes a manually actuated input and display device. A microprocessor in the head controls the operation of the various components. A transmitter and receiver may be located in the scanning head for communication with a central computer, and a battery may be included in the head as a power supply so that the scanning head need not be connected by a cable to a terminal.
