摘要： An entirely field-portable laser scanning system for reading boar code symbols includes a light-weight and small-sized laser scanning head. The laser source, power supply component, optics, scanning elements, sensor circuit, and signal processing circuitry are specially designed for minimal size and weight and volume such that they can all be mounted in the head. The head can be bracket-mounted or hand-held. The housing for the head can be provided with a handle grip, or can be gun-shaped. High-speed oscillating scanning motors and/or penta-bimorph scanners are used as scanning elements. A trigger initiates repetitive scanning of each object bearing a symbol, and an indicator indicates when the scanning of that particular object has been terminated. A body harness supports the remaining scanner system circuitry. A non-bulky, freely-movable cable interconnects the head to the body harness. Methods of scanning the symbol and of operating the system are also disclosed.

摘要： A portable, stand-alone, desk-top, laser scanning workstation includes a laser scanning head mounted above a support base. Objects bearing bar code symbols to be scanned are passed underneath the head for overhead scanning, or are passed along one side of the head for sideward scanning. The symbols are oriented face-up towards the handler all during their passage through the workstation to facilitate sighting and registration of the symbol with the laser light beam generated by the head. The workstation is self-supporting, is fully portable, can process objects of different sizes, and grants access to objects from either side of the workstation. The workstation is connected to a microprocessor-based microcomputer which is mounted within a desk-top console, as well as to a variety of peripheral devices such as a printer, a keyboard, a communications port, audio-visual annunciators and a data display. The workstation, console and peripheral devices all constitute an intelligent laser-based data acquisition terminal for use in a variety of applications.

摘要： Laser light reflected from a bar code symbol pattern is detected by a photodetector mounted in a portable scanning head of a laser scanning system. By selecting appropriate threshold values on the analog signal generated by the photodetector, the analog signal is converted to a series of pulses, each pulse width accurately corresponding to the width of a bar from the scanned pattern. A plurality of functions can be determined from the series of pulses, each function being independently selected by keyboard entry from the head, displayed on the head, and/or recorded by a printer remote from the head. Single line or multiple line scans in two orthogonal directions relative to the pattern may be selected. A bimorph or speaker-type oscillatory element may be utilized as a miniature scanning element. Circuitry for synchronizing scanning along both axes, and for generating a signal to drive the bimorph in a uniform, constant velocity manner is also disclosed.

摘要： A hand-held bar code reader including a housing bounding an interior, a window, a generally planar printed circuit board mounted in the interior, and an optical scanning assembly mounted on the board and including a scanner for directing a light beam through the window at an acute angle relative to the board. A scanning element of the reader is manufactured by spacing a first and second support element apart by a gap bounded by edges of the support elements; injection molding a curable, elastomeric material in flowable form over the edges and into the gap; and allowing the curable, elastomeric material to cure and bond to the edges, and form a flexible hinge in the gap for enabling movement of the support elements relative to one another both away from and toward a stable rest initial position.

摘要： An arrangement for determining light beam position in an electro-optical reader, image projector and like devices includes a drive for moving a scanning light beam at a scan frequency across a target as a scan line, and an electro-optical feedback assembly operatively connected to the drive, for optically detecting scan line position during beam movement, and for generating a feedback signal at the scan frequency, the feedback signal being indicative of the scan line position. A feedback coil in the drive is eliminated to avoid electromagnetic coupling between multiple coils in the drive.

摘要： A compact assembly for electro-optically scanning indicia includes an oscillatable component operative for focusing, and for sweeping, a light beam across the indicia and, optionally, for correcting for scan aberration. A laser diode for emitting the beam is inserted into a central opening surrounded by an electromagnetic coil to conserve space. A magnet on the component interacts with the coil to effect oscillation. A floating flexure returns the component to an equilibrium position.
