摘要： A laser scanner includes a laser, a variable focusing element, a scanner, a detector, and a controller that controls the scanner to sweep a laser beam over an aiming angle at an aiming rate to form an aiming line on a symbol during aiming, and over a reading angle at a reading rate to form a reading line on the symbol during reading that follows the aiming. The aiming angle is smaller than the reading angle. The aiming rate is higher than the reading rate. The aiming line is shorter than the reading line. The controller determines a depth of modulation of an analog signal generated during aiming, and controls the variable focusing element to focus the laser beam on the symbol during aiming when the depth of modulation is determined to be optimum. The controller also processes the analog signal to data indicative of the symbol during reading.

摘要： A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional or two-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edges of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.

摘要： An optical scan module, for example for an optical scanner, includes an integrally molded plastics material member which defines not only the laser focusing lens, but also the laser focusing aperture and the collection mirror. In addition, the molded member may act to house and to locate both a semiconductor laser and a photodetector, thereby ensuring easy and accurate placement of those elements within the scanning assembly. The optical assembly may be in modular form, mounted onto a common printed circuit board with a beam scanner.

摘要： According to a first aspect of the present invention there is provided an optical system for and a method of reading bar code symbols on a target by moving a laser beam directed toward the target in a scan across the symbol during a scan period that commences and ends at opposite scan end-limiting positions, respectively, of the scan. Power usage of the system is minimized by intermittently operating and energizing a light source during the scan period over a duty cycle prior to reading the symbol, to emit the laser beam for a working time period which is less than, and a fraction of, the scan period. The intermittent and cyclical nature of energizing the light source produces multiple images of the light beam on the symbol to visually enhance the aiming of a hand-held scanner at the symbol.

摘要： High speed scanning arrangements in scanners for reading bar code symbols by oscillating a scanner component in a single line pattern, the scanner assembly being suspended from a single flexural assembly for oscillating movement. The flexural assembly includes a flexure that lies in a plane extending through a central region of a scan mirror in a direction orthogonal to the plane of the mirror. A drive is operative for moving the scanner assembly from a rest position in a circumferential direction to one of two scan end positions. The flexural assembly is tensioned and stores energy, which energy is released in order to return the scanner assembly in the other circumferential direction to the other scan end position.

摘要： A scanning arrangement for use in an optical scanner, for example a bar code scanner, comprises an optical element which is mounted for oscillation in two directions to produce a two dimensional scanning pattern. The optical element is preferably relatively light, and is mounted for oscillatory motion in an x direction by the flexing of a spring of relatively high modulus of elasticity. The spring is secured to a mounting bracket which itself is mounted to a stationary frame by a further spring which is arranged to flex and cause oscillation in the y direction. The mounting bracket is relatively heavy in comparison with the mirror, and the second spring has a relatively low modulus of elasticity, thereby producing a y oscillation which is slower than the x oscillation.
