Abstract: A portable scanning head emits and receives light from a light-emitting diode (10) to read symbols, such as bar-code symbols. The optics (12,18) within the scanner are operative for focusing a light beam (11) and the view of a light sensor (17) in different planes (13,22) exteriorly of a scanner housing. Imaging means are provided in the unit for imaging a viewing window. The viewing window has an area smaller than that of the scan spot. The system can employ an LED (10) as a light source and tolerate the relatively large-sized (on the order of millimeters) scan spot without sacrificing reading performance since the photodiode (17) "sees" only that portion of the scan spot visible through the viewing window.

Abstract: 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 massproduction techniques are also disclosed.

Abstract: A vertical slot scanner generates a full coverage scan pattern for reading symbols presented or moved past a vertical window. Scan lines are generated in upper and lower central regions of the window to improve scanner productivity.

Abstract: Scan lines are projected through a single horizontal window of a slot scanner and onto multiple surfaces of a product bearing a bar code symbol to be read. The symbol may be in any orientation and on any vertical surface of the product, as well as on the bottom surface of the product. Light from a light source 16 is reflected from a rotary mirrored component 26 and fixed mirrors 40-70.

Abstract: An optical scanner (30) has a scanner component mounted to a leaf spring (34) for oscillatory motion about an axis. An electromagnetic coil (58) and permanent magnet (56) cause a force to be applied to the scanner component away from a central, neutral position. Bending of the leaf spring provides a restoring force biasing the scanner component back towards the neutral position.

Abstract: A retro-reflective electro-optical scanner (10) has a laser diode (18) which directs a light beam onto an oscillating mirror (22). The light beam from the mirror impinges upon an indicia to be read, and the light is reflected back along a return path (26) to the mirror (22). After further reflection at the mirror, the light reaches a detector (24). With the present invention, the collection optics which are usually included in the light's return path are entirely eliminated.
