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. Light is reflected from a scan mirror 50 to a rotating component 52 carrying mirrors 56,58,60,62. The light is then directed via a series of stationary mirrors 66,68,70,72,74,76 to the vertical window.

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.

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.
