Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized electro-optic retroreflection scanning mode equipped with all necessary components and a completely built-in type. SOLUTION: This retroreflection scanning module is equipped with a base part, a 1st circuit board 416, and a 2nd circuit board 418 which is fitted almost at right angles to the 1st circuit board 416. The base part supports a light radiation body, which generates a scanning beam and an optical component which directs and converges light energy. A radiated beam reflection body reflects the light from a return mirror 212 on a reflection body fitted to a drive part for an oscillation body. The reflection body changes the direction of the beam to a mark to be read. The mark is scanned with the beam through the vibration of the reflection body. The reflected light is directed to the vibrating reflection body and made incident on a converging mirror 204, before reaching a detector 206. The detector 206 included in the module detects the light reflected from the mark scanned with the beam. The beam and the visual field of the detector 206 are scanned at the same time. Various implementation styles of vibration drive and optical arrangement are disclosed to make the scanning module small-sized.

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: MODULE OR ARRANGEMENT FOR, AND METHOD OF, READING A TARGET BY IMAGE CAPTURE WITH AN IMAGING READER HAVING OFFSET IMAGING AND AIMING SYSTEMS An imaging sensor of an imaging reader (30) senses return light from a target to be read by image capture along an imaging axis over a field of view that extends along mutually orthogonal, horizontal and vertical axes. Two aiming light assemblies (42, 44, 46) are offset from the sensor and are spaced apart along the horizontal axis at opposite sides of the sensor, and direct two aiming light lines, each having a predetermined brightness, at the target. The aiming lines are collinear along the horizontal axis and have inner linear end regions that overlap on the target to form a bright, linear, aiming mark having a brightness greater than the predetermined brightness to visually indicate a center zone of the field of view, as well as outer linear end regions that visually indicate approximate end limits of the field of view, over a range of working distances.

Abstract: A workstation (20) electro-optically reads targets by image capture, and includes a housing, a generally planar window (18), an imaging module, and a generally planar fold mirror (38) between the window and the module. The module has an illuminating light assembly for directing illumination light along an illumination path through the window at a target for return therefrom during reading, and an image sensing assembly for detecting return illumination light through the window along an imaging path over an imaging field of view (30) during reading. The fold mirror (18) folds the illumination and the imaging paths. The fold mirror (38) and the window (18) lie in planes that are substantially parallel to each other to prevent reflections of the illumination light off of the fold mirror (38) and the window (18) from entering the imaging field of view as virtual images that degrade target detection by the image sensing assembly.
