Abstract:
PROBLEM TO BE SOLVED: To reduce the size and the weight of a component used for collection of reflected light by providing an integrated optical element, which includes a beam forming part and beam bending part made one-piece and a light collection part which collects reflected light to lead it to a detector, to scan and move a light beam. SOLUTION: A light beam 16 from a semiconductor laser 18 passes through a plastic lens 20 and is turned at 90 deg. by total reflection in a prism 22. It is emitted from the prism 22 and passes through an aperture 24 in a collection mirror 26 and strikes on an oscillatory scanning mirror 28. Then, an exit light beam 30 for scanning is generated and is led to indicia to be read. Reflected light 32 from a mark is first received by the oscillatory scanning mirror 28, and this mirror 28 leads it to a concave 34 of the collection mirror 26. The concave 34 focuses light on a photo detector 40 through an aperture 36 and a filter 38. The output signal of the photo detector 40 is supplied to proper electronics in a printed circuit board 14 by electric coupling 42.
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:
PURPOSE: To provide a highly practical and reliable and inexpensive hand-carry type scanning device for using a non-laser light source without errors. CONSTITUTION: A light beam is radiated from a light emitting diode so as to read a symbol, a bar code symbol for instance, and reflected light returned from the symbol is received. An optical system inside this scanning device converges the visual field of the light beam 11 and a photosensor 17 to different two planes present at the outside of a housing. A device for image-forming a vision checking window is installed inside the scanning device and the area of the vision checking window is smaller than the one of a scanning spot. The scanning device uses the light emitting diode (LED) 10 as the light source, and since the LED 10 views only the part of the scanning spot viewable through the vision checking window, the scanning spot of the relatively large size (about several millimeters) of the LED 10 is used without sacrificing read performance.

PROBLEM TO BE SOLVED: To project scan lines on multiple surfaces of a product passing through a horizontal slot scanner having a single horizontal window. SOLUTION: The scan lines are projected through the single horizontal window of the slot scanner and onto multiple surfaces of a product with a bar code symbol to be electro-optically read. The symbol may be on any vertical surface of the product, as well as in any orientation on the bottom surface of the product. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To generate an omni-directional scan pattern having high scan line density without dead zones, especially in the upper part and the lower part of a vertical window. SOLUTION: A vertical slot scanner generates a full coverage scan pattern for reading symbols presented or moved over a vertical window. Scan lines are generated in upper and lower central regions of the window to improve scanner productivity. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide an inexpensive and rugged scanner which can be easily replaced with another by preparing an optical module and a PCB(printed circuit board) having a stationary electric connector, which is attachably connected to a coupler that electrically connects the optical module fixed to the PCB to the PCB. SOLUTION: An optical module and a PCB 212 are prepared. The optical module includes an optical scanner 206 which scans a mark to be read, an optical detector which detects the light reflected from the mark that is currently read and also supplies the data signal shown by the mark and a movable electric coupler. The PCB 212 has a stationary electric connector which is attachably connected to a coupler that is fixed to the PCB 212 and electrically connects the optical module to the PCB 212, and contains an electric circuit fixed to the PCB 212 for control of the optical module. The electric circuit prepared on the PCB 212 includes a drive device that drives the scanner 206.

Abstract:
The disclosure relates to systems and techniques for reading optical codes, and more particularly to code reading systems with plural imaging or scanning modules pointed in various directions toward a target volume, which increase the likelihood that a code symbol on an arbitrarily oriented object in the target volume will be read. Other aspects of the invention relate to use and configuration of hand held readers, docking devices, operator side rails, arched tunnels and mirrors for increasing the coverage of the system. Additional aspects of the invention relate to components associated with point of sale installations or code reading terminals including integrated scales, input pads, system controls and displays.
