Abstract: In an imaging device for imaging a target, a photodetector with a two-dimensional light sensitive pixel area is provided. The two-dimensional light sensitive pixel area is divided into a plurality of split pixel areas. An imaging optics defines a plurality of segments of an FOV (field of view). The plurality of segments of the FOV respectively correspond to the plurality of split pixel areas of the photodetector. The imaging optics aligns, in a predetermined direction, the plurality of segments of the FOV to form a predetermined-direction oriented FOV so that the target is at least partially contained in the predetermined-direction oriented FOV.

Abstract: In an apparatus, a collimated-beam irradiating unit irradiates on the target a substantially collimated beam with a size thereon. A first pickup unit causes the photodetector to pick up through the imaging optics a first image of the target while the substantially collimated beam is being irradiated on the target by the collimated-beam irradiating unit. A measuring unit measures size information indicative of the size of the collimated beam being irradiated on the target based on the picked-up second image. A distance determining unit determines a distance between the apparatus and the target based on the measured size information of the collimated beam.

Abstract: An optical information readout apparatus is disclosed having an image forming optical section 4 operative to shift first and second lenses 24, 25 along an optical axis “O” at areas in front of a photodetector 3. A cylindrical body 23 incorporates a lens holder means, including permanent magnets 26 to 28, by which the first lens 24 is halted and held in any of positions a1, a2 and the second lens 24 is halted and held in any of positions b1, b2. Coils 31, 32, 75, 76 and a control circuit 16 drivingly shift the lenses. The control circuit is operative to independently move the lenses to change a focusing range of the image forming optical section in four different stages in the occurrence of a failure in reading out a two-dimensional code.

Abstract: In an apparatus for optically reading a graphic symbol composed of a plurality of optically identifiable unit sections of information, a first image pickup unit has a first photodetector and picks up a first optical image of the graphic symbol based on light detected by the first photodetector. A second image pickup unit has a second photodetector and configured to pick up a second optical image of the graphic symbol based on light detected by the second photodetector. A correcting unit corrects a light intensity level of at least one section of one of the first and second optical images based on a light intensity level of at least one section of the other of the first and second optical images. The at least one section corresponds to at least one of the unit sections of information of the graphic symbol.

The marker beam has a predetermined beam pattern indicating the reading position of the pickup unit.

Abstract: An optical reader having a reduced thickness due to an optical sensor configuration that is reduced in height compared to conventional optical sensor configurations. A sensor aperture in which the optical sensor is mounted and a lens-barrel aperture through which a lens-barrel that houses the reader optical imaging system is inserted are defined in a mounting substrate. The optical sensor is mounted in the sensor aperture so that a part thereof protrudes below the mounting substrate, and the lens-barrel is mounted in the lens-barrel aperture so that a part thereof protrudes below the mounting substrate. Because the optical sensor is disposed in the above manner, the space required above the mounting substrate to house the sensor is equal to the height of the optical sensor.

Abstract: An improved structure of an optical information code reader which is compact in size and may be manufactured at low costs. The code reader includes an optical mechanism disposed to define an optical path along which a return of light from an information code travels from a window formed in a reader body to an optical sensor. The optical mechanism including a plurality of reflecting mirrors arranged to reverse orientation of the optical path between the window and the optical sensor, thereby resulting in a decrease in length of the optical mechanism which allows the overall size of the code reader to be decreased. The reader body is so designed as to enable different types of optical units and different types of head covers to be mounted selectively, thereby allowing different types of code readers to be manufactured at low costs.
