A scanner can read machine-readable code on an object. A scanner has a scanning device, a data device, and a registration device. The scanning device can repetitively scan the code and provide a scan signal repetitively corresponding to at least fragments of the code. The data device is coupled to the scanning device and responds to its scan signal for repetitively storing it. The registration device is coupled to the data device for reconstructing the code from at least two of the fragments of ...

A scanner utilizing an illuminating device, monochromatic light sources, and scanning elements to improve the color separation and reduce color crosstalk for generating chrominance component signals. The illumination device illuminates or transilluminates an image by means of the monochromatic light sources. The scanning elements converts the light obtained from the illuminated or transilluminated image into a chrominance component signal. The illumination device is implemented in such a way tha...

A scanner for optical coherence tomography for linear scanning of an object with electromagnetic radiation, in which the scanning direction runs transversely of the direction of propagation of the electromagnetic radiation, includes a deflecting element rotatable around a rotation axis that deflects the electromagnetic radiation, incident along a direction of incidence, toward the object and, by its rotation, effects the linear scanning of the object. A beam forming optics is arranged on the obj...

An efficient hand-held scanner simultaneously isolates and blocks out all but a single row of numbers on a lottery ticket at a time for ready comparison with winning lottery number displayed on the scanner. The multipurpose scanner has windows and displays for accommodating a six number weekly lottery game and a five number daily lotto game. The convenient scanner also has a support member, which preferably comprises an inclined flap, to support and guide lottery tickets past the windows of the ...

A scanner comprising a light source, having non-uniformities, for transmitting light through an input sample, and a cassette for holding the input sample, wherein a distance from the light source to the cassette is long enough to cause the effects of the non-uniformities to be substantially reduced.

To implement a high speed scanning, the positions in an image plane in the Y direction ("O") where no primary scanning is to be executed are removed. Only the positions in the Y direction ("1") where primary scanning is to be executed are stored in advance. On the other hand, the position in the Y direction which is currently being primary scanned is detected. Then, based on this result, the next position in the Y direction to be primary scanned ("1") is read from the stored information. The nex...

A scanner scans the scan subject by means of utilizing a rotative movement of a rotatable movable member for rotatably moving on a predetermined rotation axis. A scan mirror is supported by a single support axis. A rotary power of drive motors is converted into a reciprocating motion by crank mechanisms to rotatively move the scan mirror. A rotary angle of the scan mirror is detected by utilizing a principle of an interferometer.

A scanner is here disclosed in which the structure of an f.theta. lens can be simplified to decrease the cost of the scanner and facilitate the installation operation. In order to maintain the f.theta. properties, it is necessary to carry out control by prolonging a time interval of the radiation of light beams in the vicinity of the center of main scanning, and by shortening the time interval in the vicinity of the end portion of the main scanning so that the image formation spots of the light ...

A mirrorless scanner including a source of laser light producing a laser beam, a lens operative to receive the laser beam from the source of laser light and to direct it onto a target, and a vibrator coupled to the lens for vibrating the lens in at least two dimensions for causing the laser beam to scan across the target.
