Scanning apparatus in which a sensor is mounted within a transceiver casing and a single focusing means both forms a beam from a radiation source for delivery to a target and focuses a returned beam onto the sensor. A forward looking reflective surface is included in the path of one of the beams, causing that beam to be twice passed through the focusing means. The sensor faces the radiation source, thus avoiding the need for a separate lens for the returned radiation. The scanner is particularly...

An aerial vehicle rotating in gyroscopic fashion about one of its axes having an optical system operative to scan an area below the vehicle in determined relation to vehicle rotation. A sensing device is provided to sense the physical condition of the area of scan and optical means are associated therewith to direct the physical intelligence received from the scan area to the sensing means. Means are provided to incrementally move the optical means through a series of steps to effect sequential ...

A scanner includes a sensor rack carrying a sensor, and a guide rod adapted to guide reciprocating movement of the sensor rack, the sensor rack having a guide frame disposed at a bottom side thereof in contact with the guide rod, the guide frame having a double-bevel bottom sidewall formed of two bevel surfaces, which are respectively disposed in contact with the guide rod.

A scanner for the detection of one-dimensional and/or two-dimensional codes has a light receiver arranged in a housing and an optical receiving system associated therewith and also accommodated in the housing. At least one light source is additionally provided in the housing to illuminate the region to be scanned arranged in a scanning plane. At least one of the light source and the optical receiving system is movable in order to allow a reading distance between the housing and the object plane ...

A scanner. The scanner comprises a mask, a document holder and a controller. The mask has a sensor disposed on the surface thereof. The document holder has a identification portion disposed on the surface thereof. The sensor detects the identification portion and sends an identification signal to the controller. The controller determines a document type and directs the scanner to scan the document according to the identification signal.

A scanner is disclosed which uses an electro-optic deflector to deflect a light beam onto a receiving medium. The deflector comprises a substrate formed of an optical material and a thin film optical waveguide fabricated on a top surface thereof. An array of parallel metallic electrodes are formed on the waveguide. Each of the electrodes is adapted to receive a voltage independently of the other electrodes. When a voltage is supplied to an electrode, a spatial variation in the index of refractio...

The scanner has a body having a scanning unit, a display device, a keypad, a holding member holding together the display and the keypad, a mounting structure for mounting the holding member to the body, and a cable holder having a holding part for holding a plurality of cables and arranged in a floating state at one of the keypad and the display. The cable holder has two side walls and a bottom wall, with grooves at the tops of the side walls. Cables are arranged in the grooves and pressed by a ...

A laser radar device that operates on an elapsed time basis and has a pulsating laser for emitting successive light pulses into a monitored region. A light receiver receives light impulses reflected by an object in the monitored region and generates electrical signals responsive to the received light impulses. The signals are forwarded to an evaluation unit adapted to generate a distance signal indicative of a distance between the object and the laser radar device on the basis of the speed of li...

A scanner, including a contact image sensor module and an elasticity-providing element, is provided. When scanning, the elasticity-providing element is capable of avoiding vertical shift of contact image sensor module resulting from mechanical friction or other unexpected. Therefore, the contact image sensor module can retrieve clear images all the time.

When the scanner moves over the subject copy, the first reading elements of a close contact type image sensor (1) read the copy. As the movement causes a platen roller (5) to rotate, an encoder ring (4), having a prescribed distinguishing pattern (10) printed within, rotates. Second reading elements configured outside the copy reading range of the close contact type image sensor (1) read the distinguishing pattern, which moves over the reading face as the encoder ring (4) rotates. The second rea...
