摘要： 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 mass-production techniques are also disclosed.

摘要： A self-contained, portable data entry terminal positioned within a cordless, wand-type enclosure. Positioned within the enclosure is a bar code optical reader (12), signal conditioning electronics (14,15), a microprocessor (16), a memory (19), and a rechargable battery (22). The bar code optical reader is a sensor/emitter (12) that functions as both a sensor and an emitter to permit the readout of data stored in the memory (19).

摘要： This invention concerns an optical reader for bar codes characterized in that it comprises, located inside an enclosing housing (1), a linear motor provided with a guide rod (2) on which a moving coil (10) is slidably arranged which carries an objective lens (31) to which at least one illuminator (32) is connected for scanning a bar code provided on a card or the like which can be positioned on a fixed readout plane (35) by means of a guide slot (36) defined on said enclosing housing (1). Said objective lens is operatively connected to a detector (42) carried on a plate (40) which is connected to said moving coil (10).

摘要： Article indentification means are provided for sensing and deciphering signals emanating from, for example, labels such as barcode labels. The identification means includes sensing means (19) having a plurality of discrete sensing zones (21) each adapted to detect a portion or portions of the label (11). Deciphering means (20) are associated with the sensing means to decipher the label irrespective of alignment of the signal with the sensing means.

摘要： A scanner for mechanically distinguishing light from dark areas of an image, having a light source 3, a collecting lens 7 directing light from the source to surface 11 of a total internal reflective block 9. The top, parallel surface 13 reflects the light through a focusing, hemispherical condenser lens 17. Light reflected from area 21 on document 23 is collected by the center of lens 17, passes through a non-reflective surface 15 in block 9, and then through an objective lens 27, from which it is focused on phototransistor 29. The scanner functions well without precise positioning of document.

摘要： A reading apparatus for reading photoelectrically an original includes a light source unit having at least one fluorescent lamp, a CCD sensor for receiving a light which has been generated from the fluorescent lamp and reflected on the original, a monitor for monitoring an output signal from the CCD sensor, and a controller for controlling the CCD output signal to be at a predetermined level by changing the electric power supplied to the fluorescent lamp, thereby maintaining the temperature of the fluorescent lamp at a predetermined degree.

摘要： A compact laser scanner apparatus for use at a counter (22), such as a checkout counter, to produce a scanning pattern (34) thereabove and into which a bar code (26) can be inserted to enable the reading of the code, comprising a housing (30) having a top formed with a window (32) through which the scanning pattern is projected and indicia (202) for directing the location of the bar code (26) within the scanning pattern. The scanning pattern consists of first, second and third groups of scan lines which intersect one another in a common area to produce a star-burst pattern when projected on a plane disposed at approximately 45° to the plane of the window (32), while intersecting in approximately a triangular configuration when projected on a plane disposed approximately perpendicular to the window (32). The apparatus includes a laser tube (70), a rotating polygonal reflecting member (74) and plural beam folding mirrors (76) all disposed within the housing (30). Rotation of the reflecting member (74) causes the beam to sweep across the reflecting surfaces (76) which fold the beam and direct it out through the window (32) to create the pattern.

摘要： An optical scanner (10) that is particularly suitable for use in the optical system of a hand-held probe to conduct light to and from bar codes as they are. scanned or read for information. A lens (16) preferably integrally formed as a single piece fabricated of optical plastic by injection molding, includes three surfaces (18,20,22), one (18) of which in a preferred form is decentered with respect to the element optical axis (OA c ) and forms with another surface (20) an opposed pair used to control the output of a source (23) to illuminate bar codes. The remaining surface (22), the third, is prismatic, either converging or diverging as required, and is structured to cooperate with part of one of the paired opposed surfaces to conduct light reflected from a bar code to a small photodetector (28) for conversion to electrical form. Overcorrected spherical aberration is used to control the intensity, depth, and surface coverage of illumination so that the probe performance does not change for bar codes positioned anywhere throughout a predetermined working depth.

摘要： On effectue, dans un premier temps, un marquage en relief sur une surface du produit, et on effectue, dans un deuxième temps. une lecture sans contact du marquage :
- a) en émettant un plan lumineux (8a) obtenu par balayage laser dont l'intersection avec la surface marquée du produit se matérialise par une trace lumineuse (8b) croisant les reliefs de marquage (3),
- b) et en visant la zone marquée par des moyens optiques (9) sensibles à la lumière constitutive du plan luminuex et dont l'axe optique (11) est en dehors dudit plan, de manière à pouvoir mettre en évidence les décrochements de la trace lumineuse (8b) sur les reliefs de marquage (3) et permettre ainsi la lecture de celui-ci.
