摘要： The invention relates to an optoelectronic sensor, in particular a bar code reader, with an optical receiving system positioned in front of a light receiver for the deflection of a light beam reflected from an object, in particular a bar code, onto the light receiver. Through the provision of aperture diaphragms, or a plurality of light receivers, or regions with different image forming characteristics in the optical receiving system, a situation is achieved in which the receiving characteristics of the overall system, which result by reason of the shape of the sensing laser beam, as a result of the characteristics of the electronic evaluation system and as a result of different light intensities of the light returned, for example from a bar code, are optimized for different sensing distances.

摘要： The invention relates to an optical code reader comprising an optical scanning device (11) having a light transmitter (27) and a photoreceiver arrangement (19), said scanning device (11) transmitting a light beam (12) executing a scanning movement into a reading zone (14) provided at a reading distance ((L) from the scanning device (11). The reading zone preferably has a substantially planar front surface (13) and, moreover, a predetermined depth. Articles (16) carrying an optically detectable article code (15) are moved through the reading zone (14) and an electronic evaluation system (17), which is provided at the output of the scanning device (11), evaluates electrical signals formed by the photoreceiver arrangement (19) from the light reflected from the code (15) to the scanning device (11) and identifies the article code (15). A reflector (18) is arranged behind the reading zone (14) and, in the absence of an article (16) in the reading zone (14), reflects light received from the scanning device (11) in a manner identifiable as coming from the reflector (18) back to the scanning device (11). An article recognition stage (21) is provided in the electronic evaluation system (17), which suppresses the article identification until no further light is received which can be identified as coming from the reflector (18).

摘要： A rotary mirror arrangement (10) for changing the focus of an already focused laser beam is characterized in that a plurality of deflecting mirrors (12) of different focal length are secured on one side of a base plate (14) which is rotatably journalled on a stationary latch plate (16) arranged on the opposite side and can be latched with the latter in various rotational positions. In a respective latch position, a relevant deflecting mirror (12) is pivoted into the beam path of the incident light beam (LS). The base plate (14) is displaceably journalled on the latch plate (16) in the direction of the axis of rotation (A) and is held against the latch plate by spring force (18). The base plate (14) is supported by a three-point mounting on the latch plate (16) The mounting includes, in particular, three ball-segment-like projections (20) which cooperate with a conical bore (22), a wedge-shaped groove (24), or a lower disposed section (26) of the latch plate (16) or of the base plate (14) in order to unambiguously and reproducibly fix the base plate (14) in the respective latched position,

摘要： A method and an apparatus are described for the recognition and reading of a bar code provided on an object and consisting of a plurality of code elements. The object carrying the bar code is scanned by one or more scanning beams of a bar code reader, wherein each time a scanning beam sweeps over an object a scan is formed and bright and dark regions of an object swept over during a scan are recognized as scanned elements. A width index is determined for at least some of the elements scanned during a scan and is in each case representative for the width of the element in the scanning direction. Furthermore the frequency of occurrence of the width indexes found is in each case determined and a conclusion is drawn on the presence of a bar code from the frequencies that are found.

摘要： A method and an apparatus are set forth for the reading of a bar code consisting of a predetermined number of code elements in which a bar code reader which scans the code elements generates a binary signal with sequential high-low phases, the lengths of which correspond to the widths of the sequentially scanned code elements. Only those high-low phases whose lengths lie within a defined region are processed further as permissible code elements. Permissible code elements belonging to directly sequential high-low phases are respectively grouped into segments, and only those segments are processed further as being permissible which have at least the predetermined number of code elements. If the number of code elements of a permissible segment exceeds the predetermined number, the code elements which actually belong to the bar code to be found are determined by a start marking, a stop marking and/or a center marking contained in the segment and the bar code which has been found is decoded.

摘要： A bar code reader for an article (17) which is moved at least substantially in one direction (26) has a scanner (12) which generates a scanning light beam (11) which scans a surface (18) of the article (17) linewise, a light receiving arrangement (13) which includes an electronic evaluation circuit (14) with which bar codes (16) applied to the surface of the article (17) and scanned by the light beam (11) can be recognized and which is arranged outside of the parth of movement (20) of the article (17) and directed towards the front surface (18) of the article (17) as seen in the direction of movement. A detection means (27, 28) for the location of the scanning surface (18) at which the scanning is to start, and optionally a detection means (29) for the speed of movement of the article (17) are connected to an electronic control and evaluation circuit (14) which acts on an advance means ( 30, 31) for the displacement of the scanning line (23) in such a way that the spacing of the scanner (12) from the scanning line (23) on the surface (18) of the article (17) remains at least substantially the same.
