    • An apparatus and method for the recognition of codes has a light transmitter for the transmission of light signals in the direction of a scanning region, a light receiver for the reception of a light signal remitted from the scanning region, and a control and evaluation unit for the control of the light transmitter and the light receiver and for the determination of a code from the light signal received. The control and evaluation unit includes a trigger circuit triggering the determination of a code and a distance determination unit or image detection unit (which acts on the trigger circuit) for the detection of an object present in the scanning region which is integrated into the apparatus.

    • 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.
    • 用于至少基本上沿一个方向(26)移动的制品(17)的条形码读取器具有产生扫描物品(17)的表面(18)的扫描光束(11)的扫描仪(12) 一种光接收装置(13),其包括电子评估电路(14),利用该电子评估电路(14)将条形码(16)施加到制品(17)的表面并被光束(11)扫描,并且其是 布置在物品(17)的运动部分(20)的外侧并且朝向运动方向看的物品(17)的前表面(18)。 用于扫描开始位置的检测装置(27,28),以及用于物品(17)的移动速度的检测装置(29)连接到电子装置 控制和评估电路(14),其作用在用于使扫描线(23)移位的提前装置(30,31)上,使得扫描仪(12)与扫描线(23)的间隔在 制品(17)的表面(18)保持至少基本上相同。
