Technical Explanation for Code Readers/OCR CSM_CodeReder_TG_E_1_1 Introduction Sensors According to the definition by ANSI (American National Standards Institute), a barcode is a display of information in the form of bars (black portions) and spaces (area between the bars) of varying widths. Barcodes first emerged in the 1970s, and have come to be employed in a variety of different industries and applications, beginning with the fields of distribution and logistics. There are a number of varieties of barcodes such as the JAN/EAN codes, CODE128 which are used to manage barcodes for POS, and CODE39 which is used extensively in the industrial field ,and NW-7 which is used in distribution. These barcodes are all governed by ISO/IEC international standards. When the quality of the barcode printing is not good, the data may be read incorrectly, so it is important to take care in printing labels etc. Safety Components Features of Barcodes Highly flexibility due to its widespread use internationally Indespensible identification system for international transport, POS, etc. Great variety of models There are a variety of different readers, including the Pen model, Handy model, Stationary model, CCD model, laser model and camera model etc. High Speed Processing An effective tool for classification processes in high speed production lines etc. Visible Information By printing characters in addition to the barcode, it is possible to confirm information just by looking at it. Control Components Major Types and Application of Barcodes Type Numbers, alphabet, partially used symbols Widely used in industries Numbers, Stop codes (A to D) Symbols ( -,+,$,;,/,.)

Technical Explanation for Code Readers/OCR Barcodes require a great deal of space to express a lot of information, which means that they are difficult to use on small items and for stock control. For example, in the case of small goods for cell phones, these are generally in such high density packaging that barcode labels won't even fit. Also, since barcodes become difficult to read if they are dirty or damaged, a great deal of care need to be taken to maintain the quality of the printing. In order to solve these problems, the 2 dimensional code was developed which by expressing information...
