ータ読取り装置。[Claims for Utility Model Registration] (1) Image sensor means for reading image data from a coded image formed on a recording medium; data storage means for storing the image data read by the image sensor means; A data reading device comprising: unnecessary data removing means for detecting unnecessary data from among the image data read by the image sensor means and preventing the unnecessary data from being stored in the data storage means. (2) The encoded image has a series of black cells on both sides, and the unnecessary data removal means is an unnecessary data removal circuit equipped with a D flip-flop, and after the image sensor means starts main scanning. . characterized in that when a signal corresponding to the first detected series of black cells is input to the D flip-flop, the black cells and the image data following the black cells are stored in the data storage means. Item 1. The data reading device according to item 1. (3) the encoded image has a series of black cells on both sides, and the unnecessary data removal means specifies the last address of one main scanning line of image data stored in the data storage means; and address decrement means for decrementing the last address; black cell detection means for detecting the first black cell when the last address designation is decremented by the address decrement means; and the black cell detection means for detecting the first black cell. and address storage means for storing the address of the black cell detected by the detection means, and the address stored by the address storage means is stored in the data storage means for image data of the next main scanning line. 2. The data reading device according to claim 1, wherein the first address is the first address. (4) The unnecessary data removal means includes encoded image width detection means for detecting the width of the encoded image, and within the width detected by the encoded image width detection means, the image sensor 2. The data reading device according to claim 1, wherein the image data read by the means is stored in the data storage means.
