Claims

[Claims for Utility Model Registration] (1) Image sensor means for sequentially reading image data line by line from an encoded image formed on a recording medium, and storing image data for each line read by the image sensor means. data storage means for determining whether the image data of the current line read by the image sensor means is equal to the image data of the previous line; and data determination means for determining whether the image data of the current line read by the image sensor means is equal to the image data of the previous line; The current one line of image data is not recorded in the data storage means, and only the current one line of image data that is determined to be unequal is recorded in the data storage means. A data reading device comprising: a data writing means for writing; and a data reading device. (2) The data writing means once writes the current one line of image data into the data storage means, and then reads out the current one line of image data and the previous one line of image data from the data storage means. The two are compared by the data discrimination means, and if the image data of the current line is equal to the image data of the previous line, the image data of the current line is written in the same area of the data storage means as the area where the image data of the current line is written. By writing the image data of the next input line, the previous one
2. The data reading device according to claim 1, wherein a current line of image data that is equal to the line and the image data is subsequently erased from said data storage means. (3) The data writing means has a 1-line buffer for storing the current 1 line of image data, and the data determining means determines that the image data in the 1-line buffer is equal to the image data of the previous 1 line. If it is determined that
2. The data reading device according to claim 1, wherein recording of the image data in the one-line buffer in the data storage means is prohibited, and the data is stored in the data storage means only when it is determined that they are not equal. .
