Claims

[Claims for Utility Model Registration] (1) An image sensor means for reading image data from a coded image on a recording medium, and a device for writing the image data read by the image sensor means and for storing the image data. data storage means; free space determination means for determining whether or not there is free space left in the data storage means when image data is being written to the data storage means; a data write interrupting means for interrupting writing of image data to the data storage means when it is determined that there is no free space in the data storage means, or that there is no free space; Free area generating means for decoding the image data written in the data storage means and generating a free area in the data storage means when writing of image data to the data storage means is interrupted; A data reading device comprising: data write restart means for restarting writing of subsequent image data to the data storage means when a free area is generated in the data storage means by the means. (2) image sensor means having a running means capable of sudden stopping and capable of running on a coded image formed on a recording medium, and reading image data from the coded image while running; A data storage means for storing the image data read by the sensor means while the sensor is running; and a data storage means for storing the image data; a free space determining means for determining whether or not an area remains; and when the free space determining means determines that there is no free space in the data storage means, or that there is almost no free space in the data storage means; data writing interrupting and image sensor running stopping means for interrupting writing of image data and stopping running of the image sensor; and data writing interrupting and image sensor running stopping means for writing image data into the data storage means. a free space generating means for decoding the image data written in the data storage means when writing is interrupted, and generating a free space in the data storage means; Data writing restart and image sensor running restart means for restarting writing of subsequent image data into the data storage means and restarting running of the image sensor means when a free area is generated in the data storage means; The data reading device according to claim 1, characterized in that:
