<p>PROBLEM TO BE SOLVED: To reduce gaps to be generated between blocks as a unit of exposure at the time of printing particularly by an LED head in an LED head driving unit. SOLUTION: LED chips are arranged in an array form, for example, in a plurality of blocks, a driving operation is executed per each block. A head controlling part 4 provides image data successively by the order of a block 14, a block 13, a block 12,... in the case of the right-upward correction so as to correct right-downward image data. On the contrary, it provides image data successively by the order of a block 1, a block 2, a block 3,... in the case of the right-downward correction so as to correct right-upward image data. According to the configuration, a printed image with little gap can be provided.</p> |
