<P>PROBLEM TO BE SOLVED: To provide a positional deviation correction device capable of preventing printing diffects due to skewed line caused by erroneous alignment of a line head in positional deviations in inkjet recording. <P>SOLUTION: A scan mirror 17 is set so as to maintain an optical path representing a maximum value of an output level of a light receiving section 21. After an alignment angle adjustment mechanism 13 is controlled so as to maintain the optical path to be in parallel to an arrangement line of a line head 7 for printing of K in a main scanning direction, each amount of positional deviation between each printing line of image information by a line head 9 for printing of C and a printing line of image information by the line head 7 for printing of K at both end sides in the main scanning direction is obtained, and then the controlling of the alignment angle adjustment mechanism 13 and the calculation of the amount of the positional deviation based on a detection output of an image detecting means is repeated so as to equalize both of the amounts of positional deviations. <P>COPYRIGHT: (C)2008,JPO&INPIT |
