Abstract
PURPOSE:To correct the position of record starting exactly and easily without using complicated regulating mechanisms by a method in which the divergence of the record starting position for each head is detected and on the basis of the detected diverged amount, record starting time for each head is controlled. CONSTITUTION:The photosensor 10 of each head is actuated by a record starting position check signal mode (e) and 40 lines record end signal (f), and at the same time a devergence detector 3 is operated. That is, the distance from the boundary line position SP of a paper guide plate to the record starting position of head is counted by a counter 15a on the basis of clock, and the value obtained is compared with a preset reference value at an arithmetic circuit 16a and its difference signal (r) 10a is sent to a divergence corrector 4 as a diverged amount. In the same way, diverged amount is detected at all heads. At the corrector 4, the diverged amount of each head is converted into time amount and then the record starting time of each head is controlled by the controller 5.
