To prevent recording quality from deteriorating because an end position of recording paper is detected in a displaced state, by carrying the recording paper at a high speed so as to make recording, in a recorder which is equipped with a paper detector for detecting the recording paper by the engagement of a movable mechanism part with the recording paper.
Time for a lever 631 to turn from a turning position, indicated by a sign 631b, to a turning position, indicated by a sign 631c, after an end of the recording paper P is disengaged from the lever 631 is detection delay time in the detection of the end of the recording paper P. A detection delay error carrying amount can be calculated by the following equation, y=αx (1), in which x represents the carrying speed of the recording paper P, in which y represents the detection delay error carrying amount, and in which αrepresents a delay coefficient and serves as a preset value varying according to each of the recorders. The end position of the recording paper P is corrected by the calculated detection delay error carrying amount.
