PROBLEM TO BE SOLVED: To correct feed shift generated when the leading end or bound part and rear end of a passbook penetrate into the nip between a pair of feed rollers or come out of the nip between them. SOLUTION: A passbook 2 having a bound part parallel to a printing figure direction, and a pair of feed rollers capable of holding the passbook 2 between a rotationally driven feed roller 4 and the freely rotatable pressure roller 3 brought into contact with the feed roller under pressure, are arranged before and behind a passbook printing part 7. The page discriminating data 20d preliminarily applied to the passbook 2 at every page is read before the passbook printing part 7 is fed, and individual correction valuesα,β,γ,δat the position where the leading end or bound part and rear end of the passbook 2 pass through the nip of a pair of the feed rollers are read from a correction value memory part 19a corresponding to the page discriminating data 20d to add correction to the quantity of rotation of a pair of the feed rollers at a time of the feed of the printing part.
