A page turning apparatus of a passbook printer, which detects a turning error or the like at the early stage of turning irrespective of the size and characteristics of passbooks and allows retry of turning in a short time. The apparatus includes: a passbook conveying path; a detecting device placed on the conveying path; storing means that stores a passbook holding position and a threshold value corresponding to a determined size; a page turning mechanism configured to buckle the paper of an turning target page and to turn the buckled paper at the passbook holding position; a buckling sensor that senses a buckling status; a conveying mechanism that can convey the passbook to a designated position on the conveying path; and control means configured to drive the conveying mechanism so that the passbook is conveyed to the passbook holding position, and drive the page turning mechanism to buckle the paper, wherein the control means, if the buckling status sensed by the buckling sensor indicates that the buckling extent does not reach over the threshold value within a predetermined time, determines that the buckling has failed and drives the conveying mechanism so that the passbook is conveyed from the passbook holding position to a revised position apart therefrom by a predetermined adjusting distance.
