Fraud prevention mechanism, paper leaf transport device, and paper leaf handling device

摘要

PROBLEM TO BE SOLVED: To solve a problem that an opening / closing member is illegally changed to an initial rotation posture while waiting for acceptance of a paper leaf while effectively preventing a deviation of a stop position of the opening / closing member. SOLUTION: An opening / closing member 50, a rotating member 70 that rotates integrally with the opening / closing member, a driving member 90 for driving the opening / closing member that is arranged facing the rotating member and is pivotally supported so as to be relatively rotatable, and a drive from the driving member. The drive transmission mechanism 100 includes a drive transmission mechanism 100 that transmits a force to the rotating member, and the drive transmission mechanism includes a driven piece 74 and a drive piece 92 that rotationally drives the rotating member by pressing the driven piece. A value that can prevent the value of the circumferential play θ3 between the drive piece and the drive piece from being rotated by an external operation to shift to the initial rotation posture when the opening / closing member is stopped in the non-initial rotation posture.
