Claim 0:
1. An illegal-act detecting mechanism that detects that illegal-act means is attached to a paper sheet to be transported, comprising:
an opening/closing member that permits passage of the paper sheet at an initial rotation position, and blocks passage of the paper sheet at a non-initial rotation position deviated from the initial rotation position;
a rotary member that integrally rotates with the opening/closing member;
a driving member for driving the opening/closing member, which is arranged opposite to the rotary member and pivotally supported so as to be able to rotate relative to the rotary member; and
a drive transmission mechanism that transmits a driving force from the driving member to the rotary member, wherein
the drive transmission mechanism includes at least one driven piece provided in the rotary member, at least one driving piece that is provided in the driving member and intermittently drives and rotates the rotary member by pressing the driven piece directly or indirectly in a process of rotational transfer relative to the driven piece, and a buffer member that biases the driven piece and the driving piece in a direction away from each other.
