Abstract: In a stamp apparatus, a paper-sheet object is conveyed in the arrow direction between a presser roller and an impress hub having a predetermined character/symbol string. Since a cam is rotated in the arrow direction by a rotary solenoid, it makes the presser roller approach the impress hub via a roller and an arm.
