A stamp apparatus (1) having a conveying belt pair (2) for conveying a mail matter in an arrow T direction, a sensor (20) for detecting the conveyed mail matter, a stamp hub (4) which roll-contacts a postage stamp portion of the mail matter, rotates, and stamps the portion with a postmark, and a backup roller (10) for pressing the conveyed mail matter onto the stamp hub (4). The stamp hub (4) is directly connected to the AC servo motor (6), and is rotated at a speed equal to a conveying speed of the mail matter, when a effective region (3) contacts the mail matter. <IMAGE> |
