Abstract
A stamp apparatus having a conveying belt pair for conveying a mail matter in an arrow T direction, sensor for detecting the conveyed mail matter, a stamp hub which roll-contacts a postage stamp portion of the mail matter, rotates, and stamps the portion with a postmark, and a backup roller for pressing the conveyed mail matter onto the stamp hub. The stamp hub is directly connected to the AC servo motor, and is rotated at a speed equal to a conveying speed of the mail matter, when a effective region contacts the mail matter.
Claims13
A paper sheet stamp apparatus comprising:
- a conveying mechanism which conveys a paper sheet at a constant speed via a conveying path;
- a sensor which detects the conveyed paper sheet to acquire a stamp timing;
- a stamp hub which stamps a first surface of the paper sheet detected by the sensor;
- a backup roller which rotates in a rolling contact with a second surface of the paper sheet so as to press the first surface of the paper sheet onto the stamp hub;
- and
- a first driving portion which independently drives the stamp hub so as to rotate the stamp hub at the is constant speed, when at least the stamp hub contacts the paper sheet.

- a stamp hub which stamps a first surface of the paper sheet detected by the sensor;
- a backup roller which rotates in a rolling contact with a second surface of the paper sheet so as to press the first surface of the paper sheet onto the stamp hub;
- a first driving portion which accelerates the stamp hub so that the stamp hub reaches the constant speed until the paper sheet conveyed via the conveying path contacts the stamp hub and which decelerates and stops the accelerated stamp hub;
- and
- a clutch which interrupts a driving force transmitted to the stamp hub from the first driving portion to rotate the stamp hub following the paper sheet conveyed at the constant speed, when the stamp hub contacts the paper sheet.
