Abstract

PURPOSE:To prevent the breakage or blur or a sealed character, by providing a mechanism for upwardly pushing a form roller above a carved seal in a return process after a sealing process is finished. CONSTITUTION:When a form roller passes a carved seal 2 to reach a turn-back point in a direction A, this state is confirmed by a sensor to drive a cylinder 9 and a form roller guide plate 5 is raised. The lowermost part of the roller 1 is made high by about 0.3mm from the upper surface of the carved seal 2. Thereafter, the form roller 1 moves while rotates in a direction C in a return process and the position thereof is confirmed by a sensor immediately before said roller 1 is brought into contact with an ink supply roller 12. Since the adhesion ink to the carved seal 2 is performed only in the forward process of the form roller 1, the ink adhered to the carved seal 2 is not again transferred to the form roller 1 and, therefore, the breakage or blur or the character sealed on IC can be prevented.
