PURPOSE:To leave no print of a registered seal completely on a form to prevent the seal from abuse by erasing the print of the seal when the registered seal is made useless after collating the print of the registering seal. CONSTITUTION:A seal-impression collation device 1 is provided with a writing head 2 for writing a seal to be reproduced on the form 6 and an erasing head 3. The paper 6 is a heat sensitive form, is discolored only at a heated part and supplied from a form feeding part 4 and wound around a form winding part 5. The erasing head 3 prevents the seal print reproduced on the paper 6 by the writing head 2 from the confirmation of the pattern. A part 7 in the figure is a visual field part for seal-impression collation. |
