PURPOSE:To enable working of titled filing holes without wrinkling recording paper by irradiating a laser beam to the part to be worked of the paper, and working the filing holes by the radiation heat energy thereof. CONSTITUTION:When recording paper 21 fixed by a fixing device 14 is brought to a prescribed position after a visible image is transferred thereon in a transfer part 12, a laser beam 17a generated from a laser beam generating source 17 is irradiated, via an optical fiber 19, to the end part of the paper 21. Filing holes 22 are worked by the radiation heat energy of the beam 17a. Wrinkling and oscillation of the paper 21 are thus obviated as a punch, etc. do not contact the paper. |
