<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an image sheet, by which an image sheet having favorable storage property and easily having a photographic image and beautiful end edges can be easily and reliably manufactured. <P>SOLUTION: The method for manufacturing an image sheet includes using a cutting means for a laminated sheet material 200 by ultrasonic vibration as a cutting unit 50 to cut end sides 200c, 200d, 200e, 200f of the laminated sheet material 200. That is, the cutting unit 50 functions to transmit ultrasonic vibration from an ultrasonic vibration unit 51 to a blade 52 and to cause ultrasonic vibration at the blade top 52a, accompanied with the ultrasonic vibration of the blade 52, the blade top being in contact with a first sheet material that forms the surface layer of the laminated sheet material 200, and to generate frictional heat at the contact portion 53. The end side of the laminated sheet material 200 is cut while being heated and melted by the frictional heat. <P>COPYRIGHT: (C)2009,JPO&INPIT |
