PROBLEM TO BE SOLVED: To properly keep a machine plate even under a state that a groove part is worked on a drum in an image drawing device, in which image drawing is performed onto the machine plate wound round the drum through the irradiation with laser beams. SOLUTION: A machine plate supporting device is arranged in the groove part. Further, elastic bodies for properly fixing the machine plate are arranged except just above the groove part onto the machine plate abutting surface, to which the ends of the machine plate are pressingly fixed, of a clamp. As a result, the machine plate does not sink in the groove part even when the side parts of the machine plate come to the groove part.
