PROBLEM TO BE SOLVED: To provide a punch device which is annexed to an image processor, drills a punch hole in a sensitive material, retracts up to a proper position at the time other than hole drilling so that it does not obstruct mounting of the sensitive material, prevents the sensitive material from bending due to the operation of a punch pin, and can drill a hole substantially at a fixed position at all times. SOLUTION: A punch pin 25 is supported so as to travel freely in the radial direction of drum 6 for processing a picture image by a solenoid 27 on a support block 22 moving freely in the direction orthogonal to the direction of feed of a sensitive material for original plate by a solenoid 23. A female edge 28 is formed on a sensitive material hold face 6a of the drum 6 for processing the picture image that the punch pin 25 faces by moving the support block 22. At the time of drilling hole, the solenoid 23 is operated to position the punch pin 25 at a position opposing to the female edge 28 and operate the solenoid 27. When the picture image is formed, the support block 22 is moved to retract the punch pin 25 from the sensitive material hold face 6a. |
