HOLE FORMING DEVICE IN CYLINDER INNER SURFACE SCANNING DEVICE

摘要

PURPOSE:To make the position of a punch unit changeable according to the dimension of a photosensitive material and to form a hole in a desired hole making position. CONSTITUTION:A photosensitive material is loaded in an inner side 3 and an input signal V4 for giving the dimension of the photosensitive material is inputted to a controller 49. When the controller 49 drives a pulse motor 9 by means of a control signal V1, its rotational force becomes one for moving a movable part 6 in a circular direction R by means of an engagement between a worm wheel 33 and a worm 34. Since a fixed part 7 is fixed to an end surface 2 by a bracket 22, the movable part 6 is rolled and guided in the circular direction R by a roller provided in its inner surface 26. When an original position detecting part 42 detects the passing of a blade part 44 following this movement, the controller 49 counts the pulse number of the control signal V1 and stops the driving of the pulse motor 9 when a counted value becomes equal to a counted value according to the input signal V4. At this time, punch units 4A to 4D are on specified hole position formed on the photosensitive material.
