Title: Image recorder
Inventor: ONO TAKEHISA
IPC: G03B27/46
Filed: 2001-02-08
Abstract: PROBLEM TO BE SOLVED: To downsize the image recorder and to eliminate vertical flapping when a photosensitive material is drawn out of a magazine. SOLUTION: When the magazine 26 is removed from a loading section, width guides 40 are moved to the maximum width. When the next magazine 26 is loaded, photosensors 16 existing in the movable regions of the width guides 40 are drawn out until the front end of the photosensitive material A is detected by a drawing-out roller 36. When the front end of the photosensitive material A is detected, the photosensitive material A is wound back to the magazine 26 side to move the front end up to the outer side of the movable regions of the width guides 40. Next, the width guides 40 are moved up to the position where only the top and under surfaces at both ends in the transverse direction of the photosensitive material A are guided. The photosensitive material A does not exist in the movable regions when the width guides 40 move and therefore the jamming by dropping into grooves does not occur. Only the top and under surfaces at both ends in the transverse direction of the photosensitive material A are guided by the width guides 40, by which the vertical flapping of the photosensitive material A is eliminated.
