<p>PURPOSE:To prevent insufficient supply of image receiving mediums by providing a housing in which the image receiving mediums are stacked and stored, a movable plate disposed confronting the housing and displaced as the number of the image receiving mediums decreases and a detecting mechanism for detecting a predetermined displacement of the movable plate. CONSTITUTION:A shortage of the remaining amount of image receiving sheets C stored in a cassette 56 is always checked by an arm member 78 and a detecting section 84 which constitute a detecting mechanism. When the image receiving sheets C are fed out one by one by a paper feed roller 98 so as to decrease the number thereof, a movable plate 62 is rotated in the direction (a) by means of conical coil springs 66a, 66b, and therefore, it is gradually elevated. In this arrangement, one end part of the arm member 78 abuts against a reed 68 formed on one side part of the movable plate 62, and therefore, the arm member 78 is rotated in the direction (b) as the movable plate 62 is elevated. When the arm member 78 is rotated by a predetermined angle, the other end part of the arm member 78 is detected by the detecting section 84 which therefore detects a shortage of the remaining amount of the image receiving sheets C. Further, an instruction for stopping the supply of a photosensitive material A is delivered to a photosensitive material supply section 13.</p> |
