Abstract

PURPOSE: To simplify the device in structure by shifting a movable element according to the motion of the cassette, by removing a light shielding number from the shielding location and by detecting the ray of a light which is radiated by a luminous body and reflected from the cassette.
CONSTITUTION: The cassette 1 is put into the device, and when the shifter 5a at the tip end of the cassette is moved from the position 5a' to the one 5a, the movable element 5 is simultaniously moved in the direction a. Accordingly the light shield 5b is also moved from the position 5b' to the one 5b, the reflected ray from the lamp 10, which has been cut off, is released and sensed by the phototransistor 11. By this, the fact that the cassette 1 is installed on a fixed location is detected. When all transfer paper has been fed and the intermediate plate 14 is exposed, the radiated ray passes through the aperture 15 and is not detected by the phototransistor 11, the fact that there is no paper is detected. In this way, since the detection is performed by only one detecting means, the device can be simplified in structure.
