Abstract

PURPOSE: To facilitate unloading of a sheet tray or cassette by sensing the runout of copying material on the sheet tray or inside the cassette and releasing the contact of paper feed roller after sensing the runout.
CONSTITUTION: Holes 4, 32 for the detection of loaded copying material are provided on cassette 1 and intermediate plate 14 respectively. At the same time, a lamp 30 and a light-receiving element 31 are arranged in an opposed position at the lower part and the upper part of the cassette 1 respectively. In case copying material has run out, the light of lamp 30 incident into the light-receiving element 31 through detection holes 4, 32, exciting a solenoid 26 at sensing signal and releasing the contact of a roller 10 and a runner 7 with the cassette 1 and intermediate plate 14 through levers 9, 24. Thus, cassette can be unloaded smoothly without requiring manual strength.
