Jam detecting device in a copying machine |
| 摘要 |
In a copying machine, a jam detecting device comprises jam detecting means operable in synchronism with movement of the photosensitive drum of the copying machine, and copy sheet discharge detecting means provided at an outlet for copy sheet. The two detecting means are positioned relative to each other so that T1 </= T2, where T1 is the time interval required for a copy sheet fed from its supply station to reach an outlet and T2 is the time interval measured from the time the copy sheet leaves the supply station till the jam detecting means is operated for a second time. When T1 is greater than T2, jamming of the copy sheet is detected.
