Abstract

PURPOSE: To obtain automatically the pressure between separating roller brakes fitted for a sheet when the different sheet is employed by providing a detector for the tip of the sheet and a timer for the movement of the sheet on the paper-feeding device in the device for electrophotography and the like.
CONSTITUTION: A plurality of sheets 11 are separated by the separating roller 17 and the brake roller 18 one by one and the tip of the sheet 11 thus separated and fed is detected by a copy detector 27. Furthermore, after the start of paper-feeding is detected by detectors 30 and 31, a standard time required for the movement of the sheet 11 up to the point where the tip of the sheet 11 is detected by the copy detector 27 is set in the timer (not shown in the figure). And, based on a signal for expiration of time given by the timer, a solenoid 39 is driven to actuate an operating lever 35 and the roller brake consisting of a pawl wheel 34 and a fixed eccentric shaft 33. By this operation, the pressure between brakes can be adjusted automatically.
