Abstract
A sheet jamming-proof mechanism for a paper-feeding system provided outside of a left and a right paper boundaries delimited along a predetermined paper-feeding pathway to supervise the paper-feeding direction for preventing sheet jamming. The sheet jamming-proof mechanism includes: a plurality of touch plates, each touch plate being closely contiguous to the outside of the left or right boundary of paper-feeding pathway and being elastically hold by the paper-feeding system so that the touch plate is forced to shift when the contact plate is pressed by a deviated paper; a plurality of detectors, each detector locates in the vicinity of the touch plate to sense the shift of the touch plate; and a controller which controls the driving device of the paper-feeding system to alter the ordinary paper-feeding operation for preventing sheet jamming when shift of any touch plate is sensed by the detectors.
