ABSTRACT:
A device suitable for an electrophotographic copying machine which comprises a detection bar for detecting the transport of a copy paper and causing its pivotal movement by being pushed by the front side of the copy paper, a plurality of paper prevention claws responsive to the position of the detection bar for selectively allowing the transport of the copy paper and, otherwise, preventing the transport of the copy paper, and a rotatable shaft for coaxially coupling the detection bar with the paper prevention claws. According to the pivotal movement of the detecton bar, the rotatable shaft can be rotated to thereby rotate and lift the plurality of paper prevention claws.
