本発明のＩｒ的は前記課題を解決した重送防止機構を提
供することにある。[Problems to be solved by optical IWJ] 1-The conventional paper transport mechanism section described above has problems with paper Ir(jM
Since it is not possible to sense the pt, there is a high possibility that ij L1 will be generated inside the printer if feeding occurs, resulting in printing being straggled and paper being wasted.Also, data will be lost. This has the disadvantage that it requires time to remove jammed paper, time to retransmit data, etc. 1. The purpose of the present invention is to provide a double feed prevention mechanism that solves the above problems.

Therefore, the IR feed stop roller operating mechanism 7 is notified of the occurrence of Ir+' feed, and the -

ある。Among the picked up sheets, 1 Jj of the sheets are fed by the rotating roller 11 and picked up by the roller 2. ;3 sends it to the developing section and performs normal operation - again. Stop 1: The paper that was being removed is transferred to roller 2 as the primary printing paper. :(When the paper is sent to By preventing jams inside the paper feeder, jams can be prevented from occurring.Also, by preventing jams, paper is not wasted, data is not lost, and jammed paper can be removed. It is expected that the time spent on making foil, data 11) transmission time, etc. will be reduced, and the operability will be improved! -There is.
