したことを特徴とする紙の２重送り防止装置。To prevent double feeding of paper, paper is passed between a rotationally driven friction roller and a stopped friction member opposing it, and the paper is separated and fed out one by one. In the apparatus, the friction member is configured with friction pieces having two types of friction coefficients, high and low, so that they selectively occupy operating positions, and the paper to be passed is only one sheet. A device for preventing double feeding of paper, characterized in that the friction member is configured to switch from a high friction coefficient to a low friction coefficient according to the output of a sensor.
