摘要： An automatic sheet feeding apparatus includes a sheet supporting device for supporting a sheet; an auxiliary roller for feeding a sheet supported on the sheet supporting device; a separating device, having a separation roller and a friction separation device, for feeding one-by-one the sheet; a feeder for feeding the sheet separated by the separating means; auxiliary roller moving device for moving the auxiliary roller between an operative position where the auxiliary roller is in contact with the sheet and an inoperative position where it is away therefrom; a separation roller moving device for moving the separation roller between an operative position where the separation roller is in contact with the friction separating device and an inoperative position where the separation roller is away therefrom; wherein the auxiliary roller moving device and the separation roller moving device move the auxiliary roller and the separation roller from their operative positions to inoperative positions after the feeder starts to feed the sheet separated by the separation roller.
