A roll sheet feeding device comprising a sheet feed roller for feeding a roll sheet, and a stopping means for stopping said sheet feed roller at least one predetermined position, said means being provided in a midway of a passage through which a driving force is to be transmitted to said sheet feed roller, a diameter and an amount of rotation of said sheet feed roller is so determined that said sheet is fed for a predetermined length until said roller is stopped at a predetermined position after said sheet feed roller starts rotating from a predetermined position, and said stopping means being put into operation immediately before said sheet feed roller completes said amount of rotation, and said stopping means being interrupted said operation thereof at the time that said sheet feed roller completes said amount of rotation, whereby said sheet is cut by a predetermined length. This roll sheet feeding device has a simple construction and has little or no variation in length of cut sheet, even at a high sheet feeding speed. Two or more sheet lengths can be selected by selecting the diameter and the amount of rotation of the sheet feed roller in this roll sheet feeding device.
