PROBLEM TO BE SOLVED: To freely mount a plurality of paper rolls having different diameters in an unused (new) state according to a choice of a user, and to increase convenience for the user. SOLUTION: A paper feeding device 3 for feeding a paper roll 2a (2b) to a printing device 4, includes two side plates 8b vertically arranged along both sides of the paper roll 2a (2b). The side plates 8b are provided with a plurality of notches 11, 13 capable of bearing-supporting the paper rolls 2a (2b) having the different diameters in the unused state. When the notches 11, 13 are mounted with the corresponding paper rolls 2a (2b) in the unused state, end portions 14, 15 of outer peripheral surfaces of the paper rolls 2a (2b) on the printing device 4 side are arranged to be positioned in the substantially the same vertical plane.
