To provide a paper feeder capable of normally feeding rolled paper without removing it from the paper feeder even when the rolled paper is set in any direction.

A guide roller 10 is movably provided in response to the setting form of the rolled paper 2 and when the rolled paper 1 is set to the first form, the guide roller 10 is positioned at a position opposite to a draw-out direction of a recording paper 2a and a support member 3 is rotated in an arrow A direction to feed the recording paper 2a (a). When the rolled paper 2 is set to the second form, the guide roller 10 is moved onto the recording paper 2a and a rotation direction of the support member 3 is switched to an arrow A' direction interlocking with movement of the guide roller 10 (b). Thereby, the recording paper 2a can be smoothly fed regardless of the set form of the rolled paper 2.
