Abstract:
Disclosed is a printer including a paper feeder for accommodating a rolled paper to be pulled out and recorded thereon. The feeder has a container section to set the roll, in which first and second support walls are arranged to rotatably support the roll. While paper from the roll is taken out, a contact force produced by the roll against the first support wall is kept larger than that in a stationary state, and a contact force produced by the roll against second support wall is kept smaller than that in the stationary state. A friction coefficient between the second support wall and the roll is larger than one between first support wall and the roll, the roll being in slidable contact with the first and second support walls. Therefore, when the recording is started, an impact force to the roll can be alleviated, resulting in reducing unevenness in image in a feeding direction of the paper.
