To prevent a strip of recording paper unreeled out of a machine grazed paper holder from being directed obliquely.

A machine grazed paper holder 6B includes on its lower cover 6-1 a leading guide part 10 that leads a strip of recording paper P2 unreeled from a machine grazed paper P1 above the centerline of the holder 6B and above an insertion opening 4 made in a printer main body 1. The leading guide part 10 extends parallel to the holder centerline. The strip of recording paper P2 is folded back at the upper end of the leading guide part 10 and then inserted into the insertion opening 4. If the machine grazed paper P1 leans about in the holder 6B, the leading guide part 10 corrects the obliquity of the strip of recording paper P2 across the holder centerline.
