PAPER GUIDE MECHANISM OF PRINTER

摘要

A printer is provided with a printer body that includes a paper roll holder; first and second paper guides that come in contact with both end surfaces of a paper roll in the paper roll holder and prevent a positional shift of the paper roll in a central axis direction; first and second guide rails that restrict movement directions of the first and second paper guides so as to allow the first and second paper guides to slide in the central axis direction of the paper roll; and a link lever that connects the first paper guide and the second paper guide. The link lever enables the first and second paper guides to slide in conjunction with each other and to move closer to or away from each other.
