Printing unit

摘要

A first frame member (40) has an accommodating section adapted to accommodate a rolled sheet (90) at a rear side of the first frame member (40). A print head is operable to perform printing with respect to a part drawn out from the rolled sheet (90). A second frame (12) member is provided with the print head and supported on a front side of the first frame member (40) so as to be movable between a first position and a second position. A locking mechanism locks the second frame member at the first position. A release lever (13) releases the locked state of the second frame member (12) when the release lever (13) is pulled toward the second frame member (12). User access with respect to at least the accommodating section is allowed when the second frame member is placed in the second position.
