  The roll guide mechanism 20 is provided with a pair of roll guides 22 and 24 which can be rotated by sandwiching a roll 12 (see FIG. 3) in which the label continuous body is wound in a roll shape from both side surfaces.

  The pair of roll guides 22 and 24 of the roll guide mechanism 20 are provided with a pair of racks 30 and 30, and the racks 30 and 30 have their front end portions always overlapped at intervals. In this overlapping portion, a pinion 32 that is engaged with both racks 30 and 30 is disposed. The pinion 32 is rotatably mounted, so that when one roll guide is slid in an arbitrary direction, the other roll guide is in a direction opposite to the sliding direction of the one roll guide. And is slid by a distance equal to the sliding amount of one of the roll guides 22 and 24.

  By this rack and pinion mechanism, the pair of roll guides 22 and 24 can be moved relative to each other in the direction of approaching and separating from each other while maintaining a parallel state, so that the roll 12 can be sandwiched from both sides and the roll 12 can be rotated. It can be movable.

  The printer main body 60 is provided with an upper cover 70 that can be opened and closed with the rear side as a fulcrum, and has a thermal head 68 provided on one end side of the upper cover 70.
