Abstract
A separation unit (10) of a label printer includes a metal nip roller shaft (11), a resin nip roller (12) disposed at a center part of the nip roller shaft and is supported so as to be rotatable around the nip roller shaft, and resin supporters (13) that support both ends of the nip roller shaft. The separation unit (10) is attached to the body case (2) to be relatively movable between the normal ejection position and the separation ejection position. Each of the pair of supporters has a part protruding toward the nip roller, and this part is a roller holder (13d) to insert an end of the nip roller shaft. The roller holder and the supporter are integrally formed for enhanced strength of the supporter.
Claims18
A label printer, comprising:
- a housing including an opening;
- an opening and closing cover attached to the housing so as to open and close the housing;
- a feed roller rotatably supported on the opening and closing cover, the feed roller being configured to feed a print medium;
- a separation bar supported on the opening and closing cover and disposed in the vicinity of the feed roller;
- a print head disposed in the housing, the print head being disposed so as to be opposing the feed roller when the opening and closing cover is closed, the print head being configured to print on the print medium;
- and
- a separation mechanism disposed adjacent to the feed roller when printing on the print medium, wherein the separation mechanism includes:
- a pair of supporters opposing each other in a direction orthogonal to a feed direction of the print medium;
- a pair of roller holders each extending from an inner surface of a respective one of the pair of supporters in a direction orthogonal to the corresponding supporter, the direction being along which the pair of roller holders come closer to each other, each of the pair of roller holders being integrally formed with the corresponding supporter;
- a nip roller shaft having both ends each supported by a respective one of the pair of roller holders;
- and
- a nip roller supported on the nip roller shaft so as to be rotatable.
