Patent

CA 2269061

This invention is a printer in which loading of print media (52) is greatly facilitated, and in which modular construction is used in order to substantially reduce the number of parts normally needed of this type of printer. The printer includes a base (10) and an associated cover (12) that encloses an interior region of the printer. The cover (12) is movable between opened and closed positions, and mounts a spring biased platen roller (40), which is engaged with a printhead (50) fixed in the base when the cover (12) is closed. A cutter mechanism (15), including a fixed blade (15a) mounted to the cover (12) and a reciprocating blade (15b) mounted in the base (10) also separates whenever the cover (12) is opened in order to further facilitate print media loading. The printhead (50) is secured to a printhead mounting and control module (54) which also includes components and circuitry needed to drive the printhead (50).

La présente invention concerne une imprimante dans laquelle le chargement de supports (52) d'impression est grandement facilité, et dont la forme modulaire permet de réduire sensiblement le nombre de pièces normalement utilisées dans ce type d'imprimante. L'imprimante comprend une base (10) et un couvercle (12) associé entourant une zone intérieure de l'imprimante. Le couvercle (12) est mobile entre des positions ouverte et fermée, et est monté sur un cylindre (40) sollicité par un ressort, qui vient en contact avec une tête d'impression (50) fixée lorsque le couvercle (12) est refermé. Un mécanisme (15) de coupe, comprenant une lame fixe (15a) montée sur le couvercle (12) et une lame à va-et-vient (15b) montée sur la base (10), se sépare également lorsque le couvercle (12) est ouvert afin de faciliter encore plus le chargement de supports d'impression. La tête d'impression (50) est fixée à un montage de tête d'impression et à un module (54) de commande comprenant également des composants et un ensemble de circuits nécessaires au fonctionnement de la tête d'impression (50).
