  • Printing apparatus with cover actuated drive source
    Patent number: 6155731
    Abstract: A printer in which loading of print media is greatly facilitated and in which modular construction is used in order to substantially reduce the number of parts normally needed for this type of printer. The printer includes a base and an associated cover that encloses an interior region of the printer. The cover is movable between opened and closed positions and mounts a spring biased platen roller which is engageable with a printhead fixed in the base, when the cover is closed. A cutter mechanism, including a fixed blade mounted to the cover and a reciprocating blade mounted in the base also separates whenever the cover is opened in order to further facilitate print media loading. The printhead is secured to a printhead mounting and control module which also includes componentry and circuitry needed to drive the printhead.
