  • Patent number: 9731429
    Abstract: A fixed blade support device includes a biasing member and a fixed blade support member (11). The fixed blade support member (11) includes a base surface portion (11a), an upright surface portion (11b), and a retainer portion (11c). The upright surface portion (11b) extends from the base surface portion (11a) in a biasing direction so as to close a rear side of a root portion of a fixed blade (12) on an opposite side to a blade edge portion thereof, and is configured to prevent the fixed blade (12) from being disengaged in a direction of engagement with a movable blade. The retainer portion (11c) extends from the upright surface portion (11b) so as to cover the root portion of the fixed blade (12), and is configured to prevent the fixed blade (12) from being disengaged in the biasing direction.

  • Patent number: 8882376
    Abstract: A plurality of ribs are provided on a cut paper discharge guide and an upper cover which define a discharge port for discharging a cut paper. The ribs hold a cut paper in width direction. Even if a cut paper having a high degree of curl is supplied when a roll diameter of a roll paper is reduced, it is possible to prevent a paper jam such as falling or clogging of the cut paper. It is desirable that the ribs provided on the cut paper discharge guide and the upper cover are disposed in an alternate pattern along the width direction of the discharge port. This arrangement is particularly effective in a printer having an inclined paper passage.

  • Patent number: 8662773
    Abstract: In order to cope with a change in design between a printer having a hip down design specification (first specification) and another printer having a hip up design specification (second specification), each of a lower frame and an upper frame has a structure common to both of the specifications. The lower frame and the upper frame are coupled to each other by a hinge structure removably attached to the lower frame and the upper frame. The hinge structure is selected from a first hinge structure and a second hinge structure. By changing the hinge structure from the first hinge structure to the second hinge structure and vice versa, the height of a hinge center can easily be changed.
