Carriage-retarder Mechanism Patents (Class 400/337)
  • Patent number: 7632030
    Abstract: A recording apparatus includes: a carriage having a recording head, a movement unit that reciprocally moves the carriage, a carriage detection unit, a point-of-origin detection unit that detects the position of a point of origin of the carriage, a regulation unit capable of restricting the movement of the carriage, and a control unit that selectably performs one of a first initialization processing and a second initialization processing longer in time than the first initialization processing. The control unit selects one of the first initialization processing and the second initialization processing on the basis of whether movement of the carriage is restricted and whether a travel distance of the carriage corresponds to a predetermined distance, when the movement unit moves the carriage from a position of origin toward the regulation unit.

  • Patent number: 7572076
    Abstract: A printer includes a printing part that prints inputted printing information on paper while moving by gravity and supports that support the printing part and the printing medium facing each other so that the printing part is movable in the gravity direction. The printing part corrects the inputted printing information according to a moving distance and a moving speed of the printing part and prints corrected printing information on the printing medium.

  • Patent number: 5199804
    Abstract: An improved quiet impact printer mechanism for use with a typewriter or printer which includes a print hammer having a significant mass for impacting a character pad against an ink ribbon, paper and a platen. A first embodiment has a drive means providing insignificant inertia through the use of a cam driven by an inexpensive, low torque reversible motor which is coupled to the hammer through a cam follower. The cam arrangement may also propel the hammer toward the platen under a predetermined series of controlled velocities. A second embodiment of a printer mechanism, similar to that described above, includes a rotary member driven by a motor link, coupled to the print hammer for moving the hammer toward and away from the platen. The motor link includes an acoustic noise reducing means.
