  • Publication number: 20150022609
    Abstract: A printing apparatus includes a housing, a carriage in which a print head is mounted, the carriage moving inside the housing, and an openable cover provided for the housing. A restricting member configured to restrict movement of the carriage during transport of the printing apparatus is attachable to the printing apparatus. While the restricting member is attached to the apparatus, the restricting member engages with the carriage, the cover in a closed position, and the housing and part of the restricting member is exposed outside of the cover in the closed position. When the part is pulled, the restricting member disengages from the carriage, the cover, and the housing and is detached from the apparatus.

  • Patent number: 7594720
    Abstract: A recording apparatus, in which a recording medium is fed from one side of the recording apparatus, and the recording medium that has been recorded is ejected from the one side of the recording apparatus, is capable of making its size when not in use smaller than the size when in use and also achieving a reduction in the depth dimension of the recording apparatus as compared with the case where a feed tray and a discharge tray are rotary storage trays. The recording apparatus includes a feed tray on which a recording medium is stacked and which is rotated to move between an in-use position and a stowed position, and an eject tray on which the recording medium that has been recorded is stacked and which moves between an in-use position and a stowed position in a discharge direction of the recording medium.
