  • Patent number: 7854503
    Abstract: A recording apparatus has a recording head, a platen, and a first hole. The recording head includes a dot formation element array, and the platen holds a recording medium opposite the recording head. The first hole is disposed in an area of the platen opposite a downstream portion of the dot formation element array and guides ink discarded outside an end of the recording medium when the end is printed without a margin. Alternatively or additionally, a second hole is formed in an area of the platen opposite an upstream portion of the dot formation element array, and the platen guides ink, which is discarded outside an end of the recording medium when the end is printed without a margin, to the second hole.

  • Publication number: 20060203293
    Abstract: If a scanner and a desktop printer are stacked, the occupied space is reduced. However, in the printer unit below the scanner unit, the operationality such as feeding papers may be reduced and the access to the inside may not easy in doing maintenance. In the structure in which the scanner unit is fixedly placed on the top of the printer, the scanner printer multi-function apparatus has a sliding mechanism for sliding back and forth as means for connecting the scanner unit and a printer unit. Fixing positions are provided on at least two points back and forth. Each of the positions can be freely and easily selected. At the backward position, the scanner unit and the printer unit are stacked like a multitiered box so that the space occupied by the whole of the apparatus can be minimized, while at the forward position, the backward paper feeding opening is opened so that the operationality of the printer unit can be improved.
