  • Patent number: 9118830
    Abstract: A printer includes a scanner unit which reads a document; a recording portion which records information read by the scanner unit; and a tilt panel which constitutes the scanner unit and an operation portion of the recording portion. A printer executes a division reading mode which obtains image information of the entire document by linking image information obtained via a plurality of times of a document reading operation, with respect to the document of which the size is greater than the size of the document reading area. The image information of the entire document can be obtained by sequentially linking a predetermined image position of an ending position side of an image obtained by a first document reading operation and a predetermined image position of an initiating position side of an image obtained by the following document reading operation, in a linking direction of the image.

  • Patent number: 8899725
    Abstract: A cartridge mounting mechanism includes a chamber that accommodates therein a cartridge introduced through a cartridge inlet formed as an opening directed upward, a biasing mechanism that biases the cartridge set in the chamber in an upward direction corresponding to a removal direction of the cartridge, and a holding mechanism configured to be engaged with the cartridge so as to restrict, against a biasing force of the biasing mechanism, the cartridge from moving in the removal direction when the cartridge is set in the chamber, and disengaged from the cartridge to release the cartridge from the restriction against the biasing force, upon being subjected to an external operating force.

  • Patent number: 8573724
    Abstract: A recording apparatus includes: a recording head that performs recording on a recording target medium; a driving mechanism that is capable of causing the recording head to move closer to the recording target medium or move away from the recording target medium; and a controlling section that determines driving amount for one driving operation that is performed by the driving mechanism on the basis of results of a comparison made between a first recording head movement direction that is taken or to be taken in the one driving operation and a second recording head movement direction that was taken in another driving operation that is immediately before the one driving operation and thus precedes the one driving operation.
