  • Patent number: 6040919
    Abstract: A reading recording apparatus such as a facsimile apparatus is provided with a reading portion which causes an original conveying path to convey an original and reading image information, and a recording portion which causes a recording sheet conveying path to convey a recording sheet and effecting recording thereon, wherin an operating portion is disposed on the upper surface of an apparatus body, a lid member is provided openably and closably relative to the apparatus body, with the lid member, when in its closed position, covering the operating portion, and when in its opened position, supporting the original and the recording sheet so as to be guided by the original conveying path and the recording sheet conveying path, whereby the reading-recording apparatus has a well-balanced and compact structure.

  • Patent number: 5859653
    Abstract: A wheel for maintaining a constant distance between an ink discharge plane of a recording head and a recording sheet is provided on a carriage such that it is upstream of the recording head as viewed in the direction of movement of the recording head in a unidirectional print mode. A sensor monitors whether the recording sheet is moved off a contact of a feed roller which feeds the recording sheet to a record position and a pinch roller. Before a trailing edge of the recording sheet is moved off the contact of the feed roller and the pinch roller, bilateral recording is conducted to print in each of forward movement and backward movement of the carriage. When the sensor detects that the trailing edge of the recording sheet has been moved off the contact of the feed roller and the pinch roller, the recording is switched to unilateral printing. The print range at the trailing edge of the recording medium is thus extended.

  • Patent number: 5721581
    Abstract: A facsimile apparatus comprises a facsimile unit for sending data corresponding to image data that has been received, and a printer unit for performing image recording by discharging ink droplets in accordance with data sent from the facsimile unit. A first CPU for the control of the facsimile unit sends, after one page of image data, data in a predetermined pattern and further a paper exhausting command to the printer. A second CPU of the printer unit performs a paper exhausting operation upon receiving the paper exhausting command, after recording of the predetermined pattern, and upon conveying the recording paper up to a predetermined position, sends a signal for starting detection of the predetermined pattern to the first CPU. The first CPU thereby receives a detection signal from a photo sensor. The second CPU further conveys the recording paper, and at a timing of exhausting out of the apparatus, sends a signal for the detection end of the predetermined pattern to the first CPU.
