  • Patent number: 8029086
    Abstract: A printing device includes first and second print heads, first and second print head control units, a first print head feeding unit moving the first print head in a main scanning direction, a second print head feeding unit moving the second print head in the main scanning direction, a first medium feeding unit moving a first medium holding unit in an auxiliary scanning direction orthogonal to the main scanning direction, a second medium feeding unit moving a second medium holding unit in the auxiliary scanning direction in parallel with the movement of the first medium feeding unit, a first printing unit control unit (controlling the first print head control unit, the first print head feeding unit and the first medium feeding unit), and a second printing unit control unit (controlling the second print head control unit, the second print head feeding unit and the second medium feeding unit).

  • Patent number: 6959977
    Abstract: There is provided an inkjet printing device, which is provided with an inkjet head and an ejection restoring system. The ejection restoring system includes a sucking device, a sucking device moving mechanism, a wiping member, a wiping member moving mechanism, and a driving system that drives the sucking device and the wiping member through the sucking device moving mechanism and the wiping member moving mechanism so that one of the sucking device and the wiping member is not driven if the sucking device and the wiping member interfere with each other. The driving system includes a first position detecting system that outputs a first state signal indicating that the sucking device and the wiping member interfere with each other and outputs a second state signal indicating that the sucking device and the wiping member do not interfere with each other, and a controller that controls at least one of the sucking device and the wiping member based on an output of the first position detecting system.
