摘要： In an image forming apparatus, a carriage mounts a recording head for discharging droplets, and moves in a main scan direction. A guide member slidably guides the carriage. An encoder scale is arranged along the main scan direction. An encoder sensor reads the encoder scale. The carriage includes a head mounting part for mounting the recording head, and a sensor attaching part for attaching the encoder sensor.
The sensor attaching part is provided so as to be extended from the head mounting part. The encoder scale is arranged at a location which the encoder sensor can read. A partition member is provided to separate the head mounting part from the sensor attaching part in the carriage. The head mounting part is arranged in a first space, and the sensor attaching part and the encoder scale are arranged in a second space separated from the first space by the partition member.-

摘要： A recording apparatus includes a head unit including a recording head and configured to move between a recording position where recording is performed on a medium and a retraction position away from a medium transportation path; a movement mechanism that moves the head unit; and a positioning portion configured to position the head unit at the recording position. A moment for rotating the head unit is produced by a force applied by the movement mechanism to the head unit and by a reaction force received by the head unit from the positioning portion. A unit pusher configured to apply, to the head unit, a force acting in a direction of canceling rotation of the head unit when the head unit is located at the recording position pushes the head unit in a direction intersecting with a moving direction of the head unit.

摘要： Digital inkjet printing machine printing on cylindrical substrates, comprising a conveyor table conveying a cylindrical substrate and a printing station equipped with printheads having a parallel longitudinal axis. The table has a vertical rotation axis and supports a spindle supporting the cylindrical substrate. The spindle has an axis radially oriented with respect to the vertical rotation axis, and is actuatable in rotation about its axis. The conveyor table is configured to stop the spindle below the printheads, so the printheads have its axis parallel to the longitudinal axis of the printheads. The spindle axis stopped below the printheads belongs to main planes in which the printheads lie. The printheads are equidistant from the axis of the spindle. A first adjustment means adjusts the distance between the axis of the spindle and the printheads and a second adjustment means adjusts the orientation of the main planes in which the printheads lie.

摘要： A printing apparatus includes a medium support unit having a support surface that supports a medium. A position adjustment unit includes a plurality of position adjustment mechanisms that adjust a position of a support surface in an intersecting direction. The position adjustment unit can change an inclination of the support surface by some of the plurality of position adjustment mechanisms moving independently, and can change the position of the support surface in the intersecting direction by all of the plurality of position adjustment mechanisms moving in conjunction with each other.
