摘要： This disclosure is directed to securing, with a simple structure, a head to a position in a carriage without having to fasten screws so as to prevent possible loss of a desired printing quality. A carriage is provided that includes a main housing mounted to a printing unit body, an eccentric cam rotatably disposed in the main housing, a sub housing that holds a head that ejects ink droplets. The sub housing makes contact with a cam face of the eccentric cam and is movable upward and downward relative to the main housing in response to rotation of the eccentric cam. The carriage further includes a rotation regulator that regulates rotation of the sub housing around a rotating shaft of the eccentric cam.

摘要： A controller 10 activates a heater 21 when a temperature detected by a temperature sensor 13 for detecting a temperature of ink becomes lower than a first reference temperature Ta lower than the appropriate ink ejection temperature Ta at the time of printing pause in which printing is paused. After the heater 21 is activated, when the temperature detected by the temperature sensor 13 exceeds a predetermined second reference temperature T2 that is higher than the first reference temperature T1 and lower than the appropriate ink ejection temperature Ta, the controller 10 moves the inkjet head to the maintenance region and forcibly discharges ink from the inkjet head in the maintenance region.

摘要： A printing apparatus is provided and includes cover members for covering at least a portion of a conveyance path for conveying a medium. The cover members are configured such that at least a portion of a part covering a conveyance path is able to expand and contract. Therefore, if necessary, it is possible to expand or contract the area of the cover members covering the conveyance path. On the occasion of setting the medium or when a jam has occurred, it is possible to contract the cover members in the conveyance direction of the medium. Also, even if the cover members move once from the state where they cover the conveyance path, it is possible to easily return the cover members to their original positions, and it is possible to easily return the cover members to the state where they cover a portion of the conveyance path.

摘要： A tension applying member of an inkjet printer can apply tension on a printing medium by pushing a portion of the printing medium that is not wound by a winding mechanism by its own weight in a rotating direction indicated with an arrow having an axis line as a center; a transport controller causes a motor to generate a power for winding the printing medium when a predetermined tension is no longer applied on the printing medium by the tension applying member; and the winding mechanism limits a torque with a torque limiter and applies a predetermined tension on the printing medium when the motor is caused to generate the power for winding the printing medium when the predetermined tension is no longer applied on the printing medium by the tension applying member.

摘要： An adjustment mechanism is structured to adjust and fix a liquid discharge head in position on a base plate. The adjustment mechanism includes a first plate, a second plate, a pivotable cam, and a first biasing unit. The first plate is changeable in position in a circumferential direction relative to the base plate. The first plate is fixed to the base plate. The second plate is mounted on the first plate movably relative to the first plate in a direction different from the circumferential direction. The liquid discharge head is fixed to the second plate. A first biasing unit biases the second plate toward the pivotable cam in a horizontal direction to prevent the second plate from lifting upward off the first plate. The pivotable cam is operable to move the second plate against an biasing force of the first biasing unit and to locate the second plate.
