One segment recording head among the 12 segment recording heads is selected as a reference head. The segment recording heads other than the reference head among the 12 segment recording heads are arranged such that longitudinal directions of the segment recording heads other than the reference head are parallel to a longitudinal direction of the reference head. The head base is arranged such that the longitudinal direction of the reference head is orthogonal to a conveyance direction of the paper.

Inkjet recording apparatus and recording head position adjustment method

An inkjet recording apparatus includes a first storage part, a second storage part, an ejection part, a first supply path, a regulation part, and a second supply path. The second storage part is provided higher than the first storage part. The ejection part includes an ejection port. The first supply path is used for supplying ink from the first storage part to the second storage part and has a discharge port which is provided in the second storage part at a level higher than a predetermined specific position and lower than the ejection port. The regulation part regulates a backflow of ink in the first supply path. The second supply path is used for supplying ink from the second storage part to the ejection part and has a supply port which is provided in the second storage part at a level lower than the discharge port.

Inkjet recording apparatus capable of preventing backflow of ink

A document sheet conveyance device includes an inner guide and an outer guide defining a curved sheet conveyance passage for allowing conveyance of a document sheet from a document sheet feeding section to a predetermined document reading position, and a movable guide projectable into the sheet conveyance passage. The outer guide includes an outer curved guide surface defining an outer surface of the sheet conveyance passage. The inner guide includes an inner curved guide surface defining an inner surface of the sheet conveyance passage, and a first flat part. The movable guide includes a projecting portion projectable into the sheet conveyance passage, and a second flat part provided in the projecting portion. The movable guide is attached to the outer guide in such a way as to allow the first and second flat parts to face each other with the projecting portion projecting in the sheet conveyance passage.

Document sheet conveyance device and image forming apparatus including the same

An adjustment mechanism () adjusts a position of a target object () attached to an attachment base (). The adjustment mechanism () includes a first cam () and a second cam (). The first cam () is attached to a shaft portion () on the attachment base (). The second cam () houses the first cam () and supports the target object (). The first cam () displaces the target object () via the second cam () by rotating about the shaft section () as a rotational axis. The second cam () displaces the target object () by rotating about the first cam () as a rotational axis. An amount of displacement of the target object () resulting from rotation of the first cam () differs from an amount of displacement of the target object () resulting from rotation of the second cam ().

Adjustment mechanism, image forming apparatus including adjustment mechanism, and adjustment method using adjustment mechanism

A flow path opening/closing device includes a tube through which a recording liquid flows, a tube support member on which the tube is mounted, an opening/closing member configured to rotate between a closing position and an opening position, and an elastic support member. In the closing position, the opening/closing member crushes the tube mounted on the tube support member, thereby cutting off a flow path defined within the tube. In the opening position, the opening/closing member allows the cutoff of the flow path to be cancelled by a restoring force of the tube. The elastic support member elastically supports the tube support member so as to move the tube support member toward and away from the opening/closing member.

Flow path opening/closing device and inkjet recording apparatus provided with the flow path opening/closing device

An inkjet recording device is provided, which includes a recording head, a cleaning unit and a wiper cap member. The recording head includes a nozzle face on which an ink-injecting nozzle is formed. The cleaning unit includes a wiper case and a wiper member. The wiper case has a wiper accommodating portion and a wiper opening. The wiper member is configured to be accommodated in the wiper accommodating portion, protrude out of the wiper accommodating portion via the wiper opening and move relatively to the recording head to clean the recording head. The wiper cap member shuts the wiper opening of the wiper case.

Inkjet recording device

The present invention teaches and claims an image forming apparatus comprising: an image forming portion including one or more inkjet heads for forming an image on a recording medium by discharging ink from an ink discharge surface of the inkjet head; a recording medium transporting portion having a transport surface which is positioned below the ink discharge surface and on which the recording medium is placed for transporting a sheet to a position facing the ink discharge surface; a moving mechanism for moving the transport surface toward and away from the ink discharge surface; an ink discharge surface protecting mechanism including but not limited to a cap member and a driving device for moving the cap member; and a control unit for moving the transport surface away from the ink discharge surface to operate the ink discharge surface protecting mechanism when the recording medium is jammed during transportation of the recording medium.

In a cap mode where a cap member covers a nozzle surface, a controller controls a second movement mechanism so that the cap member is disposed opposite to the nozzle surface. In an ejection recovery mode where ink is ejected from a plurality of nozzles and the ink adhered to the nozzle surface is wiped off by a wiping member, the controller controls a first movement mechanism and the second movement mechanism so that the nozzle surface, a wiping tray and the cap member are arranged downward in this order.

Inkjet recording apparatus

An ink jet recording apparatus may include a recording head that extends in a direction perpendicular to a recording-medium-conveying direction. In some embodiments, the recording head may eject ink to a recording medium. An embodiment may include a recovery device that performs recovery processing of the recording head, the recovery device having a cap portion that covers an ink ejection surface of the recording head, and a wiping portion that wipes the ink ejection surface. In some embodiments, the recovery device may move along the recording-medium-conveying direction. When the recovery device moves along the recording-medium-conveying direction, the wiping portion wipes the ink ejection surface while moving along the recording-medium-conveying direction.
