An inkjet recording device is described in which maintenance is performed by a maintenance unit upon a recording head. The maintenance unit is located on a base unit. The base unit includes a wall portion supporting a plurality of gear shafts protruding in a width direction from the wall portion.

Inkjet recording apparatus

A conveyor device is described in which a conveyor roller is used to convey a medium inside a printing device with the conveyor roller extending in a width direction of the printing device. The conveyor roller receives a force from a following roller configured to face the conveyor roller. The conveyor roller is supported by one or more bearings. The one or more bearings include a shaft supporting portion that extends in the width direction to support the conveyor roller against the force of the following roller.

Conveyor device

A transporting apparatus includes a base unit made of resin, a tray configured to support a sheet, a transporting section supported by an upper portion of the base unit and configured to transport the sheet, and a feeding section supported by a lower portion of the base unit and including a feeding roller configured to contact an upper surface of the sheet supported by the tray and to feed the sheet toward the transporting section. The base unit is integrally formed with an inner-side guide which defines an inner side of a curved path which is configured to guide the sheet fed by the feeding section to the transport section.

Transporting apparatus

A conveying device includes: a conveyor for conveying a sheet; a path defining member having a first conveying surface that guides the sheet; and a sensor device for sensing the sheet. The sensor device includes: a sensor casing provided on the path defining member and including a second conveying surface that guides the sheet and a main wall whose outer surface is exposed from the path defining member and contiguous to the first conveying surface; a movable member including (i) a contact portion projecting to a second-conveying-surface side of the main wall through an opening formed in the main wall and (ii) a sensed portion located in the sensor casing and moved by the sheet conveyed on the second conveying surface while contacting the contact portion; and a signal output device, provided in the sensor casing, for sensing the sensed portion to output a signal related to its position.

Conveying device and image recording apparatus

A conveyor device may include first and second conveyor units, and a movable member. The first conveyor unit includes a first roller that contacts an upper surface of a sheet and a second roller that contacts a lower surface of the sheet. The second conveyor unit includes a third roller that contacts the lower surface of the sheet and a fourth roller that contacts the upper surface of the sheet. The first and second rollers and the third and fourth rollers nip and convey the sheet along a conveyance path. When the movable member is located in a first position, the first roller contacts the second roller and the third roller contacts the fourth roller. When the movable member moves to the second position, the first roller is moved away from the second roller and the third roller is moved away from the fourth roller.

An inkjet recording apparatus includes a support member having a plurality of ribs and supporting the sheet; a head disposed above the support member and ejecting ink to the sheet supported by the support member; and at least one contact portion disposed upstream of the head and configured to come in contact with the sheet so as to make the sheet a waved shape. The support member includes a first support portion comprising at least one first guide portions disposed corresponding to the at least one contact portion, and a plurality of second guide portions disposed corresponding to the plurality of ribs and disposed above the plurality of first guide portions. The support member further comprises a second support portion comprising a third guide portion disposed downstream of the first support portion.

A transport apparatus includes a transport roller having a first supported portion and a second supported portion at positions separated in a first direction, and configured to abut against a sheet, rotate in a second direction about a rotation axis extending in the first direction, and transport the sheet; a first support member configured to rotatably support the transport roller, the first support member having a first receiving portion which is in the form of a circular arc and configured to abut against a portion in a circumferential direction of an outer periphery of the first supported portion; and a second support member configured to rotatably support the transport roller, the second support member having a second receiving portion which is in the form of a circular arc and configured to abut against a portion in a circumferential direction of an outer periphery of the second supported portion.

Transport apparatus and image recording apparatus

In an inkjet recording apparatus, a support frame has a support part, and supports a carriage on a first surface of the support part. A pinch roller is disposed on a second surface side of the support part, the second surface being opposite from the first surface. A conveying roller is disposed opposite to the support frame relative to the pinch roller and in confrontation with the pinch roller. A roller holder is disposed on the second surface side of the support part and supporting the pinch roller. An urging member is interposed between the roller holder and the support part, and urges the roller holder to press the pinch roller against the conveying roller. The carriage is in contact with the first surface of the support part while the urging member is in contact with the second surface of the support part.

Inkjet recording apparatus having frame for supporting carriage

An ink-jet recording apparatus includes: a base member; a conveyor unit, supported by the base member, for conveying a sheet in a conveying direction parallel to a first direction; and a recording unit, supported by the base member, for ejecting ink when the recording unit is opposed to the sheet in a second direction perpendicular to the first direction. The base member is divided into a first base portion that supports the conveyor unit and the recording unit, a second base portion contiguous to the first base portion and located downstream of the first base portion in the conveying direction, and a third base portion contiguous to the second base portion and located downstream of the second base portion in the conveying direction. A stiffness of the second base portion is less than that of each of the first base portion and the third base portion.

Ink-jet recording apparatus

An ink-jet recording apparatus includes: a base member; a conveyor unit for conveying a sheet in a first direction; and a recording unit for ejecting ink when opposed to a sheet in a second direction. The base member includes: a first side base portion; a second side base portion; a center base portion located between the first side base portion and the second side base portion in a third direction; first and second side walls extending in the first direction and projecting in the second direction from opposite edge portions of the center base portion in the third direction; and a main board connecting the first side wall and the second side wall and configured to support the conveyor unit and the recording unit. The main board is greater in stiffness than the first side wall and the second side wall.
