An ink cartridge includes a first wall and a second wall opposite the first wall. The ink cartridge also includes an ink chamber, an ink supply portion extending from the first wall in a first direction, and a communication path coupled to the ink supply portion and to the ink chamber. The ink cartridge includes a third wall which is substantially perpendicular to each of the first wall and the second wall, and a fourth wall which is substantially perpendicular to the first wall, the second wall and the third wall. The third wall has a recess formed therein, and the recess extends from the first wall towards the second wall in a second direction opposite the first direction. A plane which is parallel to the first direction and the fourth wall intersects at least a portion of the recess and at least a portion of the communication path.

An image forming apparatus may include a mechanism for forming a corrugated shape in a sheet to be conveyed. The mechanism may include various components include one or more pressing portions, one or more ribs, one or more discharge rollers, a switching mechanism and the like. In one arrangement, ribs and pressing portions configured to create the corrugated shape may be disposed at various locations upstream or downstream of the platen, recording portion and/or nozzles thereof. In one example, pressing portions may be disposed both upstream and downstream of the nozzles of the recording portion to maintain a corrugated shape in the conveyed sheet. Various other configurations may be used.

An image forming device may include a contact member and a support member configured to support a recording portion. In one or more arrangements, the contact member may be disposed on the support member and include a contact portion configured to contact a sheet being conveyed. In some examples, the support member may include a carriage frame. Additionally or alternatively, the image forming device may include a platen having a plurality of ribs. In one or more examples, the ribs may be configured to form a corrugated shape in a sheet in conjunction with the contact member. Still further, one or more of the ribs and the contact member may be movable.

An image recording apparatus configured to record images on front and back surfaces of a sheet, including: a head which ejects ink onto the sheet for recording; a sheet-supply roller which contacts the sheet so as to transfer the sheet for supplying to the head; a sheet-supply path which is provided between the sheet-supply roller and the head, which has a U-shape, and through which the sheet is transferred such that one of surfaces thereof opposite to the other of the surfaces contacted by the sheet-supply roller faces the head; and a sheet-stopping control section configured to control the sheet-supply roller such that the sheet transferred by the sheet-supply roller is stopped for a first time in the sheet-supply path in a state in which the sheet is deformed so as to have a U-shape, after an image has been recorded on the front surface of the sheet and before an image is recorded on the back surface thereof.
摘要:
A first convey roller conveys a sheet in a sheet conveying direction such that a leading edge of the sheet passes through a nip of a second convey roller disposed downstream from the first convey roller. The second convey roller rotates in a reverse direction by a first rotation amount corresponding to a first linear distance to convey the sheet in a direction opposite to the sheet conveying direction, such that the leading edge of the sheet is released from the nip of the second convey roller. In response to the rotation of the second convey roller in the reverse direction, the first convey roller rotates by a second rotation amount corresponding to a second linear distance in the reverse direction to convey the sheet in the direction opposite to the sheet conveying direction, such that the leading edge of the sheet contacts the nip of the second convey roller when the first convey roller has rotated by the second rotation amount and the second convey roller has rotated by the first rotation amount.

The invention describes an image recording device having a sheet supplying device that supplies sheets. The sheet supplying device has a first tray and a second tray that hold sheets, and a first and second shaft positioned over the first and second trays. A first rotating member contacts a sheet in the first tray, and a second rotating member contacts a sheet in the second tray. A first arm extends from the first shaft to the first rotating member, and a second arm extends from the second shaft to the second rotating member. A transmission device is coupled to the first arm member and the second arm member, and transmits selectively a rotational drive force from the first shaft to either the first or second rotating members. A recording unit records an image on the sheet supplied by the sheet supplying device.
