In a serial recording apparatus having three recording modes, i.e., normal, high-quality, and high-speed recording mode, sheet feed control satisfying requirements in these modes is performed. More specifically, high-speed sheet feed control is performed in the normal or high-speed recording mode, and low-noise sheet feed control with improved precision is performed in the high-quality recording mode although the speed is low.

Recording apparatus

The invention provides a carriage for a recording apparatus, comprising a head mounting portion on which a head cartridge is detachably mounted, a connector portion to be electrically connected with the head cartridge, an operating portion for rendering the head cartridge attachable to or detachable from the head mounting portion, wherein when rotated in a first direction, the operating portion fixes the head cartridge mounted on the head mounting portion and electrically connects the connector portion, while when rotated in a second direction opposite to that in the fixing operation, the operating portion releases the electrical connection between the head cartridge and the connector portion, and a connector protecting member adapted to protect the connector portion and being linked with the rotation of the operating portion. When the operating portion is rotated in a direction rendering the head cartridge detachable or mountable, the connector portion moves to a position protecting the connector portion, while when the operating portion is rotated in a direction fixing the head cartridge, the connector portion moves to a position exposing the connector portion.

Carriage and recording apparatus

An ink container for containing ink to be supplied to an ink jet head to which the ink container is detachably mountable, inclues an ink supply port for supplying the ink to the ink jet head; a air vent for fluid communication with ambience; a claw-like projection provided on a first side of the ink container; a latching lever provided on a second side opposite from the ink container, the latching lever being resiliently supported on the ink container and having a latching claw.

A recording apparatus comprises a first gear, a second gear meshable with the first gear, a third gear meshable with the first gear and the second gear. The third gear has a peripheral surface on which a toothed portion meshable with the first gear and an untoothed portion not meshable with a toothed portion of the first gear are disposed opposable to the first gear, and a peripheral surface on which a toothed portion meshable with the second gear is disposed opposable to said second gear, a gear drive switching control unit controls switching such that when the toothed portion adjacent the untoothed portion of the third gear comes into contact with the first gear, the second gear and the third gear are meshed to rotate the third gear to oppose the untoothed portion of the third gear to the first gear, thereby releasing the contact between the first gear and the third gear.

A recovery device is described for use with a recording head of an ink jet recording apparatus. The recording head is mounted on a carriage which can reciprocate. The recovery device includes a cap for capping an ink discharge portion of the recording head when not in use, and a wiper for wiping out the ink discharge portion with a movement of the carriage. The wiper is disposed outside the cap relative to the recording area. The recording head does not pass through an area occupied by the wiper when the recording head performs a predischarge with respect to the cap during recording.

A recording apparatus for performing recording on a recording medium by use of a recording head, the recording apparatus comprises a carriage for reciprocal scanning of the recording head for recording on the recording medium, a guide for guiding the carriage in directions of the reciprocal scanning, and a positioning member and a press member located opposite to each other with the guide in between on the carriage, wherein the press member is not pressed against the guide in a region except for a predetermined region in a reciprocal scan region of the carriage and the press member is pressed against the guide in the predetermined region.

In the sheet conveying apparatus, convey force of a convey device is changed according to the load applied to a recording sheet in order to constantly convey the recording sheet reliably. A rotary sheet discharge body has convex and concave portions in order to reliably discharge the recording sheet regardless of resistance applied to the recording sheet. Highly frictional material is provided only around the end portions of the rotary sheet discharge body in order to reduce the manufacturing cost and improve the facility of assembly.

Recording apparatus having a sheet conveying force adjustment system

A sheet supplying apparatus includes a sheet supporter for supporting sheets, a supply rotary device for feeding out the sheets supported by the sheet supporter, a separation member for separating sheets fed by the supply rotary device one by one by elastically changing an inclination angle of the separation member when the sheets fed by the supply rotary means abut against and ride over the separation member, and a sheet guide member removably disposed above the sheet supporting means and adapted to guide the sheet in such a manner that the sheet is subjected to resistance of the separation member smaller than resistance from the separation member to the sheet when the sheets are supplied from the sheet supporter.

Sheet supplying apparatus

A container for safekeeping an ink jet cartridge is provided with the main body of a container for storing an ink jet cartridge having a recording head unit, and an ink tank unit containing ink to be supplied to the recording head unit, a lid element for covering the inlet and outlet of the main body of the container for storing or removing the ink jet cartridge, an elastic cap member provided in the main body of the container for covering the recording head unit. This container for safekeeping an ink jet cartridge comprises a rib arranged on the inner wall surface of the lid element for exerting pressure on the recording head unit of the ink jet cartridge to press it to the elastic cap member; and a recess arranged on the inner wall surface of the main body of the container in a position corresponding to the location where the elastic cap member is arranged. In this way, it is possible to cap the recording head appropriately in the container to provide a highly reliable safekeeping of the ink jet cartridge, and at the same time, to store and safekeep the ink jet cartridges for monochromatic use and color uses exhangeably.
