A recording apparatus with a recording unit for recording an image on a recording medium in consonance with an image signal, a feeder for feeding the recording medium to the recording unit, first auxiliary feeding unit, which contact the feeder when the recording medium is cut sheet paper, but which is separated from the feeder when the recording medium is continuous sheet paper in order to form a feeding route for the continuous sheet paper, second auxiliary feeding unit, which contacts the feeder when the recording medium is cut sheet paper, but which maintains a contact position with the feeder which decreasing pressure against the feeder when the recording medium is continuous sheet paper, and third auxiliary feeding unit, which contacts the feeder when the recording medium is cut sheet paper, but which decreases pressure against the feeder when the recording medium is continuous sheet paper, and switching device for selecting the forward or the backward movement of the first and the second auxiliary feeding unit to the feeder, whereby the sliding center of the first auxiliary feeding unit with respect to the feeder.

Recording apparatus

The present invention provides an image recording apparatus with an image recording unit for recording an image on a recording medium, a first conveyor for conveying the recording medium to an image recording portion of the image recording unit while bending the recording medium along a drive convey roller by means of the drive convey roller, and a second conveyor for conveying an elongated recording medium having a plurality of pin holes to the first conveyor. A guide capable of changing a contact area between the recording medium and the drive convey roller at a curved portion of the recording medium along the drive convey roller is also provided.

Image recording apparatus having conveying means for both continuous

This invention may be used as a system in which a scanner for reading an original document and a recording apparatus are combined, and aims to provide an image information processing apparatus which facilitates the transportation of the system, and an image information processing system. A printer and a scanner can be mounted to each other by accurate positioning when positioning projections provided in the printer are engaged with positioning holes corresponding to the projections on the scanner side, and this mounting is fixed by the engagement of a hook on the scanner side with a recess on the printer side. In this mounted state, a transport passage, including a paper ejection port, for an original document or printing paper is formed, and motive power and electric power are supplied from the printer side to the scanner side via gears. In this state, an image on the original document is read, or an image is recorded on the printing paper.

Image processing apparatus and system having a detachable scanner unit

An ink jet recording apparatus for recording on a recording medium using an ink jet recording head that records by discharging ink from ink discharge ports thereof. The ink jet recording apparatus includes a carriage that carries the ink jet recording head and reciprocally moves the head in a manner such that the recording head is opposite the recording medium, and the carriage includes a temperature stabilization portion contactable with the ink jet recording head carried on the carriage, wherein the temperature stabilization portion radiates heat generated by the ink jet recording head.

Recording apparatus including recording head and temperature

A suction recovery device of ink jet recording apparatus comprises a cap which can contact with or separate from a face formed with discharge ports for recording by discharging the ink, the cap communicating to a suction system for performing the suction recovery through the discharge ports via the cap, said cap having a groove portion for guiding ink, and formed of an elastic material integrally with an ink communication member for communicating to the suction system via a suction port provided on an inner wall of the cap, and said suction system having a cylinder and a piston reciprocating within the cylinder, and having disposed ink absorbing member in an ink exhaust portion within the cylinder.

An ink jet recording apparatus has means for heating a recording medium guide member disposed near the ink recording area by a recording head for discharging ink, and means for changing the rate of heat imparted to the unit length of the recording medium with respect to the direction of conveyance thereof by the heating means in conformity with a parameter changing the environmental condition of the ink recording area.

Ink jet recording apparatus provided with fixating means

An ink jet recording apparatus for ejecting ink to effect recording on a recording material includes a carriage movable in a direction different from a direction in which the recording material is fed; and a pressing mechanism for pressing an end of an ink container for containing ink to be supplied to an ink jet recording head, wherein the pressing mechanism is effective to mount on the carriage the ink container and the ink jet recording head which are connected with each other by a connecting mechanism.

Ink jet recording apparatus and carriage mechanism therefor

A pump mechanism of an ink jet recording apparatus comprises a pump having a suction portion for sucking from a sucked member, said pump switching between the suction and non-suction operation of the suction portion by a reciprocating motion of a piston within a cylinder, without having a valve, a carrying member connected to said pump for carrying waste ink from said pump said carrying member opening to the atmosphere and a prevention mechanism for preventing a backflow of ink within said pump from the suction portion of said pump, to the outside of said pump which is caused by the reciprocating motion of the piston said prevention mechanism being an internal pump mechanism.

Ink jet recording apparatus and pump mechanism for use therewith

A recording apparatus effects a recording operation by scanning a recording medium in a predetermined direction with a recording head provided with discharge openings for recording liquid. A cap member is capable of covering a face with discharge openings of said recording head. A transmission member causes said cap member to cover said face with discharge openings in response to a motion setting said recording head to a predetermined position; and engaging members consisting of a protruding part are provided on one of said recording head and a carriage supporting said head. The protruding part engages a receiving part for said protruding part formed on the other of said recording head and said carriage, wherein said protruding part and said receiving part mutually engage at two points when said cap member covers said face with discharge openings.

Ink jet recording apparatus with recovery means

A method of cleaning a discharge port surface of an ink jet recording apparatus includes wiping the surface using a blade having a certain contact area with the surface and rubbing the surface using a rubbing member having a larger contact area with the surface than the blade. The wiping and rubbing operations are performed independently of each other so that their different purposes can be better accomplished. For example, since rubbing the surface need not be done as often as wiping, they can both be performed at optimum intervals. The rubbing member can be removably mounted to a replacement ink cartridge so that the rubbing member can be conveniently replaced at the same time as the cartridge.
