Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An ink jet recording apparatus comprises an ink tank containing ink; a recording head for performing recording by selectively ejecting ink; a mounting portion for mounting the ink tank and the recording head; a liquid passage coupling portion provided on either or both of the ink tank and the recording head for separating or connecting the ink passages in the ink tank and the recording head; a holding portion provided on either or both of the ink tank and recording head for guiding the ink tank to the recording head in order to hold them separably; and an electrically or mechanically connecting portion provided on either or both of the recording head and mounting portion for electrically or mechanically connecting the recording head to or separating it from the mounting portion.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A dot matrix printer has a vertical array of wires for printing on paper, pivotal armatures having plungers, coils wound around cores, main and auxiliary yokes the latter of which has drawn inner and outer peripheries, and posts at positions of the auxiliary yoke corresponding to the shortest paths of magnetic fluxes generated by the coils. Displacement of the auxiliary yoke upon pivotal movement of armatures is minimized to keep a constant gap between the cores and the plungers and to reduce noise. The reluctance of the magnetic circuit is small to improve magnetic efficiency.
