Abstract: An ink printer cartridge is provided wherein ink is stored in a foam reservoir situated within an ink chamber. The foam reservoir does not substantially fill the interior space of the ink chamber, and in particular does not contact the lid of the cartridge. The foam reservoir is retained in place by means of a clip which abuts the top of the foam reservoir. In an embodiment, the clip may compress the foam. A number of features of clip are disclosed, including particular arrangements for fitting into the cartridge, and adjustments as to height and width.

Abstract: An ink-supplied wire dot matrix printer head for actuating wires with ink attached to tip ends thereof into contact with a sheet of print paper to transfer ink to the sheet, thereby forming ink dots thereon. The ink-supplied wire dot matrix printer head includes a wire guide member having a wire guide hole for guiding the tip end of the wire, and an ink tank containing an ink absorbing body therein and having an ink supply port in which a portion of the wire guide member is inserted. The wire guide member has a capillary ink path communicating with a side of the wire and supplied with ink from the ink absorbing body.

Abstract: A printer which is provided with a daisy wheel so that the types thereof are brought into contact with an ink roller to thereby apply ink onto the types and constructed to be disposed the ink roller at the position at an angle of 90.degree. or less circumferential of the daisy wheel from the printing position.The position of the types is grouped into two regions defined in connection with the ink roller set position and the rotation direction of the daisy wheel is decided by the region in which the types to be printed are positioned, in order to get high printing speed.The fingers located at a portion corresponding to the ink roller set position when the daisy wheel is in a printing-stand-by condition are smaller in length than others and have no type respectively, thereby preventing the daisy wheel from being deformation.

Abstract: An ink delivery system employing capillary member for delivering ink from a container directly to the tips of reciprocating print wires for ink transfer to a print receiving medium. Adjustment is provided for regulating the surface contact area between an ink container capillary member and a print head capillary member to regulate ink flow in order to accommodate printing speed and compensate for any factors which may alter ink flow, whether they be to cause more or less rapid ink flow. In a preferred embodiment, the ink container capillary member is moved relative to the print head capillary member. The capillary members are comprised of a porous material. Adjustment of ink flow is simplified through the provision of an easily movable handle arm and cooperating serrated slot for simply and rapidly adjusting the interface between the cooperating capillary members through which interface the ink is caused to flow.
