  • Patent number: 6789966
    Abstract: In a printer, in which printing is performed on a recording medium which is transported in a first direction, a carriage is reciprocately moved in a second direction which is perpendicular to the first direction. A print head is mounted on the carriage, and provided with a head face. A frame is placed in a first side of the print head. A guide plate extends in the second direction. The guide plate includes a first portion provided as a part of the frame so as to extend in a third direction which is orthogonal to both of the first direction and the second direction, a second portion continued from the first portion so as to extend in the first direction. The second portion supports the carriage so as to define a distance between the head face and the recording medium. The guide plate further includes a third portion continued from the second portion so as to extend in a fourth direction opposite to the third direction.

  • Publication number: 20040021737
    Abstract: There is disclosed an ink cartridge capable of being removably held in an ink cartridge accommodation portion simply by pushing in the cartridge in an insertion direction. The ink cartridge (5) is mounted on a carriage (4) having a cartridge accommodation region. A one-push type fixing member (30) in a position facing a surface parallel to an insertion direction in which the cartridge is inserted into the cartridge accommodation region is engaged with a fixing protrusion (12a) forming another one-push type fixing member and cooperating with the first-mentioned one-push type fixing member, so that the cartridge (5) is held in a predetermined position in a state in which the cartridge is resiliently urged by a spring (24) in a direction opposite to the insertion direction.

  • Patent number: 6547237
    Abstract: A sheet feeding roller is brought into contact with an uppermost sheet stacked on a hopper, and rotates to feed the uppermost sheet to the recording apparatus. A separation pad presses the uppermost sheet against the feeding roller so that the upper most sheet is separated from a next uppermost sheet. A first sheet returner pushes back a first part of the next uppermost sheet situated on the separation pad to the hopper. A second sheet returner pushes back a second part of the next uppermost sheet situated on the separation pad to the hopper. The sheet feeding roller, the separation pad and the first sheet returner are incorporated in a single unit which is disposed at a first position of a sheet feeding passage formed on the hopper. The second sheet returner is solely disposed at a second position of the sheet feeding passage.
