Abstract
The present invention relates to an inkjet image forming apparatus capable of recording non-margin images on a recording medium by discharging ink from a recording head to regions within as well as beyond edges of the recording medium. The apparatus includes an ink absorbing material for receiving ink discharged at a position beyond the recording medium and a platen having a holding portion to hold the ink absorbing material and supporting the recording medium at a recording position. The holding section formed at the platen has an opening for receiving the ink and is formed with a wall for holding a periphery of the ink absorbing material and a rib supporting a bottom of the ink absorbing material.
Claims16
An inkjet image forming apparatus capable of recording non-margin images on a recording medium by discharging ink from recording means to regions within as well as beyond edges of the recording medium, comprising:
- an ink absorbing material for receiving ink discharged at a position beyond the recording medium;
- a platen for supporting the recording medium, said platen having a holding portion to hold said ink absorbing material, wherein said holding portion is formed with a wall for holding a periphery of said ink absorbing material, and wherein said platen has a first opening through which the ink is received by said ink absorbing material, and a second opening open to a bottom surface of said ink absorbing material;
- and
- a rib being in contact with the bottom surface of said ink absorbing material, so that the ink disposed at a lower portion of said ink absorbing material moves downward along said rib and drips from said rib.
An inkjet image forming apparatus capable of recording non-margin images on a recording medium by discharging ink from recording means to regions within as well as beyond edges of the recording medium, comprising:
- a platen having a holding portion to hold the ink absorbing material,
- wherein an opening is formed in a wall at a position corresponding to the recording means at said platen and a slope is formed at least at a part of the opening and inclined with respect to a conveyance direction of the recording medium, and
- wherein the opening, except at a position of the slope, has a grid shaped rib extending downward from a lower edge of the slope.
An inkjet image forming apparatus capable of recording non-margin images on a recording medium by discharging ink from recording means to regions within as well as beyond edges of the recording medium, comprising:
- an ink absorbing material for receiving ink discharged at a position beyond the recording medium;
- a platen for supporting the recording medium, said platen having a holding portion for holding said ink absorbing material, wherein said platen has a first opening through which the ink is received by said ink absorbing material and a second opening open to a bottom surface of said ink absorbing material;
- and
- a rib being in contact with the bottom surface of said ink absorbing material, so that the ink disposed at a lower portion of said ink absorbing material moves downward along said rib and drips from said rib.
An inkjet image forming apparatus capable of recording non-margin images on a recording medium by discharging ink from recording means to regions within as well as beyond edges of the recording medium, comprising:
- a platen for supporting the recording medium,
- wherein said platen has a slope inclined with respect to a conveyance direction of the recording medium and an opening adjacent to a lower end of the slope, and wherein ink droplets discharged from the recording means arrive on the slope and flow to the opening.
