Ink-jet recording apparatus

Abstract

An ink-jet recording apparatus includes: a recording medium transporting portion that transports a web-like recording medium; an ink-jet heads that include a nozzle portion and ejects an ink on the basis of an image signal toward the web-like recording medium transported by the recording medium transporting portion, the ink being curable by active energy rays; an active energy irradiating portion that comprises a light source irradiating the active energy rays and cures the ink ejected onto the web-like recording medium by the active energy rays irradiated from the light source; and a transporting direction changing portion that is disposed right by at least one of an upstream and downstream sides of the active energy irradiating portion in the transporting direction of the recording medium at a position between ink-jet heads, and that changes a transporting direction of the recording medium to a direction vertical to the transporting direction.

Claims

1. An ink-jet recording apparatus comprising: a recording medium transporting portion that transports a web-like recording medium;ink-jet heads that comprise a nozzle portion and ejects an ink on the basis of an image signal toward the web-like recording medium transported by the recording medium transporting portion, the ink being curable by active energy rays;an active energy irradiating portion that comprises a light source irradiating the active energy rays and cures the ink ejected onto the web-like recording medium by the active energy rays irradiated from the light source; anda transporting direction changing portion that is disposed right by at least one of an upstream and downstream sides of the active energy irradiating portion in the transporting direction of the recording medium at a position between ink-jet heads, and that changes a transporting direction of the recording medium to a direction vertical to the transporting direction.

2. The ink-jet recording apparatus as claimed in claim 1, wherein the light source of the active energy irradiating portion is positioned below a horizontal plane including the nozzle portion of the ink-jet head.

3. The ink-jet recording apparatus as claimed in claim 1, wherein the transporting direction changing portion comprises a roller.

4. The ink-jet recording apparatus as claimed in claim 3, wherein the roller is heated to from 40 to 150° C.

5. The ink-jet recording apparatus as claimed in claim 1, which comprises a light-shielding cover extending between upstream and downstream transportation rollers, the light-shielding cover being disposed behind the active energy irradiating portion.
