Abstract

The present invention is directed to an inkjet recording apparatus 100 capable of performing recording continuously on both surfaces of a web 1, including a plurality of recording heads H1 to H8 disposed on a substrate, driers 5a and 5b for drying the web 1 recorded by the recording heads H1 to H8, and guide rollers A1 to A8, B1 to B8, and G1 to G8 for guiding the web 1, in which a traveling path of the web 1 is switchable so that the web 1 passes between any selected adjacent ones of the recording heads H1 to H8, the recording head upstream of the position where the web passes performs recording on one surface 1a of the web 1, and the recording head downstream of the position where the web 1 passes performs recording on the other surface 1b of the web 1, and an inkjet recording method using the same.

Claims

1. An inkjet recording apparatus capable of performing recording continuously on both surfaces of a web, comprising:

a plurality of recording heads disposed therein;

a drier for drying the web recorded by the recording head; and

guide rollers for guiding the web,

wherein the guide rollers include an upper guide roller for guiding a web downward between selected adjacent recording heads when the web is located above a recording head, a left guide roller for guiding the web leftward to a recording head upstream of a position where the web passes and a right guide roller for guiding the web rightward to a recording head downstream of a position where the web passes,

the guide rollers including a plurality of upper guide rollers, a plurality of left guide rollers, and a plurality of right guide rollers,

the web switches its traveling path by being guided by a selected one of the upper guide rollers, the left guide rollers and the right guide rollers, so that the web passes between the selected adjacent recording heads,

the recording head upstream of a position where the web passes performs recording on one surface of the web,

the recording head downstream of the position where the web 1 passes performs recording on an opposite surface of the web, and

a traveling path through which the web is passed is switched so that the number of recording heads that is caused to perform recording on the one surface of the web and the number of recording heads that is caused to perform recording on the opposite surface of the web can be varied.

2. The inkjet recording apparatus according to claim 1, wherein the drier includes a first drier for drying the one surface of the web, and a second drier for drying the opposite surface of the web.

3. The inkjet recording apparatus according to claim 2, further including a plurality of additional recording heads disposed therein to perform recording on the one surface of the web.

4. The inkjet recording apparatus according to claim 1, wherein lower surfaces of the plurality of recording heads are disposed in an arch shape.

5. The inkjet recording apparatus according to claim 1, wherein the drier is an ultraviolet drier.

6. An inkjet recording method using the inkjet recording apparatus according to claim 2, comprising:

drying the web by the first drier after the recording head upstream of the position where the web passes between the selected adjacent recording heads performs recording on the one surface of the web, and

drying the web by the second drier after the recording head downstream of the position where the web passes between the selected adjacent recording heads performs recording on the opposite surface of the web.

7. An inkjet recording method using the inkjet recording apparatus according to claim 3, comprising:

drying the web using a virtual drier after at least one of the additional recording heads performs recording on the one surface of the web,

drying the web by the first drier after the recording head upstream of a position where the web passes between the selected adjacent recording heads performs recording on the one surface of the web, and

drying the web by the second drier after the recording head downstream of the position where the web passes between the selected adjacent recording heads performs recording on the other surface of the web.

8. The inkjet recording apparatus according to claim 1, wherein the recording heads are positionally-fixed to a substrate to respectively line up, and

the recording heads are detachably attached to the substrate.

9. The inkjet recording apparatus according to claim 1, wherein the recording heads are positionally-fixed to a substrate to respectively line up, and

the substrate is provided with a hole to not prevent a traveling path in which the web passes between the adjacent recording heads.
