Patent ID: 8616679

Claim:
An inkjet printer comprising: an inkjet head which ejects ink toward a surface of a recording medium; a platen provided opposed to the inkjet head to support the recording medium from an opposite side of the inkjet head; an absorber provided opposed to the inkjet head at the same side as the platen with respect to the recording medium supported by the platen; and a conveying unit which conveys a plurality of recording media of different sizes in a conveying direction; wherein the absorber includes a plurality of regions which lie in a same plane parallel to a surface of the recording medium supported by the platen, and are different in absorption rate from one another in a plan view observed from a normal direction of the recording medium supported by the platen; wherein the conveying unit conveys the plurality of recording media so that a reference edge of each of the different sizes of recording media parallel to the conveying direction passes through a common reference position; wherein the absorber has the highest absorption rate in a first region, of the plurality of regions, corresponding to a portion of the absorber above which the reference edge of the recording medium is conveyed; wherein the absorber has a higher absorption rate in a second region, of the plurality of regions, corresponding to a portion of the absorber above which an opposed edge of one size of recording media, parallel and opposite to the reference edge of the recording medium, is conveyed, than an absorption rate in a third region, of the plurality of regions, corresponding to a portion of the absorber above which a front edge and a rear edge of the recording medium are conveyed, each of the front and rear edges extending orthogonal to the conveying direction and spanning a distance between the reference edge and the opposed edge; wherein the second region of the absorber includes a plurality of second regions corresponding to portions of the absorber above which opposed edges of the different sizes of recording media, which are parallel and opposite to the reference edges of the respective sizes of recording media, are conveyed; and wherein the plurality of second regions are different in absorption rate from one another.
