Abstract
An inkjet printer is provided. The inkjet printer includes: 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; and 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. The absorber includes a plurality of regions different in absorption rate from one another in a plan view observed from a normal direction of the recording medium supported by the platen.
Claims11
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.

An inkjet printer comprising:
- a platen which supports a recording medium;
- an inkjet head which ejects ink on the recording medium supported by the platen;
- and
- an absorber which is provided at lower position from the inkjet head with respect to a top of the platen and which absorbs the ink ejected from the inkjet head, the absorber including a plurality of regions which lie in a same plane parallel to a surface of the recording medium supported by the platen, and have different ink absorption capability in a plan view observed from an ink ejecting direction of the inkjet head;
- a conveying unit which conveys the recording medium in a conveying direction;
- wherein the absorber include a first region, of the plurality of regions, at one end thereof, the first region having a highest ink absorption capability in the absorber;
- wherein one edge of the recording medium parallel to the conveying direction passes above the first region of the absorber when conveyed by the conveying unit;
- wherein the absorber includes a plurality of second regions, of the plurality of regions, provided at specific intervals from the first region;
- wherein the second regions each have a higher ink absorption capability than that of another region, of the plurality of regions, of the absorber other than the first region;
- and
- wherein the second regions have ink absorption capability different from one another.
