Abstract
A printer comprises a transportation belt, a printer head, and a pneumatic paper sucker. The transportation belt is driven by a driving roller that drives a driven roller. The printer head includes a plurality of head units each having ink-jet surfaces. In the printer, print paper is adsorbed to the transportation belt by the sucker, and transported in a direction of transportation. Ink drops jetted out from the head units are shot at correct points on the print paper specified in print data. Thus, printing is achieved. According to the printer, the printer head need not be shifted in the process of printing, but printing can be achieved at a high speed. Moreover, the costs of manufacturing can be reduced, and the printer can be designed compactly.
Claims10
A printer comprising:
- a printer head capable of printing one full line on print paper without having to be shifted in a width direction of the print paper;
- a transportation belt comprising an endless belt member which holds the print paper and transports the print paper in a direction orthogonal to the width direction of the print paper;
- a printing control means for controlling jetting of ink drops from said printer head synchronously with transportation of the print paper by said transportation belt so as to achieve printing;
- a print paper positioning means for positioning the print paper at a predetermined place on said transportation belt;
- wherein said print paper positioning means comprises marks inscribed on said transportation belt in order to detect a position of the print paper held on said transportation belt, a mark detecting means for detecting the marks, and a print paper supplying means for supplying the print paper according to an output of said mark detecting means;
- and
- wherein said print paper supplying means supplies the print paper at a timing of the output of said mark detecting means, and the print paper is held in the predetermined place defined by the position of the paper held on said transportation belt which is detected using said marks.
A printer comprising:
- a printer head capable of printing one full line on print paper without having to be shifted in a width direction of the print paper;
- a transportation belt comprising an endless belt member which holds the print paper and transports the print paper in a direction orthogonal to the width direction of the print paper;
- a printing control means for controlling jetting of ink drops from said printer head synchronously with transportation of the print paper by said transportation belt so as to achieve printing;
- wherein said printer head is adapted to print in multiple colors, and comprises a plurality of single-color head blocks each having a plurality of head units arranged along a single oblique line.
A printer comprising:
- a printer head capable of printing one full line on print paper without having to be shifted in a width direction of the print paper, said printer head comprising a plurality of nozzles;
- a transportation belt comprising an endless belt member which holds the print paper and transports the print paper in a direction substantially orthogonal to the width direction of the print paper;
- and
- a printing control means for controlling a timing of jetting out ink from said nozzles according to a variation of an ink-jet distance between the print paper held on said transportation belt and an ink-jet surface included in said printer head so that ink drops are shot at correct points on the print paper.
A printer comprising:
- a printer head capable of printing one full line on print paper without having to be shifted in a width direction of the print paper, said printer head comprising a plurality of nozzles;
- a transportation belt comprising an endless belt member which holds the print paper and transports the print paper in a direction orthogonal to the width direction of the print paper;
- and
- a control unit which controls jetting of ink drops from said printer head synchronously with transportation of the print paper by said transportation belt so as to achieve printing,
- wherein said transportation belt comprises a recovery area in which said printer head is enabled to recover an ability to jet out ink, said recovery area comprises at least one aperture which is smaller in size than said printer head so as not to disturb jetting of ink from said printer head, and said at least one aperture does not contact said printer head as said printer head recovers the ability to jet out ink.
