Abstract
A platen according to the invention has a metallic plate integrated thereto in such a manner that the plate surface is parallel to the direction of impact pressure applied from a printing section. Accordingly the platen has sufficient strength and rigidity even though being made of plastic, so that the platen is not deflected by impact pressure. A printer having the platen can maintain high print quality by preventing a decrease in print quality due to the deflection of the platen, thus reducing the cost of materials and achieving light weight.
Claims4
A platen comprising:
- a plastic platen cover having a platen surface in which a platen rubber is integrally embedded, the surface facing the printing surface of a print head, and a support portion integrally extending from the back of the platen surface backwardly;
- and
- a metallic platen plate integrally mounted to the support portion, with the plate surface being perpendicular to the platen surface of the platen cover.
A printer comprising:
- a print head;
- a plastic platen cover having a platen surface in which a platen rubber is integrally embedded, the surface facing the printing surface of a print head, and a support portion integrally extending from the back of the platen surface backwardly;
- a metallic platen plate integrally mounted to the support portion, with the plate surface being perpendicular to the platen surface of the platen cover;
- and
- a medium feeding unit feeding a print medium between the printing surface of the print head and the platen surface of the platen cover.
