发明名称 Keytop sheet using film and its manufacturing method
摘要 In the present invention, a molding process of keptops is performed by inserting a previously silk-printed thin film into a mold. Therefore, it is possible to implement a small sized and light product by connecting a plurality of keytops using a film, and a tactile feel of a user is increased. In addition, in the present invention, since a silk printing process is not required, the productivity of a keytop sheet is enhanced, and it is possible to decrease the defect rate of the product compared to the conventional art.
