Description
そこで上記問題点を解決するため本発明は、可撓性を有する第一フイルムと、可撓性を有する第二フイルムとを重ね合わせて第一，第二金型間に収納・挟持し、第二金型側から第二フイルムを介して、又は第一金型側から第一フイルムを介して、第一，第二フイルム間の第一，第二金型によって形成されるキャビティー内に溶融成形樹脂を充填して固化し、その後金型を取り外すことで成形樹脂製のキートップ本体の上下面を第一，第二フイルムで覆う構造のキートップを製造するキートップの製造方法であって、前記第二金型の前記キャビティーに面する部分に、前記溶融成形樹脂によって第二フイルムに生じるしわを防止する凸部を設けたことを特徴とする。 Then, in order to solve the above-mentioned problems, according to the present invention, the first film having flexibility and the second film having flexibility are superposed and stored and held between the first and second molds, Melting in the cavity formed by the first and second molds between the first and second films from the second mold side through the second film or from the first mold side through the first film A method of manufacturing a key top having a structure in which a molding resin is filled and solidified, and then the mold is removed to manufacture a key top having a structure in which the upper and lower surfaces of the key resin main body made of molding resin are covered with first and second films. A portion facing the cavity of the second mold is provided with a convex portion for preventing wrinkles generated on the second film by the melt-molded resin.
また本発明は、可撓性を有するフイルムを第一，第二金型間に収納・挟持し、第二金型側から前記フイルムを介して、又は第一金型側から、フイルムの上部の第一，第二金型によって形成されるキャビティー内に溶融成形樹脂を充填して固化し、その後第一，第二金型を取り外すことで、フイルム上に成形樹脂製のキートップ本体を取り付けた構造のキートップを製造するキートップの製造方法であって、前記第二金型の前記キャビティー内に、前記溶融成形樹脂によってフイルムに生じるしわを防止する凸部を設けたことを特徴とする。 Further, according to the present invention, the flexible film is accommodated and held between the first and second molds, and the film from the second mold side through the film or from the first mold side , the upper part of the film A melt-formed resin is filled and solidified in the cavity formed by the first and second molds, and then the first and second molds are removed to attach the key resin main body made of the formed resin on the film. A method of manufacturing a key top having a different structure, comprising: in the cavity of the second mold, a convex portion for preventing wrinkles generated on the film by the melt-molded resin is provided. Do.
