Thin film application device and thin film forming method

Abstract

A thin film application device used to apply a thin film on an applied face of an application object includes a frame mountable to the application object, and a thin film holding member, that has a tentative application portion to which the thin film can be tentatively applied to a side face facing the applied face in use, and that is supported by the frame so that the tentative application portion can be pressed against the applied face, and that is detachably mountable to the frame.

What is claimed is: 
     
         1 . A thin film application device used to apply a thin film on an applied face of an application object, the thin film application device comprising:
 a frame mountable to the application object;   a thin film holding member, that has a tentative application portion to which the thin film can be tentatively applied to a side face facing the applied face in use, and that is supported by the frame so that the tentative application portion can be pressed against the applied face, and that is detachably mountable to the frame; and   
       a supporting portion supports the thin film holding member with the side face of the thin film holding member facing the applied face when the frame is mounted to the application object; 
       wherein the supporting portion is provided to be capable of displacement as to a frame main unit of the frame, and moves between a first position where the supporting portion covers the applied face when the frame is mounted on the application object, and a second position where the supporting portion does not cover the applied face when the frame is mounted on the application object. 
     
     
         2 . The thin film application device according to  claim 1 ,
 wherein the thin film holding member includes
 a supporting base detachably mountable to the frame, and 
 a soft member fixed to the supporting base in a layered state, 
   wherein the tentative application portion is provided on a side face of the soft member that faces the applied face in use.   
     
     
         3 . The thin film application device according to  claim 1 ,
 wherein the frame has a retaining portion that is capable of being retained to the application object.   
     
     
         4 . The thin film application device according to  claim 1 ,
 wherein the tentative application portion has the shape of a curved face.   
     
     
         5 . The thin film application device according to  claim 1 ,
 wherein the frame has a reference point indication portion that indicates a reference point for position coordinates obtaining of the applied face when mounted to the application object.   
     
     
         6 . A thin film forming method of forming a thin film that, in a state of being tentatively applied to a tentative application portion of a thin film application device, is pressed against an applied face of an application object, thereby applying the thin film to the applied face, the method comprising:
 obtaining of an object image that is an image where the application object is a subject, including at least the applied face;   obtaining of coordinates in the object image of coordinates of a position corresponding to the applied face, as to a reference point on the thin film application device, as object coordinates; and   printing a overlaying image on a thin film material of the thin film, that is overlaid on the applied face, at a portion corresponding to the object coordinates as to the reference point,   
       wherein, in the step of obtaining as object coordinates, the application object that has mounted the thin film application device in an opened state is in the object image,
 and wherein, in the step of obtaining as the object coordinates, the reference point is taken as a device base point formed on the front side of the thin film application device. 
 
     
     
         7 . The thin film forming method according to  claim 6 ,
 wherein, in the obtaining of the object image, the application object that has not mounted the thin film application device is in the object image,   and wherein, in the obtaining of the object coordinates, an object base point of the application object is obtained from the object image, and coordinates of a position corresponding to the applied face as to the object base point are converted into coordinates where the base point on the thin film application device is an origin, which are taken as object coordinates.
