摘要:
A transfer sheet 10 for use in printing of patterns 12, 16 such as alphanumeric characters onto a keyboard or other workpiece from the transfer sheet where the patterns 12, 16 are originally formed has a realignment area 17 in which a plurality of slits 13, 14 are formed. The slits 13, 14 allow at least one portion of the transfer sheet 10 to be repositioned with respect to at least one other portion to improve alignment of the patters 12, 16 with respect to the workpiece. The patterns 12, 16 may become misaligned because of inherent dimensional instability of the transfer sheet 10 arising from temperature or humidity variations.

摘要:
The invention relates to an operating element cap (1), comprising a cap body (2) for covering and/or actuating a switch of an associated operating element, wherein in the cap body (2) a luminous or projection area is configured in such a way that a symbol (5) represented on or by the luminous or projection area becomes visible to an operator of the operating element by means of irradiation by means of a light source arranged on the switch side. The operating element cap according to the invention is distinguished by the fact that the luminous or projection area comprises a film (4), wherein the film (4) comprises a transparent substrate, a plurality of small light-refracting balls connected in optical contact with the substrate, an opaque matrix surrounding the small balls, and optionally a diffuser or a diffuser layer, wherein the light originating from the light source passes through the small light-refracting balls, the substrate and, if appropriate, the diffuser or diffuser layer. The invention furthermore relates to an associated production method, an operating element comprising the above-described operating element cap, and a use.
摘要:
Provided is a decorative molded object (1,21,31,41,51,61) such as a key top for a push-button switch excellent in transparency of a color design image, and a method of producing such a decorative molded object (1,21,31,41,51,61). By a method of producing a decorative molded object (1,21,31,41,51,61) which is a resin molded object (2) decorated with a color design image representing a letter, a symbol, a figure, or the like, including the steps of: printing a color design image on an image carrying layer (8), which is porous and is arranged on a substrate sheet (9), with an output apparatus that collectively outputs color design data to form a coloring agent layer (10) for displaying the color design image on the substrate sheet (9); transferring the coloring agent layer (10) on the substrate sheet (9) onto a resin molded object (2) to be decorated; peeling the substrate sheet (9) with the transferred coloring agent layer (10) left on the resin molded object (2) to form a color design image layer (3) on the resin molded object (2); and curing, after application and deposition onto the color design image layer (3), a transparent resin liquid to thereby form a transparent resin layer (5), a decorative molded object (1,21,31,41,51,61) which is a resin molded object (2) is decorated with a color design image representing a letter, a symbol, a figure, or the like can be obtained.
摘要:
A method of manufacturing a key top for a push-button switch (7,14,19,23,24,25) according to the present invention includes forming a hot-melt adhesive layer (3,11,16) on a resin key top (4) so as to have a shape corresponding to a display portion (5) for displaying a letter, symbol, or other indicia, and transferring a metallic thin film layer (2,12,17) onto the hot-melt adhesive layer (3,11,16). Therefore, the metallic thin film layer (2,12,17) is not damaged due to coating of the hot-melt adhesive layer (3,11,16), and positioning of the display portion (5) is unnecessary. Further, when a transfer resin layer is formed on the metallic thin film layer (2,12,17), oxidation of the metallic thin film layer (2,12,17) or damages thereto can be prevented.
摘要:
A decorated key top presenting light transmitting iris gloss and good appearance giving a feeling of high quality, that can be produced at low cost through a continuous production process in which a liquid crystalline organic polymer layer (4) preferably of cholesteric orientated liquid crystalline organic polymer is formed on the key top (10) surface and/or back, and methods for manufacturing such a decorated key top.
