Embodiment 1

[0055] FIG. 1( a ) is a diagram showing an example of a mobile phone 2 incorporating the keyway 1 of the present invention, and shows the state of the keyway 1 when it is not illuminated (visual mode). In addition to the liquid crystal display screen 3 and the casing part of the mobile phone 2, that is, the entire surface of the key groove 1 is visible in metallic colors such as shiny silver, and the characters, symbols, etc. displayed on the surface of each key cannot be seen.

[0056] Fig. 1(b) is the same as Fig. 1, showing the state of the keyway 1 when it is illuminated, and what is shown is that numbers 0 to 9 and alphabetic characters a to z and symbols *, + are displayed on each key top 4 by hollow characters , #, etc. (light is emitted from the surface of each key top 4 to present the shape of characters and the like, and the characters and the like are recognizable). The larger key is "4-way key 5 with OK key". This key 5 is a portion having a determination key at t...

Embodiment 2

[0078] In the embodiment shown in FIG. 1 of the present invention, various modifications are considered. The illustration in FIG. 5 is a second embodiment in which all the layers are provided on the upper surface of the key top 4 . First, a white undercoat layer 41 (solid color layer) is formed on the upper surface of the key top 4, and a hollowed-out character (intaglio) printing layer 40 is formed thereon by, for example, screen printing.

[0079] Then if a colorless or colored light-transmitting printing layer 40a is formed thereon, the hollowed out portion 40a will be filled with the material. A metal thin film (half mirror) 42 is formed thereon, and an intermediate coat 43 and an overcoat 44 are sequentially formed to protect the surface. Then, the lower part of the key top 4 is directly adhered on the key board 23 by the adhesive layer 27 of Xiuming.

Embodiment 3

[0081] The embodiment illustrated in FIG. 6 is a third embodiment in which all layers are provided under the key top 4 . First, the front and back of the key top 4 are reversed, a primer layer 41 is applied to the lower surface, and a hollow character printing layer 40 is formed through a metal thin layer (half mirror) 42 . Next, a colorless or colored light-transmitting printed layer 40a is attached in the shape of filling the hollow characters. Then stick on the key board 23 through the transparent adhesive layer 27 .

[0082] Therefore, in the case of this example, no layer is formed on the top of the key top 4 . That is, there is no need to form an overcoat responsible for protecting the surface of the key top 4 .

Abstract

The object of the present invention is a key sheet and a key top of novel design such that a character or a symbol cannot be recognized visually when not illuminated and can be recognized visually only when illuminated. In the key sheet (1) comprising a key top (4) for pressing a key and a key pad (23) on which a plurality of key tops are placed in a matrix and which supports them integrally through transparent adhesive (27), the key top (4) is composed of a transparent material, e.g. resin or glass, and provided with a metal thin film (half-silvered mirror) (42) on the upper or lower surfaces. Consequently, a character or a symbol cannot be recognized visually when not illuminated and can be recognized visually only when illuminated.

Description

technical field [0001] The present invention relates to a newly designed keyway and slot cap, which is used for the equipment with the keytop of the buckle input method, such as mobile phone, mobile data terminal (PDA), personal computer, etc., which has a metallic texture when it is not illuminated. The characters and symbols cannot be seen from the appearance, but the characters and symbols can be seen only when the light from the lighting source passes through when the light is illuminated. Background technique [0002] The keyway is an assembly composed of a plurality of keytops (press buttons) and a sheet-shaped keypad (keypad). A plurality of key tops (press buttons) are attached to the key plate with a transparent adhesive, and they are called an assembly because they can be integrated as a single assembly when the device is manufactured. [0003] In general fields other than technical fields such as key grooves and key tops (press buttons), it is known to form a met...
