Accordingly, the identification symbol, letter or number 15a is printed on the pattern 15b of the specific shape, so that the pattern of the specific shape printed on the focal length d (f) of the convex lens 11l ( 15b) is enlarged by the convex lens 11l to provide a three-dimensional effect, and the identification symbol, letter or number 15a printed on the upper part can obtain a visual effect as if floating on the pattern 15b of the specific shape. have.

The specific shape pattern 15b may have various shapes, and the same shape may have a shape that is repeated in a specific direction.

4C shows a cross-sectional view of another embodiment of the three-dimensional member 10.

Unlike the three-dimensional member 10 shown in FIG. 4B, the three-dimensional member 10 illustrated in FIG. 4C is provided with a transparent resin layer 11p on a specific region of the upper surface of the lens sheet 11.

In addition, the embodiment shown in FIG. 4 (c) is different from the embodiment shown in FIG. 4 (b), and the convex lens 11l of the lens sheet 11 is printed on the bottom surface of the two-spec 13. All of the patterns 15b of a specific shape have the difference that they are simultaneously printed on the focal length d (f) of the convex lens 11l of the lens sheet 11. Both the convex lens 11l of the lens sheet 11 and the pattern 15b having a specific shape printed on the lower surface of the transparent sheet 13 have a focal length d of the convex lens 11l of the lens sheet 11. f) at the same time has the advantage of simplifying the manufacturing process.

The reason why the transparent resin layer 11p is provided in the specific region of the lens sheet 11 is to cancel the lens effect (magnification effect) caused by the convex lens 11l of the lens sheet 11.

That is, the identification symbol, letter or number 15a for which a three-dimensional effect is not required is not enlarged by the convex lens 11l of the lens sheet 11 so that the transparent resin layer 11p is observed in an actual shape. Equipped.

Accordingly, a method of additionally providing a transparent resin layer 11p on the upper surface of the lens sheet 13 positioned above the identification symbol, letter or number 15a may be applied to the convex lens 11l of the lens sheet 11. It can give an enlargement effect.

Therefore, by selectively adding the transparent resin layer 11p on the lens sheet 11, the lens effect can be removed at the required portion, and the identification symbol, letters or numbers 15a can be clearly observed.

The transmission film 220 may be provided with a plurality of light transmitting portion 221 to selectively transmit light. As shown in FIG. 5 (b), when the LED 251 is activated, invisible identifiers are emitted.

In order to selectively emit light corresponding to each user input, the transmissive film 220 may be provided.

The region except for the portion corresponding to the identification symbol (or the light transmitting portion 221) of the transmissive film 220 may be coated with a material that can not transmit light.

In addition to coating a region except for the identification symbol 221 of the transmission film 220 with a material that blocks light, the three-dimensional member (not provided with a separate transmission film to selectively emit an identification symbol). 210) A method of directly coating the lower surface may also be used.

That is, the portion corresponding to the identification symbol, the light transmitting portion 221 is not coated with a coating material, other areas are coated with a coating material, it is a method for selectively transmitting light. The latter method has the advantage of reducing the thickness of the user input.

A rubber sheet 240 may be further provided below the transparent film 220. That is, the rubber plate member 240 may further include a plurality of openings 241 through which the LED 251 is inserted and penetrated between the three-dimensional member 210 and the circuit board 250.

The rubber plate 240 is formed with a plurality of openings 241 in which the LED 251 is inserted and seated, and may be made of a material having a certain degree of elasticity.

In addition, the rubber sheet 240 may be made of an adhesive material. When an adhesive material is applied to both surfaces of the rubber plate member 240, the circuit board 250 and the member disposed on the rubber plate member 240 may be firmly adhered to each other.

The opening 241 is accommodated by the LED 251 mounted on the circuit board 250 is inserted. Therefore, only the top surface of the LED 251 may be exposed to the top.

The opening 241 formed in the rubber plate 240 is preferably formed in a size corresponding to the size of the LED 251. That is, it is preferable to determine the size so that only the top surface of the LED 251 can be exposed to the outside.

The opening 241 may have a shape corresponding to the shape of the LED 251 mounted on the circuit board 250.

The rubber plate 240 removes the clearance between the circuit board 250 on which the LED 251 is mounted and the three-dimensional member 210 or the transmissive film 220 to be disposed on the rubber plate 240. It serves to attach the three-dimensional member 210 or the transmissive film 220 and the circuit board 250 to be disposed on the rubber plate 240.

The LED 251 provided on the circuit board 250 has a predetermined height and protrudes from the circuit board 250.

Therefore, if the rubber sheet 240 is not present, since the play caused by the LED 251 may occur, it may be further provided with a rubber sheet 240 to remove it.

As described above, the circuit board 250 on which the plurality of LEDs 251 is mounted may be provided below the rubber plate 240.

The circuit board 250 includes a plurality of touch regions 253 each equipped with a touch sensor (not shown) for receiving a user's touch input and converting the user's touch input into a touch signal, and the upper surface of the touch region 253. A plurality of LEDs 251 is mounted.

The touch sensor may be, for example, a capacitive touch sensor. The capacitive touch sensor operates by sensing a change in capacitance generated when the body or a specific object comes in contact with the body. The final output is detected by detecting the difference between the small capacitance change and the set value generated when the human body contacts the surface to be touched.

If the touch sensor can detect a user's touch input and generate a touch signal, various sensors besides the capacitive touch sensor may be employed.

As described above, the touch area 253 is a partitioned area of the circuit board 250 corresponding to the touch input area 212 of the three-dimensional member 210. Each touch area 253 may generate a control signal according to each touch input corresponding thereto.

LED 251 may be mounted on the upper surface of the touch area 253 of the circuit board 250, and the LED 251 may receive a touch input from the touch area 253 to generate a touch signal. In this case, the LED 251 may be controlled to emit light.

The LED 251 may be controlled to emit only the LED 251 mounted on the touch area 253 to which the touch input is applied, and the LED mounted on the touch area 253 to which the touch input is applied ( LEDs other than 251 may be controlled to emit light together or sequentially. That is, the pattern or method of emitting the LED 251 may be variously modified.

In addition, when LEDs other than the LED 251 mounted on the touch region 253 to which the touch input is applied are also turned on, the LED 251 mounted on the touch region 253 to which the touch input is applied first comes first. It is preferable to light up. This is for the user to easily determine that the touch signal is generated in the specific touch area.

In order to emit light, the diffusion member 230 is required.

Since the illumination of one identifier 221 becomes uniform, it may serve to improve the quality of the illumination.

In addition, the diffusion member 230 illustrated in FIG. 5 includes the diffusion part 223 and a blocking part 225 that blocks the transmission of light. The blocking unit 225 may block the interference between the light provided by each LED, so as to selectively emit the identifier.

In this case, the rubber plate 240 removes the gap that may exist between the circuit board 250 and the diffusion member 230, and attaches the circuit board 250 and the diffusion member 230. .

As described above, the diffusion member 230 gently diffuses the light and at the same time, the diffusion and the blocking unit selectively block or transmit the light to generate the LED 251 spaced apart from each of the touch regions 253. It can play a role of preventing the intermittent light from interfering with each other.

The diffusion part 231 is an area through which light can be diffused or transmitted, and the blocking part 233 is a part of the diffusion part that blocks light diffusion.
