However, anyone with experience in operation knows that when the car audio is in night/night operation, due to insufficient light, the user often uses the faint light emitted by the display to barely watch the function indication on the button, or even open the top of the car. Wall lighting, for the driver of the traveling vehicle, is quite inconvenient to use. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a text or pattern that can represent the button work P, even in an environment with insufficient light, the person can clearly see each operation button or rotary button. The location and function of the device, the electronic device with light guiding effect. 1300391 Thus, the electronic device with light guiding effect of the present invention comprises: a body; a circuit board disposed in the body, and the circuit board is provided with a control (four) way for performing a function, and a plurality of touch switches electrically connected to the control circuit; a plurality of light-emitting elements are disposed on the circuit board and located adjacent to the touch switches, and the light-emitting elements are electrically connected to the control circuit; a panel is disposed on the body; and a plurality of operation keys are disposed on the panel and electrically connected to the control circuit, and each operation button can actuate a corresponding touch switch to open and close, and each An operation key is provided with a light transmission area. In the present invention, the light of each of the light-emitting elements is outputted through the light-transmitting area on each operation key, thereby providing illumination effects around the operation keys, and even in a low-light environment, each can be clearly seen. The location and function indication of the operation keys. [Embodiment] The foregoing and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the accompanying drawings. As shown in FIG. 1 and FIG. 2, the electronic device 2 with the light guiding effect of the present invention is a preferred embodiment. In this example, the electronic device 2 is said to be a car audio. Bedsides, etc. have electronic devices that operate buttons or knobs. The electronic device 2 includes a main body 21, a circuit disposed in the main body 21, a 1300391'- board 22, a plurality of light-emitting elements 23 disposed on the circuit board η, a panel 24 disposed on the -21, and a plurality of The operation keys 25 disposed on the panel 24 are mounted with a plurality of electronic components (not shown) in the main body 21, including an optical disk drive, an optical disk drive, a frequency modulation/amplitude modulation device, and the like. The circuit board 22 is provided with a H-bank scheduling function (such as (4) playing a song from a CD player, controlling the volume, or switching to a radio station, etc.) (4) a circuit 221, and a plurality of touches electrically connected to the control circuit 221 The switch 222, a display 223 that can be exposed on the surface of the panel 24 and electrically connected to the control circuit 22, and at least one rotary button 26 electrically connected to the control circuit 221. Each of the touch switches 222 and the rotating button % are respectively provided with at least one of the foregoing light-emitting elements 23. In this example, the light-emitting elements 23 are illustrated by light-emitting diodes. Each of the operation keys 25 corresponds to each of the touch switches 222, and each of the operation keys 25 can be pressed by the user to actuate the corresponding touch switch to open and close. Each of the operation keys 25 is provided with a light transmission area. 251. In addition, the electronic device 2 of the present invention further includes at least one cover 27 which is disposed on the panel 24 and can cover the rotary knob 26. The cover 27 can be rotated by the cover 27, and the top surface of the cover 27 is also A light transmitting region 271 is provided. The light-transmissive areas 251 and 271 can form a text pattern, that is, a position or a function indication of each of the operation keys and the rotary knob 26, such as the numbers 1 to 6 and FM1, FM2, etc. shown in this example. Circle or "<", ">", etc. It should be particularly noted that the number of the light-emitting elements 23 around each of the touch switch 222 and the rotary button 26 can be determined according to the size of the corresponding light-transmitting regions 251 and 271. 1300391 As shown in FIG. 3, in the use of the electronic device 2, the light of the light-emitting element 23 is transmitted through the light-transmitting region 251 on each of the operation keys 25 or the light-transmitting region 271 on each of the spins 26, so that the light is used. Even in a low-light environment, it is still clear that each operation key 25 or rotation button 26 is in a private state, and the brightness of the display 223 (see FIG. 2) can be easily used by the user. And any operation key 25 or rotation of the key is operated quickly, so that the use convenience is improved. The present invention may further include at least one light guide member 28 disposed above the panel and capable of being worn by the opposite rotary knobs 26, the light guide member 28 is in the form of a transparent ring, one end of which is connected with the light-emitting elements 23 around the corresponding rotating button 26, and covers the other end of the light-guiding member 28, thereby being emitted by the light-emitting element 23. The light can be output to the outside through the respective light-transmissive areas 251, 271 more concentrated under the guidance of a cow (5) as shown by the arrow 31 in FIG. ° As shown in Figure 4, the present invention may also include a light collecting plate 29 positioned between the panel 24 and the panel. An opening 291 is defined in each of the touch switch 222 and the rotating button 26, and a surrounding wall is respectively extended toward the panel 24 and the circuit board 22, and each of the openings 291 is opened. A light collecting area 293 is defined in the same manner as the surrounding surrounding wall 292. The light-emitting areas 293 around the touch switch 222 and the rotating button % are respectively located in the same-light collecting area 293. Thereby, each of the touch switches 222 and the surrounding light-emitting elements 23 are surrounded by the surrounding light-emitting elements 292 in the same light-collecting area 293, so that the light: 3, 1300,391 light can be further improved. It is concentratedly passed through the collecting wire 293 and outputted outward by the corresponding through-region 25i. When the light-emitting elements 23 recorded in the Cyclone 26 pass through the concentrating area 293, and can enter a 憎 憎 1 π 卫 月 & 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟 纟The corresponding light transmitting region 271 is output to the outside. In summary, the electronic device 2 with the light guiding illumination effect of the present invention is provided with at least one illuminating element # 23 on each of the touch switches, such as the surrounding and the rotating button. The key h and the cover 27 are provided with light-transmissive areas 251, 271, so that the light emitted by the light-emitting element 23 can be outputted outward through the light-transmissive areas 251, 271 to provide a position for displaying each of the operation keys 25 or 260. And the function label can make the text or pattern representing the button function bright, even in the low light environment, the person can clearly see the position and function indication of each operation button 25, and the profit operation is even in the low light environment. The lower user can still operate the any-operation key 25 or the rotary_26 easily and quickly, improving the convenience of use. In addition, a light guide member ′ can be added to the position of each of the rotary knobs 26 on the panel 24, and a light collecting plate 29 can be additionally disposed between the panel 24 and the rotating plate 22, thereby making the light output of the light-emitting element 23 more Concentration, light guide lighting effect is better' so the present invention can indeed achieve the above purpose.
