[Prior Art] With the development of technology, an input unit having a light-emitting effect has been common, and FIG. 6 discloses one of them, which is an illumination knob including a rotation encoder 1 and a plurality of located around the rotary encoder 11. The light source 12, a light guiding ring 13 on the light source 12, and a rotating wheel 14, the rotating wheel 14 and the rotary encoder 11 are fixedly connected and located on the light guiding ring 13, and the light emitted by the light source 12 is diverged through the light guiding ring 13 The runner 14 is evenly projected. However, the illuminating knob only has a rotary input mode, and does not press the input mode, and cannot adapt to the need for the input unit to have more input modes as the functions of the electronic device become more and more abundant. [New Content] In view of this, an integrated input unit is provided which has a lighting effect and has a rotation input and a press input. The input unit includes a housing, a printed circuit board in the housing, a multi-directional button, and a transparent wheel. The printed circuit board has an encoder circuit, a plurality of push contacts, and a plurality of light sources. The button is cylindrical and is located on the push-down contact, the top surface being exposed to the outside of the housing, the button being depressed to cause a pressed input to produce a push-in input. The light-transmitting wheel has a ring shape, and the wheel surrounds the button and is located on the encoder circuit. The top surface of the wheel is exposed outside the casing, and the wheel has at least one elastic piece and a reflective layer in contact with the encoder circuit, and the rotating wheel can be Rotating, so that the encoder circuit produces a rotary input, the light from the light source is reflected by the reflective layer 6 M353412 and then emitted from the light-transmitting wheel. Miscellaneous input and rotation of the input and rotation of the wheel can be carried out. The new type replaces the rotary encoder ring with an encoder circuit, so that the wheel unit has fewer components and is less difficult to assemble.扪 , , 减少 减少 • • • • • • • 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 入 So So So So So A button 60 and a housing 40. Referring to Figures 2 and 3, the PCB 2G has an encoder dry circuit 21 in a ring shape. On the pcb board 20, there are also a number of •A stone and a light source 23. In the present embodiment, the pressing contact 22 ("" is five 'in a cross-shaped arrangement 'the light source' is a light-emitting diode The four encoder circuits 21 surround the contact 22 and the light source 23. Referring to Figure 2, Figure 5, the light-transmitting wheel 50 is located on the pcb board 2, and the light wheel 5G has at least The elastic piece 55 is in contact with the encoder circuit 21 and a reflecting surface 56. The transparent rotating wheel 50 has an annular shape, and includes a bottom portion 51 and a top portion 52 extending upward from the bottom edge and having an inverted L shape. The bottom portion 51 is in the shape of a tooth, and includes a plurality of teeth 54 on the outer peripheral surface. The top surface of the top portion 52 is shaped like ===敎路53, money_封钱(4) handcuffs for the passage 7 M353412' the shrapnel 55 is located at the bottom 51 On the bottom surface, the reflecting surface 56 is located on the side of the top 52. The reflecting surface 56 can be formed by coating the opaque coating on the transparent rotating wheel 50. Please refer to FIG. 2 and FIG. 4 together, the button 60 is more than one. The button is corresponding to the pressing contact 22 on the PCB board 20. In the embodiment, the button 60 is a five-way button. The button 60 is generally cylindrical. A ring flange 61 protrudes outwardly from the bottom. The input unit 10 further includes an annular fixing frame 70 having an inner diameter larger than the outer diameter of the button 60 and smaller than the outer diameter of the flange 61. A plurality of connecting legs 71 extend downwardly from the ring-shaped fixing frame 70. In the embodiment, the connecting leg 71 is an L-shaped hook 71. The ring-shaped fixing frame 70 is sleeved on the button 60 and is in contact with the flange 61. The hook 71 hooks the PCB board 20 to fix the button 60 to the PCB board 20. In other embodiments, the holder 70 may have a plurality of pieces, which are inverted L-shaped, one end hooks the flange 61, and the other end passes The soldering method is fixedly connected to the PCB board 20. Since the structure of the button 60 is already prior art, it will not be described here. The housing 40 is for housing the PCB board 20, the light transmitting wheel 50 and the button 60. In the embodiment, the housing 40 is a ring having an inverted L-shaped cross section, and a post 41 is formed in the housing 40 for fixing an elastic member 30. When the input unit 10 is mounted, the ring type fixing bracket 70 is used first. Fixing the button 60 on the PCB board 20; then placing the light-transmitting runner 50 on the button 60; then, setting the elastic member 30 On the vertical column 41, the housing 40 is sleeved on the transparent rotating wheel 50, so that the elastic member 30 and the teeth 54 of the transparent rotating wheel 50 are engaged; finally, the housing 40 and the PCB board 20 are screwed (not shown). Fixed connection. Install the 8 'M353412 good input unit 10, the transparent wheel 50 and the top surface of the button 〇6〇 are exposed outside the housing 40 to accept the user's operation. 'When used' button 60 can be pressed Lower 'and thus the corresponding push contact 22' produces a push input. The runner 50 can be rotated and the shrapnel % slides on the horn circuit 21 to cause the encoder circuit 21 to produce a rotary input. Each time the runner 50 rotates a tooth 54, the elastic member 3 is elastically deformed and restored, and the elastic force generated thereby causes the runner 5 to have a good rotation. Referring to FIG. 5, the light emitted by the light source 23 is reflected by the reflecting surface, and then the entire light transmitting wheel 50 is evenly distributed, and then emitted from the top surface of the transparent rotating wheel 5〇, so that the input member 10 is insufficient in light. It can also be used in time or in the dark. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an input unit of a preferred embodiment of the present invention.
