The utility model content
The utility model provides a kind of integrated input unit, and it has illumination effect, and has the rotation input and press input.
Described input unit comprises a housing, is arranged in a printed circuit board (PCB), a multidirectional key and a transparent rotating wheel of housing.One encoder circuit, a plurality of by lower contact and a plurality of light source is arranged on the printed circuit board (PCB).This button is cylindrical, is positioned at by on the lower contact, and end face is exposed to outside the housing, presses input thereby this button can be pressed to make by lower contact generation one.Transparent rotating wheel ringwise, this runner is around button and be positioned on the encoder circuit, the runner end face is exposed to outside the housing, an at least one shell fragment that contacts with encoder circuit and a reflector are arranged on the runner, runner can be rotated, thereby make encoder circuit produce a rotation input, the light that light source sends penetrates from this transparent rotating wheel after reflective layer reflects.
Input unit of the present utility model has the rotation input and presses input, can carry out complicated input operation.
The utility model replaces rotary encoder with encoder circuit, does not need the leaded light ring simultaneously, makes input unit have less elements and smaller volume, reduces the difficulty of making and assembling.

Embodiment
Please refer to Fig. 1, it has disclosed the integrated input unit 10 of the utility model one preferred implementation.Please refer to Fig. 2, this input unit 10 comprises a printed circuit board (PCB) (pcb board) 20, a transparent rotating wheel 50, a button 60 and a housing 40.
Please in the lump with reference to figure 2, Fig. 3, an encoder circuit 21 is arranged on this pcb board 20, this encoder circuit 21 is ring-like.Also having somely by lower contact 22 and light source 23 on this pcb board 20, in the present embodiment, should be five by quantity of lower contact 22, it is cross arrangement, this light source 23 is light-emitting diode (LED), and its quantity is four, and encoder circuit 21 is around pressing lower contact 22 and light source 23.
Please in the lump with reference to figure 2, Fig. 5, transparent rotating wheel 50 is positioned on the pcb board 20, and an at least one shell fragment 55 and reflecting surface 56 of contacting with encoder circuit 21 of being used for arranged on the transparent rotating wheel 50.
Transparent rotating wheel 50 is circular, comprise a bottom 51 and from the bottom 51 the top that inner edge is upwardly extending, the cross section is inverted L shape 52.Bottom 51 is gear-like, comprises a plurality of teeth 54 that are positioned on the outer peripheral face.Be formed with many group on-slip lines 53 on the end face at top 52, so that the user can be easily with this transparent rotating wheel 50 of finger manipulation.
Please in the lump with reference to figure 2, Fig. 4, button 60 is to press lower contact 22 correspondences on a multidirectional key and the pcb board 20, and in the present embodiment, this button 60 is five to button.Button 60 is whole cylindrical, and its bottom is to being protruded with a circle flange 61.Input unit 10 also comprises an annular fixed mount 70, and the internal diameter of this annular fixed mount 70 is greater than the external diameter of button 60, and less than the external diameter of flange 61.Be extended with a plurality of connecting pins 71 downwards on this ring-like fixed mount 70, in the present embodiment, this connecting pin 71 is a L type grab 71.Ring-like fixed mount 70 is placed on the button 60 and contacts with flange 61, and grab 71 hooks pcb board 20, thereby button 60 is fixed on the pcb board 20.In other embodiments, fixed mount 70 can have a plurality of, and it is inverted L shape, and an end hook is lived flange 61, and the other end is fixedlyed connected with pcb board 20 by welding manner.
Because the structure of button 60 has been a prior art, at this it is seldom done introduction.
