Embodiment

See also Fig. 2, Fig. 2 is the synoptic diagram of the preferred embodiments of the utility model touch panel device.Touch panel device 1 comprises touch panel 10, light conductor 20, main part 30 and a plurality of button 40.Touch panel 10, light conductor 20 and main part 30 are provided with from top to bottom in regular turn, and a plurality of button 40 silk-screens are arranged on a side of touch panel 10.

Please consult Fig. 3 and Fig. 4 again, Fig. 3 is the perspective view of the utility model light conductor, and Fig. 4 is the perspective view after the utility model light conductor assembles with touch panel.Light conductor 20 comprises LGP 202 and leaded light post 204, and leaded light post 204 is arranged on the LGP 202, and light conductor 20 is oppositely arranged with a plurality of buttons 40, and leaded light post 204 is a hollow structure.

Please continue to consult in the lump Fig. 5, Fig. 6 and Fig. 7, Fig. 5 is the structural representation that the utility model touch panel device is not installed touch panel, and Fig. 6 is the structural representation after the utility model light conductor assembles with main part, and Fig. 7 is the local enlarged diagram of Fig. 6.Main part 30 comprises printed circuit board (PCB) (not indicating) and light source 301, and light source 301 is arranged on the printed circuit board (PCB), and leaded light post 204 is provided with near light source 301 and light source 301 is embedded in the leaded light post 204.In the present embodiment, light source 301 is specially LED.
