Again for example; Suppose when the user is left-handed with rotatable parts (for example rotation axis); The first electroconductive elastic sheet A and earth terminal 210 conductings; The second electroconductive elastic sheet B is from becoming and earth terminal 210 conductings with 220 conductings of adjustable resistance terminal, and when making the magnitude of voltage of the electroconductive elastic sheet A that wins be low level, the magnitude of voltage of the second electroconductive elastic sheet B becomes low level by high level.
Again for example; Suppose as user during rotatable parts (for example rotation axis) dextrorotation; The first electroconductive elastic sheet A and 220 conductings of adjustable resistance terminal; The second electroconductive elastic sheet B is from becoming and earth terminal 210 conductings with 220 conductings of adjustable resistance terminal, and when making the magnitude of voltage of the electroconductive elastic sheet A that wins be high level, the magnitude of voltage of the second electroconductive elastic sheet B becomes low level by high level.
Concrete menu operation scene for example below.
For example, under no menu state, the user pushes and flies for 1 time to unclamp behind the shuttle key 200 (being equivalent to push rotatable parts (for example rotation axis)); At this moment; Suppose that the magnitude of voltage that control chip monitors its 3rd control port 113 becomes low level (that is, the magnitude of voltage of the 3rd electroconductive elastic sheet A becomes low level by high level) by high level, at this moment; What 100 of control chips thought that the user imports is the instruction of ejecting submenu, and control chip 100 ejects main menu on television screen.
Under no menu state, the user push and fly 200 several seconds of shuttle key (as 2 seconds or more than) after unclamp again, at this moment; Suppose that the magnitude of voltage that control chip 100 monitors the 3rd control port becomes low level by high level; Become high level (that is, the magnitude of voltage of the 3rd electroconductive elastic sheet A becomes low level by high level, becomes high level after the several seconds again) after several seconds again; What this moment, 100 of control chips thought that the user imports is the instruction of ejecting the information source menu, and control chip 100 ejects the information source menu on television screen.
Behind popup menu; The user flies shuttle key 200 (being equivalent to left-handed or right rotation dynamic component (for example rotation axis)) as if left-handed or dextrorotation; At this moment; Suppose that the magnitude of voltage that control chip 100 monitors first control port 111 is a low level, the magnitude of voltage of second control port 112 becomes low level by high level; Perhaps; Suppose that the magnitude of voltage that control chip 100 monitors first control port 111 is a high level; The magnitude of voltage of second control port 112 becomes low level by high level; What this moment, 100 of control chips thought that the user imports is the function choosing-item selection instruction, and control chip 100 display highlighting on television screen switches at each function choosing-item and moves.
After cursor moves to certain function choosing-item to be operated; If the user pushes 1 time and flies shuttle key 200; Suppose that the magnitude of voltage that control chip 100 monitors its 3rd control port 113 becomes low level by high level this moment; What this moment, 100 of control chips thought that the user imports is to get into the function adjustment state, and control chip 100 gets into the function adjustment state.After getting into this function adjustment state, the user is if left-handed or dextrorotation flies shuttle key 200, and what this moment, 100 of control chips thought that the user imports is the function regulating command, the control chip 100 corresponding corresponding values of consult volume of regulating these functions.After function parameter adjustment was accomplished, if the user pushes 1 time singly-bound and flies the shuttle key, this moment, 100 of control chips were thought the instruction that affirmation value of consult volume adjustment that the user imports is accomplished, control chip 100 function selecting states.
When cursor moves to " withdrawing from " option; If the user pushes and flies shuttle key 200 once; Suppose that the magnitude of voltage that control chip 100 monitors its 3rd control port 113 becomes low level by high level this moment; What 100 of control chips thought that the user imports is to return the Previous Menu instruction, and control chip 100 returns Previous Menu.If the user pushes and flies 200 several seconds of shuttle key to unclamp after (for example more than 2 seconds); Suppose that the magnitude of voltage that control chip 100 monitors its 3rd control port 113 becomes low level by high level this moment; Become high level after several seconds again; What 100 of control chips thought that the user imports is to withdraw from menu instructions, and control chip 100 withdraws from menu, and the OSD on this moment television screen disappears.
Under no menu state, if the left-handed or dextrorotation of user flies shuttle key 200, at this moment, suppose that the magnitude of voltage that control chip 100 monitors first control port 111 is a low level, the magnitude of voltage of second control port 112 becomes low level by high level; Perhaps; Suppose that the magnitude of voltage that control chip 100 monitors first control port 111 is a high level; The magnitude of voltage of second control port 112 becomes low level by high level; What this moment, 100 of control chips thought that the user imports is channel plus-minus (or volume plus-minus) instruction, and at this moment, control chip 100 carries out channel plus-minus (or volume plus-minus).
Be appreciated that above-mentioned menu operation mode is a kind of giving an example, in practical application, also possibly have the menu operation mode certainly, give unnecessary details no longer one by one here.
Therefore present embodiment is integrated into one with the television set operation push-button and flies the shuttle key, flies the rotation of shuttle key and pushes to make the magnitude of voltage of control chip change, and then realize the input of menu operation instruction.This button is integrated mode and has been reduced number of keys greatly, helps the maintenance assembling, also helps designing simultaneously profile attractive in appearance.
