Description
Technical field
The present invention is relevant a kind of optical mouse, particularly about a kind of optical mouse mode-changeover device that uses capacitive touch control plate.
Background technology
Optical mouse provides light source with light emitting diode (LED), but light emitting diode is power consumption very, in order to save the power consumption of mouse, the operator scheme of mouse is divided into normal running and battery saving mode, mouse is not after using after a while, to enter battery saving mode by normal manipulation mode automatically, detect the frequency that moves, reduce and detect number of times to reduce optical mouse.Mouse under battery saving mode returns back to from battery saving mode and enters normal manipulation mode after arousal function triggers.
Traditional arousal function triggers via the input button and reaches the purpose of waking mouse up.The arousal function of improvement utilizes the light of surface for computer mouse operation reflection after optics sensing integrated circuit (IC) detection and computing, judges that whether mouse is moved, and wakes the signal of mouse up with generation.
Traditional optical mouse in use, light emitting diode provides enough light source to satisfy the brightness that optics sensing IC can detect, general normal running needs the about 10～100mA of power consumption down, under battery saving mode, if optical mouse is detected the frequency that moves to be reduced, the detection number of times reduces, and still needs the about 1～10mA of power consumption, can't satisfy existing green IC notion.
According to USB specifications standard, under the battery saving mode of supporting arousal function, the average power consumption of whole mouse must be lower than 2.5mA, but traditional optical mouse is difficult for power saving, can't support arousal function with the condition that meets above-mentioned standard at battery saving mode.For satisfying the power consumption requirements of battery saving mode, traditional optical mouse only can produce arousal function by button, and can't produce arousal function by rolling mouse.
Generally speaking, when the user did not use mouse, hand all can leave mouse, and mouse can not moved, and was judging that mouse behind unused state, enters battery saving mode by normal manipulation mode automatically.And when user's desire is used mouse, all can cause mouse to move with the hand propelled mouse, and cause wake-up master, with regard to the flow process of arousal function, at first the people knows from experience touch mouse, and rolling mouse produces moving of X and Y-axis again.Traditional optical mouse only has arousal function, can't possess two-way switch mode function, under normal manipulation mode, when hand leaves mouse, can not enter battery saving mode by normal manipulation mode immediately, have the shortcoming that is difficult for power saving and under battery saving mode, support arousal function.Therefore, the present invention's switching mode device of proposing a kind of mouse satisfies power saving demand and two-way switch mode function.
Summary of the invention
One of purpose of the present invention is to propose a kind of optical mouse mode-changeover device that uses capacitive touch control plate, to reduce the power consumption of optical mouse.
To achieve these goals, the present invention proposes a kind of mode-changeover device of optical mouse, comprise: a capacitive touch control plate, be inlaid on the casing of this mouse, when hand leaves this Trackpad, produce one first capacitance change, and when this hand contacts this Trackpad, produce one second capacitance change; And a microprocessor, connect this capacitive touch control plate, to should making this mouse enter one second pattern by first capacitance change from one first pattern, and to making this mouse enter this first pattern from this second pattern by second capacitance change.
According to the present invention, a kind of mode-changeover device of optical mouse comprises that a capacitive touch control plate is inlaid on the casing of this mouse and with a microprocessor and is connected, contact or leave this capacitive touch control plate by hand, produce a capacitance change, by this microprocessor to making the mouse switch mode by capacitance change.
Utilize the optical mouse mode-changeover device of use capacitive touch control plate provided by the invention, can reduce the power consumption of optical mouse.
