Comprise also on the described mouse apparatus that is exclusively used in a button that sends the locking position instruction.
The disclosed a kind of mouse of the utility model has the locking position function, and when receiving the locking position instruction, just the photodiode of cut-out or shielding mouse is luminous, cursor is fixed on screen a bit goes up motionless.
Description of drawings
Fig. 1 is a schematic block circuit diagram of the present utility model.
Fig. 2 is the emission control circuit synoptic diagram of an embodiment of the present utility model.
Embodiment is described in further detail the utility model below in conjunction with the drawings and specific embodiments.
The utility model increases a button in mouse surface, finishes the locking position function of mouse by simple circuit of key control by this.
The principle of work of optical mouse, be that a light emitting diode is arranged in optical mouse inside, the light that this light emitting diode sends, illuminate the optical mouse lower surface, a part of light from this lower surface reflected back, through one group of optical lens, be transferred to the interior imaging of a photoinduction device (little imager).Like this, when optical mouse moved, its motion track just can be registered as the coherent image of one group of high-speed capture.Utilize a special image analysis chip of optical mouse inside that a series of images that absorbs on the motion track is carried out analyzing and processing at last, by the variation of characteristic point position on these images is analyzed, judge mouse moving direction and displacement, thereby finish the location of cursor.
General mouse apparatus comprises the circuit board in shell and the shell; Button is arranged on shell, and button is electrically connected with described circuit board; Photodiode also is electrically connected with circuit board, but the hole on the light transmission shell that sends shines the outside of shell.Direction and distance that light emitting diode is used for moving according to mouse are gathered the position signalling of input, and direction that onscreen cursor moves and distance are the position signalling decisions of mouse special image analysis chip output; In the utility model, mouse special image analysis chip also link position locking signal is also handled the position signalling that back output control cursor is fixed on the output of any on the screen.
The utility model is exactly according to this principle, by on the special image analysis chip, increasing the function of the signal of checking locking position, after the locking position order that mouse is received, the special image analysis chip no longer received image after the special image analysis chip detected the locking position signal, be locked in the image before the receiving position locking, so just the locking position of mouse.The special image analysis chip receives image more again after detecting releasing locking position signal.
The mode of another locking position of the present utility model is: cut off after mouse is received the locking position order that the special image analysis chip receives new signal, light emitting diode does not send light, what the special image analysis chip received all the time like this is a two field picture, has finished the function of locking position.
Light emitting diode can be shinny when the locking position signal is high level, and this moment, the special image analysis chip can receive the image of conversion, thereby calculated the variation of position.When the locking position signal was low level, light emitting diode cannot be shinny, and this moment, the special image analysis chip did not receive the image of conversion, so realized the function of locking position.
Send the locking position command mode and have two kinds: the one, utilize existing mousebutton, for example continuity point right click n expression locking position order is down finished under the continuity point right click m and is removed the locking position function.The 2nd, can be on the surface of mouse at the function button that increases locking position.
Be illustrated in figure 1 as schematic block circuit diagram of the present utility model, mouse moving is converted into the position signalling of the input of mouse special image chip by photodiode, mouse special image analysis chip is processed into the position signalling of input the position signalling of output, the position signalling of output is the mobile direction and the angle of the onscreen cursor that becomes with angular transition of the direction of mouse moving, when the position signalling of output changed, cursor just moved on screen.When locking position signal input mouse special image analysis chip, the position signalling conductively-closed of input because the locking position signal is constant, so the position signalling of output this moment is also constant, thereby has realized the locking of mouse position.
Be illustrated in figure 2 as the emission control circuit synoptic diagram of an embodiment of the present utility model, the light emitting diode that is used to gather mouse moving direction and distance is serially connected in a transistorized collector, this transistorized grounded emitter, base stage is by the locking position instruction control.When locking position instruction arrived, triode was in off state, and light emitting diode is disconnected can not be luminous, and mouse moving just can not gathered like this, and the position signalling of input that arrives mouse special image chip is constant, thereby had realized the locking of mouse position.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
