Abstract
A coordinate position indicator with keys belongs to the computer peripheral equipment field. The main technical points of the present invention are that: the indicator comprises at least one function key module; by controlling the conducting or disconnecting state of a key switch in the function key module, voltage values of received signals of a micro-control processor are locked; the micro-control processor transmits corresponding control signals to a computer according to the locked voltage values, and then the computer completes corresponding software switching functions. The present invention has the advantages that: the structure is simple and practical, can be applied to electromagnetic, photoelectric and acoustic wave position indicators, can define functions needing to be switched at option, and is wide in application range.
Description
Technical field
The present invention relates to a kind of coordinate position indicator of finishing the track input, relate in particular to a kind of coordinate position indicator that can carry out the function switching, belong to field of computer peripherals with button.
Background technology
Coordinate position indicator generally is used for the computer peripheral of character and track input, comprises common handwriting input pen, computer graphics pen, mouse or the like.Coordinate position indicator mainly uses three kinds of technology at present: electromagnetic technique, technology of acoustic wave and photoelectric technology.
The user often need carry out blocked operation between the various functions of application software when using these coordinate position indicators, the mode of switching is to select corresponding function menu with coordinate position indicator at the software operation page usually, directly switches.In recent years, Japan Wacom company has created a kind of electromagnetic type coordinate position indicator, it is identical by the two ends at coordinate position indicator structure to be set respectively, the resonant circuit that resonance frequency is different, principle according to the electromagnetic type coordinate position indicator, make an end of this coordinate position indicator be used for the handwriting tracks input, the other end is used for handwriting tracks to be removed, thereby the function that reaches between " pen " and " erasing rubber " is switched.But the improved this coordinate position indicator of Wacom company needs the resonant circuits that add more, has improved production cost of products, and can only be applied to the electromagnetic type coordinate position indicator.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of coordinate position indicator that has function button, can lock coordinate position indicator by function button and finish different software functions, reaches to carry out the purpose that function is switched rapidly.
The technical scheme that technical solution problem of the present invention is adopted is: comprise a function button module at least, the circuit unit that forms by keyswitch K2 and capacitor C 21 polyphones with by resonant capacitance C22 and inductive coil L2 and connect the resonant circuit polyphone composition function key-press module of forming, the conducting of the keyswitch K2 in the function button module or off-state lock the magnitude of voltage of microcontroller processor received signal.
Function button is not limited to be arranged on the afterbody of coordinate position indicator.
The present invention also provides a kind of technical scheme to comprise a function button module at least; The magnitude of voltage of the conducting of the keyswitch K3 in the function button module or off-state locking microcontroller processor received signal, keyswitch K3 and resistance R 3 composition function key-press modules, the termination power VCC of keyswitch K3, the other end is connected with an end of resistance R 3, the other end ground connection of resistance R 3.
The invention has the beneficial effects as follows simple and practically, can be applicable to electromagnetic type, photo-electric and sound wave type coordinate position indicator, can arbitrarily define needs the function switched, applied range.

Specific embodiment
In the principle of work block diagram of Fig. 1, coordinate position indicator of the present invention has function button module 1, comprises keyswitch in the function button module 1.The control keyswitch is conducting or off-state, keyswitch state in the key-press status detection module measuring ability key-press module, locking and transmission and the corresponding magnitude of voltage of keyswitch state are given the microcontroller processor, then, give computing machine by the microcontroller processor by the PORT COM transfer control signal, the function of finishing computer application software is switched.In order to realize the switching of various software function, the invention is not restricted to comprise a function button module 1.
Fig. 2 adopts an exemplary embodiment of electromagnetic technique for the present invention, keyswitch K2, capacitor C 21 and formed function button module 1 of the present invention together by the resonant circuit that resonant capacitance C22, inductive coil L2 form, be connected with the other end of keyswitch K2, capacitor C 21 respectively behind keyswitch K2 and capacitor C 21 polyphones in the function button module 1, resonant capacitance C22 and inductive coil L2 parallel connection.When pushing button K switch 2, keyswitch K2 is locked as conducting state, and when pushing button K switch 2 once more, keyswitch K2 is locked as off-state again.Therefore, when needs carry out the software function switching, K switch 2 pushes button, lock it and be conducting state, thereby the capacitance of resonant circuit is changed, cause the variation of resonance frequency and phase place, function button module 1 is transmitted the resonant circuit phase signal of this moment and is given phase detecting circuit, position detector detected phase value in the phase detecting circuit, phase detecting circuit transmits with phase value corresponding voltage value signal and gives the microcontroller processor, transmit corresponding control signal by the microcontroller processor by PORT COM again and give computing machine, Computer Processing switches to corresponding software function.The present invention is when adopting electromagnetic technique work, and the position detector of phase detecting circuit has been finished the function of keyswitch K2 locking conducting in the measuring ability key-press module 1 or off-state, therefore, is equivalent to key-press status detection module 2.Adopt the coordinate position indicator of technology of acoustic wave to adopt the principle of work of electromagnetic technique identical with the present invention.
Fig. 3 adopts an exemplary embodiment of photoelectric technology for the present invention, and keyswitch K3 and resistance R 3 have been formed function button module 1 of the present invention, in the function button module 1 behind keyswitch K3 and resistance R 3 polyphones, and a termination power VCC, other end ground connection.In this embodiment, the conducting of keyswitch K3 and disconnection, directly changed the magnitude of voltage at resistance R 3 two ends, therefore need not key-press status detection module 2 can be directly passed to the corresponding voltage value signal microcontroller processor, transmit corresponding control signal by the microcontroller processor by PORT COM again and give computing machine, Computer Processing switches to corresponding software function.
Fig. 4 comprises the schematic appearance of a function button for the present invention, and as shown in the figure, function button 3 places the afterbody of coordinate position indicator shell 4 of the present invention, and track input end 5 is used for the input of computing machine track.When using coordinate position indicator of the present invention, only need press function button 3, promptly switch to corresponding software function.Coordinate position indicator of the present invention also can comprise two and above function button 3, and the afterbody that the position is not limited to shell 4 of the present invention is set.
The present invention has improved the electromagnetic type coordinate position indicator and carried out the mode that software function is switched, and is simple in structure, makes the user more convenient to operate simple and easy, solved sound wave type and photo-electric coordinate position indicator simultaneously and carried out the problem that software function is switched.
