As shown in Figure 1, for the present invention has the calcspar of the pointer input device primary structure of double input modes, pointer input device A of the present invention mainly includes a control computing module 1, a coordinate inductive module 2, one first simulation multiplex (MUX) module 3, one first signal Processing module 4, one second simulation multiplex (MUX) module 5 and a secondary signal and handles module 6 etc.This coordinate inductive module 2 can be accepted touch input or the input of electromagnetism pen type, control computing module 1 then utilizes the signal of simulation multiplex (MUX) module scanning touch-control or time writer input, by the signal Processing module induced signal is handled the computing of being correlated with by the microprocessor 11 in the control computing module 1 back again and exports.The single pointer input device A of the present invention just can accept two kinds of different input patterns thus.
Below do a detailed explanation with regard to each structure: these coordinate inductive module 2 inside have a touch-control sensing circuit units 21 and an electromagnetic induction circuit units 22.This touch-control sensing circuit units 21 and electromagnetic induction circuit units 22 are to adopt laminated structure, and this touch-control sensing circuit units 21 can indivedual layering settings or staggered hierarchal arrangement with the circuit of electromagnetic induction circuit units 22.This touch-control sensing circuit units 21 is a capacitance type touch-control structure in the present embodiment, particularly is a kind of projected capacitive touch structure.
This first simulation multiplex (MUX) module 3 is connected between control computing module 1 and the coordinate inductive module 2, and this first simulation multiplex (MUX) module 3 is to match with electromagnetic induction circuit units 22.Operating mode is that this control computing module 1 is to make electromagnetic induction circuit units 2 by the first simulation multiplex (MUX) module 3
2 relative loops are scanned.This first signal Processing module 4 is connected between the control computing module 1 and the first simulation multiplex (MUX) module 3.Have signal amplification circuit, automatic gain control circuit, filtering circuit in this first signal Processing module 4 ... Deng, the induced signal of electromagnetic induction circuit units 22 can be sent to after treatment control computing module 1.
This second simulation multiplex (MUX) module 5 is connected between control computing module 1 and the coordinate inductive module 2, and this second simulation multiplex (MUX) module 5 is to match with touch-control sensing circuit units 21.Operating mode is that this control computing module 1 is by the second simulation multiplex (MUX) module 5 touch-control sensing circuit units 21 relative loops to be scanned.This secondary signal is handled module 6 and is connected between the control computing module 1 and the second simulation multiplex (MUX) module 5, is sent to control computing module 1 after treatment in order to the induced signal with touch-control sensing circuit units 21.
Has at least one microprocessor 11 in this control computing module 1.This control computing module 1 is except driving first, second simulation multiplex (MUX) module 3,5, and the signal that first, second signal Processing module 4,6 can be passed back calculation process in addition, signal data output after will handling again at last, for example export a system host (for example main frame) to, utilize the integration of software in the system host and hardware and bring into play best result of use.The transmission interface that this control computing module 1 exports system host to can be wired or wireless transmission mode.
Generally speaking, pointer input device A of the present invention is when running, when if the input of electromagnetism pen type is carried out simultaneously with the touch input, the signal reception and the processing of the input of electromagnetism pen type will preferentially be continued to handle, if the signal Processing that does not have the time writer signal just can carry out the touch input, therefore the same time can not receive two kinds of induced signals and the situation of phase mutual interference.So take time writer when pointer input device A carries out the time writer input when user's hand,, make the normal operation of electromagnetism pen type input energy though during palm touching pointer input device, still can not start the touch induction.
Below just function mode of the present invention and flow process are done an explanation.As shown in Figure 2, the process flow diagram that operates for the present invention.Also please cooperate and consult Fig. 1.Step 200 enters initial state for this pointer input device A.Enter step 201 afterwards, this electromagnetic induction circuit units is carried out scanning motion, and its operating mode is operating as this control computing module 1 driving first simulation multiplex (MUX) module 3 makes the electromagnetic induction circuit units 22 of coordinate inductive module 2 carry out scanning motion.
Step 202 is judged the input signal whether time writer is arranged.If have, will carry out step 203.If no, then carry out step 205.This step operating mode is this control computing module 1 after receiving the induced signal that the first signal Processing module 4 handles by 22 responses of electromagnetic induction circuit units, carries out follow-up relative flow process by control computing module 1 according to the result.
Step 203 is carried out the data operation of electromagnetic induction signal and is handled.This control computing module 1 is after receiving the time writer input signal, still can make electromagnetic induction circuit units 22 continue to scan by the first simulation multiplex (MUX) module 3, for example carry out the scanning of each two strip antenna of the right left side of the strongest antenna, capture the signal of each antenna, the force value of calculating time writer input and the push button signalling of pen ... Deng.Should finely tune by the calculation process and the correction of internal microprocessor 11 by control computing module 1 afterwards ... Deng, calculate must coordinate and relative data such as pressure.
Then carry out step 204, the signal data output that this control computing module will be handled, return afterwards to step 201 state.
When not having the time writer input, carry out step 205, sense of touch answers circuit units 22 to carry out scanning motion.This operating mode is that this control computing module 1 driving second simulation multiplex (MUX) module 5 makes the touch-control sensing circuit units 21 of coordinate inductive module 2 carry out scanning motion.
Whether step 206, judging has touch control type input signal.If have, will carry out step 207.If no, then carry out step 201, return scanning mode to initial electromagnetic induction.This step operating mode is this control computing module 1 after receiving secondary signal and handling the induced signal that module 6 handles by 21 responses of touch-control sensing circuit units, carries out follow-up relative flow process by control computing module 1 according to the result.
Step 207 is carried out the data processing of touch-control sensing signal.This touch-control sensing circuit units 21 is handled the induced signal that obtains and is sent to control computing module 1 after module 4 is handled through secondary signal, this control computing module 1 is brought into according to the aerial signal value and obtained correct coordinate data in the formula.Carry out at last the action of step 204 again, the touch-control coordinate signal data output that this control computing module will be handled, return afterwards to step 201 state.Thus, though pointer input device of the present invention can be accepted two kinds of different input patterns, at the same time between in only handle a kind of signal Processing of input pattern.
