The following describes described first, second Hall element 34,35 and control being connected with IC36.
As shown in Figure 9, described first, second Hall element 34,35 all is connected control with on the IC36.Especially, connect described first Hall element 34, so that export from first output circuit 71 with the first passage (channel) 70 of IC36 via control.On the other hand, connect described second Hall element 35 so that export from first output circuit 73 with the second channel 72 of IC36 via control.And timing circuit 74 is connected respectively to the described first passage 70 and first output circuit 71, and timing circuit 74 also is connected respectively to the described second channel 72 and second output circuit 73 simultaneously.Described timing circuit 74 is also connected to control system circuit (OSC) 75.
The action of described timing circuit 74 control first passages 70, first output circuit 71, second channel 72, second output circuit 73 regularly.
That is, first passage 70 is by providing driving voltage to the timing of the magnetic field of permanent magnet 51 sampling between first-INP of first Hall element 34 and first-INN.Be provided first Hall element 34 of driving voltage, output is corresponding to the Hall voltage between first-OUTP and the first-OUTN.Similarly, second channel 72 provides driving voltage by the timing of magnetic field sampling between second-INP of second Hall element 35 and second-INN.Be provided first Hall element 35 of driving voltage, output is corresponding to the Hall voltage between second-OUTP and the second-OUTN.Do not providing under the situation of driving voltage, first Hall element 34 and second Hall element 35 are not exported Hall voltage.Described timing circuit 74 only from 34 samplings of first Hall element time, drives the first passage 70 and first output circuit 71, does not in addition drive.In addition, described timing circuit 74 only from 35 samplings of second Hall element time, drives the second channel 72 and second output circuit 73, does not drive beyond this situation.
Based on the flow chart of Figure 10, control method is described below.
At first, the output signal of beginning sampling first passage 70 in step S1 then, judges whether to change, if no change then returns step S1 in step S2.By repeating step S1～S2～S3 at interval, be the sampling of the cycle carrying out the output signal of first passage 70 with α msec with α msec.If S2 changes in step, then proceed to step S3.In step S3, start not shown timer, proceed to step S4.The output signal of sampling second channel 72 in step S4, output proceeds to step S6 from the output signal of first, second passage 70,72 samplings in step S5.In step S6, behind β msec, the output signal of sampling first passage 70 judges whether to change in step S7, when changing, in step S8 timer is resetted, and starts timer once more, during no change, in statu quo proceeds to step S9.Judge at step S9 whether the stored counts time of timer passed through γ msec, if process is not then returned step S4.By repeat at interval with β msec step S4～S5～S6～S7 (～S8)～S9～S4, be the sampling of carrying out the output signal of first passage 70, second channel 72 cycle with β msec.If in step S9 the stored counts effluxion of timer γ msec, then return step S1, carry out same processing later on.
The following describes the method for operation of the input unit of forming by described structure.
The user on operation board 52 usefulness gently state of contact rotation it the time, with the permanent magnet 51 of described operation board 52 one also by same direction rotation.Therefore, the power that first, second Hall element 34,35 detects the N utmost point of permanent magnet 51 and the magnetic field μ that the S utmost point is alternately represented changes and the generation number, control IC 36 is carried out direction of rotation and rotation amount that following processing detects operation board 52 with its signal of telecommunication (Figure 11) that is transformed into square wave.
For example, with the time that changes to from the N utmost point between the S utmost point be one-period, that is, the time that falls into door bolt groove 53a with the protuberance 54a from the shell fragment 54 that falls into door bolt groove 53a once more is one-period.On the other hand, configuration flexible substrate 30 makes the detection of first Hall element 34 and second Hall element 35 only differ for 1/4 cycle.Then, when rotary manipulation dish 52, sequential as shown in figure 11, at first export square wave corresponding to the output of first Hall element 34 after, the 1/4 cycle output of staggering is controlled based on described flow chart corresponding to the square wave of the output of second Hall element 35.
That is, in step S1, the output signal of sampling first passage 70 judges at step S2 whether output changes.When step S1 and step S2, have only first passage 70 actions, second channel 72 and not shown timer are failure to actuate.If S2 is judged as no change in step, then return step S1, take a sample repeatedly with the α msec cycle until changing.If S2 changes in step, then proceed to step S3.At step S3, start not shown timer, proceed to step S4.In step S4, the output signal that obtains making 35 actions of second Hall element, second channel 72 is taken a sample, result's output in first, second passage 70,72 samplings of step S5, by analyzing the output order of first, second Hall element 34,35, the direction of rotation of differentiating operation board 52 is which positive and negative direction of rotation.
Then, in step S6, β (＜α) behind the msec, the output signal of first Hall element 34 of taking a sample judges in step S7 whether the sampling result of first passage 70 changes.When changing, proceed among the step S8, not shown timer is resetted, start timer once more and proceed to step S9.When step S7 is judged as no change, does not then reset timer and proceed to step S9.Whether the stored counts time of judging timer at step S9 has surpassed γ msec, if do not surpass, then returns step S4.By with β msec serve as repeat at interval step S4～S5～S6～S7 (～S8)～S9～S4, be the sampling of carrying out the output signal of first passage 70, second channel 72 cycle with β msec, the result of output sampling.Based on the output signal of first passage 70, the rotation amount of detecting operation dish 52.Sampling period β (＜α) msec is that the maximal rate during with the fastest rotary manipulation dish 52 of user is a benchmark, no longer than the short time in 1/4 cycle.
If the stored counts time of timer has surpassed γ msec in step S9, then return step S1.If the output signal of first Hall element 34 indeclinable situation during stored counts time γ msec means that then operation board 52 is not operated.Therefore, return step S1 this moment, and the sampling that begins the only first passage in α msec cycle is once again handled.
After, by carrying out same processing, the direction of rotation of detecting operation dish 52 and rotation amount output to the display 13 of portable phone with testing result, the rolling that shows as high brightness and being reflected.Therefore, according to the display operation input unit 14 of display 13, the first, second, third pressing detection switch 31,32,33 of conducting in good time.
Have, the differentiation of described direction of rotation and the detection of rotation amount can be carried out in controlling with IC36, also can carry out with the outside of IC36 in control based on the output signal of control with IC36 again.For example, can in the control part 11 of portable telephone 11, carry out.That is, the calculating of direction of rotation and rotation amount (or rotary speed) is not limit claim of the present invention in the unit of input unit 14 or outside the unit of input unit 14.
According to present embodiment, when the rotation amount of detecting operation dish 52, not to be output as the benchmaring rotation amount, but only be output as benchmark with first Hall element 34 with first Hall element 34 and second Hall element, 35 both sides.Therefore, obtain one click if for example think each, then as shown in figure 11, the width dimensions of door bolt groove can only form spacing corresponding to low level part in the square wave based on the output signal of first Hall element 34 in cycle.Its result, according to present embodiment, owing to do not need the high door bolt groove of dimensional accuracy, the manufacturing of inner composed component is simple, so have the advantage that can obtain productivity ratio height, cheap and small-sized input unit.
In the present embodiment, owing to intermittently drive first Hall element 34 and second Hall element 35, so can save power consumption.
In addition, if only when the output of first Hall element 34 changes, drive second Hall element 35 and carry out sampling action, then has the advantage of further saving power consumption.For example, if describe based on flow chart shown in Figure 10, during from first passage 70 sampling, timing circuit 74 drives first passages 70, first output circuit 71, drives first Hall element 34 and obtains output in step S1.Then, if do not change in the output of step S2 first Hall element 34, then returning step S1, is that the cycle is from first passage 70 samplings with α msec.Then, when the output of first Hall element 34 changes, start not shown timer at step S3, in step S4, timing circuit 74 drives the second channel 72 and second output circuits 73, drives second Hall element 35 and obtains the output (with reference to Figure 12) of second channel 72.After this, with β msec is the sampling of the cycle carrying out first passage 70 and second channel 72, if first Hall element 34 no change during γ msec, the rotary manipulation of then regarding operation board 52 as stops, by returning with α msec is the sampling processing of only carrying out first passage 70 in cycle, can further save energy consumption (have again, illustrate for schematic illustration among Figure 12, but in fact γ msec＞＞β msec).
Have again, in Figure 11, for convenience of description, be depicted as first Hall element 34 and second Hall element 35 is exported high level and low level all the time.But, if the solution of the present invention 2 described circuit, then only in the sampling period output signal.Therefore, if strict diagram is with consistent with the invention of scheme 2, the then output of ' first Hall element output of ' second Hall element ' and ' illustrates with dotted line respectively, only represents with stain when the sampling period.
Described magnetic detection part can be above-mentioned Hall element 34,35, but also can be the Hall IC of having assembled output control circuit.In addition, two Hall elements (IC) can be packaged together, and perhaps, also two Hall elements (IC) and control can be packaged together with IC.
In addition, in the above-described embodiment, not only each cycle obtains one click, also can half period acquisition click once.If constitute like this, then have the advantage easy to manufacture of permanent magnet 51.
And the groove number that also can fasten groove with a bolt or latch remains untouched, and for example the density of the N utmost point/S utmost point is 2 times, and promptly making the group number of the N utmost point/S utmost point in one week of cylindrical magnet (360 degree) is 2 times.Thus, two cycles (the N utmost point/S utmost point two groups) are identical rotation amount with above-mentioned execution mode, obtain a click feel.At this moment, after detection, extract the number of times of changes of magnetic field with control mode, if per two cycles of the rolling amount on the display are the rolling amount of an above-mentioned click, then the situation that obtains a click feel with one-period is same rolling amount, so the imperceptible difference of operator.
Input unit of the present invention is not only applicable to portable telephone, is applicable to the electronic equipment of personal computer etc. yet.
