The first and second Hall elements 34 and 35 for the rotation information are mounted on the spot. On the other hand, the control IC 36 is mounted between the first and third lower detection switches 3 1 and 3 3 . Further, in order to detect the rotational direction of the operation dial 52, and to ensure the high resolution function, the positions of the first and second Hall elements 34 and 35 must be spaced apart from each other. Therefore, the second rising piece 23 on the side of the bottom plate 20 is inserted into the fixing hole 30 a of the flexible substrate 30, and the other second standing piece 24 is also fitted to the flexible substrate 30.

Next, as shown in Fig. 6A, the outer peripheral surface of the permanent magnet 5 1 is alternately arranged in an N-pole and an S-pole to be equally divided into 12 (or 6 equal parts. Therefore, the outer peripheral surface of the permanent magnet 5 1 may have an opposite polarity.

As described in Fig. 8, the sensor springs 5 4 are formed by folding a spring plate having a slightly rectangular shape into a reverse V shape, and a projection 54a is formed by projecting in the outer edge portion. The protrusion 54a' is intermittently elastically fitted with the radial pin groove 53a of the front dial 52, and the operator has an operational feeling (keystroke feeling). Next, the operation dial unit 40' Figure 8 shows that the 4 2 b 〇 为 为 ° ° ° ° ° ° ° ° ° ° ° ° ° ° ° ° ° ° ° ° ° ° ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( 3. The pair of matching shafts 43b and 43a of the original (4) repairing (more) originals 41 are inserted into the first shaft supporting holes 21a and 22a of the first rising pieces 21 and 22 of the bottom plate 20, respectively, to form a support for operating the dial. The unit 40 is rotatable. Also via this support, the operation projection 4 2 b formed at the center of the lower surface of the side arm portion 42 of the frame 4; is positioned just above the first lower detection switch 3 1 . As shown in FIGS. 5 and 8 , the integral operation button 60 0 connects the two side edge portions of the pair of curved operation portions 61 and 62 with the connection portions 63 and 64 to form an integrator. And having a planar shape that is possible to be fitted to the operation dial unit 40.

The position is just above the detection switches 3 2 and 3 3 at the second and third sides respectively. Next, the wiring of the first and second Hall elements 34 and 35 and the control IC 36 will be described. As shown, both the first and second Hall elements 34 and 35 are connected to the control port C 36. The first Hall element 34 is rewired via the first channel 70 of the control IC 36. Up to the first output circuit 7 1 and then to the output terminal. On the other hand, the second Hall element 35 is rewired via the second channel 7 2 -13 - 129897 [J^V3 to the second output circuit 7 3 and then to Output. Again The first channel 7 〇 and the first output circuit 7 1 are connected to the timing circuit 74, respectively, and the second channel 72 and the second output circuit 73 are also connected to the timing circuit 74. The circuit 74 is also connected to the control system circuit (〇SC) 75. The timing circuit 74 is connected to the first channel 70, the first output circuit 71, the second channel 72, and the second output circuit 73. The timing of the action is controlled. That is, the first passage 70 supplies a drive voltage between the first -INP and the first -INN terminals of the first Hall element 34 at the time when the permanent magnet 51 is to be sampled by the magnetic field change. The first Hall element 34' to which the driving voltage is supplied has an induced Hall voltage output between the first 0-UTP and the first -0-UTN terminals. Similarly, the second passage 72 supplies a driving voltage between the second ININ and the second INN terminals of the second Hall element 35 when the permanent magnet 51 is to be sampled by the magnetic field change. The second Hall element 35 to which the driving voltage is supplied has an induced Hall voltage output between the second-0UTP and the second -0UTN terminals. When the drive voltage is not supplied, the first Hall element 34 and the second Hall element 35 have no Hall voltage output. Therefore, the timing circuit 74 drives the first channel 7〇 and the second output circuit 7 1 only when the first Hall element 34 is sampled, and does not drive at other points. Further, the timing circuit 74 drives the second channel 7 2 and the second output circuit 73 only when the second Hall element 35 is sampled, and does not drive at other points. Next, the control method will be described based on the flowchart of Fig. 1 . First, after the start, the output signal of the first channel 70 is sampled in step S1, and then it is judged whether there is a change in step S2, and if there is no change, the process returns to step S1. -14 - 1258971 For the 3rd to 3rd revision (more), the steps S 1 to S 2 to S 1 are repeated at intervals of a m s e c , so the output signal of the seventh channel is sampled at the period of a m s e c . If there is a change in step s', then the process proceeds to step S3. At step s 3, the timer not shown in the figure starts counting, and proceeds to step S4. The output signal of the second 72 is sampled in step s4, and the output signals of the first, second, and second 70, and 72 samples are outputted in step S5, and then the process proceeds to step S6. After S6, the output signal of the first channel 70 is sampled after /3 msec, and the change is judged at S7. If there is a change, the timing is re-started in step s8; In the case of change, proceed directly to the step of determining in step S9 whether or not the cumulative count of the timer has passed 7 msec. If not, the process returns to step S4. Steps S4 to S5 to S6 to S7 (~S8) to S9 are repeatedly executed at intervals of /3 msec. Therefore, the output signals of the first channel 70 and the second 72 are sampled at a period of /3 msec. In step S9, if the cumulative timing of the timer has passed r ni s e c, the process returns to step s 1, and then the processing is performed. Next, an operation method of the input device constructed as described above will be described. The user gently touches the upper surface of the operation dial 52 2 and rotates the permanent magnet 5 1 integral with the aforementioned operation dial 52 to be in the same direction. Therefore, the magnetic field strength change and the number of changes of the N pole and the S pole of the permanent magnet 5 1 are known, that is, the first and second Hall elements 3 4 and 3 5 are known, and then converted into a rectangle by the control IC 36. The electric signal (|picture) of the wave is detected by the following processing, and the direction and amount of rotation of the operation dial 52 are detected. For example, the elapsed time from the N pole to the S pole is called a period. If the channel step in the 1st pass is more than the S9 〇 right 尙 S S4 channel timing line, the rotation of the detected 111 to the turn # -15 - 1258971 9b·力一3日修 (策) The original feel of the spring 5 4 protrusion 5 4 a from falling into a bolt groove 5 3 a and then falling again into the adjacent pin groove 5 3 a The elapsed time is treated as a cycle. On the other hand, the arrangement of the flexible substrate 30 is such that the detection signal time difference between the first Hall element 34 and the second Hall element 35 is exactly 1/4 cycle. Therefore, after the operation dial 52 is rotated, as shown in the timing chart of Fig. 1, first, the rectangular wave output corresponding to the output of the first Hall element 34 is delayed by /4 cycles. It is a rectangular wave output corresponding to the output of the second Hall element 35, and then the control is performed according to the aforementioned flowchart. That is, the output signal of the first channel 70 is sampled in step S1, and it is judged in step S2 whether or not the output changes. When step S1 and step S2 are executed, only the first channel 70 is activated, and the second channel 72 and the timer ’ not shown in the figure are not operated. In step S2, if it is determined that there is no change, the process returns to step S1' to repeatedly sample in the period of a m s e c until there is a change. If there is a change in step S2, the process proceeds to step s3. In step S3, a timer not shown in the figure starts counting, and proceeds to step S4. In step S4, the second Hall element 35 is operated and the output signal is sampled by the second channel 72, and the output signals of the first and second channels 7A and 72 after sampling are outputted in step S5. The output order of the first and second Hall elements 3 4 and 3 5 is analyzed, and it is determined that the rotational direction of the operation dial 52 is forward or reverse. Next, in step S6, the output signal of the first Hall element 34 is sampled by cold (<a) m s e c, and it is judged in step S7 whether or not the sampling result of the first channel 70 is changed. If there is a change, the process goes to step S8, and the timer not shown in the figure is reset to be restarted, and the process proceeds to step S9. And -16 - ~ ~ one - one ------- I __ 1258971 ^ ΛΛ丨 repair (gas) original; in step S 7, if it is judged that there is no change, do not return the timer and go directly to Step S9. In step s9, it is judged whether or not the accumulated count of the timer has exceeded r m s e C, and if not, the process returns to step s 4. Steps S 4 to S 5 to S 6 to S 7 (~S 8 ) to S 9 to S 4 are repeatedly executed at intervals of 10,000 msec. Therefore, the output signals of the first channel 70 and the second channel 7 2 are at the point msec. The cycle is sampled and the sampled result is output. According to the signal output of the first channel 7 ,, the amount of rotation of the operation dial 52 can be detected. The sampling period 々 (< a ) m sec is used as a reference for the maximum speed at which the user operates the dial 52 to rotate the fastest, and how long it is longer than the 1/4 cycle time. • If the cumulative time of the timer has exceeded 7 m s e c in step S 9 ', then return to step S 1 . If the output signal of the first Hall element 314 does not change between the accumulation timings r msec , it means that the operation dial 52 is not operated. Therefore, in this case, returning to step S1, the sampling process of the first channel is started again with the period a m s e c . Thereafter, the rotation direction and the amount of rotation of the operation dial 52 are detected by the same processing, and the detection result is output to the display 13 of the mobile phone, and the scrolling of the highlight display or the like is performed. Therefore, the input device 14 is operated in accordance with the display of the display 13 and the first, second, and third lower detection switches 3 j , 32 , and 3 3 are appropriately turned on, thereby achieving control of the display. purpose. Further, the determination of the rotational direction or the detection of the amount of rotation may be performed by the control IC 36 or may be performed outside the control IC 36 in accordance with the output signal of the control IC 36. For example, it may be executed in the control unit 1 of the mobile phone n. That is to say, the determination of the direction of rotation or the calculation of the amount of rotation (or the speed of rotation) is performed in the unit of the input device 14, or in the month of -17 - 1258971 (more) Except for the execution of the unit 4, the scope of the invention is not limited. According to the present embodiment, the detection of the amount of rotation of the operation dial 52 is not based on the output of both the first and second Hall elements 34 and 35, but only the i-th Hall. The output of the component 34 is detected as a reference. Therefore, for example, if one keystroke is to be obtained in each cycle, the width and the pitch of the pin groove are shown by the portion of the rectangular wave according to the output signal of the first Hall element 34 as shown in FIG. Correspondence can be formed. As a result, according to the present embodiment, the bolt groove does not require high dimensional accuracy, and the manufacture of internal parts is simple. Thus, an advantage of the present invention is that a small input device that is highly productive and inexpensive can be obtained. Further, in the present embodiment, since the first Hall element 34 and the second Hall element 35 are intermittently driven, power consumption can be saved. Further, if the second Hall element 35 is driven to perform the sampling operation only when the output of the first Hall element 34 is changed, the advantage is that power consumption can be further saved. For example, according to the flowchart shown in FIG. 10, when the output signal of the first channel 70 is sampled in step S1, the timing circuit 74 drives the first channel 70 and the first output circuit. The first Hall element 34 is also driven to obtain an output. Next, in step S2, it is judged that if the output of the first Hall element 34 has not changed, the process returns to step S1, and the first channel 70 is sampled at a period of a m s e c . Next, when the output of the first Hall element 34 changes, a timer that is not shown in the figure starts to be counted in step S3, and then the step S4, the timing circuit 74, the second channel 7 2 and the The output circuit 7 3 is driven, and the second Hall element 35 is also driven to obtain the output of the second channel -18 - 1258971 - one ..... (Refer to Figure 12). Thereafter, sampling is performed on the first channel 70 and the second channel 72 at a period of /3 msec, and if the output signal of the third Hall element 34 does not change between rmse C, it is regarded as the rotation of the operation dial 5 2 . Has stopped, and then returned to the processing of the first channel 7 以 sampling in the amsec cycle; through this, the power consumption can be saved again (again, the picture of the brother 12 is for the sake of explanation, the figure is not simplified, the actual Up/^msec>>y5 msec) ° Further, in Fig. 11, for convenience of explanation, the first Hall element 34 and the second Hall element 35 usually have outputs of High and Low to be illustrated. However, according to the circuit related to the invention described in the second application of the present application, the signal is output only during the sampling period. Therefore, in order to comply with the invention related to the second application, the "first Hall element output" and the "second Hall element output" in the figure should be more strictly indicated by dotted lines, only in The sampling period has black dots. The magnetic field detecting method may be performed by using the Hall elements 34, 3, or by using a so-called Hall 1C in which the output control circuits are assembled. Further, two Hall elements (1C) may be formed as one package, or two Hall elements (1C) and control 1C may be formed as one package. Further, the above-described embodiment is not limited to the key hitting feeling obtained once per cycle, and the key hitting feeling may be obtained once every half cycle. Such a configuration has an advantage that the manufacture of the permanent magnet 51 is easy.
