mm、厚さ0.02mmの磁歪伝達媒体を使用している。 The magnetostrictive transmission media 221a and 221b generate and propagate magnetostrictive vibration waves by applying a change in magnetic flux, and also cause a change in magnetic flux.They can be used if they are ferromagnetic, but because they generate strong magnetostriction vibration waves. A material with a large magnetostrictive effect, such as an amorphous alloy containing a large amount of iron, is particularly desirable. or,
A material with a small coercive force that is difficult to magnetize even when a magnet is brought close to it is preferable. Examples of amorphous alloys include Fe 67 Co 18 B 14 Si 1 (atomic %), Fe 81 B 13.5 Si 3.
5 C 2 (atomic %) etc. can be used. Magnetostrictive transmission medium 22
1a and 221b have an elongated shape, and the cross section is preferably a rectangular thin strip or a circular linear shape, and in the case of a thin strip, the width is about several mm and the thickness is from several micrometers to several tens of micrometers.
It is easy to manufacture and has good properties. Amorphous amorphous alloys can be manufactured into thin pieces with a thickness of 20 to 50 μm, so they can be cut into thin strips, and linear ones with circular cross sections can also be made, so they can be used as is. . In this example, the width 2 is made of Fe 81 B 13.5 Si 3.5 C 2 (atomic %).
A magnetostrictive transmission medium with a thickness of 0.02 mm and a thickness of 0.02 mm is used.

This is for applying a bias magnetic field parallel to the longitudinal direction to the wound portions of the coils 223a and 223b of 1a and 221b. The reason for applying the bias magnetic field in this manner is to enable generation of large magnetostrictive vibration waves with a small amount of current, and to specify the generation position of the magnetostrictive vibration waves. That is, the magnetostrictive transmission medium 22
The electromechanical coupling coefficients (coefficients that indicate conversion efficiency from mechanical energy to electrical energy or from electrical energy to mechanical energy) of 1a and 221b are maximum at a certain bias magnetic field, as shown in Fig. 5, for example. Therefore, by applying such a magnetic bias to the wound portions of the first coils 223a and 223b, magnetostrictive vibration waves can be efficiently generated.

域となる。 The second coils 225a, 225b are respectively disposed on the reinforcing members 222a, 222b over a wide range of the magnetostrictive transmission media 221a, 221b. The coils 225a and 225b are wound in the same direction (left-handed in this embodiment) on the respective magnetostrictive transmission media 221a and 221b, and are connected in series so that the polarities of the connections are opposite to each other, so that no external induction and noise cancel each other and are weakened. The winding pitch of the coils 225a and 225b is preferably large in order to increase the induced electromotive force; for example, in this embodiment, the winding pitch is 7 turns/cm on average. In addition, in order to compensate for the decrease in the induced voltage due to the attenuation of the magnetostrictive oscillatory waves, the coils are wound gradually more densely from one end on the side close to the first coil 223 to the other end on the opposite side. It's okay. This second
Coils 225a and 225b are magnetostrictive transmission medium 221

用しても良い。 FIG. 7 illustrates an example of a temporal change in the induced electromotive force generated in the second coils 225a and 225b, with the time when the pulse current is applied to the first coil 223 being t=0. As shown in the figure, the amplitude of the induced electromotive force changes immediately after time t=0 and from time t 0 to t 1 ~
It becomes larger after t 2 seconds and becomes smaller at other times. The reason why the amplitude of the induced electromotive force becomes large immediately after time t= 0 is due to the electromagnetic induction effect between the first coil 223 and the second coils 225a and 225b. The amplitude of the induced electromotive force (induced voltage due to magnetostrictive vibration waves) increases because the magnetostrictive vibration waves generated in the winding portion of the first coil 223 are transferred to the magnetostrictive transmission medium 221.
This is because the electromechanical coupling coefficient becomes large at that portion after propagating through a and 221b and reaching the vicinity directly below the identification magnet 108. If the magnet 108 is located on another frame 110, that is, the magnetostrictive transmission medium 221
When the magnets a and 221b are at different positions along the longitudinal direction, the induced voltage due to the magnetostrictive vibration waves also moves on the time axis accordingly. Therefore, from time t 0 to t 1 ~
By measuring the time up to t2 , the position of the magnet 108, that is, the distance l can be calculated. As the propagation time for calculating the position, for example, the seventh
As shown in the figure, the time point t3 when the amplitude of the induced voltage becomes smaller than the threshold value -E1 , the time point t4 when it becomes larger than the threshold value E1 , or the zero crossing point t5 may be used. .

４００へ送出される。 The induced electromotive force generated in the second coils 225a and 225b described above is input to the pulse detector 306. The pulse detector 306 is composed of an amplifier, a comparator, etc., and the induced electromotive force is, for example, the threshold value mentioned above.
While E is greater than 1 , that is, when the positive polarity portion of the induced voltage is detected, the output is set to high level. When the control circuit 301 reads this high level signal via the input buffer 307, the control circuit 301 outputs the signal from the output buffer 3.
A stop signal is output to the counter 304 via the counter 304 to stop counting. At this time, the counter 30
4, a digital value corresponding to the time from the time when the pulse current is applied to the first coil 223 until the induced voltage due to the magnetostrictive vibration wave appears in the second coils 225a, 225b is obtained. Further, this value corresponds to the distance l from the first coil 223 to the magnet 108 because the magnetostrictive vibration wave travels at a speed of about 5000 m per second. The distance l obtained in the counter 304 as a digital value in this way,
That is, the position of the magnet 108 is read into the control circuit 301 via the input buffer 307 and further sent to the processing device 400.

Since it is equipped with a processing device that determines the type of menu sheet, it is possible to identify the type of the menu sheet simply by placing the menu sheet on the input board. Since the position of the installed magnet can be detected with extremely high resolution and accuracy, it is possible to replace a very large variety of menu sheets one after another without having to input identification codes using other input means as in the past. This method has advantages such as being able to provide a menu sheet input device that can be used and has extremely good operability.
