(Technical Field) The present invention relates to a menu sheet input device that facilitates the exchange of many types of menu sheets. (Problems with the prior art) Conventionally, a menu sheet in which input menus such as a large number of pictures, figures, and letters were printed at predetermined positions on a sheet t made of paper, plastic film, etc., was created using a pressure-sensitive pad, electromagnetic coupling, etc. A device that can be placed on an input board and input by selecting one of the input menus on the input menu by avoiding contact with the input menu on the menu sheet l- with an indicating pen or the like. was there. However, in such a device, menu screen 1
When there are many types of ~, the code signal etc. indicating the type must be input using another input means, such as a keyboard, which may make the operation complicated when inputting from multiple menu sheets. Another problem was that it required extremely difficult work for inexperienced people, especially young children. (Object of the Invention) In view of the above-mentioned conventional problems, the present invention provides a menu sheet input device that can identify the type of menu sheet by simply placing the menu sheet on a manual board. The purpose is to (Embodiment of the Invention) The drawings show an embodiment of the present invention. In the figure, 100 is a menu sheet, 200 is an input board, 30
0 is an identification circuit, 400 is a processing device, and 500 is an input pen. The menu sheet 100 has a menu portion 1 on the surface 102 of a sheet body 101 made of paper, plastic film, etc.
03, and an identification mark portion 105 is provided on the back surface 104 thereof. The menu part 103 is constructed by printing a large number of input menus 106 such as one picture, one figure, and nine characters in a predetermined position, and covers almost the entire surface of the front surface 102 except for one side 107. The identification mark section 105 is made up of one or more thin plate-shaped identification magnets 108 attached on the back surface 104, and the distance (position) from the reference position 109 to the identification magnet 108 or the identification Depending on the number of magnets 108 or a combination thereof, the menu sheet 100
However, in this example, the distance (
position). The identification mark portion 105 is formed at a portion of the back surface 104 corresponding to one side 107 of the front surface 102. The input board 200 has a housing 201 and a rose 202 made of non-magnetic metal or the like and is approximately the same size as the menu sheet 100, and has a menu manual section 210 and an identification mark detection section 2 inside.
It is equipped with 20. The menu personnel department 210 sends 100 to the menu sheet 202, . This is for detecting the position of the input menu 106 specified by placing the input ben 500 on one of the input menus L-106 placed at a height of 1 m, and is approximately the same area as the menu part 103. It consists of a known pressure-sensitive tablet, electromagnetic coupling tablet, etc., which has an input range of . Note that the detailed configuration and operation thereof are well known and will therefore be omitted. The identification mark detecting section 220 detects magnetostrictive transmission media 221a, 2
21b, reinforcing members 222a, 222b, and the first ffi! The transducer 2 is composed of a coil 223, a magnetic generator 1 for specifying a reference position, such as a magnet 224, and a second electromagnetic transducer 2, e.g. coils 225a and 225b. 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. Although they can be used if they are ferromagnetic, they generate strong magnetostriction vibration waves. In order to achieve this, it is particularly desirable to use a material with a large magnetostrictive effect, such as an amorphous alloy containing a large amount of iron. In addition, a material with a small coercive force that is difficult to magnetize even if the magnet is brought close to it is preferable. Examples of amorphous alloys include Fe Go [3Si (atomic%), Fe8167
1814 1 BSiC (atomic %), etc. can be used. 13.5 3.5 2 The magnetostrictive transmission medium 221a, 221b has an elongated shape, and its 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 11 m and the thickness is about several liters. μ ~ number 1
A thickness of about 0 μm is easy to manufacture and has good characteristics. Due to the manufacturing process, Alnoas alloy can be made into thin pieces with a thickness of 20 to 50 μm, so it can be cut into thin strips, and linear pieces with circular cross sections can also be made, so you can use this as is. good. In this example, a magnetostrictive transmission medium made of FeB51C (81 13.5 3.5 2% atoms) with a width of 2 mm and a thickness of 0.021 mm is used. The magnetostrictive transmission media 221a and 221b are housed inside elongated cylindrical reinforcing members 222a and 222b made of synthetic resin or the like, respectively, and are arranged substantially parallel to each other. First, the first coil 223 is disposed on the reinforcing members 222a and 222b at one end of the magnetostrictive transmission medium 221a and 221b. The coils 223a and 223b corresponding to the respective magnetostrictive transmission media 221a and 221b are wound in opposite directions, so that when a current is applied to the coils 223, electricity is generated from each coil 223a and 223b. □Noise and external guidance cancel each other out - C is weakened. The number of turns is one in the illustrated example, but the number of turns may be two or more. This first coil 223 generates an instantaneous magnetic field fluctuation and transmits the magnetostrictive transmission medium 221a. The coil 223 is used to generate magnetostrictive vibration waves at each winding portion of the coil 221b, and one end of the coil 223 is connected to the identification circuit 300.
The narrow end is connected to the pulse current generator inside, and its narrow end is grounded. The reference position designating magnet 224 is connected to the magnetostrictive transmission medium 221a, 2
This is for applying a bias magnetic field parallel to the longitudinal direction to the wound portions of the coils 223a and 223b of 21b. The reason for applying a bias magnetic field in this manner is to enable generation of a large magnetostrictive vibration wave with a small current, and to specify the generation position of this magnetostrictive vibration wave. That is, the electromechanical coupling coefficient of the magnetostrictive transmission media 221a, 221b<m mechanical energy to electrical co]energy, or electrical energy 1! -coefficient indicating the conversion efficiency from - to mechanical 1 energy)
For example, as shown in FIG.
By applying the voltage to the wound portions 23a and 223b, magnetostrictive imaging waves can be generated efficiently. The second coils 225a and 225b are the magnetostrictive transmission medium 221
Reinforcement material 222a over a wide range of a, 221b,
222b and 1:, respectively. Each coil 225a, 225b is connected to each magnetostrictive transmission medium 221a, 221
The windings are wound in the same direction (left-handed in this embodiment) between b and h, and are connected in series so that the polarities of the connections are opposite to each other, so that external induction and noise cancel each other out and are weakened. Coil 225a. The winding pitch of 225b is preferably large in order to increase the induced electromotive force. For example, in this example, the winding pitch is 7 turns/turn on average.
cm. In addition, in order to compensate for the decrease in the induced voltage due to the attenuation of the magnetostrictive oscillation 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 coil 225
a and 225b are for detecting the M conduction voltage due to magnetostrictive vibration waves propagating through the magnetostrictive transmission media 221a and 221b, one end is connected to the pulse detector in the identification circuit 300, and the other end is grounded. , the wound area becomes an identification (position detection) area. The aforementioned identification mark detection unit 220 is located on one side 2 of the housing 201.
03 and fixed with adhesive or the like as necessary. More precisely, the menu sheet 100 is the input board 20.
The identification mark detection unit 220 is installed so that when placed at 0F, the reference position 109 and the generation position of the magnetostrictive vibration wave, that is, the position of the 1:1 tile 223, match. are fixed so as to face the ends of the magnetostrictive transmission media 221a and 221b, but the magnetostrictive transmission medium 221a
, 221b above. -C may also be arranged in parallel below or on the side. The identification circuit 300 includes a control circuit 301 and an output buffer 1302.
, pulse current generator 303 , counter 304 , clock generator 305 , pulse detector 306 , etc. Input buffer 730
It consists of 1. Below, the operation of this device will be described in detail along with a description of each circuit. Now, in the menu sheet 100, the identification magnet 108
is the reference position 1ffi 109 as a reference for the identification mark section 1.
The frame attached to the fourth position (distance from the reference position 109 is g) of the frame 11 degrees (not shown with broken lines in the figure) provided at 05 is taken. When such a menu sheet 1oo is placed on the input board 200F, the first-J file 22 of the identification mark detection section 220
A magnetostrictive transmission medium 22 with a distance tltfl from the center of the coil surface of No. 3
1a and 221b, and magnetism is applied to the magnetostrictive transmission medium 22 to the extent that the electromechanical coupling coefficient becomes large.
1a and 221b. The control circuit 301 inputs menu sheets 1 to 100 to the input board 20.
It receives a signal from a microswitch (not shown) that is turned on when placed on the 0J2, or starts detecting the identification mark according to a predetermined detection cycle. First, the control circuit 301 operates the pulse current generator 303 via the output buffer 7302 and also operates the counter 3.
Reset 04. The counter 304 starts a clock pulse (pulse repetition frequency is, for example, 100 MHz) from the clock generator 305. When the pulse current generator 303 operates and a pulse current is applied to the first coil 223, a WR magnetic field fluctuation occurs in the first coil 223, which causes the magnetostrictive transmission medium 221

[Propagate. Then, the magnetostrictive transmission medium 221 in which the -C1 magnetostrictive vibration wave exists during this propagation.
Conversion from mechanical energy to magnetic energy is performed at the locations a and 221b depending on the magnitude of the electromechanical coupling coefficient at that location, and therefore the second coils 225a and 221b
5bk: ltl electromotive force is generated q, tl. FIG. 7 shows an example of the temporal change in the induced electromotive force generated by the second coils 225a and 225b, with t=O representing the time when a pulse current is applied to the first coil 223, and 1c. As shown in the figure, the amplitude of the induced electromotive force is immediately after time 1=0 at time t. It increases by r when t1 to t2 seconds have passed since then, and decreases at other times. Time t=Q
The reason why the amplitude of the induced electromotive force becomes large immediately after is due to the electromagnetic induction effect between the first coil 223 and the second coils 225a, 225t), and from time 1 = 11 to t2 - (
One cycle of induced electromotive force (induced voltage due to magnetostrictive vibration waves)
The reason why the amplitude becomes large is that the magnetostrictive vibration waves generated in the winding portion of the first coil 223 are transmitted to the magnetostrictive transmission medium 221a. 221b and reaches the vicinity of the identification magnet 108, where the electromechanical coupling coefficient becomes large. When the position of the magnet 108 is on another frame 110,
That is, when the magnetostrictive transmission media 221a and 221b are at different positions along the longitudinal direction, the induced voltage due to the magnetostrictive vibration waves also moves on the υ time axis accordingly. Therefore, time 10
Magnet 1 by measuring the time from t1 to t2
It is possible to highlight the position 08, that is, the distance 5ifJ. The propagation time of the IC that determines the position is, for example, the 7th IC.
As shown in the figure, the time point 11 when the amplitude of the induced voltage becomes smaller than the threshold value -El, and the time point 14 when it becomes larger than the threshold value E1 may be used. You may also use The induced electromotive force generated in the second coils 225a and 225b is input to the pulse detector 306. The pulse detector 306 is composed of an amplifier, a comparator, etc., and sets its output to a high level while the induced electromotive force is greater than, for example, the aforementioned threshold value E1, that is, when the positive polarity portion of the induced voltage is detected. When the control circuit 301 reads this high level signal via the input saw buffer 307, it outputs a stop signal to the force 1 counter 304 via the output buffer 302 to stop counting. At this time, counter 3
04, 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 appearing in the magnetostrictive vibration wave appears in the second coils 225a and 225b is obtained. Further, this value corresponds to the distance @3 from the 11th coil 223 to the magnet 108 because the magnetostrictive vibration wave advances at a speed of s,0oom per second. In this way, the counter 304 is converted into a digital value.
The obtained value 1=distance 1lIi41, that is, the position of the m stone 108, is read into the control circuit 301 via the input buffer 307, and further sent to the processing device 400. Various types of menu sheets 10 are stored in advance in the processing device 400.
The contents of the menu sheet 103 of 0 and the corresponding position r of the magnet 108 in the identification mark section 105 are stored, and by comparing and collating the position data from the identification circuit 300, the information is placed on the input board 200. It is possible to accurately recognize the type of menu sheet 1-100. Therefore, after that, the menu can be entered manually by simply touching the input menu 106 with the input pen 500. Also, after this, the menu sheet 100 was changed one after another, and C also changed the menu sheet 100 one after another.
Identification of the menu sheet 100 as described above is performed, and correct menu input is possible. In the above embodiment, the first coil 223 was used for generating magnetostrictive vibration waves, and the second coils 225a and 225b were used for detecting magnetostrictive vibration waves, but they can also be used in the opposite way. A magnetostrictive vibration wave is generated directly below the magnet 108, and the first
An induced voltage will be detected in the coil 223. Furthermore, in the above embodiment, when a plurality of magnets 108 are arranged in parallel on the frame 110, induced voltages with large amplitudes are obtained on the time axis corresponding to the position of each magnet 108, so this must be converted into a pulse train. For example, identification can be made by the number or combination of magnets 108. Note that in the present invention, magnetic field (magnetic flux) fluctuations are expressed as voltage. An element or device that converts a change in current, etc., or converts a change in voltage, current, etc. into a magnetic field fluctuation is called an electromagnetic converter. Although a coil is used as the electromagnetic transducer in the embodiment, the present invention is not limited to this. (Effects of the Invention) As explained above, according to the present invention, there is provided a menu sheet with an identification mark based on the position or number of magnets placed on one side of the sheet body, or a combination thereof, and a menu sheet based on the magnets. Since it is equipped with an input board that has an identification mark detection section that detects the M-specific voltage and a menu manual section, and an identification circuit that detects the position of the magnet from the induced voltage, the menu sheet I~ can be input to the input board. The type of menu sheet can be identified by the number placed on top, and therefore, many types of menu sheets 1 to 1 can be used by replacing them one after another without having to enter an identification code or the like using other input means as in the past. can,
This has advantages such as being able to provide a menu sheet input device with extremely good operability.
