Description

[Detailed description of the invention]

[Technical Field] The present invention relates to a coordinate display device that selectively displays positional data instructed to a position detecting tablet by operating a magnetic material or a keyboard on a display. (Prior Art and Problems) Conventionally, the tablet 1 for writing handwritten characters and figures, and the display for displaying the handwriting and recognition results, were provided by input/output devices for characters, etc., which were constructed independently and separately. However, to confirm that the characters and shapes entered in tab knot-1 are correctly recognized and typed,
It is necessary to view the board surface of the tablet and the display surface at the same angle, which obstructs the input operation of handwritten text, resulting in poor operability. In addition, when editing characters such as 91 correction or insertion, you can move the cursor to specify the position of the character to be corrected or inserted, so check the current position of the cursor and the position of the target character in the document. The user had to move the cursor while doing so, making it difficult to use. On the other hand, on the other hand, if there is a coordinate human output device that integrates a tablet and a display, for example,
It was proposed in Publication No. 7, etc., that it is possible to directly specify any position in a displayed document on a tablet (or with a stylus pen connected to a character recognition circuit), and perform editing work.
Input/output work has become easier. In other words, from the input stage, the scribe writes sentences arbitrarily according to the input appearance that appears on tablef 1 to earth, or C1 as if he were creating sentence m while doing leiara (・) on the surface of the output paper. It is possible to improve the operability of the
Letter tI in letter I letter 1-1, letter tI in figure entry area
? When writing on i!, the -1- card that connects the character recognition circuit and the stylus becomes a part of the tablet, and if the stylus does not touch or come close to the tablet when writing on i! ′!
There was a practical problem in that it was not possible to specify characters and positions in Itorimaro. In addition, the coordinate input/output device described above allows coordinate input and editing work only with a stylus pen, and the structure does not allow direct input of clear characters and symbols using a keyboard device. Practical use of slowing down editing and editing of complex characters etc.
I had this problem. [Purpose of the Invention] The present invention solves and overcomes the problems of the prior art, and uses a cordless magnetic material to display characters and symbols as position data specified on the tablet on a display integrated with the tablet. In addition, J for keyboard devices:
An object of the present invention is to provide a coordinate input/output device that can arbitrarily display selected characters and symbols at positions designated by a position designation device. [Principle of the invention] When a magnetostrictive vibration wave propagates in a magnetostrictive transmission medium, a part of the mechanical vibration energy is converted into magnetic energy in the region where the magnetostriction vibration wave exists, and a local magnetic field fluctuation occurs. The magnitude of this magnetic field fluctuation increases as the coefficient (hereinafter referred to as electromechanical coupling coefficient) increases, depending on the conversion efficiency from mechanical energy to electrical energy (or from electrical energy to mechanical energy). Therefore, the electric 1 geometric coupling coefficient becomes maximum near a certain bino 1 magnetic field 1.Therefore, if t', tiL, the magnetic jt cow for position specification is applied only to a part of the magnetostrictive transmission medium with a coil wound over its entire length. A culm with a large electromechanical coupling coefficient!
111 When the Qi JJII is fixed, when the magnetostrictive vibration wave propagates through the strain transmission medium and reaches that position, it becomes large (4 & variable +h becomes /1 -, then:] A small induced electromotive force (induced voltage due to magnetostrictive oscillating waves) is generated in R1. Therefore, if the timing of the generation of this large induced electromotive force is detected, the magnetostrictive oscillating waves will be generated by the position specifying magnetic generator C. It is possible to know the time it took to reach the specified position, and from this time it is possible to detect the specified position.In addition, instantaneous magnetic field fluctuations are applied to the magnetostrictive transmission medium. The magnitude of the generated TC magnetostrictive vibration wave also increases as the electromechanical coupling coefficient becomes larger. If a magnetism is applied to the extent that the electromechanical coupling coefficient increases from If a magnetostrictive imaging wave is detected with another coil installed, the induced electromotive force (induced voltage due to the magnetostrictive vibration wave) will increase when a large magnetostrictive vibration wave reaches that coil, and by detecting this timing, It becomes possible to detect the specified position in the same way as before.Furthermore, the position signal detected in this way is input to the computer and displayed at the corresponding position on the display superimposed on tablet 1~. In addition to placing it on the same surface as the display,
Keyboard devices J3 and 4i1. 'F11 designation devices are installed, and the Iζ characters and symbols inputted from these devices are also displayed on the above display. A detailed explanation will be given. (Embodiment for shoes) Fig. 1 is an explanatory diagram C of the position detection unit in the X11 direction in one embodiment of Kizat Akira.

Alternatively, the first coil 2 in the X direction generates an instantaneous magnetic field fluctuation perpendicular to the coil surface, causing lil & strain vibration to the winding portion of each of the C magnetostrictive transmission media 18-1d. One end 2a of the coil 2 is connected to one terminal of a pulse current generator 3 which generates a pulse current sufficient to generate magnetostrictive vibration waves. , the other end 21] of each is connected to one terminal of the other. A device for applying a heavy bias magnetic field in the longitudinal direction of the strain transmission medium (1a to 1dU) is used to apply a bias magnetic field to the strain transmission medium (1a to 1dU). This is to reduce the generation of By applying a magnetic binose to the winding portion of the first coil 2, magnetostrictive vibration waves can be generated efficiently.Jj, bias magnetic material 4.a, 4.

The 221st tile 5 in the Xh direction is constructed from a to 5d. In addition, 7 is a magnetic material that constitutes the magnetic generator designated for Saga,
In this example, the rod has a diameter of 3 tam and a length of 50 mm. It is recommended to use magnets. In FIG. 1, this rod 11L7 is used to detect the position in the direction I=XIi. Further, 8 is a transmitter that transmits ultrasonic waves to notify the processor 6 of instructions to start measurement, etc., and 9 is a receiver that receives this ultrasonic signal. Mitsunobu・

The magnetism of the culm 1, which increases the electromechanical coupling coefficient, is added to -813 of the magnetostrictive transmission medium 1a below. In such a state, when a pulse current is applied from the X lj direction pulse current generator 3 to the X direction first coil 2, an instantaneous magnetic field fluctuation occurs in the X direction first coil 2.
L/, this causes magnetostrictive transmission media 18 to 1d (1) X-direction first coil 2 winding portion ('magnetostrictive vibration waves are generated. (M1 [0 speed [< about 5000 IIl/sec) (・Magnetostrictive method) The medium 1a to 1d propagates in the longitudinal direction. Then, during this propagation, at J3, (■ In the parts of the magnetostrictive transmission media 1a to 1d where strain vibration waves exist, mechanical energy is converted into magnetic energy depending on the magnitude of the electromechanical coupling coefficient at that part, and therefore the self-force in the direction of Xh Figure 3 shows an example of the temporal change in the induced electromotive force generated in the 12th coil 5 in the X direction when a pulse current is applied to the 1st coil 2 in the X direction. As shown in the diagram, the amplitude of the induced electromotive horn becomes large immediately after time t-Q and at time t-0 (Lλ seconds have elapsed from 0). and becomes smaller at other times.Time L
-The reason why the amplitude of the induced electromotive force becomes small after Oii'i is because
This is due to the electromagnetic induction effect between the Xh-direction first]1 tile 2 and the X-direction second] tile 5, and 1.1 increments 1=1. The reason why the amplitude of the induced electromotive force (induced voltage due to the 11 distorted vibration waves) of one cycle becomes large at ~t U is in the first coil 20 in the X direction.
This is because the magnetostrictive vibration waves generated in the same portion of the winding propagate through the magnetostrictive transmission medium 1a and reach a position directly below the position designating bar magnet 7, and the electromechanical coupling coefficient becomes large in that portion. When the position specifying bar magnet 7 is moved along the longitudinal direction X of the magnetostrictive transmission medium, the voltage induced by the magnetostrictive vibration wave also moves on the C time axis accordingly. Therefore, time t. In order to measure the time from l to t, the position in the X direction specified by the placement designating magnet 7, that is, the distance 1i.
