15 As a prior art of this type, there is Japanese Patent Publication No. 53-34855 filed by the same applicant.

As shown in FIG. 2, electrical conductor wires 21b and 21c are formed on the front and back sides of an electrically insulating sheet-like material 21a with a phase shift of 90 degrees in electrical angle, that is, a voltage waveform 20 of Sln-coS. X-axis and Y-axis electric conductor branch lines 22b1, 22b2, .
. . , 2251, 22c2, . The base 2330 for the Y-axis is formed such that the electric conductor wires 23b and 23c are shifted in phase by 90 degrees in electrical angle, that is, the voltage waveform is Sln-cos perpendicular to the base 21 for the X-axis. In addition, the three bases 21 to 23 have a sandwich structure. To detect coordinates using this coordinate detection device A, an oscillation coil is placed on the coordinate detection device A,
It is possible to obtain the position of this oscillation coil as X and Y coordinates. That is, the coordinate area in the X and Y directions obtained by the electric conductor lines 22b and 22c of the coordinate area detection base 22 in FIG. The coordinate values of the oscillation coil on the coordinate detection device can be detected using the coordinate values within each coordinate area in the X and Y directions obtained by the conductor wires 23b and 23c.

However, this method only allows you to know the location of any point, that is, the coordinates.

, B and FIG. 5 have the same structure except that the symbol marks are different. F is a display device corresponding to the display window provided in the drafting tools B and C (this display device F is a display device that corresponds to the display window provided in the drafting tools B and C).
It is not necessary to have it when it is provided in C, and it is necessary when it is not provided in drafting tools B, and C.

) and displayed on the display window, the same information is displayed. G is a menu sheet placed on the coordinate detection device A, and is used to specify various states such as dotted lines and thick lines when creating drafts and diagrams. H is a keypad, which replaces the menu sheet G mentioned above. 1 is a data processing device interface to which the command switches of the scale B and template C described above are connected, as well as a display device F) and a keyboard H; j is a data processing device, and from the data processing device interface 1, The data is edited based on the output of the controller, and is output to a magnetic tape, paper tape, magnetic disk, typewriter, etc., and is composed of a coordinate detection circuit 22, a calculation circuit 23, a data editing circuit 24, and a storage circuit 25.

Next, the operation will be explained based on the above configuration. The coils 2 and 3 provided on the free scale B are alternately excited to obtain respective coordinate values on the coordinate detection device A. Similarly for template C, coil 6, T
By alternately exciting the coordinates on the coordinate detection device A, the coordinate values are determined. Free scale B, point P on template C.

The positional relationship of the center point of each symbol on template C with respect to coils 2, 3 or 6, T is known in advance, and when the coordinate values of coils 2, 3 or coil 6, T are obtained, PO and The coordinates of the center point of each symbol are calculated as follows. Now consider a coordinate system in which the center of the coil 2 is the origin (0, 0) and the center of the coil 3 is on the X axis (Xl, O). P in this coordinate system. The coordinates of are known and can be expressed as (X2, y2), and the memory circuit 25
” is remembered. When free scale B is placed at any position on coordinate detection device A, the coordinates of the center of coil 2 are (X, Y), and the coordinates of the center of coil 3 are (X1 =
Assuming that X'1+X, Yl=yl'+Y) is obtained,
The coordinates (X2, Y2) on PO(!7)A at this time can be determined by the calculation circuit 23 as follows.

Even in the case of template C, if we consider coils 6 and 7 to correspond to coils 2 and 3 of Freescale B, P. Since the position of O and the center point of each symbol with respect to the coils 6 and 7 is known, P
O, the coordinate values of the center point of each symbol, etc. can be easily obtained. Typical usage of Freescale B is as shown below: initial value setting, point cloud data input, line segment data input, parallel line input, data elimination method, and when tracing curves. I will explain six points. First, when designing or modifying a paper or drawing by placing it on the coordinate detection device A.

The positional information of design information and correction information (for example, line segments and symbols) to be entered or deleted is given as coordinate values fixed to the coordinate detection device A, but is given as positional information with respect to the coordinate axes set on paper or drawings. is much more convenient to handle on a computer.

Therefore, when a piece of paper or a drawing is placed on the coordinate detection device A, an operation called initial value setting is performed to find the coordinate axes of the paper or drawing. (1) To explain the initial value setting, first, when you press the initial value setting switch (for example, 411) among the command switches 411 to 41n, the upper end surface of scale B (or the line connecting the center lines of coils 2 and 3) becomes one coordinate axis (generally the X axis), and POt at this position is the origin (0,0
) is stored in the calculation circuit 23 as .

In addition, when changing the origin and coordinate axes on the way, the calculation circuit 23 and data editing circuit 2
By making corrections in step 4, it is possible to change the data to a new coordinate system. Once the initial values are set, the confirmation lamp (
For example, 421) is lit. Therefore, as will be described in detail later, when the free scale B is moved, the amount of movement and the movement angle at that time are calculated in relation to the initial values and displayed on the display windows 43, 44 or the display device F. To specify the type of line used in the above, e.g. solid line, dotted line, etc., place the PO on the relevant part of the menu sheet and press the command switch (for example, 4
, 2) or input the data into the data editing circuit using the keypad H. Also, when inputting the following data, confirm that the data input confirmation lamp (for example, 422) is lit. 1) Next, to explain point cloud data input,
After setting the initial values, select the coordinates Pi of the point group Pi whose coordinates you want to know.
To find the point, place the point PO on the scale at the point Pi and press the point coordinate input switch (for example, switch 413).

From the relationship with the outputs of the coils 2 and 3 of the coordinate detection circuit 22, the calculation circuit 23 determines the coordinates Pit of the point group Pi in the coordinate system determined in the initial value setting, and displays it on the display windows 45 and 46 and the display device F. and the data editing circuit 24
and recorded on a recording device. Contrary to the above, if you want to find a desired angle, distance, or coordinate point from a certain point Pl on the coordinate detection device A, move the free scale B while looking at the display device F or 4 and find the desired angle. This can be determined by pressing the command switch 413 at the distance or coordinate point and plotting the position of the free scale BOPO. , ) Next, to explain the data input of a line segment, it is similar to the data input of the above point group, but the point P on the free scale B is added to the start and end points of the line segment.

, and press the line segment data input switch (for example, switch 414) at each point. Also, if you want to draw a line segment at a desired angle, distance, or coordinate using a certain point as the starting point, it is the same as inputting point cloud data, and you can use Freescale BO as the starting point.
Apply PO, press switch Cl4, move free scale B while looking at display device F or 4, and press switch Cl4 again when the line segment of the desired angle, distance, and coordinates is obtained (end point) to display the desired line. This allows you to actually draw a line on the drawing to indicate the starting point and ending point. (5) Next, to explain the case of drawing parallel lines, if a reference line is drawn (or an angle is given), apply free scale B to the reference line and display on display device F or If you check the angle in 4 and then draw a line at the same angle, you will get parallel lines.

(V) Next, to explain how to erase data, press the erase switch (for example, switches 4 and 5), confirm that the erase confirmation lamp, for example 423, lights up, and then move the free scale BOPO to the point group or line segment starting point. , hit the end point and press switch 413 for a group of points, or press switch 414 for a line segment.

Then, once all the items have been erased, switch 415 again.
Press (at this time, the above confirmation lamp 423 will turn off),
If necessary, the points and line segments may be erased on the drawing using an eraser or the like. (Auto) Next, to explain continuous input when tracing a curve, etc., press the continuous input switch (for example 416), confirm that the confirmation lamp for example A24 lights up, and then move Freescale B (1) PO to the curve. , the value of POt is calculated and output at regular intervals (for example, 10 to 100 points/second) until the switch 416 is pressed again. To erase, press the switch 415 and repeat the same operation, and if necessary, erase on the drawing with an eraser or the like. As mentioned above, it is possible to input and modify various information using Freescale B, but for symbols often used in electrical circuits, etc., it is often convenient to use Template C, which has these symbol marks prepared.

To explain the embodiment of template C, to explain the embodiment of the above-mentioned free scale B, this template C is also provided with coils 6 and T as in the case of the above-mentioned free scale B. , the positions of a certain point PO of the template C and the center point of each symbol with respect to the coils 6 and T are known;
As in the case of free scale B, even if template C is placed at an arbitrary position on coordinate detection device A, the coordinates of PO and the center point of each symbol can be directly determined.

Therefore, the same operations as those for Freescale B described above can be performed with Template C, but since these operations are the same, the explanation will be omitted. Deletion of connections, symbols, and inter-symbol connection data will be explained.

(l) Each symbol 81 to 8n of template C is provided with a switch 9, to 9n made of a micro switch or a conductive rubber whose contact point is closed when a pencil or the like is moved along the symbol.

Further, the position of each symbol 81 to 8n with respect to the coils 6 and T in template A is fixed, and information on the center position of each symbol 8 and 8n is stored in the calculation circuit 23 together with the direction of the symbol. Therefore, when the template C is placed on the coordinate detection device A, the direction of the selected symbol and the coordinates of the center of the symbol are determined in the calculation circuit 23 and sent to the data editing circuit 24. In other words, when inputting a symbol, if you draw along the symbol (e.g. 81) with a pencil or the like, the switch (e.g. 91) is closed, so the above-mentioned calculation circuit 23
The coordinates, direction, name, etc. of the center position of the symbol are displayed on the display devices F, 1O based on the output from the symbol. For example, for items that use the same symbol mark but have different names and values, such as ICs, LSIs, resistors, and capacitors in electrical circuits, this information can be displayed on the attached switch group, keyboard, or menu. can be entered.

01) Next, to explain the connection between symbols, place the point PO of the template C on or near the symbol that should be the starting point or end point of the connection on the drawing that has already been drawn, and press a command switch (for example, switch 1013).
By pressing , it is registered as the start point or end point of the connection data, and the data editing circuit 24 edits it as connection data.

When the switches 10, 3 are pressed at each point, the name of the symbol to be the starting point or ending point of the connection and, if the symbol has input/output distinction, are displayed on the display device F or 10. () Next, to explain about erasing symbols and erasing connection data between symbols, when erasing a symbol that has already been registered, place the PO of template C on the center of the symbol and display it on the display device. Confirm and press the symbol deletion switch (for example, switch 10, .).

While this button is pressed, the erase confirmation lamp (e.g. confirmation lamp 1)
023) lights up. At this time, the connection data with this symbol as the starting point or ending point are also erased at the same time. If necessary, you can erase the lines on the drawing with an eraser or the like. Furthermore, since the erasure of connection data between symbols is the same as the erasure of line segment data, the explanation will be omitted. As described above, in the present invention, since at least two detection coils are provided on the free scale and template, the coordinates and distances of point groups and lines can be easily determined and recorded by placing them on a coordinate detection device and operating them. Moreover, if symbols are provided, their shapes, orientations, center coordinates, inter-symbol connection data, etc. can also be recorded.
