Description

[Detailed Description of the Invention] The present invention relates to a digitizer for reading and inputting original documents.

When a digitizer reads figures drawn on a document and inputs the information into a computer connected to the digitizer, the cursor, which can be freely moved on the document placement plate of the digitizer, is usually moved over the document. It relies on a series of operations such as locating the document set on the placement plate at the reading point and pressing the input key.

However, if the content of the document is rough, it is impossible to read the exact coordinates intended by the document using only the operations described above.
coordinate values) from the specified distance, angle, etc.,
I need to add it.

Conventionally, for this type of retouching work, accurate numbers were calculated using a slide rule, calculator, ruler, etc. prepared separately from the digitizer, and then written in the necessary places on the manuscript. Input was performed using a keyboard connected to a digitizer.

However, such supplementary work is extremely troublesome, and there is also a risk that it may lead to calculation errors, transcription errors, input errors, etc.

In particular, when a digitizer is used in an automatic drafting system for printing, the original figures of the draft are often drawn roughly, and the number of numerical dimensions specified is minimal.On the other hand, the dimensions of the draft as a product Since accuracy is required, there is a lot of retouching work by the draft creator, and there is a strong desire to automate this kind of draft creation work. It is inadequate to simply upgrade the software that supports this.
It is considered important to take advantage of the worker's cognitive ability and input data in accordance with the original intent at the time of digitizing.

The present invention was developed in view of the current situation, and is configured so that the operator can use the cursor to calculate dimension corrections when digitizing, thereby eliminating the above-mentioned retouching work and making it easier to understand the original intent. It is an object of the present invention to provide a digitizer that allows an operator to understand and interactively perform dimension correction, thereby greatly improving work efficiency or shortening work time.

The present invention will be explained in detail below based on the embodiments shown in the drawings.

FIG. 1 is an explanatory diagram showing the external appearance of the digitizer of the present invention, FIG. 2 is an enlarged explanatory diagram of a position coordinate detection instruction cursor, and FIG. 3 is a block diagram of the main parts of the digitizer of the present invention. FIG. 4 is an explanatory diagram of a draft manuscript for printing.

In FIG. 1, 1 is a document reading device according to the present invention, 2 is a document placement plate in which lines of magnetic force are regularly arranged in the X and Y directions, and 3 is a keyboard. , 4 is a display device for displaying position coordinates (X coordinate, Y coordinate), and 5 is a position coordinate detection instruction cursor connected to the central processing unit of the digitizer 1.

The position coordinate detection instruction cursor 5 has a position coordinate detection section 11 as shown in an enlarged view in FIG.
By magnetically coupling with the object, its position coordinates can be read.

Further, 12 is a group of keys including four arithmetic operation keys, function keys, instruction keys, etc., 13 is a calculated value display device that displays numerical values calculated by a numerical calculation processing device, which will be described later;
4 is a position coordinate display device that displays the X coordinate and Y coordinate separately.

Note that the instruction keys of the key group 12 include an import key for importing a calculated value as an X or Y coordinate value, and a calculated value input key 1 for reading the coordinate value into the digitizer body as a document position coordinate value. It consists of a call key etc. for displaying the coordinate values etc. displayed on the display device 4 of the position coordinate detection instruction cursor on the position coordinate display device 14 of the position coordinate detection instruction cursor.

Further, inside this position coordinate detection instruction cursor 5, there is a numerical arithmetic processing device as shown in FIG. A device 15 is provided, and these arithmetic device 16 and storage device 17 are connected to the control device 15 along with the above-mentioned key group 12 and display devices 13 and 14.
Connect to.

This control device 15 is connected to a central processing unit 21 of the digitizer main body.

Thereby, by operating the four arithmetic operation keys or function keys on the position coordinate detection instruction cursor 5, calculations are performed in the calculation device 16, and the calculation process and calculation results are displayed on the calculation value display device 13.

If you want to import this calculated value as an X coordinate value, just press the X coordinate value import key in key group 12, and if you want to import this calculated value as a Y coordinate value, press the Y coordinate value import key in the same way to display the position coordinates. Displayed on the device 14 and also stored on the storage device 17
is memorized.

Further, when inputting the coordinate values calculated on the position coordinate detection instruction cursor 5 into the central processing unit 21 of the digitizer main body as graphic data of the document, the calculation individual key in the key group 12 may be pressed.

When reading the positional coordinates of figures, etc. drawn on a document with such a configuration, the document is placed on the document placement plate 2, and the positional coordinate detection instruction cursor 5 is moved as in the conventional method. Position coordinate detection unit 1 at the point where the position coordinates should be read
After matching the centers of 1 (the coordinate values are displayed on the display device 4 or the position coordinate display device 14) and pressing the input key, the coordinate values can be imported as graphic data.

On the other hand, if the document is rough and it is impossible to directly read the coordinate values as described above, use the four arithmetic operation keys provided on the position coordinate detection instruction cursor 5 to obtain the coordinate values based on distance or angle. and is calculated by the arithmetic unit 16.

This calculated value and the process of calculation are displayed on the calculated value display device 13, and if the calculated value is to be the coordinate value of the X or Y coordinate value, it can be imported as the coordinate value of the X or Y coordinate by pressing the import key. and is displayed on the position coordinate display device 14.

When inputting the coordinate values calculated and determined in this way into the digitizer main body as the graphic data of the original, by pressing the calculation individual key, the coordinate values are directly imported as data from the control device 15 to the central processing unit 21 of the digitizer. .

For example, when reading the printing plate original 31 as shown in FIG. 4, the original intention is E F / GH in the rectangle ABCD and the straight lines EF and GH, and the parentheses EF and GH are inscribed in the rectangle ABCD. be.

Here, since the original figure is roughly drawn, it is impossible to digitize points E, F, G, and H as accurate values using a conventional digitizer, and the coordinate values that are inaccurately digitized cannot be used. Accurate coordinate values for points EF, G, and H had to be obtained by performing graphic processing calculations using a graphic processing computer.

According to the present invention, the position coordinate detection instruction cursor 5 is placed on point B, and the key group 12 is operated as follows.

Use the call key to get (BX, BY), Bx+L1
Perform the calculation and use the import key (BX t, l,
By) is input into the computer 21 as the coordinate value of G (Gx, GY) using the personal computer key.

Also, regarding Hx-Cx-, using each key in the same way, Hy = (cX-Gx
)tan(9-1-Gy) and the coordinates of H are read using the capture key.

E and F can also be read in the same way.

Therefore, since the human figure recognition ability, which is much more advanced than that of a computer, can be fully utilized at the time of the reading operation, there is no need to spend a long time on the figure processing operation using a computer after the reading operation.

Note that the above is an explanation of one embodiment,
The present invention is not limited to this embodiment in any way.

That is, the key group 12 surrounded by a chain line in FIG. 3, the display device 1
3, 14, control device 15, arithmetic device 16, storage device 17
are provided on and inside the position coordinate detection instruction cursor 5, but the numerical calculation processing device, that is, the control device 15, the calculation device 16, and the storage device 17 are provided on the position coordinate detection instruction cursor 5.
Alternatively, the position coordinate detection instruction cursor 5 may be provided with only the key group 12 and the display devices 13 and 14, which are surrounded by a dashed line.

Further, in order to detect the position of the position coordinate detection instruction cursor 5, magnetic coupling between the position coordinate detection unit 11 of the cursor 5 and the original plate 2 is used, but the present invention is not limited to this. .

The present invention is as described above, and as with conventional digitizers, the coordinates of that point can be digitized by positioning the position coordinate detection instruction cursor at the coordinate reading point of the document and pressing the enter key. Of course, if the manuscript is rough and input operations are not possible as described above, in order to determine accurate coordinate values, angles, lengths, etc. are used to calculate By operating the calculation keys provided on the position coordinate detection instruction cursor, which is the easiest to handle, calculations can be performed using a calculation unit provided separately from the digitizer's central processing unit (computer), without the need for a calculator or solopan. The calculated values can be directly input into the digitizer's central processing unit as coordinate value data, which not only eliminates the complexity of the conventional method, but also minimizes the occurrence of input errors, calculation errors, etc. This can be kept to a minimum.

In addition, since the cursor has a coordinate display device separate from the coordinate display device on the digitizer body, the calculated numerical value and the coordinate value where the cursor is located are displayed at hand, making it very easy to see. It is also very convenient for cursor key operations.

In this way, when using a digitizer or a block production system that incorporates a digitizer, the rewriting work, which is centered on the four arithmetic operations, which was previously considered to be a very troublesome task, can be replaced with a large scale work such as a digitizer or a block production system that incorporates a digitizer. There is no need to use a computer, and by incorporating it as compact hardware, it is possible to improve work efficiency, save space, and improve accuracy.
