Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digitizer having an editing function of recognizing a coordinate position and editing contents of editing information added on a digitizer and transferring the same to a copying machine.

[0002]

2. Description of the Related Art Recently, it has been proposed to use a digitizer as a means for editing a copy image, and a digitizer of this type electrically connected to a copying machine has already been commercialized.

These digitizers are provided with a position information input section for inputting position coordinates of a document set on the tablet surface and a function information input section for inputting specific edit contents, and the latter function information. The input section includes various function keys such as a key for designating a range of an edit target in a document, a key for moving the edit target to another position, and a key for designating a moving direction and a distance thereof. Are arranged.

In order to carry out editing work using such a digitizer, first, a manuscript is set on the tablet position information input section, and necessary position information and function information are input using a dedicated information input pen or the like. After that, the original is transferred to the copying machine and the operation of the copying machine is started. As a result, the copying machine can execute the copying / editing operation based on the specified editing contents and print out the editing result on a predetermined paper.

[0005]

However, in the digitizer configured as described above, since the position information input operation section and the function information input operation section are located apart from each other,
There is a problem in that the input operation is not efficient because there is the trouble of having to reciprocate between the input sections many times to perform one editing operation. Further, since the specified contents such as the position of the area input to the digitizer during the editing work cannot be confirmed, there is a problem that a mistake is noticed only after copying is completed by a copying machine after the editing work.

The present invention has been made in view of such a situation, and enables a simple and reliable input operation of various editing information, and has an editing function capable of confirming the position of an area input during editing work. To provide a digitizer.

[0007]

In order to solve such a problem, a digitizer having an editing function of the present invention sets an original on a copying machine to make a copy, sets a copied sheet on a digitizer, and sets a pencil. It has a function of writing editing information on a sheet copied with a writing instrument such as a ballpoint pen, recognizing the position and content of the editing information added with the writing instrument, and transferring the recognition result to a copying machine. ..

[0008]

In the digitizer having the editing function having the above-mentioned structure, the copied paper is set on the tablet, and when the editing information is input to the copy image using the writing instrument, it is recognized, and the recognition result is transferred to the copying machine. Since the data is transferred, the copying machine makes a copy in consideration of the transferred content. As a result, all editing information can be input by the position information input operation unit.

[0009]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 shows a copy editing system using a digitizer having an editing function to which the present invention is applied.
In this system, the code machine 1 and the digitizer 3 are code 9
It is configured by connecting by. The copying machine 1 in the illustrated example is a laser copy, which performs copy editing processing and prints out the editing result.

The digitizer 3 is a writing instrument 5 for inputting by designating an arbitrary point on the tablet 4 in order to edit an image to be copied on a copied sheet, and a plurality of function keys formed below the tablet 4. By providing 6, the information required for editing can be input.

A function key 6 formed below the tablet 4 is for inputting function information.
As a concrete key name of this function key 6,
Although not shown, there are an end key for ending the input operation, a clear key for clearing the input information, a numeric keypad for inputting numerical values, and the like. In the actual editing operation, after selecting and pressing the corresponding key from these function keys 6, the position information of the writing instrument and the functional information such as the area confirmation are input in a predetermined order based on the specified editing menu contents. By doing so, the specific edit content of the copied paper 2 is specified.

FIG. 2 is a block diagram showing a circuit configuration of the digitizer 3. The coordinate conversion circuit 31 digitally converts the coordinate signal from the tablet 4 including the depression signal of the function key 6 and sends it to the control unit 32. Control unit 32 is CP
The microcomputer 33 is composed of a microcomputer including U33, ROM 34, RAM 35, etc., and the CPU 33 executes a program stored in the ROM 34 to process the input data relating to each editing and transfer it to the copying machine 1 side.

In particular, the control unit 32 processes the position information and the function information input in a predetermined order using the writing instrument 5 based on the editing menu contents designated by pressing the function key 6, and the copied sheet 2 A predetermined editing process regarding is performed.

FIG. 3 is a block diagram showing a main part of an internal circuit of the copying machine 1. The copying machine 1 includes a CPU 11 and an R
It is composed of a microcomputer including an OM 12, a RAM 13 and the like, and the CPU 11 executes a program stored in the ROM 12 to realize a function as a copying machine.

The image scanner 14 is a laser scanner, which scans the set original 2 and converts the contents of the original into a binary signal corresponding to the density of the pixels to generate image data. The frame memory 15 stores the generated image data and the edited image data. ..

The laser printer 16 includes a frame memory 1
The edited image data stored in 5 is reproduced on a photosensitive drum (not shown) by using a laser beam, and then printed on a predetermined paper and output.

FIG. 4 is a flow chart showing an example of the editing operation in the above-mentioned embodiment. The editing executed here is to erase the upper left image "A" of the copied sheet 2 (a) as shown in FIG. The operation procedure will be described below with reference to FIGS. 4 and 5 according to the flowchart.

First, in FIG. 4, as a preparatory step, a document is set on the copying machine 1, the document is copied, and the copied sheet is set on the digitizer 3 (step 40).
0). Next, the edit start key of the function keys 6 is pressed to specify the edit menu. (Step 4
01).

Thereafter, as shown in FIG. 5A, the periphery of the image "A" to be erased of the copied document 2 set in the digitizer 3 is surrounded by a continuous line 21 by the writing instrument 5 (step 402). Then, in the area surrounded by the continuous line 21, the writing tool 5 draws a "x" mark indicating erasure (step 403). When the above operation is completed, the edit end key of the function keys 6 is pressed (step 404), and mode recognition is started (step 405).

The function information and the position information recognized thereby are transferred to the copying machine 1 (step 406), and the copying machine 1 performs the copying processing in consideration of the processing according to the information (step 407). As a result, the "x" mark drawn in the continuous line 21 is recognized as erasing the graphic in the continuous line 21, and is surrounded by the continuous line 21 from the information copied by the copying machine 1. Since copying is performed with the information in the part deleted, copying is performed with the image [A] erased as shown in FIG. 5B.

This function recognition is performed by recognizing that the "x" mark drawn in the continuous line 21 is to erase the image in the continuous line, and this processing is performed. (Kenji Omori "Real-time Handwritten Kanji Recognition by Fuzzy Reasoning" IEICE Transactions D-II VOL.J7
2-D-II No. 3 pp. 369-379 19
This can be done by applying the method described in (March 1989).

In this method, the handwritten input information is Fourier-transformed to grasp the characteristics of the input pattern, and the center of gravity of the input image, the distance between the start point and the end point, and the degree of bending are extracted. Generally, even if the same person, the image to be input is
It is not possible to draw things with exactly the same shape, and the drawn things will differ slightly depending on the situation at that time. Therefore, fuzzy inference is performed and recognition is performed in anticipation of the allowable width. Then, the mode is determined by comparing the recognition result with a certain registered pattern.

Therefore, since the edit content input by handwriting is recognized to determine the edit mode and the position of the edit content can be recognized when the continuous line 21 is drawn, these two pieces of information are transferred to the copying machine 1. If so, the copying machine 1 adds the transferred information to the content read from the original, and in this example, the image "A" is erased to perform copying, so that as shown in FIG. The image [A] is erased and copied.

The original 2 thus copied is placed on the digitizer 3, and the editing range and the editing contents are written on the original 2 by the writing instrument 5. Therefore, the editing range is known at that time,
You will never find out the failure after copying. Further, since the information on the digitizer 3 is transferred to the copying machine 1 and copying is performed by taking the transferred information into consideration, it is sufficient to input the editing information only by the position information input operation section, and one editing operation can be performed. It is not necessary to repeatedly perform the reciprocating motion between the input units to perform the operation.

[0025]

As described above, the digitizer having the editing function according to the present invention recognizes the editing information input by the writing instrument on the copied sheet placed on the digitizer and transfers the information to the copying machine. Then, since the editing is performed in consideration of it, there is an effect that the editing can be performed easily and surely.
