Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention communicates between a plurality of devices and does not display the document image stored in each device on the screen, and the drawing information input by handwriting is exchanged with each other via a communication line. Telefitting equipment that fits.

[0002]

2. Description of the Related Art Telewriting communications are basically
It is the exchange of images handwritten by the operator with the communication partner, but in general,
Each device is designed to exchange handwritten images while displaying the same document image on the screen.

When displaying a document image on the screen,
The necessary document images are sent to each other and stored in each device.
Then, when executing the telewriting communication, the operator selects a document and page to be displayed and displays a desired image.

The image input by handwriting by the operator is combined with the displayed document image and stored in the apparatus, and
It is sent to the other party. The operator sequentially inputs a handwritten image on each page while arbitrarily changing the page to be displayed.

[0005]

By the way, the margin for inputting an image may be insufficient by the number of pages of a prepared document.

In this case, conventionally, the displayed document is temporarily stored, for example, a new blank document is created, and the drawing information is exchanged while the document is displayed. Also,
Thus, in order to save the trouble of creating a new document during communication, a blank page is provided in the document to be displayed in advance.

However, when a new document is created during communication, the operation takes time, which causes a problem that communication efficiency is reduced. On the other hand, when blank pages are provided in advance in a document, there is a problem that the work becomes troublesome.

An object of the present invention is to solve the above problems and to provide a telewriting apparatus capable of efficiently performing telewriting communication without troublesome work.

[0009]

To this end, the present invention adds a blank page to a document when the page specified by the operator exceeds the total number of pages of the document when displaying the document image. Then, the added blank page is displayed on the screen.

[0010]

As a result, the troublesome work of preliminarily providing a blank page in the document is eliminated, and it is not necessary to create a new document during communication, so that the telewriting communication can be efficiently executed. become.

[0011]

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a telewriting device according to an embodiment of the present invention. In the figure, a main body 1 includes a scanner 2 for reading a document image.
And a printer 3 for recording and outputting an image on a recording sheet are connected.

In the main body 1, a handset 101
Is composed of a transmitter, a receiver and a signal circuit, and is used by an operator for a call. CODEC10
Reference numeral 2 is for converting a voice signal, which is an analog signal, into a digital signal when performing a telephone call with the handset 101 and vice versa.

The liquid crystal display 103 is for displaying a document image on the screen. The touch panel 104 is the liquid crystal display 1
It is integrated with 03, and the operator traces the screen with the touch pen 105 to arbitrarily input characters and figures by handwriting. Controller 10
Reference numeral 6 denotes a control for displaying an image on the liquid crystal display 103 and reading an image input from the touch panel 104. The video RAM 107 is a memory that stores image information for one screen, and the graphic controller 108 creates image information of various figures.

The image memory 109 stores image information to be transmitted and received. The interface unit 110 is for inputting image information from the scanner 2, and the interface unit 111 is for outputting image information to the printer 3.
The image information compression / reproduction unit 112 compresses the image information to be transmitted when transmitting / receiving the image information by facsimile communication, or reproduces the original image information from the received data.

The communication control unit 113 transmits / receives voice data during a call and drawing information input by handwriting, and executes known transmission control of G4 facsimile during facsimile communication. ISDN interface unit 1
Reference numeral 14 is connected to the ISDN via a network terminating device (not shown) and transmits / receives a signal to / from the ISDN. The system control unit 115 is a microcomputer including a CPU, a ROM, a RAM, etc., and monitors and controls each of the above units.

With the above configuration, the telewriting apparatus of this embodiment executes telewriting communication on a one-to-one basis.
In order to execute the telewriting communication, it is necessary to store document images to be displayed in each device in advance. Now
If one of the two communicating parties creates a document, that operator stores the document image in its own device and sends it to the communication partner device.

When storing document images, the operator
A document original is set on the scanner 2 and a document file name or the like is input by a predetermined operation to start the image reading operation. As a result, the telewriting device reads the document image and uses the document file name input as the image memory 109.
Accumulate within.

Next, when transmitting the document image, the operator inputs the destination number and the document file name by a predetermined operation and activates the transmission operation. As a result, the telewriting device transmits the document file to the other party. At this time, the file name and the like are transmitted together with the image information. The receiving side stores the document file in the image memory 109 with the file name.

Next, when executing the telewriting communication, a call is made from one side to the other side. On the calling side, as shown in FIG. 2, the operator sets the other party by a predetermined operation and activates the communication operation (process 201). When activated, the telewriting device makes a call to the other party and forms a communication link for communication with one B channel (process 203).
As a result, the operator can use the handset 101 to talk with the other party.

Next, the operator activates a telewriting communication operation (process 204). When activated, the telewriting device calls the other party again (process 20).
5) Form a communication link for telewriting on the other B channel (process 206). This makes it possible to transmit drawing information on the touch panel 104 to each other.

Next, the operator inputs the document file name to be displayed (process 207). The telewriting device reads the input document file name and sends a file open command to the other device (process 20).
8). This file open command notifies the other party of the document file name along with the command content. In addition, such 2
Information transmission between devices is performed by, for example, CCITT Recommendation T.264. 15
It is executed by a communication protocol compliant with 0.

Here, the telewriting device opens the document file corresponding to the input document file name and makes it readable (process 209). Then, the image of the first page of the document is displayed (process 210).

On the other hand, the telewriting device on the called side is
As shown in FIG. 3, in response to the incoming call (process 301), 1
A communication link for communication is formed by one B channel (process 203). The called party can talk now.

Next, in response to the second incoming call (process 30)
3) Form a communication link for telewriting on the other B channel (process 304). The callee can now send and receive drawing information. Next, the file open command is received (process 305), and the corresponding document file is opened (process 306). Then, the image of the first page is displayed similarly to the calling side (process 307).

Thereafter, the telewriting devices on the calling side and the called side execute various teleliging operations according to the operation of the operator (process 308, process 211 in FIG. 2).

In this embodiment, each operator can similarly perform various telewriting operations on the calling side and the called side by the same operation. Next, those telewriting operations will be described.

Now, as shown in FIG. 4, the operator
It is assumed that a handwritten image is input on the touch panel 104 (process 401). Then, the telewriting device reads the input image and transmits it as a drawing command to the other party (process 403). Then, the input image is combined with the page image being displayed and displayed on the screen (process 404).

Further, as shown in FIG. 5, it is assumed that the operator designates the next page by a predetermined operation (process 501).
Then, the telewriting device determines whether or not there is a next page in the displayed document (process 502). Here, if there is a next page (Y in process 502), after transmitting a display command for the next page (process 503), the image of the next page is displayed (process 504).

On the other hand, when the page being displayed is the last page and there is no next page (N in step 502), it is determined whether the page image being displayed is not a blank image (step 505). Here, if it is not a blank page (Processing 50
(N of 5)) A blank page image for one page is created and added to the document image being displayed (process 506). Then, a blank page additional display command is transmitted to the other party (process 507). Then, the blank page is displayed (process 508). In this case, the operator similarly draws on the displayed blank page.

Next, as shown in FIG. 6, it is assumed that the operator designates the previous page by a predetermined operation (process 601).
Then, the telewriting apparatus determines whether there is a previous page for the page being displayed (process 602), and if there is (Y in process 602), after transmitting a display command for all pages (process 603), the page is displayed. The image is displayed (process 604). If there is no corresponding page (process 602)
N), do not change the display.

By the way, after forming the communication link for telewriting, the telewriting apparatus constantly monitors the reception of the display command from the other party as shown in FIG. 7 (N loop of processing 701). . When the telewriting device receives a display command from the other party (Y in process 701), various displays are performed according to the command. That is,
When the drawing information is received, the image indicated by the drawing information is combined with the page image being displayed and displayed on the screen as in the case of the transmitting side. Further, in the case of the display command of the next page or the previous page, the display page is changed according to the designation (process 70).
2).

In this way, each telewriting device exchanges drawing information input by the operator while displaying the same image on the screen.

When the necessary communication is completed, the operator gives an instruction to end the communication as shown in FIG. 8 (process 80).
1). Then, it is determined whether or not to save the input image (process 802), and when saving (Y in process 802), the document file name is designated. At this time, for example,
If the user wants to change and save the document file, a new document file name is input, and if the current document file name is acceptable, the character input is omitted (process 803).

The telewriting device transmits a file save command to the other party (process 804). This file save command notifies the other party of the instructed document file name. Then, the input image combined with the document image is accumulated and saved in the image memory 109 with the designated document file name (process 805). In this case, the input image is also saved in the partner device as well.

As described above, in this embodiment, when the page designated by the operator exceeds the total number of pages of the document, a blank page is added to the document and the blank page is displayed on the screen. I have to.

Therefore, even if the operator runs out of space for inputting an image while exchanging drawing information on one document, a blank page can be added by performing a page feed operation. Image input can be continued. This eliminates the troublesome work of previously providing a blank page in a document and eliminates the need to create a new document during communication, thereby enabling efficient telewriting communication. become.

Even if the designated page exceeds the total number of pages of the document, if the last page at that time is a blank page, no new blank page is added.
As a result, it is possible to prevent unnecessary blank pages from being added one after another due to an erroneous operation by the operator.

In the above embodiment, the blank page is added to the end of the document, but it may be added to the page position designated by the operator.

If a document file name is not designated at the start of telewriting communication, a blank page document may be automatically created and displayed.

Further, although the call is made on one of the B channels of the ISDN line and the drawing information is transmitted on the other side, the call signal and the drawing information may be multiplexed and transmitted on one B channel. .

Further, an example of executing telewriting communication by ISDN has been described, but PSTN can also be used in the case of performing multiplexed communication as described above.

[0043]

As described above, according to the present invention, when the page designated by the operator exceeds the total number of pages of the document at the time of displaying the document, a blank page is added to the document, Since the blank page is displayed on the screen, there is no need for the troublesome work of previously providing a blank page in the document as in the past, and there is no need to create a new document during communication. You will be able to execute efficiently.
