Abstract

PURPOSE:To prevent a document, forbidden to be transmitted, from being transmitted by mistake by distinguishing between a transmissible remote party and the non-transmissible remote party, based on the information of a storing means, and displaying the list of the remote parties which are transmissible or non- transmissible, by a displaying means. CONSTITUTION:When the document to be transmitted is completed, or the document is intended to be transmitted, a destination designation picture frame 31 is displayed on the display part. The displayed contents are the list 32 of the basic terminal characteristic of the transmissible remote parties, the list 33 of a group dial, the list 34 of one touch dial, and the list 35 of an abbreviated dial. Also, the abbreviated dial 36 of a designated destination, the abbreviated dial 37 of the destination, which can be designated, and the abbreviated dial 38 of the destination, which is impossible to be designated, are shown. Thus, because before a circuit is connected at the step that the transmission is started, the remote parties can be displayed while the transmissible remote parties and the non-transmissible parties being distinguished, it can be decided even by any operator whether the document in question can be transmitted to the transmission destination or not.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mixed-mode facsimile, and more particularly, to a mixed-mode facsimile that forms an image by transmitting or receiving an image consisting of a pattern image and character data. be.

[Prior Art] In conventional mixed-mode terminals, an operator determines whether a document to be sent (hereinafter simply referred to as a document) can be sent to a destination communication terminal based on the document structure of the document and the destination terminal. This had to be done in consideration of the characteristics of the document exchange format and presentation functions.

[Problems to be Solved by the Invention] Therefore, since the operator must have a certain degree of understanding of communication technology, it is not easy for anyone to operate and is not user-friendly.

In addition, documents that cannot be sent are often accidentally sent to the other party's terminal, and from the time the line is connected until the line is disconnected when it is determined that document exchange is impossible as a result of presentation function negotiation. They had to bear the charges imposed during the period of use.

The present invention has been made in view of such prior art, and is a mixed mode facsimile that makes it possible to distinguish and clearly display destination terminals to which a document can be transmitted and terminals to which it cannot be transmitted, before transmitting the document. This is what we are trying to provide.

[Means for solving the problem] In order to solve this problem, the present invention has the following configuration.

That is, in a mixed mode facsimile that transfers or receives image information consisting of image components of an image pattern and a character code to form an image, a storage means that stores the type and function of the data communication device of each destination. a discriminating means for discriminating between a destination to which the image information can be transferred and a destination to which it cannot be transferred, based on image constituent elements constituting the image information and information stored in the storage means; and a discrimination by the discriminating means. A display means is provided for displaying a list of destinations that distinguishes between destinations to which the image information can be transferred and destinations to which the image information cannot be transferred, based on the results.

[Operation] In the configuration of the present invention, based on the information stored in the storage means, the discriminating means distinguishes between the destinations to which transmission can be made and the destinations to which transmission cannot be made, and the display means indicates the destinations to which transmission is possible or not. The above list is displayed by the display means.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram of a mixed mode facsimile according to this embodiment.

In the figure, reference numeral 1 denotes a control unit that controls the entire device, and operates according to a program stored in an internal program memory la. Reference numeral 2 represents an image reading section for reading images, and reference numeral 3 represents a document creation section for creating documents, which is equipped with a keyboard and the like. Reference numeral 4 denotes a display section for displaying read images, created documents, etc., and displaying messages to be described later. 5 is a table storing the type and function information of the destination terminal. , 6 is a transmission/reception control unit that controls the transmission and reception of data via the line. 7 is a printer that prints out received images and the like.

The operating principle of the mixed mode terminal device of this embodiment having the above-described configuration will be explained.

Mixed-mode facsimile is a G4 facsimile machine based on the CCITT (International Telegraph and Telephone Consultative Committee) recommendations, and as shown in Figure 2, the image pattern area (herein referred to as Pl) in the image of one page and the characters This is a device that sends or receives an image containing a mixture of rectangular areas of character areas (01 to C3) consisting of codes, etc.0 When sending the image shown in the figure to a mixed mode terminal, it is necessary to send the pattern and character information as is. However, when the destination terminal sends a message to, for example, a conventional terminal device of 63 or less, the characters in the area C1 to C3 are first converted into a pattern, and all of them are sent as a pattern. Furthermore, if all the information on the page is in characters, the destination terminal can transmit it as TTX (Teletex). Note that each of the above-mentioned rectangular areas pi, ci to C3 will be referred to as a block hereinafter.

In this embodiment, when the creation of a document to be transmitted is completed or when the document is about to be transmitted, a destination designation screen is displayed on the display section 4 as shown in FIG. 3. In the figure, 31 is a destination designation screen, 32 is a list of basic terminal characteristics of destination terminals that can be sent, 33 is a group dial list, 34 is a one-touch dial list, and 35 is a speed dial list. Also, the highlighted column 36 shows the speed dial for the specified destination, 37 shows the speed dial for the destination that can be specified, and the hanging column 38 shows the speed dial for the destination that cannot be specified. It is.

In this way, at the sending stage, before actually connecting the line, it is possible to distinguish and display the destinations to which transmissions can be made and those to which transmissions are not possible, so that any operator can First, it can be determined whether this document can be sent. Furthermore, since the decision can be made before connecting the line, there is no need to pay line charges.

Therefore, in this embodiment, the processes shown in FIGS. 4(a) to 4(d) are executed to determine whether the created document can be transmitted or not. The following will explain according to this flowchart.

In this embodiment, when a document to be transmitted is designated and a transmission destination is specified, the maximum page size Ps (ie, A4, B5 size, etc.) is calculated from each page of this document (step 5201).

Next, in steps 5202 and 5203, the character interval Cp and the encoding attribute of each block (ie, pattern or code) are extracted, and the maximum number of blocks Bn is also extracted.

Next, in step 5251, it is determined whether the maximum number of blocks Bn of the page of interest is "1" and its encoding attribute is a character code, that is, whether the entire page of interest consists of character codes (characters). to judge. When this determination is "Yes", the terminal characteristics BCs of the transmission destination are BCs = (FAX, MIX, TTX). Yes, the judgment in step 5251 is “Yes”.
” indicates that the destination terminal may be a facsimile, a mixed mode facsimile, or a teletex.

Further, in step 5252, the maximum number of blocks Bn is 1
It is determined whether or not <Bn<31 is satisfied. This number 31 means the maximum number of blocks in one page in mixed mode according to the CCITT recommendation. If this judgment is “Yes”, the terminal characteristics B Cs
= (FAX, Ml)t). When “No”, that is, when the number of blocks Bn is 31 or more, it is not possible to transmit in mixed mode, so the terminal characteristic BCs = (F
AX).

When the destination terminal elements to which the document created in steps 3204 to 206 can be transmitted are determined in this manner, the specifiable destination terminal characteristic elements are displayed in step 5207. For example, terminal characteristics B CS = (FA
X, MIX), the basic terminal characteristics list 32 in FIG. 3 will appear.

Next, in step 3208, the operator specifies the basic characteristics to be transmitted. For example, you can specify whether to send the created document in mixed mode or by facsimile. Furthermore, Figure 3 shows (Basic terminal characteristics list 32
), indicating that mixed mode is specified. Also, although the explanation may be confusing, these various settings can be specified by operating a pointing device such as a mouse, by using an icon that moves on the display screen, or by using a keyboard, etc. .

Next, in step 5200, matching is performed with the destination terminal that became capable of transmitting in step 5207, based on the transmission characteristics specified in step 5208.

At this time, the specified transmission mode is Teletex (TT
In the case of X), the processing from step 3211 onwards is performed. In step 5211, it is determined whether the destination terminal has TTX basic characteristics.

If the judgment at this time is "NO", step 321
8 to indicate that transmission to the specified destination is not possible. In addition, when “Yes”, step 52
12, the page size Ps of the document you are trying to send
Determine if is an optional size larger than the basic teletex page size. If this judgment is “No”, the process moves to step 5214, but here it is “Yes”.
That is, a case will be explained in which transmission is performed using a basic page size. In this case, the process moves to step 3213, and it is determined based on Table 5 whether the destination terminal supports the option size. If this determination is "No", the process returns to step 5218, and a message indicating that transmission is not possible is displayed. If the determination is "Yes", the process goes to step 5214, and the character spacing CP is an optional family.
s/1nch), and if 'Yes', then it is determined whether the destination terminal has this option.Next, if the final document to be sent is a character It is judged whether or not, but with this judgment "N"
Of course, if the determination is 'Yes', then the process moves to step 5218, since it is not possible to transmit by teletex, and a message indicating that transmission is not possible is displayed.If the determination is 'Yes', step 52
17, a message indicating that transmission is possible is displayed. In FIG. 3, the shaded destinations in the displayed list of destinations indicate that transmission is not possible, and the other destinations indicate that transmission is possible. Also, the destination specified by the operator (of course, it must be a destination that can be sent)
will be displayed with black and white reversed.

On the other hand, if it is determined in step 5200 that the mode is mixed mode, the processing from step 5220 onwards will be performed.

That is, it is determined whether the destination terminal is in mixed mode (step 5220), whether it is in the CP option (step 5221), and if it is in the CP option, it is determined whether the destination terminal is in the CP option. .

If it is determined that the destination terminal is a facsimile, it is determined in step 5224 whether the destination terminal is a facsimile.

As a result of the above processing, the operator can see at a glance whether or not the document can be sent to the destination before connecting the line.

By the way, as a feature of the mixed mode terminal device, when transmitting a document, it is possible to select whether to emphasize clarity or transmission efficiency.

FIG. 5 is a flowchart of a method of functions added to the above embodiment so that the clearness of transmitted documents and good transmission efficiency, which are characteristics of the mixed mode communication terminal device, can be utilized without bothering the operator.

Note that this flowchart continues from step 5209.

When specifying a destination that can be specified (for example, speed dial "*02" in FIG. 3) (step 5401),
Figure 4. Basic terminal characteristics existing as elements of the basic terminal characteristics set registered in the destination are extracted from the BCs obtained in the processing process and the basic terminal characteristics set (FAX, MI
A subset BCs' of X, TTX) is calculated (step 5402). From then on, this BCs' (FAX, MI
X) (7) Case (step 5413 and subsequent steps) will be described.

First, in step 5413, the operator inquires of the user whether he wishes to transmit the document at low transmission cost, communicate with a clear image, or otherwise. If it is desired to reduce the transmission cost, the process moves to step 5417, and this document is converted into two ways, one each as a MIX document and as a FAX document. However, the pixel density, which is one of the parameters passed to the conversion, is determined by the variety of pixel density attribute values of the presentation function of the destination (because the basic terminal characteristics may differ between MIX and FAX, in the MIX document, Among the pixel density varieties corresponding to a certain basic terminal characteristic, in the case of a FAX document, the one with the minimum value including the option family is selected from among the pixel density varieties corresponding to the basic terminal characteristic which is FAX.

Next, the FAX document and the MIX document with the smaller amount of data are selected for each block, and the corresponding basic terminal characteristics are automatically set as the basic terminal characteristics at the time of transmission (step 541).
8) Step 5419: Set the minimum pixel density variety among the pixel density varieties corresponding to the specified basic terminal characteristics.
), inform the operator.

On the other hand, if you want to maximize the clarity of the document, set the basic terminal characteristics to MIX (step 5420), and select the pixel density used in the document from the pixel density variety corresponding to the destination MIX. Set to the value that is equal to or most similar to the density. Furthermore, if none of the above is true, the operator is asked to specify the basic terminal characteristics and pixel density settings by presenting BCs' and the pixel density variety of the destination, respectively.

Also, BCs' (FAX, MIX, TTX) (
In case 7), that is, when it is determined that the created document contains only character information, the processing from step 5408 onwards will be performed, but the processing from steps 5408 to 410 will reduce the transmission cost and when emphasis is placed on clarity. In step 5412, the transmission mode is set to TTX. In other cases, the pixel density is specified in step 5411, and the data is transmitted as facsimile or mixed mode.

Further, when BCs' is (FAX), step 840
4 or less processing will be performed. That is, when emphasis is placed on transmission cost, the pixel density is minimized in step 5422. Also, when focusing on clarity,
The pixel density is set to be equal to or similar to the editing pixel density.

As explained above, according to this embodiment, even if you have no knowledge of communication technology, it is easy to specify the destination, and there is no possibility of accidentally sending a document that cannot be sent, thereby reducing the cost of using the line. be able to.

Furthermore, the operator can easily specify the advantages of mixed mode terminals, such as high transmission efficiency and high clarity of received documents.

In this embodiment, in order to distinguish between the recipients to whom the document can be sent and the recipients to which the documents cannot be sent, one is hung on a rope and displayed, but it is only necessary to make them distinguishable, and the present invention is applicable to this. It is not limited.

[Effects of the Invention] As explained above, according to the present invention, it becomes easy to specify a destination even without knowledge of communication technology, and it also eliminates the possibility of accidentally sending a document that cannot be sent. Cost can be reduced.
