Abstract

PROBLEM TO BE SOLVED: To allow a transmitter side confirm in advance a resolution of an image to be outputted to a receiver side and to send the image after setting a read line density. SOLUTION: The facsimile equipment is provided with a storage memory 16 storing data of a transmission original, an information storage section 17 storing line density information of each page and a line density conversion section 18. After the transmission original is read into the storage memory 16 at once in the highest line density (super-fine or the like) of the equipment and the data are printed out while converting the line density into all the line density (fine mode and standard mode) of the equipment. Then the data are sent to the receiver with the line density designated by the user. Thus, the user confirms the state read by all the line density of the equipment before transmission and sends the data after setting the resolution again.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus which has a plurality of reading line densities of a document and which can be set by a user during a transmission operation.

[0002]

2. Description of the Related Art Conventionally, in a facsimile apparatus having a plurality of reading line densities of a document and being able to change the line density during a transmission operation, the following method has been used for transmitting a document. First, the sender determines, from the content of the original document to be transmitted, the reading linear density suitable for the page. That is, whether the read line density should be standard mode (or standard mode) or fine mode (or fine mode),
Further, whether or not the high definition mode (or the super fine mode) is necessary is determined from the size of the characters on the original document, the figure, and the like. At this time, some facsimile machines do not have the high-definition mode, and in that case, the standard mode or the fine mode is selected. Further, when there are a plurality of transmission originals, each mode is determined for each page by the method described above.

Thereafter, the original is set according to the transmission operation of the facsimile apparatus, the mode of the reading linear density determined by the user himself is set for each page, and the page is transmitted to the destination.

[0004]

However, in the facsimile apparatus having the above-described structure, the linear density of the read original is largely determined by the user's sense, and the linear density is determined by the user's experience and feeling. It is extremely ambiguous. When a manuscript to be transmitted is read at a certain linear density, it is not possible at the same time to know at what resolution the read is actually output to the other party.

Therefore, when it is unclear at which linear density the transmitted original should be transmitted, a copy operation is performed at each linear density in advance before the original is actually transmitted, and the output image is examined to determine the respective linear densities. It was necessary to perform a time-consuming and laborious operation such as checking the image quality at the density.

[0006] Yet another problem is resolution deterioration due to reduction. For example, if the transmitted document is B4
When the size of the receiver is A4 or the like, in a normal facsimile apparatus, the transmission data once read on the transmission side is reduced from B4 to A4 and transmitted. Generally, the reduction from B4 to A4 is generally performed by thinning out the data from the B4 data according to the reduction ratio. There is also a method of thinning out data according to an algorithm instead of simple thinning out as described above.

However, in this case as well, not all the information amount of the B4 original is sent to the receiving side. Therefore, the loss of information data due to the reduction is inevitable by any of the data thinning methods, and the resolution often deteriorates on the receiving side even though the linear density is properly selected by the user on the transmitting side. Moreover, the automatic reduction transmission that occurs at the time of such transmission is that the transmission actually starts and the capability (ITU-
Bits 17, 18 on the procedure signal DIS of the T recommendation T30:
It occurs only when the print width capability on the receiving side is known, and cannot be predicted by the sender. Therefore, the sender cannot know the substantial deterioration of the resolution due to the reduction unless the receiving side gives an indication.

The same can be said when the original on the transmitting side is A3 size. That is, even if the transmitting side attempts to transmit an A3 size original document to a B4 size or a facsimile apparatus having only A4 size receiving capability, the transmitting side will generate an A3 size document.
Since the document information of the size is reduced according to the receiving side, the resolution is deteriorated.

The present invention solves the above-mentioned problems of the prior art, requires no special operation at the time of transmission operation, can select an appropriate linear density corresponding to a document to be transmitted, and causes deterioration of resolution due to automatic reduction. It is an object of the present invention to provide a facsimile device that can notify the sender of the result even if it occurs.

[0010]

In order to solve the above-mentioned problems, the present invention comprises means for setting a reading linear density for each transmission original, and means for reading the transmission original into the storage memory at the maximum linear density of the apparatus. , Also has a means for converting the linear density from the maximum linear density to another linear density, and continuously prints the original information of each linear density converted by the linear density and the original information read at the maximum linear density before starting the transmission. By doing so, the user can be informed of the proper reading line density of each page.

According to the present invention, it is possible to select an appropriate linear density corresponding to a document to be transmitted without requiring a special operation at the time of transmission operation, and to obtain the result even if the resolution is deteriorated due to automatic reduction. A facsimile device that can notify the sender can be provided.

With this configuration, when the automatic reduction transmission is performed, it is possible to immediately notify the sender of the degree of resolution deterioration of the image output at the other end.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. (Embodiment 1) FIG. 1 is a block diagram of a facsimile apparatus according to Embodiment 1 of the present invention. In FIG. 1, 11 is a facsimile device, 12 is a scanner unit for reading a document at each linear density, 13 is an operation panel, 14 is a printer unit, and 15 is a printer unit.
Is a control unit for controlling the entire facsimile. Reference numeral 16 is a storage memory for storing transmission originals, 17 is an information storage unit for storing the linear density information of each page, 18 is a linear density conversion unit for converting the linear density of the original information once read into the storage memory, 20
Is a modem unit, 21 is a network control unit, 22 is a line connection terminal, 2
3 is a line.

In the following description, the maximum linear density of the apparatus will be 8 pel × 15.4 line / mm (high-definition mode or super fine mode), and the other linear densities will be 8 pel × 7.7 line / mm (fine mode or super-fine mode). , Fine mode) and 8 pel x 3.85 lin
e / mm (standard mode or standard mode).

The original sent by the user from the operation panel 13 of the facsimile apparatus 11 is scanned by the scanner unit 1.
In No. 2, the data is read in the superfine mode having the highest linear density of the apparatus and stored in the storage memory 16. At this time, the linear density information corresponding to each page is stored in the information storage unit 17. This operation is repeated for the number of documents set by the user. Therefore, all the originals that the user tries to send are stored in the storage memory 16 in the superfine mode, which is the maximum linear density of the apparatus, and the linear density information of all pages is stored in the information storage unit 17 as the superfine mode. . All of these controls are performed by the control unit 15.

After that, the apparatus reads the image information of the first page read out of the image information in the storage memory 16 from the printer section while converting the linear density from the super fine mode to the standard mode in the linear density conversion section 18. Printing is started, and the printing is temporarily stopped at about 1/3 of the recording paper, and the image information after that is printed from the printer unit 14 while converting the linear density from the super fine mode to the fine mode by the linear density conversion unit 18. To resume. When this operation reaches the position of 2/3 of the recording paper, the reprinting is interrupted, and the subsequent image information is restarted from the printer unit 14 at the linear density in the super fine mode until the end of the section. Print. Therefore, the image information of the first page of the original document that the user wants to send is printed on one recording sheet with all the linear densities of the apparatus.

Here, in the above description, each linear density was divided into 1/3 of the recording paper and printed.
It may be printed one by one. If the maximum linear density is in the fine mode, printing may be performed in the fine mode and the standard mode on each half of the recording paper.

Then, the facsimile machine 11 performs this operation for all pages. However, the printing operation can be stopped by the user during printing. FIG. 2 shows an example of the print sample output in this way.

By this series of printing operations, the user can confirm the read data of each page at each linear density by looking at the printed image output. At this time, the apparatus is waiting for the user to input a linear density change.
Therefore, the user sets the linear density required for each page on the operation panel 13
By inputting more, the line density information of each page in the information storage unit 17 can be changed to an appropriate one.

When the user inputs the line density for each page using the operation panel 13, the line density information of each page in the information storage unit 17 is rewritten according to the user's input. After inputting the line densities of all pages, the user operates the operation panel 13
The transmission can be started by.

When the user performs a transmission start operation, the apparatus shifts to the transmission operation, and the image information in the storage memory 16 is transferred to the linear density conversion unit 18 according to the linear density information of each page in the information storage unit 17. After the linear density conversion, the signal is modulated by the modem 20 and transmitted from the line connection terminal 22 through the network control unit 21 to the receiving side through the line 23.

As described above, according to the first embodiment, it is not necessary to perform a special operation such as once making a copy of an original at each linear density and confirming each resolution at the time of a transmission operation. It is possible to select an appropriate linear density.

(Second Embodiment) FIG. 3 is a block diagram of a facsimile apparatus according to a second embodiment of the present invention. In FIG. 3, reference numeral 25 is a facsimile apparatus according to the second embodiment. Reference numeral 12 is a scanner unit for reading a document at each linear density, 13 is an operation panel, and 14 is a printer unit, which are the same as those in the first embodiment. Reference numeral 15 is a control unit for controlling the entire facsimile, 16 is a storage memory for storing transmission originals, 17 is an information storage unit for storing linear density information of each page, and 18 is a linear density of original information once read into the storage memory 16. Is a linear density conversion unit, and 19 is a reduction unit that reduces the image information once read into the storage memory 16. Further, 20 is a modem unit, 21 is a network control unit, 22 is a line connection terminal, and 23 is a line.

The original sent by the user from the operation panel 13 of the facsimile device 25 is scanned by the scanner unit 1.
In step 2, the read line density is read by the user and stored in the storage memory 16. At this time, the line density information, the document width information, and the reduction information corresponding to each page are stored in the information storage unit 17. The document width information referred to here is the scanning width of the transmission document, and refers to the short sides of A3, B4, and A4 sizes. Further, the reduction information remains 100% for all pages because it has not been transmitted at this point. The operation up to this point is repeated for the number of documents set by the user. Therefore, all the originals to be transmitted by the user are stored in the storage memory 16 at the reading linear density designated by the user, and the linear density information, the original width information, and the reduction information of all pages are stored in the information storage unit 17. It All of these controls are performed by the control unit 15.

After that, the facsimile device 25 shifts to the transmitting operation, but the receiving side does not always have the same printing ability as the document width designated by the transmitting side. That is, even if the transmitting side attempts to transmit an A3 size document, if the receiving side has a printing capacity of B4 size or A4 size, the transmitting side reduces and transmits the document. Similarly, even if the sending side tries to send a B4 size document, the printing ability of the receiving side is A
Even in the case of 4 sizes, it is reduced and transmitted on the transmitting side.

In any case, even if the user of the facsimile apparatus selects the optimum read line density in the original size of the original to be transmitted, the result of communication is reduced transmission due to the capability of the receiving side, and reproduction at the receiving side. The resulting resolution will be unreadable and contrary to the sender's intent. So when sending,
When the image information stored in the storage memory 16 is reduced and transmitted by the reduction unit 19, the user is immediately notified of the reduction. As a result, although the linear density is properly selected by the user, the reduced transmission is automatically performed, and when it is highly possible that the other party has deteriorated resolution, the sender user immediately You can know that.

The facsimile machine 25, which has started the transmission operation, modulates the image information stored in the storage memory by the modem unit 20, sends it from the line connection terminal 21 to the line 22 through the network control unit 20, and sends it to the receiving side. At this time, if the printing capacity of the receiving side is lower than that of the sending side, that is, if the receiving side has a printing capacity of B4 size or less when the sending side has A3 size sending capacity, or the sending side has B4 size If the receiving side has only A4 capacity at the time of, the image information in the storage memory 16 is reduced to B4 size or A4 size by the reduction unit 19, and then modulated by the modem unit 20, and the network control unit. It is sent from the line connection terminal 22 to the line 23 via 21 and is sent to the receiving side.

At this time, the reduced information corresponding to each page in the information storage unit 17 is rewritten to the reduced information as a result of the transmission. That is, for example, reduction from A3 to B4, A3
To A4, B4 to A4, etc. Similarly, the facsimile device 25 processes all the image information in the storage memory 16, sends it to the receiving side, and finishes all the transmitting operations.

When the transmission is normally completed, the facsimile machine deletes the image information stored in the storage memory, which has been normally transmitted. However, here, the image information is not deleted from the reduced and transmitted page even if the communication is normally completed. As a result, only the reduced page of the original image information input by the user is stored in the storage memory 16 in the original size, and the information storage unit 17 stores the read linear density, the original width, and the reduced information corresponding to each page. Is remembered.

After that, the facsimile device 25 is reduced by the reduction unit 19 in the same manner as when the original-size image information in the storage memory 16 is reduced by the reduction information and the document width information in the information storage unit 17 and transmitted. The image is reduced and printed out from the printer unit 14. At this time, if only the image information is printed, it is confused with normal facsimile reception, so a message is attached to the beginning of the printed output. FIG. 4 is an example of a print sample printed out in this way.

The characteristic feature here is that even if the reduced transmission is performed,
This means that the image printed out on the receiving side can be reproduced on the transmitting side to some extent. Usually, in a facsimile machine, the transmitting side transmits the reduced data to the receiving side, so that the receiving side often prints out the received data without processing it.
In some cases, it may be processed on the receiving side in exceptional cases. This is the case, for example, when cut paper is used as the recording paper instead of roll paper.
Even if the image information of the size is received, it may be reduced on the receiving side due to the recording margin of the printing unit. In rare cases, when the print line density is higher than the line density for communication, the line density may be increased on the receiving side to print out.
That is, for example, the line density in communication is the fine mode (20
The linear density of the print is 300 though it is only up to 0 dpi)
This is the case when there is more than dpi.

However, in the former case, the resolution is further deteriorated, and in the latter case, only the apparent linear density is increased from the data sent from the transmitting side, and the image deterioration due to the reduction on the transmitting side is fundamental. It is not meant to be restored. In this way, in the facsimile machine, the data sent from the sending side is often printed out as it is, and even when the data is processed on the receiving side, the actual resolution is higher than the data sent from the sending side. Is few. Therefore, even when the transmission side is reduced and transmitted, the transmission side can reduce the image at the same ratio as the reduced transmission and print it out to reproduce the image information reaching the reception side to some extent. After that, the user can know the resolution actually transmitted to the receiving side by looking at the printed message and data.

As described above, in the second embodiment, when the reduced transmission is automatically performed, the user is informed, and the reduced page is reduced and printed on the paper after the transmission is completed in the same manner as at the time of transmission. With this configuration, the user on the transmitting side can immediately know the degree of resolution deterioration of the image output at the other party, and can immediately perform retransmission if necessary. .

[0037]

As is apparent from the above description, according to the present invention, the original is read into the storage memory at the maximum linear density of the apparatus before the transmission is started, and then converted into each linear density.
Since the printing apparatus is configured to print, the user of the facsimile device can check and transmit the image information in a state close to the resolution of the state of being printed and output to the receiving side in advance.

Further, when the manuscript information is reduced and transmitted, the reduced and transmitted page is printed together with the message in a reduced state, so that the resolution is deteriorated due to the reduction. However, the user can know the result.
