Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a function of storing transmitted or received image data in an image memory and then transferring it as logging data to a recording terminal device registered in advance, that is, a so-called remote copy function. The present invention relates to improvement of a communication terminal device.

2. Description of the Related Art A communication terminal device such as a facsimile device has a function of storing transmitted or received image data in an image memory and then transferring it as logging data to a recording terminal device registered in advance, so-called remote copy. Some have functions.

Here, the logging data is transmitted to a memory,
When a facsimile machine having a memory reception function transmits image data to another facsimile machine or receives image data from another facsimile machine,
The transmitted image data and the received image data are transferred to a recording terminal device such as a personal computer and recorded and saved.

[0004]

However, in the conventional communication terminal device, when the sent and received image data (original image data) is stored in the memory and printed, the logging data is transferred to the recording terminal device. The image data is transmitted in the same size.

Therefore, in the recording terminal device, the amount of data to be recorded and stored for this logging data becomes large, so that the required memory capacity is increased, and when the recorded and stored logging data is printed out on the recording paper. Has a problem of increasing the consumption of recording paper more than necessary.

The present invention has been made in consideration of the above circumstances, and it is possible to reduce the memory capacity of the recording terminal device in which the logging data is recorded and saved, and also to consume the recording paper for printing and outputting this. It is an object of the present invention to provide a communication terminal device having a remote copy function that can save power.

[0007]

In order to achieve the above-mentioned object, the communication terminal device according to claim 1 saves the transmitted or received original image data in an image memory and then records it in advance. In a communication terminal device having a function of transferring as logging data to a terminal device for use, original image data is reduced in a predetermined format and transferred as logging data.

Here, the logging data is obtained by reducing the transmitted or received original image data in the main scanning direction and / or the sub-scanning direction at a predetermined reduction ratio, or by thinning the lines in the sub-scanning direction. , Is transferred to the recording terminal device and stored.

According to a second aspect of the present invention, in the communication terminal device according to the first aspect, the logging data is transmitted by reducing the original image data transmitted from the communication terminal device to the receiver to the size actually transmitted. It is characterized by

In this case, for example, when transmitting communication image data of B4 size from the communication terminal device of the transmission source, when the communication communication device of the receiving side of the receiving side has a function of receiving only the image data of A4 size. The source communication terminal device transmits the reduced image data corresponding to the document size that the receiver can receive. In such a case, the recording terminal device receives the reduced image data from the source communication terminal device. The image data, which is the same size as the one that was actually transmitted earlier, is obtained by reducing the original image.

In this case, for example, image data of a document read and scanned at a reading pitch of 3.85 LPM is
If the logging data is transmitted at 7.7 LPM, the consumption of recording paper for printout can be cut in half without deterioration of image quality.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a basic conceptual diagram of an image data transmission system to which the communication terminal device of the present invention is applied.

Although a facsimile machine (multi-function machine) is used as the communication terminal device here, the present invention is not limited to this, and may be a telephone or a personal computer having a communication function.

In the figure, 1 is a communication terminal device (source FAX) of the present invention, and 2 is another communication terminal device (reception destination F).
AX) and 3 indicate a recording terminal device composed of a personal computer or the like.

In this communication terminal device 1, an NCU for controlling connection to the communication line L1 (or L2) by a main control unit, a modem for modulating / demodulating signals for facsimile communication, an image memory for temporarily storing image data. ,
A RAM that stores various data, a ROM that stores a control program in advance, a display unit that includes a liquid crystal screen and LEDs, an operation unit that includes various operation keys, a reading unit that reads an image from a set original, It has a recording unit that prints out the received and scanned images on a preset recording paper, and stores the original image data that was sent or received in the image memory and then records it in advance. It has a so-called remote copy function of transferring as logging data to the terminal device 3.

Here, the remote copy function means image data transmitted to another communication terminal device 2 by the communication terminal device 1 having a memory transmission / memory reception function or image data received from another communication terminal device 2. 4 (both original image data) is transferred to a specific recording terminal device 3 registered in advance as a storage destination of history data.

In the communication terminal device 1 of the present invention having such a remote copy function, the original image data 4 transmitted to the other communication terminal device 2 or received from the other communication terminal device 2 is used as a recording terminal. When transferring the original image data 4 to the device 3 as the logging data 5, the original image data 4 is not transferred as it is, but is reduced in the main scanning direction and / or the sub scanning direction, or the line in the sub scanning direction is thinned out. And then try to transfer.

In the figure, the portion indicated by 6 is history reference information of logging data, which is added for convenience of later retrieval, and the transmission date and time is recorded as a time stamp, and logging for the original image data 4 is performed. Data 5
The reduced information is added.

According to the present invention as described above, since the logging data 5 is transferred to the recording terminal device 3 after reducing the original image data 4 into a predetermined format, the logging data 5 is recorded and saved. It is possible to reduce the memory capacity required for the terminal device 3 for use, and it is also possible to reduce the consumption of the recording paper for printing and outputting this.

FIG. 2 is a diagram showing the basic concept of an image data transmission system using another communication terminal device of the present invention.

Here, the same parts as those in FIG. 1 are designated by the same reference numerals and the description thereof will be omitted.

In this example, the original image data 4 transmitted from the communication terminal device 1 to the reception destination is reduced according to the reception capability of the communication terminal device 2 at the reception destination.

For example, when the receiving destination has only A4 size receiving capability, the B4 size original image data 4 is reduced to A4 size transmission data 4'according to the receiving capability of the receiving communication terminal device 2. Is transmitted by facsimile, and in this case, the communication terminal device 2 of the receiving destination is included in the recording terminal device 3.
The image data reduced to A4 size transmitted to the server is transferred as the logging data 5.

Therefore, in the case of this example, as the logging data 5, reduced data having the same size as the image data transmitted to the receiver is transferred.

FIGS. 3 and 4 are flowcharts showing the basic operation of the communication terminal device of the present invention. FIG. 3 shows a procedure for sending and receiving image data, and FIG. 4 shows a procedure for transferring logging data.

The basic operation of the communication terminal device of the present invention will be described below with reference to these figures.

In the image data transmission / reception routine of FIG. 3, first, at the time of facsimile transmission from the communication terminal device 1 to another communication terminal device 2, the original is read at the specified resolution, and the read image data is read. , Encoded as original image data and stored in the image memory.

Then, the communication terminal device 2 of the other party, which is the recipient, is called and, in accordance with the normal facsimile communication procedure,
The communication terminal device 1 at the receiving end communicates with the protocol signal, and the image data is transmitted in a size matching the receiving ability of the receiving end.

That is, if the communication terminal device 2 of the other party has a sufficient receiving function, the stored image data is transmitted in the same size, but the communication terminal device 2 of the other party transmits up to A4 size image data. When there is only a function to receive, the original image data is reduced in size according to the receiving capability of the other party and transmitted, the transmitted size is stored, and the line is disconnected when the facsimile transmission is completed. Step 1 of 3
00-step 106).

On the other hand, when the communication terminal device 1 receives image data from another communication terminal device 2, the received original image data is encoded and then stored in the image memory (above,
Step 105 in FIG. 3).

Next, in the logging data transfer routine, if the previously registered recording terminal device 3 is called and reduced transmission is set, steps 202 to 20 are executed.
8 is executed to transfer the logging data with a preset reduction ratio and reduction method, but if such reduction transmission is not set, the original image data is reduced to the size actually transmitted. The image data is transferred as logging data (step 211).

That is, when the reduced transmission is set, it is determined whether the line thinning is set or not. When the line thinning is set, the scanning is performed according to a preset set value. The line is extracted for each predetermined line, but when the line thinning is not set, the resolution at the time of reading is determined. For example, the resolution is 3.85 LPM.
If set to, the transmission resolution is 7.7 and DC
