Conventionally, a plurality of paper feed cassettes can be attached to a facsimile apparatus, and a user operates an operation key to preset the size of the recording paper so that the recording paper of the set size is accommodated. Some of them have a function of taking out recording paper from the paper feeding cassette and printing it.

[0004]

However, when the size of the transmission original on the calling side is larger than the set recording paper size, in the conventional facsimile apparatus, is it printed reduced on the recording paper? Or, since it is printed on a plurality of sheets, there is a problem that the printed characters are difficult to read or the recording paper is wasted.

By the way, the size of the transmitted document is relatively determined for each calling terminal in many cases, and even if it is not uniquely determined, the size frequently used for each calling terminal is almost determined. Often Therefore, if the size of the recording paper can be switched for each calling terminal at the time of reception, it is considered that the above problem can be solved to some extent.

The present invention has been proposed in view of the above points, and it is an object of the present invention to provide a communication device capable of switching the size of a recording sheet according to a calling terminal at the time of reception.

[0007]

In order to achieve the above object, the communication apparatus of the invention described in claim 1 uses identification information for identifying a calling terminal from reception information input via a communication line. Identification information detecting means for detecting, storage means for storing various information relating to the calling terminal in association with the identification information, recording means for printing an image on a recording sheet based on the image information included in the received information, A communication device having a recording paper selection means for selectively supplying a plurality of types of recording papers of different sizes to a recording means, wherein the recording means stores the size of the recording paper as information on the calling terminal. The size input means and the size of the recording paper corresponding to the calling terminal are judged by searching the storage means on the basis of the identification information detected by the identification information detection means at the time of reception. And a recording sheet size determination means for supplying to the recording means recording sheet size corresponding to the calling terminal by controlling the recording paper selection means based on the cross-sectional results.

In this communication apparatus, if the size of the recording paper is stored in the storage means as the information relating to the calling terminal by the recording paper size input means, the recording paper size discriminating means receives the identification information detecting means by the identification information detecting means. The storage means is searched based on the detected identification information to determine the size of the recording sheet corresponding to the calling terminal, and the recording sheet selection means is controlled based on the determination result to correspond to the calling terminal. A size recording sheet is supplied to the recording means.

Therefore, according to this communication device, the received image can be printed on the recording paper having a size corresponding to the size of the transmission original used by each calling terminal. For this reason, it is possible to prevent the characters and the like from being reduced to make them difficult to see, and to prevent the recording paper from being wasted due to being printed on a plurality of sheets.

Although a facsimile machine can be considered as the communication device, the present invention is not limited to this, and the present invention can be applied to various electronic devices such as a copying machine or a personal computer having a built-in modem.

The communication line may be wired or wireless, and may be a public line or a dedicated line.

An EEPROM can be considered as the storage means, but the storage means is not limited to this. For example, a hard disk or M
Various storage media such as O, PD, and RAM with power backup can be used.

A thermal transfer printer is conceivable as the recording means, but is not limited to this, and various printers such as an ink jet printer and a laser printer can be adopted.

It is well known that the recording paper selection means selectively takes out the recording paper from a plurality of paper feed cassettes containing the recording paper made of cut paper. However, the leading end of the recording paper made of roll paper is selectively selected. Alternatively, the configuration may be changed so that it is supplied to the recording means.

The recording paper size input means may be constructed such that the user inputs the size of the recording paper for each calling terminal by using the operation keys, or every time image information is received. In addition, the size of the transmitted document is calculated from the number of lines of each page of the received image, and the calculated size is EEPR
The size may be stored in a predetermined area of the OM or the like, and when the same size is continuously stored a predetermined number of times for the same calling terminal, the size may be stored in the storage means.

The identification information may be a caller ID (hereinafter referred to as "Caller ID") which is inserted between call signals before the circuit is closed and is transmitted. However, the identification information is not limited to this. It may be an identification code or the like transmitted from the calling terminal after the connection.

The communication device of the invention described in claim 2 is the communication device according to claim 1, wherein the identification information is a caller ID (C) sent from the switching center before the line is closed.
Aller ID), and a proxy receiving means for storing the received information in the storage means when the recording paper of the size judged by the recording paper size judging means cannot be supplied to the recording means by the recording paper selecting means. It is a thing.

In this communication device, when the recording paper of the size judged by the recording paper size judging means cannot be supplied to the recording means by the recording paper selecting means,
The substitute receiving means stores the received information in the storage means. For example, when the recording paper of the size corresponding to the calling terminal is out of paper, so-called memory proxy reception is performed in which the received information is stored in the RAM. Of course, the storage means is not limited to the RAM.

Therefore, according to this communication device, in addition to the effect of the communication device according to the first aspect, the recording paper of the size judged by the recording paper size judging means can be supplied to the recording means by the recording paper selecting means. When, the received information can be read from the storage means and recorded.

Further, the communication device of the invention described in claim 3 is the communication device according to claim 1, wherein the identification information is a caller ID (C) sent from the exchange before the line is closed.

In this communication device, when the recording paper of the size judged by the recording paper size judging means cannot be supplied to the recording means by the recording paper selecting means,
The circuit closing prohibition means prohibits circuit closing. For example, when the recording paper of the size corresponding to the calling terminal is out of paper, the line is not closed. Since the line is not closed even after the lapse of a predetermined time, the calling terminal determines that there is no recording sheet and can perform processing such as notifying the user of that fact.

Therefore, according to this communication device, in addition to the effect of the communication device according to the first aspect, the size of the recording paper corresponding to the calling terminal can be determined before the line is closed, and the recording paper of that size is selected. When printing is not possible, the fact that the line is not closed can be notified to the calling terminal.

In S15, the size corresponding to the calling terminal specified by the identification code is the ID of the EEPROM 6.
If not stored in the table (S15: NO), that is, the calling terminal specified by the identification code is EEP.
If it is not registered in the ID table of the ROM 6 or if it is registered but the information regarding the calling terminal does not include the size of the recording paper, the CPU 1 causes the EEP
It is determined whether or not the size of the recording paper is stored in a predetermined area other than the ID table of the ROM 6 (S20). This size setting does not correspond to each calling terminal, but the size of the recording paper generally used for all calling terminals whose size is not registered in the ID table can be set in advance by the user. The operation unit 13 is operated to set the values. If the size of the recording paper is stored in the predetermined area of the EEPROM 6 (S20: YES), the CPU 1
Determines whether or not a recording sheet of that size is present in the paper feed unit 23 based on a signal from the paper feed unit 23 of the recording unit 12 (S21). If the recording paper of that size is present in the paper feed unit 23 (S21: YES), the process proceeds to S17, the recording paper of that size is fed to the printer unit 22, and the subsequent processing is executed to print the received image. To do.

In S21, if the recording paper of the specified size does not exist in the paper feeding section 23 (S21: NO),
In order to proceed as the paper is out, the process proceeds to S9 and the line is opened. The received image may be printed on a recording sheet of the maximum size that can be fed.

In S20, if the size of the recording paper is not stored in a predetermined area other than the ID table of the EEPROM 6 (S20: NO), the size of the recording paper cannot be specified, so the process proceeds to S9 and the line is opened. The received image may be printed on a recording sheet of the maximum size that can be fed.

If the identification code of the calling terminal is not input through the telephone line 21 in S14 (S14:
No), the CPU 1 determines whether or not the timer started in S13 is up (S22).
If the timer has not timed out (S22: N
O), and returns to S14 and waits for the identification code of the calling terminal to be input via the telephone line 21. That is, since the identification code is not always input at the moment of closing the line, the input of the identification code is waited for a certain time.

In S22, if the timer is up (S22: YES), the process proceeds to S20 and the subsequent processes are executed. That is, since the identification code is not input and the calling terminal cannot be specified, the processing when the size of the recording paper is not specified is advanced.

In S1, if the call signal is not input through the telephone line 21 (S1: NO), the process returns to S1 and waits for the call signal to be input.

Thus, when the Caller ID or the identification code is input and the size of the recording paper corresponding to the calling terminal specified by it is stored in the ID table of the EEPROM 6, the received image is recorded on the recording paper of that size. Printed.

In the above embodiment, if a recording sheet of the specified size does not exist in the paper feeding section 23, the routine is executed without closing the line in order to notify the calling terminal of that fact. Although the processing is ended, the line may be closed and the reception information may be stored in the RAM 3. By doing so, the recording paper of the specified size is fed to the paper feeding unit 2.
3, the received information can be read from the RAM 3 and recorded.
