Further, in claim 2, when the received image length for the received data is less than or equal to the recording paper length, the received data including the source data is recorded on the surface of the recording paper. On the other hand, if the received image length is greater than or equal to the recording paper length, the source data is separated from the received data, the first recording device records the received data other than the source data on the surface of the recording paper, and the second recording device records the received data other than the source data on the surface of the recording paper. The sender data is recorded on the back side of the recording paper.

〔Example〕

FIG. 2 is a schematic configuration diagram showing an example of a facsimile apparatus according to the present invention.

The facsimile machine has a first recording section 1 and a second recording section 2.
and a reading section 3.

The first recording section 1 includes a recording head 12, a platen roller 13, and the like. In addition, in order from upstream in the feeding direction,
A paper feed cassette 14° 15 containing standard size recording paper (not shown) such as A4, 85, and paper feed rollers 16,1.
7. A pair of registration rollers 18 and 19 are provided, by which recording paper is fed to the first recording section 1. Then, the document received from the transmitting station side and, if necessary, the source data are recorded on the front side of the recording paper by the recording head 12.
The recorded recording paper is conveyed to the second recording section 2 side by a platen roller 13.

The second recording section 2 is provided downstream of the first recording section 1 in the conveying direction, and includes a recording head 20, a platen roller 21, and the like. If necessary, the source data is recorded on the back side of the recording paper by the recording head 20, and the recorded recording paper is conveyed downstream by the platen roller 21. Further, a discharge roller 22, a paper discharge tray 23, etc. are arranged downstream in the conveyance direction, and the recording paper conveyed by the platen roller 21 is placed on the paper discharge tray 23 via the discharge roller 22. There is.

Note that the reading section 3 includes a lamp 24 and a plurality of mirrors 25 to 2.
7, an optical lens 28, a CCD 29, etc. Then, the transmission document (not shown) is inserted into the document insertion slot 10.
The light from the lamp 24 is reflected by the original to be transmitted, and the reflected light is guided to the optical lens 28 via the mirrors 25 to 27. It is read and converted into image data.

Then, source data is added to the image data and transmitted to the receiving station as transmission data. The original tray 30 is used to place a transmission original inserted through the original insertion slot 10. Further, the sensor 31 detects that the leading edge of the recording paper is conveyed to the first recording section 1.
The sensor 32 detects that the leading edge of the recording paper has been conveyed to the second recording section 2.

FIG. 1 is a block diagram showing an example of a control system in the facsimile machine.

The NCU 4 connects a telephone line when communicating with another station, and releases the telephone line when communication is completed. The modem 5 demodulates the received signal from the NCU 4, and
At the time of transmission, the transmission signal from the control unit 7 is modulated and the NCU 4
This is what is output to. The encoding/decoding section 6 decodes the signal from the modem 5 and sends it to the control section 7 during reception, and encodes the signal from the control section 7 and sends it to the modem 5 during transmission.

The control section 7 is composed of a microcomputer, etc., and controls each section of the facsimile machine. The control unit 7 also controls the size (hereinafter referred to as
A function that compares the received image length (referred to as the received image length) and the recording paper length, a function that extracts and separates the source data from the received data, and a function that compares the received image length and the recording paper length as described below. It has a function to change the recording position. The page memory 8 is for storing source data from a transmitting station and image data of a transmitted document. Source memory 9
is for storing source data when necessary, as will be described later.

Next, an example of the operation of the facsimile machine having the above configuration will be explained using the flowchart shown in FIG. Note that, as described above, the received data includes the sender data and the image data indicating the received document.

When communication with the transmitting station is started and the first page of data is received from the transmitting station, the received data is stored in the page memory 8 in step S1.

In step S2, the control unit 7 determines whether the received image length of the first page is less than or equal to the recording paper length, that is, whether all the received data of the first page can be recorded on the surface of the recording paper. If the received image length is less than or equal to the recording paper length (YES in step S2), all of the received data on the first page can be recorded on the surface of the recording paper, so in step S3 the leading edge of the recording paper is aligned with the first recording paper. When the leading edge is conveyed to the first recording unit 1 (YES in step S3), the leading edge is stored in the page memory 8 in step S4.
The received data is read out from the recording paper and recorded on the surface of the recording paper.

Then, when the above received data is recorded, step S5
It is determined whether the data of the next page has been received or not. If there is no received data of the next page (No in step S5), communication with the transmitting station is terminated, and if there is received data of the next page (step S5). (YES), the process returns to step S1 and the next page of received data is stored in the page memory 8.

On the other hand, if the received image length of the first page is equal to or greater than the recording paper length in step S2 (No in step S2), for example, if the received original and the recording paper are the same size, the length of the recording paper is equal to the source data. Therefore, the source data is separated from the received data stored in the page memory 8 and stored in the source memory 9 in step S6. On the other hand, the page memory 8 only contains image data representing the received original.

Next, in step S7, wait until the leading edge of the recording sheet is conveyed to the first recording unit 1 (NO in step S7), and when the leading edge is conveyed to the first recording unit 1 (Y in step S7).
ES), the presence or absence of image data in the page memory 8 is determined in step S8.

If there is image data in the vane memory 8 (YES in step S8), for example, a predetermined number of lines of image data is read out from the page memory 8 in step S9, and the first
The recording unit 1 records the information on the surface of the recording paper. That is, only the image data of the received document is recorded on the front surface of the recording paper. On the other hand, if there is no image data in the page memory 8 (NO in step S8), the process moves to step S10 without performing the process in step S9.

In step S10, the leading edge of the recording paper is located at the second recording section 2.
It is determined whether the leading edge has been conveyed to the second recording unit 2 (NO at step 810).
), the process returns to step S8. On the other hand, when the leading edge is conveyed to the second recording unit 2 (YES in step S), it is determined in step S whether or not there is source data in the source memory 9. If there is source data in the source memory 9 (YES in step Sll), the source data is read out from the source memory 9 by, for example, a predetermined number of lines in step S12, and is stored in the second recording section. 2 is recorded on the back side of the recording paper. On the other hand, if there is no source data in the source memory 9 (NO in step 311), step S
The process moves to step S□3 without performing the process of L2.

In step S□3, it is determined whether there is data in the page memory 8 or the source memory 9, and if there is data in either the page memory 8 or the source memory 9 (YES in step s13), the first page Since the recording of the received data has not been completed, the process returns to step S8. On the other hand, if there is no data in either the page memory 8 or the source memory 9 (NO in step S13), the recording of the first page of received data has been completed, and the process moves to step S5.

In this way, if the received data, including both the sender data and the image data representing the received original, is recorded on the recording paper, it will extend beyond the recording paper. By recording the sender data on the back side of the recording paper, the received data Prevents data from protruding from the recording paper.

Note that the arrangement position of the second recording section 2 is not limited to the arrangement position shown in FIG. 2, and may be arranged upstream of the first recording section 1 as long as it is a position where recording can be performed on recording paper.

In addition, regardless of the length of the received image, the source data is always separated from the received data, and the received data other than the source data is recorded on the front side of the recording paper, and the source data is recorded on the back side of the recording paper. You may also do so. Furthermore, it may be possible to select whether the sender data is always recorded on the back side of the recording paper using a selection switch or the like.

Further, it is not necessary to separately store the source data and the image data in separate memories as in the above embodiment, but they may be stored in the same memory so that they can be distinguished (separated). Furthermore, in the above embodiment, the source data is added to the image data to obtain the received image length. ) is added to the received original to determine the received image length.
Dimension comparison may also be performed.

〔Effect of the invention〕

In the present invention, since the source data is recorded on the back side of the recording paper, the source data does not overlap with the document, and it is possible to prevent the source data from affecting the reading of the document. Further, if the original is the same size as the recording paper, there is no need for extra recording paper such as one that adds source data to the beginning of the original, and waste of recording paper can be prevented.

Also, if the received image length is longer than the recording paper length, the source data is recorded on the back side of the recording paper, so if the received image length is less than the recording paper length, the source data can be checked on the front side of the recording paper. I can do it.
