Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile device that performs reading or recording using a rotating drum.

Generally, when communicating using the above-mentioned facsimile machine, the size of the recording paper on the receiving side is fixed, so
When a small-sized document is sent from the sending side, there is a considerable amount of blank space on the receiving side's recording paper.

For example, if the size of the document to be sent on the sending side is B5 and the size of the recording paper on the receiving side is B4, half of the recording paper will be a blank space. In reality, this is not a big problem if you are sending only one small document, but if you are sending multiple documents in succession,
Recording paper loss can no longer be ignored. Further, due to the diversification of facsimile devices, a similar problem arises when a plurality of documents are sent from a facsimile device with a small maximum reading size to a facsimile device with a large maximum recording size. The present invention has been made in view of the above-mentioned problems. When the sending side sends small-sized originals one by one, the receiving side sends the large-sized originals one by one.
To provide a facsimile device that can continuously record a plurality of transmission documents on a sheet of recording paper.

An embodiment of the present invention will be described below with reference to the drawings.

Note that the drawing is a block diagram of a facsimile apparatus according to an embodiment of the present invention. First, since the operator of the facsimile machine on the sending side knows the size of the recording paper 25 on the receiving side in advance, he calculates how many sheets of the transmission document 2 can be recorded on the recording paper 25, and then switches the rotary switch 13. Adjust the scale.

That is, when four originals 2 can be transmitted and recorded on one recording paper 25, the scale of the rotary switch 13 is set to "4". Note that when there is only one original document 2 to be transmitted, or when the size of the original document 2 to be transmitted is large and only one sheet can be recorded on the recording paper 25, the rotary switch 13 is turned ``OFF''. The case where the scale of the rotary switch 13 is set to "4" will be described below.

The transmission document 2 is automatically loaded onto the rotary drum 1 by a rotary paper feeder (not shown), and is scanned in the main scanning direction by the rotation of the rotary drum 1 and in the direction of arrow a by the movable table 3 on which the reading head 4 is mounted. The transmission original 2 is read and scanned by the sub-scanning caused by the movement. A signal obtained by reading and scanning the transmission document 2 by the reading head 4 is input to the reading circuit 5. In the reading circuit 5, the input signal is binarized. The binarized signal is modulated in the modulation circuit 6 and sent to the exchange 12 and the line 14.
It is then transmitted via the exchange 15 to the facsimile machine on the receiving side.

The signal input to the receiving side is demodulated by the demodulation circuit 16, and the demodulated signal is input to the recording circuit 17. The recording circuit 17 supplies the input signal to the recording head 23 mounted on the movable table 22 as a signal suitable for the recording method of the facsimile machine on the receiving side. At this time,
A recording paper 25 is attached to a rotating drum 24 on the receiving side, and the rotating drum 24 rotates for main scanning, and the moving table 22 is moved in the direction of arrow b, which is the sub-scanning direction, by a driving means (not shown). Move to. The recording head 23 is
It moves in the direction of arrow b together with the moving table 22 and records the same characters, figures, etc. as those on the transmission original 2 on the recording paper 25. By the way, the reading head 4 on the transmission side is moved in the direction of arrow a by four driving means (not shown), and the reading scan of the transmission original 2 is completed.

In addition, a magnet 10 is placed by the operator at a position corresponding to the rear end of the transmission document 2, and a read switch 11 attached to the moving table 3 is turned on as soon as it approaches the magnet 10.
", and outputs a signal to the sub-scanning control circuit 7 to inform that the reading scan of the transmission document 2 has ended. At this time, the movable table 3 returns to the sub-scanning start position. The sub-scanning control circuit 7 When the signal is received from the switch 11, it outputs the signal to the control circuit 8.At this time, the control circuit 8 modulates the signals since the number of signals from the sub-scanning control circuit 7 has not reached the number specified by the rotary switch 13. A sub-scanning stop signal is output to circuit 6. Modulation circuit 6 modulates this sub-scanning stop signal and transmits it to switch 12, line 14 and switch 15.
The signal is output to the demodulation circuit 16 on the receiving side via. Demodulation circuit 1
6 is a control circuit 1 which demodulates the sub-scanning stop signal from the transmitting side.
Output to 9. When the control circuit 19 receives the sub-scanning stop signal, it outputs a signal to the sub-scanning control circuit 20. When the sub-scanning control circuit 20 receives a signal from the control circuit 19, it temporarily stops a drive device (not shown). Therefore, the moving table 22
The recording head 23 then stops at the end position of the first transmission original 2, and recording of the first transmission original 2 on the recording paper 25 is completed. Next, the first transmission document 2 is transferred to the rotating drum 1 by means not shown.
After that, the second document 2 to be sent is transferred to the rotating drum 1.
will be installed on the At this time, if the sizes of the first and second transmission documents 2 are different, the magnet 10 will be placed at a position corresponding to the end position of the second transmission document 2. When the loading of the second transmission original 2 is completed, a drive device (not shown) is started, and the movable table 3 and reading head 4 move in the direction of the arrow again to start reading and scanning the second transmission original 2.

The explanation of the subsequent operation on both the sending and receiving sides is exactly the same as the operation for the first sent document 2, so it is omitted here, but the recording operation for the second sheet starts from the point at which recording of the first sheet ends. It turns out. Thereafter, the third and fourth transmission originals 2 are read and scanned in the same manner. When the reading scan of the fourth transmission document 2 is completed, the reed switch 11 becomes "0N" and a signal is output from the sub-scanning control device 7 to the control circuit 8.

When the signal from the sub-scan control circuit 7 is input four times, the control circuit 8 outputs a scan end signal to the modulation circuit 6.
The modulation circuit 6 modulates the scan end signal and sends it to the receiving side demodulation circuit 16 via the exchange 12 line 14 and the exchange 15.
Output to. The scan end signal demodulated by the demodulation circuit 16 is input to the control circuit 19 . When the control circuit 19 receives this signal, it outputs the signal to the sub-scanning control circuit 20. When the sub-scan control circuit 20 receives the scan end signal from the control circuit 19, it sets the read switch 21 to 00N°. When the reed switch 21 turns “ON”, the moving base 22
Then, the recording head 23 returns to the sub-scanning start position.
Therefore, four transmission originals 2 are continuously recorded on the recording paper 25. When the recording is completed, the control circuit 19 outputs a reception end signal to the modulation circuit 18. The reception end signal is modulated by the modulation circuit 18 and sent to the exchange 15,
Demodulation circuit 9 on the transmitting side via line 14 and exchange 12
is input. When the control circuit 8 receives this reception end signal, it automatically stops the facsimile machine. In addition,
In this embodiment, the facsimile receiver is limited to a cylindrical scanning type, but it can also be used as a flat scanning facsimile receiver that cuts recording paper to a fixed length or uses only a fixed length of recording paper. The present invention is applicable. As described above, according to the present invention, when the sending side successively sends small size originals one by one, multiple sheets of the sending originals are continuously sent to one recording paper of a predetermined size on the receiving side. The recording paper can be used effectively.

In particular, by appropriately setting the number-of-sheets designation means, the size of the document to be transmitted can be arbitrary, and it is characterized by a high degree of freedom in use.
