Abstract

PURPOSE:To stop transmission operation by the transmitting side by giving warning to the transmission side by the receiving side when the remaining amount of storage paper on the receiving side is the length or less by equivalent to a sheet of the original. CONSTITUTION:When the receiving side detects that the recording paper has only the remaining amount of the length equivalent to a sheet of the original by a detector 15 before starting facsimile communicaction, the signal without the recording paper is transmitted from the detector 15 to a controller 16. A signal having no recording paper is transmitted from a controller 16 to a CPU17. Then, it is transmitted that there is no recording paper in the receiving side from the CPU17 to the CPU17 on the transmitting side through a line 21. Then, the CPU17 displays on a warning device 18 that there is no recording paper. On the other hand, the transmitting side receives the information having no recording paper from the receiving side through the line 21 for the CPU17. The CPU17 allows a controller 9 to stop entering the original reading operation. Then, the CPU17 allows the warning device 18 to excute the warning without the recording paper.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a facsimile machine, and more particularly to a facsimile machine that uses recording paper divided into rolls.

[Prior Art] In a facsimile machine that uses a roll of recording paper, even when the remaining amount of recording paper on the receiving side is low and there is not enough recording length for one original document, the receiving side cannot accept the transmission from the sending side. When a request is made, the recording operation is stopped when there is no more reception.

However, the sending side continues to transmit until it has finished reading one page of the original, and at the point when it has finished reading one page of the original, it detects an abnormality on the receiving side and displays an error. Then, after the receiving side set a new recording paper, the sending side had to resend the document when an error occurred again, which was a waste of time and effort.

[Purpose] The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional technology.If the remaining amount of recording paper on the receiving side is less than the length of one original document, the receiving side can communicate with the sending side. It is an object of the present invention to provide a facsimile device configured to issue a warning so that the sending side can cancel the sending operation.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

Figure 1 and the following diagrams explain one embodiment of the present invention.
The figure shows a schematic configuration of a facsimile machine.

In FIG. 1, the reference numeral A indicates a transmitting section, and the reference numeral B indicates a receiving section.

In the transmitting section A, the one indicated by the code 1 is the original, and the motor 3
It is moved by feed rollers 2, 2 driven by.

Also, the reference numeral 4 is a light source that emits reflected light 5 from the original 1.
The optical path of the image is changed by a mirror 6, and the image is input to a solid-state image sensor 8 via a lens 7, where the image is converted into an electrical signal. The solid-state image sensor 84F- is controlled by the control device 9.

Further, in the receiving section B, a recording paper indicated by reference numeral 10 is sent out by a roller 11.11 driven by a motor 12.

The reference numeral 13 is a recording device that performs recording by sandwiching the recording paper 10 between it and a roller 13a.

Reference numeral 14 indicates a recording paper wound into a roll.

A detector 15 is provided near the roll of recording paper 14 to detect the remaining amount of recording paper.

Motor 12. Recording device 13. The detector 15 is the control device 16

On the other hand, what is indicated by the code 17 is the CPU (Central Processing Unit)
The control unit 9.16 and the warning device 18. which issues a warning when there is no remaining amount of recording paper. Modem 19, network control device 20
is connected to.

The reference numeral 21 indicates a line.

Next, the operation of the apparatus configured as above will be explained.

That is, on the receiving side, the operation shown in the flowchart shown in FIG. 2(A) is performed.

That is, in step S1, when the detector 15 detects that the remaining recording paper is not long enough for one document before starting facsimile communication, the detector 15 records it in the control device 16 in step S2. Signals can be transmitted without paper. Then, in step s3, the control device 16 notifies the CPU 17 that there is no recording paper.

Next, in step S4, the CPU 17 and the CPU on the sending side
17 via the line 21, the receiving side informs that there is no recording paper.

Subsequently, in step S5, CP [J17 is the warning device 18
“No paper” is displayed.

On the other hand, on the transmitting side, as shown in Figure 2 (B),
In the amplifier T1, the CPU 17 receives the information that there is no recording paper from the receiving side via the line 21.

Then, in step T2, the CPU 17 causes the control device 9 to stop starting the original reading operation.

Then, in step T3, the CPU 17 causes the warning device 18 to issue a warning that there is no recording paper.

By the way, in Figure 3, both the transmitting side and the receiving side are connected to the CCI.

Next, the receiving side issues a CFR (reception preparation confirmation signal), the sending side sends image information, and when all the image information has been sent, an EOP (message end signal) is issued, and the receiving side issues an MCF (message confirmation signal). signal) is sent, and then a DCN (disconnect command) is issued from the transmitting side to end the transmission.

In addition, HDLC (High-1 level d) is shown in Fig. 4.

In the present invention, in order for the receiver to notify the transmitter that there is not enough recording paper left for one original document, the receiver sends the message by putting the information that there is no recording paper in the NSF frame facsimile information field of the output signal of the receiver. Just send it to the machine.

On the other hand, the procedure for transmitting and receiving binary signals when transmitting a plurality of original documents is shown in FIG.

If the receiver detects that the remaining amount of recording paper on the receiver side is not long enough for the next document while sending multiple originals, the receiver sends the MCF frame at the page break to the transmitter. It is sufficient to notify the user that there is no recording paper by not sending the paper.

Furthermore, even in devices equipped with a detector that can detect when the remaining amount of recording paper is extremely low, even though it is longer than the original - Autumn Equinox, it is possible to stop the transmission operation and issue a warning in exactly the same way. can.

[Effects] As is clear from the above description, according to the present invention, a detector is provided to detect that the remaining amount of the roll of recording paper is extremely small, and this detector can detect that the remaining amount of the recording paper is extremely small. When this is detected, the receiving side can send a signal to that effect to the sending side to stop the sending operation, thereby eliminating the needless effort of resending the original.
