Abstract

PURPOSE:To stop message recording and to output a proper post message response by the processing of the receiving side by inhibiting the reception of an unnecessary message or a message including an error and sending a proper response to the transmitting side. CONSTITUTION:When a STOP +P key is detected during the reception of a message on the receiving side R, message rejecting/interrupting means processing 1 is started and recording operation is stopped. However message reception and decoding and procedure control are continued. The transmitting side T continues the sending of a message for one page, sends an RTC on the end of the message, and at the time of receiving the RTC, the receiving side R shifts operation to procedure control processing. In the case of single page transmitting procedure processing 2, the transmitting side T sends an EOP indicating the execution of a post message instruction and the receiving side R receiving the EOP sends an MCF to send a false response indicating the message is normally received. After receiving the MCF, the transmitting side T sends a DCN and then disconnects a line. The receiving side R also disconnects the line after receiving the DCN and normally ends the operation but does not record an unnecessary message.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile control system suitable for use in a facsimile machine having a manual reception function.

0002

[Prior Art] The facsimile procedure control system is CCI
TT Blue Book Volume VII-FASCICLE V
It is described in detail in II-3 (P.91 to P.113). FIG. 2 shows a conventional procedure control system.

FIG. 2A shows a control method when a one-page message and a plurality of pages of messages are sent and received using standard procedure processing 8. In the case of a message with only one page, the sending side T continues to send the message to the receiving side R until the end of the message, and after the end of the message, RTC (Ret
urn to control), then EO
At the point when P (End of procedure) is sent, the receiving side R sends the MCF (Mess) of the complete received signal.
age confirmation), and RTN (Retrain negative) of incompletely received signals.
e) respond with a post message such as; The sender T that received this post message receives the DCN of the disconnection start signal.
(Disconnect) to disconnect the line. Note that printing and recording by facsimile is performed sequentially at the time when a message from the sending side T is received, while the receiving side R performs a decoding process.

[0004] Furthermore, when the message has multiple pages, after transmitting the message of one page and RTC, MPS (Multi-page S
ignal). On the receiving side R, after printing and recording the message, it replies with MCF or RTN. When a complete reception MCF is returned, sender T sends the next page of messages and RTC, and receiver R performs print recording. When the message transmission is completed, the sender T sends an EOP, and the receiver R replies with an MCF.
CN is sent and the line is disconnected. On the other hand, M on the sending side T
When the receiving side R returns a signal RTN indicating incomplete reception in response to PS transmission, the transmitting side T sends out a digital command signal DCS and a training check signal TCF. Receiving side R receives these signals and replies with reception preparation confirmation signal CFR. After this, messages etc. are transmitted from the transmitting side T, and when all messages are finished, a DCN is transmitted and the line is disconnected.

[0005] The above is the case during normal reception, but the CCITT Blue Book does not specifically specify the case where the receiving side R issues a reception stop during message reception. As an example, assume that the receiving side R is powered off to forcibly stop message reception on the receiving side R.

FIG. 2(b) shows a control method in the case of forced stop. In reception forced termination procedure process 9, the sending side T:
The message continues to be sent until the end of the sending page regardless of the receiving side R, and a post message command is sent to the receiving side R.
However, if the receiving side R has already stopped operating as described above, the response signal cannot be received. Therefore, the transmitting side T performs a retry process (EOR transmission twice) at 3-second intervals, then sends a DCN and disconnects the line, but the transmitting side T ends up in a procedure control error.

[0007]

[Problem to be solved by the invention] Receiving side (operator)
An example of requesting suspension of processing while receiving a message is:
Examples include when unnecessary messages such as direct mail are sent, or when an error occurs in the message.

[0008] In the above conventional example, when the receiving side interrupts message reception, it stops receiving the message and returns to the standby state, but the sending side suffers a procedure control error, and the error occurs due to a message error or a procedural error. I can't tell if it's an error. Furthermore, depending on the model of the sending side, some models perform the sending process again, which causes the receiving side to receive unnecessary messages again.

[0009]

[Means for Solving the Problems] The above problem consists of a means for issuing a reception interruption process by pressing a specific key, and a means for issuing a reception interruption process by pressing a specific key.
means for stopping only print recording of received messages and continuing message reception processing, decoding processing and procedure control;
The problem is solved by providing means for selecting the type of response command by means of a key combination.

0010

[Operation] When the operator on the receiving side presses a specific key, the receiving side immediately stops the message print recording process, but continues the decoding process while detecting a received message, and starts the decoding process when an RTC is detected. Stop and move to procedural control processing. The receiving side sends a post message response in response to the post message signal sent from the sending side. The post message response is selected by the receiving operator's key operations, and several types of responses can be sent by one type or a combination of several types of keys.

[0011] When a message interruption is issued by key operation, the receiving side uses MCF as a response signal, and from this, the sending side judges that the message has been successfully transmitted and issues DCN.
is sent, and the procedure control ends normally. Even if the message has multiple pages, decoding processing and procedure control are performed in the same way as in normal times, except that the receiving side does not perform recording processing. In either case, the receiving side completes normally without recording any unnecessary messages.

[0012] When issuing a message error abort, the receiver responds with an RTN. The sending side determines that the message could not be completely transmitted, sends a DCN, and disconnects the line. However, since message error information is stored on the sending side, the message is sent again from a sending side that has retransmission capability, such as a memory device. In this case, the receiving side resumes the recording operation. In the case of multi-page transmission, the transmitting side transmits messages for the next page and subsequent pages after receiving the RTN, so the receiving side can restart the recording operation and receive messages.

[0013]

Embodiment FIG. 1 shows an embodiment of the present invention. Table 1 shows key operations and operations during reception in this embodiment. P and N in the key operation column of Table 1 are, for example, numeric keys (0, 1,...
・Allocate to 9). Furthermore, in the following embodiments, the transmitting side T will be described as executing a standard procedure.

[0014]

[Table 1]

In FIG. 1, when the receiving side R detects the STOP+P key (after pressing the STOP key, releases the finger and then presses the P key), message rejection interruption procedure process 1 is executed. In this case, the receiving side R immediately stops the recording operation after detecting the key. However, message reception, decoding, and procedure control continue. The sender T continues sending one page of messages and sends an RTC at the end of the message. When receiving side R detects RTC, it shifts to procedure control processing. For single page sending procedure process 2, sender T sends an EOP in a post message command. Receiving side R, which has detected EOP, sends an MCF and makes a pseudo-response that the message has been successfully received. The sending side T is M
After receiving CF, it sends DCN and disconnects the line. Receiving side R also disconnects the line after receiving the DCN and normally ends the procedure, but no unnecessary messages are recorded. In the case of multi-page transmission procedure process 3, the sender T sends an MPS in a post message command. The receiver R responds with an MCF, and the sender T sends the message again after receiving the MCF. The receiving side R continues to receive the message, decode it, and control the procedure, but does not record the message. The subsequent processing is the same as for single page transmission. In addition, STOP
After pressing the +P key, the status of the transmitting side T becomes normal as shown in Table 1, and a good image is transmitted.

If the STOP+N key is pressed while receiving a message, the message error interruption procedure process 4 is executed. The receiving side R immediately stops recording after detecting the key. The sender T sends a post message command after sending the RTC. In the case of single page transmission process 5, the sender T sends an EOP. In response, the receiving side R sends an RTN signal,
Returns a response that the message was not completely received. The transmitter T, which has received the RTN, sends the DCN and disconnects the line. At this time, information indicating that message transmission is incomplete is stored on the sending side T. In the case of multi-page transmission process 6, the transmitter T sends the MPS as a post message command. In response, the receiving side R responds with RTN. The error information is stored on the sending side T, but the standard procedure is to send the next page of messages. Receiving side R again STOP+P, STOP+N, STOP+STOP
Unless any of the keys is detected, the message is printed and recorded, and the key detection flag is cleared when reception starts from the second page onward. Note that some transmitters T transmit DCN without transmitting a message again when receiving RTN. In that case, the receiving side R only has to disconnect the line after receiving the DCN. Also, after pressing the STOP + N keys, the sending side T
In the state shown in Table 1, the procedure ends normally, but a good image is not transmitted.

If the STOP+STOP key is detected during message reception, the reception forced termination processing procedure 7 is entered. This is the same process as the conventional procedure. Stops print recording and procedure operations at the same time. However, in this case, the procedure ends abnormally on the sending side.

[0018]

[Effects of the Invention] According to the present invention, it is possible to stop receiving unnecessary messages or messages with errors, and to respond appropriately to the sender, thereby preventing reception of direct mail and resending messages. This has the effect of improving operability, such as not recording pages with requests or errors.
