Abstract

PURPOSE:To discriminate quickly a faulty state by storing all transmission condition data in order to transmit/receive picture information to a memory and outputting the data at a fault so as to analyze a fault part. CONSTITUTION:When the facsimile acts like a sender, every time a condition data from a remote receiver is received, it is fed to a memory 5 and a reception control section 4. The data representing a transmitting condition are fed to a transmission control section 1, where a transmission speed, line density and picture information size or the like are selected and the result is transmitted to a transmission section 2. Moreover, this information is fed also to the memory 5 and stored in succession to the data from the reception side. If a fault occurs in transmission, it is detected by a fault detection section 10 to be displayed on a display device informing the fault. Each data stored in the memory 5 is read manually or automatically in the order of the transmission/reception and outputted to a recording section 9.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a facsimile device that transmits facsimile images, and particularly relates to a facsimile device that transmits and receives images after transmitting and receiving control data to and from a partner station.

<Prior art> In a system that transmits and receives image information such as a facsimile, before transmitting and receiving the image signal with the other party's device, the transmission conditions of the image signal, such as the CCI of the facsimile, are determined.
Transmits and receives TT standards (C, II, GTI[, GN), linear density, encoding method, size of single-picture information (A4, B4, B5, etc.), etc.

That is, first, the transmitting station calls the receiving station, and the receiving station sends a tonal signal (a tone signal indicating that it is a facsimile machine), data identifying the functions of the receiving station, such as receivable transmission speed, encoding method, etc. , cotton density, received paper size, etc. The transmitting station matches its own function from among these,
The most efficient conditions with the shortest transmission time are selected and transmitted to the receiving station. After that, a training signal that can equalize line distortion is transmitted.

The receiving station activates its corresponding function in accordance with the notified conditions and receives the training signal.

When the receiving station receives the training signal and completes the training, it notifies the transmitting station of training completion data. At this time, if training is not sufficient and errors occur frequently, the receiving station notifies the transmitting station to that effect, lowers the transmission rate, and performs a so-called fallback.

In this way, when the preparation is completed, the transmitting station transmits the image signal. In addition, when the transmitted manuscript consists of multiple pages, when one page has been sent, data indicating that one manuscript has been completed and data indicating that it is a multi-page document is sent, and confirmation data from the receiving side is received. After that, the transmitting side transmits the next image signal.

Image signals are transmitted as described above, but generally, image signals and training signals are modulated using a high-speed modulation method and transmitted, and other various data are transmitted and received as low-speed data.

In such conventional systems, upon completion of normal transmission, a transmission confirmation mark is stamped on the back side of each original to be sent, thereby guaranteeing the transmission of the original. However, in conventional systems, the seal is stamped by a stamping mechanism when the transmission is completed, so even if a failure occurs during communication, it may be due to poor line conditions or the sending side It is not possible to determine whether there is a fault or even whether there is a fault on the receiving side, and furthermore, a sealing function is required just for guaranteeing, which has the drawback of increasing the size of the device.

<Objective of the Invention> The object of the present invention is to provide a small-sized facsimile machine that eliminates the drawbacks of the prior art, allows fault conditions to be identified.

<Structure of the Invention> In order to achieve the above object, in the present invention, each data transmitted and received outside of both signals is stored in a memory, and in the event of a failure, the data is outputted to an output means of an image recording device or the like that a facsimile receiver has. This is what was output.

<Embodiment> The drawing is a block diagram of a facsimile machine according to an embodiment of the present invention.

Since the figure shows a transmitter/receiver, a case where it simultaneously operates as a transmitter and a case where it operates as a receiver will be explained respectively.

a. When operating as a transmitting side, a telephone (not shown) reads out the other party's receiving device and receives 1-null signal condition data from the receiving station. When the receiving section 3 also receives the tonal signal and receives the condition data, each condition data is supplied to the memory 5 and the reception control section 4 each time it is received.

The reception control unit 4 recognizes that its own device is currently on the transmitting side based on an instruction from the main control unit (not shown), and when it receives data indicating transmission conditions from these receiving stations, it transmits the data. The signal is supplied to the transmission control section 1. The transmission control section 1 receives this condition data, selects the conditions matching the own device, such as the transmission speed of the image signal, the linear density 1-picture information size, etc., and sends this information to the transmission section 2. This information is also supplied to the memory 5 and is stored following the previously stored data from the receiving side. Thereafter, the transmission control section 1 operates the transmission section 2 so that it matches the transmission speed of the image signal in the condition data transmitted to the receiving side and causes the transmission section 2 to generate a training signal at that speed.

This operating information is also stored in the memory 5.

When the training signal is transmitted from the transmitter 2, the receiving side notifies whether the training was successful or unsuccessful. This notification signal is received by the receiving section 3.

The receiving unit 3 stores data indicated by the received signal in the memory 5 and notifies the reception control unit 4 of the data.

In the case of training failure, the transmission control unit 1 changes the transmission conditions and notifies the receiving side of the changed condition data. This operation is repeated in the same manner until a signal indicating successful training is received. Upon receiving the signal indicating training success, the transmission control section 1 sends the reading section 6. The compression unit 7 is activated to encode and compress the image read from the transmission document and transmit it.

After transmitting the image signal for one page, the transmission control unit 2
The transmitting unit 2 is notified to send a transmission end notification to the receiving side.

When the transmitted manuscript spans a plurality of pages, data to that effect is supplied to the transmitting section 2 and the memory 5 at this time. As a result, the transmitter 2 transmits the data signal.

The receiving side sends out a confirmation signal in response to this signal. The receiving section 3 receives this and supplies it to the reception control section 4 and memory 5.

b. When operating as a receiving side, the transmission control unit 1 transmits a tonal signal via the transmitting unit 2 in response to a call signal from the transmitting side. Next, the transmission control unit 1 transmits transmission condition data indicating its own receivable functions.
The signal is supplied to the transmitter 2 and transmitted.

When the receiving unit 3 receives the transmission condition data from the transmitting side,
According to the condition data notified to the reception control section 4, the reception control section 4 controls the reception section 3. The decoder 8 is set and put into operation. When the receiving section 3 receives the training signal, the reception control section 4 monitors the receiving training state via a line (not shown) and determines whether the training is successful or unsuccessful.

The determination result is notified to the transmission control unit 1. Transmission control section 1
supplies the data of the determination result to the transmitter 3 and causes it to transmit.

If the training is successful, then the image signal is sent to the receiving unit 3.
Receive.

The received image signal is decoded and expanded by the decoding section 8 and supplied to the recording section 9 .

In this case, the memory 5 stores data supplied by the transmission control section 1 to the transmission section 2 and data received by the reception section 3 and supplied to the reception control section 4 in the same manner as when operating as a transmission side. are stored in order.

If a failure occurs during C1 transmission/reception A failure is detected by the failure detection unit 10.

For example, the fault detection section 10 is configured to be able to connect to each of the above-mentioned sections or to monitor the status of each section, and also monitors time for abnormalities in the transmission procedure using a timer.

Once a failure is detected by the failure detection unit 10, the display 11 displays a message to that effect. Based on this display, a switch (not shown) is operated, or the fault detection unit 10
does not automatically read each data stored in the memory 5 in the order of transmission and reception.

The read data is supplied to the character generator 12, converted into a character pattern, and supplied to the recording section 9.

Thereby, the communication status up to that point can be output in symbols or numbers. In the above embodiment, all the condition data is stored in the memory, but it is not necessary to store all of the data, and only a part of the data or data indicating the action may be stored.

<Effects of the Invention> As explained above, according to the present invention, all the transmission condition data for transmitting and receiving image information are stored in order, so when a failure occurs, the failure part can be analyzed from that information. Moreover, since the recording section for reception is also used as the output section for these data, it is also possible to reduce the size.
