2. Description of the Related Art Generally, a facsimile machine is installed at a predetermined place, and a plurality of users go to the place and set and transmit a document.

[0003] At this time, the user is near the facsimile apparatus until the original is read, and after that, the facsimile apparatus automatically dials and transmits.

[0004] In the case of facsimile reception, the user rarely stays near the facsimile apparatus from the beginning.

In such a situation, when the power is turned off (cut off) during construction or the like during facsimile transmission / reception, the user goes to the location of the facsimile apparatus within the influence range and checks the operation state of the facsimile apparatus. Although it is necessary, in practice such work is cumbersome and often difficult.

Therefore, a facsimile apparatus has been proposed which has a report function for notifying when power is turned off during transmission / reception when power is restored (for example, Japanese Patent Application Laid-Open No. 8-228270). Reference).

[0007]

However, even if a report indicating that the power supply has been shut down during transmission / reception has been issued when the power is restored, the user who checks the report is rare, and the transmission is mostly completed. I thought that I was doing,
In some cases, this could cause trouble later.

Therefore, the present invention makes it easier and more effective to detect that a power interruption has occurred during transmission and reception when the power is restored.
An object of the present invention is to provide a facsimile apparatus capable of surely informing a user.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a facsimile apparatus applied to the description of the embodiment of the present invention.

The facsimile apparatus has a system control unit 11, a reading unit 12, a recording unit 13, a modulation / demodulation unit 14, a network control unit 15, an operation display unit 16, an image information storage memory 17, an information holding memory 18, and the like. I have.

The system control unit 11 includes the information holding memory 1
In accordance with the control program written in 8, each device is controlled.

The reading unit 12 has 3.85 lines / mm, 7.7
This is for obtaining an image information by reading a document image at a predetermined reading line density such as book / mm, 15.4 book / mm or the like.

The recording unit 13 is for recording and outputting the received image information according to its line density, and for recording and outputting the image information read by the reading unit 12 according to its line density.

The modulation / demodulation unit 14 modulates / demodulates image information and various transmission signals. The network control unit 15 is connected to the line to detect the inversion of the line polarity, close / release the DC loop of the line, and release the line. It performs connection control such as detection, detection of a dial tone, detection of a tone signal such as a busy tone, detection of a call signal, and the like.

The operation display section 16 is provided with ten keys, a start key, a one-touch dial key, and other various keys for designating a destination telephone number, and a liquid crystal display (L).
A display device such as a CD) is provided to display the operating state of the apparatus and various messages to be notified to the user.

The image information storage memory 17 temporarily stores the image information read by the reading unit 12 as a file for memory transmission, or temporarily stores the received image information as a file until the received image information is recorded by the recording unit 13. It is used as a temporary storage area for storing.

The information holding memory 18 is constituted by an SRAM or the like so that the stored contents can be held even when the power is cut off, and stores the control program for the system control unit 11 to control each unit as described above. Various kinds of information such as information for identifying the operation state of the facsimile apparatus when the power is cut off, information for specifying the transmission destination as required, and information to be displayed on the display of the operation display unit 16 are stored. ing.

Next, the operation of such a facsimile machine will be described. When the facsimile apparatus starts reception and memory transmission, a reception operation flag indicating that transmission / reception is being performed is turned on, and a request to change the display content of the display is made.

At this time, as the information displayed on the display unit, a display indicating that transmission / reception is in progress is performed as shown in FIG. 2, and then the destination name, transmission / reception state (number of sheets, communication mode) according to the communication state. ) Etc. are displayed.

FIG. 2 is a diagram showing a case where the display information on the display unit is data in a bitmap data format.

FIG. 3 is a diagram showing an example of a transmission / reception procedure, in which a line is established for a call from a calling side, and a calling tone CNG.
Is called (phase F1), and the called party responds to the call with the called station identification signal CED (phase F1).
2).

At this time, immediately after the start of the reception, the called side sets the reception operation flag to ON ("ON") and makes a display request that the reception is being performed.

In response to the digital identification signal DIS and the non-standard function identification signal NSF sent from the called side (phase F3), the calling side sets the digital transmission command signal D
CS sends out the non-standard function setting signal NSS (phase F4).

At this time, information necessary for displaying the name of the calling side and the like is obtained from the transmitter terminal name defined in the NSS (non-standard function setting signal).

The system control unit 11 creates bitmap data based on the information, transfers the bitmap data to the operation display unit 16, and displays the data on a display.

After setting communication parameters in phase F4, the calling side performs modem training at the modem speed set by the training check signal TCF (phase F5), and receives a reception preparation confirmation signal CFR from the called side. (Phase F6), and transmits the image information as a facsimile message (phase F7).

The data transmitted as a facsimile message in the phase F7 is not limited to image information, but is a BFT (Binary Fi) which is an extended function of the G3 facsimile.
leTransfer).

The calling facsimile apparatus is in phase F
When the facsimile message is transmitted in step 7, a procedure end signal EOP is transmitted (phase F8), and when the called side responds with the message confirmation signal MCF (phase F9),
The disconnection command signal DCN is transmitted (phase F10), and the facsimile transmission is completed.

When the facsimile transmission is completed normally, the contents displayed on the display are erased, and the operation flag is turned off ("OFF") to complete the facsimile communication.

During such transmission / reception, a power interruption occurs,
Thereafter, the process when the power is restored will be described with reference to the flowchart shown in FIG.

When the power is restored, it is determined whether or not the operation flag is on (step S1). Since this operation flag is set to ON when facsimile communication is started as described above, if the operation flag is OFF, it means that power supply has not been interrupted during communication. Therefore, in this case, the process proceeds to step S12 and enters a standby state.

On the other hand, when the operation flag is on, it means that the power supply has been interrupted during transmission and reception. (The information displayed on the display at the time of execution) is displayed on the display (step S).
2).

At this time, for example, the characters are inverted so that the information displayed on the display is the display contents before the power is turned off.

Thus, the user can determine whether or not the power supply has been interrupted only by checking the display state, that is, whether or not there is a case where the facsimile communication has not been normally performed. Therefore, appropriate and prompt response can be easily performed.

Then, a preset specified time is set and started (step S3). This time defines the display time performed in step S2 as described later.

Thereafter, it is determined whether or not there is a display erasure request (step S4). This display deletion request is made by the user operating the operation display unit 16.

If there is no display erasure request, it is determined whether a report print instruction has been requested (step S5).

The report print instruction indicates that the power supply has been cut off during transmission and reception. The system control unit 11 creates a report from the drawing data stored in the information holding memory 18 and the recording unit 13 Recording and output are performed (step S6).

Of course, if there is no report printing instruction, the report is not recorded and output, so that the report is issued only when it is necessary, thereby making it possible to save recording paper waste.

If there is no report printing instruction, it is determined whether or not an instruction has been given to the transmitting side to transmit information indicating that the power has been cut off during transmission / reception (step S7).

That is, if the communication is not completed normally, the necessity of retransmission occurs, so that image information as shown in FIG. 5, for example, is transmitted to inform the transmitting side (step S).
8).

Therefore, since the communication is not completed, the trouble of requesting the sender to resend is eliminated, and the convenience is improved.

In this case, since it is necessary to know the telephone number of the transmitting side in advance, the NSS (non-standard function setting signal) is transmitted so that the transmitting terminal number is transmitted from the transmitting side in advance. However, it is possible that the number is not defined in the NSS, so that the user can also input a number from the operation display unit 16 (step S
9, step S10).

Such processing is performed within the time specified in step S3, and thereafter, the facsimile apparatus turns off the operation flag and waits for transmission / reception (standby state) (step S12).
