The system control unit 2 controls each part of the facsimile machine 1 according to a program in the ROM, and
At the same time, the telephone number comparison process, call stop process, and line disconnection process for preventing erroneous calls according to the present invention are executed.

The operation port (operation unit) 3 is equipped with various operation keys such as a one-touch program key, a numeric keypad, and a start key for selecting various transmission modes such as direct transmission mode and memory transmission mode, and is also equipped with a display (e.g., liquid crystal display). Through the operation, various commands are input, such as information on the destination telephone number and call operation in this embodiment, and input contents and various information transmitted from the facsimile machine 1 to the operator, especially memory transmission. Various messages necessary for error processing, such as destination phone number information related to normal calling operations, and already registered destination phone number information are displayed on the display. Further, it is assumed that the operation port 3 requires input of a predetermined password when specifying destination telephone number information during memory transmission. A handset 11 is also connected to the operation port 3, and normal dialing is also possible by taking the handset 11 off-hook.

Memory (Image memory, registration memo) 4 has a predetermined capacity and amount, and includes an image memory area for storing image information for sending, image information for receiving, etc., and a registration memory for registering the telephone number information of the destination to permit calling. As shown in FIG. 2, a call permission dial file is registered in the registration memory area to permit calling.

As the scanner 5, for example, a CCD (Charge
A line image sensor using a Coupled Device is used, and the scanner 5 reads the document line by line and outputs it as image data.

As the plotter 6, for example, a thermal recording device using a thermal element is used, and the plotter 6 records directly on thermal recording paper or indirectly on ordinary recording paper via an ink sheet.

The encoding/decoding device 7 encodes image information of a document according to a predetermined encoding method, and also decodes the encoded image information.

The scaling device 8 performs scaling processing of image information at a predetermined scaling factor.

During facsimile communication, the communication control unit 9 exchanges facsimile control signals with the other party's facsimile device and executes facsimile communication procedures.

A network control unit (telephone number detection means, line disconnection unit) 10 is connected to a line (for example, a telephone line), and the network control unit 10 sends and receives facsimile communication control signals to and from the communication control unit 9 to connect to the line. In this embodiment, the network control unit 10 also has the following functions (1) to (3).

(1) Function to detect whether the line is connected or not (2) Dial pulse signal or DTMF output to the line
(Dual Tone Multifrequency
) Function for detecting a signal (3) Forcibly disconnecting a line The functional network control unit 1O uses these additional functions to execute a line disconnection process during a normal call operation, which will be described later.

Next, the effect will be explained.

In this embodiment, when the operator operates the operation port 3 to specify the direct transmission mode, inputs the destination telephone number, and then presses the start key.

The system control unit 2 compares the input telephone number with the destination telephone number registered in the call permission dial file stored in the registration memory area, and if they do not match, A predetermined message indicating that the call has been stopped and the telephone number is different is displayed on the display of the operation port 3 to notify the operator. If they match, normal facsimile communication procedures are executed and image information transmission processing is started.

Furthermore, when the start key is pressed after the memory transmission mode is specified, a password is entered, and a destination phone number is entered, the system control unit 2 sends the input phone number to the sender that is stored in the registered memory area. It is compared to see if it matches the destination phone number registered in the call permission dial file, and if they do not match, the document image is not stored in the image memory area of memory 4 and the phone number that does not match is checked. A predetermined message is displayed on the display of the operation port 3 to notify the operator.

This notification prompts the operator to determine whether or not to erase the image information, and prompts the operator to continue the operation.

If the phone numbers match, the original image is stored in the image memory area of the memory 4, and at the designated call time after this storage, the input phone number is stored in the registration memory area again. The call is compared to see if it matches the called party's phone number registered in the call permission dial file. The message is displayed on the display of the operation port 3 and notified to the operator. If they match, normal facsimile communication procedures are executed and image information transmission processing is started.

Comparing phone numbers at the time of a call is not possible because the contents of the call permission dial file may be changed or the destination may be changed by the operator between the time memory transmission is instructed and the time the call is made. The operator may be able to arbitrarily set or cancel this telephone number comparison process at the calling time.

Furthermore, it is assumed that no image information is stored in the memory 4 during polling reception, similar to memory transmission.

Next, a description will be given of a process for preventing erroneous dialing when the operator operates the operation port 3 to put the handset 11 into an off-hook state, or lifts the handset 11 to put it in an off-hook state and performs a normal dialing operation.

In such a normal call operation, the off-footer state is entered by dialing the numeric keypad of the operation port 3 or by operating the handset 11 (however, in the case of the operation port 3, it can also be input using speed dialing, one-touch dialing, etc.). The telephone number information of the other party is output to the line through the network control section 10 when operating the hand center 11, and through the communication control section 9 and network control section 10 when operating the operation port 3. These series of line status and telephone number information output to the line are stored in the network control unit 1.
0 is detected by the above-mentioned function and notified to the communication control unit 9, and further notified to the system control unit 2 from the communication control unit 9.

So after being taken off-hook by the operator,
When the telephone number of the other party is entered by dialing, the information notified from the network control unit 10 during this time is monitored by the communication control unit 9, and the information on the line connection status and the telephone number information output to the line are sent to the system. The control unit 2 is notified. The system control unit 2 compares the notified telephone number information with the telephone number in the call permission dial file stored in the registered memory area of the memory 4, and if they do not match, the communication control unit 9 A line disconnection request is output, and a predetermined message to the effect that the line has been disconnected is notified to the operation port 3, displayed on the display, and notified to the operator. Upon receiving the line disconnection request from the system control unit 2, the communication control unit 9 instructs the network control unit 10 to disconnect the line, and the network control unit 10 disconnects the line. On the other hand, if the compared telephone numbers match, normal facsimile communication procedures are executed and image information transmission processing is started.

As described above, in the memory transmission mode of the facsimile device 1 and in the normal outgoing call operation, the input destination phone number is compared with the phone number in the pre-registered call permission dial file, and based on the comparison result, The call stop or line disconnection is forcibly executed, and the operator is clearly notified of the execution details. As a result, it is possible to prevent facsimile transmissions to the wrong destination due to operator input errors during the call origination stage, and it is possible to avoid situations where important documents are sent to a third party.
The security function of the facsimile device 1 is improved.

(Effect) According to the invention set forth in claim 1, when the destination telephone number registered in advance and the destination telephone number specified by the operator are compared and they do not match, a notification to that effect is notified and a message is sent. Since the call is stopped, according to the second aspect of the invention, the operator's call operation is monitored and the telephone number information output to the line is detected, and the detected telephone number information and the If the pre-registered destination phone numbers are compared and they do not match, the line is disconnected and a notification is sent to the effect that the line has been disconnected. It is possible to prevent outgoing calls and improve the security function of the facsimile machine.
