DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus, and more particularly, to a facsimile apparatus having a memory for storing image data.

[0002]

2. Description of the Related Art Conventionally, in a facsimile apparatus of this type, a confidential function is required on each of a transmitter and a receiver. Also, before starting communication, the transmitter performs confidential communication designation and password input, and after completing the settings, connects to the receiver via a line and performs confidential communication for each document management. In this case, the security of the document from the transmitter was secured.

[0003]

The above-described conventional facsimile apparatus cannot extract the document stored in the memory unless the password number set on the transmitter side is input. For this reason, it has always been necessary to confirm the password number between the sender and the receiver for each communication. Further, a confidential function is required for each of the transmitter and the receiver, and confidential communication cannot be performed from a transmitter having no confidential function. Also, even when the transmitter has a confidential function and specifies confidentiality, since the memory area of the receiver can be occupied by a single operator, the probability that the memory area of the memory becomes full is high and confidential communication is not possible. There was a problem that I could not do it.

[0004]

Facsimile apparatus of the present invention, in order to solve the problem] is provided with a memory unit for storing image data, a recognition unit for recognizing PB tones from the transmitter side and a receiver for performing a procedure for facsimile communication Facsimile machine,
In the procedure of the facsimile reception, identifies the ID code detected by the recognition unit, advance the ID code
An identification unit that converts the password into a password registered in accordance with a password, and the ID code is registered in the identification unit in advance.
The memory allocated for each password unit
Corresponds to the password in a plurality of memory areas in the department
It is characterized by having the a that control section to accumulate the image data in the memory area. In addition, the aforementioned facsimile
The device has an input procedure for the password
If the password is registered in the identification unit,
Reception assigned to the handler and stored in the memory unit
Having means for printing out the document.

[0005]

Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is a sequence diagram showing a communication procedure of the embodiment.

[0006] A transmitter 1 and a receiver 2 are connected by a line 3. The line 3 is requested by the line connection request from the transmitter 1.
Makes a call to the receiver 3 by a ringer (call signal), and the line controller 4 in the receiver 2 detects this ringer. After the transmitter 1 and the receiver 2 are connected to each other by ringer detection, the receiver 2 requests the transmitter 1 via the line controller 4 and the line 3 to input a mail number from the voice synthesizer 5. Is notified by a message using the voice synthesizing unit 5, a state of waiting for an answer tone from the transmitter 1 side, timeout occurs if the answer tone is not returned within a specified time, and CED (T3 of CCITT recommendation).
(Defined as 0.)

The transmitter 1 sends the ID code of the destination of the document according to the content of the voice message within a specified time using a PB tone and notifies the receiver 2 via the line 3. The receiver 2 having received the notification by the ID code recognizes the frequency component in the recognition unit 6 via the internal line control unit 4, converts the analog signal of the PB tone into a digital signal, and then sends the digital signal to the identification unit 7. The signaled ID code is transmitted.

In the identification section 7, it is necessary that an ID code required for data input and a password number required for data output be registered in advance by an operator, and a password corresponding to the ID code is required. The relationship of the identification unit 7
It is assumed that the information is clearly input.

[0009] It is determined whether the ID code output from the recognition unit 6 is a registered ID code in the identification unit 7, and if the ID code is a registered ID code, it is converted into a password corresponding to the ID code. , And notifies the control unit 8 of a data write request and a password. The control unit 8 manages the memory space of the memory unit 9 by dividing the memory space into a plurality of memory areas, and is managed so that each memory area is assigned to each password.

Upon receiving the data write request and the notification of the password, the control unit 8 selects one of the memory areas and, at the same time, performs a facsimile communication procedure by the receiving unit 10 and then performs data write control to perform the data write control. Image data is stored in the area. After the image data is stored, protection of the image data and management of the location of the image data are also performed.

When the data storage is completed normally, the control unit 8 notifies the identification unit 7 of completion, and the identification unit 7 uses the display function inside the receiver 2 to display the ID code in which the data is stored. The presence / absence of image data is displayed, and the presence of the image data stored in the corresponding memory area of the operator on the receiving side is called to the substitute telephone, and the voice synthesis unit 5
Is notified by using a voice message. Memory unit 9
The size of each memory area inside is allocated evenly to prevent the exclusive use of the memory area,
Ensure memory areas for multiple operators.

Next, when outputting the received image data, the operator inputs a password to the identification unit 7 through an operation from an external operation panel, and checks whether the password is a registered password. Will be If the password is a registered password based on the collation result, the data read request and the password are notified to the control unit 8. Upon receiving the data read request and the password notification, the control unit 8 performs data read control on the memory area corresponding to the password,
Prints out the image data of the document as a hard copy.

[0013]

As described above, according to the present invention, the confidential communication designation is notified to the receiver using the PB tone of the transmitter, and the ID code required for data input and the password required for data output are provided. And confidential communication are realized regardless of the compatibility of the confidential function on the transmitter side and the presence or absence of the function by providing multiple memory areas that divide the memory space equally By using the divided numbers, the common ID code can be disclosed to all operators on the transmission side, and confidentiality can be maintained for each operator on the receiver side.
