Description

TECHNICAL FIELD The present invention relates to a data communication device, and more particularly to a data communication device capable of confidential communication.

[Prior Art] Conventionally, a device such as a facsimile device capable of performing confidential communication has been known.

In the conventional confidential communication method, a unique password (ID code, personal identification number, etc.) is set for each communication device, and when a confidential operation is specified by performing a predetermined operation during image transmission,
The original image is transferred to the image memory on the receiving side, and the image information cannot be recorded and output unless the password on the transmitting side is input on the receiving side.

[Problems to be Solved by the Invention] However, in the above-described conventional method, there is a problem that anyone can retrieve data from the data memory as long as the receiving side knows the sender of the data and the password. Therefore, confidential transmission to one individual in a certain department of the company was almost impossible.

Further, in the past, only one password was set for each terminal, so confidential information could be obtained by breaking one password. From this point of view, it is conceivable to interpose a plurality of passwords at different stages of communication processing, but this method has a problem that the operation becomes troublesome. Therefore, a confidential communication system that can handle an arbitrary password with a simple operation is desired.

[Means for Solving the Problems] In order to solve the above problems, in the present invention, a calling key, a destination number preliminarily input corresponding to the calling key, and the partner End information indicating the end of the destination number and storage means for storing a password used for special communication, calling means for making a call, procedure signal sending means for sending a procedure signal for data communication, The information stored in the storage means is sequentially read in response to the input of a call key, and the calling operation by the calling means and the sending of the procedure signal by the procedure signal sending means are controlled according to the read information. And a control unit, wherein the control unit causes the calling unit to make a call to the destination number sequentially read in response to the input of the calling key, and performs a calling process in response to detection of the end information. Let it finish, A configuration is adopted in which the sequentially read password is transmitted to the procedure signal transmitting means as a procedure signal.

[Operation] According to the above configuration, it is possible to switch between the calling and the sending of the password only by sequentially reading the destination number, the termination information of the destination number, and the password from the storage unit.

[Examples] Hereinafter, the present invention will be described in detail based on examples shown in the drawings. Hereinafter, an embodiment relating to a facsimile machine will be exemplified.

FIG. 1 is a block diagram showing the configuration of a facsimile apparatus adopting the present invention. In the figure, reference numeral 10 is a CPU that controls the operation of the entire apparatus, and is composed of a control element such as a microprocessor. The following members are connected to the CPU 10. Reference numeral 20 is a reading unit composed of a CCT sensor or the like, and is used for reading a document image to be transmitted. Also,
Reference numeral 30 is a recording unit composed of a thermal printer or the like, and is used for recording the received original image, recording the original image read by the reading unit 20 at the time of copying operation, and the like.

The communication control unit 40 is composed of a modem, an NCU, and the like, and performs operations such as modulation / demodulation of data transmitted / received to / from a communication line to which the device is connected and line switching.

The operation unit 50 is composed of a display, predetermined switches, keys, etc., and is used for controlling transmission / reception operations.

In this embodiment, the operation unit 50 is provided with a one-touch key.
As is well known, one-touch keys can be used to enter multiple destination telephone numbers.
Used to enter the number with one key press and call the number. A specific telephone number is associated with each of the plurality of one-touch keys and stored. A memory 60 described later is used to store this telephone number.

Further, a memory 60 is connected to the CPU 10. The memory 60 includes a ROM that stores a control program for the CPU 10 and a RAM that stores image data.

Further, in the RAM of the memory 60, telephone numbers are stored in a table format as shown in FIG. This telephone number is a telephone number set for each one-touch key provided on the operation unit 50. Further, in this embodiment, a 4-digit ID code can be set as a password for each telephone number of each destination.

FIG. 3 shows the storage format of the memory 60. The two columns on the left and right of FIG. 3 indicate two nibbles each forming one byte. In FIG. 3, reference numerals P to Q are storage areas for telephone numbers and ID codes assigned to one destination. As illustrated, a record for one destination is identified by a delimiter such as FF (hexadecimal). The telephone number and ID code in one record are identified by the delimiter EE (hexadecimal). Phone number is BCD (2
Evolutionary decimal class) If expressed in a code, one digit can be expressed in one nibble. Also, if the ID code does not use alphabets, etc., one nibble can represent one digit. In the example shown in FIG. 3, "0459717611" is registered as the telephone number and "1234" is registered as the ID code.

The above-mentioned telephone number and ID code are input according to a well-known telephone number registration procedure for a one-touch key. Conventionally, only the telephone number corresponds to the one-touch key, but in the present embodiment, the one-touch key 1
Enter the telephone number and ID code respectively.

Next, the operation of the above configuration will be described with reference to the flowchart of FIG. FIG. 4 shows a part of the control program of the CPU 10 stored in the ROM section of the memory 60 of FIG.

FIG. 4 shows a procedure for transmitting a confidential image in the configuration shown in FIG.
In S10, it is determined whether the confidential key of the operation unit 50 has been pressed. Further, in step S20, it is determined whether or not the destination designation key, which is a one-touch key, has been pressed.

When the above two conditions of steps S10 and S20 are satisfied, the process proceeds to step S30, and the ID shown in FIGS.
Submit the code. The ID code transmission in step S30 is transferred to the receiving side using the information field of the facsimile procedure signal as in the conventional case.

Then, in step S40, the document image read by the reading unit 20 is transmitted to the receiving side by the same procedure as in the conventional case.

According to the above configuration, a predetermined password can be set for each image information to be transmitted. Therefore, when there are recipients of a plurality of messages at the transmission destination, by setting a predetermined password in advance, the confidential image information addressed to an individual can be transmitted.

Further, according to the above-mentioned embodiment, since the password is set in the one-touch key together with the telephone number, a troublesome operation is not required even when performing confidential transmission.

In the above, the configuration is described in which the password is set for each one-touch key, but the password may be input from the keyboard of the operation unit for each communication and transmitted together with the image data. Further, the above password may be used together with the conventional password for each terminal.

Although the embodiment of the facsimile apparatus has been described above, the present invention can be applied to a communication apparatus for image data or character code data of another method, such as Telex. In that case, the output process that is prohibited on the receiving side when the passwords do not match is changed according to the data output method of the device.

[Effect] As is apparent from the above description, according to the present invention, the destination number preliminarily entered in the storage means in correspondence with the calling key, the end information indicating the end of the destination number, and the special The password used for communication is stored, the information stored in the storage means is sequentially read according to the input of the calling key, and the calling operation and the procedure signal by the calling means according to the read information. Controls the sending of procedure signals by the sending means, and when making a call, causes the calling means to make a call to the called party number sequentially read out in response to the input of the calling key, and makes a call processing in response to the detection of the end information. Is adopted and the sequentially read out password is transmitted to the procedure signal sending means by the procedure signal, so that the calling party number, the ending information of the calling party number and the password are sequentially read out from the storing means. Call and It is possible to switch the password transmission and execute it, and it is possible to appropriately execute communication involving password transmission with simple control.In addition, the destination number and password can be set in advance corresponding to the calling key. Since it is stored, it is possible to save the trouble of inputting a password each time a call is made, and the operator's effort when making a call can be saved. Moreover, if the special communication of the present invention is confidential transmission, the image for one communication is saved. A password can be set for each data and sent, and confidentiality can be improved, which is an excellent effect.
