[Industrial application field]

TECHNICAL FIELD The present invention relates to a facsimile machine, and more particularly to a facsimile machine that does not include an image memory.

[Conventional technology]

Known facsimile machines are capable of transmitting image information of documents such as text and photographs to long distances using communication lines.

At present, such facsimile devices have been widely used in the era of office automation, since image communication can be carried out via public telephone lines.

When communicating image information using this widespread facsimile machine, there are cases where it is desired to notify only a specific recipient of the image information. In such a case, the sending side adds a password to the image information and transmits it to the receiving side. When the receiving side receives image information with a password added in this way, it does not immediately record it on paper, but temporarily stores it in the image memory together with the password.

The accumulated image information is printed and recorded on paper only after the recipient who knows the corresponding password inputs the password.

Therefore, only those who know the password can obtain the image information, and this communication method is called confidential communication.

[Problem to be solved by the invention a) By the way, in the conventional confidential communication as mentioned above,
Since the received image information is temporarily stored in the image memory,
There is a problem in that confidential reception cannot be performed in facsimile machines that are not equipped with an image memory.

The present invention has been created in view of these points, and an object of the present invention is to provide a facsimile device that can perform confidential reception without requiring an image memory.

[Means for Solving the Problems] FIG. 1 is a block diagram of the principle of a facsimile apparatus of the present invention.

In the figure, recording means 113 encrypts the input first password and prints it together with the image information.

The processing means 115 performs a restoration process on the manually input compressed image information and outputs it to the recording means 113.

If the first password code is added to the input compressed image information, the switching control means 117 outputs the compressed image information together with the first password code to the recording means 113, and if the first password code is not added. If not, the compressed image information is processed by the processing means 11.
Switch to output to 5.

The reading means 111 reads the document and deciphers the encrypted first password.

The discrimination control means 119 manually inputs the image information read by the reading means 111, and when the first password code is added, the input second password code is added to the read image information. The first password code is compared, and if both password codes are in a predetermined relationship, the image information read by the reading means 111 is output to the processing means 115.

Therefore, overall, if the first password is added to the input compressed image information, it is not restored, but the compressed image information is printed and recorded together with the encrypted first password, and then read. If the first PIN code is added to the image information, it is checked against the input second PIN code, and if both PIN codes are in a predetermined relationship, the read image information is restored and printed. configured to record.

[Operation] When the first password code is added to the input compressed image information, the switching control means 117 outputs the compressed image information together with the first password code to the recording means 113. Recording means 11
3 encrypts the input first password and prints it together with the compressed image information.

If the first password code is not added to the input compressed image information, the switching control means l17 outputs the compressed image information to the processing means 115. The processing means 115 performs restoration processing on the input compressed image information and outputs it to the recording means 113,
Recording means 113 prints and records input image information.

The reading means 111 reads the document and deciphers the encrypted first password.

The discrimination control means 119 manually inputs the image information read by the reading means 111, and when the first password code is added, the input second password code is added to the read image information. The first password code is matched by 1 and 2, and if both password codes are in a predetermined relationship, the image information read by the reading means 111 is output to the processing means 115. The processing means 115 performs restoration processing on the input image information and outputs it to the recording means 113, and the recording means 113 prints and records the input image information.

In the present invention, if the first password code is added to the input compressed image information, the compressed image information is not restored, but is printed and recorded together with the encrypted first password code, and the compressed image information is read. If the first PIN code is added to the image information, it is checked against the input second PIN code, and if the two PIN codes are in a predetermined relationship, the read image information is restored. By printing and recording, confidential reception can be performed without requiring an image memory.
