Abstract

PURPOSE:To allow a prescribed recipient to surely receive a document by allowing communication only when a personal identification number corresponding to an added personal identification number is inputted when a destination terminal equipment receives a call. CONSTITUTION:When a caller sends a call to a called terminal equipment by adding a prescribed personal identification number, the called party receives a CSS (session start command), and when the personal identification number is set, a personal identification number input request is displayed on an LCD 3 to await the input of the personal identification number for a specified time. When the personal identification number is entered from a key group 4 within the specified time, the entered number and the number sent from the caller are collated, and only when they are coincident, an RSSP is sent to continue the communication.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication system for outputting information onto recording paper in a destination terminal device such as a facsimile machine.

[Prior Art] Conventionally, facsimile machines have been widely used because they allow documents to be sent with simple operations.

Conventional facsimile machines that print on paper at the same time they are received are usually operated automatically and unattended, so even if a highly confidential document is sent, it is difficult to confirm whether the intended recipient has received it or not. It is not possible for the sender to confirm, nor is it possible to confirm that no one other than the intended recipient has received the message.

By the way, in order to compensate for the drawbacks of the above-mentioned devices, there is a method in which the terminal device is equipped with a storage device such as a disk, the received document is stored in this storage device, and after receiving the document, the password is inputted and the stored contents are retrieved. has traditionally been adopted.

[Problems to be Solved by the Invention] However, according to the above-mentioned conventional method, there is a problem in that a new storage device for storing received documents must be added.

Also, even if you tell the recipient to be in front of the terminal device because you are about to send it over the phone,
There is also a problem in that it is not possible to reliably check whether the recipient is present at the terminal device during actual reception.

An object of the present invention is to provide a communication method that allows a predetermined recipient to reliably receive a received document without adding a storage device for storing the received document.

[Means for Solving the Problems] The present invention makes a call to a predetermined destination terminal with a predetermined PIN number attached, and when the call is received at the destination terminal, communication is started only when a PIN code corresponding to the above PIN number is input. This allows for

[Operation] The present invention allows communication only when a predetermined PIN number is added and a call is made to a predetermined destination terminal, and a PIN code corresponding to the above PIN number is input when the call is received at the destination terminal. , a predetermined recipient can reliably receive a received document without adding a storage device for storing the received document.

[Example] FIG. 1 is a block diagram showing one embodiment of the present invention.

This embodiment uses the MPUI that controls the entire device and the M6
It has a CCU (line control unit) 2 connected to the computer, an LCD 3 which is an example of a display device, a group of keys 4, and a RAM 5.

MPUI is an example of a means for allowing communication only when the calling party sends a call with a predetermined PIN number added and a PIN corresponding to the PIN number is input when the caller receives the call.

FIG. 3 is a front view showing an example of the LCD 3 and key group 4 in the above embodiment.

The key group 4 includes an entry key 7, a start key 8, and a numeric keypad.

Next, the operation of the above embodiment will be explained.

FIG. 3 is a flowchart showing the operation on the receiving side in the above embodiment.

First, when a calling party adds a predetermined PIN number and makes a call to a receiving terminal, the receiving party receives the C35 (session start command), refers to the extended address of the C5S, and enters the PIN code. is set (S2).

If a password has not been set, R55P (Session Start Response) is sent (S3) and communication continues in the same way as a normal facsimile terminal device.

On the other hand, if a PIN has been set in S2, a PIN input request will be displayed on the LCD 3 (54) and the PIN will be on standby for a specified period of time (for example, 60 seconds) (S6).
).

If the PIN number is entered from the key group 4 within the specified time, the input PIN number will be checked against the PIN number sent from the sender (S7), and only if there is a match will the R55 be released. and continue communication.

On the other hand, in S7, if the password entered from key group 4 and the password sent from the sending side do not match, R55N is transmitted and subsequent communication is rejected (s
a).

As mentioned above, if the sender does not enter the same PIN that was added at the time of the call, further communication will be prohibited, and the call will be sent only after confirming that the recipient exists on the receiving terminal. Continue communication on the side. Therefore, a predetermined recipient can reliably receive a received document without adding a storage device for storing the received document.

In the above embodiment, even when communicating with the same recipient, a different PIN is set for each communication, and a call is made to the receiving side with a different PIN added. Alternatively, the same password may be used. In this case, the display on the LCD 3 in S4 may display the name of the recipient.

In addition, in the above embodiment, the password added by the calling party is set to match the password entered by the receiving party, but instead of this, several checks are incorporated so that the transmitting party can The method of checking may be specified using C8S. In this case, in order to select the check method, it is necessary to add one more step from 34 to S7. Also, instead of setting the PIN number added on the calling side and the PIN number entered on the receiving side to be the same, there is a correspondence relationship between the two PIN numbers, and if there is a correspondence, communication is allowed. Good too.

Furthermore, when transmitting R55N (S8), it is possible to distinguish whether R35N was transmitted because the specified time has elapsed or whether R55N was transmitted because the verification (S7) did not match. If the information is sent, the distinction can be displayed on the sending terminal, which is convenient for the operator of the sending terminal.

[Effects of the Invention] According to the present invention, a predetermined recipient can reliably receive a received document without adding a storage device for storing the received document.
