Abstract

PURPOSE:To send the communication content in a short time through a desired line without deterioration by deciding a relay destination or a final destination to be sent next automatically based on a terminal number stored in a storage means. CONSTITUTION:A facsimile equipment 1 reads out a facsimile number 10 of a facsimile equipment 3 stored in the 1st address in a memory and the number 10 is dialed and numbers of the 2nd and succeeding orders are sent to the facsimile equipment 3. The equipment 3 stores numbers 11, 12 and a picture into a memory and after the reception is finished, and makes a call to the number 12 stored in the 1st address. Thus, a picture signal is sent to a facsimile equipment 2 from the facsimile equipment 1 through a desired path, that is, a local line 5, a private line 7 and a local line 6. Since a picture signal or the like is sent through a desired line without manual operation and any hard copy, the communication cost, man-hour and time are saved and the deterioration in the communication content is lowered.

Description

Detailed Description of the Invention (Field of Application in P'N Business) The present invention relates to a communication terminal device connected to two or more types of circuits such as a subscriber telephone line, a private line, and a data network, and a communication terminal device of this type. The present invention relates to communication equipment using terminal devices.

[Conventional technology]

Conventionally, for example, in facsimile communication, when sending a relay message from one place to several places, instead of sending the message directly to the final destination, No. 48 was used, in which the sender gave a relay instruction to a facsimile machine with a relay function. There is a method in which the information is sequentially sent and relayed to the destinations registered in advance on the relayed facsimile.

(Problems to be Solved by the Invention) However, in the conventional example described in NQ, there are problems such as transmission can only be performed between subscriber lines and transmission can only be made to destinations registered in advance. By the way, if you have a leased line, the communication cost will be lower if you use the leased line in the section where the leased line is located. For example, suppose you have a dedicated line between your head office in Tokyo and a branch office in Osaka. At this time, consider sending a fax from a business office near Osaka to a business office near Tokyo. First, send a fax from a business office near Osaka to a branch office in Osaka. The Osaka branch office uses the received hard copy to send image signals to the Tokyo head office via a dedicated line, and the Tokyo head office uses the received hard copies to send image signals to 11 offices in the Tokyo area. This method costs much less than direct fax transmission. However, with this method, the Osaka branch office and the Tokyo head office have to resend the fax, which is cumbersome and time-consuming.Also, the images that have been output to the hard copy have to be reprinted manually, which causes image deterioration. There are problems like this.

The present invention has been made to solve such problems, and provides a communication terminal device that does not require any manpower for relaying and can eliminate image deterioration due to retransmission, and communication equipment using this device. This is the first thing to be said.

a. Storage means for storing communication contents and terminal numbers of relay destinations and final transmission destinations sent from other communication terminals.

b. Terminal number determining means for determining the terminal number of the next relay destination or final transmission destination based on the terminal number stored in the storage means.

C1 A terminal determined by the terminal number determining means, which is obtained by subtracting the terminal number determined by the terminal number determining means from the terminal number stored in the storage means, together with the communication content stored in the storing means. A means of transmitting a number to a communication terminal.

d. A connection end that connects two or more types of lines.

(2) A communication facility characterized in that a plurality of communication terminal devices according to C1) are connected to each other by two or more circuits so that they can communicate with each other.

(Function) With the configurations (1) and (2) above, the communication terminal device automatically determines the next relay destination or final transmission destination, and the communication content can be transmitted via the desired line in a short time. Can be transmitted without deterioration.
