Description

BACKGROUND OF THE INVENTION [0001] Field of the Invention The present invention relates from the center is a mail sender to send mail <br/> how to send mail via a public line. 2. Description of the Related Art Generally, analog lines and facsimile communication networks (F-nets) can be considered as public lines for transmitting mail from a center. In this case, if the line calls the called party, 16 Hz is used on the analog line,
1300 Hz is used in the F-net. Here, as a method of connecting the mail receiving device and the telephone to the same line so that the telephone does not ring when an incoming call is received,
Non-ringing for an F-net (1300 Hz) and pseudo non-ringing for an analog line (16 Hz) are known. Non-ringing is for facsimile only, 1300H
When z is received, only the mail receiving device responds (closes the line), and the telephone does not respond. On the other hand, in the pseudo non-ringing method, when 16 Hz is received, the mail receiving device first responds (closes the line), determines whether the other party is a telephone or a facsimile, and if it determines that it is a facsimile, the facsimile communication If the e-mail receiving device determines that the telephone is
The ringing of the telephone is carried out by sending the call signal of the telephone. In this case, charging starts after the mail receiving device closes the line. [0003] By the way, when a center calls a mail receiving device via a public line and transmits mail, since the ID is mutually confirmed after the line is established, the F-net is It cannot be used because it is packet communication. On the other hand, an analog line can be used because mutual communication after the line is established is free. However, when an analog line is used, charging is started after the mail receiving apparatus receives a call signal of 16 Hz from the line and closes the line, so that there is a problem that a communication fee increases. [0004] The purpose of the present invention is to provide an e-mail transmission method it is possible to reduce the communication fee than if you use only an analog line.

In FIG. 1, a mail sending side center 1 and a mail receiving device 10 are connected via an F-net 2a and an analog line 2b, and transmit image data, code data, and voice data as electronic mail. The F-net 2a and the analog line 2b can be physically constituted by one line. The mail receiving device 10 has an NCU (network control device) 11, a communication control unit 12, a memory 13, a printer 14 and a control unit 15, and the NCU 11 has a telephone (T
EL) 3 is connected. NCU11 is F net 2a
In addition, the F-net 2a and the analog line 2b are connected to the communication control unit 12 at the time of stand-by. That is, the F-net 2a and the analog line 2b are not connected to the telephone 3 during standby. The communication control unit 12 executes a necessary communication protocol with the center 1 and the memory 13 stores
Used to accumulate mail received from. The printer 14 is used to print out the image data (converted into fonts in the case of code data) stored in the memory 13, and stores voice signals in the memory 13 in the case of voice mails, 3 can be reproduced. The control unit 15 controls the entire mail receiving apparatus 10 and performs control as shown in FIG. 2 when receiving a call signal of 1300 Hz from the F-net 2a via the NCU 11. Also, when calling, the NCU 11 closes the analog line 2b and controls to automatically dial the other party. When receiving a call signal of 16 Hz from the analog line 2b via the NCU 11 when receiving a call, the NCU 1
1 closes the analog line 2b, and when it is determined that the other party is a telephone, the mail receiving device 10
By transmitting the call signal of z, the telephone 3 is caused to ring. Next, the operation for receiving a mail from the center 1 will be described with reference to FIG. First, center 1 is F
The mail receiving device 10 is called via the network 2a. In this case, from the F-net 2a to the mail receiving device 10
