Abstract

PURPOSE:To easily achieve facsimile transmission operation by automatically switching the connection of a telephone line from a telephone terminal to a facsimile part in case a transmission original is set and a facsimile identification signal from the reception side is detected. CONSTITUTION:A line controller 20 is comprised of a frequency detection cir cuit 22 to detect a facsimile identification signal from the reception side, and a microcomputer 24. The reader part 36 of a facsimile part 30 reads a transmis sion original and detects that said original is set in a non-telephone terminal. The microcomputer 24 switches the connection of a telephone line 50 from telephone terminals 41-43 to the facsimile part 30 in case a transmission origi nal is set and a facsimile identification signal is detected. Therefore if only an original is set in the reader part 36, an operator can execute the facsimile transmission near the telephone terminal without need to walk to the facsimile part 30.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a communication system device.

[Prior Art] As a conventional communication system device, one is known in which a plurality of telephone terminals and one facsimile device are connected, and the facsimile device has a built-in line control device.

When performing facsimile communication in such a communication system device, a document is placed on the facsimile device,
Call the other party by dialing from one of the telephone terminals, and then press the facsimile start key to start facsimile communication.

[Problems to be Solved by the Invention] In the conventional device described above, when transmitting a document, the facsimile! In addition to placing a document in J or H and dialing from one of the above telephone terminals to call the other party,
There is a problem in that it is necessary to press a facsimile activation key, making the facsimile transmission operation complicated.

[Means for Solving the Problem] The present invention provides a communication system device in which a plurality of telephone terminals can be connected to a non-telephone terminal having a built-in facsimile unit and a line control device. When a facsimile identification signal is detected from the telephone terminal, the telephone line is automatically switched from the telephone terminal to the facsimile section.

[Function] The present invention provides a communication system device in which a plurality of telephone terminals can be connected to a non-telephone terminal having a built-in facsimile unit and a line control device, in which a transmission document is set and a facsimile identification signal from a receiving side is received. When this is detected, the telephone line is automatically switched from the telephone terminal to the facsimile section, making facsimile transmission operations easy.

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

The non-telephone terminal has a line control section 20 and a facsimile section 30, and can connect a plurality of telephone terminals 41, 42, and 43.
It is made from wheat flour. Of course, the number of telephone terminals can be determined as necessary.

The line control unit 20 includes an incoming call detection circuit 21, a frequency detection circuit 22, a switching circuit 23, and a microcomputer (
24 (hereinafter referred to as a "microcomputer"), and a circuit 25 for detecting polarity reversal.

The frequency detection circuit 22 is an example of facsimile identification signal detection means for detecting a facsimile identification signal from the receiving side.

The facsimile section 30 includes an NCU/modem 31, an operation section 32, a display section 33, a recording section 34, a storage section 35,
It has a reading section 36 and a CPU 37.

The reading unit 36 reads the transmission original and detects that the transmission original is set in a non-telephone terminal, and is an example of transmission original detection means. Also, microcontroller 2
Reference numeral 4 denotes an example of a switching control means for switching the telephone line from the telephone terminal to the facsimile section when a transmission document is set and the facsimile identification signal is detected.

FIG. 3 is a diagram showing an example of the telephone terminal 41 in the above embodiment.

Telephone terminals 42 and 43 are similar to telephone terminal 41.

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

FIG. 2 is a flowchart showing the operation of the above embodiment.

The calling party uses one of the telephone terminals 41 to 43 and presses the outside line key provided therein to capture the outside line (51
, 82), hereinafter, it is assumed that the telephone terminal 41 is used to make a call. When an outside line is acquired, "Gaisen OKJ" is displayed on the display of the telephone terminal 41. After reading the display, the operator picks up the handset and emits a dial tone indicating that the switching circuit 23 is ready to accept dialing signals. Listen and dial (33, S4, SS).

At this time, if the other party is not talking, the busy tone cannot be heard (SS), and the ringback tone, which is the sound calling the other party, is heard from the handset, and the ringback tone detection circuit 22 detects the ringback tone ( 37
).

If there is a ringback tone and the polarity is reversed (SS), the reading unit 36 detects that a transmission original is set in the reading unit 36 (S9), and if no transmission original is set, the normal Make a call (sio).

On the other hand, if a transmission original is set, a timer for a predetermined time is started (Si1), and if the 1 frequency detection circuit 22 detects a facsimile identification signal within this timer time (Si2), the telephone line 50 is connected to the facsimile machine. 30 (S l 3) and performs facsimile communication (
SI 4) When facsimile communication is started, "FAX transmission" is displayed on the telephone terminal 41. The operator reads this and hangs up the phone.

If the facsimile identification signal cannot be detected within the above timer time (S15), the line 50 is disconnected (S1
6).

That is, when the microcomputer 24 receives a signal from the detection circuit 22 indicating that a ringback tone has been detected and a signal indicating that the polarity has been reversed from the circuit 25, the microcomputer 24 sends a signal to the CPU 37 of the facsimile section 30.
A signal indicating the presence or absence of a document to be transmitted is requested from the sender. Upon receiving this request signal, the CPU 37 takes in the document presence/absence signal from the reading section 36 and sends the document presence/absence signal to the microcomputer 24 . When the microcomputer 24 receives the signal from the transmitted original cloth,
The microcomputer 24 starts a timer, and when the microcomputer 24 receives the facsimile identification signal from the frequency detection circuit z2, it operates the switching circuit 23 for switching the telephone line 50 from the telephone terminal 41 to the facsimile section 30.

In the above embodiment, the facsimile activation key is omitted from the telephone terminal, but a single frequency detection circuit 22 is provided in its place.

As described above, when sending a facsimile, the sending operation is simple because there is no need to perform any other key operations on the telephone terminal after dialing the telephone number of the other party. For example, if the facsimile section 30 and the telephone terminals 41 to 43 are located far apart, and a document is set on the reading section 36 of the facsimile section 30, an operator present at the telephone terminal will be able to send a facsimile from a distance. There is no need to go to the facsimile section 30 where the telephone terminal is located, and facsimile transmission can be performed even if the user is near the telephone terminal.

[Effects of the Invention] According to the present invention, in a communication system device in which a plurality of telephone terminals can be connected to a non-telephone terminal having a built-in facsimile unit and a line control device, facsimile transmission operations are easy. .
