Abstract

PURPOSE:To enable an automatic calling even when a callee station is a manual receiving system by executing a previously prepared communication through a voice after a line is connected to the callee station by an automatic calling, and shifting to an ordinary communication procedure after the callee station recognizes said communication. CONSTITUTION:The operator at a calling side inputs previously the contents of the communication to a voice storing circuit 32 through a voice input circuit 31. When the callee side is anticipated to be the manual receiving system, the automatic calling, such that the previously set subscriber number of the callee side is automatically dialed, by pushing down a communication switch 8, while a voice sending instruction switch 7 is kept at a connected state. When the callee side understands the voice communication and pushes down the own communication switch, a callee station identifying signal CED is sent to the calling station. When the callee station identifying signal detection circuit 5 of the calling station detects the callee station identifying signal CED and makes a detection signal DET to be a high level, a control part 6 makes a control signal CONT for a switch circuit 2 to be a low level, and the switch circuit 2 connects a transmission circuit 4 to a hybrid coil l. The future communication procedure is executed by the transmission circuit 4 according to the control of the control part 6.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine, and more particularly to a facsimile machine having an automatic calling capability.

[Conventional technology]

Conventionally, in this type of facsimile machine, if the called party is manually receiving the call, the user manually makes a call, confirms the call with the called party by voice, and then presses a communication switch to initiate communication.

[Problem that the invention seeks to solve]

With the above-mentioned conventional facsimile machine, if the called party receives the message manually, the operator on the calling party makes a manual call, confirms the call with the called party, and then sends the facsimile. Although the device is capable of making automatic calls, there is a problem in that it cannot make automatic calls.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile machine that can automatically make a call even when the called party receives the call manually.

[Means for solving problems]

The facsimile apparatus of the present invention includes an audio sending circuit that removes the 2]00H2 component from a pre-input audio re-signal and sends it out;
a transmitting circuit that sends out a control signal and an image signal for a communication control procedure; a switching circuit that switches and connects the audio output path and the transmitting circuit to a line; and a called station identification signal of 2100+-12 from the called station. a called station identification signal detection circuit that detects the
When there is an instruction to perform voice communication in advance before automatic calling, the voice output path is connected to the line, and when the called station identification signal is detected, the transmitting circuit is connected to the line. and a control section that controls the switching circuit.

1' Embodiments] Next, five embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

As shown in FIG. 1, the line 9 is connected to the terminals ]1 and ]2 of the hybrid coil 1, and the
One terminal 13 of the coil on the device side is connected to a 21-00 Hz removal circuit 31 and an audio storage circuit 3 via a switching circuit 2.
2. It is selectively connected to an audio output circuit 3 comprising an audio input circuit 33 or a transmission circuit 4 that outputs control signals and image signals for communication control procedures.

The other terminal 14 on the device side of the hybrid coil 1 is connected to a called station identification signal detection circuit 5 that detects a called station identification signal CED of 2100H2 from the called station, which notifies that the called station is a facsimile terminal. connected to.

The control section 6 receives signals from the voice transmission instruction switch 7, the communication switch 8, and the called station identification signal detection circuit 5, and performs switching control of the switching circuit 2 and control of the transmission circuit 4.

In FIG. 1, the operator on the calling side has previously entered the voice input circuit 3.
1 to the following communication contents are input into the audio storage circuit 32. In other words, °"This is ○○ Co., Ltd. First of all, I will send you a manuscript by fax, so please connect me to extension number △△△△ or XXXX." Or, °゛This is ○○ Co., Ltd. I'm about to send you a document by fax, so please press the fax communication switch 6゛Then, if the called party 17111 is expected to receive it manually, the voice transmission will be sent. When the communication switch 8 is pressed with the instruction switch and V-chia in contact, an automatic call is made by automatically dialing the preset telephone number of the called party.
2 FIG. 2 is a timing diagram for explaining the operation of the embodiment shown in FIG. 1. The operation of the embodiment shown in FIG. 1 will be explained below with reference to FIG. 2.

When the communication switch 8 is pressed on the called side, a calling signal CAL in the form of a dial pulse or MP multiplication signal is sent out, and the called side is connected to the line 9 via the telephone exchange. Since the audio output instruction switch 7 is closed, the control signal CONT from the control unit 6 to the switching circuit 2 is at a high level, and the switching circuit 2 connects the audio circuit 3 to the hybrid coil 1. .

Therefore, the audio data previously stored in the audio storage circuit 32 becomes an audio signal OC from which the 2100 Hz component is removed by the 2100 Hz removal circuit 31, and is sent to the line 9 through the hybrid coil 1. Here, 2100H
The purpose of removing the z component is to prevent false detection of the called station identification signal CED of 00 Hz, which notifies the calling station that the called station is a facsimile terminal [2].

When the called side understands the voice communication and presses its own communication switch, the called station identification signal CED is sent to the calling station.

The called station identification signal detection circuit 5 of the calling station detects the called station identification signal C.
When ED is detected and the detection signal DE' is set to high level 1, the control section 6 sets the control signal C0NT to the switching circuit 2 to a low level, and the switching circuit 2 connects the transmitting circuit 4 to the hybrid coil 1.

The subsequent communication procedure is performed by the transmitting circuit 4 under the control of the control section 6 in accordance with CCITT Recommendation 30.

〔Effect of the invention〕

As explained above, in the facsimile device of the present invention, an instruction to perform voice communication is inputted before executing the communication procedure.
After making an automatic call and establishing a line connection with the called station, we perform voice communication prepared in advance, and after the called station understands the notification, we proceed to the normal communication procedure, allowing the called station to manually receive the call. This has the advantage that automatic calls can be made even in the case of
