Abstract

PURPOSE:To use a data communication equipment for both telephone calling and data communication in common very conveniently by providing a detecting means which detects between a call from a data terminal and a call from a telephone calling terminal and an operator calling means which generates a bell tone, etc., for calling an operator when the call from the telephone calling terminal is judged. CONSTITUTION:A tonal signal detecting circuit 4 detects a procedure and a responce signal from a called station in GII mode and is connected between a relay 11 and a system control unit 1. Further, a modem and dialer 5 is connected between the terminal A of the relay 1 and system control unit 1 and a signal detecting circuit 6 for a call signal from circuit and a circuit 7 which detects whether a transmitter-receiver 12 is in an off-hook state or not is connected between the circuit 13 and system control unit 1 respectively. Consequently, when the telephone calling terminal originates, the operator calling means calls the operator automatically and when the data terminal originates, receiving operation is carried out automatically without the intervention of any operator.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data communication device for communicating image data, text code data, etc., and particularly to a data communication device having a telephone call function for making telephone calls.

[Prior Art] For example, a facsimile machine that performs image data communication has one manual reception mode and one automatic reception mode.

[Problems to be Solved by the Invention] In the manual reception mode, when there is a call from the other party's device, the device is always in a talking state and data communication cannot be performed automatically. In addition, in the automatic reception mode, if the calling party only had a telephone call function, the call could not be made even if the caller wanted to make a call.

In other words, in both manual and automatic reception modes, the called party could not determine whether the calling party was a data terminal or not.
This was extremely inconvenient when the device was shared for calls and data communications.

[Means for Solving the Problems] The present invention aims to eliminate the drawbacks of the prior art as described above, and includes a detection means for detecting whether a call is made from a data terminal or a telephone terminal; Operator calling means is provided to generate a bell sound or the like to call an operator when a call is made from a telephone terminal.

[Function] With the above configuration, when a call is made from a telephone terminal, it is possible to automatically call an operator using the operator calling means, and when a call is made from a data terminal, it is possible to automatically call an operator via the operator. You can perform reception operations without any trouble.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

Figures 1 to 3 illustrate one embodiment of the present invention.
FIG. 1 shows a block diagram of the control circuit.

In Fig. 1, the symbol l is the system control unit, and this unit is the central control unit.
The system is centered around the PU, and is comprised of a ROM containing programs that drive the system, a RAM that stores control commands, etc., and controls the entire system.

A recording system 2 for recording received contents, a reading system 3, etc. are connected to this unit 1.

Also, what is indicated by numeral 4 is a tonal signal detection circuit, and G
It is connected between the relay 11 and the system control unit 1 to detect the procedure and the called station response signal in the II mode.

Further, a modem/dialer 5 is connected between the A terminal of the relay 11 and the system control unit 1.

The circuit indicated by reference numeral 6 is a circuit for detecting a ring signal from the line, and the circuit indicated by reference numeral 7 is a circuit for detecting whether or not the handset 12 is in the OFF hook state. It is connected.

The system control unit 1 also controls a buzzer 8 for calling an operator, an operation panel 9, an apparatus drive system 10, a ringback tone generation circuit 15, and the like. .

Next, the operation of this embodiment configured as above will be explained with reference to the flowcharts shown in FIGS. 2 and 3.

That is, when the power is turned on, the system control unit 1 performs initialization, switches the relay 11 to the terminal A side, and monitors the state.

Then, in step SL, it is checked whether dialing is to be performed or not, and if dialing is to be performed, the process moves to a dialing routine.

If the dial is not dialed, it is detected in step S2 whether or not there is recording paper, and if there is no recording paper, the process proceeds to a display routine that indicates this.

If there is recording paper, the process advances to step S3, and it is checked whether there is a ring tone from the line.

If there is no ring tone, the above monitoring operation is repeated, but
If there is a ringing tone, the process advances to step S4, an automatic reception routine.

Proceeding to the automatic reception routine, in step S5 shown in FIG. 3, the CPU sets a timer to a predetermined time, for example, 5 seconds, and the timer determines whether or not a CNG (calling tone) has arrived by the tonal signal detection circuit 4. (Steps S6 and S7).

Note that since a data terminal such as a facsimile machine that automatically makes a call outputs CNG, it is possible to recognize that the calling party is a data terminal by detecting CNG.

On the other hand, if CNG is detected in step S6, since the calling party is a facsimile machine, the process proceeds to a receiving routine in step S8.

On the other hand, if the timer times out in step S7, since the calling party is a telephone terminal, the buzzer 8 is turned on in step S9 to notify the operator.

At the same time, the ringback tone generator 15 is activated to notify the calling party via the line 13 that the operator is currently being called. Notification may be made not only by ringback tone but also by voice or the like.

Then, the process proceeds to step SIO, when the operator picks up the handset, the OFF hook detection circuit 7 detects the OFF hook state, and switches the relay 11 to the terminal B side.
and the receiver 12, and then turn off the buzzer 8 and ringback tone generator 15 (step Sll
.

512).

In addition, if the call is made from a telephone terminal but the handset is not picked up due to the absence of an operator or other reasons,
If the calling party disconnects the line, proceed to step S.
At step 13, the polarity reversal of the line is detected, and the buzzer 8 and ring eight tone generator 15 are set to 0FFL, returning to the monitoring state (steps 81 to S3).

In this way, it is possible to automatically distinguish between calls made from a data terminal without generating a ringtone, and calls made from a telephone terminal with a ringtone to notify the operator. There is no need for the operator to have to react to every bell sound.

In the above-described embodiment, if the operator on the called side does not answer, the operator on the calling side will not receive any response from the other party, and in addition, there will be an inconvenience in that the telephone charge will be charged.

In such a case, the called operator may, for example,
If the call is not answered within about 5 seconds, it is recommended to use a voice synthesis IC or the like to announce the operator's absence, or to run a tape like an answering machine to record the caller's business.

[Effects] As is clear from the explanation below, according to the present invention, when a call is made from a telephone terminal, it is possible to automatically call an operator using the operator calling means, and when a call is made from a data terminal, it is possible to automatically call an operator. In the case of a call, receiving operations can be performed automatically without operator intervention.
