Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD OF THE INVENTION The present invention relates to an improvement in a facsimile machine having the ability to make calls to different countries using an automatic dialing circuit.

[Technical backlash of the invention and its problems]

With the spread of facsimile machines in recent years, facsimile communications are becoming more common between countries, but recently it has become possible to make calls using an automatic dialing circuit when performing international facsimile communications. A device has been proposed.

However, when making international calls, connection parameters such as dialing signals and standard tone signal formats differ depending on the country. It was only possible to make calls using automatic dialing.

(Object of the Invention) An object of the present invention is to provide a highly functional facsimile device that can reliably make calls using automatic dialing to any country with any connection parameters.

[Summary of the invention]

In order to achieve the above object, the present invention stores telephone number information in a first storage means together with an international code related to this telephone number information, and stores each international code in a second storage means.
- memorize connection parameters corresponding to each country for each code, and when a call operation is performed, read the telephone number specified in this operation from the first storage means and identify its international code; Furthermore, connection parameters corresponding to this international code are read from the second storage means, and predetermined connection control with the partner device is performed based on the connection parameters.

[Embodiments of the invention]

FIG. 1 shows the configuration of a connection control circuit portion of a facsimile machine according to an embodiment of the present invention, and 1 indicates a subscriber line. This circuit includes, in addition to the telephone circuit 2 connected to the subscriber line 1, an automatic dialing circuit 3, and a control signal detection circuit that detects control signals such as busy tones arriving from the other party's device via the subscriber line 1. 4, a random access memory (RAM) 5 for storing telephone number information with an added international code and connection parameters for each country for each international code, and a random access memory (RAM) 5 for inputting telephone number information, calling instructions, etc. The device is equipped with an input section 6 consisting of a push button dial, and a control circuit (CPU) 7.

The control circuit 7 has a microcomputer as a main control section, and as shown in FIG. international code identification means 72 which reads the telephone number information from the RAM 5 and identifies its international code when the call is made, and a connection parameter corresponding to the international code identified by this means is read from the RAM 5, and based on this connection parameter. It has an operating condition setting means 73 for setting the operating conditions of each circuit, and a connection control means 74 for performing predetermined connection control according to the operating conditions set by the operating condition setting means 73.

Because of this configuration, the desired telephone number information is stored in advance in the RAM 5 by the input unit 6 together with the international code related to this telephone number information, and in this state, in order to make a call to the destination device of the above telephone number information. When a speed dial operation is performed on the input section 6, the control circuit 7 first inputs the speed dial number resulting from the speed dial operation in step 3a, and then inputs the RA specified by the speed dial number in step 3b, as shown in FIG.
Telephone number information is read from the storage area of M5, and the international code in this telephone number information is identified.

Then, in step 3G, the connection parameters are read from the storage area of the RAM 5 specified by the international code identification result, and the operating conditions of the circuit are set based on the connection parameters. For example, if the destination country has the same connection parameters as Japan, set the same operating conditions as Japan in the control signal detection circuit 4, and if the destination country has a different busy tone frequency or repetition period than Japan, such as West Germany. In case,
The detection operating conditions of the control signal detection circuit 4 are changed and set for West Germany.

After completing the setting of the operating conditions, the control circuit 7 then proceeds to step 3d, where it outputs the telephone number information read from the RAM 5 in step 3b to the automatic dialing circuit 3 as a call control signal, This allows subscriber line 1
Sends a dial signal. After confirming the completion of transmission of the dial signal in step 3e, the arrival of a busy tone is then monitored in step 3f. This monitoring of the arrival of the busy tone is performed by inputting the detection output of the control signal detection circuit 4. At this time, the detection operating conditions of the control signal detection circuit 4 are set in step 3c for the busy tone sent from the destination country. Therefore, it can be carried out reliably without causing false detection. If the arrival of a busy tone is detected by monitoring the arrival of the busy tone, the process moves to step 31, where the line is disconnected and the standby state is restored. On the other hand, if the pidgey tone does not arrive, it is determined in step 3o whether the connection is completed or not, and if the connection is completed, the image transmission operation is executed in step 3h.

In this embodiment, telephone number information with an international code added and connection parameters corresponding to each international code are stored in the RAM 5, and the international code of the above telephone number information is identified when making a call. Since the connection parameters corresponding to this code are read out from the RAM 5 and the operating conditions of the control signal detection circuit 4 are set based on the connection parameters, busy signals of the other country can be reliably detected. This allows the automatic dialing circuit 3 to reliably connect to any destination country without causing any malfunction.

Note that the present invention is not limited to the above embodiments. For example, in the above embodiment, the connection operating conditions are set as follows:
The case where the detection condition of the busy 1-- signal in the control signal detection circuit is variably set has been described, but in other cases, for example, when it is necessary to vary the signal form of the dial signal, the dial signal sending operating conditions in the automatic dial circuit may be changed. may be set variably. In addition, the types of connection operating conditions to be variably set, the control procedure and content of the control circuit, the circuit configuration, etc. can be modified in various ways without departing from the gist of the present invention.

〔Effect of the invention〕

As detailed above, according to the present invention, telephone number information is stored in the first storage means together with an international code related to this telephone number information, and the second storage means is stored in a manner corresponding to each international code for each country. When a call operation is performed, the telephone number specified in this operation is read from the first storage means to identify the international code, and to correspond to the international code. By reading out the connection parameters from the second storage means and performing predetermined connection control with the other device based on the connection parameters, it is possible to connect to any country with any connection parameters. It is possible to provide a highly functional facsimile device that can reliably make calls by automatic dialing.
