BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data terminal device that transmits and receives data via a telephone line.

2. Description of the Related Art In recent years, data terminal devices for transmitting and receiving data via a telephone line have been remarkably popularized and are widely used as terminals for communication between terminals and database searches. In addition, the functions of data terminal devices are becoming more sophisticated, such as the function of automatically dialing some of the other party's telephone numbers and the ability to create and store messages to be sent to the other party in advance and automatically It has come to have the function of sending.

A conventional data terminal device as described above will be described below with reference to the drawings.

FIG. 2 is a block diagram showing the configuration of a conventional data terminal. It should be noted that this figure shows only the portions related to the present invention in order to facilitate the explanation. In FIG. 2, 1 is a connection end with a telephone line, 2 is a dial pulse circuit,
A dial signal is sent by disconnecting the DC loop of the telephone line.

A hybrid circuit 3 serves as an interface with a telephone line.

A modem circuit 4 demodulates the FSK signal received from the telephone line and converts it into data, and at the time of transmission, modulates the transmission data to convert it into an FSK signal and sends it to the telephone line.

Reference numeral 5 denotes a microcomputer, which controls the entire data terminal device, and internally includes an input unit 5a, an output unit 5b, an operation control unit 5c, and an internal storage unit 5d.

A keyboard 6 is used by the operator to input data. 7
Is an external storage device, which stores program data of the microcomputer 5 and data for calculation and control.

In order to send an automatic dial message, station storage areas 7a and 7b to which station numbers are assigned are set inside the external storage device 7, in which a telephone number storage area and a message are stored. It is divided into areas.

The operation of the conventional data terminal device configured as described above will be described below.

First, the operator can operate the keyboard 6 to put the data terminal device in the storage mode and store the telephone number and the message in the station storage areas 7a, 7b ... In the external storage device 7. For example, in the storage area 7a of the station number 1, the telephone number of the other party with whom communication is desired and the command or the like at the start of communication can be stored as a message. It is also possible to store only the telephone number without storing the message.

Next, the operator operates the keyboard 6 to set the data terminal device in the automatic transmission mode and specifies the station number to be automatically transmitted, for example, 1, and the microcomputer 5 uses the input unit 5a and the output unit 5b thereof. hand,
Station number 1 specified from the external storage device 7
First, the data of the telephone number is taken out from the area 7a.

The output unit 5 according to the retrieved telephone number data
The control signal is output from b, the dial pulse circuit 2 is driven, and the dial signal is sent to the telephone line.

When a database or a data terminal device, which is a communication partner, responds, a carrier signal is sent via a telephone line. The modem circuit 4 detects this carrier signal,
The microcomputer 5 is notified that communication is possible.

When the microcomputer 5 becomes communicable, it fetches the message data from the external storage device 7 from the area 7a of the station number 1 which was previously designated. If there is no message data, the automatic transmission mode is canceled at this point. If you have message data,
The output unit 5b outputs the data to the modem circuit 4.

The data is modulated into an FSK signal by the modem circuit 4 and sent to the telephone line via the hybrid circuit 3.

However, in the above configuration, the telephone number and message data are stored as a pair in each station storage area, and only one station number can be specified in one automatic transmission mode. When using to send the same message to the other party, it is necessary to store different telephone numbers and the same message in several station storage areas, which is a lot of effort to store and it is also the same storage area. It was uneconomical because I had to memorize many messages of.

Further, since the message storage area is limited, it is difficult to automatically send a long message to a specific destination.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a data terminal device capable of automatically connecting a plurality of telephone numbers and messages for automatic transmission, and more flexible automatic dial message transmission.

In order to achieve this object, the data terminal device of the present invention comprises:
Data input means for an operator to input data, control means for performing overall control as a data terminal device,
Dial signal transmitting means for transmitting a dial signal to a telephone line by a control signal from the control means, interface circuit means for the telephone line, and demodulating a voice signal received from the telephone line via the interface circuit means, and A modem circuit means for modulating the data to be transmitted into a voice signal and transmitting the voice signal, and a storage means for storing the telephone number and message data input from the data input means are provided, and a plurality of station numbers are stored in the storage means. A station storage area for storing the assigned telephone number and message and a queue storage area for storing the station numbers in the station storage area in the order in which they should be sent are provided, and the other party responds after the automatic transmission mode is entered. From the data input means until the communication becomes possible. By storing the station number data stored in the queue area in sequence, and automatically transmitting the telephone numbers and messages stored in the corresponding station storage areas according to the sequence, a plurality of telephone numbers and Messages can be arbitrarily concatenated and sent.

Description of Embodiments An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a portion related to the present invention of a data terminal device in an embodiment of the present invention.

In FIG. 1, 11 to 16 are 1 to 2 in FIG. 2, respectively.
Since it is the same functional block as 6, the description thereof will be omitted.

An external storage device 17 has an area 17a for storing a telephone number and a message therein, and a plurality of station storage areas (17a-1, 17a-) each having a station number assigned therein.
2, ...).

Reference numeral 17a-1 is a station storage area of station number 1, and 17a-2 is a station storage area of station number 2. The inside of the station storage area is composed of an area for storing a telephone number and an area for storing message data.

A queue storage area 17b stores the station number of the station storage area to be transmitted in the transmission order.

Reference numeral 17b-1 is the top area of the queue storage area 17b, and the contents of the station storage area corresponding to the station number stored in this area will be transmitted in the next step.

17b-2 is the second area, and stores the station number of the station storage area to be transmitted next to the area 17b-1. The same applies to 17b-3.

The operation of the data terminal device configured as described above will be described below.

First, the operator operates the keyboard 16 to set the data terminal device in the storage mode, and the station storage areas 17a-1, 17a-2 in the external storage device 17 ...
Can store phone numbers and messages.

At this time, for example, the storage area 17a-1 for the station number 1 stores only the telephone number of the other party with whom communication is desired, and the storage area 17a-2 for the station number 2 is stored.
Can store only the other party's telephone number and store only the message in the storage area of the station number 3.

Next, the operator operates the keyboard 16 to set the data terminal device in the automatic transmission mode, and first inputs the station number, for example, 1 in the station storage area in which the telephone number of the destination to be automatically transmitted is stored. Then, the station number, for example, 3 in the station storage area storing the message to be transmitted is input. The microcomputer 15 has its input unit 15
a, the queue storage area 17b via the output unit 15b
Station number 1 in area 17b-1 at the beginning of
And the station number 3 is stored in the second area 17b-2.

The automatic sending routine on the software of the microcomputer 15 constantly monitors that data is stored in the queue storage area 17b, and when the data is stored in the queue storage area 17b, the area 17 at the head thereof is stored.
The data is fetched from b-1, and the contents of the station storage area corresponding to the data are fetched.

In this case, since the station number 1 is stored in the leading area, the station storage area 17a-1
Take out the contents of. Station storage area 17a-1
Since only the telephone number is stored in, the microcomputer 15 outputs a control signal from the output unit 15b to drive the dial pulse circuit 12, and sends a dial signal.

Next, the microcomputer 15 waits for the queue 17b-
When the data is fetched from 2, the station number 3 is stored, so that the contents are fetched from the third station storage area. No telephone number is stored in this area, only messages are stored, so there is no need to send a dial signal.

Further, the microcomputer 15 retrieves the data from the queue 17b-3, but since the contents are empty, it is judged that the dial transmission operation is completed, the other party responds to the telephone number transmitted earlier, and the communication becomes possible. Wait for When a carrier signal is sent from the other party and the microcomputer 15 is notified that the modem circuit 14 is in the communicable state, the microcomputer 15 starts the automatic message transmission mode.

First, the microcomputer has a queue storage area 1
Returning to the head of 7b, the data is taken out from the area 17b-1. Since the station number 1 is stored here, the contents are taken out from the first station area, but since only the telephone number is stored in this area and no message is stored, the microcomputer 15 waits. Data is taken out from 17b-2 in the queue storage area. Since the station number 3 is stored in this area, a message is stored when its contents are taken out from the third station storage area. The microcomputer 15 sends this message data to the modem circuit 14.

The modem circuit 14 converts this data into an FSK signal and sends it to the telephone line via the hybrid circuit 13.

Further, when the microcomputer 15 retrieves the data from the queue storage area 17b-3, since nothing is stored, the automatic transmission mode is terminated, and thereafter the normal communication mode is set.

All station numbers input from the time the first station number is input until the time when the telephone number is sent and the communication is enabled are stored in the queue storage area 17b and automatically transmitted.

Therefore, if the station numbers 1 and 3 are designated in the automatic transmission mode, the station storage area 17a-
The message stored in the third station storage area can be sent to the other party whose telephone number is stored in 1.

If the station numbers 2 and 3 are designated, the message stored in the third station storage area can be sent to the destination of the telephone number stored in the station storage area 17a-2.

In this way, it is possible to easily send the same message to a plurality of destinations.

As in the conventional example, a telephone number and a message can be stored in one station storage area and sent out.

Further, the telephone numbers can be stored in the station storage area 17a-1 and the station storage area 17a-2, and long telephone numbers can be connected and transmitted as in the case of a long distance call.

Conversely, it is also possible to concatenate messages and send a long message.

As described above, according to this embodiment, a keyboard, a microcomputer for controlling the entire data terminal device, a dial pulse circuit for sending a dial signal to a telephone line by a control signal from the microcomputer, and a telephone A hybrid circuit that interfaces with a line, a modem circuit that demodulates an FSK signal received from a telephone line through the hybrid circuit, modulates data to be transmitted into an FSK signal and transmits the FSK signal, and inputs from the keyboard An external storage device for storing telephone numbers and message data, and a station storage area for storing a telephone number and a message assigned a plurality of station numbers inside the external storage device, and a station number in the station storage area. Store in order to send A queue storage area is provided to store the station number data input from the keyboard in the queue area between the time the automatic transmission mode is entered and the time the other party responds and communication is possible. However, by automatically sending the telephone numbers and messages stored in the corresponding station storage areas according to the order, a plurality of telephone numbers and messages can be arbitrarily linked and sent.

In addition, the queue storage area becomes available from the beginning of the queue storage area again when sending a message when the microcomputer becomes ready to communicate after sending only the telephone number in the corresponding station storage area when sending a dial. Is checked and the message is sent out. Therefore, when only the telephone number is stored in the station storage area corresponding to the station number 1 and only the message is stored in the station storage area corresponding to the station number 2, the station number 1 and the station number 2 are stored in the queue storage area from the keyboard. Even if the input is made in the order of, or conversely, if the input is made in the order of station number 2 and station number 1, communication is possible after the telephone number in the station storage area corresponding to the station number 1 is sent out correctly. Since the message in the station storage area corresponding to the station number 2 is transmitted after the state comes into effect, when the telephone number and the message are stored in different station storage areas, the user can Station Not need to remember the order in which input when inputting the station number corresponding to the storage area from the keyboard.

If the telephone numbers are stored in two or more different station storage areas, or if the message is stored, the corresponding station numbers are, of course, in the order entered in the queue storage area from the keyboard. Each telephone number and each message are sent.

Although the present embodiment shows the automatic dial device using pulse dialing, a tone dial for sending DTMF may be used.

EFFECTS OF THE INVENTION As described above, the present invention includes a number information storage section and a message storage section in which a plurality of station numbers are allocated in the storage means, and a queue storage area for storing the station numbers in the order in which they should be sent. The station number data input from the data input means are sequentially stored in the queue storage area, and when making a call, the number information is continuously sent out to the telephone line in accordance with this order, and in the communicable state. It is configured to continuously send messages according to this order, and by configuring in this way, if a series of telephone number information for calling one party is divided and stored, With a relatively simple operation, the divided telephone numbers can be linked and sent.

For example, if you have contracts with multiple telephone companies, you must specify one of the multiple telephone companies before the subscriber number, but register these multiple line selection numbers as separate stations. It is possible to add an arbitrary line selection number to the beginning of the subscriber number and send it out by a simple operation such as designating one station number when making a call. Therefore, it becomes unnecessary to manually input the line selection number consisting of a plurality of digits before the subscriber number when making a call.

Moreover, by allowing multiple messages to be sent continuously in succession, if you want to add a common message to be sent to multiple recipients (such as greetings), add the common text to other messages beforehand. By storing the message in the message storage section separately from the above, a common message can be added to the main message by selecting the station number, and the transmission operation is very simple.

As described above, according to the present invention, the line selection number and other numbers such as the international telephone line connection number and the outside line connection number (for example, "0") when calling from the private branch exchange to the public line are the subscriber numbers of the other party. It can be registered as another station, and can send multiple messages arbitrarily in succession, and its practical effect is great.
