DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device for transmitting information via a telephone line, and more particularly to a telephone device for automatically transmitting necessary information to a so-called telephone service or the like.

[0002]

2. Description of the Related Art FIG. 6 shows a configuration of a conventional telephone device 1. The telephone device 1 is connected via a telephone line 2 to a destination that performs a telephone service or the like. A dial number for calling a destination is generated for each digit by a human operating the dial key 3. Alternatively, by depressing the auto dial key 4, a dial number transmission request is made to the dial data storage circuit 5, and a signal representing a dial number of a plurality of digits is generated from among dial numbers registered in advance. . Dial number sending circuit 6
Responds to a signal from the dial key 3 or the dial data storage circuit 5 and sends a signal indicating a dial number to the telephone line 2. After the other party answers such a call via the telephone line 2, the transmission / reception circuit 7 transmits information.

[0003] The function of "auto-dial" realized by the auto-dial key 4 and the dial data storage circuit 5 is widely used in multifunctional telephones and facsimile machines. When the dial number of the destination is registered in the dial data storage circuit 5 in advance, the number of the destination is automatically transmitted to the telephone line 2 simply by pressing one or several auto dial keys 4 or the like. be able to. With this function, the trouble of calling the other party by designating the number of the other party one digit at a time from the dial key 3 can be omitted, dialing mistakes such as stumbling or pressing mistakes can be prevented, and dialing can be performed quickly.

[0004]

The conventional telephone device 1 shown in FIG. 6 can call a destination by an auto-dial function. However, after a line is connected to the destination, a telephone service and various types of answering machines are available. It does not have a function of automatically transmitting a plurality of control signals corresponding to control functions of a telephone or the like in sequence in accordance with the reception timing of the other party.
Control signals required in telephone services, etc.
It is necessary to press the dial key 3 to generate one digit at a time. That is, as shown in FIG. 7, when the calling telephone apparatus 1 calls the other party's telephone service by the auto-dial function, the other party sends a response message such as "~ Center. Come. After the response message has been completed, the other party is ready to receive the control code, so that each of the dial keys 3 is pressed down while checking one by one. At the stage where one service code has been sent, the other party recognizes the signal and sends the next response message. Less than,
The necessary control signals are sequentially transmitted.

As shown in FIG. 7, when a control signal is input by pressing the dial key 3 while checking one by one, if the number of digits of the control signal is large, the input is troublesome, and an error easily occurs. If you enter data while confirming it, it will take a long time and the telephone charge will increase.

In order to solve such a problem, it is conceivable to use a function equivalent to the auto dial function, as shown in FIG. 8, in transmitting the control code. That is, a plurality of blocks of a control code required in a telephone service or the like are assigned to some keys and registered separately for each block. After the automatic dial connection to the other party, the service code, which is a block of control code, is sequentially transmitted by depressing a key to which a block of control code is assigned one after another at the timing of receiving a signal of the other party. In FIG. 8, by depressing the auto dial key, a dial number for calling the telephone service of the other party is automatically transmitted. When the line connection to the other party is established, a response message such as “This is the center. Next, the auto dial key is depressed. In the auto dial key, a block of a control signal corresponding to a service code is registered in the dial data storage circuit 5, similarly to the auto dial key.
When the auto dial key is depressed, the registered service code is automatically sent to the other party. The other party recognizes the service code and generates the next response message. Thereafter, each time the calling side receives the response message, the service code registered in advance in the dial data storage circuit 5 corresponding to the other dial key is automatically depressed by depressing the auto dial key. Send out.

With such a method, it is not necessary to press the dial key 3 digit by digit to transmit the service code, and the number of key operations performed during communication with the other party is reduced.
It is expected that the occurrence of mistakes will also be reduced. However, the operation of sequentially transmitting a plurality of control signals in anticipation of the signal reception timing of the other party must also rely on humans, such as by confirming the end of a response message or the like by a human. When a large number of control codes need to be transmitted, the key must be pressed many times while carefully listening to the response of the other party, and the trouble of all operations is not completely eliminated.

An object of the present invention is to provide a telephone device which can automatically and sequentially transmit a control signal and the like after a line is connected to a destination, thereby saving the trouble of key input during the line connection. is there.

[0011]

FIG. 1 shows an electrical configuration of an embodiment of the present invention. Telephone devices 11 such as multifunctional telephones and facsimile machines
Can communicate with the other party that provides telephone service or the like via the telephone line 12. Calling the other party
This is performed by transmitting a dial number registered in advance in the dial data storage circuit 15 from the signal data transmission circuit 16 to the telephone line 12. A general telephone call and transmission and reception of image data are performed by the transmission and reception circuit 17.

In addition to calling by dialing to the other party, control signals for telephone service and the like are automatically sent out at intervals according to the signal receiving timing of the other party after connection to the other party. A storage circuit 20, a line connection confirmation circuit 21, and a transmission timing detection circuit 22 are provided. Information to be transmitted to the other party via the telephone line 12 is stored in advance in the transmission signal data storage circuit 20 as storage means. A line connection confirmation circuit 21 serving as a connection confirmation means monitors the polarity of the DC voltage applied to the telephone line 12, and confirms that the line has been connected when the polarity is reversed. In a public telephone line, a DC voltage is applied to the telephone line 12, and when the exchange makes a line connection to the other party, the polarity of the DC voltage is inverted. Therefore, the polarity inversion is detected to confirm the line connection. can do. The transmission timing detection circuit 22 as a control means detects the information receivable state of the other party when the silent state continues after the end of the response message from the other party.

Hereinafter, the telephone device 11 shown in FIG.
An operation of automatically performing an operation such as a telephone service will be described. First, one key is assigned as a designating means for each of a plurality of telephone services, and when the key is pressed, a setting is made so that communication for the telephone service is executed. The dial data storage circuit 15 registers the dial number of the other party, and the transmission signal data storage circuit 20 registers a control code to be sent after the line is connected to the other party.
When a plurality of control codes are required, they are separately registered for each block. For example, in an airline's vacancy guidance service, the service code, boarding date, flight number, and number of seats are asked sequentially, so the "service code", "boarding date", "flight name", and "seat" The signal data of "number" is separately registered in advance.

The operation when a key assigned to the vacancy guidance service is depressed to make a service request will be described with reference to FIG. When the key is depressed, the dial number transmission request for the vacancy guidance service is made to the dial data storage circuit 15, as indicated by. From the dial data storage circuit 15,
The dial data is transmitted as shown by, and is automatically transmitted to the telephone line 12 via the signal data transmission circuit 16. The dial signal is dialed by a dial pulse signal (DP) when the telephone line 12 is a rotary dial line, and by a push button signal (PB) when the telephone line 12 is a push-phone line. The dial pulse signal is a pulse signal generated by turning off the contacts when the dial returns to its original position after turning the dial to a predetermined number. The push button signal generates a plurality of sine wave signals in a predetermined combination for each push button.

In general, only a push button signal is accepted as a telephone service control signal. However, the telephone exchange does not operate with the push button signal for the telephone line 12 of the rotary dial line. For this reason, when the telephone line 12 is a rotary dial line, automatic transmission of dial numbers is performed by a dial pulse signal.
After the transmission of the dial signal for the operation of the telephone exchange, the signal data transmission circuit 15 is switched to transmit the push button signal. The push button signal is a combination of signals having a predetermined frequency within the transmission band of the telephone line 12. Even if the telephone line 12 is a rotary dial line, it can be used for communication with the other party after the line connection. The other party normally accepts the control code only by a push button signal.

When the connection from the telephone line 12 to the other party is established by the exchange, the connection is confirmed as shown in FIG. The transmission timing detection circuit 22 detects a response message from the other party, for example, a voice message such as "This is the center. Please give me a service code." As shown, the ready state, which is the information receivable state of the other party, is detected. Next, the transmission timing detection circuit 22 reads out the "service code" from the transmission signal data storage circuit 20 as shown in FIG.
To send to. The detection timing detection circuit 22 sequentially and automatically transmits signal data such as “boarding date”, “flight number”, and “number of seats” as described below. As described above, when one control code has been transmitted, the timing of transmitting the next control code is checked, and the next control code is transmitted. This is repeated until all the registered control codes have been transmitted. After the transmission of all the control codes is completed, the connection of the telephone line 12 is automatically disconnected as necessary, or the operation is shifted to a continuous operation by a human, and a series of automatic operations is completed.

FIGS. 3, 4 and 5 are flowcharts showing the operation of the telephone device 11 shown in FIG. FIG.
This shows the overall operation. When the key assigned to the telephone service is depressed in step a1, the dialed number is read out in step a2, and the call is prepared. In step a3, the read dial number is transmitted to the telephone line 12 as dial data.

Steps a4 and a5 indicated by B
Is an operation for confirming the line connection. FIG. 4 shows the line connection confirmation operation in detail. Step b1 to Step b
In 2, it is determined whether polarity reversal detection is possible. In a general public telephone line or the like, the polarity is inverted after the line is connected. However, in an extension line or a so-called new electric line, the polarity may not be inverted even after the line is connected. Depending on the type of telephone line 12 to which the telephone device 11 is connected, whether polarity reversal detection is possible or not is set in advance by a changeover switch or the like. If the polarity inversion can be detected, the process proceeds to step b3, and it is determined whether the polarity inversion is performed. When the polarity inversion is not detected, the process proceeds to step b4, and it is determined whether a timeout occurs after elapse of, for example, 45 seconds or more. If the timeout does not occur, the process returns to step b3 again.

If the line connection cannot be confirmed by the polarity reversal, the process proceeds to step b5. In step b5, when the other party generates a special signal sound after the rotational connection, the connection signal is detected. If such a signal is not detected, a disconnection signal indicating busy or the like is detected in step b6. If no disconnection signal is detected, a silent state is detected in step b7. Steps b5 to b7 are repeatedly performed for a predetermined time, for example, 45 seconds, and it is determined in step b8 whether a timeout has occurred.

When the line connection is confirmed in step b3, step b5 or step b7, the operation proceeds to step b9. If a time-out has occurred in steps b4 and b8, or if a disconnection signal has been detected in step b6, the process proceeds to step b10, in which a line connection cannot be established.

When the line connection is confirmed at the stage indicated by B, the process proceeds to the data transmission timing confirmation stage of steps a6 and b7 indicated by C. In a normal telephone service, a message such as "Please enter ~" flows by voice, a signal sound such as "beep" is input, or a silent state for several seconds to wait for an input signal continues.

FIG. 5 shows in detail the stage denoted by C. In steps c1 and c2, a special signal sound such as "beep" after the voice message indicating the transmission timing is detected. When such a special signal is not transmitted or detected, the process proceeds to step c3, where a state such as silence that continues for several seconds is detected. Step c2 and step c3 are performed, for example, for 30 seconds, and it is determined in step c4 whether a timeout has occurred. When the data transmission timing is confirmed in step c2 or step c3, the transmission is enabled in step c5. When a timeout occurs in step c4, the transmission is disabled in step c6, and abnormal processing such as disconnection of the line or re-calling is performed.

When the data transmission timing is confirmed in step a6 in FIG. 3, the process proceeds to step a8, where signal data to be transmitted first is transmitted. Next, step a
In step 9 and step a10, the data transmission timing is confirmed, and in step a11, the next signal data is transmitted. Hereinafter, similarly, necessary signal data is transmitted, the last signal data is transmitted in step a12, and the process ends normally in step a13. After the automatic transmission ends normally, the line is disconnected or a continuous operation is performed manually.

Step a5, Step a7, Step a
Step a1 when a timeout occurs at 10 or the like
The process proceeds to step 4, where abnormal processing such as line disconnection and recall processing is performed.

In this embodiment, the telephone device 11 is assigned a telephone service partner for each key. However, when there are many partners, the partner may be designated by a plurality of key input operations. Of course, the operation may be started by a signal input from a control device such as a computer. Telephone device 1
