Abstract

PURPOSE:To attain high probability of connection to an opposite party and to utilize effectively the time so far by sending automatically a redial signal after a prescribed time if the opposite party is busy. CONSTITUTION:A dial is inputted to a control circuit 6 from a key operation section 5, stored in a dial memory circuit 4 and a dial signal is sent from a trunk line circuit 2 to a trunk line 1. If the opposite party of dialing is busy in this case and since the probability of busy state is high by immediate call back, redialing is applied automatically after a prescribed time. The operator uses a key operating section 5 to input the operation of automatic redialing to a telephone terminal device after a prescribed time elapses while the handset hooks on. The control circuit 6 allows a timer circuit 7 to count a prescribed time and allows the trunk line circuit 2 to catch the trunk line 1 automatically and sends the same dial signal again.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a telephone device having a function of automatically redialing again when the other party is busy.

(Prior Art) Fig. 2 shows a conventional telephone device with a dialing function. In the figure, 1 is a central office line of the telephone, and 2 is a central office line circuit for detecting and displaying incoming calls on the central office line, sending out dial signals, etc. , 3 is a communication circuit for making calls to the office line, 4 is a dial memory circuit that stores the previously sent dial number for redialing, and 5 is a dialing, redialing, and other circuit necessary for operating this device. 6 is a control circuit that controls the entire telephone device.

In FIG. 2, the user operates the dial when making a call. The dial is inputted from the key operation section 5 to the control circuit 6, stored in the dial memory circuit 4, and
A dial signal is sent from the office line circuit 2 to the office line l.

If the person dialed at this time is busy, the user must hang up and dial the same person again. In this case, the user inputs a call termination signal from the key operation section 5, and then operates a key for redialing. The control circuit 6 reads the key, sends an end-of-call signal from the office line circuit 2 to the office AL, and then reads out the previously stored dial from the dial memory circuit 4 and sends the dial to the office line circuit. 2 to central office line 1, and the redial operation is completed.

(Problems to be Solved by the Invention) In the above configuration, the redial operation is often performed immediately after the other party is busy, so even if redial is performed, the problem is that the other party is often busy again. there were.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a telephone device that eliminates the drawbacks of the prior art and automatically redials after a certain period of time based on when the other party is ending the call.

(Means for solving the problem) The telephone device of the present invention stores the previously dialed number,
In a telephone device equipped with a redial function that can automatically dial the number with a simple operation,
It is equipped with a timer circuit and a monitor circuit, and automatically performs 9 dialing after a certain period of time by the timer circuit and monitor circuit.

(Example〕 An embodiment of the present invention will be described based on FIG.

In this figure, the same parts as in the conventional example shown in FIG. 2 are given the same numbers, and the explanation thereof will be omitted.

In FIG. 1, 7 is a timer circuit for counting time in order to send out a redial signal after a certain period of time;
Reference numeral 8 is a monitor circuit that allows you to amplify and hear the voice of the other party when dialing without leaving the handset on.

Next, the operation will be explained. First, the user operates the dial when making a call. The dial is input from the key operation section 5 to the control circuit 6 and stored in the dial memory circuit 4, and at the same time, the dial signal is sent from the office line circuit 2 to the office line 1. At this time, the person you dialed is busy, and even if you call back immediately, there is a high probability that the person is busy, so redialing is automatically performed after a certain period of time. With the handset put down, the operator inputs an automatic redial operation into the telephone terminal device from the key operation section 5 after a certain period of time has elapsed. The control circuit 6 causes the timer circuit 7 to count a certain period of time, then automatically captures the office line 1 with the office line circuit 2, and causes the same dial signal to be sent out again. Since the monitor circuit operates to automatically acquire the central office line and send out a redial signal at the same time as the central office line is acquired, the user can hear the operation of this device. Thereafter, when the other party answers, the other party's voice is heard through the monitor circuit, so the user picks up the handset and speaks with the other party through the telephone communication circuit. If the other party is busy, you will have to end the call or redial again.

(Effects of the Invention) According to the present invention, if the other party is busy, it is possible to automatically send a redial signal after a certain period of time, so the probability of connecting to the other party is high and the time until then can be effectively used. There are effects that can be used.

Furthermore, since a redial signal is not sent immediately after the other party is busy, the call loss rate is improved and the central office can operate more efficiently.
