Abstract

PURPOSE:To prevent a long conversation on a phone by setting an automatic interrupt time so as to start a timer when speech is started thereby measuring the speech time and terminating the speech through the interrupt of a speech line in excess of an automatic interrupt time. CONSTITUTION:A key 12 is inserted to a key lock switch 11 while a telephone set is hooked on to switch the switch 11 in the ON state. Then an optional automatic interrupt time is registered in the unit of minutes with a predetermined operation from a ten-key 15. When a speech is started and an automatic interrupt time is registered in a RAM 7, a timer in a control circuit 16 is started. When the speech time exceeds the automatic interrupt time registered, the control circuit 16 operates a line interrupt relay 8 to interrupt a speech line and to terminate the speech.

Confirms the off-hook state, the program memory 6
The automatic disconnection process is started based on the program stored in.

The operation of the automatic disconnection process is as follows:
It is checked whether or not the automatic disconnection time is registered in the AM 7 (S20), and if the automatic disconnection time is not registered, the automatic disconnection process is terminated. If the automatic disconnection time is registered in S20, the timer 1 and the timer 2 in the control circuit 16 are activated (S21), and after activating the timer 1 and the timer 2, it is determined whether or not the state is the on-hook state. (S2
2) In the on-hook state, timer 1 and timer 2 are cleared to 0 and timer 1 and timer 2 are stopped (S2
3), end the automatic disconnection process.

Further, in the case of the off-hook state in S22,
The difference between the measured time of timer 2 and the registered automatic disconnection time is 1
It is judged whether it is 0 seconds or less (S24), and if it is 10 seconds or less, a tone is sent to the handset 4 (S25), the timer 2 is cleared to 0 and the timer 2 is stopped (S26). It teaches that it takes about 10 seconds until this operation automatically disconnects.

If the difference between the measured time of the timer 2 and the registered automatic disconnection time is not less than 10 seconds in S24, it is judged whether or not the measured time of the timer 1 is longer than the registered automatic disconnection time ( S27) If it is larger, timer 1 is cleared to 0 and timer 1 is stopped (S28), and the line disconnection relay 8 is operated and the line disconnection relay contact 9 is opened for a time longer than the time considered by the telephone exchange to disconnect the call line. (S29). The telephone exchange disconnects the call line because the direct current circuit of the call line is opened for the time considered as the disconnection time of the call line, and the call is considered to have ended. If the measured time of the timer 1 is not longer than the registered automatic disconnection time in S27, the process returns to S22 and the above operation is repeated.

Since this embodiment operates as described above, when the set automatic disconnection time elapses after the start of the call,
The call line is automatically disconnected, and it becomes impossible to make a call for more than the set automatic disconnection time, which makes it possible to prevent long calls. In this embodiment, when the automatic disconnection time is set and released, the key lock switch 11 is operated by the key 12 so that the setting and the release can be performed. Then, the automatic disconnection time may be set and released. Further, in this embodiment, when the setting and cancellation of the automatic disconnection time are completed, the notification is output from the speaker 13 as voice, but it may be displayed on the telephone body.

In this embodiment, a tone is sent to the handset 4 as a teaching means for teaching that the automatic disconnection time is near, but the tone is output from the speaker 13 or "the automatic disconnection time is 10 seconds before. "Tell me by outputting a voice, or by providing an LED etc. on the main body of the telephone and blinking the LED etc. to tell you that the automatic disconnection time is near," Automatic disconnection time is 10 seconds ago. May be displayed to teach.
