Reference numeral 9 denotes an operation unit, 10 denotes a display unit for displaying a set time of the timer unit 8 and the like, and 11 denotes an indicator lamp which lights when the incoming call detection unit 5 detects a call signal.

(Operation) Next, the operation will be described.

When it is desired to prevent the telephone bell from ringing at night, for example, the time of the timer section 8 is set by the operation section 9 so as to be in the operating state from 11:00 pm to 6:00 am and to be in the non-operating state at other times. Set. The set time can be confirmed on the display unit 10.

In the operating state, the connection section 6 is open, and the telephone line 1 and the telephone 2 are disconnected. In this state, telephone line 1
Is received by the incoming call detection unit 5. Then, the central processing unit 4 turns on the display lamp 11 to visually notify the incoming call. Therefore, even if a call is received during sleep, the indicator light 11 is turned on and no sound is emitted, so that it does not hinder sleep. Also, when a family was awake,
The arrival of a telephone call can be detected without the occurrence of the lighting of the indicator light 11.

When the arrival of the telephone is detected by the lighting of the indicator light 11,
As usual, when the telephone receiver of the telephone 2 is picked up, the response detection unit 7 detects this and the central processing unit 4 closes the connection unit 6 by the detection of the response detection unit 7. Then, a communication path is formed between the telephone 2 and the telephone line 1 that have already been off-hook, and the telephone is connected, and a call can be made.

When it is desired to make a telephone call in the operating state, simply lift the handset, and the response detection unit 7 detects this.
After that, if a dial operation is performed thereafter, a desired party can be called.

In the non-operation state, the connection unit 6 is closed, and when a call signal arrives from the telephone line 1, the call signal is transmitted directly to the telephone 2 via the connection unit 6, and the bell of the telephone 2 rings.
Therefore, if the user goes off-hook accordingly, the call can be made.

In the non-operation state, whether or not to activate the indicator light 11 by the detection of the incoming call detection unit 5 is a design matter,
By operating the indicator light 11, it is also possible to use for the deaf.

Thus, the switching device 3 automatically switches between the operating state and the non-operating state by the operation of the timer unit 8, so that there is no problem such as forgetting to switch.

(Effects) In recent years, the living environment has become even more nighttime, and with that, telephone calls at midnight have been frequently performed. For this reason, the problem that the user is woken up by telephone when he / she thinks he / she has fallen asleep, or that he / she comes to bed early to get out early has become remarkable. So when he didn't want to answer the phone, he turned down the bell volume and unplugged the phone cord from the phone line. However, with these measures, if you do not forget to turn them back in the morning, it will hinder future communication, and there will be a problem that you will not be able to receive calls even if other family members are awake.

However, the present invention provides a connection unit 6 provided between the telephone line 1 and the telephone 2, a timer unit 8 for switching the connection 6 between an open time and a closed state according to a set time, A response detector 7 for detecting off-hook,
