Abstract

PURPOSE:To change a switching time optionally in response to the call incoming state by providing a variable count circuit receiving a 1st signal and outputting 2nd and 3rd signals in response to the content and a repetitive incoming call control circuit receiving the 3rd signal and outputting a 4th signal to the variable count circuit or the like. CONSTITUTION:An incoming call detection circuit 1 detecting an incoming call state and a response state of a telephone set in response to an incoming call and outputting a 1st signal representing the content, a variable count circuit 2 outputting 2nd and 3rd signals in response to the content, and a repetitive incoming call control circuit 3 receiving the 3rd signal and outputting a 4th signal to the variable count circuit 2 or the like are provided to the telephone set. When a repetitive incoming call comes in excess of a call setting time at repetitive incoming call within the repetitive incoming call time, the mode changes from the usual mode into the automatic answering mode. Moreover, the user optionally sets the repetitive incoming call time, the switching time and the call setting time at the repetitive incoming call by using an input means. Thus, the changeover to the automatic answering mode is quickly implemented by using the repetitive incoming call.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a telephone with an answering machine function.

Prior Art] Conventionally, telephones with an answering machine function have been set to an answering machine mode and a normal mode. In case of answering mode,
The answering function was activated after a predetermined response time from the arrival time of the incoming call signal. The response time in this answering mode could be set arbitrarily by the person in charge. In the case of the normal mode used as a normal telephone, the telephone automatically switches to the answering mode after a certain switching time has elapsed from the arrival time of the incoming call signal, and the answering function is activated.

[Problems to be Solved by the Invention] The above-mentioned conventional telephones with an answering machine function switch to the answering machine mode after an incoming call signal arrives, and the switching time from when the answering machine function is activated is always constant. If the time period is set longer than necessary, there is a disadvantage that the caller may cancel the call. Also,
This switching time is always constant regardless of the incoming call status, so even in the case of repeated incoming calls where the caller who canceled the call makes the call again, the same response time will be required again, which is a problem. There is.

An object of the present invention is to realize a telephone with an answering machine function that can arbitrarily change the switching time depending on the incoming call status.

[Means for Solving the Problems 1 The telephone with an answering function of the present invention is a telephone with an answering function that is equipped with a telephone that is connected to a central office line in a normal mode, and a recording/playback circuit that is connected to a central office line in an answering mode. In the first step, the incoming call status and the response status of the telephone to the incoming call are detected, and the first part indicates the contents.
an incoming call detection circuit that outputs a signal; a variable counting circuit that receives the first signal and outputs a second signal and a third signal according to the content thereof; and a third signal that the variable counting circuit outputs. a repetitive incoming call control circuit that inputs a fourth signal and outputs a fourth signal to a variable counting circuit; and a repeating call control circuit that performs telephone switching between the telephone, recording and playback circuit, and central office line according to the set mode, and outputs a fourth signal from the variable counting circuit. a mode switching setting circuit that inputs a second signal to be input, and an input means, the repetitive incoming call control circuit stores a predetermined repeated incoming time, and when the third signal is input, the repetitive incoming call control circuit The variable counting circuit stores the switching time and the ring setting time for repeated incoming calls, and outputs the fourth signal for the incoming call in the normal mode.
If the signal content indicates that the incoming call continues for more than the switching time and the telephone will not be taken off-hook,
A second signal is output, and if the signal indicates that the incoming call has been interrupted within the switching time, a third signal is outputted, and a fourth signal is inputted from the repetitive incoming call control circuit. , and the second signal is also output when the state in which the first signal indicates an incoming call exceeds the ring setting time for repeated incoming calls, and the mode switching setting circuit outputs the second signal when the second signal is input. Then, the current mode is recognized as the answering mode, and the station line and the recording/playback circuit are connected, and the repeated incoming call time, switching time, and ring setting time for repeated incoming calls are set according to the input contents to the input means. A telephone with an answering machine feature.

[Function] In the device of the present invention, if the telephone is not off-hook for more than the switching time, or if repeated calls are received within the repeated call reception time and exceed the ring setting time for repeated call reception, the normal mode is switched to the answering mode. Switch. The user can arbitrarily set the above-mentioned repeated call arrival time, switching time, and ring setting time for repeated calls by using an input means, so switching from normal mode to answering mode can be quickly performed using repeated calls. becomes possible.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of a telephone with an answering machine according to the present invention.

This embodiment includes an incoming call detection circuit 1, a variable counting circuit 2, a repetitive incoming call control circuit 3, a mode switching setting circuit 4, and a recording/reproducing circuit 5.
, two switching relays 6, 62 and a telephone 7, and is connected to the central office line L0. This shows a state in which it is connected to an exchange (not shown) via L.

The recording/reproducing circuit 5 and the telephone 7 are connected to a switching relay 6. ,62
and the central office line L respectively. ．． This is connected to L1, and two switching relays switch in answering mode and normal mode, respectively, to connect the central office line L. , L1.

The incoming call detection circuit 1 is connected to the office lines L0, L and the variable counting circuit 2, and detects the incoming call status and the response of the telephone 7. The situation is detected and a signal S1 indicating its contents is output to the variable counting circuit 2. The variable counting circuit 2 stores the switching time and the ring setting time for repeated incoming calls, and switches the mode when the signal S1 indicates that the telephone 7 is off-hook for a period exceeding the switching time. A signal S2 indicating execution is output to the mode switching setting circuit 4, and if it indicates that incoming calls have been stopped within the switching time, a signal S3 indicating this is repeatedly output to the incoming call control circuit. Output to 3. The repetitive incoming call control circuit 3 outputs the signal S4 to the variable counting circuit 3 for a predetermined repeated incoming period after receiving the signal S3. If the signal S1 indicating that a call has been received again is inputted while the signal S4 is being inputted from the repeated call control circuit 3, the variable counting circuit 2 outputs the signal S2 after the ring setting time for the repeated call reception. is output to the mode switching setting circuit 4. The mode switching setting circuit 4 includes two switching relays 6
, 62 to switch between the answering mode and the normal mode. Recording/playback circuit in case of answering machine mode? and station line L. , LI are connected, and in the normal mode, telephone 7 and central office line L are connected.
The two switching relays 6, 62 are switched so that o, L+ are connected, but even in the normal mode, when the variable counting circuit 2 outputs the signal S2, the mode is switched to the answering mode, and the recording/playback is started. Circuit 5 is the central line L o , L
Two switching relays 616■ are switched so that they are connected to +.

The switching time stored in the variable counting circuit 2, the ring setting time for repeated incoming calls, the repeated incoming call period stored in the repeated incoming call control circuit 3, and setting the mode in the mode switching circuit are all utilized by input means (not shown). This can be set by the user.

Next, the operation of this embodiment will be described in the case where the user sets the switching time to 30 seconds, the call setting time for repeated incoming calls to 6 seconds, and the repeated incoming call time to 40 seconds, and uses it in the normal mode.

Station line L. ,L,, the incoming call detection circuit 1 detects the incoming call and sends the signal S indicating the response status described above.
What if we output 1 to variable counting circuit 2? Since it is in the normal mode, the telephone 7 performs a beeping operation. If the called user does not respond using the telephone 7, the variable counting circuit 2 counts the time in this state, and when the counted time exceeds the switching time of 30 seconds, the signal S2 is switched to the mode. If the caller abandons the call within 30 seconds, which is the switching time, and the incoming call is stopped, a signal S3 is output to the repeat incoming call control circuit 3. The repetitive incoming call control circuit 3 outputs the signal S4 to the variable counting circuit 2 for 40 seconds, which is the repeated incoming call time, after the signal S3 is input. When the signal S1 indicating that an incoming call is received while the signal S4 is being input, the variable counting circuit 2 counts the time in this state and calculates the ring setting time of 6 seconds. When it exceeds the limit, a signal S2 is output.

When the mode switching setting circuit 4 receives the signal S2, it switches to the answering mode as described above, and the recording and reproducing circuit 5 switches to the answering mode when the signal S2 is input. , L, are controlled to connect the switching relays 61 and 6■.

In addition, if the caller abandons the call again within the ringing time (6 seconds) at the time of repeated incoming calls, the repeated incoming call time (40 seconds)
After lapse of time, the variable counting circuit 2 and the repetitive incoming call control circuit 3 are in the initial state.

As described above, in this embodiment, if the caller continues to make a call for 30 seconds, or if repeated calls continue for 6 seconds within 40 seconds after the incoming call is interrupted, the answering machine is activated. mode can be switched.

[Effects of the Invention] As explained above, the present invention allows the elapsed time from the arrival of an incoming signal to the switching to the answering mode to be variable when the present invention is used in the normal mode. When receiving repeated calls, it is possible to easily shorten the time from receiving the incoming call signal to entering the answering mode.
