However, in the first proxy response method described above, the absence transfer registration to another telephone must be registered every time the user leaves the desk, and the absence transfer registration must be canceled each time he / she returns. However, there is a problem that the operation is very complicated. Further, in the second method, when the space is divided by a partition such as a recent office space, it is often difficult to know whether or not there is an answering staff near the incoming telephone. In this case, For the first time, I noticed the absence of the answering staff because the ringing tone of the telephone was ringing for a long time, and the proxy answering staff rushed to the place of the telephone that received the call at that point, which could cause the caller to wait for a long time. .

The present invention has been made in view of the above circumstances. When an incoming call is received by a telephone whose answering staff is absent, it is detected that the answering staff is absent and a special operation is performed. It is an object of the present invention to provide an incoming call transfer device that can transfer a call to another nearby telephone without waiting the caller for a long time.

Further, in the incoming call transfer device according to the present embodiment, the detection means 101 to 10n excluding the human body detection sensors S1 to Sn and the control portion constitute a control means.

Next, the operation of the incoming call transfer device of the present embodiment configured as described above will be described. In order to simplify the description, the human body detection sensor S1 of the detection unit 101 in the area AR1 in which the telephone 1 of the telephones 1 to n is installed detects the absence of response personnel in the area AR1. And human body detection sensors S2 to S in areas AR2 to ARn where other telephones 2 to n are installed.
A case will be described in which n detects the presence of response personnel in the areas AR2 ,.

As described above, since there is no responder in the area AR1, the human body detection sensor S1 cannot detect human heat, the contact P1 is opened, and the other areas AR2 to AR2.
Since there is a responder in Rn, the heat is detected by the human body detection sensors S2 to Sn and the contacts P2 to Pn are closed. Since the contact P1 of the detection unit 101 is opened, the auxiliary relay X1 is deenergized, the contact X1a is opened, and AN
The first input end of the D circuit 11 is at the “L” level and the output end thereof is also at the “L” level, so that the dial signal transmission device 401 is not driven.

Further, the contact points P2 of the detecting portions 102 to 10n
Since Pn is closed, all the auxiliary relays X2 to Xn are energized, their contacts X2a to X2n are closed, and the "H" level signal is sent through the line 201 to the AND circuit 22 to.
The second input of n2 is reached. Further, by opening the contact X1a, the first input end of the OR circuit 501 becomes “L”.
When the level and the contact X2a are closed, the OR circuit 5
The second input terminal of 01 becomes "H" level, and therefore
The output terminal of the OR circuit 501 becomes the “H” level.

On the other hand, since the contact Xn-1a (not shown in FIG. 1) and the contact Xna are both closed, the first and second input terminals of the OR circuit 50n are both at the "H" level. Therefore, the output terminal of the OR circuit 50n also becomes the “H” level.
Therefore, the first and second input terminals of the NOR circuit 601 are both at "H" level, the output terminal of the NOR circuit 601 is at "L" level, and as a result, the second input terminal of the AND circuit 701 is at "L" level. It becomes a level. As a result, the guide sound transmission device 801 is not driven.

In such a state, that is, when there is no responder in the area AR1 in which the telephone 1 is installed, the telephone 2 to
When there is a response person in the area AR2, ... In which n is installed, when the telephone 1 in the area AR1 receives a call, the switching circuit S11 is turned on, the contact of the switching circuit S12 becomes the A side, and this incoming signal is the switching circuit. AN through S11, S12 and the buffer circuit B1
At the same time when the voltage is input to the second input terminals of the D circuits 11, 21, ...
An “H” level signal is input to the input end and the guide sound transmission device 901.

When an "H" level signal is applied to the guide sound transmitting device 901, the guide sound transmitting device 901 generates a guide sound. This guide sound is for notifying the caller that the call is being transferred to the other telephones 2 to n other than the telephone 1, and as described above, for example, "I am not in my seat, Forward to someone. " The output signal from the guide sound transmission device 901 is input to the control switching circuit S0, and accordingly,
Guide sound transmission device 901 in control switching circuit S0
The switch corresponding to is turned on, and further reaches the switching circuits S12 to Sn2 from the control switching circuit S0 through the buffer circuits B11 to B1n, and switches these contacts to the B side.

As a result, the guide sound generated from the guide sound transmission device 901 is transmitted from the closed contact X1b to the originating telephone set via the private branch exchange (PBX) not shown, and the guide sound is generated. When is finished, the switching circuit S11 is once turned off, the telephone 1 is put on hold, and the transfer preparation is completed.

When the telephone 1 receives a call, the contact X1a is at the "L" level, so the output end of the NOR circuit 210 becomes the "H" level and the first input end of the AND circuit 22 becomes the "H" level. Become. Further, since the contact X2a is closed and is at the "H" level, the second input terminal of the AND circuit 22 is at the "H" level, and therefore the AND
The output end of the circuit 22 becomes "H" level. This allows
The first input terminal of the AND circuit 21 is at the “H” level, and the second input terminal of the AND circuit 21 is also at the “H” level because the switching circuit S11 is turned on at this time by the incoming signal to the telephone set 1. The output of the AND circuit 21 is “H”.

As a result, due to the "H" level output of the AND circuit 21, the dial signal transmitting device 402 receives the incoming call when the switching circuit S11 is once turned off and then turned on again, that is, as shown in FIG. At t1 seconds after the signal is input, the dial signal transmission device 402 starts transmitting the same tone as the dial tone of the extension number of the telephone set 2. When the dial signal transmitting device 402 generates a dial sound, the dial sound is input to the control switching circuit S0, the switch corresponding to the dial signal transmitting device 402 in the control switching circuit S0 is turned on, and the above-mentioned guidance is given first. Since the switching circuits S12 to Sn2 are switched to the B side by the output signal from the sound transmitting device 901, the dial sound for calling the telephone 2 from the dial signal transmitting device 402 is sent to the PBX.

As a result, the line received by the telephone set 1 via the PBX is switched to the line of the telephone set 2, and the PBX calls the telephone set 2. The human body detection sensor S2 in the area AR2 in which the telephone 2 is installed detects that there is a response person M (FIG. 2) in the area AR2, and accordingly, the contact X2b of the auxiliary relay X2. Is released,
Since the contact X2c is closed, the call signal from the PBX is sent to the telephone 2 via the contact X2c,
The response person M in the area AR2 answers the telephone 2 to complete the transfer. Then, when the generation of the dial tone generated from the dial signal transmission device 402 is stopped, that is,
As shown in the time chart of FIG. 3, time (t1 + t
2) After a second, the switching circuit 11 is turned off and the transfer is completed. Then, when there is no responder in the area AR2 in which the telephone 2 is installed, the same operation as described above is repeated, and another telephone 3 (not shown in FIG. 1) to a telephone. The transfer operation to n is performed.

When there is no responder in any of the areas AR1 to ARn, the contacts P1 to Pn are both opened, the auxiliary relays X1 to Xn are deenergized, and the contact X1a.
To Xna are opened, and the output terminals of the OR circuits 501 and 50n are both at the “L” level. Therefore, both input terminals of the NOR circuit 601 become the “L” level, and the NOR circuit 6
The output terminal of 01 becomes the “H” level, and the second input terminal of the AND circuit 701 becomes the “H” level.

Therefore, the guide sound transmitting device 801 is driven, and a guide sound from the guide sound transmitting device 801 such as, for example, "Please re-try because there are no seats at present" is sent to the control switching circuit S0. The control switching circuit S to which the output signal of the guide sound is input.
At 0, the switch corresponding to the guide sound transmission device 801 is turned on, and accordingly, a signal of "H" level is input from the buffer circuit B11 to the switching circuit S12. Then, by switching the contact of the switching circuit S12 to the b side, as described above, for example,
A guide sound such as "all of you are not in the seats at the moment, please try again" is sent to the caller's telephone via the PBX, and the caller's telephone is hooked to disconnect the incoming telephone line.

In the above embodiment, the human body detection sensors S1 to S by pyroelectric sensors are used as means for detecting the human body.
Although the case where n is used has been illustrated, the detection means is not limited to this, and for example, a light emitting means and a light receiving means are arranged in each area AR1 to ARn with a predetermined distance, and whether or not the light receiving means receives light. Human detection may be performed based on the above. Further, ultrasonic waves may be applied to the areas AR1 to ARn to detect whether or not a person is present in the area depending on whether or not the reflected waves are received.

[0030]

As described above, according to the present invention,
When there is an incoming call to a telephone that does not have a response person, the detection means detects that there is no response person, and based on this detection result, the telephone number assigned to the telephone other than the called party is dialed. Since the control means controls the transmission from the transmission means to the exchange, the data can be transferred to another nearby telephone without any special operation or waiting for the transmission source for a long time.
