JPS61219251A - Responding ringer device for telephone set - Google Patents

Abstract

PURPOSE:To call for and transfer easily to other telephone set connected to the same telephone line from a telephone set communicating with a line wire by inserting a responding and ringing device between a receptacle for a telephone set and a plug to which the telephone set is connected. CONSTITUTION:When receiving from a line wire through telephone lines L1, L2, this is detected in a voltage change detecting circuit 8, a ring back tone is outputted from a ring back tone transmitting circuit 9 and a speaker 3 is rung. When pressing a holding switch 4 in one responding ringer device A1, a holding voltage change circuit 10 is operated, voltages of the telephone lines L1, L2 are changed, and then, when pressing a calling switch 2, a calling voltage change circuit 11 is operated, and similarly, the voltages of the telephone lines L1, L2 are changed again. The voltage is changed of a voltage change detecting circuit 8 of the other responding ringer device connected to the same telephone lines L1, L2. By the voltage change when a receiver of a telephone set T1 is raised a display lamp on speaking 6 is lighted and by the voltage change when the holding switch 4 is pressed, a holding condition display lamp 5 is lighted.

Description

[Detailed Description of the Invention] [Technical Field] The present invention is an adapter-type adapter that is inserted between a telephone outlet connected to a telephone line and a telephone to enable mutual calls and multifunctionality. This invention relates to a telephone answering device.

[Background technology]

Generally, when one telephone is connected to a telephone line to make a call, multiple telephones T are connected to one external line (office line).
1, T, . . . , as shown in Fig. 3, provide a telephone outlet C for the telephone line L1, L, and insert a plug P into which the telephone T lt TM . This is accomplished by plugging in the . With this method, it is possible to make a call to an outside line from any telephone T1, T, . There is also an incoming call from an outside line, a person picks up the phone T, and makes a call, and the caller's desired party is the phone T.

When it is determined that the person is at a certain location and the call is to be transferred to the telephone T, as shown in FIG.

, A has been proposed in which mutual calls can be made by operating the call switch (2) of the response ringing device A, , A. That is, for example, when the call switch (2) of the answering ringer A is operated on the side of the telephone T, the answering ringer A of the other side is operated.
, a ring tone is generated and it is possible to notify the telephone T, by raising the handset of the telephone T8,
The other party has completed this call. However, although the response ringing devices A, , A shown in FIG. 4 are capable of calling the other party, they do not have other functions and are inconvenient. When making a call, you must keep the handset of telephone T1 in the K position, and there are other requests such as listening to the voice on the telephone loudly through the speaker, or shortening the dialing time of the telephone. However, it has been impossible to achieve these functions when using conventional regular telephones.

[Purpose of the invention]

The present invention is a telephone response ringing device that allows for easy call forwarding without the need for any special construction work, etc. It is an object of the present invention to provide a telephone answering device that has various functions such as a speed dial function in addition to display.

[Disclosure of the invention]

FIG. 1 shows a configuration diagram of an embodiment of the present invention, and FIG. 2 is a 1099-degree diagram of its internal circuit. Telephone outlets C1 and C2 with telephone lines connected to them, L, and telephones T,...
T, is connected to one radio P.

, P. During this period, the response ringing device A, , A of the present invention.

is removably inserted, and is a relay nozzle pA for insertion into the telephone outlet C1, C,
It consists of a circuit section +1) for performing various circuit operations described below, and a relay outlet CA to which the telephone T, T, side I) Pt, PI is attached, and the above-mentioned The circuit section +11 is equipped with a call switch (2), a speaker for ringing (3), a hold switch (4), a hold status indicator lamp (6), a busy indicator lamp (6), etc. .

Thus, in the above embodiment, telephone outlets C, .
Insert the plug PA into C, and the telephone radio P.
, P, was pressed by 0 outlets, and 0 telephone lines were pressed. L,
are connected to telephone outlets C1, C, and telephone T.
1, T, are connected to the telephone plugs P, , P, and between them, the response ringing device A1.1 of the present invention is connected. A is placed in the closet. When there is an incoming call from an outside line via the telephone line Lt*Ll, this is detected by the voltage change detection circuit (8) via the branch connection circuit (7) including the radio PA, and the ring tone sending circuit ( 9) outputs a ringing tone, and a sounding means such as a speaker (3) sounds. In addition, when the hold switch (4) is pressed in one response ringing device A1, the hold voltage change circuit (lO) operates, and the voltage of the telephone line L is changed via the branch connection circuit (7). change. Next, when the call switch (2) is pressed, the call voltage change circuit (11) operates, and the telephone lines L1 and L are connected in the same way as above.
, the voltage changes again. So the same phone line...
In the other zero response ringing device A, which is connected to , the voltage change detection circuit (8) detects the voltage change through the branch connection circuit (7), and detects the voltage change when the handset of the telephone T, is raised. If there is, the busy indicator lamp (6) is lit, and if the voltage change is the same as when the hold switch (4) is pressed, the hold status indicator lamp (tit) is lit.

, T using the tyring signal of T, input this tying signal through the connection circuit (1" 4), dial pulse detection part H, main part (1 station, pulse sending part (1 phrase), switch It is possible to make speed dial calls via the circuit α and the branch connection circuit (7).Although the embodiment shown here only shows the above-mentioned functions, other functions can be added as an adapter type. It is also possible to do so.

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to connect a telephone that is talking to an outside line to the same telephone line without installing a wire for sounding a ringing buzzer or the like separately from the telephone line. It is now possible to easily transfer calls to other telephones, and since it is configured in an Attazu9 format, it is removably inserted between the telephone outlet and the telephone plug. It has a young fruit that does not require any trouble for installation and installation work, and can also be used to hold a call, display the busy state, and display the hold state, and can also be used as a dial link using a speed dial. It has the effect of being able to transmit signals, realizing multi-functionality, and making it possible to greatly improve usability.
