Abstract

PURPOSE:To recognize surely who is a recipient desired from a transmitting party, by connecting a handset to a recipient side after processing electrically to the recipient in advance when a telephone set is used in common with plural persons. CONSTITUTION:An AC signal detecting circuit 5 is operated with an AC signal transmitted from a transmission side to a line 1, a data is fetched to a CPU11 via a code converting circuit 10 and the start of a call is confirmed. A CPU11 transmits a buzzer tone to the line 1 through a voice output circuit 23 and operates a relay 18 to disconnect the telephone set 2. When a transmitting party dials after the confirmation of buzzer tone and transmits a recipient code, this code is detected 7, converted 8 into a parallel signal and given to the CPU11 via an input I/09. The CPU11 collates this code with a code stored in a memory 12 with a key input 21 in advance, and when the recipient of this code is present, the relay 18 is turned off to connect the telephone set 2 to the line 1 and to display 20 the name of the code. If the said recipient is on another line, a relay 19 is operated and the call is transferred to the said telephone line.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a telephone set, and particularly to a telephone set for places such as an office, and more particularly to a telephone set for use by a plurality of people.

If a known telephone is shared by multiple people, it cannot be determined whether the communication is from Gaen at the time of reception.

Also, the recipient that the sender requests to call may be absent. Furthermore, the desired recipient may be located at another telephone.

In these cases, the sender does not get the desired recipient;
On the other hand, the recipient end up having to deal with a third party who is not the true recipient.

Therefore, the present invention was invented to eliminate the above-mentioned drawbacks.

The following description will be made based on examples.

A known telephone set corresponds to 2.3 in FIG. 1, where 2 is a dial and a circuit section, and 3 is a handset. To operate this telephone, the transmitting side sends an AC signal to line 1, rings the bell provided in the circuit section, and has the recipient pick up the handset, or picks up the handset 3 and dials. It is configured to flow a DC signal, select a station, and enter a communication state.

According to this method, the bell only rings upon reception, but the recipient is confused because it cannot be determined whether it is a school or not. If there is no true recipient, you will be bothering a third party. In the present invention, the AC signal of line 1 is connected to the capacitor 4f! : through, activates the AC signal detection circuit 5, and connects the code conversion circuit 1o to J.
m, input data through data bus 25 to CPUI 1,
Confirm that the call has started. The CPU 11 transmits all the buzzer sounds to the line 1 through the audio output port 23, and simultaneously switches the V relay 18 to disconnect the telephone at the 0NL end from the line. After confirming the buzzer, the sender or operator turns the dial and sends a DC signal of the receiver code.

This signal is detected through the DC signal detector 7 and resistor 6.

The detected serial signal is converted into a parallel signal by register 8, and then sent from input 1109 to CPU 1.
A memo is sent to the key input device 21 or the card input device 22 in advance. The information regarding this code stored in J-12 is called up and collated. 110
If the recipient of the code read from 9 is present at the seat, the control relay 18 is turned off, the telephones 2 and 3 are connected to the line 1, and at the same time the name of the code is displayed on the display device 2o.

If the information that you are on another telephone 10 has been stored in the memory 12 for a long time, the relay 18 is kept in the ON state, the handset is disconnected from the line 1, and the voice information indicating that the telephone is to be switched is output. Output from circuit 23 to υ line 1. Furthermore, the control relay 19 is operated to generate a DC signal, and the exchange is operated to switch the transmission to a predetermined telephone port.

According to the present invention, the receiver can reliably know who the sender's desired receiver is before starting a call, while at the same time eliminating the need for a third party to intervene on the receiver's side. This can reduce interruptions in normal business operations due to telephone calls.

Furthermore, it can be used for multiple purposes.

[Brief explanation of the drawing]

FIG. 1 shows an embodiment of the present invention, in which reference numerals 16, 17, and 24 are buffers, 13, 14 are address controllers, 25 is a data bus, and 261d is an address controller. FIG. 2 shows a circuit configuration in which, in addition to the display 20, a nupeeka 28 is provided near the handset in order to display the total volume of information stored in the memory 12 and is provided as information to the receiver. After receiving the recipient code, the CUPI commands the audio output circuit 23 to 1.
1015 controls the relay 25, passes through the buffer 26 and the audio amplification II] circuit 27, and outputs it to the noupika 28. 'T, 111
