本発明は親子式インターホン装置に関するもの
であり、子機から親機を呼出した時に親機に発呼
した子機の局番を表示させることを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a parent-child type intercom device, and an object of the present invention is to display the station number of the calling device on the parent device when the parent device is called from the handset.
従来、子機からの呼出し時に親機に局番表示を
行なわせる方式のインターホン装置では、各子機

であつた。しかしながらこの様な装置では親機に
子機数に比例した数の配線をしなければならず、
しかも各階毎に部屋番号が変わる高層住宅、マン
シヨンなどで部屋番号と局番とを一致させること
は極めて困難であるという欠点があつた。 Conventionally, in intercom devices that display the station number on the base unit when a call is made from the handset, a station number is set in advance for each terminal to which each handset is connected, and when a call is made from the handset, the station number of the terminal is displayed digitally. The so-called individual wiring method of display format was common. However, with this type of device, the number of wires must be connected to the parent unit in proportion to the number of slave units.
Moreover, it is extremely difficult to match the room number and station number in high-rise residential buildings, condominiums, etc. where room numbers change on each floor.
本発明は、この様な欠点を除去したものであ

置を提供するものである。 The present invention eliminates these drawbacks, and provides a wire-saving parent-child system that allows the addition of slave units without increasing the number of wires, and also allows for easy matching of room numbers and station numbers. The present invention provides an intercom device.

択信号線Rl及び通話線SPlを複数の子機R1，R2，
R3……を結ぶ並列配線７に接続する。 To call the slave unit R4 in room 4 on the 3rd floor (room number 304), first operate the numeric keypad dial section 1 of the base unit M and send a dial pulse "304". As a result, the base unit M displays the number "304" on the digital display section 5 through the signal switching section 4, and also sends a calling signal to all the relay adapters F 1 , F 2 . . . through the signal lines Fl and Rl of the parallel wiring 6. Send out. However, since the relay adapter selection signal is "3", only the corresponding relay adapter F3 is activated. In other words, since "3" matches the station number preset by the station number setter 17 of the relay adapter F3 , the calling signal transmitting/receiving circuit 16 sets the relay 18.
is activated, relay contacts 20 and 21 are closed, and the handset selection signal line Rl and speech line SPl are connected to multiple handsets R 1 , R 2 ,
Connect to the parallel wiring 7 that connects R 3 .

Flを介して親機Ｍに送出する。 Next, in order to call the base unit M from the slave unit R 2 in Room 2 on the 4th floor (room number 402), the call switch 29 of the slave unit R 2 is first closed, and the transmission control circuit 30 is activated. By doing this, the calling signal transmitting/receiving circuit 25 operates the relay 26 to close the contact 27, and also operates the station number setter 24 to send the dial pulse "02" to the parallel wiring. Furthermore, this dial pulse signal is transmitted to the relay adapter R4 on the 4th floor.
The dial pulse signal is received by the transmission control circuit 19, operates the relay 18, closes the contact 20, sends the dial pulse signal sent to the parallel wiring 7 to the base unit M via the signal line Rl, and enters the transmission state. The station number setter 17 is set by the set calling signal transmission/reception circuit 16.
The dial pulse “4” sent from the signal line
Send to base unit M via Fl.

あることを表示する。 In this way, the dial pulse "4" is applied to the main unit M from the relay adapter F4 via the relay adapter selection signal line Fl of the parallel wiring 6, and the dial pulse "4" is applied to the terminal 22-
The dial pulse "02" from the handset R2 is also sent to the base unit M at the same time through the terminal 14, the relay contact 20, the terminal 12, and the slave unit selection signal line Rl. With these dial pulses "4" and "02", the calling signal receiving section 3 of the base unit M activates the calling oscillator OSC and the speaker SP to perform a calling,
"402" is displayed on the digital display section through the signal switching section 4, indicating that the calling station is the slave unit R2 of "402".
