(Embodiment) An embodiment of the present invention is shown in FIGS. 1 to 4.
First, the basic configuration of the indoor communication alarm will be explained. In this indoor communication alarm, the main device 1 is installed in a room where family members are likely to be present, for example, the kitchen, and the transmitter ₂ is installed in each room such as the bathroom, toilet, children's room, or elderly parent's room. Install 2 _{and 3} respectively. As shown in FIG. 2, the transmitters 2 ₁ to 2 ₃ are equipped with a call button 6 that is pressed when an elderly or sick person calls a family member, for example. The main device 1 includes indicator lights 3 1 to 3 ₃ that indicate in which room the transmitters 2 ₁ to 2 ₃ are operated when the call buttons 6 of the transmitters _{2 1 to} 2 ₃ are pressed. , and a buzzer 5 as a notification device that emits a notification sound when the call button 6 of any of the transmitters 2 ₁ to 2 ₃ is operated.
Note that since the person operating the transmitters 2 ₁ to 2 ₃ does not know whether there is someone on the main device 1 side, the response call buttons 21 ₁ to 21 to which the person on the main device 1 side responds are used.
21 ₃ is provided in the main device 1, and the transmitter 2 is also provided with a buzzer 22 as a notification device that emits a response sound on the transmitter 2 side when the response call buttons 21 ₁ to 21 ₃ are pressed. In addition, the above response call button 2

A more specific explanation will be given with reference to FIG. The main unit 1 uses an alternating current power source (AC100V) as a power source, and has a power supply intake part consisting of an isolation transformer T and a diode bridge DB that take in this alternating current power, and a constant voltage that converts the output of this power supply intake part to a predetermined voltage. A constant voltage section 8 is provided with a constant voltage circuit 9 that converts into a constant voltage circuit. Note that the constant voltage section 8 described above is connected to each transmitter 2.
It supplies power in common to the unit circuits corresponding to the . Further, as the insulating transformer T, a separate winding type transformer is used to prevent electric shock accidents in the bathroom. A unit circuit corresponding to one transmitter 2 includes a connection circuit section 10, a display section 16, a response calling circuit section 26, and a notification sound generation section 18. In the following description, a unit circuit corresponding to the transmitter 2 ₁ shown at the top of the main device 1 in FIG. 2 will be explained as an example. The connection circuit section 10 consists of a call detection section as a call detection means and a short circuit protection circuit section, and the call detection section detects the pressing operation of the call button 6 of the transmitter 2, that is, in the case of this embodiment, the main device 1 and transmitter 2, e.g.
When T ₁₁ and T ₁₂ are short-circuited, the operating state of the call button 6 is detected by detecting the current flowing between the two wires, and the operation state of the call button 6 is detected by transistors Q ₃ and Q ₄ and resistors R ₁ and R ₂ The short-circuit protection circuit section prevents the constant voltage section 8 from being destroyed when the call button 6 is pressed.
It consists of Q ₂ , diode D ₁ and resistor R ₃ .
Note that a constant voltage from a constant voltage circuit 9 is applied between T ₁₁ and T ₁₂ via a transistor Q ₂ and a resistor R ₁ , and a constant voltage is applied between the signal lines by the constant voltage section 8 and the connecting circuit section 10. A constant voltage means for applying voltage is configured. The display unit 16 lights up for an arbitrary period of time from when the call button 6 is operated, and turns off naturally after this time has elapsed to indicate which call button 6 of the transmitter 2 has been operated. , an inverter I that inverts the output of the transistor _Q3 , a diode _D2 , a resistor _R3 , a capacitor _C1 , and a capacitor _C2 and a resistor _R6 that are common to the unit circuit. The notification sound generator 18 emits a notification sound while the call button 6 is pressed, and the basic oscillation circuit 19 that determines the sound of the buzzer 5 and the call button 6 of any of the transmitters 2 are pressed. The switch circuit 20 includes a transistor Q6, which applies the output of the basic oscillation circuit 19 to the buzzer ₅ to make the buzzer 5 sound when a signal is generated, and a switch circuit 20 including diodes _D11 to _D13 .
In this embodiment, the display unit 16 and the notification sound generating unit 1 are used as a notification device that notifies the call from the transmitter 2 using the detection output of the connection circuit unit 10 as a call detection means.
It consists of 8. The response call circuit unit 26 includes response call buttons 21 ₁ to 2 that are operated when calling the transmitter 2 or when a call is received from the transmitter 2.
1 ₃ and a transistor Q ₅ , and when calling the oscillator 2 or responding to a call from the oscillator 2, transmits the output of the basic oscillator circuit 19 to the oscillator 2 via the connection circuit section 10 and transmits the signal. This is to make the buzzer 22 of the device 2 sound. Here, in this embodiment, when any of the response call buttons 21 is operated, a call signal or a response signal is sent out via the signal line, and a ring tone or A response sound sending means for generating a response sound is composed of a basic oscillation circuit 19, a response calling circuit section 26, and a connection circuit section 10.

The operation of this embodiment will be explained below. First, assume that a certain call button 6 is pressed to call a member of a family member who is present at the main appliance 1 installed in the kitchen, for example. When the call button 6 of the transmitter 2 is pressed, the wires connecting the main device 1 and the transmitter 2 are short-circuited. Due to this short circuit caused by the call button 6, the current flowing through the resistance _R1 of the transmission detection section increases. Therefore, the voltage across the resistor _R1 increases, turning on the transistor _Q4 , and turning on the transistor _Q4 turns on the transistor _Q3 . At this time, the output inverted via the inverter I becomes low level, so the display section 1 corresponding to the pressed call button 6
6 indicator light 3 lights up. Note that this display section 16
The indicator light 3 is connected to the display section 16 as shown in FIG. 3q.
The same figure continues until an arbitrary time T seconds set by the time constants of the capacitors C ₁ and C ₂ and the resistor R ₆ elapses, or until the response call button 21 is pressed as shown in j to l of the figure. It continues to light up as shown in n to p.
In the notification sound generation section 18, when a call is received from any of the transmitters 2, the transistor _Q6 becomes conductive, thereby applying the output of the basic oscillation circuit 19 to the buzzer 5 and causing the buzzer 5 to emit a ringing sound. Note that the buzzer 5 is designed to emit a notification sound only while the call button 6 is pressed. Figure 3 a, c, e,
When the call buttons 6 are pressed as shown in g, the buzzer 5 of the main device 1 sounds as shown in i in the figure in accordance with the pressed state of each call button 6. Then, when a person in the room where the main device 1 is installed hears this notification sound and presses the response call button 21 as shown in FIG. The output is applied to the transmitter 2 via the response calling circuit section 26 and the connecting circuit section 10, and the buzzer 22 of the transmitter 2 sounds as shown in FIGS. 3b, d, and f. Therefore, the person who made the call can confirm from this response tone that the person on the main device 1 side has noticed the call. Note that when the response call button 21 is pressed as shown on the right side of FIG. The buzzer 2 of the transmitter 2 is activated as shown in d and h of the same figure.
By ringing 2, a person on the side of the transmitter 2 can be called.

As described above, according to the present embodiment, by pressing the call button 6 of the transmitter 2, it is possible to call a person in the room where the main device 1 is installed, and the response call button 21 ₁ of the main device 1 can be called. ~21 ₃ can call the person on the transmitter 2 side, thus improving family communication, and the main room communication alarm can be used to contact the elderly and sick for assistance. You can also do it. Furthermore, the main unit 1
is equipped with indicator lights 3 ₁ to 3 ₃ that indicate which transmitter 2 is calling, so you can accurately know which room the call is from, and the buzzer 5 sounds at the same time as the display. It is possible to reliably call a person who is on the side of the main device 1.

₁ to 2 ₃ are equipped with a call-only device 11 having only a buzzer 22 without the call button 6, and by pressing the call button 21' arranged on the main device 4 together with the call response buttons 21 ₁ to 21 ₃ . , the buzzer 22 of the paging device 11 is sounded so that the person in the room where the paging device 11 is installed can be called.
The circuit corresponding to the unit circuit of the transmitter 2 on the main device 1 side corresponding to this calling device 11 is a transistor Q ₂ shown in FIG. No other circuits are required. In other words, when the call button 21' is pressed as shown in FIG.
Since the signal is applied to the calling unit 11 through Q ₅ , the calling button 21', and the transistor Q ₂ , the buzzer 22 sounds as shown in FIG. 3g in accordance with the output of the basic oscillation circuit 19.
