2. Description of the Related Art Conventionally, a tone ringer apparatus has been provided for notifying a call to an outside line other than ringing a bell of a telephone and for notifying only an outside call.

[Problems to be Solved by the Invention] However, since the conventional tone ringer device corresponds to one line, there is a problem that two tone ringer devices must be prepared in order to support a plurality of lines. .

Further, there is a problem that a device connected to a simple exchange device such as a home telephone does not operate when a power failure occurs on the side of the simple exchange device so that a call notification cannot be made.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to provide a tone ringer device capable of performing call notification corresponding to two lines, and which line is also calling and notification. A tone ringer device that can be identified by the notification sound, and further connected to an external device such as a simple exchange device such as a home telephone so that a notification can be made even if a power failure occurs. Another object of the present invention is to provide a tone ringer device which can respond to a voltage signal from an external device as a DC signal or a pulse signal.

 Next, the embodiment of FIG. 3 will be described.

In the call signal detecting means, the control circuit 37 which also serves as a driver informing means serving beeper 13 after extracting the calling signal 16Hz via a capacitor C ₁ and resistor R _1, a diode bridge DB and a capacitor C ₂ Rectifying and smoothing, and furthermore, a DC voltage made constant by the Zener diode ZD is applied between the pins as a power supply. When the power is supplied and the pin is at “H”, the operation is performed. ,
The output pin has a frequency determined by the time constant circuit consisting of the resistor R ₂ , the capacitor C ₃ , the resistor R ₃ , and the capacitor C _{4 connected} to the output pin. Capacitor C ₁ because line voltage is DC
The power supply cannot be obtained, and it does not operate.

When the pin is grounded and becomes “L”, the operation is stopped. The pin is connected to the power input terminal via the resistor R ₄ and the output transistor of the photocoupler PH is connected. Grounded through Q.
As the control circuit 37, there is a general-purpose IC which is commercially available for tone ringers.

Between the pin of the control circuit 37 connects the electronic buzzer 13 via a resistor R _5, both ends of the resistor R ₅ is further 3
By switching the contact 1 circuit slide switch 15, another resistor R ₆ or or is short-circuited so that the or connected in parallel. For example, slide switch
Maximum volume is set to short-circuit state illustrated 15, but also the intermediate volume is set to a state in which the resistor R ₆ is connected in parallel, further minimum volume is set to the state of the resistor R ₅ only is the respective selection.

As the slide switch 14 for setting the mode, a switch having four contacts and four circuits is used, and four modes can be switched and selected.
L ₁ and L ₂ are connected to the input terminal of the diode bridge DB via the capacitor C ₁ and the resistor R ₂ , and the voltage signal lines L ₃ and L
₄ is disconnected from the input side of the photocoupler PH. That is, when a call signal is superimposed on the lines L ₁ and L ₂ , the control circuit 37 operates to sound the electronic buzzer 13 and perform a call notification.

Next, when the slide switch 14 is switched to the second stage b, the connection state of the lines L ₁ and L ₂ is the same as that of the first stage a, but the lines L ₃ and L ₄ emit light on the input side of the photocoupler PH. Diode L
ED ₁ and LED ₂ are connected via resistor R ₇ .

That is, when a DC voltage signal is applied from an external device such as a simple exchange device A such as a home telephone through the voltage signal lines L ₃ and L ₄ , the photocoupler PH is turned on and the control circuit 37 is turned on.
Pin is set to “L” and the control circuit
In this mode, the operation of 37 is stopped and the call notification is stopped.

Of course, when the voltage signal lines L ₃ and L ₄ are not connected from the external device, the photocoupler PH is in the off state, so that the first
The operation mode is the same as the mode of the stage a. Here, if a power failure occurs while the voltage signal lines L ₃ and L ₄ from the external device are connected and the voltages are applied to the photo couplers L ₃ and L ₄ , Since no DC voltage is applied to the input side of the PH, the control circuit 37 is in an operable state, and when a call signal is superimposed on the lines L ₁ and L ₂ and input, a call notification can be made. In other words, it can respond to a power outage. Thus, the photocoupler PH constitutes control means for controlling the stop of the calling signal detection means comprising the control circuit 37 and the release at the time of power failure.

Further, when the slide switch 14 is switched to the third stage c, a mode is set in which the lines connected to the input terminal of the diode bridge DB via the capacitor C ₁ and the resistor R ₁ are L ₅ and L ₆ . In this mode, the operation of the control circuit 37 is the first stage a
This is the same as the mode switched to.

When the slide switch 14 is switched to the fourth stage d, the second
This is a mode in which the operation of the control circuit 37 which is the same as the mode switched to the stage b is stopped by the voltage signal.

FIG. 4 is a diagram showing a configuration in a case where the tone ringer apparatus B of the present invention is connected to the simple exchange apparatus A, in which H is a security device, K is a cutout device, and T is a telephone.

The circuit shown in FIG. 5 is provided with a photocoupler PH so that the operation stop mode of the control circuit 37 can be set whether the voltage signal from an external device such as a simple exchange device to be connected is DC or pulse voltage. pulse voltage is provided a rectifying smoothing circuit to the input side a diode bridge DB ₀ and a smoothing capacitor C ₅ is that to be able to drive the photocoupler PH be applied as a voltage signal.

The circuit shown in FIG. 6 switches the values of the resistances connected to the pins constituting the time constant circuit of the control circuit 37 at the same time when switching between the lines L ₁ and L ₂ and the lines L ₅ and L _6. The sound adjusting means is constituted so that the tone of the notification sound emitted by the electronic buzzer 13 is changed by changing the frequency generated by switching the time constant. , are the utilizing 2 circuit resistor R ₂₁ and R ₂₂ and R ₃₁ and R ₃₂ of which are switched respectively. In FIG. 6, the modular jack 4 is omitted.
Further the Figure 3, in the embodiment circuit of Figure 5 has a configuration which is connected to the input side or the diode bridge DB input of ₀ in the line L ₄ are switched not directly photocoupler PH, but slides in this embodiment The switch 14 is used to connect only when switching between the second stage b and the fourth stage d.
