Abstract

PURPOSE:To confirm the operating state of a telephone set not limiting to from the close location to a telephone set by constituting the circuit with a display circuit controlling a display light displaying the operating state of a telephone line, a display circuit controlling the display light displaying the operating state of a main body and an external display light connected to the display circuits. CONSTITUTION:The circuit consists of a display circuit 1 controlling a display light displaying the operating state of a telephone line, a display circuit 2 controlling a display light displaying the operating state of a main body, relays 3, 4 connected to the display circuits 1, 2 and external display lights 5, 6 connected to contacts of the relays 3, 4. Thus, the external display lights 5, 6 are placed to a location apart from the telephone set main body and the large and bright external display lights 5, 6 are used by using commercial power supply for a power supply 12. Thus, the user can recognize the operating state of the telephone set at a remote location without access to the telephone set main body.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a circuit for a telephone with an operating status indicator light.

[Prior Art] Conventionally, in order to indicate the operating status of a telephone to a telephone user,
2. Description of the Related Art Various types of telephones with operation status indicators are known, which are equipped with indicator lights that are linked to operations such as incoming and outgoing telephone calls.

For example, if the surroundings of the telephone are noisy and the sound emitted by the telephone cannot be heard when the telephone receives an incoming call, a telephone is provided that uses light to notify the user of the incoming call. Furthermore, as modern telephones have become more multi-functional, many telephones are equipped with indicator lights that display operating statuses such as transfer of calls between multiple telephones and temporary hold of calls. Furthermore, when a telephone line is shared by multiple telephones, some telephones are equipped with an indicator light that displays the usage status of the telephone line. In other words, it displays the operating status of the telephone line, such as whether or not the user can make a call. For example, if the telephone line is in a state where it is not possible to make a call, an indicator light lights up to notify the user. be.

[Problem to be solved by the invention]

As mentioned above, some current telephones are equipped with a function of displaying an indicator light to indicate the usage status of the telephone line. Although convenient, the problem remains that the display is mounted on the phone and can only be recognized from very close to the phone.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides, in a telephone equipped with an operation status display light, a display that displays the usage status of the telephone line to which the telephone equipped with the operation status display light is connected. a display circuit 1 for controlling a light; a display circuit 2 for controlling a display light for displaying the usage state of the main body of the telephone with an operating status display light; a relay connected to the display circuit 1 and the display circuit 2;
The present invention provides a circuit for a telephone with an operating status indicator light, which is characterized by comprising an external indicator light connected to the contacts of the relay.

[Example] Hereinafter, a preferred example of the present invention will be described using FIG. 1. FIG. 1 is a circuit diagram of the present invention.

(1) is the indicator light installed on the phone body. (2) is also the indicator light, (3) is the relay coil connected to the circuit of indicator light (1), and (4) is the display. This is the relay coil connected to the light (2) circuit. (5) is an external indicator light, and (6) is an external indicator light. (7), (
8) is a contact point of relay (3) and a contact point of relay (2), which correspond to the coils of relays (3) and (4).
The black circles in (9) and (10) are the input terminals for signals according to the operating state of the telephone, respectively.
It is. (11), (12) are indicator lights (1), (2), external indicator lights (5), (6), and relays (3), (4)
This is the power source for driving the . The mechanisms for generating inputs (9) and (10) are not directly related to the present invention and are therefore omitted.

Further, since resistors, diodes, etc. are not directly related to the present invention, their numbers are not shown in the drawings.

[Effect]

An indicator light (1) is an indicator light that indicates the usage status of the telephone line, and an indicator light (2) is an indicator light that displays the usage status of the main body. The indicator light (1) shall be lit when the telephone line is full and the telephone cannot be used. When there is an input (9) that turns on the indicator light (1),
The coil of the relay (3) is driven and the contacts (7) of the relay (3) are closed. Then, the external indicator light (
5), and the external indicator light (5) lights up.

Similarly, when there is an input (10) that turns on the indicator light (2), the coil of the relay (4) is driven, the contacts (8) of the relay (4) close, and the external indicator light (6) turns on. Turn on the light.

[Effects of the Invention] Since the present invention is comprised of the circuit configured as described above, the external indicator lights (5) and (6) can be installed at a distance from the main body of the telephone, and the power supply (12) can be By using a commercial power source, the external indicator lights (5) and 6) can be made larger and brighter. External indicator lights (5) and (6) can be installed in conspicuous places with any size and brightness. For example, when the telephone cannot be used because the telephone line is full, the external indicator light (5) lights up, allowing the user to know the operating status of the telephone from a distance without having to approach the main body of the telephone. It has the advantage of being able to judge whether or not it can be used. The present invention also has the advantage that it can be implemented with only slight modifications to the circuitry on the main body side of a conventional telephone with an operating status indicator light.
