Abstract

(57) [Summary] [Purpose] The outlet for the attached telephone is unnecessary. [Composition] Commercial AC power is converted into DC power of a predetermined voltage by a power supply device 3. This DC power is supplied to the telephone 8 via the telephone connection terminal device 5 and the modular cord 10.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a facsimile apparatus capable of connecting a telephone requiring a power source such as an answering machine or a cordless telephone as an attached telephone.

[0002]

[Prior Art]

 Conventionally, the following types of facsimile machines have been known. That is, as shown in FIG. 2, a facsimile device 30 and a telephone 31 are connected by a two-core modular cord 33 via a telephone connection terminal device 32 having two terminals, and the telephone is connected via the modular cord 33. While the line 34 and the telephone 31 were connected, the power plug 35 of the facsimile device 30 and the power plug 36 of the telephone 31 were inserted into a socket (not shown) to obtain electric power. In addition, instead of the power plug 36, there is also a type in which a power adapter is inserted into an outlet.

[0003]

[Problems to be solved by the device]

 The conventional facsimile machine has the following drawbacks. That is, it is inconvenient because outlets are required near the installation positions of both the fax machine 30 and the telephone 31. Especially in general households, there is often no outlet near the desired installation position, and the installation position of the telephone 31 is restricted.

An object of the present invention is to provide a facsimile device which does not require an outlet for an attached telephone.

[0005]

[Means for Solving the Problems]

 This invention adopts the following means in order to solve the above-mentioned drawbacks. That is, a power supply device for converting commercial AC power into DC power of a predetermined voltage and a telephone connection terminal device composed of a plurality of terminals connected to the power supply device and a telephone line are provided, and the telephone connection terminal device and the telephone are provided. Are connected by a modular cord of at least four cores, DC power is supplied to the telephone through the modular cord, and the telephone is connected to the telephone line.

[0006]

[Action]

 This device has the following actions. That is, the commercial AC power is converted into DC power of a predetermined voltage by the power supply device. This DC power is supplied to the telephone through the telephone connection terminal device and the modular cord. Therefore, there is no need for a telephone dedicated socket.

【Example】

 The present invention will be described below based on an embodiment shown in the drawings. FIG. 1 is an overall configuration diagram of a facsimile device according to an embodiment of the present invention. In a facsimile device 1, a power supply device 3 having an input end connected to a power supply plug 2 and a power supply device via an operation switch 4 are provided. A telephone connection terminal device 5 including two terminals for a power source connected to an output terminal of 3 and a signal terminal device 7 including two terminals to which a telephone line 6 is connected are installed. The two terminals of the signal terminal device 7 are connected to the two terminals for signals of the telephone connection terminal device 5 via a switching circuit (not shown). That is, the telephone connection terminal device 5 is composed of a total of four terminals including two terminals for power supply and two terminals for signal. The telephone connection terminal device 5 of the facsimile device 1 is connected to the terminal device 9 composed of four terminals of the telephone 8 through a four-core modular cord 10. A connector 10a for connecting to the telephone connection terminal device 5 is attached to one end of the modular cord 10, and a connector 10b for connecting to the terminal device 9 is attached to the other end of the modular cord 10. .. The modular cord 10 is formed by arranging four cords in parallel in one row. The outer two cords are for power supply and the inner two cords are for signal.

Next, the operation of the embodiment apparatus will be described. AC power of 100 V supplied to the power supply device 3 through the power supply plug 2 is converted into DC power of a predetermined voltage of about 6 to 9 V and supplied to well-known circuits (not shown) of the facsimile device 1. At the same time, it is supplied to the two terminals for power supply of the telephone connection terminal device 5 via the operation switch 4. Then, this DC power is supplied to well-known circuits (not shown) of the telephone 8 through the two lines on the outside of the modular cord 10 and the two terminals for the power supply of the terminal device 9. On the other hand, when the line is automatically or manually switched from the facsimile device 1 side to the telephone device 8 side, the signal terminal device 7 and the two terminals for signal connection of the telephone connection terminal device 5 and the modular Input / output is performed between the telephone line 6 and the telephone 8 via the two lines inside the cord 10 and the two terminals for power supply of the terminal device 9. When a telephone that does not require a power source is connected to the facsimile apparatus 1, the operation switch 4 is operated to cut off the supply of DC power to the telephone connection terminal device 5 in consideration of safety.

Since the DC power is supplied to the telephone 8 through the modular cord 10 in this way, an outlet for the telephone 8 is not required and the installation position of the telephone 8 can be freely selected. Since the modular cord 10 is used, it can be easily extended and has an excellent appearance. Further, if the operation switch 4 is provided as in the present embodiment, it is possible to improve the safety when connecting a telephone that does not require a power source.

[0010]

[Effect of the device]

 The present invention has the following effects due to the above-described configuration. The telephone connection terminal device and the telephone are connected by a modular cord of at least four cores, and DC power is supplied to the telephone via this modular cord, and the telephone is connected to the telephone line. It is not necessary and you can freely select the location of the telephone set. Since it uses a modular cord, it can be easily extended and has an excellent appearance.
