2. Description of the Related Art With a hands-free telephone, a telephone call can be made without having a telephone handset (handset). One of them is a hands-free one that has a speaker and a microphone built into the telephone itself, but it is rarely used because it is easy for surrounding sounds to enter and the confidentiality cannot be maintained.

For these reasons, the use of headsets or ear-hook type earphone microphones (ear microphones) is currently the mainstream. Although many proposals have been made for making a telephone having a handset hands-free, FIG. 3 shows a first conventional example in which the telephone is easily made hands-free without modifying the telephone.

In the first conventional example, the cord of the handset 2 is removed from the connection jack 1a of the telephone 1, and instead, the headset 3 (or ear microphone) having the microphone 3a and the headphone 3b is connected to the connection jack 1a. By doing so, we are aiming for hands-free operation. In this case, the handset 2 removed is used as a dummy in order to bring the telephone 1 into the on-hook or off-hook state.

FIG. 4 shows a second conventional example in which the telephone itself is hands-free without modification. In the second conventional example, a handsfree adapter 4 having no dial function is provided in the lead-in wiring of the telephone set 1, and a headset 3 (or ear microphone) is connected to the handsfree adapter 4 for use.

Although any of the conventional examples can be made hands-free without modifying the telephone itself, the first conventional example has the following problems to be solved.

That is, the connection jack 1a of the handset 2 is provided with a total of four terminals including two lines of the microphone line and two lines of the speaker line, but the arrangement thereof varies depending on the specifications of the telephone manufacturer. It is necessary to switch the terminal arrangement of the plug of the headset 3 so as to meet the manufacturer's specifications. In addition, the unused handset 2 must be left as a dummy, or a substitute for it must be prepared and used for the hook operation.

Further, in the case of the adapter system of the second conventional example, although it can be used for a two-line type telephone, a control line is included in a four-line type business phone, for example, a connection such as switching of a dip switch is made. The initial setting of is required. Not only that, but when such connection switching is performed, the telephone may be modified in a sense and the manufacturer's warranty may not be covered.

The present invention has been made to solve the above-described problems, and an object thereof is to make it possible to easily make an existing telephone having a handset hands-free as it is without modifying it. To provide a hands-free telephone coupler.
