 With the liberalization of this telephone connected to the telephone line, the functionality and diversification of telephones are rapidly increasing. Among them, cordless telephones that do not require a connecting cord between the master unit and the slave unit via a wireless transmission line are remarkable for their widespread use because of their mobility and convenience. In addition, there are various types of multifunctional phones on the market that pursue the functions of a phone as much as possible.

FIG. 5 is a specific example of such a conventional cordless telephone. In FIG. 5, reference numeral 21 is a master unit, 22 is a slave unit, 23 is an antenna, 24 is a push button, 25 is a display window for a telephone number and the like, and 26 is a telephone signal line and a power line. In this cordless phone, the base unit 21 and the handset unit 22 are connected by a wireless transmission path, so that it has the advantage that the handset unit 22 can be freely carried and used for calls within the range where radio waves can reach. There is.

On the other hand, a conventional conventional handset having a headphone type is also used. FIG. 6 shows a conventional example of a headphone type telephone. In FIG. 6, 28 and 28a are headphone type receivers, 29 is a transmitter, 27 is a connecting cord for connecting the base unit 21 and the handset 22, and the headphone type receivers 28, 28a and the transmitter 29 are connected. The child device 22 is configured. In this conventional example, since the child device 22 is fixed to the head and can communicate in a hands-free state, desired work can be performed with both hands free even during a call.

Next, FIG. 7 shows an example of a telephone in which the headphone of FIG. 6 is applied to the cordless telephone of FIG. 5, and 23 and 23a are antennas. The example shown in this figure has a configuration in which the cordless telephone and the headphone type telephone described above are combined, and has the advantage that the range of the call is wide and both hands can be used during the call.

[Problems to be solved by the device]

 However, the conventional example shown in FIG. 5 has a drawback in that it is necessary to always hold the slave unit 22 during a call, and it is difficult to perform a call during work using both hands. For example, it is very inconvenient if you need to interrupt cooking work at home while receiving a call while cooking, or if you are searching for a document or writing while talking in the office. It will be.

Next, the conventional example of FIG. 6 has an advantage over the example of FIG. 5 that both hands can be used during a call. However, there is an inconvenience that the headset must be fixed to the head with both hands when receiving an incoming call, and the work must be interrupted during the work with both hands or one hand. Since the cordless handset 22 is connected to the cordless handset 22, the movable range of the cordless handset 22 is limited to the length of the cord 27 and the cord 27 is bent and entangled.

Further, in the example shown in FIG. 7, although the drawbacks of the above two examples can be eliminated, it is still necessary to fix the headset to the head with both hands, and the external shape of the child device 22. If the size is inevitably larger than the size of the head, and you want to hold the handset 22 with one hand instead of fixing it to the head, as in the case of a telephone call when using a normal telephone, make sure that the headset part is in the way. There was a drawback that became.

The present invention has been made to solve the above-mentioned problems of the conventional telephone, and can be easily attached to or detached from one ear with one hand, and both hands can be freely used during a call. The purpose is to provide a cordless telephone handset structure that can be used.
