Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a novel handset that can be used by being worn on the head as necessary.

[Prior Art] In general, a handset includes a handset/receiver housing having a predetermined length and a curved shape, with both ends forming an earpiece, and a central part forming a gripping part; It consists of a handset (microphone) and a handset (speaker) that are housed inside the earpiece, and a curl cord that connects the handset housing to the phone body.When not in use, it is placed on the phone body. When in use, it is removed from the telephone body and placed between the earpiece and one ear. In this case, there are two types of telephones: desktop type and wall-mounted type, but both types have almost the same configuration of handsets and receivers, and most of them can be used in common. In addition, various types of one-piece handsets have recently been proposed that are compact and easy to carry, omitting the traditional telephone body by incorporating a dialing mechanism, a communication circuit network, a control circuit, a switch, etc. into the handset housing ( Example Publication No. 62-16050).

[The problem that the idea aims to solve]

By the way, all conventional handsets are used by holding the handset case with one hand, so if you need to perform manual tasks such as taking notes or checking documents while on the phone, hold the handset case with one hand. Because it grips the body,
There was a problem that they were unable to perform their manual tasks smoothly and accurately, and that they often became too hasty and became sloppy in their manual tasks or lacked concentration on the phone, resulting in long call times.

Therefore, commercial employees and other people involved in telephone work sometimes use the handset with their shoulders pressed against their faces, but in this case, the posture is unnatural and easily tiring, making it unsuitable for long phone calls. .

SUMMARY OF THE PRESENT DISCLOSURE The present invention has an object to solve the above-mentioned problems and to provide a handset which has a simple structure and can be worn on the head like an earphone when necessary.

[Means to solve the problem]

In order to achieve the above object, the handset according to the present invention includes a handset housing which is curved inward and has both ends forming a transmitter and an earpiece, and a central part forming a gripping part, and a handset housing that curves inward. The handset includes a transmitter provided in a mouthpiece, and first and second receivers provided in an earpiece of the handset/receiver housing, wherein the first receiver is disposed in the earpiece, and the first receiver is provided in the earpiece. 2. The handset is provided at the tip of a retractable lead wire plate that is curved to fit the temporal region and the top of the head and is housed in the handset housing so as to be freely drawn out. It is housed on the upper surface of the earpiece.

[Effect]

In the present invention, the handset/receiver housing is equipped with an expandable lead wire plate, and when the lead wire plate is housed in the housing, it constitutes a normal handset, and when the lead wire plate is pulled out, it is attached to the head together with the handset/receiver housing. When worn, it forms an earphone-type handset. Therefore, there is no need to hold the handset casing or press your face against it with your shoulder.
