Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cellular radio telephone,
The present invention relates to a wireless telephone such as a cordless telephone or a premises wireless terminal.

[0002]

2. Description of the Related Art In conventional radio telephones, the actual number of cases is 6
As shown in Japanese Patent Application Laid-Open No. 1-7145, a main body is provided with a speaker and a microphone.

[0003]

In such a radio telephone, since the distance between the speaker and the microphone needs to be equal to the distance between the human ear and mouth, the length of the main body becomes large. , Not easy to store when not in use,
It is also inconvenient to carry.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a wireless telephone which has a good storability when not in use and is convenient to carry.

[0005]

In order to achieve this object, the present invention provides a microphone holding portion which can be projected from the main body.

In this case, when the microphone holding portion is housed in the main body, an operation button partially covered by the microphone holding portion is provided.

Further, when the microphone holding section is housed in one side of the main body and the microphone holding section projects from the main body, the microphone provided in the microphone holding section is placed on a line passing through substantially the center of the main body. Position it.

Further, the microphone holding portion is made of a soft material.

[0009]

In this wireless telephone, since the distance between the speaker and the microphone when the microphone holding portion is projected from the main body should be equal to the distance between the human ear and mouth, the length of the main body Can be made smaller.

Further, when the microphone holding portion is housed in the main body, by providing an operation button which is partially shielded by the microphone holding portion, the microphone housing portion can be used as a new operation switch arrangement surface. The surface area can be reduced, and the operation area of the operation button can be increased.

Further, if the microphone holding portion is housed in one side portion of the main body, the operation buttons can be easily arranged, and when the microphone holding portion protrudes from the main body, the microphone provided in the microphone holding portion. If is positioned on a line passing through almost the center of the main body, the angle of the main body with respect to the user is the same whether the main body is held by the right hand or the left hand.

If the microphone holding portion is made of a soft material, the user will not be injured even if the microphone holding portion hits the user when the microphone holding portion is moved from the housed state to the projected state. ..
