Next, (2) By arranging the battery on the microphone side, when the hinge is opened at the start of use, the heavy battery moves in an arc shape and stops, so there is an instability such as when dropping with one hand operation. there were. Also,
This structure (3) causes a feeling of instability and fatigue because a heavy battery is separated from the holding position during a normal call in which the speaker side is held and pressed against the ear. Further, (4) since the operation key is not provided on the speaker side, the state of the hand supporting the key during key operation differs from the state of the hand during a call, and it is difficult to perform one-handed operation because the user has to change hands.

An object of the present invention is to solve the above-mentioned problems relating to operability, and to provide a portable mobile telephone which is sufficiently convenient to use even with one hand, from preparation for a call such as dial operation to during a call.

[0005]

In order to achieve the above object, according to the present invention, a folding type portable mobile telephone is provided with a speaker, operation keys and a battery in a main body, and can be opened and closed by a hinge in the main body. The connected cover was provided with a microphone and a display unit. In addition, with regard to an integrated type mobile mobile phone that is not a foldable type, operation keys are provided on the speaker side and a display unit is provided on the microphone side.

[0006]

[Operation] Regarding the folding mobile phone, first of all,
Since the display unit is located far from the speaker, that is, on the cover separated from the hinge, the display unit does not come in contact with the cheeks during a call, and fat and cosmetics do not adhere (1).
The problem of was solved. Next, by arranging the battery and the operation key on the main body side having the speaker, when the hinge is opened at the start of use, only the light cover is opened, and the problem (2) is solved. Further, this structure solves the problem of (3) by holding the main body side having the speaker and holding the heavy battery reasonably during a normal telephone call performed by pressing the main body side against the ear. Furthermore, since the operation keys are on the main unit side with the speaker, the state of the hand that supports the keys when operating them and the state of the hands when talking are the same, so there is no need to change the hand and one-handed operation is easy. The problem of (4) was solved.

In the case of an integral type mobile mobile phone that is not a foldable type, the operation keys are provided on the speaker side and the display section is provided on the microphone side, so that the display section is located away from the speaker, so that it is possible to make a call. The display part does not contact the cheeks, and the fat content and the cosmetic agent do not adhere, and the problem of (1) is solved. In addition, from the structural features of the integrated type,
The problems (2), (3), and (4) essentially do not exist, and one-handed operation is easy.
