Description

  The present invention relates to a wireless communication apparatus such as a mobile phone and a PHS, and more particularly to a wireless communication apparatus having a mechanism that allows a cover portion of the apparatus main body to slide.

  Conventionally, in wireless communication devices such as mobile phones and PHS, most of them are equipped with a telephone function in one casing, and a speaker, display means, operation keys such as dial keys, a microphone, etc. are arranged on the front of the casing. Therefore, the size is reduced, and portability and operability are facilitated. However, the operation keys such as the dial keys are exposed, and there is a problem that the mobile phone is inadvertently touched and malfunctions when being carried with the power on.

  Further, in order to diversify non-telephone service functions in addition to telephone functions, the number of display characters on the display means has to be increased.

  Therefore, some portable telephones that can be folded are also provided. In this foldable portable telephone, for example, a first part having a speaker and a display means, and a second part having a key operation part and a microphone, when not making a call (when carrying) Is folded so that the surface on which the first portion of the speaker and the display means are arranged faces the surface of the second portion on which the key operation unit and the microphone are disposed.

  As described above, in the folding type mobile phone, the key operation unit is also protected on the inner side in the folded state, so that it is possible to prevent malfunction due to careless contact. In addition, since the display means is provided on a different surface from the key operation unit, a large display area can be secured, and diversification of functions other than the telephone function, for example, non-voice services such as e-mail can be supported. .

  However, in the case of a foldable mobile phone, when the caller ID is notified by the call ID service or when message data is received, it must be opened from the folded state. Can not see immediately.

  In addition to miniaturization and ease of portability and operability, at the same time, in addition to the telephone function, in order to constantly monitor the status of message communication, etc. performed by the display screen, as a mechanism other than the folding type, a speaker and display means And the second part having the key operation unit and the microphone are slid relative to each other, and the first part and the second part when not making a call (when carrying) There is also provided a portable wireless communication device that overlaps the above portion. For example, in a radiotelephone proposed in Japanese Patent Application Laid-Open No. 9-247252, a speaker, a display means, and a key operation unit are provided on a telephone main body, and a cover provided with a microphone is placed on the telephone main body. It has a mechanism to slide and cover. When not making a phone call (when carrying), the cover part can be slid to cover the entire key operation part, and is also locked at an intermediate position so as to partially cover the entire key operation part. It is also possible. The speaker and the display means are exposed even when the cover portion covers all the key operation portions.

Similarly, as an example having a slide moving mechanism, JP-A-10-271192 can be cited. In this case, the operation panel unit having the microphone and dial operation key group slides relative to the main unit having the speaker and the display unit, so that the operation panel unit is stored under the main unit. And can be withdrawn. When the operation panel unit is stored under the main body unit, the operation panel unit cannot be operated.
