Description

  The present invention relates to a mobile phone terminal that transmits and receives data by wireless transmission and reception.

  2. Description of the Related Art Conventionally, a cellular phone terminal that transmits and receives audio data by wireless transmission and reception includes a transmitter unit having a microphone unit, a receiver unit having a speaker unit, an operation unit having a numeric keypad, an on-hook key, and an off-hook key, and a liquid crystal display device The display screen part which consists of is comprised.

  In this mobile phone terminal, the telephone number of the called party input using the operation key unit is displayed on the display screen unit, so that the user can use the information on the operation key unit based on the display on the screen display unit. Can be input reliably. Also, in this mobile phone terminal, when a call is received, the telephone number of the caller is displayed on the display screen, so that the user can call the other party before answering the call (off-hook) You can know information about.

  In such a mobile phone terminal, character data is input using the operation key unit, and so-called mail transmission for transmitting the character data through the telephone line or character data sent through the telephone line is received. There has been proposed an apparatus configured to perform so-called mail reception in which this character data is displayed on a display screen section.

  In a mobile phone terminal having such a mail transmission / reception function, the display screen unit has a larger screen in order to facilitate the input of character data and to display the received mail well. It is desirable to provide.

  When the display screen is enlarged in this way, the apparatus configuration is increased in size. However, in order to maintain good portability in a mobile phone terminal, it is not preferable to increase the size of the device.

  For this reason, the conventional mobile phone terminal is described in, for example, an open patent publication (Japanese Patent Application Laid-Open No. 2003-179678: Patent Document) in order to prevent the apparatus configuration from becoming large while the display screen is enlarged. As shown in the figure, an operation key unit and a display screen unit are provided on separate casings, and these casings are slidably attached to each other.

In such a cellular phone terminal, when not in use, the casing provided with the operation key unit and the casing provided with the display screen unit are overlapped, and the casing provided with the display screen unit. By setting the operation key portion to be covered by the above, the device configuration can be reduced in size and good portability can be ensured. In this mobile phone terminal, in use, the casing provided with the operation key section and the casing provided with the display screen section are slid to each other so that the operation key section and the display screen section are connected in parallel. Good operability can be realized by making each exposed to the outside.
JP 2003-179678 A (pages 6 to 12: FIG. 2)

  By the way, in the mobile phone terminal as described above, it is necessary to provide some operation keys also on the casing provided with the display screen unit. If no operation key is provided on the casing provided with the display screen section, the casing provided with the operation key section and the casing provided with the display screen section are overlapped to cover the operation key section. When there is an incoming call in this state, these casings must be slid to expose the operation key part to the outside, and there is a possibility that the incoming call cannot be answered promptly. .

  Therefore, in such a mobile phone terminal, it has been difficult to sufficiently increase the size of the display screen portion so that the entire main surface portion of the housing is the display screen portion.

  Therefore, the present invention has been proposed in view of the above-described circumstances, and can increase the size of the display screen and efficiently store the operation key unit without increasing the size of the apparatus, and is multifunctional. It is intended to provide a convenient mobile phone terminal.

  In order to solve the above-described problems, a mobile phone terminal according to the present invention includes a main body housing portion including an operation dial portion and an operation key portion on one end side on one main surface portion, and on one main surface portion of the main body housing portion. And a sub-chassis part provided with a display screen part on a main surface part opposite to the side facing the main body case part. Is movable between a first position where the entire operation dial portion and the operation key portion are exposed and a second position where only a portion of the operation dial portion and the operation key portion are exposed. It is a feature.

  In this cellular phone terminal, when the sub-casing is in the second position, only part of the operation dial part and the operation key part are exposed. Some can be operated without moving the sub-casing.

  In the mobile phone terminal according to the present invention, when the sub casing is in the second position, a part of the operation dial part and the operation key part are exposed, and a part of the operation dial part and the operation key part is exposed. Since it can be operated, it is possible to quickly perform an operation such as answering an incoming call without moving the sub-casing section.

  Therefore, in this mobile phone terminal, it is not necessary to provide an operation key in the sub-casing section, and the display screen section is sufficiently enlarged so that the entire main surface section of the multi-casing section is the display screen section. Is possible.

  That is, the present invention can increase the size of the display screen and efficiently store the operation key unit without increasing the size of the apparatus, and can provide a multifunctional and user-friendly mobile phone terminal. is there.
