A conventional adapter is not required, so that the portability is improved, and the mobile computing terminal can meet the wireless data service needs of "anytime / anywhere". FIG. 4 is an external perspective view of a portable telephone device 1A according to a second embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals. In this embodiment, a key section 8 is provided on the sub-housing 3 to increase the area of the display section 7 of the main housing 2. That is, the display information on the display unit tends to increase with the diversification of mobile computing services, and when the area of the display unit is small, the display contents (characters, symbols, and the like) are also limited, and It is difficult to collectively display the displayed contents on the display unit.
As described above, the display contents cannot be displayed collectively, and it is difficult to realize the mobile computing function in the display unit having the specification in which the number of display digits and the number of display lines are limited. Therefore, in order to increase the area of the display section 7 in this embodiment, the key section 8 provided in the main housing 2 in the first embodiment is provided in the sub-housing 3, and substantially the entire surface of the main housing 2 is provided. Is provided with a display unit 7. In this embodiment, the key unit 8 is
In order to satisfy the thickness dimension of the IC memory card in the sub-housing 3, a switch composed of a flat-type switch using a touch screen film and having a key name described by printing or the like on its surface is used. In the portable telephone device 1A thus constructed, data communication by a personal computer can be realized in substantially the same procedure as in the first embodiment when used. In this case, when the sub-housing of the mobile phone device is inserted into the IC memory card slot of the personal computer, the key portion may be located in the slot and its operation may not be possible. 8
Is required to be disposed in an area that does not enter the IC memory card slot 101 of the personal computer 100. Alternatively, the key unit 8 of the mobile phone 1A may be operated by using operation keys provided on the personal computer 100 instead.
Further, after the line is first established by operating the key section 8 of the mobile phone 1A, the mobile phone 1A is connected to the personal computer 100, and thereafter, the communication is controlled by the operation of the personal computer. Is also good. Thereby, in the mobile phone device 1A, the number of digits and the number of lines of the display on the display unit 7 can be increased, and the mobile computing function can be realized. As shown in FIG. 6, the touch screen film 2 has a key portion 8 provided on the sub-housing 3.
1 and the liquid crystal device 22 may constitute the key unit 8 and the liquid crystal device 22 may be further constituted as a part 7A of the display unit 7. That is, as shown in FIG. 7, a liquid crystal device 22 having an area larger than that of the touch screen film 21 is disposed on the touch screen film 21 so as to show a cross-sectional structure along the line AA. The key unit 8 is constituted by displaying the key constituted by 21. Further, the liquid crystal device 22 is used alone to constitute the display unit 7A. With this configuration, the liquid crystal device 22 can be integrally formed with the display unit 7 as a display unit having an extremely large area, and the number of displayable digits and rows can be further increased. In each of the above embodiments, the sub-housing 3 is replaced with the main housing 2.
An example is shown in which it is foldable for
The same applies to a telephone device in which the sub-housing is pulled out from the main housing, or a part of the integrated housing is formed in the width and thickness dimensions of the IC memory card without distinction between the main and sub-housings. ,
An IC memory card connector may be provided at that portion, and the connector may be inserted into an IC memory card slot of an external device. In the above-described embodiment, an example of a personal computer is shown as an external device. However, the external device can be configured as a mobile phone device that can be connected to various devices including an IC memory card connector, such as a word processor and an electronic organizer. Needless to say. As described above, according to the present invention, the housing is constituted by the main housing and the sub-housing which can be folded or pulled out from the main housing, and this sub-housing is formed. It is inserted into the IC memory card slot provided in the external device to make connection with the external device, and various operations can be performed by operating the operation keys provided in the external device without operating the key portion provided in the second housing. Has the effect of realizing the operation of
