[0029]FIG. 1 is a perspective view showing a state in which a mobile telephone of the present invention is opened. As shown in FIG. 1, in a portable terminal device, i.e., a mobile telephone of the first embodiment, an upper terminal body 11 and a lower terminal body 12 are provided. The upper terminal body 11 and the lower terminal body 12 have operating buttons for inputting telephone numbers, text, etc. on their inner surfaces. The upper terminal body 11 and the lower terminal body are connected via a hinge 13 so as to be opened and closed. The electronic circuits (not shown) required for mobile telephone functions, e-mail functions, and Internet functions are internally packaged. Hereinafter, the upper terminal body 11 serving as a major part of the present invention will be discussed in detail.
[0033]FIG. 2 is an exploded perspective view showing the mobile telephone. As shown in FIG. 2, the connector 103 comprises a male connector 107, which is connected to electronic circuits packaged inside the upper part 101 and protrudes on the lower surface (connecting surface with the base) of the upper part 101. The connector 103 further comprises a female connector 108, which is connected via the hinge 13 to electronic circuits packaged inside the lower terminal part 12 and can be detachably fit onto the male connector 107 in the top face (connecting surface with the upper part) of the base 102. The male connector 107 and the female connector 108 are engaged to each other to electrically connect the upper part 101 and the base 102.
Referring to FIGS. 5-8, the second embodiment will be discussed below. This second embodiment is an example in which an interlocking mechanism is used as lock means and a radio system is used as communication means.
[0039]FIG. 5 is a perspective view showing a state in which a mobile telephone of the present invention is opened. As shown in FIG. 5, an upper terminal body comprises an upper part 201, a base 202, a radio section (communication means: not shown), and lock means 203.
[0043]FIG. 6 is an enlarged longitudinal sectional view showing a connecting part when an upper part and a base of the mobile telephone are engaged to each other. As shown in FIG. 6, the engaging part 206 comprises an inner housing 208, which is fixed in the lower part of an upper case 21 a and has claws 209, pressing parts 210 for causing the claws 209 to project and retreat.
[0052]FIG. 7 is an enlarged longitudinal sectional view showing a state in which the upper part and the base of the mobile telephone are separated from each other subsequently to FIG. 6. As shown in FIG. 7, the operating parts 214 are pressed down, so that the ends of the core beams 215 press the bases of the claws 209 to elastically deform the claws 209 protruding on the sides of the protruding part 217, the claws 209 are stored in the grooves 211, and the engagement is released. In this state, the upper part 201 is removed upward, so that the upper part 201 is separated from the base 202.
[0054]FIG. 8 is a perspective view schematically showing that radio communication is performed while the upper part and the base of the mobile telephone are separated from each other. As shown in FIG. 8, since the mobile telephone of the second embodiment uses a radio system as communication means, the mobile telephone can be used while the upper part 201 is separated from the base 202. E-mail messages can be read or desired Internet sites can be viewed by using the small and lightweight upper part while the lower terminal body 22 is placed a short distance away, e.g., in a bag or under the table. This provides a mobile telephone which is quite excellent in portability.
