Abstract

An upper case (11) houses a control unit (microcomputer) (not shown) having its function blocks mounted on a rigid substrate (27), a display unit (liquid crystal display) (14) and an RF communication unit (not shown), while a lower case (12) houses an operation unit (18) having its function blocks, even if they are many, mounted on a key substrate (flexible substrate (28)) and a battery (29). The result is that an antenna (13) is disposed in an RF communication unit-carrying upper case, with the key operation unit (18) and the battery (29) disposed in the lower case, whereby, unlike a conventional device, function blocks are disposed in the upper and lower cases with associated functions closed to each other to provide a lighter, smaller, and thinner device.

Description

technical field [0001] The present invention relates to a mobile communication terminal constructed in such a manner that an upper case and a lower case can be folded one on top of the other by a hinge, and in particular, to a mobile communication terminal in which the upper The number of wires between the case and the lower case is reduced, and elements are arranged to reduce the thickness of the upper case and the lower case. Background technique [0002] Generally, a mobile communication terminal that can be folded by a hinge as shown in FIGS. 10 and 11 is known. [0003] Fig. 10 shows a first embodiment of the prior art, wherein, Figure 10A is a plan view showing that the case part is separated in an open state, the upper part of the figure shows the upper case side, and the lower part shows the lower case side, and Figure 10B is a side view with the case part separated. [0004] The upper case side in FIG. 10 is configured such that an antenna 41 and a liquid crysta...
