    • In a mobile terminal device, a hinge member and a conductive member provided on a chassis and functioning as an antenna are electrically contacted with each other through the slide operation of a chassis and thereby can be configured as an antenna usable in various use situations without providing a separate antenna. Consequently, the mobile terminal device is provided, the manufacture cost of which can be suppressed, the size and thickness of which can be reduced, and which can prevent antenna characteristics from degrading because the antenna is not provided at a portion gripped by a hand. In the device, a first chassis (101) has a radio circuit (112). A second chassis (102) has a ground plate (121) and is attached so as to be freely slidable with respect to the first chassis (101). A tilt hinge member (104a) rotatably connects the first chassis (101) to the second chassis (102), is fed from the radio circuit (112), and functions as an antenna together with the ground plate (121) when the hinge member is electrically contacted with the ground plate (121) through the slide operation of the second chassis (102).
    • 在移动终端装置中,设置在底盘上并用作天线的铰链构件和导电构件通过机架的滑动操作而彼此电接触,从而可以被配置为可用于各种使用情况的天线,而不提供 单独的天线。 因此,提供了移动终端装置,其制造成本可以被抑制,其尺寸和厚度可以减小,并且其可以防止天线特性降低,因为天线没有设置在由手握住的部分。 在该设备中,第一机箱(101)具有无线电电路(112)。 第二底盘(102)具有接地板(121)并被安装成可相对于第一机架(101)自由滑动。 可旋转地连接第一机架(101)到第二机架(102)的倾斜铰链部件(104a)从无线电电路(112)馈送,并且当铰链部件 通过第二机架(102)的滑动操作与接地板(121)电接触。
