A folding mobile telephone having an upper terminal body and a lower terminal body is provided. The upper terminal body has an upper part with a liquid crystal display and a base, such that the upper part and the base are connected to each other via lock mechanism. This lock mechanism permits the upper part and the base to be mounted and removed in a flipping manner. The upper terminal body also has communications devices to make electrical connections. The upper terminal body has an operating mechanism that allows prescribed operations to be performed using the upper terminal body when it is connected to its base and folded against the lower terminal body (i.e., the closed state).

Portable terminal device capable of displaying information in a closed state

A foldable and portable mobile communication terminal is formed as a two-folded type in which a lower-side body unit and upper-side unit are coupled openably and closably by a two-shaft hinge mechanism. The two-shaft hinge mechanism includes a first hinge unit that allows the upper-side body unit to rotate with respect to the lower-side body unit up to the open state defining a predetermined talking position, and a second hinge unit that allows the first hinge unit to rotate in a direction different from the aforementioned rotational direction of the first hinge unit. The first and second hinge units are coupled so that the rotational center axes thereof orthogonally intersect each other.

Foldable and portable mobile communication terminal

A first and a second unitandwith components mounted thereon in correspondence to respective function blocks, into which portable telephone set functions are grouped, are capable of being slidably moved between a stacked state position and an extended state position. The first unitincludes a first component-mounted part having a displayand a receiver. The second unitincludes a second component-mounted part, which is covered when the stacked state position is brought about and exposed when the extended state position is brought about. The second unithas a notch, in which a first and a second auxiliary unitandare provided. A desired component-mounted part can be exposed and operated by causing selective sliding of the first and second unitsandand the first and second auxiliary unitsand
