Abstract: An operating unit is configured in such a manner as to freely slide with respect to a main unit. Furthermore, the operating unit and the main unit are electrically and mechanically connected by a resilient cable member having a spiral winding. The resilient cable member having a spiral winding includes an FPC stuck to either one surface or both surfaces of a resilient member having a spiral winding. The present invention facilitates the electric and mechanical connection between a main unit and an operating unit in a portable information terminal.

Abstract: A remote (or wire) control auxiliary push button dialing system includes a push button device, and a mobile telephone auxiliary dialing device. The mobile telephone auxiliary dialing device together with a mobile telephone is mounted in a receptacle. The push button device includes a keyboard push button and a key signal processor. The mobile telephone auxiliary dialing device includes a signal receiving controller, a pair of X/Y axis sliding arms, and a press module. In such a manner, the signal receiving controller receives push button coding signals transmitted by the push button device to serially control the pair of X/Y axis sliding arms to move longitudinally and transversely to fixed coordinate positions so as to further perform auxiliary push button dialing action of the mobile telephone by the press module.

Abstract: A mobile phone with replaceable key assemblies. The mobile phone comprises a body, a printed circuit board, and a key assembly. The printed circuit board, including a plurality of pads, is disposed on the body. The key assembly, including a plurality of keys corresponding to the pads of the printed circuit board respectively, is disposed on the body in a replaceable manner.

Abstract: A mobile phone housing top of the present invention comprises a main body and a front wall, a rear wall, a left wall and a right wall depending from the main body. The main body comprises a speaker section, a display section, and a keypad section including a function key section and a data key section. The data key section comprises a plurality of oblique recesses and a number of data key receiving openings respectively defined in the oblique recesses. The data key receiving openings are aligned with the oblique recesses while at the same time being arranged in a matrix which is conventional for mobile phone data keys. A protrusion is formed between adjacent oblique recesses.

Abstract: A portable telephone allowing the increase of the number of key buttons and the expansion of the area of the display window simultaneously is disclosed. The portable telephone is composed of three units: display unit, speaker unit, and body. The three units are connected at variable angles by means for two hinge shafts. Additionally, the lateral walls are formed on the body to generate friction between the units. Consequently, the tilt angle of the display unit with respect to the body can be held stably to further improve visibility for the user.

Abstract: A radio telephone is provided with a body (3) and a cover (2) arranged for relative sliding movement with the body (3). The radio telephone also comprises guide means for guiding the relative sliding movement, the guide means comprising a guide track on the cover (2) and a guide rail on the body (3). The guide rail extends along a portion of the guide track when the cover irrespective of the relative positions of the cover (2) and body (3) and the force between the cover (2) and body (3) is substantially constant over a range of positions along the guide track, which leads to a tactile improvement for the user. Alternatively, the guide rail may be provided on the cover (2) and the guide track on the body (3).

Abstract: A pocket personal computer having improved battery compartment enclosing structures is disclosed. The battery compartment enclosing structures include a battery compartment defined in a rear side of the pocket personal computer for accommodating a battery therein, a battery compartment cap for enclosing the battery compartment and an unlocking means form unlocking the cap. The battery compartment has two positioning openings defined in a rear side wall of the compartment and a bulge inwardly formed on an inner face of a front side wall and the bulge has a slanted upper face and a flat lower face. The cap has two protrusions formed at a rear end thereof which can be received in the openings as the cap is positioned over the compartment and a latch downwardly formed at the front end of the cap and the latch has a slanted lower end and a depressed neck portion to cooperate with the bulge to lock the cap in position.
