A mobile telephone ( 1 ) comprises an LCD (liquid crystal display) screen ( 2 ) for visually displaying data items ( 2 a), status and other relevant information to a user. The mobile telephone ( 1 ) includes a keypad ( 3 ) to enable a user to input information such as numbers or letters, and some functions of the telephone may also be accessed and/or selected by means of the keypad ( 3 ). The mobile telephone ( 1 ) further comprises a rotary scroller input means ( 4 ) located on the side of the telephone for convenient operation thereof by a user. The input means ( 4 ) is mounted in the housing of the telephone ( 1 ) such that only a portion ( 7 ) thereof is visible and accessible to the user externally of the telephone housing. The rest of the input means ( 4 ) is mounted within, and obscured by, the housing of the telephone ( 1 ). In fact, the 'invisible' portion of the input means ( 4 ) is located directly behind the display screen ( 2 ), with the axis of rotation ( 6 ) of the input means ( 4 ) being substantially perpendicular to the plane of the screen ( 2 ). The "invisible" portion of the input means ( 4 ) is represented (both visually and operationally) on the screen ( 2 ). |
