Abstract

A protective casing is provided for a mobile communication terminal, wherein the protective casing includes an input and/or output device and an interface for transmitting signals between the input and/or output device and the mobile communication terminal, and wherein the input and/or output device is arranged on a side of the protective casing which is on the inside of the protective casing in a closed state.

Claims

1. A protective casing (1, 3) for a mobile communication terminal (2, 4) having an input and/or output device (5) and an interface for transmitting signals between the input and/or output device (5) and the mobile communication terminal (2, 4),

where the input and/or output device (5) is arranged on a side (7) of the protective casing (1, 3) which is on the inside in the closed state.

2. The protective casing as claimed in claim 1, characterized by an alphanumeric keypad (5).

3. The appliance as claimed in claim 1 or 2, characterized in that the interface has a plug connection (6) for connecting the input and/or output device (5) to the mobile communication appliance (2, 4).

4. The protective casing as claimed in claim 3, characterized in that the plug connection (6) is designed for connection to a standard input/output jack on a mobile radio (2, 4).

5. A set comprising a mobile communication terminal (2, 4) and a protective casing (1, 3) as claimed in one of the preceding claims.

6. A set, particularly as claimed in claim 5, comprising a mobile communication terminal (2, 4) and a protective casing (1, 3), where the protective casing has an input and/or output device (5) and an interface for transmitting signals between the input and/or output device (5) and the mobile communication terminal (2, 4), characterized in that the mobile communication terminal has a control device which, when the mobile communication terminal is connected to the protective casing'"'"'s interface, automatically puts a displayed item on a display on the mobile communication terminal into a desired orientation with respect to the protective casing'"'"'s input and/or output device.

7. A set, particularly as claimed in claim 5 or 6, comprising a mobile communication terminal (2, 4) and a protective casing (1, 3), where the protective casing has an input and/or output device (5) and an interface for transmitting signals between the input and/or output device (5) and the mobile communication terminal (2, 4), characterized in that the mobile communication terminal has, on a front side, a first display for use with an integrated input device on the mobile communication terminal and, on a rear side, a second display for use with the protective casing'"'"'s input and/or output device.

8. The set as claimed in claim 7, characterized in that the mobile communication terminal has a changeover device which, when the mobile communication terminal is connected to the protective casing'"'"'s interface, automatically changes over from the first display to the second display.
