The communication device has an input device, an output device, and a housing surrounding one of the input and the output devices. The housing has a mounting plate (1) attached with a lower casing (5). A sensor detects a relative change of position of the plate and the casing. The sensor detects a horizontal change of position from the plate to the casing. The sensor detects a distance between the plate and the casing. The casing is moved opposite to the plate around a horizontal axis. The housing has a latch (6) that prevents a vertical relative motion between the plate and the casing. |
