Described is an input and output device for inputting or outputting data of an electronic equipment. The input and output device is designed for being detachably mounted to the electronic equipment in at least two different positions. The input and output device features a first contacting arrangement which, independent of the selected position in the mounted state of the input and output device on the electronic equipment, electrically comes in connection with a second contacting arrangement present on the electronic equipment. In one embodiment, orientation of the device may be varied, thereby enabling it to be coupled to a receiver by a bayonet connection and with a set of contacting arrangement engaging the second contacting arrangement in any orientation. Moreover, described are an operating and display module, as well as to a combination of an electronic equipment and an input and output device that can be detachably mounted thereto.
