| Zusammenfassung: | The storage unit (100) receives its supply energy from an external device (200) in an electrically contactless way and transmits and receives signals as data signal and control signal from the and to the external device (200). Circuits (1-7) in the storage unit (100) are supplied by a direct-voltage supply (11a-11c), which is formed by a magnetic circuit with transformer coupling, when the storage unit (100) is in the vicinity of the external device (200). The input circuit (14b-14g) of the storage unit (100) has a photoelement, which is switched on by an LED (12b-12g) of the external device (200). The output circuit (12a) of the storage unit (100) has an LED. The data signal from the input circuit is written into and read out from the store (4), to be precise in dependence on a control signal of the control circuit (1-7). |
