Beschreibung
Zusammenfassung:	The device detects the movement of the drive belt by detecting rotation of a rotary element of the electric operating drive for the shutter shield via a cooperating sensor device. The rotary element is provided by a non-ferromagnetic deflection roller (17) containing at least one ferromagnetic and/or permanent magnetic element (25) providing a magnetic field effect detected by the sensor device for providing a corresponding signal. Pref. the sensor device is provided by a Hall element or a photoresistor controlled by a magnetic field.
