Patent ID: 8524172

Claim:
A sensor device ( 45 ) for calibrating a staining device ( 20 ), the sensor device comprising: a coupling unit ( 46 ) configured to be attachable to a transport device ( 22 ) of the staining device ( 20 ) via a coupling member ( 44 ), the coupling member ( 44 ) configured to couple with the coupling unit ( 46 ) or a transport basket; and a sensor unit ( 48 ) carried by the coupling unit and adapted to detect the presence of movable components of the staining device ( 20 ); wherein the sensor unit ( 48 ) operates using acoustic, optical or tactile sensing techniques; wherein the sensor unit ( 48 ) includes a base element ( 49 ), a sensor lever ( 50 ) fixedly secured to the base element ( 49 ), and a sensor circuit ( 47 ) configured to detect a position of the sensor lever ( 50 ) or a force acting on the sensor lever ( 50 ).
