Abstract

PURPOSE: To enable accurate detection regardless of surrounding environments and object of detection, by opposedly providing displacement detecting parts having magnetic sensors at both sides of a sheet blank between opposedly provided magnetic field generating parts, and detecting the displacement by means of the deviation output.
CONSTITUTION: Excitation coils 1, 2 and a detecting coil 5 are housed in outer cases 7, 8, which are integrated by means of a joining member 9. The space between the excitation coil 1 and the detecting coil 5 should be a vacant area for feeding sheet blanks. That is, while sheet blank not illustrated is not supplied in the detecting space, the magnetic fields generated between the excitation coils 1, 2 are balanced, and the output of the detecting coil 5 is zero. When the sheet blank enters the detecting space, the magnetic flux generated from the excitation coil 1 is cut off. Since the magnetic fields are alternating magnetic fields, an output appears in the detecting coil 5. As a result, accurate detection is possible regardless of the environments and other conditions.
