A magnetic material amount detecting apparatus includes primary winding and secondary winding which are wound on a core having a reading section to which a to-be-detected medium is set close. A current is supplied to the primary winding and an output signal from the primary winding is adjusted by an A.C. current detecting section. Then, a difference between the output signal output from the primary winding and adjusted by the A.C. current detecting section and an output signal from the secondary winding is output as a signal indicating the amount of magnetic material which is present near the reading section.

Magnetic material amount detecting apparatus

A pair of cores are arranged such that first end portions thereof face to each other with a gap via a conveying path through which a medium to be detected passes. Coils wound at the first end portions of the cores, respectively, are connected in series to each other, thereby constituting a first coil. Coils wound at second end portions on a side opposite to the first end portions are connected in series to each other, thereby constituting a second coil. There are provided an exciting coil which generates a detection magnetic field passing the cores and the gap, and a convergent magnetic field generating unit which generates, in the gap, a convergent magnetic field for converging the detection magnetic field in a direction perpendicular to a direction in which the first end portions of the cores are connected to each other.

A pair of elastic strips are provided in order to hold sheet material to be measured in thickness. Each of the elastic strips includes of one or more elastic films. Ends of the elastic strips are supported by support portions, and the other ends of the elastic strips are provided with respective coils, opposed to push each other, and kept in contact with each other. When the sheet material is held between support portions, the inductances of the coils are changed and the thickness of the sheet material is detected as an electric signal representative of the changed inductance.

A pair of cores is arranged so that their respective first end portions are opposed to each other across a given gap with a transfer path (M) for the passage of a medium between them. Coils wound individually on the respective first end portions of the cores are connected in series with each other to form a first coil. Coilsandwound individually on second end portions of the cores are connected in series with each other to form a second coil. Coils wound individually on respective intermediate portions of the cores are connected in series with each other to form a third coil. A signal processing circuit is provided for AC-energizing the third coil to process a detection signal from the first coil and a detection signal from the second coil.
