摘要:
An object detecting apparatus that detects an object including a magnetic body including: a detection signal acquiring unit that acquires a detection signal based on a magnetic signal; a disturbance source detection signal storage unit that stores a detection signal of a disturbance source that generates a disturbance component with respect to the detection signal; a determining unit that determines whether the detection signal acquired by the detection signal acquiring unit contains the disturbance component; an amplitude correction unit that corrects an amplitude of the disturbance source detection signal and generates an amplitude-corrected disturbance source detection signal; a disturbance component suppression unit that generates a determination signal by suppressing the disturbance component contained in the detection signal; and an object determination unit that determines whether the object is the object to be detected based on the determination signal.

An image forming apparatus includes an image reading unit that reads an image formed on a recording medium; a copy-prohibited medium detecting unit that detects whether a recording medium is a copy-prohibited medium; and a controller that controls to disable or inhibit copying of an image formed on a recording medium, when it is detected by the copy-prohibited medium detecting unit that the recording medium is the copy-prohibited medium, before the image on the recording medium is read by the image reading unit.

A control gate includes an exciting coil and a detecting coil. The exciting coil forms an alternating magnetic field in a passageway at an entrance to or an exit from an area where taking out or bringing in of an object is controlled. The detecting coil detects a change of the magnetic field when magnetic substance contained in the object generating a large Barkhausen effect causes magnetic inversion in the alternating magnetic field. The exciting coil is provided above the passageway and has a winding wire wound along a horizontal plane. The detecting coil is provided in a side part of the passageway and has a winding wire wound along a vertical plane which is parallel to a passing direction of the passageway.

A control gate includes a first exciting coil, a first detection coil, a second exciting coil, a second detection coil, a signal determination unit and an amplification factor setting unit. The first exciting coil forms a first alternating magnetic field in a passage. The first detection coil detects a variation in the first alternating magnetic field. The second exciting coil forms a second alternating magnetic field in the passage. The second detection coil that detects a variation in the second magnetic field. The signal determination unit includes a first amplifier which (i) amplifies a first detection signal of the first detection coil and (ii) determines a passage of the magnetic material based on the amplified first detection signal. The amplification factor setting unit sets a first amplification factor for the first amplifier based on a second detection signal of the second detection coil.
