Abstract
A distance defined by expression 2 is secured between the exciting coil and the protection cover. This not only prevents a magnetic field with a specific magnetic field intensity or higher from leaking to the outside but also reduces the effect on the circuits in the apparatus or optionally installed circuits (including a printer controller and a FAX controller).
