Having the magnetic quantitative detection sensor where the magnetic quantitative detection sensor, it possesses with the core

摘要

The magnetic quantitative detection sensor 10 where, fine magnetic pattern of suretsuto and the like of the paper leaf securely the detection possible magnetic quantitative detection sensor, being the paper leaf identification unit which uses the magnetic quantitative detection sensor device, and this magnetic quantitative detection sensor device, magnetic quantitative detection sensor device 5 the core body has with the exciting coil 12 which is laid out inside 11 which has the sensor surface 110 the void 16 aperture and void 16 even with when the multiple sensors are laid out rectilinear in conveying direction of the paper leaf, paper leaf 2 and faces moves and detects the magnetic pattern of paper leaf 2The having and core body 11 are laid out the direction W'ni multiple which is crossed in portable direction W of paper leaf 2 independently rectilinear, exciting coil 12 is laid out inside each void 16 of multiple core bodies 11.
