Abstract: A method of magnetizing a magnetic sheet, said method able to magnetize a roll sheet conveniently at a high speed and stably including the steps of bringing a cylindrical permanent magnet having N-poles and S-poles multipolar-magnetized alternately along its circumference into contact with one surface of a long magnetic sticking sheet having an axis of easy magnetization oriented in a sheet longitudinal direction so that the sheet longitudinal direction is orthogonal to a shaft of the permanent magnet and multipolar-magnetizing the magnetic sticking sheet along the axis of easy magnetization by rotating the cylindrical permanent magnet due to the magnetic sticking sheet being rolled up, wherein the angle of contact of the magnetic sticking sheet fed to the cylindrical permanent magnet is made 45° or less, and a magnetization apparatus used for the method.

Abstract: A magnetic sticking sheet comprising a non-magnetic base and a magnetic layer formed on the non-magnetic base by coating a magnetic coating material containing ferromagnetic particles and a binder, the magnetic layer having a thickness of 0.03 to 0.10 mm, oriented longitudinally to give a squareness ratio of 80 to 90%, and multipolar-magnetized longitudinally; the sheet having a total thickness of 0.08 to 0.25 mm and flexibility for rolling; the magnetic layer having a surface magnetic flux density of 35 to 100G; and the sheet having a magnetic sticking force, required for removing a magnetic sticking sheet fixed magnetically on a magnetic surface via the magnetic layer while keeping the magnetic surface and the sheet parallel, of 0.4 to 0.9 gf/cm2.

Abstract: An image stabilizing optical device including an optical system having a first lens located on an object side and a second lens located on an imaging lens side. The first lens and the second lens are opposed to each other with a small space defined therebetween. Opposed surfaces of the first lens and the second lens have the same curvature. The image stabilizing optical device further includes a rotating mechanism located on the same center of curvature of the first and second lenses, for moving the second lens independently in two perpendicular axial directions in a plane perpendicular to an optical axis of the optical system; and a shake detecting mechanism for detecting shakes in the two perpendicular axial directions. The optical system is located in front of an imaging lens of an imaging device in proximity to the imaging lens. The rotating mechanism is driven according to a result of detection from the shake detecting mechanism to control an optical path of light incident on the optical system.
