PROBLEM TO BE SOLVED: To provide a display mechanism for performing multiple adhesion of a plurality of soft magnetic substances on a display substrate by a magnetic attraction force of a magnet, the display mechanism having increased the number of multiple adhesion of display pieces compared with a conventional one.SOLUTION: The present superposition type magnetic adhesion display mechanism is configured such that, on the surface of a display substrate A having a sheet-like magnet 2, which is a flat-plate substrate 1 subjected to multipolar magnetization, adhered thereto, soft magnet films (display pieces) B are adhered in multiple layers by the leakage magnetic flux of the sheet-like magnet 2 of the display substrate A, and magnetic force reinforcing sheet-like magnets C subjected to double-side multipolar magnetization between the same polarities as the magnetic sheet 2 of the display substrate A are adhered in multiple layers on the surface of the soft magnetic film B when the soft magnet films B are adhered in multiple layers to or almost to the possible limit, so as to form a magnetic circuit 6 between the sheet-like magnet 2 of the display substrate A and the magnetic force reinforcing sheet-like magnets C to obtain a strong magnetic attraction force. The leakage magnetic flux of the surface of the magnetic force reinforcing sheet-like magnet C allows the soft magnet films B to be adhered in further multiple layers and the repetition of the adhesion, which enables much further multiple adhesion. |
