Abstract: The invention presents a roll-sheet type display device for use at a booth or sales counter of small retail shop, window of retail shop, or outer wall of a building, being capable of displaying very easily without requiring huge installation work, and exchanging advertising and decorating means easily and at low cost. A display device 1 has a display sheet 14 showing printed advertising or decorating display object rolled on a roll 13, for forming a display object by unrolling and stretching by the roll 13, in which one part of the display sheet 14 is detachably attached to the roll 13.

Abstract: An object of the present invention is to provide a method of forming display objects on a magnet sheet and a magnet sheet formed with display objects by this method, wherein display objects with good visibility can be formed on a magnetic attachment surface and the display objects formed on the magnetic attachment surface are not transcribed on the subjected surface even though the magnet sheet is exposed to high temperature heat in the magnetization state and the magnetization state continues long time. A method of the present invention comprises of steps of process-forming mirror images 2 of display objects such as characters and figures on a surface of a rotating roll 1 by closing up minute pores by a laser process; and transcribing desired display objects 5 such as characters and figures on a magnetic attachment surface of a magnet sheet 4 by pressing the heated rotating roll to the magnetic attachment surface 4a.

Abstract: A magnet sheet 3 with a thickness of 0.05 to 0.15 mm is formed by molding a material obtained by adding magnetic particles to a synthetic resin material into a sheet and multiple pole magnetizing one surface of the sheet to form alternate N and S poles on that surface. A printing sheet 2 with a thickness of 0.05 to 0.15 mm, constituted by a paper sheet such as a high quality paper sheet or a coated paper sheet or a synthetic paper sheet or a synthetic resin film, is bonded to the non-magnetized surface of the magnet sheet 3. A magnet display sheet 1 , which has a thickness of 0.1 mm to 0.3 mm, is thus obtained, and it is capable of being printing on with a usual home or office copier or printer.

Abstract: A non-magnetic case 3 made of acrylic acid or like synthetic resin has a case body 3a, a lid 3b and a right hexahedron shape. The case body 3a has a substantially spherical accommodation space 3c in which a spherical magnet body 2 having paired N and S poles arranged in a uni-axial direction is sealed together with oil or a like transparent liquid having a high specific gravity and also having a considerably high viscosity to provide buoyancy to the magnet body 2 and facilitate the rotation thereof with a lubricating action. The clearance between the magnet body 2 and the wall surface of the accommodation space 3c is set to be small such that the magnet body 2 can be rotated smoothly. The case 3 with the magnet body 2 therein is applicable to combination toys such as toy blocks and puzzle sets or various attracting articles having mutual attraction requirement. The thickness of a central portion of each side wall of the case is reduced to facilitate the attraction of the magnet bodies to each other.
