A magnetically permeable soft plastic sheet 5 such as vinyl chloride, which forms the bottom body 4, is laid on the top surface of the insulating sheet 3'' made of mica or the like. The required number of magnets 1 are positioned and placed at the required positions.At this time, the magnets 1 are attracted to the lower electrode 3' and are difficult to move, so positioning is easy.Next, a sheet of sponge 6 is placed on the top surface of the magnets 1. Further, the top surface of the sponge 6 sheet is covered with a soft plastic sheet 5' made of vinyl chloride or the like as the exterior body 7, and the upper electrode 8 is lowered from above to the surrounding area of the magnet 1 to cover the soft plastic sheet of the bottom body 4. 5 and the soft plastic sheet 5' of the exterior body 7 are welded together, and the periphery of the welded area is cut.When welding the soft plastic sheet 5' of the exterior body 7 to the soft plastic sheet 5 of the bottom body 4, In addition, the peripheral edge of the sponge 6 is pushed down to the outer periphery of the side surface of the magnet 1 together with the soft plastic sheet 5' of the exterior body 7, and when the fusing is finished, it tries to return to its original state due to its elastic restoring force, so that the exterior body 7 and The peripheral edge, which is the welding point to the bottom body 4, is lifted, and a slight gap is created between it and the suction surface.

に解決できる効果がある。(Operations and Effects of the Invention) First, since the paper leaf retainer with a built-in magnet is covered with an exterior body made of sponge and soft plastic sheet, it is not only soft and has an improved tactile sensation, but also allows the magnet to be directly , there is no risk of touching the sheet to be pressed and damaging it or leaving pressing marks, and in the manufacturing process, by pressing down the upper electrode with a bath cutting blade from above, the bottom body is made soft. The plastic sheet and the soft plastic sheet of the exterior body are high-frequency welded around the magnet with at least the peripheral portion of the sponge sheet compressed in the vertical direction by the pressing force of the upper electrode. After being melted around the welded area and releasing the pressure from the upper electrode, the periphery of the plastic sheet on the bottom is pulled upward by the restoring force of the compressed part of the sponge sheet to its old state and floats up. With this structure, the gap for inserting the tip of the paper leaf holder at the periphery of the paper leaf retainer with a built-in magnet can be constructed extremely easily, and the above-mentioned problems can be satisfactorily solved. effective.
