Abstract: Scissors are provided wherein in a curved shape of cutting blades, assuming that when the scissors are opened, a distance between an intersection point where the left and right cutting blades intersect and a rotational center is Y, a line connecting the intersection point where the left and right cutting blades intersect and the rotational center is a rotation reference line B, a distance from the rotational center of the scissors to fixed points A on the left and right cutting blades is R (mm), an angle at which a line connecting the fixed point A on one of the cutting blades and the rotational center intersects the rotation reference line B is ? (rad), and an angle which is formed by tangents touching the fixed points A on the left and right cutting blades is X (rad), the shape of the cutting blades is expressed by a polar equation: R=Y*exp(?*Cot(X/2)).

Abstract: The invention is to provide a transfer tape which includes an opacifying layer having a high opacifying effect of a pattern, and according to the invention, there is provided a transfer tape 1 comprising a base material layer 2 and a coating film layer 7 and adapted to transfer the coating film layer 7 on to a surface of a transfer object by a coating film transfer device 50, wherein the coating film layer 7 comprises a pattern layer 42 on which an opacifying pattern shape is printed, and wherein a pattern shape of the pattern layer 42 is such that a plurality of alphabetical characters are arranged obliquely inclined relative to a longitudinal direction of the transfer tape, and the coating film layer 7 comprises an ink layer 32 where pigments are contained in a medium, the ink layer 32 and the pattern layer 42 being laminated in such a manner that the ink layer 32 is positioned on a front surface side, while the pattern layer 42 is positioned on a rear surface side of the coating film layer.

Abstract: An object of the invention is to provide a stamping device which can easily conceal personal information written or printed by stamping a pattern on a portion where the personal information is written or printed.
