摘要： A detector for detecting a position of a mark comprises: an image sensing device; an optical system which projects the mark onto an image sensing surface of the image sensing device; a pattern located in a position between the image sensing surface and an optical element located closest to a plane on which the mark is to be located, among optical elements forming the optical system, the position being optically conjugated with the plane; and a processor which calculates a position of the mark with respect to one of a position of the pattern and a position already known from the position of the pattern, based on a moire pattern formed on the image sensing surface by the mark and the pattern.

摘要： A slotter-creaser unit includes an upper creasing head and a lower creasing head. A protruding portion is arranged on a periphery of the lower creasing head in a circumferential direction. A first pressing portion and a second pressing portion having different lengths and different curvature radiuses in a width direction are arranged opposite to each other across the protruding portion and in an alternate manner in the circumferential direction.

摘要： An optical pickup device includes:a laser source for emitting, to an optical disk, a laser beam having a wavelength λ1 and a laser beam having a wavelength λ2, which is longer than the wavelength λ1; a light receiver, for receiving laser beams that are reflected by the optical disk;a beam splitter, for directing, to the light receiver, the laser beams reflected by the optical disk; andan astigmatism generation element, located between the beam splitter and the light receiver, for generating the laser beams to be used for focusing control, by designating as the front of the light receiver a focal point on one of the intersecting cross sections that include the light axes of the laser beams, and by designating as the rear of the light receiver, a focal point on the other cross section,wherein the astigmatism generation element is an optical element, which is like a Fresnel lens, whose step depth is substantially a natural number times either the wavelength λ1 or the wavelength λ2.
