Abstract:
A sheet conveying apparatus including, a conveying portion conveying a sheet; a rotation detection portion rotatably provided; a sensor portion detecting the conveyed sheet based on a rotational position of the rotation detection portion; a rotation transmission portion transmitting a rotational driving force to the rotation detection portion to rotate the rotation detection portion in a predetermined rotational direction after the rotation detection portion is rotated by being pushed by the leading end of the sheet; and an urging unit configured to apply an urging force to the rotation detection portion so that the rotation detection portion comes into contact with a surface of the sheet, thereafter the rotation detection portion is returned to a waiting position along with the passage of the rear end of the sheet through the rotation detection portion after the rotation detection portion is rotated by the rotational driving force of the rotation transmitting unit.
Abstract:
A sheet detecting apparatus including: a sheet detecting member having a plurality of abutment surfaces in a peripheral direction thereof, the sheet detecting member being rotated by a conveyed sheet abutting against one of the plurality of abutment surfaces; a detection portion which operates in association with the sheet detecting member; a sensor which generates a signal based on a position of the detection portion; and an urging portion which generates an urging force for positioning the one of the plurality of abutment surfaces of the sheet detecting member in a waiting position in which the leading edge of a sheet conveyed by a conveying portion abuts against the one of the plurality of abutment surfaces, and thereafter the urging portion switching the urging force to an urging force for positioning, in the waiting position, another one of the plurality of abutment surfaces against which a succeeding sheet abuts.
Abstract:
A progressive-power lens has one surface which satisifies the following expressions CY(DP)=CT(DP) CY(P)>CT(P) where CT(DP) denotes a vertical direction curvature at the distance reference point, CY(DP) denotes a horizontal direction curvature, CY(P) denotes a horizontal direction curvature at a point on the principal meridian which is located further on the near portion than the progressive start point, and CT(P) denotes a vertical direction curvature at the point.
Abstract:
A progressive-power lens includes an eyeball-side surface including a distance portion and a near portion having different values of dioptric power. An intermediate portion connects the distance portion and the near portion to each other. An object-side surface of the progressive-power lens includes a first region extending along a principal meridian and having a spherical shape having first curvature, a second region facing the distance portion and having a spherical shape having second curvature equal to the first curvature, and a third region located outside the first region and below the second region and having third curvature greater than the first curvature.

Abstract:
A method for designing an eyeglass lens includes: a basic value calculation step of determining a basic visualizing action index representing a visualizing action taken when a person who wears no eyeglasses or single-vision lenses looks at an object; a progressive value calculation step of determining a progressive visualizing action index representing a visualizing action taken when the person who wears reference progressive addition lenses looks at the object; and a lens designing step of enlarging the field of view as compared with that of the reference progressive addition lenses when the progressive visualizing action index shows greater head movement than the basic visualizing action index does, whereas enlarging an aberration region as compared with that of the reference progressive addition lenses when the progressive visualizing action index shows smaller head movement than the basic visualizing action index does.
