摘要： A lighting unit (2) is provided with: LED arrays (220) in which light-emitting elements are positioned in an array in a main scanning direction; cylindrical parabolic mirrors (20) that project light emitted from the LED arrays (220) on an illumination region of an illuminated item; and a housing that houses or holds the LED arrays (220) and the cylindrical parabolic mirrors (20). Each cylindrical parabolic mirror (20) forms a shape in which a cylindrical paraboloid having curvature with respect to a sub-scanning direction (12) has been clipped by an axial plane that is perpendicular to the vertex of the cylindrical paraboloid in the main scanning direction (11). The LED arrays (220) are positioned so as to include the focal position of the cylindrical paraboloid in the light-emitting region, the central axis in the light-emitting direction being perpendicular to the axial plane.

摘要： An automatic paper feeding device for a document inputting device includes a pick roller (20), separating pads (68) each adapted to be brought into contact with the pick roller (20), a first pair of pick springs (58) and a pick spring (60). The first pair of pick springs (58) are disposed upstream the second pick spring (60) when viewed in a direction in which paper is carried. The first pair of pick springs (58) are disposed in areas widthwise outside the separating pads (68) in the axial direction of the roller, and the second pick spring (60) is disposed at the widthwise central position between the separating pads (68). The first and second pick springs (58, 60) are formed from a metal sheet integrally with each other as a spring unit, and the contact force of the first pair of pick springs (58) disposed upstream with the pick roller (20) is made smaller than that of the second pick spring (60) disposed downstream. The separating pads (68) are formed as a pad unit by branching a web (70) of a rubber sheet into a fork shape. The spring unit and the pad unit are supported together by means of a bracket (76) and presser member (78).

摘要： A reading unit (3) placed on the inner side of a U-shaped feed path (12) that feeds a document is formed such that the height-axis dimension of said reading unit decreases in a direction extending toward a side having a paper delivery tray (11) . Contact glass (20), a light source and a first mirror (24) are placed in the reading unit (3) at an end portion of the side having the paper delivery tray (11). Multiple reflecting mirrors (25, 26 and 27), a lens (28) and a photoelectric converter element (29) are placed further from the paper delivery tray than the first mirror (24) in the reading unit. This structure enables the reading unit provided in a document feeder to be more compact while ensuring the required light path length, and enables the entire document feeder to be more compact.

摘要： An apparatus is provided capable of guiding regular reflected light from a reading surface to a reflecting mirror when light is irradiated from two directions from light sources to the reading surface, and is suitable to read a gloss image. The light sources for irradiating light to the reading surface from the two directions of different angles are configured of a first light emitter and a second light emitter, a mirror reflecting surface for specularly reflecting light and a translucent surface for passing light therethrough being formed on the surface of a reflecting member for deflecting light from the reading surface to a predetermined reading light path direction, the first light emitter being arranged between the platen and the platen side surface of the reflecting member, the second light emitter being arranged at the back surface of the reflecting member so as to irradiate light on the reading surface through the translucent surface.
