摘要： A scanning type projector for scanning an optical beam emitted from a laser light source has a collimator lens and a scanning device. A beam demagnifying and shaping prism is disposed between the collimator lens and the scanning device. The cross section of the beam that is elliptical is demagnified along the major axis of the ellipse such that the cross section of the beam is shaped. Thus, the cross section of the beam fits within the effective diameter of a deflecting mirror incorporated in the scanning device. The optical beam is reflected efficiently. A bright image can be projected. The resolution is improved by the beam shaping effect.

摘要： An image processing apparatus includes a read unit and a first correction unit. The read unit reads a document and generates multilevel image data from the document. The first correction unit corrects the multilevel image data contained in a first range predetermined as a color indicating a fluorescent color so as to move the multilevel image data contained in the first range to an outside of a print color range when at least a part of the multilevel image data is contained in the first range.

摘要： An optical pickup includes a light source, an objective lens, a diffraction grating that divides an optical beam reflected from a predetermined information layer, into a plurality of optical beams, and a detector having a plurality of photo-receivers to receive a plurality of optical beams. The diffraction grating has a predetermined region for dividing from a signal light beam a region including a central portion of a spot which the signal light beam will form on the diffraction grating. A distance from a central section of the detector to that of a spot center photo-receiver on the detector, the spot center photo-receiver being provided to receive the optical beams formed by division in a predetermined region of the diffraction grating, is equal to or greater than a spot radius of the unwanted light beams entering the predetermined region of the diffraction grating, on the detector.

摘要： An image reading device includes a transporter transporting a document to a reading position, a first corrector correcting a skew of the document by coming into contact with a leading edge thereof, a radiating unit radiating light to the document, an image-information acquiring unit acquiring image information of the document based on information of light reflected therefrom, a reflector reflecting the radiated light, a leading-edge detector comparing a quantity of light reflected by the reflector with a quantity of light reflected by the document so as to detect the leading edge, a skew-amount calculator calculating a skew amount of the leading edge, and a second corrector correcting a skew of the image information based on the skew amount. The device switches between the skew correction by the first corrector and the skew correction by the second corrector based on document information, the skew amount, or user's selection.
