摘要： An optical scanner includes a single deflector to optically scan a plurality of target surfaces. The deflector is shared by all the beams from a plurality of light sources. The optical scanner includes photodetectors arranged to receive the deflected beams deflected. The beams traveling toward the deflector have an open angle in a deflecting rotation plane. A plurality of scanning optical systems are arranged to guide the deflected beams to different target surfaces. Each of the scanning optical systems includes at least two identical scanning lenses. At least one specific scanning lens in the scanning optical system is at a position rotated 180 degrees from a corresponding specific scanning lens in another scanning optical system. The specific scanning lens has a sub scan curvature on at least one surface with a shape asymmetrically varying from an optical axis toward both peripheries in the main scan direction.

摘要： PROBLEM TO BE SOLVED: To provide an image output apparatus which can output an image using a radio communication element, prevent information leakage to outside, and prevent interference in the apparatus. SOLUTION: The image output apparatus receives information from the radio communication element possible to perform radio communication, and outputs an image reflecting the information. The apparatus prevents leakage of information to outside of the apparatus, and prevents interference inside of the apparatus, by limiting transmission of information from the radio communication element, using means to limit communication time with the radio communication element, to give directivity to the radio communication element, and to limit a communication distance of the radio communication element, etc. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To be able to select and use desired information out of a plurality of information stored in a radio communication element, perform matching discrimination of authentication information of the radio communication element and inputted authentication information, permit to read, write, and rewrite information for the radio communication element, increase security performance, and at the same time, miniaturize the radio communication element, and expand the storage capacity. SOLUTION: An image input apparatus reads configuration information of RFID (Radio Frequency Identification) chip given to a draft by an information reading part 12, and sends to a control unit 50 when performing image processing of the draft read by an image reading part 11 in an image processor 13, and optimizing it. A control unit 50 offers the read composition information to the image processor 13 by instruction from a operation display unit 51, and image processing is made based on it. The draft information that is performed image processing and optimized, is carried out image forming processing in an image forming part 52. COPYRIGHT: (C)2005,JPO&NCIPI

A plurality of incident luminous fluxes to the deflector 5 from the plurality of light sources 1 have mutually spreading angles within the deflection and rotating surface. Let θ1max and θ1min be the maximum value and the minimum value of average incident angles with respect to the deflection reflection surface at the deflection and rotating surface, respectively, θ2 be the half image angle corresponding to an effective writing width, α be the tilt angle of the parallel flat plates with respect to the main scanning direction within the deflection and rotating surface.
