摘要： PROBLEM TO BE SOLVED: To propose a body of rotation driving mechanism free from speed fluctuation and realize an image formation device capable of performing print operation with high accuracy and high resolution. SOLUTION: Periodical fluctuation due to eccentricity in a body of rotation or the like is represented by a continuous repetitive function, and the waveform in reverse phase thereto is used as a driving command value for a driving means. Thus, smooth rotation is accomplished, and such control as to cancel out fluctuation is carried out. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a small optical writing device capable of performing high-precision optical writing, and an image forming apparatus. SOLUTION: A photoconductor/exposure-integrated device as a drum type is rotated clockwise at a constant speed. Residual toner, which adheres onto a surface of a photoconductor 1, is removed by a cleaner 5, and an electrifier 4 uniformly imparts a charging load to a surface of a photoconductor layer 1 in a main scanning direction, and brings about an electrostatically charged state. A light-emitting layer 10 exposes the photoconductor layer 1 from an inside in a light-emitting area 20, and forms a latent image on the photoconductor layer 1. The latent image, which is formed on the photoconductor layer 1, is toner-developed by a developing device 6, and turned into an obvious image by the adhesion of the toner to the latent image. A toner image, which turned into the obvious image on the photoconductor layer 1, is transferred onto a recording medium 8 by a transfer device 7. Since this eliminates movement between an exposure point and an imaging point in the light-emitting area 20, a deterioration in image quality, caused by the movement, is prevented.

摘要： PROBLEM TO BE SOLVED: To book-bind and sell a costomized book in accordance with specifications demanded by respective consumers. SOLUTION: A bookbinding instruction terminal 2a provides a GUI which supports an order procedure of a purchaser such as selection of book design, setting of a work structure or the like and transmits set contents on the GUI to a book database server 1. Thus, the book database server 1 retrieves a data base which registers cover data, writing data or the like and transmits the retrieval result (the book data, cover picture data, background pattern picture data, price information and so on) to a printer device 3a with a bookbinding function as the bookbinding information. The printer device 3a with the bookbinding function prints and binds the ordered book on the basis of the bookbinding information or the like transmitted by the book database server 1, and also executes processing for proceeding book reception by the purchaser smoothly.
