Method and apparatus for turning over pages of book-original

An apparatus for turning over a page of a book-type original which is set with spread pages being arranged upward, said apparatus comprising:

• an original pressing means for pressing an original surface downwardly;
• an attracting and separating means for contacting with at least one portion of the spread pages and attracting and separating the spread pages;
• a holding means for the attracted and separated original;
• and
• a page housing means for housing the separated pages, said page housing means is adapted that a housing speed of the page is no less than a separation speed of the page.

An apparatus for turning over a page of a book-type original which is set with spread pages being arranged upward, said apparatus comprising:

• an original pressing means for pressing an original surface downwardly;
• an attracting and separating means, including a belt, for contacting with at least one portion of the spread pages and attracting and separating the spread pages;
• a means for holding the attracted and separated original;
• means for detecting a tension of the belt;
• and
• means for identifying originals for which is not possible to turn over the pages on the basis of the tension of the belt detected by said detecting means.

An apparatus for turning over a page of a book-type original which is set with spread pages being arranged upwards, said apparatus comprising:

• means for turning over a page including:
• a belt contacting with a surface of said spread pages of the original in the face of said spread pages, an electrode held in contact with a surface of said belt for forming an electric charge pattern on the surface of said belt and generating uneven electric fields on the surface of said belt,
• a voltage applying means for applying a voltage to said electrode in order to form the electric charge pattern,
• a belt moving means for moving the surface of said belt from one end of the spread pages to the other end thereof continuously in a direction of separating said surface from said book-type original while attracting said one of pages on said surface of the belt so that an uppermost page of said original contacting with said belt is attracted by the uneven electric fields generated on the surface of said belt and is separated from a next page of said original,
• a page stripping means for stripping continuously said attracted page separated from a next page of said original from said belt, and
• a supporting means for supporting said page stripped from said belt;
• and
• moving means for moving said means for turning over a page along a surface of said spread pages from one end of said original to the other end thereof.

An apparatus for turning over a page of a book-type original which is set with spread pages being arranged upwards, said apparatus comprising:

• an original placing base for placing the original set with spread pages;
• page contacting means for contacting with a surface of an uppermost page of the spread pages;
• an electrode contacting with a surface of said page contacting means and forming an electric charge pattern on the surface of said page contacting means for generating uneven electric fields on the surface of said page contacting means;
• a voltage source for applying a voltage to said electrode to form the electric charge patten;
• and
• a moving means for moving a contact face of said page contacting means contacting with the surface of the uppermost page of the spread pages from one end of the spread pages to the other end thereof, thereby to turn over the uppermost page of the spread pages attracted to said contact face of said page contacting means by said uneven electric fields generated on the surface of said page contacting means.
