Abstract:
An image scanning method comprising steps of:reflecting with a reflecting mirror an image light generated from an image of a medium arranged in a plane continuous in a main scan direction and in a sub scan direction, into a predetermined direction vertically intersecting said main scan direction; introducing said reflected image light to an image formation optical system so as to obtain an image formation at position of an image sensor consisting of a number of photo elements arranged in a direction parallel to said main scan direction; rotating said reflecting mirror pivotally supported by a rotary shaft parallel to said main scan direction so that a scan position of said image sensor on said medium is moved in said sub scan direction; and displacing at least one of said image sensor and said image formation optical system movably supported in a direction of an optical axis, in an interlocked state with said rotation of said reflecting mirror.
