    Abstract: In a method of recognizing meandering of a web, with respect to the reference image data, one side 1A of a rectangular meandering recognition block Φ is set parallel to a printing traveling direction Y at a position where mA1 pixels of an output P(A) are located on one side of the one side 1A and mA2 pixels of the output P(A) are located on the other side thereof, and an opposite side 1B of the one side 1A of the meandering recognition block Φ is set parallel to the direction Y at a position where mB1 pixels of an output P(B) are located on one side of the opposite side 1B and mB2 pixels are located on the other side of the opposite side 1B. With respect to the test image data, a meandering recognition block Φ D having the same shape as that of the block Φ is set at a position corresponding to the block Φ set with respect to the reference image data. A difference ΔP(Φ) between a sum P(Φ) of output data of all pixels included in the block Φ and a sum P(Φ D ) of output data of all pixels included in the block Φ D is calculated. A difference ΔP(Φ n ) between a product of the output P(B) and a pixel count n of the block Φ in the direction Y and a product of the output P(A) and the pixel count n is calculated. A meandering amount and direction of the web are obtained on the basis of the absolute value and the sign of a quotient obtained by dividing the difference ΔP(Φ) by the difference ΔP(Φ n ).

    Abstract: A device for inspecting a printed board has linear image sensors. The image sensors read the image of the printed board on respective image reading positions (CAO, CBO, CA1, CB1), while scanning the image. A predetermined tolerance range (RY) for image-reading positions is previously determined so that the respective image reading positions are included in the tolerance range. Image signals obtained in respective image sensors are delayed by respective delay times. The respective delay times are previously determined in proportion to the deviations between the image reading positions and a reference position (RLY1), where the reference position is defined on the rear end (EPY1) or behind the tolerance range in the scanning direction (-Y). Through the delay process, all of the image signals are corrected to compensate for the respective deviations in the image reading positions.

    Abstract: An image reading system including a charge storing type image sensor drives a manuscript or an image sensor (1) in accordance with a driving pulse from a driving unit (2). A speed of the driving pulse from the driving unit is determined by a speed setting unit (5), depending on a change of a period of the apparatus scan. The driving pulse is stopped for a certain period of time, so that the difference in a speed of the driving pulse between the different apparatus scan periods is decreased.
