Document Type and Number:
Japanese Patent JP3598646
Kind Code:
B2
Abstract:
An auto document feeder (ADF) adjustment mode is set from an operation panel and a start key is pressed. An original is conveyed to an image reading unit by an original conveying apparatus, a scanner reads an original image and image data is generated. The image data is stored into image memory. By searching the image data stored in the image memory, two vertexes are detected. From the two vertexes, inclination to the standard original reading position is calculated, and also, dislocation in the main scan and subscan directions when the inclination is corrected is calculated. The inclination and the dislocation in the main scan direction are converted into real adjustment amounts and displayed on the operation panel. The dislocation in the subscan direction is sent to a CPU and then the CPU controls the original conveying apparatus so as to optimize the original-conveying distance.
