れか１項に記載の画像形成装置の読取装置。[Scope of Claim for Utility Model Registration] (1) A chart having a black part and a standard white part is provided directly on the glass surface of the edge of the document surface of the platen glass of the document holding table, thereby making alignment correction and shading correction possible. A reading device for an image forming apparatus characterized by: (2) A utility model characterized in that the alignment correction is a correction during writing by automatically correcting the output signal of a minute amount of deviation that remains after correction of the mutual positional deviation of each solid-state image sensor for color separation. A reading device for an image forming apparatus according to claim 1. (3) The scope of the utility model registration claim, characterized in that the alignment correction described in item 1 detects a positional deviation between the chart and the document, and automatically corrects the position of the image medium and the image at the time of writing based on the detected information. A reading device for an image forming apparatus according to item 1 or 2. (4) Any one of claims 1 to 3 of the claims 1 to 3 for registering a utility model, characterized in that the shading correction is to correct deviations in the outputs of each part of each image sensor, including insufficient peripheral light of the photographing lens. A reading device for an image forming apparatus according to section 1. (5) The chart has a linear band of a constant width in a color distinguishable from black or white in the long side direction of the platen glass plate, and a linear band of a constant width in the same color as the long side in the short side direction at right angles to the band. 5. A reading device for an image forming apparatus according to any one of claims 1 to 4, wherein a band is provided and the end margin is then finished in a standard white color.
