<p>PURPOSE:To execute alignment at a corner for a center type copying machine for aligning an original with the center of an original platen, by executing a converting arithmetic operation to a coordinate data on a photosensitive body from a prescribed coordinate of the original which has been controlled and placed in one corner, and a size of a copying form. CONSTITUTION:On an original platen 1, a scale is provided, and when an original 8 is placed by aligning it with an orthogonal corner member, a coordinate value of the original 8 is read through the scale. This coordinate value is inputted through a ten key 6, and when a set key 52 is operated, said value is stored in a RAM contained in a CPU. The CPU confirms a fact that a changeover switch 4 shoes a corner alignment, and calculates a coordinate on a photosensitive body by a converting arithmetic operation from a copying paper size through a sensor, and the coordinate value. Accordingly, even against a center type copying machine, an alignment of the original can be executed easily and exactly by executing a corner type alignment.</p> |
