Halfway halt re-start control method null of manuscript

摘要

PURPOSE:To execute document read which scarcely causes disorder of a joint with out executing a back-operation of a document itself by executing the moving control of a carrier, in the case of executing a stop and a restart on the way of read. CONSTITUTION:In the case of stop in the course of document read operation, a document is stopped by through-down of document feed paper driving, and a carrier is moved by a distance obtained by adding a distance beta required for stabilizing the operation by document fixed read to a distance alpha by which a document advances by through-down in the advance direction of the document. Subsequently, the carrier is moved by a distance beta required for stabilizing the operation in the direction reverse to the advance of the document, and thereafter, read by a document fixed method is started, and by through-down and through-up in the case of document feed paper driving, the document reads the document by a distance corresponding to the sum of advance distances alpha, gamma and is stopped. Next, the carrier is moved in the advance direction of the document, stopped at a regular carrier stop position, document feed paper driving is executed by through-up in the advance direction of the document, and after it is completed, automatic feed paper read is started. In such a way, the overlap and omission of image read are not generated.
