Deceleration manner null of the manuscript discharge speed in the automatic manuscript

摘要

PURPOSE:To secure the superior stacking performance without generating the page deflection or broken document even in the high speed paper discharge, by switching the discharge speed to a previously set low speed at the time point for the passing in the length obtained by subtracting a certain length from the length of a document, after the start of the detection for the discharged paper. CONSTITUTION:After the start of the detection for a discharged paper by a paper discharge sensor S3, the discharge speed is switched to a previously set low speed by a speed change device at the time point for the passing in the length obtained by subtracting a certain length from the length of a document. Therefore, even if the distance between a paper discharge roller 19 and the sensor S3 for a discharged paper is short, the speed can be switched to the low speed at a constant position from the rear edge of the document, and the stable stacking performance can be obtained. Further, since speed is reduced at the constant position from the rear edge of the document, always superior stacking performance can be obtained even if the paper size is different, and transaction for the document having a large size can be carried out efficiently.
