Abstract
A sheet handling apparatus to perform predetermined processes for a recorded sheet comprises: a processor to process a sheet which is output from a sheet output unit; a sensor to detect a carrier speed of the sheet; and a controller to perform predetermined processes on the basis of the sheet carrier speed detected by the sensor and sheet carrier speed data transmitted from the sheet output unit. The processor has a carrier to carry the sheet output from the sheet output unit and then stores the sheet carried by the carrier into storage units. The controller compares the sheet carrier speed detected by the sensor with the sheet carrier sheed data transmitted from the sheet output unit and outputs a warning signal to display the result of the comparison when the former speed is deviated from the latter speed by a value above a predetermined value. In this manner, the abnormality of the sheet carrier speed is correctly detected and the occurrence of the abnormality of the carrying operation of the sheet such as sheet jam or stay jam can be prevented.
