ABSTRACT:
A miniaturized and inexpensive sheet sensing device which is easy to control and simple in construction and makes it possible to reliably sense one circulation of the sheet. A sensing member whose tip end is reciprocatingly displaceable in the direction of stacking of documents is disposed from the top face side to the bottom face side of the documents. At this time, the sensing member is bent and the tip end thereof passes along the side face of the document. In this way, at an initial stage of the conveyance of the document, the sensing member is disposed on the bottom face side of the stack of documents and at this time the sensing member becomes substantially linear, whereby the tip end thereof abuts on the bottom face of the stack of documents. In such a state, the conveying operation is repeated. A sensor senses that the sensing member has passed through the top face side and thereby senses that the conveying operation of the document has made its one circulation. The movement range of the sensing member becomes narrowed with the result that the one-circulation sensing unit can be miniaturized.
