ABSTRACT:
An overlapping feed detection device in a machine for processing paper, money, slips, checks, or like sheets has propelling rolls driven by a motive power source and operating to propel the sheets and driven rolls disposed movably and spaced by a gate gap from the propelling rolls. The gate gap is for passage therethrough normally of a single sheet at one time. A holding mechanism holds the driven rolls in a nonrotatable state when one sheet passes through the gap, and release it to permit it to rotate when two or more sheets in overlapping state pass therethrough and widen the gap. A rotation detecting device detects the rotation of a rotatable structure.
