Abstract

PURPOSE: To make possible accurate detection of sizes even if paper form objects are conveyed in a twisted state by providing timing generating photoelectric cells and projectors for measuring the lengths of shades respectively in plurality.
CONSTITUTION: Illuminating light sources 20a, 20b of both edge parts in the conveying direction of a paper form object 3, phto detectors 12a, 12b having a specified length LO in the direction perpendicular to the conveying direction of the object 3, timing generating photoelectric cells 11a, 11b which are disposed in the direction perpandicular to the conveying direction of the object 3 and detect that the object 3 has been conveyed, a means 24 which detects the length that the object 3 cuts off the illuminating light from the signals obtained from the phtoto detectors 12a, 12b through controlling of the cells 11a, 11b, are provided and the size of object 3 in the direction rectangular to its conveying direction is obtained by an arithmetic circuit 27 from the length signal obtainable by the means 24 and the length signal between the photo detectors 12a, 12b.
