A document size detection device detects the size of documents (N) such as non-US currency and comprises a housing (33), a plate (35) mounted in the housing past which each document is moved, and LED photoelectric sensors (37,38) positioned along and across the plate (35) for sensing the size of each document and for initiating a signal indicating the length and width of each document. The signals are transmitted to a counting machine, which counts the sheets in response to said signal, and thereby counts the value of the sheets where the latter are currency notes. <IMAGE>
