Abstract : The patent relates to apparatus for sensing the size of a loop of film and more particularly to loop sensing apparatus which is used in conjunction with a film scanner in such a manner that a scanning cycle will not commence until there is sufficient film available in the loop to complete a full cycle. An object is to provide a novel loop sensing apparatus. Another object is to provide a loop sensing switch which is of simple design and which comprises fewer moving parts than prior conventional loop sensing devices.
