摘要
An adjustable sensor for detecting marks or "blips" on a strip of microfilm. The sensor includes a pair of individually adjustable sensing modules separately adjustably mounted on a mounting plate. Preferably the modules are magnetically mounted to the plate. Each sensing module includes magnet means and an electronic circuit encapsulated within a housing and an arm for adjusting the position of the housing on the mounting plate. A detector, preferably a fiber optic wand, is connected to the electronic circuit and partially encapsulated within the housing. The fiber optic wand extends outwardly of the housing to detect the blips on the microfilm.
