<p>PURPOSE:To improve efficiency of housing, simplify arrangement, and achieve reduction of size, by controlling a cartridge housing rack with use of rotation angle detector means for moving it in rotation and positioning it to a target position in the captioned autochanger for a microfilm system. CONSTITUTION:When a drum type cartridge housing rack 21 is turned normal direction (a) or reverse direction (b), position plates 321-328 traverse in succession exposure light of a second photointerrupter 31. Hereby, a control unit counts cartridge taking out of first through eighth rack trains 251-258, and successive facing as well as passing the conveying mechanism 40 thereof, and further retrieves a designated cartridge housing rack train and a rack stage, and stops its operation. An SL device 33 is actuated simultaneously with interruption of power supply to a motor M1, whereby the pin 35 is projected to engage with stopper slider plates 341-348 for permitting those plates to accurately be stopped and fixedly mounted on the respective rack trains 251-258. Hereby, efficiency of housing a cartridge can be improved together with miniaturization of the equipment and simplification of its structure.</p> |
