PURPOSE: To reduce access time by conveying a cartridge to an insertion location on an extension line located upwardly of an axis by gripping the cartridge with a hand mechanism capable of vertical and longitudinal movements as well as turning in the captioned changer for use in a microfilm system.
CONSTITUTION: With a hand mechanism 76 facing to a desired rack by retrieving a required drum rack, a motor 5 is positively rotated to permit the hand mechanism 76 to advance, and then an SL device 79 is actuated by an operation signal from a photointerrupter 72 and cartridge detection signal 82 by a pin 85 to permit the cartridge to be gripped by means of hands 77, 78. The motor 5 is reversely rotated by a cartridge grip signal 82 to permit the hand mechanism 76 to go back from the rack. In succession, a standing and falling plate 64 is rotated around an axis, and the hand mechanism 76 is rotated, whereby the cartridge is adjusted to take an attitude thereof in accordance with a direction of cartridge insertion. Then, the cartridge is lifted and inserted into an insertion part. Hereby, access time can be reduced, and the captioned changer minimized.
