A film storage device for storing films fed by a feed system in a magazine includes a pressing mechanism, angularly displaced with respect to a direction in which a film is fed, for pressing the film into the magazine, a film feeder coupled to the pressing mechanism and angularly movable for forcibly delivering the film into the magazine along the direction, and a drive mechanism for moving the pressing means into the magazine. The film storage device also has a system for storing and displaying the number of films stored in the magazine, and also for detecting a mismatch between the types of the cassette and the magazine.

A cassette loading and unloading device for loading and unloading a cassette which typically accommodates an exposed film carrying image information includes a pair of guides for holding a cassette therebetween, the guides being relatively displaceable depending on the size of the cassette to be held therebetween, a cassette holder for displacing the guides to a position in which to open a lid of the cassette, while the cassette is being held by the guides, and a displacing mechanism for returning the cassette holder to an original position and allowing the cassette to be removed from the guides. The guides include a fixed guide and a movable guide, which are relatively movable to define a space therebetween that matches the size of a selected cassette.

Improvement in the device for enlarging and projecting a microfilm image is provided. The improvement is directed to an optical system acting as a magnification varying means and image rotation means as a united system. The optical system comprises a set of reflectors including three or more odd number of reflectors, magnification varying means for changing the length of the light path through the system thereby to vary the magnification of enlargement, and an image rotation means for rotation said set of reflectors to rotate the light delivering the enlarged image, said magnification varying means and said image rotation means being co-operatively associated with each other such that the light axis of the light getting out of the optical system is aligned with the light incident to the system. In case where the number of reflectors included in the optical system is three, individual reflectors united to constitute the reflector set are moved and/or rotated to vary the magnification of enlargement while satisfying the interrelationship indicated by .alpha.-.beta.+.gamma.=.pi./2 where .alpha., .beta. and .gamma. are angles of incident lights on respective reflectors. Also provided by this invention are link assemblies for moving and/or rotating individual reflectors to ensure that they move and/or rotate while always satisfying the interrelation essential for the required performance of the optical system.
