Abstract

PURPOSE: To expand the capacity of the device on the whole and speed up the operation when using, by dividing the accommodation of information between the retrieval mechanism main body and a spare information file device, and constituting to communicate the two by means of a film transfer mechanism.
CONSTITUTION: A film selection mechanism 4 consists of a film housing carrier 1, projection optical system 2, and lighting optical system 3, and eight pieces, for instance, of this film selection mechanism 4 are disposed in the radial direction, and the luminous flux from each projection optical system 2 is introduced into a direction selection mirror 5 disposed in the central part of the entire device by means of a film retrieval optical system 6. Corresponding to each film housing carrier 1 of the film selection mechanism 4, a spare information file device 7 is arranged so as to constitute a cylindrical drum, and the loading and unloading of the film from a film housing body 11 mounted on the spare information file device 7 are carried out by a film transfer mechanism 12.
