ABSTRACT:
An image projecting apparatus for projecting an image recorded in a microfilm incorporated in a cartridge on a screen, for example, is furnished with a loading device which has a container storing a plurality of cartridges detachably attached thereto. The cartridges in the container are sequentially loaded at a prescribed position of a roll film carrier by a loading mechanism of the loading device and subjected to screening of a microfilm for retrieval of a desired image. The cartridge containing the microfilm which had undergone the screening is extracted from the prescribed position and returned to the container by a discharge mechanism. The discharge mechanism returns the cartridge loaded at the prescribed position via a path independent of the path used by the loading mechanism for moving the cartridge. The loading mechanism is provided with a set bar for extracting a cartridge from the container and a front surface part for locating the extracted cartridge at a prescribed position of the roll film carrier and loading it. The front surface part is disposed freely movably between an opening position for retaining the cartridge extracted by the set bar and a shutting position for loading the cartridge. The direction of a cartridge in the container is different before the cartridge is extracted by the loading mechanism and after it is returned by the discharge mechanism.
