PURPOSE:To assign images easily and quickly without using any special retrieval means by providing a low magnification projecting optical system which projects all the images of a microfiche on a screen and a high magnification projecting optical system which macro-projects only the one selected and assigned image on the screen. CONSTITUTION:A rectangular screen 2 which is projected with the images carried on a microfiche F loaded in this device is disposed in the upper part of the front face of a body 1. Also, an entire surface projecting system 3 for projecting the images over the entire surface of the above-mentioned microfiche F on the screen 2 and a one frame projecting system 4 for projecting the image of one frame of the microfiche F on the screen 2 are provided. In this case, the system 3 is of low magnifications and the system 4 of high magnifications. Since the desired images are selectively projected from all the projected images, the images are retrieved easily and quickly. |
