Abstract
A film retrieving apparatus for retrieving a desired frame in a film has an optical device for projecting images recorded in the frames of the film, a moving device for moving the film along a plane orthogonal to the optical path of the optical device, image detecting device for putting out a signal when it detects that no image is present in a frame, a control device for stopping the film when each frame of the film has been placed in the optical path of the optical device and for controlling the moving device so as to move the film in a set time after the stoppage of the film, and an inhibition device for inhibiting a frame in which no image is present from stopping in the optical path for the set time by the signal put out from the detecting device.
Claims7
An apparatus for retrieving a desired frame in micro-fiche having a plurality of frames arranged in rows and columns, comprising:
- optical means for projecting an image recorded on a frame placed at a projection position;
- a carrier for holding the micro-fiche, said carrier being movable in horizontal and vertical directions with respect to the projection position;
- moving means for moving said carrier;
- detecting means for detecting whether or not an image is present on the frame of the micro-fiche;
- and
- control means connected to said detecting means for controlling said moving means such that when said detection means detects that an image is present on a frame of a selected row or column, said carrier may be stopped for a set period of time, and when said detection means detects that no image is present on the frame, a top frame in the next row or column may be placed at the projection position.
