Abstract
In a microfilm retrieval device, a frame which is at a position corresponding to its frame address is automatically retrieved and the object frame is projected on the screen of the reader. In such a device, the object frame must be accurately positioned at a positioning section irrespective of the types and size of microfilms and skew and pitch of frames. An arbitrary frame can be positioned and an accurate automatic retrieval can be realized even if no images are recorded in the reference frame or in the maximum address frames in both the row and the column, or if a microfilm is slanted in arrangement.
