ABSTRACT:
An electronic still single-lens reflex camera having an improved tracking device employing a simplified construction and having a lowered manufacturing cost. A head feed mechanism is operated in association with the operation of a drive unit which drives the image mirror of the camera in such a manner that the magnetic recording head is moved radially of the magnetic medium in association with the operation of the image mirror. The head mechanism includes a stage on which the recording head is mounted, a feed gear, a feed pawl, a tracking bar supporting the feed pawl and movable with the retraction of the image mirror from the image beam path, and a motion converting mechanism for converting the rotation of the feed gear into linear motion of the stage, the feed gear being turned through a predetermined angle by the feed pawl.
