Abstract

A sheet of exposed and developed instant-camera film is discharged from an instant camera and then inserted by the user into a film-holding structure on the back of the camera which very accurately positions the film sheet, such that upon removal and reinsertion of the film sheet into the holding structure the film sheet will always assume a predetermined position. The camera is provided with a multihead magnetic head unit mounted for reciprocating motion along a magnetic strip or coating provided at a marginal portion of the inserted film sheet. During first-direction travel of the head unit, one head records, and during second-direction travel of the head unit a different and differently located head records onto a further segment of the magnetic strip. After recording, the recorded information, e.g., spoken words identifying the subject just photographed, can be reproduced, and if desired erased.

Claims

1. In a photographic instant camera, a combination comprising a housing adapted to hold a film pack composed of a plurality of self-developing film sheets each having a margin provided with a magnetizable portion, said housing including a wall provided with a slot into which only said margin is insertable;

magnetic recording means in said housing and including a magnetic recording head mounted for movement along said slot and a film sheet margin inserted therethrough, for magnetically recording information onto said magnetizable portion of the respective film sheet; and

amplifier means for transmitting electrical signals to the movably mounted magnetic recording head.

2. In an instant camera as defined in claim 1, furthermore including drive means for moving the movably mounted magnetic head.

3. In an instant camera as defined in claim 2, the drive means being an electric motor.

4. In an instant camera as defined in claim 2, the camera being provided with a magnetic head unit provided with said magnetic head and with at least one further magnetic head differently located to track different portions of a magnetic track during travel of the magnetic head unit in respective directions and limit switch means for reversing the direction of travel of the magnetic head unit when the latter reaches a limit of its range of travel.

5. In an instant camera as defined in claim 1, said housing being provided with permanent magnet means for erasing information magnetically recorded on a sheet of film, the permanent magnet means being so located that a sheet of film can be drawn over the permanent magnet means to effect erasure of magnetically recorded information.
