ABSTRACT:
A camera includes a driving unit for rotating a film winding spool in a predetermined direction to wind the film or for rotating a spool in a loaded film patrone in a predetermined direction to rewind the film, a magnetic head pressing unit for pressing a magnetic head to a magnetic record section of the film interlocking rotation of the film winding or rewinding spool, an activating unit for activating the magnetic head pressing unit to retract from the film when an operation of the driving unit is stopped or when the spool is rotated in a direction opposite to the predetermined direction. The magnetic head is arranged in an inclined state against the film traveling direction such that a magnetic gap of the magnetic head contacts with the magnetic record section of the film at substantially right angle for a bent portion of the film by the contact of the magnetic head with the film.
