Abstract
In a camera which includes a magnetic head which writes into and/or reads from a magnetic storage portion provided on a film while the film is conveyed. A magnetic head is positioned to stay away from a film when the film is conveyed without being exposed, such as during pre-winding, and is positioned to contact the film when the film is conveyed one frame after an exposure. Such positioning operation is drivingly connected to film-conveying operation by a simple mechanism.
Claims15
A camera in which a magnetic head writes into and/or reads from a magnetic record carrier provided on a film, comprising:
- film-conveying means for conveying the film;
- restricting means for restricting a relative position between the magnetic head and the film edge and which is shiftable between a restricting position and a non-restricting position, wherein said restricting means, when in said restricting position, contacts the film edge during the conveying of the film so as to regulate the relative position between the magnetic head and the film edge and, when in said non-restricting position, is maintained out of contact with the film edge during the conveying of the film;
- and
- controlling means for maintaining said restricting means at the restricting position and prohibiting the shift to the non-restricting position during the operation of said magnetic head.
A camera in which a magnetic head writes into and/or reads from a magnetic record carrier provided on a film, comprising:
- film-conveying means for conveying the film;
- restricting means for restricting a relative position between the magnetic head and the film edge and which is shiftable between a restricting position and a non-restricting position, wherein said restricting means, when in said restricting position, contacts the film edge during the conveying of the film so as to regulate the relative position between the magnetic head and the film edge and, when in said non-restricting position, is maintained out of contact with the film edge during the conveying of the film;
- and
- controlling means for shifting said restricting means between the restricting and the non-restricting positions.
A camera, comprising:
- a head unit which writes into and/or reads from a record carrier provided on a film, said head unit being shiftable between a recording position and a non-recording position;
- film-conveying means having a first mode and a second mode, said film-conveying means in its first mode conveying the film in a first direction and in its second mode in a second direction, which is opposite to the first direction;
- and
- controlling means being coupled with said film-conveying means, said controlling means maintaining said head unit in the non-recording position when said film-conveying means is in its first mode and the film is being conveyed in the first direction, and said controlling means maintaining said head unit in said recording position when said film-conveying means is in its second mode,
- wherein the operation for exposing one frame of the film and the operation for conveying one frame of the film are performed repeatedly when said film-conveying means is in its second mode.
