ABSTRACT:
A metered film holding device in a camera comprising a metered film holding element supported to enter a film perforation in a metered filmstrip to substantially prevent unintended movement of the filmstrip, is characterized in that the metered film holding element is a ball supported to roll in place continuously in contact with the filmstrip when the filmstrip is advanced in the camera. The ball has a diameter greater than a maximum dimension of the film perforation in order to be able to roll only partly into the film perforation.
