摘要:
A carrying speed of a film is increased without generating scratches on the intermittently carried film. A film intermittent carrying device includes a film delivery mechanism; a delivering and accumulating mechanism accumulating the film and discharging the film in a short period of time; a winding and accumulating mechanism accumulating the film while simultaneously discharging in an amount corresponding to an amount of the film discharged in a short period of time; and a film winding mechanism taking-up the film constantly at a specified rate. The delivering and accumulating mechanism includes an upstream-side friction preventive unit not allowing a friction to occur between the film and the upstream-side movable roller. The winding and accumulating mechanism includes a downstream-side friction preventive unit not allowing the friction to occur between the film and the downstream-side movable roller.
