<P>PROBLEM TO BE SOLVED: To accelerate a film conveying speed without generating a scratch or the like on a film which is conveyed intermittently. <P>SOLUTION: A film intermittent conveying device includes a film drawing mechanism 22, a drawing accumulation mechanism 23 which stores and discharges the film in a short time, a winding accumulation mechanism 43 which stores a discharged amount of the film in a short time as soon as film discharge takes place, and a film winding mechanism 42 which always winds the film at a constant amount. The drawing accumulation mechanism is provided with first and second static rollers 24 and 25, an upstream-side movable roller 26 which moves through the intermediate part, and an upstream-side friction prevention means 27 which generates no friction between the film and the upstream-side movable roller. The winding accumulation mechanism 43 is provided with third and fourth static rollers 44 and 45, a downstream-side movable roller 46 which moves through the intermediate part, and a downstream-side friction prevention means 27 which generates no friction between the film and the downstream-side movable roller 46. <P>COPYRIGHT: (C)2013,JPO&INPIT |
