<p>PURPOSE:To give no shocks when a film feeding speed is inverted and switched, by providing a control means which turns off driving up to a prescribed speed or lower on a basis of detection of a film speed detecting means. CONSTITUTION:A carrier of a micro roll film 7 switches the film feeding speed by selective depressing operation of keys 2-6 on an operation panel 1. The device detects the running speed of the film 7. A speed detecting mechanism 8 a control circuit which has a function to control driving to the turn-off state until the running speed of the film 7 is lower than the prescribed speed on the basis of the detection signal of the mechanism 8 are provided. The film 7 is guided from a supply reel 10 to a pressing roll 11 and a pair of idler rolls 12 and 13 and passes-between compressive glass plates 14 and 15 and is wound up around a reel 17 by a winding motor 16.</p> |
