Abstract
PURPOSE: To control the tension applied to a film at a constant value with the use of a simple arrangement so as to prevent excessive slack by projecting arms for applying a tension to the film, on both sides of a pivot shaft, and by providing a roller at one end of the arm while a weight is provided at the other end thereof.
CONSTITUTION: A slack control device 200 for a film 1 allows a supply arm 109 having one end to which a supply pendulum roller 111 is journalled and a supply weight arm 201 having a removable supply weight 203 to project on both sides of the axis 103 of a supply film spool 106 as a center, and a tension is given by the weight 203. Similarly, even in a take-up film spool 107, an arm 113 to which a pendulum roller 115 is journalled and an arm 202 to which a removable weight 204 is attached, are projected so as to give a tension by the weight 204 so that a slack in the film 1 is eliminated, Thus, it is possible to control the tension at a constant value with as simple arrangement, and to aim at enhancing the resolution.
