Abstract
PURPOSE: To electromagnetically control, with small electric power, the pressure contact and spacing to the capstan of pinch roller, or engagement and disengagement to the shutter of release stopper, by using a permanent magnet or the like.
CONSTITUTION: As an electromagnet is used either M, which is a permanent magnet 2 provided in part of fixing yoke 1 made of magnetic material, or M', which uses fixing yoke 1 made of semihard magnetic material. Suppose said electromagnet M or M' is used for pressure contact controlling of the pinch roller. The both ends of a spring 11 are fitted to folding part 9a and arm part 9b of a pinch roller holder 9, One end of this spring 11a is also fitted to a pin 12 provided in a plunger 4 of electromagnet M or M'. when the plunger moves to the left in the drawing, the spring 11 is pushed in one end 11a to have spring force, which causes the other end part 11b engaged with the arm part 9b to turn the pinch roller holder 9 clockwise, so that the pinch roller is pressure-contacted to the capstan 6 through film 7.
