Abstract
PURPOSE: To increase the repetitional durability of a wire, by hanging an end of the double-looped wire on a swivel pulley for dividing the tension onto two wires.
CONSTITUTION: Developing rollers 3, etc. of a developing device 2 built in a copying machine are vertically reciprocated by a vertical driving mechanism 138. This mechanism 138 is so composed that when a winding pulley 141 is turned forward by means of a motor 140, a wire 142 is wound round the pulley to lift the roller 3 and when the motor 140 is reversed, the roller is shifted downward. The wire 142 is double-looped to make two apparent wires 142a, one end of which being fixed in front of the pulley 141 and the other end being hanged on a swivel pulley above a stay 117.
