Abstract
PURPOSE:To assemble a hinge device easily and also to open and close it smoothly, by providing a helical spring for energizing an opening and closing body in the opening direction, and a damping plate operated by a one-way clutch when the opening and closing body is operated in the closing operation. CONSTITUTION:Both shaft supporting pieces 12 of a turning frame body 10 are positioned between both shaft supporting pieces 7 and 8 of both fixed frame bodies 6, and a supporting shaft 15 is inserted into a spring force adjusting plate 20, a shaft supporting hole of the shaft supporting piece 7 of the fixed frame body 6, a helical spring 26, a shaft inserting hole of the shaft supporting piece 12 of the turning frame body 10, and a one-way clutch 31 provided on a damping plate 29. Subsequently, both ends of the supporting shaft 15 are held by a hook ring to prevent them from releasing, the supporting shaft 15 is coupled with a boss 14 of the turning frame body 10 by a cupling pin 18, and the damping plate 29 is placed between brake shoes 32, 33. In this way, when a document feeder unit 3 as an opening and closing body is opened, it is opened lightly by energizing force of the helical spring 26, and when the opening and closing body is closed, friction force of the damping plate 29 and the brake shoes 32, 33 operates on the weight of the opening and closing body itself, it is closed hastily and is performed smoothly without being damaged.
