摘要 This specification discloses an original urging device for enabling an original to be well placed and supported on the original supporting carriage of a copying machine, a printing machine or the like. The supporting member for the original urging plate of the device has one end thereof pivotally supported. A point for taking the resilient force of a resilient member is provided at a point on the supporting member. During replacement of the original, the original urging plate may be made stationary within a predetermined range of angles facilitating the handling of the urging plate, in accordance with the rotated position of the supporting member and by the relationship between the moment produced by the gravity force acting to the supporting member and urging plate and the moment produced by the resilient force of the resilient member.
