A push pressure control device of a pickup roller is provided to secure a simple spring support structure by connecting left and right springs as one and to prevent fatigue load from being accumulated at the spring due to friction between coils by forming a gap between the coils of the spring. A push pressure control device of a pickup roller(110) is composed of a plurality of pickup rollers contacting to the upside of a bill in drawing the bills, in order to separate the bills one by one and a spring(120) for controlling push pressure applied to the bills by the pickup rollers. The spring comprises first and second springs(121,122) symmetrically disposed to apply uniform push pressure to the left and right sides of plural pickup rollers. |
