ABSTRACT:
A device for managing a retractable sheet that is wound on a roller by the action of a spring that may be extended by pulling on the exposed edge of the sheet wherein the device is used for printing messages thereon or for obscuring the view of nearby items. The device is easily changeable for multiple uses as the roller containing the sheet is separable from the main unit, allowing reuse of the more complex and expensive components of the device. A brake on the device prevents the spring from unwinding when the roller is removed. A damping mechanism limits the retraction speed of the sheet, which the damping mechanism being disengaged when the sheet is being pulled out. A cover is provided to obscure the main part of the unit and to prevent tampering. A unique slot configuration allows for easy, tamper-resistant installation of a header card. A pull tab is made of inexpensive components and is designed to allow for easy placement of a graphic label.
