发明名称 Patient or visitor sign-in device
摘要 A sign-in device having a privacy screen provides a clipboard which supports a sign-in sheet for patent or visitor sign-in purposes. An elongated spool of substantially opaque flexible sheet material is held within a housing or support of the paper clamp. An elongated header bar is movably attached to a side margin of the board. An exposed end margin of the opaque material is attached to the header bar whereby movement of the header bar along the length of the clipboard causes the opaque material to be withdrawn from the spool forming the privacy screen which covers and conceals a selected portion of the sign-in sheet which includes the names and/or signatures of previously signed-in patients or visitors.
