摘要 A document protecting device for holding a flexible document is disclosed comprising a first and a second member each having a transparent substantially planar central region interposed between end regions. Each of the end regions includes a protrusion entending outwardly relative to the planar central region. The first member is mounted relative to the second member with the protrusions defining end containers for receiving rolled portions of the flexible document with the planar central regions protecting an intermediate portion of the flexible document. The first and second members may be slideably mounted relative to one another for exposing a portion of the flexible document for making notations thereon. The first and second members may be substantially identical to one another with each of the members having a groove on one end thereof and a slide on the other end thereof. The first and second members are slideably secured to one another with the slides in the first and second members cooperating with the groove in the other of the first and second members. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not intended to be construed as a limitation on the scope of the claimed subject matter.
