发明名称 Reading material support
摘要 A stand for reading material or sheet material comprising a back support, and a pair of side supports hinged to said back support. A reading material support member is provided between said first and second side supports. First means comprising pins are provided on said support member for attaching said rear end of said support member to said first and second side supports. Second means are also provided on said support member for attaching said front end of said support member to said first and second side supports, said second means comprising pins mounted on a movable bar. A track is provided to guide the pins mounted on the movable bar so that the distance between the pins of said first means and the pins of said second means can be varied to change the angular orientation of the support member with respect to the back support. The reading material support can also be removed so that the stand can be collapsed.
