发明名称 One piece transparency mount with spring transparency restraint
摘要 A slide mount has a frame defining a transparency receiving cavity and a transparency inlet for inserting a transparency into the transparency cavity. A spring capable of imparting a compressive spring force in the transparency receiving cavity is connected to the frame away from the transparency inlet. The spring engages a transparency inserted into the transparency receiving cavity to retain the transparency in the cavity by a compressive spring force.
