Abstract

PURPOSE: To obtain an automatic opening-closing device of simple structure by opening and closing an original press member by shifting the center of gravity of the original press member by reciprocally moving a weight body.
CONSTITUTION: Front surface 1a of main duplicator body 1 is that opposing to an operator, original platen glass 2 is provided on the top surface of main body 1, and rod materials 4a and 4b are inserted, being vertically slidable, into guide members 3a and 3b provided to duplicator 1 at two rear positions of glass 2. To tips of rod materials 4a and 4b, bearing members 5a and 5b are fixed and on shaft 6, box-shaped press member 7 is supported while it can be opened and closed over glass 2. Inside of press member 7, miniature reversible motor 9, pulleys 11'14, wire 15, and weight body 16 are provided. Motor 9 is driven to feed weight body 16 backward and as weight body 16 moves near shaft 6, the center of gravity of press plate 6 is shifted backward from shaft 6 to open press plate 7. As weight body 16 is moved forth to the contrary, press plate 7 is automatically closed.
