Abstract

Abstract An original holder plate for copying machines and a method for preparing said plate are provided. Said original holder plate comprises a molded base having a closed projecting rim, an original holding flexible layer partitioned by said closed projecting rim, an outer flexible layer covering said layer and a molded cover further covering said outer layer. To prepare said original holder plate, a closed projecting rim is made on a molded base, rubber or synthetic resin is poured into the space divided by said closed projecting rim to form an original holding layer, other rubber or synthetic resin is poured all over said layer to form an outer layer, a molded cover is mounted to cover said outer layer, and said molded base, said two layers and said molded cover are vulcanized and casted. A handle is made at one end of said original holder plate integrally, and said original holder plate is mounted to a copying machine with two protruding shafts embedded integrally on the other end of said original holder plate.
