    The main objective of this paper is to reduce the timing of higher officials to sign in large number of same documents. Manual signing of documents adds time shortage in Public Work Department. Moreover, the manual process is time consuming and not suitable for signing a greater number of documents. The proposed model involves the arrangement of documents, positioning of facsimile, stamping the facsimile and take out the printed documents to distribute station. Thus, this model signs a greater number of documents within a short time. Pneumatic power is fruitfully utilized in this paper and the system is controlled by an Arduino controller. Positioning of facsimile is done by the lead screw arrangement with the help of sensors. The finished documents are then sucked by vacuum cup and taken out simultaneously. Our real time implementation helps them in unveiling such condition. The paper consists of two sections namely mechanical section and control section. The control section consists of Arduino controller and Relays. Arduino controller is used to control the DC motor and the relays are used to actuate the mechanical sections. The mechanical section consists of lead screw arrangement, pneumatic piston, suction cup and facsimile.
