The wafer box conveyer includes a chassis, a transverse moving mechanism, a longitudinal moving mechanism, a loading mechanism and a shock reduction mechanism. This protector plate is to be located on the furring strip so that its face panel is positioned to protect any service component located there behind from nails, screws or other anchors that may be subsequently driven into the wall. In an exemplary embodiment, the insulating film can be a polymer thin film of high dielectric constant, being made of a material such as polydimethylsiloxane or polyimide ; and the metal micro-thread is made of a high conductivity and high strength Ni\u2014Co alloy. The vibration reduction mechanism includes a shaft, a weight, a support member, and a urging portion.
