Abstract
A waterproof mechanism of key of a handheld computer includes a rubber outer cover, a sheet body, and a back glue. The sheet body is dispose in the rubber outer cover to prop up and fix the shape of the rubber outer cover. A soft key circuit board is disposed in the rubber outer cover and the sheet body. Circuits of the soft circuit board pass through the sheet body and the back glue. One face of the back glue adheres to the sheet body, and the other face thereof adheres to the inside of a key base. The rubber outer cover is compressed to deform and be hermetically fastened in the key base. Through tight connection of the rubber outer cover and the key base and adhesion of the back glue, water and liquid cannot permeate into the key base, hence achieving a very good waterproof effect.
