INPUT DEVICE FOR A PORTABLE ELECTRONIC APPARATUS

摘要

An input device having sufficient countermeasure against static electricity is disclosed. The input device includes a touch pad as an operation-input part that is movably supported above a metal base plate. The operation-input part includes a pad plate to receive an input operation, a board plate stacked below the pad plate to detect an input operation to the pad plate, and a resin housing plate stacked below the board plate. The base plate has an upper face, on which a protruding piece is disposed so as to be inserted between the board plate and the housing plate and come into contact with a ground line as a conductive part provided at the board plate.
