Claim:
A production method of electronic parts for pressing and filling a plastic material into a work piece positioned horizontally, said production method comprising the steps of: positioning the work piece having one side in a horizontal position with one side directed upward; overlaying a perforated plate having a through hole pattern passable by said plastic material on one side of said work piece; allowing a roller connected to a rotating machine to wait in a horizontal position in the vicinity of said perforated plate; feeding said plastic material to the peripheral surface of said roller by rotating said roller by said rotating machine; moving said roller along the upper surface of said perforated plate, while allowing the peripheral surface of said roller to approach the upper surface of said perforated plate, and at the same time, rotating said roller by said rotating machine in a somersaulting direction to a moving direction to which said roller moves; and pressing a squeegee supported along the peripheral surface of said roller to said perforated plate by a reactive force of the torque by which said rotating machine rotates said roller.
