摘要

PURPOSE: An operation input device and an electronic device using the same are provided to detect the magnetic field with a magnetism detector and sensor by operating the handling dial supported in the upward of the print board. CONSTITUTION: The annular rib(11) is protruded in the circumferential side of the top surface part. The print board is mounted in the base. The base is coated to the elasticity waterproof material(40) having the flat type coating the base.
