Abstract

Disclosed are an operational input device and an electronic device using the same. Even if bearing load from large extraneous force, the invention can still ensure predetermined waterproofness. The operational input device operates an operational meter dial (60) supported on a printing substrate through rotation, and magnetic force sensors (26, 27) of the printing substrate are used for detecting magnetic field change resulted from the rotation of the operational meter dial (60). And, the printing substrate is installed on a base (10) which has annular ribs protrudingly arranged on the periphery of the upper surface, and is covered by an elastic plane waterproof component (40). Moreover, riveting bumps (73, 74 ) protrudingly arranged on the lower surface of an annular fixed part (70) are pressed into waterproof pressing holes (47, 48) on the elastic waterproof component (40) and are in riveted joint with the base (10), so that the operational meter dial (60) can rotate and may not fall off.

Description

technical field [0001] The present invention relates to an operation input device, in particular to an operation input device assembled in electronic equipment such as mobile phones, PDAs, televisions and video recorders. Background technique [0002] Conventionally, as an operation input device, as disclosed in Patent Document 1, for example, there is a rotary input device including a disc-shaped rotary operating element 10, and a rotary operating element 10 that supports and rotates freely. The housing member 11 that rotates ground, the circuit board 12 disposed opposite to the rotary operation member 10, the contact connection structure composed of the fixed contact 13 and the movable contact 14, and rubber is provided between the rotary operation member 10 and the circuit board 12. The rubber-like sheet 15 is equipped with a tilting pressing portion 42 that is tiltably supported relative to the circuit board 12 via a tilting support portion 49 on the rubber-like sheet 15...
