Abstract

A thin operation input unit in which a high sensitivity characteristic of a magnetic field sensor is effectively utilized. The operation input unit comprises a base (10), a printed board (20) mounted with push button switches (21 to 25) and Hall elements (29a, 29b) on its upper surface and integrally laid on the base (10), an operation member (50) composed of a metal ring (51) integrated with press projections (59a to 59d) and supported on the base (10) vertically movably on the printed board (20), and an operation dial (70) having on its lower surface a ring magnet (65) where N and S poles are alternately arranged and rotatably attached to the upper surface of the operation member (50). When the operation dial (70) is rotated, the variation of the magnetic flux of the ring magnet (65) isdetected by the Hall elements (29a, 29b) to detect the rotation direction. When the operation dial (70) is pressed, the push button switches (22 to 25) are operated by means of the press projections (59a to 59d) of the operation member (50).

Description

technical field [0001] The invention relates to an operation input device applicable to a mobile phone and a portable music player. Background technique [0002] At present, as an operation input device used in a mobile phone, there is, for example, a structure composed of the following members: a substrate; a printed circuit board on which a plurality of push button switches and magnetic field detection elements are mounted and stacked on the substrate; The operation board placed on the printed circuit board; the ring magnets alternately arranged with N poles and S poles are installed below and installed on the operation board in a freely rotatable manner. . Furthermore, the operation input device detects a change in the magnetic flux of the ring magnet by the magnetic field detection element and detects a rotation direction by turning the operation dial, and on the other hand, presses the operation dial to Push button switch is operated (refer patent document 1).
