ROTATIONALLY-OPERATED INPUT DEVICE |
摘要 |
A rotationally-operated input device includes the following elements: (a) a magnetized cylindrical rotary magnet; (b) an operating shaft having the rotary magnet inserted and held thereon; (c) an upper case and a lower case for sandwiching the operating shaft therebetween rotatably; (d) an insulating substrate for fixing and holding the lower case; (e) a detection element mounted on the insulating substrate, for detecting rotation of the rotary magnet in a non-contact manner; and (f) a fixed magnet for generating an attractive and repulsive force between the fixed magnet and the rotary magnet. This structure allows detection of a rotation state of the operating shaft and provides click-feeling at rotating operation, in a non-contact manner. Thus a long-life small rotationally-operated input device can be provided.
