ROTATABLE INPUTTING APPRARTUS

摘要

A rotatable input device is provided to enhance durability against an external impact. A wheel(11) is rotatable. A multi-pole magnetized annular magnet(13) is fixed at a lower side of the wheel(11), and is rotated as interworking with the wheel(11). A PCB(Printed Circuit Board)(31) includes hall sensors(35) mounted thereon to detect rotation of the magnet(13) and reception holes(37) into which the hall sensors(35) are at least partially inserted. A base(39) has the PCB(31) fixed on one surface thereof. A holder(15) is fixed on one surface of the base(39) and rotatably supports the wheel(11).
