ABSTRACT:
A rotational operation mechanism for a DJ apparatus enables smooth rotation to be achieved using a simple configuration. A rotational operation mechanism has a base, a display window member fixed onto the base, a ring member positioned on the display window member and holding a plurality of rotatable balls, and a rotation operation portion positioned on the ring member and operated by an operator. Mutually facing surfaces of the display window member and the rotation operation portion are provided with grooves that have substantially the same diameter as the ring member. The ring member is sandwiched between the display window member and the rotation operation portion such that the plurality of balls are received in the groove of the display window member and the groove of the rotation operation portion, and the ring member is rotatable in a peripheral direction. One of the rotation operation portion and the base is provided with magnets and the other of the rotation operation portion, and the base is provided with metal portions at positions facing the magnets.
