Title:
ROTATION OPERATION DEVICE AND ELECTRONIC DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP2020136273
Kind Code:
A
Abstract:
To give click feeling in a compact rotary operation device, and improve durability.SOLUTION: A rotation operation device includes a magnet 251 that includes a rotation operation member 200 that is rotatable around a predetermined rotation axis, and that has a plurality of magnetic poles alternately magnetized and that rotates around a predetermined axis as the rotation operation member rotates, and a moving member 280 having first and second magnetic pole portions 280a and 280b and arranged to be movable relative to the magnet. When the rotation operating member is rotated in a state in which the attraction force acts between the magnet and the first magnetic pole, the magnetic pole of the magnet and the first and second magnetic pole portions are arranged such that repulsive force acts between the first magnetic pole portion and the magnet, and attractive force acts between the second magnetic pole portion and the magnet to move the moving member relative to the magnet.SELECTED DRAWING: Figure 6
