Title:
OPERATING MEMBER AND ELECTRONIC DEVICE
Document Type and Number:
Japanese Patent JP2020160906
Kind Code:
A
Abstract:
To reduce a size and improve a durability of an operating member which generates a click feeling.SOLUTION: A sub dial 50 of a camera 100 is comprised of: a rotatable dial operation unit 501; a multi-pole magnet 505 that can rotate integrally with the dial operation unit 501 and has a plurality of magnetic poles in a circumferential direction; and a rotatable movable member 507 having a first magnetic pole portion 507a and a second magnetic pole portion 507b. The first magnetic pole portion 507a has a portion that generates a magnetic field in a direction in which an angle formed by a moving direction becomes an obtuse angle; and the second magnetic pole portion 507b has a portion that generates a magnetic field in a direction in which an angle formed by a moving direction is an obtuse angle. When the dial operation unit 501 is operated so that the multi-pole magnet 505 rotates in a direction in which an attractive force is weakened from a state in which the attractive force is acting between one magnetic pole of the multi-pole magnet 505 and the first magnetic pole portion 507a, the movable member 507 moves so that an attractive force is generated between another magnetic pole of the multi-pole magnet 505 and the second magnetic pole portion 507b.SELECTED DRAWING: Figure 5
