ELECTRONIC APPARATUS WITH ROTATIONALLY-OPERATED MEMBER

摘要

An electronic apparatus which reduces the size of an operating ring in a radial direction while ensuring good operability using a click mechanism of the operating ring. A rotary member which rotates integrally with the operating ring has click holes formed on an inner peripheral side of concave portions and convex portions formed alternately in an outer peripheral portion. As the operating ring is rotationally operated, a ball is repeatedly engaged with and pulled out from the click hole to generate a click feel on the operating ring, and the concave and convex portions are repeatedly detected to detect a rotating direction and a rotationally-operated amount of the operating ring. The click holes, concave portions, and convex portions are formed in the rotary member such that the click holes and the concave portions are not aligned in a direction perpendicular to a rotation center of the rotary member.

主权项

1. An electronic apparatus comprising:
a rotationally-operated member; a rotary member configured to be able to rotate integrally with said rotationally-operated member, and comprise first concave portions and first convex portions that are formed alternately in an outer peripheral portion, and multiple click holes formed on an inner peripheral side of the first concave portions and the first convex portions in a circumferential direction; a click feel generating member configured to, in response to said rotationally-operated member being rotationally operated, repeatedly comes to a state of being in engagement with the click hole and to a state of being pulled out from the click hole to generate a click feel on said rotationally-operated member; and a detection unit configured to, in response to said rotationally-operated member being rotationally operated, repeatedly comes to a state of detecting the first concave portions of said rotary member and to a state of detecting the first convex portions of said rotary member to detect a rotating direction and a rotationally-operated amount of said rotationally-operated member, wherein the click holes, the first concave portions, and the first convex portions are formed in said rotary member such that the click holes and the first concave portions are not aligned in a direction perpendicular to a rotation center of said rotary member.
