Rotary manipulation type electronic device

Abstract

The present invention provides a rotary manipulation type electronic device which permits one to obtain a feel of manipulations during rotational manipulations and produces lilting sounds of manipulations to thereby obtain an audiological sense of manipulations. The rotary manipulation type electronic device of the present invention has a base body with which a rotary body is rotatably combined. An operative element is disposed in such a way that movement of the operative element is restricted by the inside wall of a terminal leading portion of the base body and by leg portions of a leaf spring. Engagement portions engaging an uneven portion of the top surface of a flange portion of the rotary body protrude from the operative element. The leaf spring is brought into elastic contact with the top surface of the operative element.

Claims

1. A rotary manipulation type electronic device including: a base body having an opening portion in which a functional part is provided, the functional part generating an electric signal by contact with a sliding contact;a rotary body having the sliding contact on its bottom surface, the rotary body having an uneven portion on an outer periphery, the rotary body being rotatably supported to the base body;a leaf spring making elastic contact with the uneven portion; anda cover plate having the leaf spring on its bottom surface, the cover plate providing a cover over the opening portion of the base body, the rotary manipulation type electronic device comprising:an operative element having an engagement portion making engagement with the uneven portion,wherein the operative element is so disposed that movement in the direction of rotation of the rotary body and an outward direction going away from the center of rotation is restricted and that the operative element is pushed downward by the leaf spring vertically movably.

2. The rotary manipulation type electronic device of claim 1, wherein the leaf spring has a protrusive portion; andwherein the protrusive portion is in elastic contact with the uneven portion.

3. The rotary manipulation type electronic device of claim 2, wherein the protrusive portion and the engagement portion are in engagement at positions synchronized with a concave portion or convex portion of the uneven portion.

4. The rotary manipulation type electronic device of claim 2, wherein positions on the leaf spring at which the protrusive portions are formed are opposite to a position at which the leaf spring is in elastic contact with the operative element.

5. The rotary manipulation type electronic device of claim 1, wherein the operative element has a upwardly protruding protrusive portion; andwherein the operative element is disposed in such a way that the protrusive portions are vertically movably inserted in guide holes formed in the cover plate.
