Title:
DIAL OPERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/1998/016941
Kind Code:
A1
Abstract:
When a plate spring (22) rotates together with a knob dial (18) when the dial (18) is operated, the spring (22) is bent, because the spring (22) is pressed by the three corner sections of a cylindrical section (17a). When the three corner sections of the cylindrical section (17a) get over the spring (22) and new three faces are engaged with the spring (22) thereafter, the rotation of the dial (18) is controlled. Since the pressing direction and bending direction of the spring (22) are the same and the resistance to rotation of the dial (18) is reduced, the operating feeling of the dial (18) becomes lighter.
