Rotary input device

A rotary input device, comprising:

• a substrate;
• a plurality of electrode patterns formed on the substrate;
• a rotary member configured to rotate relative to the substrate according to a rotation input operation;
• and
• a slide electrode held by the rotary member, the slide electrode including a plurality of contacts configured to slide on the plurality of electrode patterns, a state of connection between the plurality of contacts of the slide electrode and the plurality of electrode patterns switching in accordance with a rotation of the rotary member, the plurality of contacts including a first contact, and a second contact disposed closer to a rotation center of the rotary member than the first contact,
• wherein the plurality of electrode patterns include:
• a first electrode pattern configured to be connected to the slide electrode via the first contact when a rotation angle of the rotary member is within a first range from a reference rotation angle to a first rotation angle in a predetermined direction, the first electrode pattern being configured to be disconnected from the slide electrode when the rotation angle is over the first range as the rotary member further rotates beyond the first rotation angle in the predetermined direction, and
• a second electrode pattern configured to be connected to the slide electrode via the second contact when the rotation angle of the rotary member is within a second range from the reference rotation angle to a second rotation angle in the predetermined direction, the second rotation angle being greater than the first rotation angle, the second electrode pattern being configured to be connected to the slide electrode via the first contact when the rotation angle is within a third range from the second rotation angle to a third rotation angle in the predetermined direction, the third rotation angle being greater than the second rotation angle, and the second electrode pattern being further configured to be disconnected from the slide electrode when the rotation angle is over the third range as the rotary member further rotates beyond the third rotation angle in the predetermined direction.
