Abstract

A rotary input device comprising: a bezel portion that includes one or more pressing members; and one or more switch units, wherein each of the switch units is arranged to come in physical contact with any of the pressing members when the bezel portion is rotated, and generate an electrical on/off signal when the switch unit comes in physical contact with any of the pressing members.

First claim

What is claimed is:

1. A rotary input device comprising:
a bezel portion that includes two or more pressing members; and
one or more switch units, wherein each of the switch units is arranged to come in physical contact with any of the pressing members when the bezel portion is rotated, and generate an electrical on/off signal when the switch unit comes in physical contact with any of the pressing members,
wherein, the switch units comprises:
a housing;
a pin portion that is provided in the housing; and
a ball unit that is positioned above the pin portion.

2. The rotary input device of claim 1 , wherein any of the switch units comprises:
a shielding unit that is disposed between the ball unit and the housing, the shielding unit being arranged to press the pin portion when the switch unit comes in physical contact with any of the pressing members, and seal a gap between the housing and the ball unit.

3. The rotary input device of claim 2 , wherein the pin portion includes at least two pins that are arranged to be electrically connected or disconnected when the pin portion is pressed.

4. The rotary input device of claim 2 , wherein the ball unit comprises:
a ball arranged to come into contact with the pressing member; and
a ball housing arranged to receive the ball.

5. The rotary input device of claim 4 , wherein the shielding unit comprises:
a sealing plate disposed between the housing and the ball housing; and
a pressing portion that is provided in the sealing plate, and is arranged to extend towards the pin portion.

6. The rotary input device of claim 5 , wherein the shielding unit is made of at least one of silicone, urethane, or rubber.

7. The rotary input device of claim 2 , wherein the two or more pressing members are disposed on an inner surface of the bezel portion, and are spaced apart from one another.

8. The rotary input device of claim 7 , wherein:
at least one of the switch units comprises a first switch, a second switch that is disposed adjacently to the first switch, and a third switch that is disposed adjacently to the second switch, and
the first switch, the second switch, and the third switch are pressed one at a time by a given pressing member, when the given pressing member passes across the switch unit as the bezel portion is rotated.

9. The rotary input device of claim 8 , wherein:
the first switch, the second switch, and the third switch are pressed in a first sequence when the bezel portion is rotated in a clockwise direction, and
the first switch, the second switch, and the third switch are pressed in a second sequence when the bezel portion is rotated in a counterclockwise direction.

10. The rotary input device of claim 2 , wherein the ball unit is arranged to open or close the pin portion, when the ball unit is pressed as a result of coming in physical contact with the pressing member.

11. The rotary input device of claim 1 further comprising a housing, wherein the one or more switch units are disposed adjacently to each other along an edge of the housing.

12. The rotary input device of claim 11 , wherein each of the switch units is configured to generate a different sequence of signals according to a direction in which the bezel portion is rotated.

13. The rotary input device of claim 1 , wherein a rotational direction of the bezel portion is indicated by an order in which the switch units are pressed when the bezel portion is rotated.

14. An electronic device comprising the rotary input device of claim 1 .

15. The electronic device of claim 14 , further comprising:
a display unit; and
at least one processor operatively coupled to the rotary input device, configured to:
display a first interface on the display unit in response to a first signal from the rotary input device; and
display a second interface on the display unit in response to a second signal from the rotary input device.
