Abstract
A multidirectional input device is disclosed wherein one rotary electric part and two first and second push-switches are operated by one operating member. In comparison with the prior art, a larger number of electric parts can be operated and thus the multidirectional input device is suitable for use in a portable electronic device for which various functions are required.
Claims5
A multidirectional input device comprising:
- a rotary electric part having a rotor;
- and
- an operating member having a shaft and an operating portion, the shaft being splined to a non-circular hole formed in the rotor, the operating portion being formed on an outer peripheral portion in an axial direction of the shaft and thicker than the shaft,
- wherein two first and second push-switches are disposed side by side in parallel with the axial direction of the shaft, an actuating member capable of performing a rotating motion and a sliding motion in the axial direction and capable of coming into abutment against the operating member is provided, the actuating member extending in a direction orthogonal to the axial direction, the rotary electric part is operated by rotation of the operating member, and the two first and second push-switches are operated through the actuating member by the sliding motion in the axial direction of the operating member.
