A rotatable-swingable input device that has high reliability at low cost and that improves operability. Optical sensors, an elastically deformable holder, and switches are disposed on a wiring board. A shading member has a plurality of shading parts that are arranged in a circumferential direction and pass a space between a light projecting section and a light receiving section of the optical sensor when an operation member is rotated. A click spring contacts with a concavo-convex part of the operation member to generate click feeling. The holder has an inner annular part holding the operation member and shading member, and an outer annular part having pressure parts each of which deforms and pushes one of the switches when the operation member is swingingly operated. The optical sensors are arranged between the inner annular part and outer annular part without overlapping with the click spring to interpose one of the switches.
