Rotatable-swingable input device and electronic apparatus equipped with the same
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.
1. A rotatable-swingable input device comprising:
a plurality of optical sensors disposed on a wiring board each of which comprises a light projecting section and a light receiving section that receives a light flux emitted from the light projecting section;
an operation member that enables a rotating operation and swinging operations in a plurality of directions;
a plurality of switches that are disposed on the same side of the wiring board where said optical sensors are arranged, each of the switches generating a signal when being pressed by a swinging operation of said operation member;
an elastically deformable holder that is disposed on the same side of the wiring board and holds said operation member so as to be rotatable and swingable; and
a click spring that contacts with a concavo-convex part disposed on said operation member to generate click feeling when said operation member is rotationally operated,
wherein said holder is provided with an inner annular part that holds said operation member so as to be rotatable and swingable in the plurality of directions, and an outer annular part that is arranged outside the inner annular part and has pressure parts each of which deforms elastically and pushes a corresponding switch among the plurality of switches when said operation member is swingingly operated in one direction among the plurality of directions, and
wherein said optical sensors are arranged at positions between said inner annular part and said outer annular part without overlapping with said click spring so as to interpose one of said switches when viewed in an axial direction of said operation member.
2. The rotatable-swingable input device according to claim 1 , wherein the outer annular part is provided with slide parts to which said operation member slides when said operation member is rotationally operated,
