Abstract

An optical reflecting device includes a mirror part, a pair of joints, a pair of vibration parts, a plurality of driving parts, and a fixed part. Each of the joints has a first end connected to respective one the facing positions to each other on the mirror part and a second end opposite to the first end, and extends along a first axis. Each of the vibration parts has a central portion connected to the second end of respective one of the joints. A plurality of driving parts is disposed in each of the pair of vibration parts, and rotates the mirror part. Both ends of each of the pair of vibration parts are connected to the fixed part. The beam width defined as the length of each of the joints in a direction orthogonal to the first axis is greater than the beam width of each of the pair of vibration parts.

First claim

What is claimed is:

1 . An optical element comprising:
a mirror part; a plurality of beam parts connected to the mirror part; a fixed part connected to the plurality of beam parts; and a plurality of driving parts configured to rotate the mirror part around a first axis, wherein the plurality of beam parts includes;
a first beam part and a second beam part each connected to the mirror part, and each extending along the first axis; and
a third beam part and a fourth be…
