Benefits of technology

The present invention is an optical reflecting device that improves mechanical strength by folding portions of each oscillation part. This allows for larger and higher frequency mirror motion.

Problems solved by technology

In this case, however, there is a problem that stress is focused on the folded portions of each oscillation part and thus crack or the like easily occurs.

first exemplary embodiment

[0024]Hereinafter, an optical reflecting device according to a first embodiment of the present invention will be described with reference to the drawings.

[0025]FIG. 1 is a perspective view illustrating the optical reflecting device according to the first embodiment of the present invention. As shown in FIG. 1, optical reflecting device 10 according to this embodiment includes fixed frame 11, one pair of first oscillation parts 12a and 12b, movable frame 13, one pair of second oscillation parts 14a and 14b, and mirror part 15. One-side ends of one pair of first oscillation parts 12a and 12b are connected to and held by the inside of fixed frame 11. Movable frame 13 is connected to and held by the other-side ends of one pair of first oscillation parts 12a and 12b to be pivotable around an S2 axis. One-side ends of one pair of second oscillation parts 14a and 14b are connected to and held by the inside of movable frame 13. Second oscillation parts 14a and 14b are disposed to be substan...

Abstract

An optical reflecting device includes a fixed frame, a pair of first oscillation parts, a movable frame, a pair of second oscillation parts, and a mirror part. One-side ends of the first oscillation parts are connected to the inside of the fixed frame. The movable frame is connected to and held by the other-side ends of the pair of first oscillation parts to be pivotable. One-side ends of the pair of second oscillation parts are connected to the inside of the movable frame and the pair of second oscillation parts are disposed to be substantially perpendicular to the pair of first oscillation parts. The mirror part is connected to and held by the other-side ends of the pair of second oscillation parts to be pivotable. The first oscillation parts have a meandering shape in which a plurality of straight portions and a plurality of folded portions are formed, and a stepped structure portion is provided in part of the folded portion.

Description

BACKGROUND[0001]1. Technical Field[0002]The present invention relates to an optical reflecting device used for a display apparatus or the like.[0003]2. Background Art[0004]Conventional optical reflecting device 1 is shown in FIG. 10. As shown in FIG. 10, conventional optical reflecting device 1 includes fixed frame 2, one pair of first oscillation parts 3 and 4, movable frame 5, one pair of second oscillation parts 6 and 7, and mirror part 8. One-side ends of one pair of first oscillation parts 3 and 4 are connected to the inside of fixed frame 2. Movable frame 5 is connected to and held by the other-side ends of one pair of first oscillation parts 3 and 4.
