OPTICAL FIBER SCANNER, ILLUMINATION DEVICE, AND OBSERVATION APPARATUS

摘要

The present invention improves ease of assembly by preventing variations in the assembly of an elastic part to a fixed part. Provided is an optical fiber scanner (10) equipped with: an illuminating optical fiber (11) for guiding illuminating light and emitting same from the tip; an elastic part (21) that is obtained from an elastic material and fits with the illuminating optical fiber (11) on the base end side of the tip; multiple piezoelectric elements (23), which are fixed on the side surface of the elastic part (21), are polarized in the radial direction of the illuminating optical fiber (11), and is for oscillating the illuminating optical fiber (11) via the elastic part (21) by an alternating voltage being applied in the direction of polarization; and a fixed part (25), which has a fitting hole for fitting the elastic part (21) at a position that is shifted toward the base end from the piezoelectric elements (23) of the elastic part (21) and is for supporting the illuminating optical fiber (11) in a cantilevered fashion via the elastic part (21) that has been fitted in the fitting hole. The elastic part (21) and the fixed part (25) have marks (31, 33) representing the position of assembly when the two are fitted with each other.
