Claims

[Scope of utility model registration request]

In a plate eyepiece unit having a frame attached to a microscope, an eyepiece attached to the frame, and a reticle rotatably supported by the frame, the reticle is held at its outer periphery. and a holding frame having two or more contact surfaces on its outer circumferential surface that are formed into a substantially annular shape and have different diameters and are spaced apart from each other by a predetermined distance in the axial direction; a holding frame support mechanism that supports the frame in a directionally immovable manner; and contact portions that are rotatably and axially movably supported by the frame and can come into contact with respective contact surfaces of the holding frame. Each of these contact parts is equipped with a holding frame rotation drive mechanism in which only one of the contact parts is in contact with the corresponding contact surface and the driving force of the contact part can be transmitted to the holding frame. Shaped eyepiece unit.
