Claims

[Scope of Claim for Utility Model Registration] (1) In a microscope illumination device that reflects a light beam from a light source by a reflecting mirror and illuminates a sample in any direction with a hollow cylindrical shape. a first transmission shaft formed, a second transmission shaft rotatably fitted in a hollow portion of the transmission shaft coaxially with the transmission shaft, and each handle portion provided at one end of the two transmission shafts. Thus, a coaxial handle member is formed, and the first transmission shaft is rotatably fitted into a hole provided in the wall of the apparatus main body so that the respective handle parts are outside the apparatus main body, and the first transmission shaft is rotatably fitted into a hole provided in the wall surface of the apparatus main body, The reflective mirror is tilted by a rotational operation of the handle portion of the first transmission shaft around a horizontal axis that includes a reflective surface and passes through a point on the reflective surface that abuts an optical axis in the illumination optical path. A tilting member is provided between the reflective mirror and the first transmission shaft, and the tilting member is provided between the reflective mirror and the first transmission shaft, and tilts the second transmission shaft around an axis that includes the reflective surface of the reflective mirror and is orthogonal to the horizontal axis. An illumination device for a microscope, characterized in that a rotation transmission member for rotating the reflection mirror by rotation of the handle portion is provided between the reflection mirror and the first transmission shaft. (2) In the microscope illumination device according to the above item (1), the second transmission shaft is also rotated by the rotation operation of the handle portion of the first transmission shaft, while the second transmission shaft is also rotated by the rotation operation of the handle portion of the second transmission shaft. An illumination device for a microscope, characterized in that a control member for making the first transmission shaft not rotate as a separate member is added to the device.
