Claims

[Scope of utility model registration request]

The large diameter side of the eyepiece lens barrel, which has a narrowed part continuous to the large diameter part, is fixed to the main body, various mechanisms such as an automatic correction mechanism are provided in the large diameter part, and a focusing plate frame is installed in the narrowed part. The focus plate adjustment screw is screwed into the narrowed part to make it adjustable.
The large-diameter portion of the eyepiece-side lens barrel is surrounded by an outer cover tube whose one end is attached to the main body, forming a gap, and the narrowed portion of the eyepiece-side lens barrel is rotated toward the open end side of the outer cover tube. The eyepiece is surrounded by an inner cover cylinder which is movably attached to the eyepiece by forming a space therebetween, and has an adjusting screw operating hole formed at a position corresponding to the head of the focusing plate adjusting screw in the inner cover cylinder. 1. A focus plate adjusting mechanism, characterized in that an eyepiece is attached to a frame attachment part, and the operation hole is configured to be able to be closed by a protective cover that is detachably attached to an inner cover tube.
