Abstract
PURPOSE:To accelerate focusing by providing plural insert parts on a moving mechanism which changes the distance between an objective lens and an eyepiece and moving the moving mechanism by inserting selected operation members into the insert parts. CONSTITUTION:Three push buttons being the operation part are provided on a joint arm upper part which supports a mirror body. An objective lens frame 13 is interlocked with a sliding board 10 slidably attached to the joint arm. Three holes 16a-16c corresponding to the push buttons are provided on the positioning part 15 of a positioning board 14 which is slidably back and forth on the board 10. When a leg part of each push button provided with the slope of a guide part is inserted, both the board 14 and the board 10 are moved. In addition to that, when a rotating ring 8 is rotated, the board 10 moves along the board 14. Adjustment of many stages ranging from a short distance to a long distance is performed and a visible state is obtained by means of the rotating ring 8 by moving the objective lens corresponding to the operating position of the operation member.
