である。A small mark 00 is provided at the center of the objective lens (1), and by moving the focusing lens (2) in the direction of the arrow, an image can be formed from #I (limit trace) to the small mark (II). The range of the automatic correction mechanism is as follows: When the automatic correction range (9) is displayed on the crosshair (7) 1- of the focusing plate (5) and the small mark 01> is imaged on the focusing plate (5), The above image formation is automatic sleeve i1-

４）は正常に作動して込ることが判る。The automatic correction mechanism (4) is equipped with a prism α4 (up to), and the small mark (11) is a small dot made of a vapor-deposited film located exactly at the center of the outer diameter of the objective lens (1) and on the focusing lens (2) side. The φ mark (Oυ) may also be attached to the front of the objective lens (1), so that it does not peel off easily. Until the measurement range is F, the small mark 0η is used as a check for the automatic correction mechanism (4) when it is imaged on the focus plate (5).In other words, the image of the small mark (B) is (5
) is within the automatic correction range circle (9), the automatic correction mechanism (
It can be seen that 4) is operating normally.
