Abstract: PURPOSE: To execute the maintenance work of the inside of a core unit in a laminating state as multivision by providing a frame locking a screen with a detaching mechanism which can be operated from the front surface. CONSTITUTION: The screen unit 3 and the projection unit of the respective core units are loaded in a housing 2 through a slider unit 6. By the unit 3, the screen 8 is locked by using the frame 10. Then, a first lever 15 is pressed by a tool 51 and rotated counterclockwise. Besides, a second lever 16 is rotated counterclockwise so as to press the frame part 19 of the frame 10 forward. The coupling of a movable cam 41 and a fixed cam 42 is released and the unit 3 is pressed forward (in the leftward direction) because the moving piece 25 of the unit 6 is moved with respect to the fixed piece 30 thereof. Then, the unit 3 is removed from the housing 2 by putting a hand on the frame 10, drawing the unit 3 this side and detaching a stud 21 from the notched part 28 of the moving piece 25.

Abstract: PURPOSE:To align a substrate to be exposed and a photomask with high accuracy even when multiple exposure is performed by observing light which is reflected by the substrate to be exposed and photomask after being transmitted through a polarizing plate and then transmitted through polarizing plate again. CONSTITUTION:Light emitted by a light source 1 is transmitted through a half- mirror 2 to reach the photomask 12 and substrate 11 to be exposed as a body 10 to be observed, and its reflected light is reflected the mirror 2 and observed by an observation device 3. The polarizing plate 4 is arranged in the optical path between the mirror 2 and body 10 to be measured. The polarizing plate 4 transmit selectively the reflected light from the body 10 to be observed and removes selectively only the light by the peripheral edge part of a substrate-side aligning mark formed by exposing the photosensitive emulsion layer of the substrate 11 partially. Therefore, the quantity of the reflected light at the peripheral edge part of the substrate-side aligning mark as to the incident light to the observation device 3 decreases greatly as compared with the quantity of the reflected light at other parts. Then, the peripheral edge part of the substrate- side positioning mark in the recognized image on the observation device 3 becomes black and can be recognized clearly and distinctively from other parts.
