Claims (1)
露光スリツト装置であつて、前記光路を制限する
スリツトを囲むスリツト形成部材を弾性体にて形
成すると共に、スリツト長尺方向の両端部側部分
には、スリツト巾寸法を拡開縮閉させるスリツト
巾寸法調整機構を設けたことを特徴とする露光ス
リツト装置。 The exposure slit device is disposed in the middle of an optical path for illuminating and projecting an original image, and a slit forming member surrounding a slit that limits the optical path is formed of an elastic material, and a slit forming member is formed of an elastic material at both ends in the longitudinal direction of the slit. The exposure slit device is characterized in that it is provided with a slit width adjustment mechanism that expands, contracts, and closes the slit width.
