ニツトの露光量調整装置。 In the exposure amount adjusting device for a lamp unit, which includes a plurality of light control plates for adjusting the exposure amount provided along the exposure opening of the unit case, a movable member that can freely move back and forth in the width direction of the exposure opening is arranged to adjust the exposure amount. A holding means is provided on the base in correspondence with each of the light plates and holds the light control plates individually and releasably, and is rotatable about an axis perpendicular to the plate surface of the light control plate with respect to each movable member. A first drive means that is freely provided and drives and rotates the holding means individually, and a second drive means that reciprocates the moving members individually, and for exposing a portion corresponding to each light control plate. It is characterized by comprising means for detecting the amount of light irradiated from the aperture, and further comprising a control means for driving and controlling the first and second driving means so that the amount of light detected by the light amount detecting means is within a set range. Exposure adjustment device for the lamp unit.
