LIGHT MEASURING APPARATUS

PROBLEM TO BE SOLVED: To provide a light measuring apparatus capable of obtaining a wide measuring area while avoiding the weight and cost increase of the apparatus. SOLUTION: A sample 10 is placed on a table 3 projected to the outside of a casing 1, and when the table 3 is driven by a drive mechanism 4, the sample 10 is stored into the casing 1 together with the table 3. At this time, a door 5 laterally energized by a constant load spring 33 is moved to the left together with the table 3 to close an opening 11 in a light shielding position where the door 5 abuts on the casing 1, thus securing a light shielded state in the casing 1. When the table 3 is further slid to the left, the door 5 cannot be moved together with the table 3 because it already abuts on the casing 1. The door 5 is thereby energized to the left by the constant load spring 33 to maintain the light shielding state of closing the opening 11 in the light shielding position. COPYRIGHT: (C)2009,JPO&INPIT
