PROBLEM TO BE SOLVED: To prevent dust from adhering to a photodetector, and also prevent dust from floating on an optical path. SOLUTION: A baffle 30 for basic imaging which prevents stray light from entering a CCD is arranged inside a case. The baffle 30 for basic imaging includes a receiving plate 30a, and a baffle plate 30b preventing the stray light from entering the CCD. An opening 30e through which photographing light entering the CCD passes is formed on the baffle plate 30b. A non-reflection layer 39 preventing reflection is formed on the front surface 30c and the back surface 30d of the baffle plate 30b. A recess 30f is formed on the receiving plate 30a. The recess 30f is coated with grease 15. A plating projection 80 is peeled from the non-reflection layer 39 and becomes the dust, due to vibration when launching an earth satellite. The peeled plating projection 80 is adsorbed by the grease 15, so that the dust does not adhere to each photographic lens and each CCD. COPYRIGHT: (C)2011,JPO&INPIT
