ABSTRACT:
A film picture image viewing apparatus minimizes the effects of noise by prohibiting operation of an illumination device whenever a reading or a playback device is operated. The film picture image viewing apparatus includes a support substrate. The illumination device includes a discharge tube and a reflector. The discharge tube provides light when energized. The reflector is anchored to the support substrate and has a pair of oppositely-disposed ends with a receiving hole formed in each end. Each of the receiving holes is sized to receive the discharge tube in a manner to minimize thermal conduction from the discharge tube to the reflector after the discharge tube becomes energized.
