<P>PROBLEM TO BE SOLVED: To provide a surface light source device where a photo conductive member can be fixed and held with sufficiently satisfactory fitting strength. <P>SOLUTION: The surface light source device comprises a circuit board 2, a light source 1, the photo conductive member 3, and a holder 7. The holder 7 has a positioning lock part 8 for positioning and holding the photo conductive member 3 and an engagement member 9 provided with an engagement claw 9B for fixing the photo conductive member 3 to prevent falling. The photo conductive member 3 has an engagement part 10 disposed and restricted by the positioning lock part 8, and a contact part 11 for stopping the photo conductive member 3 from oscillating is provided opposite to the circuit board 2. Consequently, while the engagement part 10 provided to the photo conductive member 3 is disposed and held at the positioning lock part 8 provided to the holder 7, the engagement member 9 provided to the holder 7 can holds the photo conductive member 3 to prevent falling, and the contact part 11 provided to the photo conductive member 3 is arranged oppositely in contact with the circuit board 2 to stop the photo conductive member 3 from oscillating. <P>COPYRIGHT: (C)2007,JPO&INPIT |
