PROBLEM TO BE SOLVED: To suppress positional shift of light beams resulting from thermal deformation of a housing and to improve assembling workability.SOLUTION: A fixing mechanism 300 of an optical scanning device, which emits light beams for scanning and is fixed to outer frames F1, F2, includes: penetration holes 103-105 formed on the frames F1, F2; protruding pins 100-102 which are provided to both ends of the housing 200 and can be inserted into the penetration holes 103-105 formed on the frames F1, F2; and a biasing means 106 which biases the housing 200 in one direction. |
