ABSTRACT:
An installation structure is provided for an optical component, such as a collimator unit, with a control circuit board in an optical device, such as a laser scanning device. A L-shaped regulating plate is integrated to the collimator unit and the collimator unit is separated into an inside part and an outside part by the vertical wall plate portion of the L-shaped regulating plate. The vertical wall plate portion is abutted to the inner surface of the wall portion of a housing of the laser scanning device while the horizontal plate portion of the L-shaped regulating plate is seated on the flat bottom surface of a receiving recess formed on the bottom plate of the housing. A cut portion is provided on the wall portion of the housing, through which the outside part of the collimator unit is protruded out of the housing. The control circuit board is secured to the outside part of the collimator unit. The clearance between the cut portion and the outer periphery of the outside part of the collimator unit is closed by the rear surface of the vertical wall plate portion of the L-shaped regulating plate.
