    • An exposure device includes a reference current generating unit generating a reference current for each image of respective colors, a photoelectric current generating unit generating a photoelectric current in response to a light amount of the light emitting element, a driving unit driving the light emitting element, a first controller, a drive voltage holding unit holding a drive voltage given to the driving unit, a second controller controlling the driving unit based on the drive voltage held, a comparison current generating unit generates a comparison current, a difference current generating unit generating a difference current, of each color, corresponding to a difference between the reference current of each color and the comparison current. The first controller compares a value obtained by adding the difference current of each color to the photoelectric current with the comparison current to control the driving unit so that the photoelectric current becomes the reference current.

    • The present invention relates to an electronic apparatus including a housing unit of which the angle can be varied by a rotation mechanism and is directed to improve the fixation precision of the housing unit that can be fixed at predetermined angles. The apparatus includes a supporting frame unit (movable arm unit), a rotation supporting unit (rotating module) installed on the supporting frame unit, a housing unit (movable housing unit) that is fixed on the rotation supporting unit and can be rotated by the rotation supporting unit, and a rotation locking mechanism that is installed away from the center of rotation of the rotation supporting unit and, when the housing unit is rotated to a predetermined angle, holds the supporting frame unit and the housing unit in a locked state.
