A spectral colorimetric apparatus includes a housing which includes a side wall. An outer surface of the side wall is an adjustment surface capable of adjusting a position of a linear sensor by moving while attaching the linear sensor to the adjustment surface. The linear sensor is supported by the side wall of the housing while abutting on the adjustment surface and receives alight beam that is dispersed by a concave surface reflection type diffraction element and passes through an opening portion. The adjustment surface is parallel to a tangential line at a part of a Rowland circle of the concave surface reflection type diffraction element, through which a light beam received by the linear sensor passes.

Color image forming apparatus and scanning optical apparatus

A light deflecting device for deflecting a light beam comprises a rotational mirror having two reflecting surfaces for reflecting the light beam, a rotational mirror mounting portion, biasing means for urging the rotational mirror against the mounting portion, and driving means for rotating the mounting portion.

Light deflecting device

A laser beam printer having a deflector for deflecting a laser beam modulated in accordance with information to be recorded and a photosensitive member which is scanned by the deflected laser beam. A frame is provided to position both the deflector and the photosensitive member, the frame having a positioning portion for positioning the photosensitive member. The frame is mounted on a printer base, the frame being supported on the base at three points wherein one of the three points is located adjacent the deflector and the other two points are disposed adjacent the positioning portion of the photosensitive member.

Laser beam printer having three-point support system

An optical scanning device comprises a beam source unit having a laser source, and a housing on which the beam source is mounted. The housing accommodates optical components through which a laser beam from the beam source unit is applied to the surface of an object thereby to optically scan the object surface. The housing includes a base plate carrying the optical components and a side wall provided with a beam source mounting portion which enables the beam source mounting portion which enables the beam source unit to be mounted and demounted on and from the side wall by a vertical movement of the beam source unit. Alternatively, the side wall of the housing is provided with a locating portion which provides a locating surface parallel to the optical axis of the laser beam.
