摘要： The present invention relates to an optical scanning device in which a light beam is incident twice on a deflective reflecting facet and its object is to reduce curvature in scanning line trail or make the curvature substantially zero, or correct scanning line displacement due to the curvature in scanning line trail. Two stationary plane mirrors (13, 14) are disposed to face a deflective reflecting facet (11) which can be rotated about its rotational axis (12) such that a light beam (a1) being incident on and reflected from the deflective reflecting facet (11) is reflected by the two stationary plane mirrors (13, 14) sequentially. The reflected light beam (a3) is incident on and reflected by the deflective reflecting facet (11) again. Assuming that a plane being parallel to the rotational axis (12) and including the light beam (a0) which is first incident on the deflective reflecting facet is an incident plane, the central ray of an emergent light beam (a4) when the emergent light beam (a4) after the second reflection by the deflective reflecting facet (11) is on the incident plane and a straight line as the central ray of a light beam being projected on the incident plane when the deflective reflecting facet (11) is revolved by the maximum rotational angle are set substantially parallel to each other.

摘要： In order to measure a characteristics of a light beam which is repetitively deflected by a light scanning device within a first range in a first direction at a first velocity, there is provided a plate formed with at least one slit extending in a direction angled from the first direction and having a constant width. The plate is moved within the first range in the first direction at a second velocity which is sufficiently lower than the first velocity. A peak value of an optical power of light passing through the slit every time is detected when the deflected light beam crosses the slit being moved, thereby obtaining peak values at plural positions in the first direction. The peak values are displayed on a screen collectively in such a manner that positions on the screen correspond to the positions in the first direction.

摘要： An optical scanner emits a light beam in accordance with an image forming signal and deflects the light beam in a first direction. A scanned face is adapted to be scanned by the deflected light beam to form a scanning line while being moved in a second direction perpendicular to the first direction, thereby forming a latent image thereon. A virtual scanned face is defined as a plane including the scanning line and orthogonal to an optical axis of the optical scanner. The shape of a beam spot formed by the light beam incident on the virtual scanned face is approximated to an ellipse. The scanned face is inclined from the virtual scanned face so as to rotate about the scanning line, in accordance with an inclined angle of an major axis of the ellipse from the second direction on the virtual scanned face.

摘要： The present invention relates to a light deflective optical system without necessity of use of a plane mirror of which width is narrow, which can prevent variation in pitch of scan lines even with projecting or sinking of a deflective reflecting facet and can prevent a deflective light beam from twisting. The light deflective optical system has at least one deflective reflecting facet 11, capable of being revolved or swiveled about the rotational axis 12, and two stationary plane mirrors 13, 14, disposed to face the deflective reflecting facet 11, wherein a light beam a1 incident on and thus reflected at the deflective reflecting facet 11 is reflected successively at the stationary plane mirrors 13, 14 and this reflected light beam a3 is again incident on and reflected at the deflective reflecting facet 11. Assuming as an incident plane as a face containing a light beam a0 to be first incident on the deflective reflecting facet 11 and being parallel to the rotational axis 12, the light beam a0 to be first incident on the deflective reflecting facet 11 passes through a space 15 between the stationary plane mirrors 13, 14 and the deflective light beam a4 after second reflection at the deflective reflecting facet 11 passes through the space 15.
