摘要： A light beam (L) modulated with image information has its optical axis moved in a given direction by a light beam moving unit (38), and reflected successively by a plurality of rotating reflecting mirrors (58, 60) of a spinner (40) to a photosensitive medium (S). The movement of the light beam (L) which is caused by the light beam moving unit (38) is controlled depending on the speed at which the reflecting mirrors (58, 60) move and the direction in which the reflecting mirrors (58, 60) move, so that the light beam (L) reflected by each of the reflecting mirrors (58, 60) can scan the photosensitive medium (S). An image represented by the image information can efficiently be recorded on the photosensitive medium (S).

摘要： Parallel laser beams #1, #2 and #3 produced by splitting one laser beam into three, are introduced to an optical scanning device (2) along the central axis of a recording cylinder (24), the optical scanning device being disposed on the central axis of the recording cylinder and rotated thereabout, having an inclined mirror surface (4), the recording cylinder holding a recording sheet (S) on an interior surface thereof. The laser beam #2 incident upon the mirror surface at its center of rotation is reflected at the point of incidence, while the laser beams #1 and #3 are deflected by acousto-optical devices (10X, 14X) back and forth in the opposite directions in synchronism with the rotation of the optical scanning device, in parallel planes held at a distance and including the laser beams #1 and #3 therein, thereby to give the laser beams #1 and #3 angles of incidence upon the mirror surface necessary in order for the laser beams #1, #2 and #3 after reflected to produce scanned loci running parallel to each other at a given interval on the recording sheet, regardless of rotational positions of the optical scanning device. To adjust a relative difference in the lengths of the scanned loci, timing at which the laser beams #1, #2 and #3 are turned on/off is controlled. When the laser beams #1 and #3 are deflected so as to gyrate along a conical plane whose central axis is that of the recording cylinder, the laser beams #1, #2 and #3 produce scanned loci always running parallel to each other at a given interval with the same scanning lengths on the recording sheet.

摘要： PROBLEM TO BE SOLVED: To provide an inner drum exposing device capable of performing recording in a way that halftones can be stably expressed by using an FM screen.
SOLUTION: A light beam L of linearly polarized light emitted from a light source 30 is converted to circularly polarized light by a quarter-wave plate 32 arranged in an optical path. The light beam L converted to the circularly polarized light is separated to an ordinary ray and an extraordinary ray in a vertical scanning direction at equal density when the light beam transmits an optical element 26 of a uniaxial crystal and is thereafter reflected by a reflection mirror surface 18A of a scanning means 16 and is made into a distribution of an approximately rectangular shape with respect to the vertical scanning direction to a condensing point on a recording medium 14. In addition, the light beam is condensed to a beam spot of a steepened edge and is subjected to exposure processing. As a result, the image unevenness to the vertical scanning direction is appropriately suppressed without being affected by the fluctuation in color development threshold of the recording medium 14 and the intensity fluctuation etc., of the light beam L and the expression of the halftones can be stably recorded by using the FM screen.

摘要： An optical scanning apparatus capable of suppressing a track error is provided. The apparatus includes a swing mirror supported by a torsional vibration system having a first natural frequency and a second natural frequency that is a double of the first natural frequency, and a driving unit applying a swing torque to the vibration system. The apparatus can detect passage of an optical beam at two locations and output track information of the swing mirror, and perform feedback control. When the feedback control is performed, the apparatus sequentially switches target tracks of scanning in a forward and a backward direction, the phases of the second natural frequency of the target tracks being mutually reversed, calculates an amount of offset compensation based on a difference between the predetermined target track and the track for each scanning in the forward and backward direction, and reflects the amount in the feedback control.

摘要： Optical scanners are configured so a principal ray of an incident beam from a light source device to a deflector and a principal ray of a scanning beam from the deflector to a scanned surface travel on the same side (or opposite sides) of an optical axis of an optical element(s) respectively wherein entrance and exit surfaces of the optical element(s) are both convex (or both concave) toward the deflector in the sub-scanning section. In various embodiments, the aforementioned principal rays travel on the same side, and surfaces are convex toward the deflector in the sub-scanning section. In various embodiments, the aforementioned principal rays travel on opposite sides, and surfaces are concave toward the deflector in the sub-scanning section. Embodiments may beneficially separate the scanning beam from ghost light and/or be incorporated in image forming apparatuses.
