摘要： The invention provides an optical write line head comprising multiple rows of light emitter devices lined up corresponding to the respective positive lenses located in array form, wherein even with a fluctuation of its write plane in an optical axis direction, there is none of variations resulting from displacements of light emitting dots. A plurality of light emitter blocks 4, each including at least one row of light emitter devices lined up in a main scan direction, are located at a spacing in the main scan direction to define a light emitter array 1. On the exit side of the light emitter array 1, a lens array 6 comprising one positive lens system 5 in alignment with each light emitter block 4 is located parallel with the light emitter array 1, and a write plane 41 is located parallel on the imaging side of the lens array 6. A stop plate 30 forming an aperture stop 31 is located near a light-gathering position at which parallel light incident from the write plane side on each positive lens system comes together.

摘要： An image forming method which generates a video signal corresponding to an image forming command based on a video clock signal, modulates a light beam according to the video signal, and scans the modulated light beam along a main scanning direction by means of an oscillation mirror which resonates based on a drive signal, so as to form a latent image in an effective image region of a latent image carrier, the method includes: synchronizing the drive signal with the video clock signal to synchronize a detection signal with the vide clock signal, the detection signal being output from a detector which detect the light beam scanned in the main scanning direction in a region away from an effective scan region which corresponds to the effective image region; controlling a resonant frequency of the oscillation mirror based on the detection signal so that the resonant frequency of the oscillation mirror almost coincides with the frequency of the drive signal; and adjusting a position, at which the latent image is written over the latent image carrier, is adjusted by adjusting output timing of the video signal based on the detection signal from the detector.

摘要： A light scanning apparatus makes a light beam scan along a main scanning direction on an effective scanning region which has a predetermined width. The apparatus comprises: a light source which emits the light beam; a deflector which includes an oscillation mirror which oscillates about an oscillatory axis which is orthogonal or approximately orthogonal to the main scanning direction, deflects the light beam emitted from the light source using the oscillation mirror, and makes the light beam scan a second scanning range which contains but extends beyond a first scanning range which corresponds to the effective scanning region; a detector which detects the scanning light beam which moves through a position which is outside the first scanning range but is within the second scanning range, and outputs a signal; and a controller which controls a mirror drive signal fed to the oscillation mirror based on the output signal from the detector and accordingly adjusts the amplitude of the oscillation mirror. In the apparatus above, the controller stops driving the oscillation mirror when confirming based on the output signal that the oscillation mirror is under abnormal control.

摘要： A transmission optical system comprises a concave surface mirror whose reflection surface is directed toward a deflection mirror surface and a transmission lens which is disposed between the concave surface mirror and the deflection mirror surface. A light beam deflected by a deflecting element at a first deflection angle is guided to the concave surface mirror via the transmission lens, and the light beam returned by the concave surface mirror is guided to the deflecting element via the transmission lens. In consequence, the deflecting element reflects the light beam twice, and the light beam is emitted toward a scanning lens at a second deflection angle which is larger than the first deflection angle.

摘要： A light beam L from a laser source 62 impinges upon a deflection mirror surface 651 from the direction of a pivot axis (sub scanning direction Y) at an acute angle γ with respect to the surface normal NL to the deflection mirror surface 651, and the light beam scans in a main scanning direction X. Since the light beam is incident upon the deflection mirror surface 651 along the direction of the pivot axis, the length of a movable plate 653 in the main scanning direction X may be relatively short. Further, a first optical system 63 shapes the light beam incident upon the deflection mirror surface 651 into an elongated cross sectional shape which is long in the main scanning direction X, and the movable member 653 is finished as an elongated strip which elongates in the main scanning direction X. Hence, the movable plate 653 is light-weight and can pivot stably at a faster speed than in a conventional apparatus.
摘要翻译：来自激光源62的光束L相对于偏转镜表面651的相对于表面法线NL以锐角γ从枢轴（副扫描方向Y）的方向入射到偏转镜面651，光束沿主扫描方向X扫描。由于光束沿着枢转轴线的方向入射到偏转镜面651上，所以可动板653在主扫描方向X上的长度可能相对较短。此外，第一光学系统63将入射在偏转镜面651上的光束成形为在主扫描方向X上长的细长横截面形状，并且可移动部件653被完成为在主体中伸长的细长条因此，可移动板653重量轻并且能够以比传统装置更快的速度稳定地枢转。

摘要： A mirror driver drives deflection mirror surfaces into a pivoting action at a frequency belonging to a first drive frequency band in which the high-frequency side of a first resonance frequency band partially overlaps the low-frequency side of a second resonance frequency band, so that the deflection mirror surfaces deflect a light beam. Hence, the deflection angles of light beams change, while canceling out each other the changes of the deflection angles of the light beams deflected by the deflection mirror surfaces owing to changes of resonance characteristics. Because of this, even when the resonance characteristics change, it is possible to stabilize the deflection angle of the light beam deflected by the first deflection mirror surface and further deflected by the second deflection mirror surface.
摘要翻译：反射镜驱动器将偏转镜面驱动成属于第一驱动频带的频率的转动动作，其中第一共振频带的高频侧部分地与第二共振频带的低频侧重叠，使得偏转镜面偏转光束。因此，由于共振特性的变化，光束的偏转角变化，同时抵消由偏转镜面偏转的光束的偏转角的变化。因此，即使在谐振特性变化的情况下，也可以使由第一偏转镜面偏转的光束的偏转角稳定，并进一步被第二偏转镜面偏转。

摘要： In a color image forming apparatus, a looped belt member is stretched and circulated by at least a drive roller and a driven roller so as to have a tensed side and a slack side. Each of plural image supporting members supports a single color toner image thereon, and abuts onto the slack side of the belt member to define a transferring position at which the toner image is transferred onto either the belt member or a recording medium held by the belt member, while being rotated. A circumferential velocity of each image supporting member is determined so as to be higher than a circulation velocity of the belt member.
