摘要： In a digital copying machine using a multi-beam optical system, a light beam position detector situated on a line extended from the surface of a photosensitive drum detects the passing position of each light beam scanned by a polygon mirror rotated by a polygon motor. A CPU calculates control amounts for galvanomirrors by using a beam position detector output processor, on the basis of the detection result of the beam position detector. Based on the calculated control amounts, galvanomirror drive circuits drive the galvanomirrors, thereby to control the positions of the beams in a sub-scan direction. The passing positions of the beams can be precisely detected with no special precision in assembling the optical system. In addition, the positions of the beams in the sub-scan direction can be controlled at predetermined positions, even if some change occurs in the structure of the optical system due to a variation in ambience or a variation with the passing of time.

摘要： In an apparatus for adjusting the intensity of a light beam, a first driving current which is stepwisely increased in a first cycle is supplied to a semiconductor laser. The light beam is deflected to scan a photosensitive drum and is detected to generate a positional signal by a photodetector outside of the drum. The intensity of the light beam is also detected by a monitor detector and compared with a predetermined target intensity. The comparison result is latched in a latch circuit to determine a first drive signal. When the intensity of the light beam reaches the target intensity after the generation of the positional signal, a second drive signal is generated in a second cycle longer than the first cycle instead of the first drive signal and is supplied to the semiconductor laser. The second drive signal is determined in accordance with the comparison result latched in the latch circuit.

摘要： An image density detecting device for an image forming apparatus includes a light diffusing member made of a transparent resin. The light diffusing member has a substantially rectangular sectional profile, with the longitudinal dimension thereof greater than the width of the document, and it is disposed below the document such that it extends in the width direction thereof. The side of the light diffusing member opposite its light receiving surface constitutes a diffusing reflecting surface which is formed by forming blade-like notches on this side. A photodiode is embedded in the end face of the light diffusing member on the side thereof opposite the ends of the blade-like notches.Light reflected by a portion of the document between the opposite edges thereof is received on the light receiving surface of the light diffusing member and is focusedly reflected by the diffusing reflecting surface toward the end face on the side of the photodiode to be detected thereby.
