摘要： In a digital copying machine using a multi-beam optical system, a sensor pattern SH for sensing the power of each of the light beams a to d scanning the surface of a photosensitive drum and sensor patterns SB1 to SF1, SB2 to SF2 for sensing the passing positions of the beams are provided in a light beam position sensing unit. The sensor patterns SB1 to SF1, SB2 to SF2 are arranged linearly in the sub-scanning direction at intervals corresponding to two resolutions. The power of each light beam on the surface to be scanned is controlled so as to be in a specific range. Even when the light beams are scanned with different resolutions, they can be controlled with high accuracy so as to constantly have an ideal positional relationship between them. This always assures high picture quality.

摘要： A light beam scanner unit includes a light beam generating unit for generating light beams at a fixed power, a polygon mirror for reflecting light beams generated from the light beam generating means toward a surface to be scanned, thereby scanning it, and a light beam power sensing unit for sensing light beam power for scanning a surface to be scanned with the polygon mirror. This light beam scanner unit further has a mirror contamination sensing unit for sensing contamination of the polygon mirror by comparing a sensing result obtained from the light beam power sensing unit when light beams are emitted by the light beam generating unit with a preset reference value.

摘要： In a digital copying mechine using a multi-beam optical system, first light receiving elements of a light beam detector placed on the extension of the surface of a photosensitive drum detects the positions of paths of scanning light beams in the sub-scanning direction. On the basis of the results of this detection, the amount of control for the position of the path of each light beam is calculated. Galvano mirrors, adapted to reflect the light beams onto the surface of the photosensitive drum, are driven accordingly, so that the paths of the light beams are properly positioned in the sub-scanning direction. Second light receiving elements of the light beam detector detect times at which the light beams move across the light beam detector. A sync clock is produced after a delay from when each light beam moves across the light beam detector. The spacing between each second light receiving element is set to an integral multiple of the length of one dot formed by a light beam on the photosensitive drum in the main scanning direction. In synchronism with the sync clocks, pixel clocks and image data are applied to laser oscillators to form an image on the surface of the photosensitive drum. A light beam scanning apparatus is provided which can properly control the positions of lines scanned by the light beams on the photosensitive drum surface and hence can maintain high image quality at all times.

摘要： All electric charges accumulated in a line sensor are transferred via a first shift gate to a first analog shift register. By controlling the width of a shift pulse signal to be supplied to a second shift gate, the amount of an electric charge transfer when the electric charges on the first analog shift register are transferred to a second shift register is controlled. As a result, the amount of the electric charges on the first analog shift register is controlled to a desired value. Accordingly, the amplitude of an image signal outputted from the first analog shift register can be easily adjusted. Further, the sensitivity of a CCD line sensor and variation of light amount of a light source can be corrected.

摘要： A light beam position detecting device detects the passage positions of a plurality of light beams for scanning the surface of a photosensitive drum. The light beam position detecting device has a sensor pattern for generating an output which is continuously changed in a wide range with a variation in the passage position of the light beam in a sub-scanning direction perpendicular to a main scanning direction of the light beam. The sensor pattern precisely detects the relative scanning position of the light beam in a wide range. The passage positions of the plurality of light beams for scanning the surface of the photosensitive drum are controlled to a preset position based on the output of the sensor pattern.

摘要： A four-line CCD sensor is structured by line sensors R, G, B in which color filters are respectively disposed on surfaces of light receiving elements, and a line sensor BK at which no color filter is disposed. Amplitudes of signals which are outputted from the line sensors R, G, B at a time of reading a color document, and an amplitude of a signal which is outputted from the line sensor BK at a time of reading a monochrome document are adjusted so as to be substantially equal to one another. In a case in which a color document is read, outputs of the line sensors R, G, B are selectively provided, and in a case in which a monochrome document is read, output of the line sensor BK is selectively provided.
