IPC: F16H48/12
Filed: 1993-01-12
Abstract: PURPOSE:To cope with the high speed rotation by installing a differential device which differentially operates for a main spindle which is rotationally driven, applying rotation to the differential device from an input shaft, taking out the rotation in a decelerated state from an output shaft and adjusting the rotation phase between the main spindle and the input shaft. CONSTITUTION:When a main spindle 2 is rotationally driven through a belt 10, the rotation is transmitted to a pulley 21 through a belt 26, and a rotary sleeve 17 is revolved. Then, the circular spline of a harmonic reduction gear 19 is rotated, and a flex spindle is acceleratedly rotated, and a rotational difference is generated between the fixed sleeve 17 and a drive shaft 18. The revolution of the drive shaft 18 is transmitted to a pulley 15 through a belt 27, and an input shaft 4 is fevolved, and an output shaft 15 is rotated at the equal speed. If an adjusting motor 20 is revolved. the larger rotation phase difference is generated between both 17 and 18, and the rotation phase difference between a revolution sleeve 2b and an input shaft 4 is generated, and an output shaft 5 is deceleratedly rotated through a harmonic reduction gear 3.

Filed: 1986-01-10
Abstract: PURPOSE:To obtain a compact device and to shorten an image formation time by transferring plural toner images which are formed on an image formation drum one over another onto recording paper at a time and forming a reference toner image successively on one straight line perpendicular to the moving direction of the image formation drum. CONSTITUTION:The image formation drum 40 which is already charged electrostatically and uniformly is exposed to the 1st reference toner image, e.g. cyan color reference toner image by a laser beam. Thus, a latent image of the 1st reference toner image (cyan color reference toner image) 71 is formed by said exposure and then the 1st exposure (corresponding to cyan) of an image part is carried out successively. Similarly, latent images of, for example, a red reference toner image 71b and a black toner image 71c are formed and the drum is exposed to them. A sensor 72 when finishing measuring the density of the 3rd reference toner image (black) 71c returns to a position facing to the 1st reference toner image 71a with the signal of a control circuit and gets ready to measure the density of a next image. Consequently, a multicolor toner image with excellent color toner is obtained by density measurement and control from toner images formed on the image formation drum 40 one over another.

Title: Beam scanner
Inventor: TAKANO YOSHINOBU
IPC: G02B26/12
Filed: 1990-01-11
Abstract: PURPOSE:To eliminate an influence upon the change of a reflection position of a polygon mirror by inclining a scanning surface at higher scanning speed in a direction so as to be close to a holographic ftheta lens. CONSTITUTION:Since the scanning speed is made low at a part where the power of a holographic ftheta lens 6 is strong, a scanning surface 7 is inclined so that the scanning speed can be increased when an incident position is moved to the part with the strong power according to the fluctuation of the reflection position on a polygon mirror 4. In other words, the asymmetricity of the scanning speed can be corrected by inclining the scanning surface 7 at the higher scanning speed to the holographic ftheta lens 6 in the direction so as to be close to the holographic ftheta lens 6. Thus, for the holographic ftheta lens 6, the shape can be miniaturized and a spatial frequency can be lowered. Further, even when a scanning angle is enlarged, aberration can be decreased.

Title: Auto-focusing device
Inventor: AKASHI AKIRA
IPC: G02B7/28
Filed: 1987-01-12
Abstract: PURPOSE:To hold the original focused state of an object even if a range finding field is shifted by hand vibration or the like by inhibiting the driving of a lens for a prescribed time when a defocused value after focusing is high. CONSTITUTION:A computer PRS decides the size of defocused value after focusing, and when the defocused value is low, immediately drives the lens LNS in accordance with the defocused value and keeps the hollow-up property of the lens to the object. When the defocused value is high, the computer PRS regards the state of the lens as a shifted state from a range finding field and inhibits the object driving based upon the detected defocused value until a prescribed time elapses from the focused time. Even if the range finding field is shifted from the original object by hand vibration or the like, the focused state of the original object can be maintained.
