摘要:
A mask that determines an imaging range of an ocular fundus is disposed in the optical system at the position conjugate to the fundus. The size of the mask on the ocular fundus is calculated in accordance with the optical imaging parameters of the optical system and the diopter of a subject eye and the eye axial length thereof. Two points are specified on the image on the display screen. The actual distance between the specified points on the ocular fundus is calculated based on the calculated mask size on the ocular fundus, a coordinate distance of the mask on the display screen and a coordinate distance between the two specified points on the display screen. With such a constitution, the actual distance on the ocular fundus is derived from the optical imaging parameters in the optical system and the subject eye parameters, which affect the imaging magnification. This assures the precise measurement of the actual distance on the ocular fundus from the image on the display screen.

An image forming device includes: a toner image forming unit that forms a toner image onto a recording medium; a controlling unit that controls the toner image forming unit such that a test image is formed on the recording medium; a sheet transfer unit that transfers the recording medium having the toner image formed thereon by the toner image forming unit; a fixing unit that fixes the toner image formed by the toner image forming unit onto the recording medium; an image detecting unit, disposed downstream from the image fixing unit along the sheet transfer unit, that detects the test image formed on the recording medium; and a calibration unit that performs a color calibration process based upon the test image detected by the image detecting unit.

A light scanning device deflects a plurality of light beams by a deflecting means performs divided scanning on a single scanning line on a photoconductor with the plurality of deflected light beams. When the scanning line is scanned, a detecting means detects a light beam passing through a predetermined position in front of a position where the light beam first strikes an image forming range on the photoconductor. An oscillating means oscillates a specified number of clocks in a time interval from when the light beam is detected by the detecting means until it is detected thereby again. An adjusting means makes adjustments so as to irradiate a plurality of light beams based on clocks oscillated by the oscillating means. In a time interval after the light beam is detected by the detecting means until it is detected thereby again, a plurality of light beams are irradiated based on the specified number of clocks. Therefore, even if unevenness occurs in the deflecting speed of the deflecting means, dots can be formed at the same intervals in scanning a plurality of scanning lines. Thus, it is possible to prevent discontinuous joints occurring in each of the images formed with a plurality of light beams.

Light scanning devices forming electrostatic latent images on photosensitive bodies are disposed so as to correspond respectively to the plurality of photosensitive bodies which correspond to a plurality of colors, respectively. Electrooptical elements are disposed on light paths of light beams. The electrostatic latent images formed on the respective photosensitive bodies 1 are respectively developed by developing means. Developed electrostatic latent images are respectively superposed together and transferred onto a sheet, so that a color image is formed. Images-for-detecting-offset-amounts, which are formed on a conveying body by the light scanning devices, are detected, and offset amounts of images of the respective colors are detected. Based on detected offset amounts, voltages are applied to the respective electrooptical elements such that the offset amounts become values of a predetermined range.

A reversing transmission for marine propulsion units or the like. The reversing transmission includes a multiple disc clutch assembly that is cooperative with a pair of bevel gear and clutch assemblies. These bevel gear and clutch assemblies are made up of a two-part construction each comprised of a bevel gear and a tubular sleeve that is affixed to the bevel gear and which carries a series of clutch plates. A clutch actuating piston is also incorporated that has a tapered end face so as to improve and make smoother the clutch engagement.
