摘要： An apparatus for obtaining a retinal image of an eye has a control logic processor (214) for executing a sequence of operations for obtaining the image. A visual target (162) orients the eye of a patient when viewed. An indicator element (410) provides a signal that indicates that the patient is in position. A cornea focus detection section (450) indicates cornea focus, in cooperation with the control logic processor (214). An alignment actuator aligns the optical path according to a signal obtained from the cornea focus detection section (450). A retina focus detection section (452) detects retina focus in cooperation with the control logic processor (214). A focusing actuator (406) is controlled by instructions from the control logic processor (214) according to a signal obtained from the retina focus detection section (452). An image capture light source is energized by the control logic processor (214) for illuminating the retina.

摘要： A fundus camera (10) obtains a retinal image using a light source (62), a ring aperture (58) conjugate to the cornea, and a first aperture (54) conjugate to the iris. An apertured mirror (52) redirects the ring illumination toward the eye. An objective lens (50) between the apertured mirror (52) and the eye has an entrance pupil between the iris and the cornea of the eye. The objective lens (50) directs the ring illumination into the pupil of the eye and directs a reflected image-bearing light from the retina through the apertured mirror (52). A second aperture (64), conjugate to a plane between the cornea and the iris of the eye, forms an aperture stop for the reflected image-bearing light. A third aperture (68) is conjugate to the cornea for blocking light reflected. A sensor (70) provides an image of the retina.

摘要： An apparatus for recording an image onto a sheet medium has an entrance drive roller paired with a corresponding entrance pressure roller to form an entrance nip for transporting the sheet medium into an image recording section. The image recording section has a write head for recording onto a portion of the sheet medium being transported between the entrance nip and exit nip. The exit nip is formed by a drive roller paired with a corresponding exit pressure roller for transporting the sheet medium out from the image recording section. A motor provides rotary motion to a pinion roller mechanically coupled to the entrance and exit drive rollers. A loading mechanism provides a loading force to nest the pinion roller into rotational contact against a portion of the entrance and exit drive rollers.

摘要： A printing apparatus (10) exposes an image onto a photosensitive medium (14), having a printhead (20) with a linear array of exposure sources (40), each exposure source (12) operable at a variable intensity. A shuttle mechanism (16) moves the printhead (20) over the photosensitive medium (14) in a reciprocating motion between one end of a carriage assembly (72) and the other. An encoder (38) is coupled to the shuttle mechanism (16) for providing an index encoder pulse (60) at each of a plurality of increments of position of the shuttle mechanism (16) along the carriage assembly (72). Exposure control logic calculates a shuttle velocity according to index signal timing and adjusts the variable intensity of each exposure source (12) according to the shuttle velocity.
