    摘要： An inner focus type telescope includes a sighting objective lens, a focusing lens, a horizon compensating optical system, a focal plane, and an eyepiece through which an object image formed on the focal plane can be viewed, arranged in this order from the object side. The position of the focusing lens is adjustable to form the object image on the focal plane in accordance with the distance of an object to be viewed. The telescope further includes a beam splitting optical system provided in the optical path between the objective lens and the focal plane to split the optical path, a surface equivalent to the focal plane, provided in the beam splitting optical system, and a focus detecting system which detects the state of the focus at the equivalent surface.

    摘要： An image forming apparatus includes a liquid discharge device and processing circuitry. The liquid discharge device includes at least one nozzle group, where N represents an integer, to discharge liquid. The processing circuitry causes the first nozzle group to discharge in a first scan, causes the second nozzle group to discharge in a second scan, and causes the N-th nozzle group to discharge in an N-th scan to form a complete image. The processing circuitry, with respect to an image completion rate indicating a rate of an image formed by each of the first nozzle group to the N-th nozzle group in the complete image, sets the image completion rate of a portion of the first nozzle group adjacent to the second nozzle group in the sub-scanning direction to be not higher than the image completion rate of any one of the second nozzle group to the N-th nozzle group.

    摘要： A liquid discharge apparatus includes a liquid discharge head having at least one nozzle array including a plurality of nozzles lined in a nozzle array direction; a two-dimensional image sensor to capture an image formed by the liquid discharge head; and circuitry. The circuitry is configured to divide the nozzles into a plurality of nozzle units; form a pattern including a plurality of unit patterns with liquid discharged from the nozzle units, respectively; and detect a defective nozzle based on a captured image of each of the unit patterns. The unit patterns are arranged in a staggered manner. Each unit pattern is smaller in size than an image capture range of the two-dimensional image sensor. Each unit pattern includes a number of columns of lines extending in a direction perpendicular to the nozzle array direction, and the number of columns is not smaller than twice the number of nozzle arrays.

    摘要： An image forming apparatus includes a carriage that includes a head including a black nozzle array in which a plurality of nozzles are arranged and a color nozzle array in which a plurality of nozzles are arrange, the black nozzle array being disposed at a position shifted in the sub-scanning direction downstream in a medium conveying direction with respect to the color nozzle array; a conveying unit configured to convey a recording medium in a sub-scanning direction; and a control unit. The control unit forms an image by the color nozzle array in a main scanning in one direction, relatively moves the recording medium to a subsequent main-scanning position thereafter, and forms an image by the black nozzle array on the image formed by the color nozzle array in a following main scanning in the other direction so as to complete an image for one scanning area.
