    摘要: An image reading apparatus includes a conveyance unit, a first reading unit, a first guide portion, a second reading unit, and a second guide portion. The second reading unit includes a rectangular transparent member, an optical reading unit, a housing, a first and a second contact portions, a first and a second pressing members, and a protruding portion. The first and the second contact portions are protruding from a facing surface of the housing. The protruding portion, when viewed from an upstream side in a conveyance direction of a recording material passing through a conveyance path between the second reading unit and the second guide portion, is disposed between the first contact portion and the second contact portion and protruding from the facing surface of the housing, a protruding amount of the protruding portion being smaller than protruding amounts of the first and the second contact portions.

    摘要: The image-forming apparatus includes multiple developing units that form images using multiple color developers, an image carrier that, in color displacement detection, carries the developers transferred thereon at mutually different image-carrying positions, an optical sensor that projects a light to the image carrier and receives a reflected light from the image carrier, and an acquirer that acquires, in response to output from the optical sensor, passage times at which the developers on the image carrier respectively pass a detection position. The optical sensor receives a diffusively reflected light from a non-transferred area of the image carrier on which the developers are not transferred. The acquirer acquires the passage times of all the developers, in response to changes in the output from the optical sensor at an output level higher than that corresponding to a diffusively reflected light from the developers on the image carrier.

    摘要: A recording apparatus includes a transport section that transports a recording medium; and a floating detection section that detects floating of the recording medium. The floating detection section has a plurality of light emitting elements capable of emitting light to positions different from each other in the recording medium and one light receiving element capable of sequentially receiving reflected light emitted from the plurality of light emitting elements. The floating in the different positions is capable of being detected from received light intensity of the reflected light.

    摘要: An effective image area can be properly corrected in accordance with the quantity of light from an irradiation unit by selecting, as the effective image area, pixels having light quantities more than or equal to a threshold value that allows accurate acquisition of a surface image of a recording medium, on the basis of a light quantity distribution of the light from the irradiation unit. This reduces the influence of mounting accuracy of the irradiation unit, and allows the recording medium to be identified accurately.
