  • Publication number: 20190286012
    Abstract: A toner cartridge includes a casing, an auger rotatable about an axis extending in a first direction, an auger gear rotatable with the auger, an agitator aligned with the auger in a second direction, an agitator gear rotatable with the agitator, and a detection gear positioned opposite to the auger gear with respect to the agitator gear in the second direction. The detection gear is rotatable from a first position to a second position. At the first position, a through-hole or a cutout of the detection gear is positioned farther away from the auger than an outer surface of another end portion of the casing in the second direction is. At the second position, a portion of the detection gear different from the through-hole or the cutout is positioned farther away from the auger than the outer surface of the another end portion of the casing is.

  • Patent number: 9056490
    Abstract: In an optical scanning device, a first deflector rotates about a first axis in a first direction and deflects light to scan the deflected light, and a second deflector rotates about a second axis parallel to the first axis in a second direction opposite to the first direction and deflects light to scan the deflected light. The light detecting unit detects the light deflected by the first deflector and the light deflected by the second deflector. As viewed in an axial direction along the first and second axes, the light detecting unit is disposed on one side relative to a first line and between second and third lines, the first line passing through the first and second axes, the second line passing through the first axis and being perpendicular to the first line, and the third line passing through the second axis and being perpendicular to the first line.
