  • Patent number: 10496009
    Abstract: A toner container includes a container body, an opening, a cover, a toner discharge port, a shutter, a cylindrical structure, protrusions, and an identifier. The shutter is attached to the cover and includes a main shutter covering the toner discharge port. The main shutter moves between a closed position to close the toner discharge port and an open position to open the toner discharge port. The protrusions are on both sides of the cover and protrude in a direction orthogonal to a toner container mounting direction. The identifier is on the cover to indicate a toner color. The cylindrical structure's leading end is downstream of leading ends of the protrusions in the mounting direction. The main shutter's leading end is downstream of the protrusions' leading ends in the mounting direction when the main shutter is in the closed position. The protrusions are downstream of the identifier in the mounting direction.

  • Patent number: 10442663
    Abstract: In a cage lighting device for an elevator, a lighting cover includes a main cover, a first auxiliary cover opposing a first cage wall, and a second auxiliary cover opposing a second cage wall. Respective dimensions of the first and second auxiliary covers in a lengthwise direction of the lighting cover are smaller than a dimension of the main cover in the lengthwise direction of the lighting cover. By loosening a first auxiliary cover fastening tool, the first auxiliary cover becomes capable of sliding in the lengthwise direction relative to a lighting cover attachment member between a position adjacent to the main cover and a position contacting the first cage wall.
