  • Patent number: 11126111
    Abstract: A toner amount detector detects an amount of toner in a toner bottle. The toner amount detector includes at least one pair of electrodes disposed opposite each other via the toner bottle, grounding members disposed outboard of the at least one pair of electrodes and electrically grounded, circuitry to switch a first detection processing and a second detection processing, and an indicator to indicate that a positional deviation of the at least one pair of electrodes has occurred. The grounding members face the at least one pair of electrodes. The first detection processing detects the amount of toner based on a first capacitance between the at least one pair of electrodes, and the second detection processing detects a positional deviation based on a second capacitance between each of the grounding members and a corresponding one of the at least one pair of electrodes.

  • Patent number: 10584798
    Abstract: In a seat component received in a receiving region of a first body of a body, one surface of a contacting portion and one surface of an engaging portion are planar and are flush with each other, and the other surface of the contacting portion and the other surface of the engaging portion are planar and are flush with each other. The engaging portion engages two portions of the first body, which form one opening of the receiving region, in a state where a distal end of the seat component reaches another opening of the receiving region. Furthermore, in the state where the engaging portion engages the portions of the first body, a second body of the body covers the one opening and contacts the engaging portion. Thereby, the engaging portion engages the three portions of the body, so that movement of the seat component is effectively limited.

  • Patent number: 10536306
    Abstract: Switch units control ON and OFF of communication between a master device and slave devices. Signal levels of communication lines between switch units and slave devices are maintained at a predetermined level. A switch unit in a first stage is turned on and off by a first switch control signal. A switch unit in a second stage is turned on and off by a switch control signal generated based on a level of a communication line in the first stage and the first switch control signal. A switch unit in each of subsequent stages is turned on and off by a switch control signal generated based on a level of a communication line in a preceding stage and a switch control signal in a second preceding stage. A portion of ground short circuit is identified based on states of communication between the master device and the slave devices.
