    摘要： A powder detection device includes a detection mechanism including an oscillation unit and a vibrated member, a vibrating member, and a detection unit. The oscillation unit outputs a signal having a frequency according to a state of a magnetic flux passing a space facing the oscillation unit. The vibrated member affecting the magnetic flux and disposed inside a container to face the oscillation unit via the container is vibrated by the vibrating member in a direction of facing the oscillation unit. The detection unit acquires frequency information of the signal at predetermined periods, determines presence/absence of an error of the detection mechanism based on error information associating a type of the error with a state of the signal, detects vibration of the vibrated member based on a change in the frequency information, and detects a remaining amount of powder in the container based on the detected vibration.

    摘要： A fluid detection apparatus to detect quantity of a fluid having flowability and stored in a casing includes an oscillator disposed outside the casing to output a frequency of an oscillation signal corresponding to a magnetic flux passing through a space near the oscillator, a vibrator made of material effecting the magnetic flux and disposed inside the casing, a vibration trigger disposed inside the casing to vibrate the vibrator, and circuitry to acquire frequency-related information related to the frequency of the oscillation signal output from the oscillator, detect the vibration of the vibrator based on a change of the frequency-related information, determine whether the vibration of the vibrator converges during a convergence-checking time period defined after the vibrator is vibrated by the vibration trigger, and detect the quantity of the fluid in the casing based on a convergence determination result of the vibration of the vibrator.

    摘要： A powder detector to detect an amount of powder in the powder container includes a wall without a through hole, a vibration plate attached to an inner face of the wall, a contact member to vibrate the vibration plate, and a vibration detector to detect a vibration state of the vibration plate. The vibration detector is attached to an outer face of the wall to face the vibration plate via the wall. The powder has flowability, and the vibration state of the vibration plate is affected by the powder in the powder container.
