  • Patent number: 11011398
    Abstract: In equipment that supplies a processing liquid on a top surface of a substrate while holding the substrate horizontally in a chamber a generation status of fumes is determined. Specifically, an image of a predetermined imaging area in the chamber is captured. Then, the generation status of fumes in the chamber is determined based on luminance values of the captured image acquired by the capturing of an image. Accordingly, it is possible to quantitatively determine whether a generation status of fumes in a chamber is normal.

  • Patent number: 10317820
    Abstract: A toner supply device includes a toner container, a detector, and a determiner. The toner container is configured to contain toner to be supplied to a developing device. The toner container is capable of discharging a prescribed amount of toner contained therein. The detector is configured to detect an amount of toner to be supplied to the developing device. The determiner is configured to estimate a timing at which toner remaining in the toner container is completely consumed, based on a driving amount applied for discharging toner from the toner container during a time period from when the prescribed amount of toner is discharged from the toner container until when the detector detects an amount of toner equal to the prescribed amount of toner.

  • Patent number: 9316988
    Abstract: The rotary power transmission mechanism includes a flange member fitted to one end of a cylindrical member, a shaft inserted through an axial center of the flange member, and a pin member inserted through the shaft in a radial direction of the shaft. The flange member has a first contact portion and a second contact portion that have point symmetry with respect to an axial center of the shaft. When the pin member is rotated in one direction by the shaft rotating in the one direction, the first contact portion contacts a first end portion of the pin member and the second contact portion contacts a second end portion of the pin member. The pin member, when rotating in the one direction, pushes against the first contact portion and the second contact portion, rotates the flange member in the one direction, and thereby transmits rotary power to the cylindrical member.

  • Patent number: 9280095
    Abstract: A developing device forms an image by developing an electrostatic latent image on a photoreceptor rotating about a rotation axis. The developing device includes a housing having an opening opposite the photoreceptor, a developing sleeve disposed inside the housing, a magnetic body disposed in a central portion of the developing sleeve and not in no-magnet portions thereof at both sides of the central portion, and seal members supported by the housing. Each of the seal members shields either one of portions of the photoreceptor that are located opposite the no-magnet portions and is in surface contact with either one of end portions of the photoreceptor farther from a center of the photoreceptor than the no-magnet portions. Each of the seal members includes, at an end thereof closer to the center of the photoreceptor than the other end thereof, a non-contact portion that is not in contact with the photoreceptor.

  • Patent number: 9176472
    Abstract: An exhaust fan, an exhaust duct through which a discharged gas flows and a filter which is provided in the exhaust duct are included. A curved portion is provided in the exhaust duct, and the filter is provided on a downstream side in a direction of flow of the gas with respect to the curved portion. On an inside wall of the curved portion of the exhaust duct on an outer side in a radial direction, a first flow control member that uniformizes the amount of the gas flowing through the filter is provided so as to be perpendicular to the shaft of the curved portion, and a space is formed between the first flow control member and an inside wall of the curved portion on an inner side in the radial direction.

  • Patent number: 9164421
    Abstract: A first shutter covers a first supply port formed in an outer peripheral surface of a main body, and can move in an outer peripheral direction along the outer peripheral surface of the main body. A pair of guiding members respectively formed on both ends of the first shutter guide the first shutter in the outer peripheral direction. A lock mechanism fixes the first shutter to achieve a closed state of the first supply port. The lock mechanism includes a protrusion provided to the first shutter, the protrusion being capable of engaging with a recess formed in the outer peripheral surface. Fixing by the lock mechanism is released when the protrusion elastically deforms and is disengaged from the recess. The protrusion, the recess, and the first supply port are disposed along a virtual curve between the pair of guiding members.

  • Patent number: 8862032
    Abstract: In a transport pipe having a first opening portion through which toner is fed in from a toner hopper and a second opening portion through which the toner is discharged to a development device, a transport screw in which a helical blade is formed on a rotational shaft is rotatably provided. The width of the first opening portion in the direction of the rotational shaft is greater than the pitch (L0) of the blade at the first opening portion, and, at the downstream end of the first opening portion in the transport direction, the pitch of the blade is switched from the pitch (L0) to a pitch (L1) which is narrower than the pitch (L0). In this way, the amount of transport of the toner from the toner hopper to the development device with the transport screw is stabilized.
