Abstract:
A pen holder includes a holder to hold an electronic pen including a replaceable pen tip that contacts a screen of a display apparatus for input to the display apparatus. The pen holder further includes a pulling-out portion to pull out the pen tip, having an open end in a first direction and including a gripping portion. The gripping portion includes a first wall and a second to grip the pen tip inserted from the open end in the first direction. The first wall linearly extends in the first direction, and the second wall linearly extends in the first direction and disposed at a distance from the first wall in a second direction intersecting the first direction.

Abstract:
An abnormality detection device is configured to detect abnormality in a subject to be driven by a motor via a drive transmission member. The abnormality detection device includes an output signal acquisition unit, a rotational frequency acquisition unit, and a determining unit. The output signal acquisition unit is configured to acquire a rotational frequency output signal output from the motor. The rotational frequency acquisition unit is configured to acquire a motor rotational frequency calculated from the rotational frequency output signal acquired by the output signal acquisition unit. The determining unit is configured to distinctively determine abnormality in the subject to be driven and abnormality in the motor based on the rotational frequency output signal acquired by the output signal acquisition unit and the motor rotational frequency acquired by the rotational frequency acquisition unit.
Abstract:
A developing device includes a casing to contain developer and define a developer circulation passage, a developing roller to bear the developer, and at least one developer conveyor to convey the developer. The developer conveyor is disposed in the developer circulation passage and lower than the developing roller. The developing device satisfies M1/L2>0.56 g/cm and M1/M2>0.50, where M1 represents an amount of developer borne on the developing roller, L1 represents a width in which the developing roller bears the developer in a longitudinal direction of the developing roller; and M2 represents an amount of developer stored in the casing and excluding the amount of developer borne.
Abstract:
A developing device includes upper and lower developer containing portions to contain developer, arranged in a vertical direction, a first developer conveyor to convey developer in the upper developer containing portion to a first side in an axial direction of the first developer conveyor, a second developer conveyor to convey developer in the lower developer containing portion to a second side opposite the first side, a developer-lifting area in which the developer is lifted from the lower developer containing portion to the upper developer containing portion, a first lifting area gear to rotate the first developer conveyor, a second lifting area gear to rotate the second developer conveyor, and a lifting area input gear to input a driving force to the developing device. The lifting area input gear is coupled to the first lifting area gear and coupled via the first lifting area gear via to the second lifting area gear.
Abstract:
A developing device includes a developer bearer to bear developer, a developer containing compartment disposed lower than the developer bearer, and a conveying screw disposed in the developer containing compartment. The developing device further includes an inclined face extending from an inner wall of the developer containing compartment obliquely upward toward the developer bearer, and the inclined face opposes the conveying screw from above.
Abstract:
In a nonvolatile semiconductor memory device wherein a plurality of threshold voltages are set so as to store multi-valued information in one memory cell, data is first written into the memory cell whose threshold voltage is the lowest as a written state from the erase level, and data is successively written into memory cells whose threshold voltages are higher.
Abstract:
There is provided a separation member for separating a first conveying path formed by a first conveying member from a second conveying path formed by a second conveying member. There is also provided an opposed member facing a magnetic pole H4 at an upstream side of two magnetic poles H4 and H6 that forms a developer-releasing magnetic pole H5.
Abstract:
A powder container includes: a housing unit that is horizontally elongated, that contains powder, and that has at least part thereof being deformable; and a discharging unit that is attached to one end of the housing unit in a longitudinal direction. The discharging unit includes a discharge opening through which the powder in the housing unit is discharged outside and a rotary shutter that is provided inside the discharge opening and that opens and closes the discharge opening by rotating about a rotating shaft that is arranged perpendicular to the longitudinal direction of the housing unit.
Abstract:
A process cartridge for use in an image forming apparatus includes an image bearing member and a developing unit. The developing unit includes a developer bearing member to bear developer including toner and carrier, a casing forming a developer container containing the developer, a screw having a shaft with a spiral screw blade, a toner density sensor to detect a density of the toner on a detection surface, and a detection surface agitating member fixedly mounted on the shaft of the screw at a position facing a detection surface to scrape away the developer accumulated on the detection surface as the screw rotates. The detection surface agitating member includes an elastic sheet elastically deformable to scrape away the developer accumulated on the detection surface and disposed at a substantially same angle to an axial direction of the shaft of the screw as the spiral screw blade.
