  • Publication number: 20250053119
    Abstract: A process cartridge includes a photosensitive member unit with a photosensitive drum, a developing unit detachably mounted on the photosensitive member, and a toner cartridge detachably mounted on the developing unit. The toner cartridge has a holder including a protruding portion on an end side thereof, and the developing unit is provided with a rotatable lift member on an end side thereof. In a mounted state in which the toner cartridge is mounted on the developing unit, the toner cartridge is maintained in the mounted state by engaging of a first portion of the lift member with the protruding portion, and the toner cartridge is transited from the mounted state to a lifted state in which the toner cartridge is rotated upward by contacting of a second portion of the lift member to the protruding portion with rotation of the lift member.

  • Patent number: 12204274
    Abstract: A developing cartridge includes: a casing configured to accommodate therein toner; a developing roller; a supply roller configured to supply the toner to the developing roller; a layer thickness regulation blade in contact with a circumferential surface of the developing roller; a developing electrode electrically connected to the developing roller; and a supply electrode electrically connected to the supply roller and the layer thickness regulation blade. The supply electrode includes: an electrode member electrically connected to a rotation shaft of the supply roller and movable in a direction perpendicular to the rotation shaft; and a connection member in contact with and electrically connecting the electrode member and the layer thickness regulation blade. The electrode member is movable relative to the connection member in the direction perpendicular to the rotation shaft in a state where the electrode member is in contact with the connection member.

  • Publication number: 20230130570
    Abstract: Provided is a power conversion device with which a region in which an electronic component is mountable in a first printed wiring board of a first substrate can be enlarged. The power conversion device includes a power module installing member, a power module, a bus bar assembly, a first substrate provided on the bus bar assembly, and a second substrate provided on the bus bar assembly. The first substrate includes a first printed wiring board, and a signal terminal connector and a first board-to-board connection connector which are each provided on the first printed wiring board. The second substrate includes a second printed wiring board and a second board-to-board connection connector provided on the second printed wiring board. The signal terminal connector is connected to a signal terminal of the power module. The first board-to-board connection connector and the second board-to-board connection connector are connected to each other.

  • Patent number: 11588423
    Abstract: An electric-power conversion apparatus has a heat sink in which one side portion out of a pair of side portions that extend in a direction perpendicular to the axial direction of a motor is formed shorter than the other side portion thereof; a lower case to which the heat sink is fixed is fastened to a driving apparatus through the intermediary of fixing portions at the both end portions of each of the pair of side portions of the heat sink or at respective positions in the vicinity of the both end portions of each of the pair of side portions of the heat sink; at least one of a reactor and capacitors is disproportionately disposed to be closer to said one side portion than to said the other side portion of the heat sink.

  • Patent number: 8347209
    Abstract: According to the present invention, when a style relating to a dimension of all elements included in a subtree of a structured document is set in a relative unit, all these elements can be displayed in the same style. The user terminal 100 allocates a drawing area to each key when drawing each key configuring a key string of a tree structure, determines a root of a subtree to which a specific key belongs when a style whose format relating to dimension is expressed in the relative unit is set to the key, and converts the style expressed in the relative unit into an absolute unit with the drawing area allocated to the root of the subtree as reference and draws the key according to style expressed in the absolute unit.

  • Publication number: 20050129199
    Abstract: An input device having touched position detecting means for outputting a signal indicating a touched position during a period of time of touch when the touched position detecting means is touched, wherein a character and a symbol are inputted to be displayed on a display screen. Provided are: a virtual keyboard in which each virtual key corresponding to a plurality of characters or symbols is arranged corresponding to each divided area on the touched position detecting means; means for outputting, during the period of time of touch, a code signal indicating a character or a symbol of a virtual key corresponding to an area including the touched position; means for temporarily displaying on the display screen a character or a symbol of the outputted code signal; and means for determinately displaying the character or the symbol on the display screen when the code signal has disappeared.
