  • Publication number: 20220203710
    Abstract: An image forming apparatus includes a housing, a feeding tray inserted into and pulled out from the housing, an image forming unit, and first and second guide members. The feeding tray includes a first accommodation part in which a roll body having a configuration where a sheet-shaped medium is rolled in a roll shape is accommodated and a second accommodation part in which stacked sheet-shaped media are accommodated. The first guide member guides a sheet-shaped medium to a conveying path. The second guide member guides a roll medium unrolled from the roll body to the conveying path. The second guide member is movable between a guide position for guiding the roll medium to the conveying path, and a retreat position further distant from the first guide member than the guide position and where the second guide member does not interfere with a sheet-shaped medium accommodated in the second accommodation part.

  • Publication number: 20220150373
    Abstract: An image processing apparatus includes a motor, a sheet feeding roller, a separation roller, a conveyance roller, a first clutch set provided in a transmission path of a driving force transmitted from the motor to the sheet feeding roller, and a second clutch set provided in a transmission path of a driving force transmitted from the motor to the separation roller. The first clutch set includes a first one-way clutch and a first two-way clutch, and the second clutch set includes a second one-way clutch and a second two-way clutch. A maximum value of a first play angle set between a first transmission portion and a first transmitted portion in the first two-way clutch is larger than a maximum value of a second play angle set between a second transmission portion and a second transmitted portion in the second two-way clutch.

  • Publication number: 20220144570
    Abstract: A sheet conveying device includes a tray, a device body having a conveying route of a sheet and supporting the tray, a side guide supported by the tray to be movable in a first direction intersecting with a conveying direction of the sheet and contacting an end portion in the first direction of the sheet placed on the tray, a cover rotatable with respect to the device body and covering the conveying route, and a lock lever locking the cover to the device body and provided in a position overlapping the side guide in a second direction intersecting with the conveying direction and the first direction. The lock lever is rotatable between a lock position where the cover is locked and a release position where the cover is released. The side guide includes a first notched portion facing a rotation track of the lock lever with a gap.

  • Publication number: 20210070576
    Abstract: An image recording apparatus is provided, including a casing; a tray which is to be installed to the casing by being inserted in a first orientation and which is to be withdrawn from the casing in a second orientation that is opposite to the first orientation; a sheet conveying passage; a platen; a recording part; and an interlock which moves the platen while being interlocked with movement of the tray in the first orientation or movement in the second orientation. The platen is movable to a printing position and a release position. The interlock moves the platen from the printing position to the release position while being interlocked with the withdrawal of the tray from the casing or the insertion of the tray into the casing.

  • Patent number: 10281871
    Abstract: An image forming apparatus has a first opening on a side surface of the casing, first and second frames, a cartridge detachably attached through the first opening, and light receiver and light emitter respectively provided to the first and second frames. The cartridge shields the light from the light emitted when attached to an attachment position. The first and second frames face across the attachment position. The light reaches the light receiver when the cartridge is detached from the casing. A door is movably secured to the casing between closing and opening positions, and a second opening allowing a sheet to pass through is formed on the door. External light entering through the second opening and directed toward the light receiver is shielded by a light shielding part provided to the first frame, which also serves as a guiding part to guide attachment of the cartridge.

  • Patent number: 10118795
    Abstract: An image forming apparatus includes a reconveying unit including a reconveying roller; and a second transmission mechanism. The second transmission mechanism transmits a drive force to the reconveying roller and includes an input gear; an output gear; an intermediate gear including first and second gears; and first and second swinging gears. The first toothless part of the first gear and the second toothless part of the second gear are provided at such a position that, when the intermediate gear is rotated by a drive force transmitted from the input gear through the second swinging gear while the second swinging gear meshes with the second toothed part of the second gear and the output gear meshes with the first toothed part of the first gear, the first toothless part reaches a position confronting the output gear and then the second toothless part reaches a position confronting the second swinging gear.

  • Patent number: 10095158
    Abstract: A cartridge of an image forming apparatus includes a conveying member configured to convey toner from a tonner accommodating part of the cartridge to a developing device, and a switching lever configured to switch a state of the conveying member between a driven state and a non-driven state. The toner replenishment lever is movable between a first position at which the replenishment lever pushes the switching lever and a second position at which the replenishment lever is spaced from the switching lever. The contacting part is retracted to outside of a space through which the cartridge passes when attached to or detached from the attachment position. The switching lever is configured to switch the state of the conveying member between the driven state and the non-driven state depending on whether the contacting part of the toner replenishment lever is located at the first position or the second position.
