An image forming apparatus includes: a housing having an opening; a drum configured to rotate around a rotation axis to convey a medium in a conveyance direction; an image former configured to form an image on the medium on the drum; a reader downstream of the image former in the conveyance direction, the reader configured to read the image on the medium formed by the image former; a first space accommodating the reader; a second space downstream of the first space in the conveyance direction; a path between the first space and the second space; and a shield configured to openably close the path. The image former and the reader are radially arranged with respect to the rotation axis of the drum.

Image forming apparatus, image reading device, and liquid discharge device

An image forming apparatus includes a housing having an opening; a drum configured to rotate around a rotation axis to convey a medium in a conveyance direction; an image former configured to form an image on the medium on the drum; and a reader downstream of the image former in the conveyance direction, the reader configured to read the image on the medium formed by the image former. The image former and the reader are radially arranged with respect to the rotation axis of the drum. The reader is drawable from the opening of the housing along the rotation axis of the drum.

An image reading device includes a plurality of readers, an access opening, and a lift. The plurality of readers read an image on a recording medium. The plurality of readers are arranged around a carrier to rotate while carrying the recording medium on a peripheral surface of the carrier. The plurality of readers are arranged radially about a rotation axis of the carrier. The plurality of readers are to be introduced through the access opening. The lift includes a cable to lift one reader of the plurality of readers introduced through the access opening. The lift lifts and locates the one reader at a predetermined height position around the carrier with the cable.

Method and mechanism of attaching readers, and image reading device

A reading device and an image forming apparatus. The reading device includes a reader disposed at a scanning position, the reader being configured to read an image formed on a surface of a sheet, a movement mechanism to move the reader between the scanning position and a separated position away from the scanning position, and a reference plate disposed at a first position facing a reading face of the reader, the reference plate being configured to obtain a reference value to be used when the reader reads the image. In the reading device, the reference plate rotates around an axis from a second position facing a side of the reader to the first position or from the first position to the second position in conjunction with movement of the reader from the scanning position to the separated position by the movement mechanism The image forming apparatus includes the reading device.

Reading device and image forming apparatus

A waste liquid collector includes a waste liquid tank, a rotatable member, and a cover. The waste liquid tank is removably inserted in the waste liquid collector, the waste liquid tank configured to collect waste liquid. The rotatable member is configured to rotate with removal or insertion of the waste liquid tank. The cover is configured to contact a waste liquid inlet portion of the waste liquid tank to cover a waste liquid inlet portion, the cover being slidable with respect to the rotatable member.
