  • Patent number: 11845624
    Abstract: A conveying device includes a rotating carrier, an inlet rotary body, an outlet rotary body, a downstream conveyor, and an inching controller. The rotating carrier carries a sheet. The inlet rotary body transfers the sheet to the rotary carrier from upstream of the rotary carrier in a conveyance direction of the sheet. The outlet rotary body transfers the sheet to a downstream area from the rotary carrier in the conveyance direction. The downstream conveyor conveys the sheet downstream from the outlet rotary body in the conveyance direction. The inching controller performs an inching operation to convey the sheet on a conveyance path including at least the downstream conveyor. The inching controller causes at least the outlet rotary body and the downstream conveyor to perform a conveying operation in conjunction with each other in the inching operation.

  • Publication number: 20230131241
    Abstract: A conveyance apparatus includes a conveyor and processing circuitry. The conveyor conveys a sheet. The processing circuitry controls conveyance of the sheet by the conveyor and switching a direction in which the conveyor conveys the sheet to a direction opposite to a direction in which the sheet is ejected, after the conveyance of the sheet is stopped under a predetermined condition.

  • Publication number: 20230037177
    Abstract: A conveyance apparatus includes a bearing rotator, an entrance rotator, an exit rotator, a first driver circuit, a downstream conveyor, a second driver circuit, and a recording medium detector. The entrance rotator receives a recording medium at a first position. The downstream conveyor receives the medium at a second position. As a process of removing the medium, the first driver circuit starts rotation operation after the second driver circuit starts driving the downstream conveyor and rotates the rotators for not less than a period of time for the medium to be conveyed from the first position to the second position. The second driver circuit continues driving the downstream conveyor for not less than a period of time for the medium to be conveyed from the second position to a position at which the medium is detected after the rotation operation of the first driver circuit is stopped.

  • Patent number: 10792936
    Abstract: A coating device includes a coating member, a nip forming member, a pair of conveying members, and circuitry. The nip forming member forms a coating nip together with the coating member. The pair of conveying members is opposed each other to nip and convey a recording medium to the coating nip. The circuitry is configured to cause the pair of conveying members to release nipping of the recording medium at timing when a leading end of the recording medium reaches the coating nip.
