  • Patent number: 11027938
    Abstract: A medium transport device includes a transporting member, a medium offsetting member, a guide member, and an interlocking member. The guide member is located upstream of the transporting member in a medium transport direction. The guide member is movable between a first position, in which the guide member guides the medium toward the medium accommodating member, and a second position, in which the guide member guides the medium to a destination different from the medium accommodating member, to guide the medium. The interlocking member moves the guide member between the first position and the second position in conjunction with a movement of the medium offsetting member in a width direction of the medium offsetting member.

  • Publication number: 20200102176
    Abstract: A medium transport device includes a transporting member, a medium offsetting member, a guide member, and an interlocking member. The transporting member transports a medium toward a medium accommodating member. The medium offsetting member moves the transporting member in a medium width direction to transport the medium to the medium accommodating member at positions shifted in the medium width direction. The guide member is located upstream of the transporting member in a medium transport direction. The guide member is movable between a first position, in which the guide member guides the medium toward the medium accommodating member, and a second position, in which the guide member guides the medium to a destination different from the medium accommodating member, to guide the medium. The interlocking member moves the guide member between the first position and the second position in conjunction with a movement of the medium offsetting member in a width direction of the medium offsetting member.

  • Patent number: 9932193
    Abstract: An image forming apparatus includes an image forming section, a reverse transport portion that transports the recording medium in a reverse direction, which is opposite to a transport direction in which the recording medium is transported to the reverse transport portion from the image forming section, a first ejection portion to which the recording medium is ejected and that is disposed on a downstream side of a second transport path in the transport direction, the second transport path diverging from a first transport path along which the recording medium is transported from the image forming section to the reverse transport portion, and a reverse transport path along which the recording medium is transported from the reverse transport portion to the image forming section, the reverse transport path not overlapping a third transport path along which the recording medium is transported from the image forming section to the first ejection portion.

  • Patent number: 9829847
    Abstract: A recording medium transporting device includes a transport path, a first open-close portion, and a second open-close portion. A recording medium on which an image is formed is transported over the transport path. The first open-close portion is disposed on a side surface of the transporting device so as to be openable to cover and closeable to uncover the transporting device. The first open-close portion renders a first portion of the transport path open when the first open-close portion is opened so as to uncover the transporting device. The second open-close portion is located inside the transporting device at a position further inward of the first open-close portion so as to be openable to cover and closeable to uncover the transporting device. The second open-close portion renders a second portion of the transport path open when the second open-close portion is opened so as to uncover the transporting device.

  • Patent number: 9811045
    Abstract: An image forming apparatus includes: a communication unit that receives first mode electric power to perform communication; an image forming unit that receives first mode electric power to form an image on a medium; a fixing unit that generates heat by receiving first mode electric power, and performs a fixing process of fixing the image to the medium; a predicting unit that predicts a processing time required for a process of forming the image; and a supply controller that controls supply of electric power according to a first mode or a second mode in which power consumption is smaller than that of the first mode. The supply controller starts the supply of first mode electric power to the fixing unit at a timing based on the predicted processing time when the image forming apparatus transitions from the second mode to the first mode.
