  • Patent number: 8925918
    Abstract: A conveying apparatus has a first conveying roller pair; a second conveying roller pair; a first conveying path through which a sheet is conveyed in such a manner that the first conveying roller pair is placed downstream of the second conveying roller pair; and a second conveying path through which the sheet is conveyed in such a manner that the first conveying roller pair is placed upstream of the second conveying roller path. A circumferential velocity of at least one of the first conveying roller pair and the second conveying roller pair is switched so as to meet conditions, i.e., |Va|>|Vb| when the sheet is conveyed through the first conveying path and |Va|?|Vb| when the sheet is conveyed through the second conveying path. Here, |Va| is an absolute value of the circumferential velocity of the first conveying roller pair, and |Vb| is an absolute value of the circumferential velocity of the second conveying roller pair.

  • Patent number: 8870183
    Abstract: An image forming apparatus includes a plurality of rotary members, a conveyance belt, an image forming device, and a switchback device. The conveyance belt is looped around the plurality of rotary members so as to circulate to intermittently feed a sheet in a sheet transport direction. The image forming device is disposed opposing the conveyance belt to form an image on the sheet fed by the conveyance belt. The switchback device is disposed downstream from the image forming device in the sheet transport direction to feed the sheet having passed the image forming device to a position downstream from the conveyance belt in the sheet transport direction and switch back the sheet. When the sheet is fed by the conveyance belt and the switchback device, a drive start timing of the switchback device is delayed from a drive start timing of the conveyance belt.

  • Patent number: 8844922
    Abstract: A sheet processing apparatus which enables a sheet to be stopped at a target position with precision even when the sheet is stopped by moving a heavy unit such as a shift unit. A drive unit moves a moving unit so as to move a sheet, which is being conveyed, in a direction perpendicular to a conveying direction of the sheet. An output unit detects movement of the moving unit and output a signal in synchronization with movement of the moving unit. A control unit issues a stop instruction to the drive unit based on a delay time from when a start instruction to the drive unit is issued until when the signal in synchronization with the movement of the drive unit is output, and a target moving amount required for the moving unit to move to a target position.

  • Patent number: 8838008
    Abstract: A device for switching a transport direction of a recording material includes a switching unit and a movement unit. The switching unit switches a transport direction of a recording material by being selectively moved to a first position or a second position. The movement unit moves the switching unit between the first position and the second position by increasing or reducing a force exerted on the switching unit. The movement unit changes, on the basis of a temperature of the movement unit, timing at which the force exerted on the switching unit is increased or reduced.

  • Patent number: 8787816
    Abstract: Disclosed is an image forming apparatus. The image forming apparatus includes a housing having a discharge port, a plurality of photosensitive bodies mounted in the housing, a transfer unit to transfer visible images formed on the plurality of photosensitive bodies onto a printing medium, a fusing unit to fuse transferred visible images to the printing medium, and a reverse unit to reverse a moving direction of the printing medium, after the printing medium has passed through the fusing unit. As the moving direction of the printed printing medium is reversed by the reverse unit, the printing medium may be discharged while a printed surface of the printing medium is directed downward, allowing a user to easily draw out the printing medium.

  • Patent number: 8746685
    Abstract: Disclosed is a printing apparatus that can prevent the occurrence of a transport error and prevent useless printing even when the sheet size of the actually fed sheet is different from the sheet size specified in the printing setting. The printing apparatus forms an image on one side of a recording medium first and then forms an image on another side of the recording medium. A determination section determines the medium length of the recording medium, and a control section causes the recording medium to be ejected to a sheet ejection port after the image is formed on the one side of the recording medium, when the determined medium length is outside of a preset threshold range.
