  • Patent number: 7887054
    Abstract: A sheet transport direction switching device includes: a rotary guide member having a single guide passage for passing a sheet to be transported, and a support shaft extending in a direction orthogonal to a transport direction of the sheet; and a posture changing mechanism for changing the posture of the rotary guide member. The rotary guide member is operable to change the posture thereof by pivotal movement about an axis of the support shaft so that an exit of the guide passage faces one of at least two discharge destinations. The posture changing mechanism has a stepping motor for pivotally moving the rotary guide member about the axis of the support shaft.

  • Publication number: 20090309288
    Abstract: A recording medium conveying device including a body portion capable of being mounted to and removed from a body of an apparatus, the body portion being provided with a conveying roller; a knob member disposed at a side at which the body portion is removed, the knob member allowing manual rotation of the conveying roller; and a handle member for mounting the body portion to and removing the body portion from the body of the apparatus. The handle member is rotatably supported so as to move between a first position and a second position, The knob member is connected to a rotating shaft of the conveying roller so as to move along a direction in which the body portion is removed. The handle member moves between the first position and the second position in response to an accommodation operation and a draw-out operation of the knob member.

  • Publication number: 20080292349
    Abstract: An image forming apparatus includes an image bearing member with an image bearing surface adapted to move in a given direction and carry a toner image thereon. A main cleaning device is opposed to the image bearing surface and electrically removes residual toner remaining on the image bearing surface. A power supply is adapted to apply to the main cleaning device a bias having a polarity reverse to a charge polarity of the residual toner. An auxiliary cleaning device is provided near and upstream of the main cleaning device with respect to the moving direction of the image bearing surface and can be brought into contact with the image bearing surface. A support structure supports the auxiliary cleaning device and permits the auxiliary cleaning device to be moved swingingly while following a displacement of the image bearing surface during the moving.

  • Publication number: 20080205945
    Abstract: A guiding roller unit has a holder to be mounted on a mount, and a guiding roller rotatably supported by the holder. The holder includes a base, two bearings and widening preventing plates attached respectively to the bearing. The base, the bearings and the widening preventing parts are integral to each other. The base is mounted on the mount. The bearings stand from opposite ends of the base and rotatably support the roller. The widening preventing plates extend in directions opposite to facing directions of the bearings. The holder enables the roller to be attached and detached with leading ends of the bearings elastically widened with respect to base ends thereof connected with the base while being detached from the mount, whereas it prohibits widening of the leading ends of the bearings by contacting the mount in response to forces acting in widening directions while being mounted on the mount.

  • Publication number: 20060255528
    Abstract: A sheet separating/conveying mechanism 30 has an upper unit 30a in which a paper feed roller 31 and other components are arranged and a lower unit 30b in which a separating roller 32, an arm member 36, and other components are arranged. The arm member 36 is U-shaped as seen in a plan view by being composed of a left and a right movable lever 36a that are mutually parallel and that make contact with both ends of a center shaft 23b and a pivot shaft 36b that supports the movable levers 36a so that they are rotatable in a direction indicated by arrow BB?. The movable levers 36a have locking holes 39 formed at the tip ends thereof, and the lower ends of tension springs 38 are locked in those locking holes 39. The lower unit 30b is fitted with an applied force adjusting member 45 on which locking portions 42a and 42b are formed to protrude therefrom leftward and rightward that permit adjustment of the positions at which the upper ends of the tension springs 38 are locked.
