摘要： A cassette is attachable to an image forming apparatus including a feed roller. The cassette is provided with a push-up member for pushing up leading edges of sheets placed in the cassette so as to bring the uppermost one of the contained sheets into contact with the feed roller, and a restricting member for restricting displacement of the contained sheets from a specified position. By attaching thus constructed cassette to the image forming apparatus, sheets can be fed properly by the feed roller.

摘要： A sheet feeder includes a feeder for feeding a sheet, a cassette for containing a plurality of stacks of small sized sheets side by side therein, the cassette including a plurality of biasing members for biasing the respective stacks of small sized sheets upwards so as to bring uppermost sheets of the respective stacks into contact with the feeder, a plurality of sheet detectors arranged in positions corresponding to the respective stacks of sheets for detecting the height of the respective stacks of sheets contained in the cassette, and a controller responsive to the plurality of sheet detectors for determining the absence of sheet in the cassette when at least one of the plurality of sheet detectors detects that the height of the stack has become lower than a predetermined height, and stopping a sheet feeding operation. This sheet feeder prevents the transfer device of an image forming apparatus from being smeared due to the fact that the small sized sheet is fed from only one stack.

摘要： A copy item transport device is used in an image forming apparatus having an image bearing member and a pair of registration rollers before the image bearing member, and includes a separator for regulating multiple copy items to one copy item for each image formation. The separator is constructed by a forward roller being driven in a forward direction of transporting the copy item to the registration roller pair, a reverse roller in contact with the forward roller. The reverse roller is driven in a reverse direction of transporting the copy item backward, but rotatable in the forward direction together with the forward roller when receiving a greater transmitted forward torque from the forward roller than the reverse torque. The reverse drive to the reverse roller is stopped at the same time or after the forward drive to the forward roller is stopped to assure the nip of copy item by the registration roller pair.

摘要： A discharge device is usable for an image forming apparatus including a fixing portion having a heating roller in the shape of a hyperboloid for fixing a toner image formed on an envelope having a turned-up portion, and a stacking portion for stacking envelopes. The discharge device provided with a discharge roller system provided between the fixing portion and the stacking portion to discharge the envelope to the stacking portion has a upright portion provided near the discharge roller system below the transport path of the envelope to prevent the turned-up portion of the envelope from warping downward. This discharge device prevents a discharging envelope from coming into contact or colliding with the uppermost one of a stack of already discharged envelopes on the stacking portion, and enables the envelopes to be discharged suitably and to be stacked orderly on the stacking portion and increases an amount of envelopes stacked on the stacking portion.

摘要： In a time period from the time point where the forward end of a paper sheet fed from a pair of paper separation rollers reaches a registration roller to the time point where the registration roller is driven, when the load torque exerted on a forward roller is not less than second regulated torque, the transmission of power to the forward roller is released by a torque limiter provided for the forward roller. In this case, therefore, the force of paper feeding produced by the pair of paper separation rollers is regulated. Consequently, a suitable force of paper feeding can be applied to the paper sheet, thereby to make it possible to regulate the paper sheet straight in the direction of paper feeding as well as to prevent the paper sheet from continuing to be fed even if the amount of deflection of the paper sheet is saturated between the pair of paper separation rollers and the registration roller to prevent the paper sheet from being wrinkled.
