A sheet feeding device includes a driving transmission member, a feeding unit, and a switching member. The feeding unit is detachable from the sheet feeding device and includes a driven transmission member that receives a driving force from the driving transmission member, a feeding member, and a holding member that holds the driven transmission member and the feeding member. The switching member abuts the holding member and moves the feeding member between a second position and a first position lowered from the second position. When the driving force is transmitted to the driven transmission member, the feeding unit is positioned to the sheet feeding device by receiving a positioning force in an attachment direction of the feeding unit. When the driving force is not transmitted to the driven transmission member, the feeding unit is regulated by the switching member in movement in a direction opposite to the attachment direction.

A stacking apparatus for value documents, having a stack deposit device and a braking device which is arranged along the transport path of the value documents immediately before the stack deposit device. On the transport shaft of the braking device at least one driving roller is firmly mounted and at least one roller rotatably supported on the transport shaft. At least one cam roller is firmly mounted on a braking shaft of the braking device and at least one eccentric roller. By a rotation of the braking shaft, the eccentric roller can electively be brought in engagement with the opposing driving roller so that a value document becomes clamped between these, or be brought out of engagement with the opposing driving roller, so that the value document is no longer clamped between these, but rather is brakable by the engagement between the cam roller and the rotatably supported roller.

An automatic document feeding device includes a conveyance unit, an image reading unit, a color reference member, a moving assembly, and a drive source. The drive source includes a rotation output shaft to drive the conveyance unit and the moving assembly. The drive source changes the rotation output shaft from a forward rotation direction to a reverse rotation direction to reversely rotate the rotation output shaft to a set reverse rotation angle set in advance, according to a condition of conveyance of the document. In a rotation transmission route from the rotation output shaft to the moving assembly, the movement regulator is disposed in a first reverse rotation drive region from when a rotation direction of the rotation output shaft is changed to the reverse rotation direction to when a rotation angle of the rotation output shaft after the change in the reverse rotation direction reaches the set reverse rotation angle.

The present disclosure is in one aspect to a dispenser for rolled sheet materials. The dispenser includes a feed roller that is rotatably mounted to a housing of the dispenser housing, and that is configured to feed a predetermined amount of sheet material from the supply of sheet material through a discharge provided along the housing of the dispenser. The dispenser also has a feed roller drive assembly with a drive motor, and a belt transmission assembly. The belt transmission assembly has a drive belt coupled to the drive motor and to the feed roller such that rotation of the feed roller is driven by operation of the drive motor.

A sheet conveying apparatus includes first and second drive sources, first and second driving units, each including a respective first or second roller to convey a sheet, an operating unit, and a switching unit to switch a state of the sheet conveying apparatus between a first state in which the first driving unit and the second driving unit are not connected to each other and a second state in which the first driving unit and the second driving unit are connected to each other. A first drive source driving force drives the first driving unit. A second drive source driving force drives the second driving unit. The operating unit rotates when manually operated. In the second state, operating unit rotation is transmitted to the first driving unit to rotate the first roller, and operating unit rotation is transmitted to the second driving unit to rotate the second roller.

A rope based fall protection device including a rotation unit, a brake unit, and a rope. A first end of the rope is connected to the rotation unit. The rope includes a first rope loop and a second rope loop that are wound around the rotation unit. A first retaining portion of a retaining ring is sleeved on the first rope loop and a second retaining portion thereof is sleeved on the second rope loop, such that the rope forms a rope section which has a fixed length between the second retaining portion and the first end and is wound around the rotation unit. When a free end of the rope is pulled by an external force to release the rope wound around the rotation unit in a direction away from the rotation unit, the retaining ring is broken to release the rope section of the rope. The external force is greater than or equal to a pulling force generated by a user's free fall. By releasing the rope section of the rope, the rotation unit rotates and simultaneously drives the brake unit to rotate to slow down or stop the rotation of the rotation unit.

An image forming system has a transmission assembly, standard and auxiliary sheet feeders, standard and auxiliary trays, an image forming device and a controller. The transmission assembly is for switching transmission of a drive force of a motor selectively to the one of the standard and auxiliary sheet feeders. The controller determines whether sheet is absent in the standard tray. The controller, based on determining the sheet is absent in the standard tray and receipt of preceding data, control the transmission assembly to initiate to switch the transmission of the drive force to the auxiliary sheet feeder. Also the controller, based on receipt of control data received after preceding data, control the image forming device to form an image based on the control data.
