A stacker includes a medium stacking portion for receiving and stacking a medium processed and discharged by a processing unit, a medium butting portion for aligning the medium by contacting a leading end of the medium, and a paddle that includes a feeding portion and is for transporting the medium received by the medium stacking portion in a direction toward the medium butting portion by rotating. Furthermore, the stacker has a first mode in which the paddle stops in a state in which the feeding portion does not contact the medium on the medium stacking portion and a second mode in which the paddle stops in a state in which the feeding portion comes into contact with the medium on the medium stacking portion and is deformed.

A trolley device is used to convey laminar elements. The trolley device includes at least one belt that defines a closed loop, a plurality of pulleys, at least one drive pulley being configured to act on the belt, the pulleys being mounted on a frame with a supporting region over which a section of the belt can be slid and wherein suction means linked to the belt are provided. The belt includes at least on the outer face thereof a projecting section of predetermined length that protrudes in height with respect to the rest of the belt, the projecting section being provided with a plurality of through holes aligned in position with through holes made in the belt.

A conveying apparatus includes a conveyor and a conveyed object receptor. The conveyor includes a conveyance surface facing downward and configured to convey a conveyed object having a sheet-like shape. The conveyed object receptor is arranged below the conveyor and configured to receive the conveyed object having fallen from the conveyor.

An image inspection device has a first suction conveyance unit which is arranged on the upstream side with a conveyance surface as an upper surface, a second suction conveyance unit which is arranged on the downstream side with a conveyance surface as a lower surface to make the conveyance surface continuous from the upstream side, a first inspection section which inspects an image on a front surface of an inspection object which is conveyed to the first suction conveyance unit and a second inspection section which inspects an image on a back surface of the inspection object which is conveyed to the second suction conveyance unit. The inspection object is conveyed in a state of being sucked and held on the first and second suction conveyance units and therefore is stable in position and posture in conveyance and an expected accuracy is maintained in inspection performed by the first and second inspection sections.

A medium transporting apparatus includes a transport belt that has a loop shaped, a cling mechanism that causes the medium to cling to the transport belt, a rotation mechanism that transports the medium by rotating the transport belt, a plurality of detection units that detect an transport direction end of the medium, a controller that corrects a skew of the medium, and a stacker on which the medium transported by the transport belt is stacked, in which the plurality of detection units are arranged at positions that are on an upstream side of the transport belt in the first transport direction and that are different from each other in a width direction, and the controller corrects, according to a result of the detection by the detection units, the skew of the medium in a state of being cling to the transport belt.

A conveying apparatus includes a conveyor and a conveyed object receptor. The conveyor includes a conveyance surface facing downward and configured to convey a conveyed object having a sheet-like shape. The conveyed object receptor is arranged below the conveyor and configured to receive the conveyed object having fallen from the conveyor.

An image forming apparatus includes a transfer unit, a fixing unit, a first conveyance unit which includes a first conveyance rotator, a first suction fan, and a first suction port, a second conveyance unit which includes a second conveyance rotator, a second suction fan, and a second suction port, and a control unit. The control unit is configured to execute a first mode of changing a rotational speed of the second suction fan from a first rotational speed to a second rotational speed lower than the first rotational speed after a leading edge of the sheet passes through the fixing unit in a case where a sheet having a length longer than a length from the fixing unit to a downstream end of the first suction port in the sheet conveyance direction is conveyed.

During flipping sheets may fold upon themselves under the influence of gravity. To prevent a sheet stacker is provided with a holding device for releasably holding at least a portion of the sheet at least partially during the flipping of the sheet by a sheet flipping device, wherein the holding device is configured for movement of the held portion of the sheet in a first direction perpendicular to the flipping axis.

An image forming apparatus includes a transfer unit forming a transfer nip portion, a fixing unit forming a fixing nip portion, and first and second belt suction conveyance units to suck a sheet onto a first belt and a second belt, respectively. The fixing nip portion is arranged at a position above the transfer nip portion. In a sheet conveyance direction, an upstream end portion of the first belt in the first belt suction conveyance unit is provided below the transfer nip portion, a downstream end portion of the first belt is provided above an upstream end portion of the second belt in the second belt suction conveyance unit, and a downstream end portion of the second belt is provided below the fixing nip portion. The first and second belts are inclined from a lower position to an upper position from upstream to downstream in the sheet conveyance direction.

A stacker includes a medium stacking portion for receiving and stacking a medium processed and discharged by a processing unit, a medium butting portion for aligning the medium by contacting a leading end of the medium, and a paddle that includes a feeding portion and is for transporting the medium received by the medium stacking portion in a direction toward the medium butting portion by rotating. Furthermore, the stacker has a first mode in which the paddle stops in a state in which the feeding portion does not contact the medium on the medium stacking portion and a second mode in which the paddle stops in a state in which the feeding portion comes into contact with the medium on the medium stacking portion and is deformed.
