A post-processing apparatus includes a conveyance unit, a discharge port, a tray, an elevation unit, a detection unit, and a control unit. The conveyance unit conveys a print medium supplied from an image forming apparatus. The discharge port discharges the print medium conveyed by the conveyance unit. The tray is stacked with the print medium discharged from the discharge port and can be raised and lowered in a vertical direction. The elevation unit raises and lower the tray in the vertical direction. The detection unit detects a top surface of an uppermost print medium of one or more sheets of print media stacked on the tray. The control unit controls the conveyance unit and the elevation unit and hold a relative position of the top surface with respect to the discharge port if the print medium is discharged from the discharge port at a first position. The control unit causes the conveyance unit to convey the print medium at a first speed if a discharge time from a first timing indicating the timing relating to discharge of the print medium from the discharge port to a second timing indicating the timing when the print medium is detected by the detection unit is a first time and causes the conveyance unit to convey the print medium at a second speed different from the first speed if the discharge time is a second time.

The invention relates to a recovery device (10) for recovering sample blanks (P) for a processing machine (1) for processing elements in sheet form, the processing machine (1) comprising: a plurality of work stations (300, 400, 500, 600) including at least one waste removal station (600), and a conveying device (70) comprising a plurality of gripper bars (75) configured to drive the elements in sheet form through the work stations (300, 400, 500, 600),
the recovery device (10) being characterized in that it comprises: a first removal belt (94), and a second removal belt (95) arranged after the first removal belt (94) in relation to the direction of travel (D) of the sheets, the second removal belt (94) being able to move between:
a continuous-conveying position in which first ends (94a, 95a) of the first and second removal belts (94, 95) are close together so that sheet form element waste (F) can be conveyed from the first removal belt (94) to the second removal belt (95), and
a raised position in which the first end (95a) of the second removal belt (95) has pivoted upward, creating a gap (11) between the first removal belt (94) and the second removal belt (95), so that at least one sample of blanks (P) conveyed by the first removal belt (94) tips into the gap (11). The present invention also relates to a waste removal station and a processing machine for processing elements in sheet form.

A pair of conveyance rollers are arranged for signatures. The signatures is conveyed through the pair of conveyance rollers to a stacking unit while being sandwiched from both sides thereof between the pair of conveyance rollers. In response to passage of a signature for a sheet stack through the pair of the conveyance rollers, the conveyance rollers is switched from conveyance rotation to intermittent rotation to cause the pair of the conveyance rollers to keep the signatures for a next sheet stack from being conveyed to the stacking unit. In response to the stacking unit becoming ready to receive the signatures for the next sheet stack, the conveyance rollers is switched from the intermitted rotation or the stop to the continuous rotation to cause the pair of the conveyance rollers to convey to the signatures to the stacking unit.

A method of transporting a plurality of sheet-like members containing a magnetic material includes a first step of placing one of the members on an endless belt, and a second step of releasing the member from a portion of the endless belt which is moved and folded back along a roller. The endless belt includes a first magnetic force generating portion that generates first magnetic force, and a second magnetic force generating portion that generates second magnetic force that is stronger than the first magnetic force. In the first step, the member is placed on the belt, such that a first portion of the member containing the magnetic material is located in the first magnetic force generating portion, and a second portion of the member containing the magnetic material and located rearward of the first portion in a conveying direction is located in the second magnetic force generating portion.
