摘要： A sheet stacking apparatus includes an ejector, a stacker, a wall, and an upper surface detector. The ejector ejects a sheet, and the stacker stacks the sheet ejected from the ejector. The wall contacts a trailing end of the sheet ejected from the ejector in an ejection direction to align the sheet. The upper surface detector detects an upper surface on a trailing end side of the sheet stacked on the stacker in the ejection direction. When the sheet moves toward the wall, the upper surface detector moves from a home position in which the upper surface detector detects the upper surface of the sheet to a retracted position in which the upper surface detector does not contact the sheet moving toward the wall.

摘要： A fold-enforcing assembly includes a fold-enforcing device, a moving device to move the fold-enforcing device in a direction of a fold of a sheet bundle, and control circuitry. The fold-enforcing device includes a pressing member pair to nip and press the fold of the sheet bundle in a direction of thickness, a pressing mechanism to pressurize and depressurize the pressing member pair, and a driver to drive the pressing mechanism. Controlled by the control circuitry, the moving device moves the fold-enforcing device in accordance with a size of the sheet bundle in the direction of the fold; pressing mechanism pressurizes the pressing member pair to press a first end portion of the sheet bundle in the direction of the fold; the moving device moves the fold-enforcing device to a second end portion of the sheet bundle; and pressing mechanism depressurizes the pressing member pair in the second end portion.

摘要： The image processing apparatus includes an RGB-YUV converter for converting a color image into a luminance signal and a color difference signal and a YUV false color remover for removing false color based on the luminance signal Y and the color difference signals U, V. The false color remover includes an edge intensity calculator for calculating edge intensity based on the luminance signal Y, a modulation coefficient calculator for calculating a modulation coefficient so that a degree of modulation is greater as the edge intensity is higher, and a UV modulator for modulating a color difference signal having a value smaller than a prescribed threshold based on the degree of modulation.

摘要： A binding device includes a stacking device configured to receive sheets, a sheet alignment member configured to align the sheets on the stacking device, a binder configured to bind the sheets on the stacking device, a binder moving device configured to move the binder, and a retreat device configured to retreat the sheet alignment member from a range of movement of the binder. The retreat device retreats the sheet alignment member in response to a pressing force acting on the sheet alignment member in a direction of movement of the binder.
