Abstract: A sheet stacking device includes a conveyance part and a stopper. The conveyance part includes a tray and a conveyance member. On the tray, sheet stacks are stacked. The conveyance member conveys the sheet stack on the tray. The stopper is located on a downstream side of the tray and prevents the sheet stack from falling from the tray. The stopper has a main plate and an anti-slip member. The main plate is inclined upward. The main plate has a contact face coming into contact with the sheet stack and a bent face bent downward from a downstream side tip end of the contact face. The anti-slip member is provided from a downstream side end portion of the contact face to the bent face. A frictional coefficient between the anti-slip member and the sheet stack is larger than a frictional coefficient between the sheet stack and the contact face.

Abstract: The sheet post-processing device includes a discharge port, a discharge tray, a first sheet holding member, and a second sheet holding member. The discharge port has a pair of discharge rollers that discharge a sheet including a folded sheet subjected to folding processing. The first sheet holding member and the second sheet holding member are, on a downstream side of the pair of discharge rollers in the discharge direction of the folded sheet, selectively disposed at a holding position, at which the first sheet holding member and the second sheet holding member intersect a discharge route for the folded sheet and extend downward from above the pair of discharge rollers toward the discharge tray to hold the folded sheet, and a retreat position retreated to above the discharge route for the folded sheet.

Abstract: A sheet folding device includes a folding rollers pair, a folding blade, a movable guide, and a driving mechanism. The folding rollers pair includes a first roller and a second roller, and causes a sheet conveyed in a first conveyance direction to pass through a first nip area between the rollers. The folding blade is selectively disposed in a folding position and in a retracting position. The movable guide can reciprocate between a covering position covering the second roller disposed downstream of the first roller in the first conveyance direction and the first nip area and a non-covering position exposing the second roller and the first nip area. The drive mechanism disposes the folding blade in the folding position while disposing the movable guide in the non-covering position, and disposes the folding blade in the retracting position while disposing the movable guide in the covering position.

Abstract: A sheet postprocessing device includes a sheet conveying passage, a sheet tray, an inlet guide, a processing device, and a blowing device. Though the sheet conveying passage, a sheet on which an image has been formed is conveyed. The sheet tray is arranged downstream of the sheet conveying passage and has sheets stacked on it. The inlet guide is arranged at the downstream end of the sheet conveying passage and guides a sheet to the sheet tray. The processing device performs predetermined processing on a sheet stacked on the sheet tray. The blowing device blows air, from the upstream side in the sheet conveying direction, between the top face of the top-most sheet in the sheets stacked on the sheet tray and the bottom face of the subsequent sheet sent from the inlet guide into the sheet tray.

Abstract: The sheet discharge device includes: a sheet discharge part; a sheet discharge tray having a tray upper surface and a rear wall portion; a fullness detection sensor for detecting that a height of a stack surface of folded sheets; and a first sheet presser member and a second sheet presser member for pressing a rear end side and a fore end side in a discharge direction, of the folded sheet. In a first pressing position in which the first sheet presser member extends from above the detection sensor to below the detection region, and is brought into contact with the folded sheet of a minimum size stacked on the tray upper surface. When a stack number of the folded sheets has exceeded a specified number, the first sheet presser member is retracted upward from the first pressing position by the rise of the stack surface.
