Abstract: A paper folding apparatus for a binding machine, capable of discharging paper sheets by folding the paper sheets twice, includes a first knife unit and a second knife unit. The first knife unit has a first feeding path and a pair of first paper folding rollers. The second knife unit has a second feeding path and a pair of second paper folding rollers. A paper arranging guide is installed in front of the pair of first paper folding rollers, and the second knife unit includes a pinion, a rack selectively engaged with the pinion, a rack guide configured to provide a path on which the rack is moved, a resilient member resiliently supporting the rack, and a second paper folding knife configured to move back and forth between the second paper folding rollers in association with a moving direction of the rack.

Abstract: Disclosed is a memory system which includes a nonvolatile memory device configured to store data information; and a memory controller configured to control the nonvolatile memory device. The memory controller provides the nonvolatile memory device with a program command sequence including program speed information according to an urgency level of an internally requested program operation.

Abstract: Disclosed is a stapling apparatus having an improved structure capable of smoothly rotating a stapler at both lateral sides of the stapling apparatus. The stapling apparatus includes a base frame including a horizontal slot, branch slots branching from the horizontal slot, rotation restricting plates protruding from a branch portion between the branch slots and the horizontal slot, respectively, and a movement guide shaft provided in parallel to the horizontal slot, a movable frame movable to a left or a right on the base frame, and a bucket for rotating a stapler, in which a pair of first guide rollers fitted into the horizontal slot and a second guide roller protruding to an outside of the horizontal slot are fixed to a lower portion of the bucket, and one of the first guide rollers is guided to move to the branch slot from the horizontal slot.

Abstract: Disclosed is a paper discharge apparatus of optimizing the moving path of a stapler provided at the rear of the paper discharge apparatus by effectively constructing the structure of the paper discharge apparatus that discharges paper onto a stacker tray. The paper discharge apparatus includes a pair of guide side plates including first rail grooves and curved cams adjacent to the first rail grooves, a pair of paper gripping units to grip the paper on the paper stacking plate in the contact with the curved cams, a first driving unit to drive the paper gripping units, an aligning stopper provided between the guide side plates to straightly move by a predetermined distance in the paper transfer direction from front end portions of the guide side plates, and a second driving unit to previously move the aligning stopper in the paper transfer direction just before the paper gripping units.

Abstract: Disclosed is a paper suppressing device capable of improving paper alignment while safely discharging papers onto a stacker tray. The paper suppressing device includes a clamp holder shaft, a clamp on the clamp holder shaft, a crank arm to open the clamp fixed onto the clamp holder shaft, and a driving wheel driving the crank arm. A control mass, which includes a fixing member protruding from the clamp holder shaft perpendicularly to the clamp holder shaft, a pin provided perpendicularly to an end portion of the fixing member, and a lever protruding in adjacent to the fixing member, is fixed onto the clamp holder shaft. The crank arm has one end portion with a slit groove engaged with the pin of the control mass in such a manner that the pin is movable, and an opposite end portion eccentrically coupled with a rotational shaft of the driving wheel.

Abstract: Disclosed is a paper mixing preventing apparatus which prevents a paper sheet stacked on a paper buffering unit, a paper arranging unit, or a stacker tray on a paper feeing path and a succeeding feeding sheet from being out of sequence. A lower unit and an upper unit are installed between a stacked paper sheet and the succeeding paper sheet. A pressing plate of the upper unit and the support plate of the lower unit move, so the support plate of the lower unit is rotated together with the pressing plate to prevent the succeeding paper sheet from being damaged. The associated movements of the lower unit and the upper unit are released at a position where the pressing plate of the upper unit is moved, and the lower unit primarily returns to its initial state and the upper unit returns to its initial state subsequently.
