摘要:
A sheet is cut between a first conveying unit and a second conveying unit in a state in which the first and second conveying units halt and in which an upstream conveying unit conveys the sheet at a first speed; after the sheet is cut, the first conveying unit conveys the sheet at a second speed higher than the first speed to reduce a slack formed during the halting; after the sheet is cut, the second conveying unit conveys the downstream-side sheet at a third speed higher than the first speed; if the third conveying unit is nipping the sheet during cutting, the third conveying unit conveys the sheet at the third speed; and if the third conveying unit is not nipping the sheet, the third conveying unit conveys the sheet at the third speed or a fourth speed after the detecting unit detects the sheet.

PROBLEM TO BE SOLVED: To provide a method for cutting a droplet, capable of easily cutting a droplet to expose a cross section thereof, and a method for analyzing the exposed cross section of the droplet cut by the method for cutting.SOLUTION: A droplet is placed on a surface of a carbon nanotube aggregate having a plurality of carbon nanotubes, and cooled to a cooling temperature at which the droplet solidifies, or lower. Then the droplet is cut. A method for analyzing a cross section of the droplet analyzes the cross section cut and exposed by the above cutting method of a droplet.

PROBLEM TO BE SOLVED: To prevent the interference of a movable blade with paper in the course of the move of the movable blade to an open position after cutting the paper by the movable blade, and to prevent the paper from being caught by the movable blade to cause paper folds and a jam.SOLUTION: The paper cutting device is provided with: a moving mechanism 20 which moves the movable blade B from an open position X which receives the paper S fed by opening a blade tip Ba of the movable blade B in relation to the blade tip Aa of a fixed blade A and positions the movable blade B again at the open position X; an urging mechanism 35 which urges the movable blade B to the fixed blade A side so that the blade tip Ba of the movable blade B slides in relation to the blade tip Aa of the fixed blade A; and a separation mechanism 40 separating the movable blade B from the fixed blade A resisting the urging force of the urging mechanism 35 in the course of the move of the movable blade B to the open position X after the cutting of the paper S by the movable blade B. The separation mechanism 40 comprises: a cam 41 provided on the fixed blade A side; and a cam follower 42 provided on the movable blade B side and coming into contact with the cam 41.

PROBLEM TO BE SOLVED: To provide a paper cutting device that can reduce an occurrence of a cutting failure of a stack of paper by utilizing a blade rest effectively and can extend a life of the blade rest. SOLUTION: A paper cutting device has a control means controlling a stop position of a blade when cutting, the control means controlling a travel distance of the blade from a standby position to a stop position on a cutting area so as to enlarge the distance according to the increase of cutting frequency. The cutting device has a shift means to shift a blade rest member in the direction intersecting with the cutting edge of the blade, while the control means shifts the blade rest member using the shift means and to reset the travel distance up to the stop potion to an initial value when the control means determined that the travel distance up to the blade stop position exceeds a prescribed upper limit value.
