A printing apparatus includes a printing portion that performs printing on a medium, a cutting portion that is capable of moving in a movement direction and that has cutting blades that cut the medium and a housing unit that holds the cutting blades, and a contact portion provided at a position at which the contact portion comes into contact with the housing unit when the cutting portion moves in the movement direction.

A post-processing device includes a sheet transporting section that transports one or more sheets, a cutting section that cuts the sheet along a transporting direction of the sheet being transported by the sheet transporting section and a paper piece transporting section that transports a paper piece cut by the cutting section, and a transporting speed of the paper piece transporting section is set lower than a transporting speed of the sheet transporting section.

A sheet processing system conveys a material sheet in a first direction; calculates an inclination angle of the first registration mark of the material sheet with respect to the first direction; and includes cutting blades configured to cut the material sheet to produce sheet pieces and a cutting direction adjustment mechanism configured to adjust a cutting direction to a direction of the inclination angle. The sheet processing system conveys the sheet piece in a second direction; and includes a guide member configured to extend in the second direction and to guide a cutting end of the sheet piece, a processing place position identification section configured to identify a position on a conveyance path of a processing place of the sheet piece based on the inclination angle, and processing mechanisms configured to perform processing on the processing place whose the position on a conveyance path is identified.

An apparatus for processing a flexible material (14) comprises: a first roller (5) extending along a main axis (A1); a second roller (6) extending along a longitudinal axis (A2), the first roller (5) and the second roller (6) being mutually co-operating to carry out an operation on the flexible material (14), an interspace (37) being defined between the first roller (5) and the second roller (6) though which the flexible material (14) can pass; a pressing device for pushing the first roller (5) and the second roller (6) one towards another; a position adjustment device for adjusting the relative position of the first roller (5) and the second roller (6), the position adjustment device being distinct from the pressing device.

In order to reliably cut a sheet even when the width of the sheet is changed while shortening cutting time, the position of an end portion of the sheet is sensed and a cutting range is set according to the sensed position of the end portion.

A card-cutting apparatus, provided with a lateral cutter portion to cut paper in a lateral direction at right angles with a transferring direction and plural slitter heads to cut the paper in the transferring direction, to conduct divisional cutting of the paper into plural cards in which the plural slitter heads are disposed in a row along a guiding rod set in the lateral direction as to be freely position-adjusted in lateral direction by manual work, a gauge plate, for positioning of the plural slitter heads on predetermined positions in the lateral direction as to cut the paper with a predetermined card cutting lateral dimension, is provided, and the gauge plate is selected from plural kinds having different card cutting lateral dimensions to be used.

A cutting apparatus comprises a cutting unit including a first blade member and a second blade member that cooperates with the first blade member in cutting an object, configured to cut the object by moving the object and at least one of the first and second blade members relative to each other in a cutting direction; and a changing unit configured to change a crossing angle between the first blade member and the second blade member during an operation of cutting the object, wherein the changing unit makes the crossing angle after the start of the cutting smaller than the crossing angle at the start of the cutting.

A cutting apparatus includes a cutting blade that cuts a medium and a casing that holds the cutting blade. The casing has a first passageway in which the medium passing through contacts the cutting blade and a second passageway in which the medium passing through does not contact the cutting blade.

A laminated film including an adhesive layer peelably laminated on a base film is shear cut using an upper roller including specific upper blades arranged at a pitch of 0.5 mm or less for slitting. The upper blade includes one side surface constituting a blade edge being a flat surface and the other side surface having a first ridge and a second ridge from the blade edge aide. A laminated tape including an adhesive layer peelably laminated on a base film is slit by slitting using this upper blade to a tape width of 0.5 mm or less without the base film and the adhesive layer peeling apart and with suppressed protrusion of the adhesive layer in the slit tape.

A sheet cutting device including first and second rotating blades that mesh with each other at inner and outer positions in an axial direction and that cut a sheet, and a restoring unit. When a positional relationship between the inner and outer positions of the first and second rotating blades in the axial direction is reversed, the restoring unit releases the first and second rotating blades from each other and moves at least one of the first and second rotating blades in the axial direction to restore the positional relationship between the inner and outer positions to an original state.
