Abstract: A card cutter for producing a plurality of cards by cutting a sheet is provided, wherein a pair of rotary shafts rotating in directions opposite to each other are provided with a sheet feeding path between them. A plurality of first rotary blades are arranged on the one rotary shaft, while a plurality of second rotary blades are arranged on the other rotary shaft so that they slide in contact with each other between the peripheral edges so as to constitute a slitter cutting portion. A roller for pressing each end of the sheet outside the slitter cutting portion is provided at least at the one rotary shaft.

Abstract: A multifunction punch apparatus, which can arbitrarily set a sheet size and a punch hole number and punch accurate punch holes with right and left margins of a sheet balanced, wherein information as to the sheet size, a punching direction, and the punch hole number is input from a manipulation panel to a controller; a traveling of a timing belt on which a head is mounted is controlled by controlling a control motor disposed in a manipulation unit cover to determine a movement position of the head; a sheet inserted between a punch guide unit and a guide member is punched by moving a hole punch vertically through a gear and a punch drive gear by driving a spline shaft; and when lengths of the right and left margins of the sheet in which a predetermined number of holes are punched are different, the length of the left margin is corrected by manipulating increase/decrease switches to correct a position of a first punch hole from a left side of the sheet.

Abstract: This invention provides a card cutting apparatus having a function capable of reliably peeling off trash sandwiched between two rotating disc blades of a slitter cutting section of the card cutting apparatus and capable of discharging the trash outside. A tip end of a guide member having a guide surface for discharging the trash is inserted close to a second rotation shaft or boss between thin blades, thereby peeling off the trash sandwiched between the thin blades and allowing the trash to fall along the guide surface of the guide member.

Abstract: A binder with the plurality of binding portions (curl rings, etc.) has indication(s) such as projection, hollow, paint, etc. at each end of the binder or both ends thereof enabling users to quickly and simply identify a direction of the binder to bind papers without errors. Users can identify the binding direction only through visibly or tactilely confirming the indication(s) thus improving efficiency of binding operations.
