Abstract: A printed sheet transporting apparatus has a sheet inlet adjustable to selected heights and including an optional inverter for incoming sheets, a sheet feed path leading to selected positions in which a deflector may be adjustably positioned for deflecting sheets to various receivers for the sheets which are mounted on the apparatus at a plurality of vertically spaced sheet receiving positions.

Abstract: A punch is disclosed in which cams at the opposite ends of a rotary shaft move a spring returned mechanism so as to apply a force to a number of punches which are aligned across a pressure plate and movable towards a die plate for punching sheets of paper fed between the pressure plate and the die plate upon each revolution of the shaft and the cams, the punches being formed and supported by the pressure plate so as to progressively enter the sheet of paper to allow for a reduction in the motor force required for performing a punching operation.

Abstract: A main printer that prints the cut papers fed from the paper feeding part and a support printer that prints and ejects the fed cut papers. The transporting part of the support printer has a cut paper transporting mechanism and a transporting control device. The cut paper transporting mechanism has a transporting route that transports the cut papers from the main printer to the inlet of the paper exit of the support printer or to the support printer and another transporting route that transports the cut papers exiting the support printer. It also has a transporting device that transports cut papers along the transporting routes. The transporting control device establishes the transporting route based on the given transporting destination specifying information and drives the transporting device.

Abstract: A sheet receiving and stacking apparatus has an infeed tray to which sheets are sequentially fed with their printed side facing upwardly starting in order, sheet one to the last sheet of a set or job, and continuing through the last sheet of the set or job, the trailing end of successive sheets being elevated and progressively moved upwardly to form a stack of sheets commencing with the first fed sheet with the last fed sheet of a set or job at the bottom and stacked on an upper run of a sheet elevating device which provides a stacker for stacking sets or jobs in sequential order with the first fed sheet of each set or job on top.

Abstract: A sorter mailbox has a sheet transport for moving sheets through a feed path to a set or sets of vertically spaced receiver trays having sheet deflecting gates which are actuated so as to sowing toward or into an open sheet deflecting position so as to contact with light spring pressure a sheet moving through the sheet feed path but to open to deflect the sheet into a selected tray from the sheet feed path.

Abstract: A base cabinet for an electronic printer has facilities for feeding sheets of paper from the base to a printer resting on the base and selectively for a) returning printed sheets to the base for stacking; b) inverting printed sheets exiting the printer and passing them to a receiver; c) passing sheets or envelopes exiting the printer straight through to a receiving tray; and d) feeding sheets exiting the printer upwardly to a sorter or mailbox.

Abstract: A moving bin sorter of the type in which the trays are individually and collectively moved vertically relative to a sheet inlet location and opened to provide an enlarged sheet entry space for receiving the sheets, has cams and counterbalancing springs to lift the trays supported in a support structure which maintains the trays in parallel relation, thereby maintaining equal spacing for printed sheet storage along the complete effective length of the trays. In one form, the support structure is a unit moved upwardly by the springs, and in another form, the support structure has a member integrated with the tray housing and a cooperative member moved upwardly by the springs, the trays being supported at all times in parallel relation.

Abstract: There is provided a plate carrier mechanism A having an endless plate belt 3 hung on between a pair of pulleys 2p and 2q spaced from each other, and a blanket carrier mechanism B having an endless blanket belt 5 hung on between a pair of pulleys 4p and 4q spaced from each other, the blanket carrier mechanism B is adapted to be displaceable to a pressure-contacting position Pp or a separating position Pr to the place carrier mechanism A, also, a speed of an outer surface of the plate belt 3 is made greater than that of the blanket belt 5, and the plate carrier mechanism A is of a driving side and the blanket carrier mechanism B is of a driven side, and the plate carrier mechanism A and the blanket carrier mechanism B are connected to each other through a rotation transmitting gear mechanism 6 having a predetermined play which can absorb a difference of the speed of the outer surface of the plate belt 3 and the speed of the outer surface of the blanket belt 5.

Abstract: A moving bin sorter of the type in which the trays are individually and collectively moved vertically relative to a sheet inlet location and opened to provide an enlarged sheet entry space for receiving the sheets, has trays displaced in a manner which controls and allows them to move parallel to each other at all times. Alignment and registration units have steel rule type members oppositely extensible into the enlarged sheet entry space with pads on the ends thereof conforming in shape to the enlarged sheet entry space for aligning the edges of various sizes of sheets and moving sets of sheets laterally of the trays to a stapler and returning the stapled sets towards the center of the trays.

Abstract: Slave rollers 5x, 5y and 5z are attached to a co-axis of a treating roller, and releasing cams 8x, 8y and 8z contacting with the slave rollers 5x, 5y and 5z for separating the treating roller from the plate carrier 2 when a protruding portion protruding above the plate carrier 2 passes through the treating roller, so that the treating roller having contacted with the rotating carrier plate 2 is released from the plate carrier 2.

Abstract: A continuous sheet stacker and finisher apparatus and method are disclosed in which sets of sheets delivered from a sheet printer or copier are collected at an assembly station, moved to a stapling position and finished prior to deposit on a stack of previously finished sets. The set assembling continues during movement of a previously collected set to the stapling station and then to a stacker in which the finished sets are collected during the period of time that a printer or copier is supplying a new set of sheets to the sheet assembly station.

Abstract: The vertical stack of trays in a movable tray sorter for sheets of paper exiting a .?.copies.!. .Iadd.copier .Iaddend.is moved in a manner to enlarge the spacing between consecutive pairs of the trays to accept consecutive sheets of paper by moving the trays along a pair of helical coils, each of which has a turn of relatively coarse pitch. The turns of relatively coarse pitch are located at the copier paper chute and causes an increased separation of adjacent trays only at that position as the coils are turned. .Iadd.The coils support the trays approximately midway between the ends of the trays in a sheet feeding direction and the sorter has vertically extended guides at opposite sides of the trays adjacent one end in which side portions of said trays slide to maintain the trays substantially parallel. .Iaddend.
