Abstract: An endorser for document processing machines is provided with means for controlling the application of an endorsement in a manner which reduces the deleterious effects of impaction previously encountered when printing endorsements and at the same time affords certain other advantages. The system employs camming means operating through lever means to control the impact in a manner which converts a point load to a shear load while reducing power requirements to a driving motor and making it possible to cope with documents of varied thicknesses. The system makes it possible to convert some of the energy otherwise wasted in the system to accelerate the platen and thus reduce motor power requirements.

Abstract: An envelope feeder which can be mounted on a printer having a rotatable platen and a printing head for automatically feeding, printing and stacking envelopes is disclosed. It has a blank envelope feeding hopper from which blank envelopes are extracted one at a time and fed by a transporting roll and belt mechanism to the printer platen for printing. The position of the envelope is sensed when it reaches the printer platen and the transporting mechanism stopped for printing of the envelope by the printing head. After printing is completed, the transporting mechanism is reactivated to deliver the printed envelope to an envelope receiving hopper for stacking in sequence with other printed envelopes.

The correction label applying device is detachably secured to the body of the portable label printing machine. The price tag holding device of the label applying device is provided with adjusting means in which the positions of stoppers which receive the tip edge portion of an inserted price tag and the positions of a pair of guides which guide both the side edges of the inserted price tag can be changed. A leaf spring gives elastic force to the price tag holder.

Abstract: A drive system for processing passbook data includes a bi-directional stepper motor responsive to programmed input signals, cam sets rotated by the stepper motor for initiating data sensing, document positioning, and data transfer operations, and cam followers actuated by the contour of their associated rotating cam sets for moving their reacting components to perform those operations. Appropriate cam followers cause a pressure plate and sensor to move toward and sense coded data on a document, a gate to open and close to position the document for further processing, and a print platen to advance toward the document, provide a backing during data transfer, and then retract.

Abstract: Disclosed is a means for feeding unit documents, such as sheets, envelopes, pages, cards, and the like to an apparatus for processing. Means is provided for feeding the documents to and removing them from the operating apparatus at a relatively high rate of speed. During the time that an individual document is being operated upon it is conveyed by means associated with the operating apparatus. Examples of such operations would be printing addresses on an envelope, embossing credit cards, encoding magnetic tapes, and the like. Upon conclusion of the operation, the documents are removed quickly so that a second document may be supplied to the operating apparatus expeditiously.

Abstract: The disclosure relates to item or document signing apparatus for imprinting a legally acceptable signature and/or date, etc., upon individual items or documents fed on demand thereto at high speed from an input to an output hopper in a stop-start operation. An adjustably positionable item stop mechanism permits the printing of the data at selectable locations along the longer dimension of the item. Both date and signature imprinting means are simply efficiently and easily demountably removable and replaceable permitting alteration and/or rapid change of the imprinted data. Novel to be automatically maintained regardless of document thickness.

Abstract: An improved printing apparatus control system regulates the operation of a sheet feed assembly which sequentially moves sheets of material to and from a printing station and a plate feed assembly which sequentially moves printing plates to and from the printing station. A photocell detects initial movement of a leading end portion of the printed sheet of material away from the printing station under the influence of the sheet feed assembly. This photocell is also utilized to detect when the printed sheet of material has completely exited from the printing station. A second photocell detects the presence of the succeeding sheet of material at the printing station. The control system also includes a sensor which detects the removal of one printing plate from the printing station, the absence of a printing plate at the printing station, and the subsequent arrival of the next succeeding printing plate at the printing station.

Abstract: Both the operative position of a movable platen and the presence of paper to be advanced past the platen in a line at a time printer are affirmatively sensed by a single mechanism. A cantilevered spring arm extending from a fixed mount includes a terminal switch sensor at its free end in proximity to the paper. At an intermediate region along its length the spring arm traverses adjacent to but spaced apart from the platen, and an adjustable set screw on the arm is disposed for contact with the platen. When the platen is in the operative position, behind the print hammers, and the printer is loaded with paper, the spring arm biases the actuator into contact with the paper, transferring the switch contact to a given position and thereby indicating that both needed prerequisites for printer operation are satisfied.

Abstract: A document feeding apparatus sequentially feeding documents, including an automatic feeder for removing one document at a time from a stack and for delivering each document to a feed path. An endless conveyor moves each document along the path towards a document aligning gate means that temporarily interrupts the movement of the documents to effect desired alignment thereof. The automatic feeder and the document aligning gate are automatically controlled so that the documents are selectively removed from the stack as a function of the preceding document moving along the path. A pair of printing heads are positioned along the path and are respectively actuated in response to movement of the documents so that the documents can be printed at accurately positioned locations on a surface thereof.

Abstract: A line printer for printing successive lines of information on a ticket. As the ticket is guided toward ticket printing and advancing mechanisms, a first ticket sensor energizes a latch circuit and shifts the ticket advancing mechanism from a normally closed condition to an open condition. The ticket then moves freely into the printer to a predetermined position defined by a stop. A second ticket sensor at the stop is then actuated to close the ticket advancing mechanism and enable ticket advancement.

Abstract: A document positioning device is provided having a document holder or carrier which is driven by a stepper motor to position a document clamped therein for printing thereon. A row of light sources, e.g. light emitting diodes (LEDs) are pre-positioned and spaced along the path of travel of the document holder so that each source corresponds to a line to be printed on the document. A photosensor is mounted on the document holder for scanning the LEDs. The LED is lit for the selected line to be printed and the stepper motor moves the document holder, scanning the LEDs until coincidence occurs, stopping the motor. A memory is coupled to the motor control circuit of the stepper motor which is activated on coincidence to force the motor control circuit into the proper output for a selected line. For manual operation the LEDs are continually cycled, and the document holder manually moved to the selected line with the power to the motor off.
