A document dispenser capable of dispensing documents from a plurality of separate bins is constructed of a modular design. The dispenser is constructed by assembling the modules, one for each bin, with each module including an input hopper and a document feeder. The modules are connected together to feed the documents along a common delivery feed path to a stacker which is provided on a module on the dispensing end of the device.

A document encoder is described, which is conceived as a compact desk set. In order to serve as a multi purpose unit and in spite of that exhibit a compact type of construction, the various printing devices (2, 4, 6, 7, 8) and print backings (41, 42; 47; 55; 64, 71) impacting the document from its front- and back side are arranged stationary in a chassis (1), while the printing process in direction of the lines is accomplished solely through conveying the document by means of a conveyor device. ...

A carrier for conveniently storing, transporting and viewing documents, such as blueprints, is provided through two durable, pliable flaps affixed to one another at one end, between which the documents are placed. The bottom flap is longer than the top flap so that when in an unrolled state for viewing the documents, the free end of the bottom flap may be turned over to rest on the documents to retain them in a flat, unrolled, easily viewable position even in the presence of wind gusts. The flap...

A document holder for an assembly of loose leaf sheets, such as computer printouts, including a channel member provided with a slot defining a track for slidably and separably receiving at least one binder element secured to the sheet assembly, wherein the binder element is detachably snapfitted to the sheet assembly through aligned apertures formed in corresponding perforated margin portions of the sheets.

Document counter with discharge means comprising a support for a wad of documents, an endless conveyor belt which can be moved about a rotational axis, means for guiding the conveyor belt in the plane of the support to engage the lowermost document on the support, and collecting means comprising a flap wheel system which can be rotated about a rotational axis which is parallel to the rotational axis of the conveyor belt, flaps extending from the periphery of the flap wheel system, said flaps for...

A document reader contains a document display window for focussing the light reflected from the surface of a given manuscript thereon, a scale formed on the document display window and provided with a cursor capable of being moved in the direction of main scanning, means for freely controlling the shift of a reading line on the manuscript in the direction of sub-scanning, and means for automatically sensing the position of the cursor and the position of the reading line on the manuscript and adm...

A document scanner includes a wedge-shaped scanner housing (16, 18), vertically movable on a main housing (10) to locate an inclined scanned window against a document resting on a trough-like document support (14) beneath the scanner housing. The scanner housing is manually movable up and down for location against and removal from a document to be copied, and counterbalancing means are provided within the main housing to facilitate such vertical housing movement.

A reference light from a reference reflective surface is projected onto an image sensor to form an output signal from the image sensor corresponding to the distribution of a reference light. This output signal is stored in a memory as a reference signal used for shading correction. An output signal from the image sensor corresponding to a document image is corrected in accordance with the reference signal. Irrespectively of whether or not the document is being read, the image sensor is irradiate...

A document feeder, which is swingably arranged on a copying machine, which senses the position of the document on the copying table of the machine. When the document has travelled a predetermined distance, as monitored by a plurality of Hall effect sensors arranged on the motor which operates the document feeder, the motion of the document is terminated and the copying sequence begun. A special control circuit calculates the distance that the document has moved in response to the signals receive...

A device as described for indicating the state of focus of an image of a document which is converted into a video signal by sequentially inspecting the incident light level at points within the image and generating an electrical signal having a parameter which varies with the light level. The device includes: (a) circuit responsive to the electrical signal from sequential inspection of the image for integrating the amplitude variations thereof to produce a varying amplitude focus indication sign...
