Abstract: In a collator for use in combination with an electrophotographic copying machine which discharges copies of originals in succession at the same time interval, deflection claws for delivering successive copies of a manuscript into successive bins are provided at inlets of respective bins and two endless belts each having an actuator for driving the deflection claws are provided movably along the successive bins. The two endless belts are driven by two different controlling circuits, respectively in an independent manner. During the copy delivering operation by the first endless belt for a plurality of copies of a certain document, it is possible to initiate the copy delivering operation by the second endless belt for a plurality of copies of the next document.

Abstract: A collator includes a series of twenty bins arranged in parallel with each other. A copy feeding member feeds copies supplied from a copying machine along inlets of the successive bins. First and second deflecting devices are arranged at uppermost two bins for delivering the copies into the uppermost two bins. A distributor is movable between the third bin and the twentieth bin for delivering the copies into the bins. An extra tray is provided separately from the bins. The collator further comprises a collate mode selecting member, a job separation mode selecting member and a non-collate mode selecting member.

The collator can treat the copies in a job separation mode in which all copies of each documents are delivered into respective bins in succession, while the distributor is advanced bin by bin in response to a distributor advance signal produced by a variable timer which is actuated upon detection of the rear edge of the last copy of an Nth original by an entrance switch to set a time period represented by b+(N-1).times.a/V.sub.1, wherein a is a pitch between successive bins, b is a distance from the entrance switch to the first bin and V.sub.1 is a copy feed speed in the collator.

Abstract: An electrophotographic sensitizing screen having a great number of apertures, wherein at least an insulating layer and a conductive layer are successively formed on a conductive mesh, is disclosed. These apertures are regularly arranged at such an angle as not to produce moire fringes with respect to a light image projected on the screen.

Abstract: A copying machine includes a shutter mechanism comprising a light shield member which intercepts the incidence of extraneous light onto a photosensitive drum through an exposure window, and a detecting member which is operated by a cover which forms a conveyor unit for a sheet-shaped original or by a book carrier on which a thick original is placed. A movement of the light shield member into or out of an exposure light path is controlled by the operation of the detecting member.

Abstract: A photosensitive screen for an electrographic apparatus adapted to modulate a flow of corona ions by an electrostatic latent image produced thereon is disclosed. The photosensitive screen is composed of an electrically conductive mesh which is coated on one side with an insulating layer and an electrically conductive layer superimposed one upon the other in the order as mentioned and coated on the other side with a photosensitive layer.The photosensitive screen comprises further an insulating thin film layer which covers at least the electrically conductive layer for the purpose of protecting it against surrounding atmosphere and hence improving durability thereof.
