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.

Collator

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. While the collator processes the copies of a certain document under any one of the collate, job separation and non-collate modes, for instance the collate mode, any one of the job separation and non-collate modes, for instance the job separation mode, to be effected for copies of the next document can be reserved, and the collator is automatically switched from the collate mode into the reserved job separation mode upon completion of the previous collate mode.

Collator with collate mode, non-collate mode and job separation mode

In an automatic document feeder for use in combination with an electrophotographic copying machine for feeding documents successively into the copying machine by separating and feeding the documents one by one from a stack of documents, the stacked documents are placed on a document table and are fed by a pair of rollers into a nip portion between a rotating separation roller and a separation plate having a rubber sheet applied thereto to separate and feed documents one by one from the lowermost one, and an edge detecting sensor for detecting a front edge of a document is arranged downstream with respect to the separation roller to produce an edge detection signal. When the edge detection signal is produced, the relevant document is once stopped at the front edge detecting sensor and after a start signal for denoting the completion of a copying operation for the preceding document is supplied from the copying machine, the relevant document standing by the front edge detecting sensor is advanced. An opening for manually inserting a document is provided at a downstream position with respect to the front edge detecting sensor and a rotatable lid is provided above the opening.

A collator includes a series of twenty bins arranged in parallel with each other, a copy feeding member for feeding copies supplied from a copying machine along inlets of the successive bins, first and second deflecting devices arranged at the uppermost two bins for delivering the copies into the uppermost two bins and a distributor movable between the third bin and the twentieth bin for delivering the copies into the bins. 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.

Collator with collate mode and job separation mode

An electrophotographic apparatus particularly suitable for printing a plurality of duplicated copies from each of a plurality of sheet-like documents comprising a sheet-like document feeding device for feeding the sheet-like document at a constant velocity, an optical system including an illumination lamp and a projecting lens for exposing and scanning the document during the traveling of the document, a photosensitive drum for forming a latent image corresponding to the document image and retaining the latent image for a relatively long time period, a device for developing the latent image with toner particles, a device for transferring the toner image onto a record paper and a device for fixing the toner image on the paper. After the latent image has been once formed on the photosensitive drum the given number of duplicated copies are formed by repeatedly effecting the development, transfer and fixing operations. The document can be set in the document feeding device while the duplicating operation for forming a plurality of copies for the previous document is carried out.

Electrophotographic apparatus

An apparatus for controlling a facsimile transmitter and receiver in which operations at a receiving end are automatically effected in succession by a control signal delivered from a sending end. The transmitter functions to deliver a continuous '1' signal. The receiver functions to automatically start its operation when the continuous '1' signal continues for a time longer than a predetermined time. The transmitter comprises a manuscript detector. When the front end of a manuscript to be transmitted is detected a phase signal is delivered. The receiver comprises a detector and a discrimination circuit. When the phase signal is detected, a record sheet is delivered and recorded and when depletion of the phase signal is detected, a cutter is operated to cut the record sheet. The distance between the front end of the manuscript and a reading head is made equal to the distance between the front end of the record sheet and a recording head.
