An electrostatic recording head includes a plurality of elongated head chips fixed on a head base in a linear alignment along their longitudinal direction. The head chip has a dielectric layer, a plurality of line electrodes provided on one surface of the dielectric layer and extending at predetermined intervals in the longitudinal direction, and a plurality of finger electrodes provided on one surface of the dielectric layer and arranged to cross the line electrodes to together form a matrix. A control electrode or electrodes are provided to face the finger electrodes through an insulator layer. The finger electrodes extend parallel to an end face of the head chip.

An electric charge generator for use in an apparatus for producing an electrostatic latent image includes a plurality of charge generation controlling devices, each charge generation controlling device including: an insulating substrate; a line electrode formed on the insulating substrate; a solid dielectric film formed on the surface of the line electrode; a finger electrode having a hole for generating an electric charge, the hole being formed in the central part of the finger electrode, the finger electrode being formed on the solid dielectric film; a solid insulating film having a hole for passing the electric charge, the hole being formed in the central part of the solid insulating film, the solid insulating film being formed on the finger electrode; and a screen electrode having a hole for ejecting the electric charge, the hole being formed in the central part of the screen electrode, the screen electrode being formed on the surface of the finger electrode via the solid insulating film; wherein the plurality of charge generation controlling devices are arranged on the insulating substrate so as to form the electric charge generator. The solid insulating film is formed of a multilayer solid insulating film including a surface-side layer made of an inorganic insulating film and a substrate-side layer made of an organic insulating film whereby the durability and the reliability are improved.

An original conveying apparatus includes a follower roller unit which is moved to its deployed position to define an extension of an original conveying path over the upper surface of the copying machine when a book carrier is used in order to convey an original having substantial thickness. A follower roller holding member is disposed within the unit and moves in interlocked relationship with the movement of the unit to its deployed position so as to maintain the follower roller in its position projecting above an original guide surface when the unit is moved to its deployed position.

Original conveying apparatus for electrophotographic copying machines

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

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.
