Stapling apparatus used for stapling copy sheets into booklets produced from documents copied in repeated cycles which includes a tray mechanism having movable side guide members capable of receiving different size sheet material fed along a predetermined path from a processor. The sheet material is stopped by a gate mechanism which is positioned adjacent to the tray mechanism and is operative to move from one position in the sheet path to a second position out of the sheet path in response to discrete electrical signals. The stapling assembly is operative to drive staples one staple at a time into each pile of sheets collected and held in registration by the tray mechanism and gate mechanism in response to electrical signals. A solenoid actuated eject roll mechanism is used to eject the stapled pile of sheets after the gate mechanism has been lifted out of the gate path and move the staple pile to the receiving tray. A control circuit supplies the signals necessary to carry out the program logic of the various components of the stapling apparatus in timed relation.
An apparatus for ejecting stapled sets of sheets sidewise includes a freely rotatable driven wheel, a drive wheel, means for driving said drive wheel, means for positioning the driven wheel on one major surface of the collated sets of sheets, means for positioning the drive wheel on the opposite side of the major surface opposite the driven wheel, means for moving the drive wheel against the driven wheel whereby the collated set of sheets are ejected sidewise by frictional force. There is further provided a stapling apparatus and control means for integrating the operation of the stapling and ejecting functions in a high speed copier/duplicator whereby each of a plurality of collated sets of sheets are stapled and ejected in succession.
An apparatus in which a plurality of sheets are stapled to one another. The stapling frequency is dependent upon the number of sheets being stapled together. The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to be limiting as to the scope of the invention in any way.
An apparatus in which at least two sheets are stapled to one another. The apparatus includes a controller which places a pressure source in communication with a staple drive so that pressurized fluid actuates the staple drive to drive a staple through the sheets. Thereafter, the controller places the staple drive in communication with a staple clincher so that the pressurized fluid exhausting from the staple drive actuates the staple clincher to clinch the portion of the staple legs protruding through the sheets.
A transfer roller which transfers a toner image to a recording sheet fed in a gap between a photoreceptor drum and the transfer roller, and a pre-transfer guide which guides the recording sheet are pushed to be displaceable by a spring by use of a roller so that a predetermined gap is maintained between the photoreceptor drum and the transfer roller and that the positions of the transfer roller and the pre-transfer guide depend on the position of the photoreceptor drum. The recording sheet P on which an image has been transferred is conveyed to a conveying guide. A post-transfer guide which receives the abutment of the end of the image transferred recording sheet and guides the recording sheet to the conveying guide is provided to be displaceable integrally with the transfer roller and the pre-transfer guide. The post-transfer guide is made of a resin with a resistance of 10.sup.10 .OMEGA. to 10.sup.16 .OMEGA..
An apparatus in which a stack of sheets is brought into contact with the clamping surface of a fixed stapler head. After the stack is secured against the clamping surface, a staple is driven therethrough.
