    Abstract: An electrographic printer device for printing tape-shaped recording media (10) in duplex and simplex printing contains two transfer printing stations (15/1,15/2) that can be pivoted against and away from the photoconductive drum (11). The first transfer printing station (15/1) serves for transferring toner images allocated to the front side, the second transfer printing station (15/2) serves for transferring back side toner images. A mechanical buffer storage (29) and a turn-over means (28) with preceding intermediate fixing station in the form of a photoflash fixing station (31) are arranged between the transfer printing stations (15/1,15/2).

    Abstract: The invention relates to a sheet curl control apparatus including a decurler (350) for reducing the curl in sheet material passing therethrough and adjusting means coupled to the decurler (350) for adjusting the decurling action of the decurler (350). Sensing means (406) in the form of an infra-red emitter (408) and two infra-red detectors (410 and 412) are employed for sensing the extent of any residual curl left in the sheet material after it has passed through the decurler (350), and for feeding a signal indicative of the residual curl to control means, conveniently including a stepper motor, for automatically adjusting the adjusting means, for example a rack and pinion arrangement, thereby to alter the decurling action of the decurler (350) in a predetermined manner. The sheet curl control apparatus is described in relation to its use in a copier for duplex copying.

    Abstract: An image forming system carries out a simplex recording operation for forming an image on one side of recording paper and discharge the paper onto a discharge tray, and a composite or duplex recording operation in which image-carrying recording paper is formed with a further image on the same image-carrying side or a reverse side prior to discharge. This system includes a paper refeeding device for temporarily storing the recording paper after the simplex recording and refeeding the recording paper to an image forming device for recording a second image thereon, and a mode selector for selecting between a page arranging mode and a non-page arranging mode. The recording paper is discharged directly onto the discharge tray when the non-page arranging mode is selected. On the other hand, when the page arranging mode is selected, the recording paper is transported through the paper refeeding device and recording section and out to the discharge tray.

    Abstract: This specification discloses a sheet conveying apparatus having piling means for piling sheets with a predetermined amount of deviation in the direction of conveyance provided therebetween, first conveying means for imparting a conveying force to only that surface of the lead-off one of the sheets piled with the predetermined amount of deviation provided therebetween which is not in contact with the other sheets, and movement restricting means disposed upstream of the first conveying means by a distance shorter than the predetermined length of the conveyed predetermined sheet minus the predetermined amount of deviation for restricting the movement of the other sheets than the lead-off sheet. The specification also discloses a sheet conveying method characterized by the step of piling sheets successively with a predetermined amount of deviation in the direction of conveyance provided therebetween, imparting a conveying force in the direction of conveyance to the lead-off of the piled sheets, and conveying the other sheets than the lead-off sheet in the direction opposite to the direction of conveyance.
