  • Patent number: 4515470
    Abstract: An apparatus, such as in a copying machine, by which an original sheet and a light-sensitive sheet can be fed along separate feed paths toward and onto one another and then one upon another through a station for exposure of the light-sensitive sheet to a light image of the original sheet is provided with a control system, including a separating device disposed to act on the sheets passing from the exposure station, whereby after an exposure the original sheet can be led away from the light-sensitive sheet irrespective of the relative position of the sheets fed for the exposure. A detector sensing the leading edge of an original sheet in its own feed path, activates the control system which in turn puts the separating device into operation after the lapse of a period of time corresponding to the time of transport of the leading edge of the original sheet from the detector up to the separating device.
