Abstract
A device for electro-optical point and line scanning of contone and line originals. A contone scanning unit for scanning a contone original and a line scanning unit for scanning a line original are provided. A mechanical switch-over unit comprising a mirror is arranged within a beam path of a scanning beam preceding the contone scanning unit and the line scanning unit. The mechanical switch-over unit selectively occludes either the contone scanning unit or the line scanning unit from the scanning beam for selectively scanning the contone original or a line original.
Claims15
A device for point-by-point and line-by-line optoelectronic scanning of an original, comprising:
- a contone scanning means for scanning a contone original;
- a line scanning means for scanning a line original;
- said contone scanning means and said line scanning unit each having at least one scanning channel;
- a mechanical switch-over means comprising a mirror;
- and
- said mechanical switch-over means being arranged within a beam path of a scanning beam preceding said contone scanning means and said line scanning for selectively occluding either said contone scanning means or said line scanning means from the scanning beam for selectively scanning the contone original or the line original.
A device for point-by-point and line-by-line opto-electronic scanning of an original, comprising:
- a contone scanning unit for scanning a contone original;
- a line scanning unit for scanning a line original;
- said contone scanning unit and said line scanning unit each having at least one scanning channel;
- a mechanical switch-over unit comprising a mirror;
- said switch-over unit being arranged within a beam path of the scanning beam preceding said contone scanning unit and said line scanning unit;
- and
- said mechanical switch-over unit having a positioning structure connected thereto for selectively placing the mirror within said beam path for selectively occluding either said contone scanning unit or said line scanning unit from the scanning beam for selectively scanning the contone original or the line original.
A device for point-by-point and line-by-line opto-electronic scanning of an original, comprising:
- a contone scanning means for scanning a contone original;
- a line scanning means for scanning a line original;
- said contone scanning means and said line scanning means each having a given number of scan channels;
- a switch-over means for selective connection of either the contone scanning means or the line scanning means;
- and
- both the given number of scan channels associated with the contone scanning means as well as the given number of scan channels associated with the line scanning means being allocated to a respective common single multiplier serving both the contone scanning means and the line scanning means for each scan channel.
A device for point-by-point and line-by-line opto-electronic scanning of an original, comprising:
- a contone scanning means for scanning the contone originals;
- a line scanning means for scanning a line original;
- said contone scanning means and said line scanning means each having a given number of channels;
- a switch-over means for selective connection of either the contone scanning means or the line scanning means;
- and
- four multipliers being provided with each multiplier being optically coupled to one of the scan channels of the contone scanning means and the line scanning means.
A device for point-by-point and line-by-line opto-electronic scanning of an original, comprising:
- contone scanning means for scanning a contone original;
- a line scanning means for scanning a line original;
- said contone scanning means and said line scanning means each having a same given number of output channels at which light signals are output;
- a plurality of opto-electronic converters equal to said given number, each of the opto-electronic converters being optically coupled to one of said output channels of said line scanning means and one of said output channels of said contone scanning means, said opto-electronic converter converting light signals from the output channels to corresponding color signals;
- and
- switch-over means for causing light outputs either from the contone scanning means or the line scanning means to said opto-electronic converters.
