  • the light intensity of the light source 15 must be varied depending on the speed of the tapping movement in order to avoid unintentional falsification of the recorded image, for example by time-related overexposure or underexposure of the recording material, when the tapping movement is at different speeds or speeds.
  • a device provided for this purpose can be provided by means of a pickup head or light barrier 45 each running in the coordinate direction over a magnetic tape or light grid strip 47 and roller 46, which give a signal sequence corresponding to the picking speeds of the picking device 28, which is used to control the light intensity. can serve and upgraded in a device 29.
