Definitions

  • a device for generating such a reference pulse is already known from DE-OS 195 16 154.
  • the device has a stationary light source which generates a light beam directed onto a rotating object.
  • the light beam is reflected by a mirror on the rotating object on a 2
  • the light beam (4) generated in the optical signal transmitter (1) falls in that angular position of the shaft (7) in which the optical axis (5) of the light beam (4) with the optical axis (15) of the objective (12) and Slit diaphragm (13) coincides through the gap (14) of the slit diaphragm (13) on the optical sensor (6).
  • the optical sensor (6) thus generates an electrical reference pulse, also called "start-off-line pulse” or SOL pulse for short, once per revolution of the shaft (7), which detects a defined angular position of the shaft (7).
  • the light source (1) is preferably a single-mode light source, for example a laser diode.
  • a photodiode can be used as the optical sensor (6).
  • the collimator (3) can be used as an achomat or as a plano-convex or 4
  • Fig. 2 shows an application example of the device according to the invention for position detection in an inner drum recorder.
  • a recording material (16) to be exposed is fixed on the inner surface of a stationary half-shell or exposure trough (17).
  • the pixel-by-line exposure of the recording material (16) takes place through the light beam (4), which is brightness-modulated with the information to be exposed.
  • the light beam (4) is guided by a light beam deflection device (18) coupled to the rotating shaft (7) pixel by line and line by line over the recording material (16), the beginning of each line on the recording material (16) using the once per Rotation of the shaft (7) in a defined angular position of the shaft (7) generated SOL pulse is signaled.
  • the position detection method (7) is in the area of the shaft (7) Fig. 1 is present, which generates the SOL pulse.
