  • the lowermost sensing element 50 carries on a cantilever 70 a threaded rod 72 made of soft magnetic material which is aligned in the direction of displacement and which rests on a door-fixed steel pin 74 made of hardened steel which projects vertically inward beyond the sliding door.
  • the steel pin forms the core of an induction coil 76 and is premagnetized via a permanent magnet 78 (FIG. 4).

  • a comparison cycle is initiated in which the value set of the buffer store is compared with the reference value sets of the reference memory. If a match is found, i.e. if a valid bottle is found, the associated bottle deposit is paid out in accordance with the reference value set, the turnstile motor is started to take the bottle into the bottle receiving chamber and then the input chamber is released again. If no valid bottle is found, the empty bottle determined to be defective remains in the input chamber and must be removed from it before inserting a new empty bottle.
