<p>PURPOSE:To prevent erroneous detection even after specified delay by comparing a correct detection input signal with an actual input signal and making a judgement under the position detecting control of an article storage system. CONSTITUTION:Position indexes 251 and 252 in different shapes arranged at a position index 25, and detectors 261, 262, and 263 for detecting them are provided oppositely, and only the detector 262 detects a position index with a detection level. Detector signals are supplied to a detection order storage and confirmation part 107 to check whether detection order is normal or not, and at a stopping position of a detection number, a current position controlling part 101 updates the current position to drive a moving machine by a movement control part 105 by comparison with the contents of a desired position storage part 104.</p> |
