<p>PURPOSE:To simplify the construction of a storage device and allow articles to be selectively extracted even if they are stored at random by storing the storage article information and the article presence signals of storage sections in an article storage register section and controlling them in a reproduction video cassette storage device. CONSTITUTION:The presence of an article in a cassette storage section 11 is detected by a sensor 13 and is fed to a cassette storage register section 15 via a waveform shaping circuit 14. This register section 15 detects a change of the presence of a cassette in the storage section 11. On the other hand, the information of the cassette to be stored in the storage section 11 is displayed on a cassette display section 17 via a cassette display control circuit 16. An operator feeds the cassette to the cassette storage section 11 based on this display 17. Thereby, the register section 15 detects a change of the cassette state from non- exisence to presence in the storage section 11 and registers the cassette information and the change of the cassette in the storage section 11. According to this constitution, cassettes can be correctly stored even if they are inserted at random.</p> |
