  • Apparatus and method for automatically detecting presence of a scanned document
    Patent number: 6008501
    Abstract: The present invention discloses a scanned document auto-detecting apparatus for detecting the presence of a scanned document without additional control circuit. Based on the decision result, a scanning procedure starts to degrade cost by removing the additional control circuit, and furthermore, the scanned document auto-detecting apparatus can prevent users from running the scanning procedure wastefully when there is no scanned document. The scanned document auto-detecting apparatus sets a specific pattern at inner side of the cover. This specific pattern is first scanned before the scanning procedure starts as to decide the presence of the scanned document.
