APPARATUS FOR CHECKING THE DISTANCE BETWEEN A SCANNING OR REPRODUCING HEAD AND A CYLINDER OF IMAGE SCANNING OR REPRODUCING EQUIPMENT

摘要

A system for preventing contact between an analyzing head and a transparent drum in a color scanner includes a drum reader for identifying which one of several transparent drums is installed on the scanner, and a head position reader for identifying the selected position of the analyzing head in a direction at right angles to a subscanning direction. The system further includes decision means for deciding whether the position of the analyzing head is suitable for the installed drum, and means for inhibiting movement of the analyzing head in the subscanning direction if the decision means determines that the position of the analyzing head is incompatible with the installed drum.
