Title: Data taking-in control system for processing of face plate defect data
Inventor: ISHIWATA OSAMU
IPC: G01N21/88
Filed: 1987-03-19
Abstract: PURPOSE:To shorten the tact time for check of a face plate by stopping the working of a defect detecting part and the transfer of raw data after a time point when a data buffer is filled or edge data is satisfied with an edge data table. CONSTITUTION:When measurement of an entire area of a face plate is ended, a measurement end signal 5 is sent from a defect detecting signal processing part 7. Then an arithmetic start signal 6 is outputted to an arithmetic processing part 10 from a main control part 8 and the raw data are successively transferred from a buffer 9. Thus necessary arithmetic processing is carried out and the processed defect data is stored in a defect data table 11 together with out-of-range data stored in an edge data table 12 respectively. The satisfaction of the edge data is checked during the arithmetic processing. When the edge data is not satisfied, a waiting mode is set. While an edge satisfaction flag 16 is turned on and other tasks are processed when the edge data is satisfied. The routine is shifted to a data taking-in suppressing mode via a control part 8 while a buffer flag 15 or the flag 16 is kept turned on. Then a suppression signal 9 is sent to the part 7 so that the checking action and the transfer of data are discontinued.
