PURPOSE:To esnure the free designation of the sampling pitch ih the XY direction and independently, by varying freely the sampling pitch number in the XY direction and individually. CONSTITUTION:The pitch designated out of the software and via data sampling pitch command line 11 is stored in sample pitch register 1. The contents of register 1 is loaded to strobe pulse counter/comparator 2 via the index pulse supplied from signal line 6, and then compared with the count value of the strobe pulse of the drum. And if the coincidence is obtained, the coincidence signal is transmitted to strobe pulse inhibition circuit 3. Thus circuit 3 applies the inhibition to the strobe pulse and based on the coincidence signal. Here if no strobe pulse is delivered, the picture image data is never latched for that time. With this strobe pulse, the picture data of the drum is latched to data register group 4, and the contents of the data is transferred to the picture memory. |
