PURPOSE:To deal with an occasion when data are difficult to observe by allowing the selective switching between whether to display data by overlapping an image or to display data by cutting part of the image by means of a data photographing switch switching whether to photograph data or not. CONSTITUTION:A control unit checks whether a scanning start switch is turned on or not; if the judgement is NO, whether a data photographing switch is ON or OFF is checked, in case of ON a CRT screen is set to a normal mode (full screen), and in case of OFF the CRT screen is set to a partially-cut mode; then the operation is returned to (x) and waits for the scan start switch to be turned on. If the judgement of step (a) becomes YES, the control unit starts the scanning to display the sample image on the CRT, and the photographing proceeds. When the sample image is photographed with data overlapped on it, this switch can be left ON at steps (a), (b). When data are photographed with part of the image cut off, this switch must be kept ON until step (f) is reached. |
