本発明は、上記のような、従来のものの寿命を延ばそう
とするものである。In the conventional device as described above, the CT(i) life span is the shortest, and this is a major factor in determining the lifetime of the entire device. It is intended to extend lifespan.

Part of it is marked @ from timer control @#'c, CftT
When display data is input to 7 (time), the CRT display is set to high intensity, and after a predetermined period of time, the CRT display is set to low brightness.

The same thing as in figure E1, (7) is the input/output control section (3
) is controlled by the timer control section (7), and after the set time column a, the timer control section (8) starts counting the set time.
- A display level control unit that reduces the display level.
