<p>PURPOSE:To prevent damage by the burning of a CRT screen by preparing a power control part which turns on and off the power supply of a CRT display part with the prescribed operations and is turned on with an instruction of a central processing part. CONSTITUTION:A remote/local power control part 7 turns on and off the power supply of a CRT display part 1 with the prescribed operations and is turned on with an instruction of a central processing part 5. Therefore an operator can optionally turns on and off the power supply of the part 1 with the prescribed operations. Thus the power supply is turned off in such a case where the screen of the part 1 has no change for a long period of time. As a result, the damage by burning can be avoided to the CRT screen.</p> |
