摘要:
A numeric controller including a display with a built-in power supply and a power supply-dependent type display outside the numeric controller. Power supply synchronization means is provided which turns ON/OFF a power supply (4) of a power source built-in type display B (3) in response to ON/OFF of the power supply (2) of a numeric controller main body (1). When the power supply of the numeric controller main body (1) is turned ON/OFF by this power supply synchronization means (9), the power supply (4) of the display B (3) is turned ON/OFF synchronously and a power supply to be supplied (6) of the power supply-dependent type display A (5) is turned ON/OFF, as well. Accordingly, a clear circuit (10) is operated by using a button (11) of the display A (5).
