HOME CONTROLLER

摘要

PURPOSE:To improve the operability and to save the energy by turning on a power supply for a CRT display serving as a display part and also actuating a scanning operation of a key serving as an input means only when a main controller is operated. CONSTITUTION:If a human body is positioned within a range of detection at the front of an operation panel while a main controller 1 is operated, a sensor part 10 detects the human body. Then a detection control part 11 delivers a detection signal to a CPU7. The CPU7 transmits a command to turn on the power supply of a display part 13 and the data on the prescribed display contents stored in a memory 8 to a display control part 14. In addition, a key matrix 16 is scanned by an input control part 17 to start a key input.
