Meanwhile, the program memory 41 divides the whole world on the basis of 15 degrees of longitude, and stores daily sunrise time and sunset time data for one year for each representative region. Therefore, when the curtain device user initially sets the current region and date (year / month / day) and time (hour / minute / second), and then plugs in the power cord 80, the sunrise of the day automatically automatically at any time. The curtain opens in time, and the curtain closes in time for sunset.

In detail, the daily sunrise time and sunset time data are different from region to region and are slightly different from day to day. Thus, the sunrise and sunset time data that are different from day to day and from region to region are stored, and the user sets the current date and time in the corresponding region. When the sunrise time and sunset time are determined by comparing the sunrise time and sunset time of the corresponding day of the corresponding area in the control unit 40 with the sunrise time or sunset time of the day stored in the program memory 41, At the time and sunset time, the operation of automatically opening or closing the curtain is repeated.

In other words, even if you do not set the time you want to open or close the curtain every time, at least at sunrise and sunset times, the curtain opens automatically and the light enters the room, or the curtain closes automatically so that the house is not visible from the outside. .
