PURPOSE:To provide a device for opening a windows easily in steps. CONSTITUTION:As window-opening starts from its state of complete closure, pulse signals from a limit switch 17 are counted with a counter 19 on every rotation of a detecting gear 16 that rotates in accordance with the movement of a geared cable 6. With a button 29 for 'half opening 1' and a button 31 for 'setting' pushed at a desired opening, values counted by the counter 19 are stored in a memory 21. With the button 29 for 'half opening 1' pushed afterward, a motor 11 starts and the counter 19 starts the counting. Then, the motor 11 stops when the values of this counting agree with the values stored in the memory 21, and a window 1 is partially opened to the desired opening. |
