  Furthermore, the support mode of the reflection plate is also suspended by using a pair of front and rear tilt strings and a pair of left and right tilt strings as in the above-described embodiment, with a plurality of reflectors spaced vertically. Reflector support mechanism that supports the middle of each side of the reflector on a plurality of tilting support rods that stand substantially vertically from the lower frame of the window, for example, and a plurality of tilting support rods relative to each other in the vertical direction. Front / rear tilt angle changing mechanism for changing the tilt angle of the reflector in the front / rear direction by moving, and a left / right tilt angle for changing the tilt angle of the reflector in the left / right direction by relatively moving the plurality of tilt support bars in the vertical direction A change mechanism may be employed.

  In addition, the reflector is not limited to a mode in which the tilt direction of the reflector is changed by automatically tracking the direction of the sun by the control device as described above, but only by manual operation with respect to the forward / backward tilt angle changing mechanism and the left / right tilt angle changing mechanism. A mode in which sunlight is guided to a diffusing plate or the like provided on the ceiling by changing the tilt angle may be adopted. Of course, instead of the control device using the microcomputer system according to the above-described embodiment, a control device using a general-purpose information processing device represented by a personal computer may be adopted. Furthermore, you may make it add the data which show the inclination of a window to the positional information in embodiment mentioned above. In this case, the window position input numeric keypad also accepts an input of the window inclination indicated as an angle in which the normal line of the window forms the horizontal direction, and the window position signal output by the window direction input receiving means indicates the window inclination. Also includes data to show. Further, the position information database stores the correspondence between the date and time corresponding to the typical window inclination, the front-rear direction tilt angle and the left-right direction tilt angle of the reflector. The position of the window is determined by using, for example, a keyboard, in addition to specifying the longitude and latitude from the correspondence between the date and time, the front-rear direction tilt angle and the left-right direction tilt angle of the reflector as described above. The input means accepts the input of the city name including the location of the building with the window, and stores the correspondence between the city name and the longitude and latitude in the position correspondence storage means formed using a predetermined area of the storage device. Another possible mode is one in which the position specifying means searches and specifies the longitude and latitude of the window corresponding to the city name received by the position input means from the stored contents of the position correspondence storage means. In addition, the position input means configured by using a keyboard or the like replaces the mode in which the city name is input, and the position input means configured by using a numeric keypad or the like receives the input of the longitude and latitude of the window. Is also possible.

  In addition, the reflecting plate of the present invention is not limited to a flat plate, and various modifications can be made without departing from the spirit of the present invention, such as using a concave mirror.
