Can pass through the upper frame 10 and pull one of the operation cords 16 downward to pull the code gear 34e to drive the forward or reverse rotation of the scroll bar 34b. Adjustment of the slat 12 installation angle can be realized. Actually, the two operation cords 16 are converged, the middle portion of the operation cord 16 is consolidated, and a part of the cord is wound around the code gear 34e, so that both ends of the operation cord 16 are respectively hung on both sides of the code gear 34e. Thus, it is also possible to drive the rotation of the cord gear 34e in the forward / reverse direction by an external force, and thus the rotation of the scroll bar 34b in the forward / reverse direction.

  FIG. 9 shows a cordless shade, and a connecting universal joint 35 for connecting the central shaft 34 c is connected to a rotating rod 37. The rotary rod 37 is an alternative to the operation cord 16 for manually tilting the slat 12 in both directions. As described above, the shade adjustment mechanism 20 of this embodiment can provide two types of operation methods, manual and electric.

  Furthermore, the transmission structure 30 of the present embodiment further includes one position detection device 38 (see FIG. 2) so that the installation angle of the shade slat 12 after adjustment can be reliably confirmed. The position detection device 38 is installed in the fourth housing 28 and is supplied with power by the battery 40. The position detection device 38 identifies the rotation angle of the interlocking shaft 15 that is the actual angle of the shade slat 12. By stopping the interlocking shaft 15 at a specific angle, the shade slat 12 can be tilted to a predetermined inclination angle.

  Next, please refer to FIG. 10 and FIG. As another embodiment of the present invention, it is almost the same as the embodiment introduced earlier, the only difference is that the position detecting device 38 of this embodiment is installed in the fourth housing 28 as in the previous embodiment. Instead, it is installed in the first housing 22 instead. Similarly, the non-driving portion 15a of the interlocking shaft 15 is located at one end in the second housing 24, and the one end of the input shaft 30a is similarly inserted into the non-driving portion 15a, so that the worm gear 34a and the input shaft 30a are simultaneously The worm gear 34a and the input shaft 30a are connected so as to rotate. The position detection device 38 is connected to the other end of the interlocking shaft 15 corresponding to the input shaft 30a. Even with such a design, the actual installation angle of the shade slat 12 after adjustment can be similarly calculated.

  In summary, the rotation mechanism 34 is mainly installed in the second housing 24, and the fixed core 14 is mainly installed in the third housing 26, and the two housings are set as a general shade structure. The manual slat rotation angle adjustment mechanism main body becomes. On the other hand, in the case of the shade adjusting mechanism of the present invention, the set of the first casing 22 and the second casing 24 with the built-in drive motor 32, the battery 40, and the electric control without greatly changing the general shade structure. By simply providing a set of the fourth casing 28 and the third casing 26 with the built-in panel 36, the position detection device 38 is installed in the first casing 22 or the fourth casing 28, and the unit module is electrically driven. Remodeling can be realized if the unit is reborn, that is, if it is mounted inside the upper frame in a unit modularized manner.
