- the fixing wire 52 of the moving side is gradually reduced in tension and the built-in spring (51b) is contracted.
- the fixing wire 52 is moved to the connected built-in spring (51b) side, when the fixed length is moved by the fixing weight 52a the fixing wire 52 is no longer interpolated into the fixing frame 51 fixed While the weight 52a is caught by the upper part of the fixing frame 51, the fixing wire 52 does not move by the rotation of the rotating shaft 30 (refer to B of FIG. 9).
- the elastic member 53 connects a pair of fixing wires 52 and is made of an elastic material, and as described above, the elastic member 53 can no longer move inside the fixing frame 51 by the fixing weight 52a, but the rotating frame ( If the 20 continues to move, the fixing wire 52 loses its elasticity. In this case, a problem arises that the fixing wire 52 on the side of the moving direction cannot pull and support the rotation frame 20.
- the fixing wire 52 when the fixing wire 52 is inserted into the fixing frame 51 side, the fixing wire 52 is introduced into the fixing frame 51 through an inlet hole (not shown) on the upper surface rather than being drawn into the open side.
- an alignment frame 54 having a wire through hole 54 a formed thereon is provided above the inlet hole, and a fixing wire 52 is provided inside the wire through hole 54 a to rotate the frame 20. Since it moves in accordance with the movement of the) and to minimize the movement of the fixing wire 52 can be rubbed with the inlet hole to prevent the wear of the fixing wire 52.
- engaging members 22a are respectively provided on both sides of the coupling part 22 so as to prevent the rotational frame 20 from rotating at a predetermined angle or more in the x-axis direction or in the moving direction.
- a pair of contact sensors 55 are provided on the upper surface of the center.
- the locking member 22a and the contact sensor 55 are automatically turned when the locking member 22a comes into contact with the contact sensor 55 when the rotation frame 20 is rotated by a predetermined angle or more (see FIG. 9C). As a result, the rotating shaft 30 can be stopped to prevent the rotation frame 20 from excessively rotating.
- the contact sensor 55 may be configured as a touch sensor or a contact switch for detecting contact with the locking member 22a.
- the rotation shaft 30 is directly connected to the motor M and rotates.
- the rotation force is sufficiently transmitted to a portion adjacent to the motor M, while the rotation force is increased as the distance from the motor M increases. There is a fear that not enough transmission affects the rotation of the panel and the rotation frame (10, 20).
- the first power transmission shaft 33 is further configured to be directly coupled to the outer circumferential surface of the rotation shaft 30, and the first power shaft 33 is a second power transmission directly connected to the motor M.
- the shaft 34 is connected through the chain 35, the second power transmission shaft 34 rotates to rotate the first power transmission shaft 33, thereby rotating the rotation shaft 30.
- the second power transmission shaft 34 having a smaller diameter may be connected to the first power transmission shaft 33 having a larger diameter through the chain 35 to rotate the rotation shaft 30 with less power.
- or 13 described only the main matter of this invention, and this invention is not limited to the structure of FIG. 1 thru
