The interlocking member 308 is provided with an engaging portion 308a in which the rotating shaft 102 is fitted so as not to be relatively rotatable in the case 300-1, and the engaging portion 308a projects in the radial direction so as to be engaged with the clutch pin 305.

(Device operation)
The operation of the operation unit 30 configured as described above will be described. First, the operation of the clutch mechanism when the operation code 340 is pulled will be briefly described with reference to FIGS. 9 to 12. FIG. 11A is a partial front view showing a non-operated state of the operation code included in the operation unit according to the first embodiment, and FIG. 11B is a side view thereof. FIG. 12 (a) is a partial front view showing a state in which the operation code provided in the operation unit according to the first embodiment is pulled toward the front, and FIG. 12 (b) is a side view thereof.

When the screen 20 has already been lowered to the lowest position as shown in FIG. 11, the clutch pin 305 is not engaged with the engaging portion 308a of the interlocking member 308 as shown in FIG. ing. Here, when the operator starts to pull down the grip cord 342, the take-up cord 341 is unwound, the cord reel 301 rotates, and the mainspring spring 302 shrinks in diameter according to the rotation (see FIG. 7). Subsequently, the cord reel 301 begins to rotate integrally with the cam drive 307, the cam surface of the protrusion 307b comes into contact with the clutch pin 305, and the clutch pin 305 moves in the out-of-diameter direction to the engaging portion 308a of the interlocking member 308. Engage. At the time of the engagement, the protrusion 306b and the protrusion 307c are in contact with each other, and the state shown in FIG. 10 is obtained. As a result, the rotation of the cord reel 301 is transmitted to the rotation shaft 102 via the interlocking member 308, and these rotate integrally. The rotating drum 104 winds up the elevating cord 50 in response to the rotation of the rotating shaft 102, so that the screen 20 can be raised as shown in FIG.

If the grip cord 342 is pulled to some extent and then released, the winding cord 341 is wound by the mainspring 302 and the cord reel 301 rotates in the reverse direction. In response to this, the clutch pin 305 and the interlocking member Since the engagement with the 308 is released, the reverse rotation is not transmitted to the rotation shaft 102.

Since the opening 321 is formed, the stopper 343 can be tilted toward the front as shown in FIG. 13 (b). By further pulling it toward you in this tilted state, the stopper 343 can be derived not only from the lower surface side of the opening 321 but also from the front surface side as shown in FIGS. 12 (b) and 13 (c).

According to the operation unit 30 according to the present embodiment described above, in the accommodation space 320 accommodating the stopper 343, continuous openings 321 are formed on the front surface and the lower surface thereof. As a result, the stopper 343 can be derived from the front side as compared with the case where the opening is formed only on the lower surface, so that the grip cord 342 can be pulled down with an extremely high degree of freedom, and the operator can pull it down. The operability of the can be improved. For example, even if the operator moves to a position in front of and away from the operation unit 30 as shown in FIG. 12, the stopper 343 can be pulled out from the accommodation space 320 only by pulling down the grip cord 342 in a form of pulling it toward itself.

Therefore, the operation unit 30d can be attached to either end of the blind 1 in the left-right direction, and the grip cord 342 can be hung down either front or back, so that the operation position can be freely switched between front, back, left and right. Can be done.

<Sixth Embodiment>
In the first embodiment described above, it has been described that the take-up cord 341 is formed in the shape of a single string and the stopper 343 is formed in the shape of a hollow barrel, but the present invention is not limited to this. The take-up cord 341 may have a width so as to restrict the rotation of the stopper 343 at the time of take-up. Hereinafter, the blind operating device according to the sixth embodiment, in which the shape of the stopper is different, will be described with reference to FIGS. 21 to 22.

21 is a perspective view of the periphery of the operation unit according to the sixth embodiment, FIG. 21A shows a state when the operation code included in the operation unit is not operated, and FIG. 21B shows the operation code pulled toward the front.
