2. Description of the Related Art Generally, as a structure of an electric shutter for opening and closing a shutter curtain using an electric motor, as shown in FIG. 5, an output shaft of an electric motor 3 and a shutter curtain 5 are provided in a shutter case 1. There is known a structure in which the winding center of a winding basket 7 for winding is arranged in parallel, and the winding cage 7 is rotationally driven via a biaxial transmission means, for example, a chain transmission means 9.

However, as described above, the electric motor 3
In the case of a structure in which the take-up basket 7 and the take-up basket 7 are arranged in parallel, there is a problem that the depth width (storage space) of the shutter case 1 that houses them becomes large, and the shutter device does not fit well in the building.

Conventionally, a winding structure in which an electric motor and a winding cage are not arranged in parallel has been proposed as a solution to such a problem. In this winding structure, as shown in FIG. 6, a winding cage 7 is attached to an outer periphery of one end side of a support shaft 11 in a winding area of the shutter curtain 5 so as to be offset. And shutter curtain 5
The electric motor 3 and a transmission for transmitting the rotation of the electric motor 3 to the winding basket 7 are provided in the winding region of the outside and outside the winding cage 7 on the outer periphery on the other end side of the support shaft 11. Means 1
3 and a switch 17 including a receiver 15 and the like.

Only 5 is wound.

For this reason, since one end of the shutter curtain 5 wound around the winding basket 7 is wound in a state of being supported and fastened by the winding basket 7, the outer diameter of the shutter curtain 5 becomes small. The other end, which is wound only by the curtain 5, is loosely wound and the outer diameter becomes large, so that there is a difference in the amount of winding at both ends of the shutter curtain 5, and the winding balance may be deteriorated.

In order to solve the above-mentioned problems, the present invention provides a take-up structure for an electric shutter capable of improving the take-up balance at both ends of a shutter curtain while maintaining the size of the shutter case small. It is the purpose.
