<P>PROBLEM TO BE SOLVED: To provide a blind which facilitates the operation of an operation dial while keeping the size of an operation case small. <P>SOLUTION: An operation case 28 for accommodating an operation unit 14 is provided at one end of a head box 10. The operation unit 14 has an external gear 30 connected to one end of a rotating shaft 12 so as to rotate integrally with the shaft 12, and an operation dial 32 rotatably supported at a support position offset from a shaft center of the rotating shaft 12. Internal teeth 32a are formed on the inner periphery of the operation dial 32. The operation dial 32 can transmit rotation of the same direction as the operation dial 32 to the external gear 30 through the internal teeth 32a. A part of the operation dial 32 is exposed from the front or rear face of the operation case 28, which enables rotational operation from the outside. <P>COPYRIGHT: (C)2012,JPO&INPIT |
