发明名称 REMOVE CONTROLLER FOR LENS OF OPTICAL APPARATUS
摘要 PURPOSE:To perform remote control of the lens of an optical system by providing a driving system incorporated with a superconductive motor to the lens moving mechanism of an optical apparatus and a superconductive generator to a remote operation section acting as a command section and electrically connecting the generator and motor with each other by means of a power feeding section using a superconductive wire. CONSTITUTION:When a superconductive generator 1 is operated by one turn, the electric power produced by the generator 1 is fed to the superconductive motor 3 in the driving section of a lens moving mechanism through a superconductive wire 2 constituting a power feeding section. Because of the electric power supplied from the generator 1, the motor 3 is directly driven in the normal or opposite direction and the rotational force of the motor 1 actuates the lens moving mechanism. When the mechanism is actuated, remove control is performed on the lens of an optical system so as to make focusing, zooming, etc. Therefore, even though it is required to extend the length of the electric wire 2 constituting the power feeding section, the drive of the motor can be controlled directly by the electric power generated by the generator 1 only with high efficiency and remove control can be performed on the movement of the lens of the optical system without using any power source to an amplifier circuit section and amplifier.
