Abstract: PURPOSE:To obtain a miniaturized high accuracy driving device driving a 2nd group lens frame by simple constitution by driving said lens frame by variable power in response to the difference between a barrel frame and a 1st group lens frame. CONSTITUTION:The 1st group frame 6 supporting a 1st lens group 5 is supported movably in the direction of an optical axis in the barrel frame 4 movable along guide axes 24-26 fixed to a fixed frame 1. The 2nd group frame 7a supporting a 2nd lens group 7 is supported in a 2nd group frame cam 9 driven by the 1st group frame 6 so that the frame 7a can advance and retreat. When the barrel frame 4 is advanced and retreated by a motor 11, the 1st group frame 6 is advanced and retreated by driving screws 21-24. The 2nd group frame 7a is advanced and retreated in response to the difference between the moving amount of the 1st group frame 6 and that of the barrel frame 4 through the cam 9. As a result, the miniaturized, high accuracy driving device capable of driving the 2nd group frame by its simple expedient can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide an electron beam device effectively preventing penetration of ions into an electron gun. SOLUTION: A controller 26 computes a velocity ve of an electron so as to find a current I to be fed to a coil 22 and a voltage V to be impressed between parallel flat electrodes 24 so that a ratio between an electric field strength E and a magnetic flux density B becomes the electron velocity ve, and then, gives commands to respective circuits so that a current supplying circuit 23 feeds current of the found value to the coil 21 and a voltage supplying circuit 25 impresses voltage of the found value between the parallel flat electrodes 24. A superimposing filed between an electric field and a magnetic field is formed in a space crossing a clearance of an iron core 21 and a space between the parallel flat electrodes 24, and electromagnetic force based on the superimposing field works only on an ion placed in an electron path so as to eject the ion from the electron beam path.  To an electron directed from an electron gun 1 to a target 9, electric force and magnetic force are canceled by each other, and consequently, no electromagnetic force is applied apparently.
