Abstract

PURPOSE:To strengthen a device against bending and torsion, and also to improve a response quality of a moving part against operation of the operating part, by driving the moving part in an image pickup part, through fluid pressure from the side of an image receiving part. CONSTITUTION:In a cylindrical body 13 of an image pickup part 1, a piston 14 formed in one body with an image pickup lens 2 is provided, and between this piston 14 and a wall part 15 to which an image pickup plug 8 is connected, an oil pressure chamber 16 is formed. On the other hand, on an image receiving part 6, a cylinder 21 is provided, in which a piston 23 having an oil chamber 22 is stored. In this device, when an adjusting screw 25 is rotated, the piston 23 is pushed, and pressure of the oil pressure chamber 16 of the image pickup part 1 rises through an oil pressure pipe 17. As a result, the piston 14 is pushed, and the piston 14 and a lens 2 are stopped in a position where the pressure of the oil pressure chamber 16 and the spring force of a coil spring 20 are balanced.
