PURPOSE:To correct the inclination of an image due to the swing of a direction changer to a positive situation image by a simple structure by installing a positive situation image correcting device between the direction changer and an image pick-up device. CONSTITUTION:The incident light l1 projected from an image pick-up object is collided with a reflex mirror 1 through the first lens 2, and the reflected light l2 is projected into a trapezoidal prism 20 through the second lens 3, and the incident light l3 is refracted and reflected by the trapezoidal prism 20 and projected into the first image pick-up device 19. When a remote control switch 24 is turned on and the second servomotor 22 is driven, the trapezoidal prism 20 revolves, and the first direction changer 25 is revolved twice at the revolution angle in the same direction to the revolution of the trapezoidal prism 20 by an H gear 18 or A gear 8. Therefore, the inclination of the image due to the swing of the first direction changer 25 can be corrected always to a positive situation image by the trapezoidal prism 20. |
