PURPOSE:To attain an upright image in the fixed position, even if a lens mechanism is rotated by providing a vertical deflection circuit and a horizontal deflection circuit in an image photographing tube, and making it possible to changeover the direction of scan to reverse up and down, left or right direction. CONSTITUTION:A vertical deflection circuit 14 and a horizontal deflection circuit 15 are set over in an image photographing tube, enabling to changeover the scanning direction reversely, up and down, left or right in accordance with the direction of electric current. In case that a lens mechanism 1 turns 90 deg. by a motor 2 set in the camera in watch motion, micro switch 6a or 6b is pushed by arm 5. Thus, a point of microswitch contacts 8 or 9 is closed, a magnet coil 13 is excited, points 11 and 12 in a relay 10 are switched over, and the direction of electric current running through a circuit 14 and a circuit 15 in the image photographing tube is inversed. As a result, even if the image photographed in the photographing surface of the image photographing tube is inverse, up and down, left or right, the upright image can be shown in display because the direction of scan can be changed over inversely.
