PROBLEM TO BE SOLVED: To realize the miniaturized device and the simplified operation by controlling each operation of photographing or communication selected by operation changeover based on a result of detection of a turning angle of a rotary shaft that can be rotated and translated. SOLUTION: When a lever push button switch 106 is set to a photographing mode, a video image of opposite party 103a and its own image 103b are displayed on a liquid crystal display device 103. When a lever push button switch 106 is turned upward (downward), a photographing lens 101 of its own is zoomed toward a wide angle (telescopic) position to obtain a wide angle (telescopic) image 103b. When the lever push button switch 106 is detached, zooming of the photographing lens 101 is stopped. When the lever push button switch 106 is pressed, an object of operation changes to a portable video telephone set of the opposite party. When the lever push button switch 106 is turned upward (downward) a photographing lens 101 of the opposite party is zoomed toward a wide angle (telescopic) position to obtain a wide angle (telescopic) video image 103a. |
