VERTICAL DRIVE LOAD REDUCING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a vertical drive load reducing device which performs smooth vertical operations even with a small driving power source by keeping the balance of driven loads between upwards and downwards operations and also coping with the change of an installation angle of an input device. SOLUTION: When an image display input device is horizontally installed, the driven load of a vertical drive motor 10 increases at the time of lifting a displaying part 17 and in such a case, a reel rotary shaft 4 works together and is turned to the left by turning a reel rotational knob 5 to the left, a reel 3 rolls a wire rope 2 up and pulls a tensile spring 1 hung on a movable plate 8 and a rotational knob stopper is stopped at a prescribed place. Because the spring 1 generates tensile force in the direction that the plate 8 pushes a vertically movable shaft 9 upwards with a cam hole 8a, vertical drive load of the motor 10 can be reduced.
