<p>A device for moving a long article vertically, while always being held in a horizontal position, regardless of where and in what direction a force is exerted on the long article, and for use in, for example, a paper cutting machine has two actuation levers, each with two sloped end portions that are juxtaposed such that their slopes are opposed to each other. A bedplate is provide with guide members fixed on the two end portions of the bedplate for guiding the actuation levers to slide horizontally in parallel to each other. Drive members attached to the long article are mounted on the guide members and are associated with compression springs for biasing the drive members in an upward direction and to a predetermined height. The drive members are guided by the guide members to slide vertically and against the bias of the spring to abut the sloped end portions of the two actuation members such that the actuation levers are horizontally moved. This horizontal movement, and the interaction of the sloped end portions with the drive members causes the long article to be moved vertically while maintaining its horizontal orientation.</p> |
