Abstract

PURPOSE: To improve endurance and stabilize door opening and closing by linking a roller of the sliding body at the lower portion of a door to a spiral groove formed on a rotation shaft and opening or closing the door by the rotation of the rotation shaft thereby prohibiting no occurrence of dust from the rotating portions. CONSTITUTION: A door 18 supported in a movable manner through guide rollers at the upper and lower guide rails 14, 16, and a rotation shaft 20 with a spiral groove 28 formed on the peripheral surface are provided, and a slide block 34 having a roller 32 linking to the spiral groove 28 and sliding in the shaft direction by the rotation of the rotation shaft 20 is attached to a lower portion of the door 18. And the rotation shaft 20 is rotated, the roller 32 is rotated on the spiral groove 28 and, by its rotating force, the slide block 34 moves in the direction corresponding to the rotating direction of the rotating shaft 20 and the door 18 can be opened or closed. Also, a plurality of spiral grooves and rollers for the rotation shaft 20 can be provided or a plurality of rollers can be linked to a single spiral groove in the configuration.
