Patent ID: 7562765

Claim:
A panel carrying device which carries a panel, comprising: (a) a panel holding device that holds the panel; (b) a second link mechanism connected to the panel holding device; (c) a first link mechanism pivotally fitted to the second link mechanism; (d) a slide mechanism that moves the first link mechanism in a panel carrying direction, wherein the slide mechanism comprises i. a feed slide into which the first link mechanism is pivotally fitted; and ii. a first translatory actuator that drives the feed slide in the carrying direction of the panel; and (e) a swing mechanism that swings the second link mechanism, wherein the swing mechanism comprises i. a swinging link mechanism pivotally fitted to the first link mechanism and the second link mechanism; ii. a swing slide pivotally fitted to the swinging link mechanism; and iii. a second translatory actuator that drives the swing slide pivotally fitted to the swinging link mechanism in the carrying direction of the panel, wherein the first link mechanism is operable to swing back and forth in the carrying direction of the panel due to the slide mechanism and the second link mechanism is operable to swing back and forth in the carrying direction of the panel due to the first link mechanism, wherein the first link mechanism and the second link mechanism swing back and forth in the carrying direction of the panel by changing a relative distance between the feed slide and the swing side in the carrying direction of the panel, and wherein the first link mechanism and the second link mechanism move back and forth in the carrying direction of the panel by moving the feed slide and the swing slide in the carrying direction of the panel.
