<p>PURPOSE:To quickly change the arranging pitch of platy bodies by simultaneously moving platy body holding members on both sides by using a driving shaft composed of a first shaft equipped with a right-hand thread and second shaft equipped with a left-hand thread, with the first and second shafts being coaxially coupled with each other. CONSTITUTION:When a drive motor 62 starts to rotate, a driving shaft 4 is rotated through a driving belt 64 and pulley 61. When the shaft rotates clockwise, a first driving arm 51 engaged with a first shaft 41 equipped with a right- hand thread moves rightward and a second driving arm 52 engaged with a second shaft 42 equipped with a left-hand thread moves leftward. As a result, the arranging pitch of platy body holding members 3 and 3 becomes longer. When the shaft 4 rotates counterclockwise, on the contrary, the pitch becomes shorter. Since a link mechanism 7 controls the arranging intervals of the members 3 and 3 to regular intervals, the arranging pitch of the members 3 and 3 can be continuously changed by rotating the shaft 4 clockwise or counterclockwise. In addition, the arranging pitch can be strictly controlled by the rotation of the shaft 4.</p> |
