PURPOSE:To make the operation in opening and closing directions of two push pieces the same and to correctly position by connecting two push pieces by two belts via the two pulleys arranged in opposite position to each other. CONSTITUTION:The push piece 11 operated by a rocking lever 5 is linked to a push piece 12 by a belt 31 via a pulley 21 and opened and closed by the operation of a tension spring 6. The push piece 11 is linked to the push piece 12 by a belt 32 via the pulley 22 arranged in the opposite direction to each other on a pulley 21. Both push pieces 11, 12 are regulated in the opening and closing both directions even at high speed operation time by this structure, so the positioning disorder is eliminated and positioning can be executed correct ly in a high speed operation as well. |
