PURPOSE: To make the total height of a drive basically very low by vertically disposing an elevator cylinder to the traveling direction of an elevator plate and driving said cylinder and the elevator plate via a mechanical deflection gear mechanism.

CONSTITUTION: A piston rod of a cylinder 2 is integrally equipped with a horizontally projected material at its forwarding free end and is free of movement to a machine frame 1. When rotating an axis 12 of a gear 11 in gear with a rack 5, a deflection lever 15 is rocked and a roller 17 is moved and elevated simultaneously in a groove and a rail 18 is also elevated via a roller 17. The elevator rail 18 is coupled via an elevator plate 22 and a connection section 31. A heating plate 23 is mounted on the elevator plate 22 at certain intervals which results in obtaining a relatively wide elevating range by a piston rod movement along the cylinder 2 and ensuring the low total height.
