<p>PROBLEM TO BE SOLVED: To provide a drawing device manufactured in such a manner that a recording drum used in the drawing device is subjected to the balance correction in accordance with the size of photosensitive material which is attached to the drum. SOLUTION: Annular grooves are cut on both end surfaces of the recording drum and every two balancing weights are disposed thereon. Normally, the balancing weights are pressed on an end surface of the grooves and tight fixed. At need, the weights are pressurized by adjusting pins which are disposed on the outer parts of the recording drum and, thereby, the fixation is released. In such a state, he balancing weights are moved relatively with respect to the recording drum and, thereby, the balancing of the drum is corrected.</p> |
