<p>An image-forming machine comprising a supporting structure (6) comprised of a lower supporting frame (2) and an upper supporting frame (4) mounted on the lower supporting frame so as to be free to pivot between an open position and a closed position, locking means (40) for releasably locking the upper supporting frame (4) at its closed position, and a cover member (62) mounted on the supporting structure (6) so as to be openable and closable. The locking means (40) has an engaging member (42) mounted movably between a locking position and a releasing position. The cover member (62) can be maintained in its closed state only when the upper supporting frame (4) is at its closed position and the engaging member (42) is at its locking position.</p> |
