Abstract
A monitor camera transporting apparatus (10) which comprises rails (12) laid along a transportation path of a monitor camera (11), a carriage (21) having the monitor camera mounted thereon and movable along the rails, and transporting means (31) for moving the carriage by means of compressed air. The transporting means includes a pipe (32) provided parallel to the rails and having a slit (32a) formed in its lower part along a full length of the pipe, an internal moving body (34) movable within the pipe by means of compressed air introduced into the pipe, a connecting plate (33) connected at its one end to the internal moving body and externally projected at the other end through the slit to be connected with the carriage, a sealing wire (36) disposed within the pipe along the full length of the pipe to close the slit, and a wire retracting part (37k) formed in the internal moving body or connecting plate for retracting inwardly of the pipe the sealing wire located at the connecting plate. Thereby, even at such dangerous place where no persons are allowed to enter and no electric motors can be used, the monitor camera can be transported efficiently, safely and reliably even to such …
