2. Description of the Related Art It is difficult for an operator to directly lay pipes and cables such as ducts, racks, ladders, or underground laying pipes installed in the ceilings of stations or buildings. When a laying route extends over a long distance, a laying method using a nominal rope is adopted.For example, when laying a cable in an underground pipe, first use a rigid nominal rope. The cable is laid in the pipe by feeding the pipe from one end to the other end, connecting the cable to the end of the nominal rope that has passed through the pipe, and then pulling back the nominal rope.

Conventionally, as shown in FIG. 13, such a call rope has a rotatable storage body 50 for storing the call rope P in a wound state, and a delivery section 51 for feeding out the stored call rope P. It is stored in the call rope feeding device 200 having the above, is transported to the site, and is used by being fed from the sending section 51 while rotating the storage body 50 at the time of use.

However, in the conventional nominal rope feeding device, it is preferable that an operator is present near the device and the nominal rope can be fed out and fed into the laying path, but as shown in FIG. Duct D installed at a high place
Alternatively, or as shown in FIG. 15, when the worker S tries to work away from the apparatus 200 like the underground pipe C, the worker S holds the end of the call rope P and extends it. After that, even if you try to stop the feeding of the calling rope P,
The rotation of the storage body 50 does not stop due to the momentum when it is extended,
The call rope P is unwound more than necessary between the delivery section 51 and the worker S, and the call rope P is largely bent or twisted, and the work for sending the call rope P to the duct D or the underground pipe C is performed. There was a problem that it would be difficult.

Further, in the case of a nominal rope feeding device in which the nominal rope P is unwound and unreeled from the sending section 51 while rotating the container 50 by its elastic restoring force, the nominal rope P is the container. The force of being pushed out from the sending section 51 of the 50 always works, and the worker S
Only when the operator holds the end of the call rope P and moves away from the apparatus 200, the call rope P between the delivery unit 51 and the worker S is bent, and the call rope P is bent or twisted, and the duct D It becomes difficult to feed the nominal rope P into the underground pipe C or the underground pipe C, and the feeding state does not stop,
There was a problem that it interfered with other work and that the calling rope P could not be sent.

The present invention has been made in view of the above circumstances, and an object thereof is to prevent the call rope from being unwound from the sending section more than necessary even when the operator is at a remote position. The operator can perform the operation of unwinding the nominal rope such as unwinding, so that the work of laying various pipes and cables can be efficiently carried out.
Further, it is an object of the present invention to provide a nominal rope feeding device which is easy to handle.
