DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual operation device for manually operating a self-propelled carrier guided by a guide rail in an automatic operation mode when automatic operation becomes impossible. It is.

[0002]

2. Description of the Related Art The above-mentioned automatic operation transfer machine is operated automatically based on operation data set online or by remote operation.
If for some reason it stops during automatic driving,
It is necessary for an operator who has arrived at the stop site to directly operate the transporter manually to move the transport device to a maintenance inspection site. For this reason, means for manual operation are combined with this type of automatic operation carrier, but conventional means for this type of manual operation are incorporated into each automatic operation carrier. A manual operation panel and a manual operation panel connectable to an arbitrary automatic operation transfer machine are known.

[0003] Each of the operation panels is connected to the transporter by a curl cord or the like so that an operator can operate the transporter away from the transporter, but is guided by guide rails installed at a high place near the ceiling. However, it is not easy for an operator to take out the operation panel from the transporter or to connect the operator to the transporter. In addition, as described above, the incorporation of the operation panel for manual operation so as to be able to be pulled out for each of the automatic operation transporters leads to a significant increase in the cost of the entire equipment. Of course, it is also conceivable that the operation panel for manual operation is separated from the transporter, and the transmission of control signals between the operation panel and the control device of the transporter is performed using directional infrared rays or the like.
Since it is necessary to operate the operation panel while maintaining a state where the transmitting section of the operation panel is correctly directed to the receiving section of the transport apparatus that is a target of manual operation at a high place, not only the traveling operation of the transport apparatus but also the operation panel is required. It is not preferable as a manual operation operation method of this type of transporter which requires complicated and various types of manual operations including the operation of a load transfer device or the like provided in the transporter.
