Another purpose is to connect the transmitter and receiver antennas using a metal guide member, so that even weak radio waves can be transmitted over a longer distance, and are less susceptible to external radio interference. That's true. Another purpose is to make part of the control circuit cordless by using dry batteries as the power source for the transmitter, and to make it possible to select the control position 1 arbitrarily. be.

Furthermore, although a part of the control circuit is built into the moving device, since it is a wireless transmitter, signals can be extracted at any time even when the device is moving.

Effects The present invention controls the travel of a conveyance device that makes reciprocating motion or turning motion using a metal guide member such as a metal rail or metal wire as described above, and the metal guide member is connected to a radio transmitter and a radio transmitter. Since it is used as an antenna for a wireless receiver, it is possible to eliminate the need for an electric cord along the guide member in conveyance equipment such as roofing machines, elevators, track carriers, and ladder truck gondolas, making it possible to make the electric cord cordless. This has the effect of completely eliminating the problems of fatigue and wire breakage due to expansion and contraction, and the travel distance of the transport equipment can be freely set to be long or short, which has the effect of improving workability and running performance. Furthermore, since the antennas of the radio transmitter and radio receiver are connected by a metal guide member, the transmission distance can be extended even with weak radio waves, and the antenna is less susceptible to interference from outside. Furthermore, by using a dry battery or the like as a power source for the radio transmitter, a part of the control circuit can be made cordless, which has the effect that the control position can be arbitrarily selected.

Further, it is possible to obtain the effect that signals can be taken out even when a part of the control circuit is in motion.
