Abstract

Provided is a work machine or the like which can switch between a power supply state and a power supply cutoff state of an actual machine control device irrespective of switching on or off an actual machine switch. On switching an actual machine switch 81 from off to on, a first power supply route from an actual machine power source 80 to an actual machine control device 400 (from the actual machine switch 81 through a reference relay terminal 820 and a first relay terminal 821 of a five-pin relay 82 to a power source terminal 481) is formed. Consequently, a second power supply route from the actual machine power source 80 to the actual machine control device 400 (from a pair of relay terminals 840 and 842 of a four-pin relay 84 through a first diode 881 to the power source terminal 481) is formed. Then, the first power supply route is cut off, while the second power supply route not through the actual machine switch 81 is maintained.
