Zusammenfassung:	PURPOSE:To stop a mobile truck before its derailment, etc. by providing a recess surface detector to detect a recess part like a groove, etc. and output an alarm signal. CONSTITUTION:A mirror 8, a lens 9 and a camera 10 are provided to a mobile truck 4 containing wheels 6a-7b attached to the truck main body 5. Then the truck 4 is driven on a floor surface 2. The recess surface detectors 21 are set at the front of the front wheels 6 and at the back of the rear wheels 7 respectively. The detector 21 contains a rod 2 which can move up and down, a spring 25, a small wheel 26, a kicker 27 set at the upper end of the rod 23, a limit switch 28, etc. When the detector 21 is positioned above a groove, the rod 23 moves down and an alarm signal is delivered from the switch 28 via the kicker 27. A pilot lamp glows with the alarm signal. Thus an operator can change the driving direction or stop the truck 4 before its derailment, etc.
