Vehicle condition detection device and vehicle speed measurement device

摘要

PROBLEM TO BE SOLVED: To provide a vehicle state detecting device and a vehicle speed measuring device which can be attached to a vehicle in an appropriate orientation even if it is temporarily installed. SOLUTION: A speed measuring device 1 is a case 50 having a lid surface that can be opened and closed, and the bottom surface of the case 50 facing the lid surface is fixed to a flat surface covered with a vehicle license plate NP. It has a mounting device that is fixed to the device 12. A camera 22 and two laser output units 24 and 25 are installed inside the case 50 partitioned between the lid surface and the bottom surface. The two laser output units 24 and 25 can irradiate the laser beam downward through the opening 57 provided in the lower surface 51D of the case 50, and the camera 22 passes through the opening 56 provided in the lower surface 51D of the case 50. It is possible to take an image of the laser beam emitted downward. [Selection diagram] Fig. 1
