For this reason, even if the box 2 is returned to the original position after the box 2 is once tilted or overturned, if the operator observes the transparent portion 20 of the detection device 30 as shown in FIG. Since it is not possible to confirm the presence of the disk 11 from the reference numeral 20, the fact that the box 2 has once fallen can be clearly confirmed, and if the display screen of the display device 53 is viewed, it is displayed there. Since the time at which the measurement of the current time was stopped (for example, 2003.05.12.14:13) is displayed, it is possible to clearly recognize the time at which the box 2 fell or the elapsed time since the start of the measurement. it can.
[0055]
【The invention's effect】
As described above, according to the present invention, the time measurement is stopped by the disk that rolls in accordance with the inclination of the object, and the timer means for displaying the time at which the measurement is stopped is provided. It is possible to clearly recognize when an object such as a box has tilted or overturned, thereby easily identifying the cause of a failure of an article such as a precision instrument housed inside the object and causing a failure during transportation. Immediate measures to improve the factors can be taken.
[0056]
Further, since the time at which the tilt or the fall is displayed by the timer means, it is possible to eliminate the mischief that hides the fact that the disc body has been returned to the original position and the fact that the tilt or the fall has occurred.
