It is a block diagram which shows a height measuring device. As shown in the figure, the trolley 1 includes wheels 2 and a hand pusher 3. The trolley 1 is provided with a pulse encoder 4, a level gauge 5, a potentiometer 6, an A / D converter 7, a computer 8, a measurement start switch 9 and a display unit 10.

The number of pulses P that have been input since the time when was input is counted, and the traveling distance of the trolley 1 is calculated from this count value. That is, the circumference of the wheel 2 is known in advance,
Further, since the rotation amount of the wheel 2 is known from the pulse count value, the traveling distance of the trolley 1 can be calculated.

By traveling on the top, the inclination angle and the height position can be continuously detected. In this case, since the data of the pulse encoder 4 and the level meter 5 are not directly read by a person but sent to the computer 8, there is no erroneous reading and the measurement accuracy is high. Moreover, just pushing this device allows continuous measurement in a short time.
