There is provided an inexpensive barycentric position measuring apparatus which measures a barycentric position accurately. The apparatus receives a load by a load receiving board, selects and switches a combination of a first sensor 5 and a second sensor 6, a combination of the second sensor 6 and a third sensor 7, a combination of the third sensor 7 and a fourth sensor 8 and a combination of the fourth sensor 8 and the first sensor 5 in turn by selection switching means, obtains output differences of all these combinations selected and switched in turn by the selection switching means 25 in output difference conversion means 14, stores in a memory 23 the output differences obtained in the output difference conversion means 14, determines in a barycentric position computation section 21 a first directional position (position Gy with respect to the y coordinate axis) and a second directional position (position Gx with respect to the x coordinate axis) based on comparisons of the output differences stored in the memory 23, and outputs the positions in output means 24. <IMAGE> |
