If foot is of a size of L.At this, the X-Y coordinate is defined as: with above-mentioned initial point O is initial point, is that the positive direction of X coordinate, former direction are the positive direction of Y coordinate with the right of overlooking observation.At this moment, the Y coordinate figure of heel location division 51 is-D/2 that the Y coordinate figure of the center Go of foot is-D/2+L/2.In addition, by medial surface location division 53a or lateral surface location division 53b being formed on the symmetrical position of mounting plate 1, thereby the X coordinate figure of the center Go of foot is 0.And the coordinate of the position of centre of gravity of calculating with weight sensor 2 and calculation mechanism 3 is [X, Y].
Relative therewith, position of centre of gravity by indication mechanism 4 demonstrations, owing to be to be the coordinate system (with it as X '-Y ' coordinate) of initial point with original position of centre of gravity (being the center Go of foot), so as can be seen, when this coordinate be [X ', Y '] time, draw from the coordinate of the center Go of above-mentioned foot:
X′＝X
Y′＝Y+D/2×(1-L/D)
Also can on the Y coordinate, add correction value Δ y=D/2 * (1-L/D) revise.
For example, as shown in Figure 2, be under the situation of D at foot size L,
X′＝X
Y′＝Y+D/2×(1-D/D)
＝Y
As a result, need not revise.
In addition, for example, as shown in Figure 3, be under the situation of D/2 at foot size L,
X′＝X
Y′＝Y+D/2×(1-D/2/D)
＝Y+D/4
Need to revise D/4.
In addition, shown in the embodiment of Fig. 7 (a), under situation about positioning, because the Y coordinate figure of tiptoe location division 52 is D/2, so the Y coordinate figure of the center Go of foot is D/2-L/2 with tiptoe location division 52.Thus, with similarly above-mentioned, as can be seen
X′＝X
Y′＝Y-D/2×(1-L/D)
Also can on the Y coordinate, add correction value Δ y=-D/2 * (1-L/D) revise.
Then, based on Fig. 8 other embodiments are described.In the embodiment of Fig. 1～shown in Figure 6, heel location division 51 is configured in the position of the weight sensor 2 that is provided with rear side, on the Y coordinate, add correction value Δ y=D/2 * (1-L/D) revise.
Relative therewith, in embodiment shown in Figure 8, heel location division 51 is configured in the position of forwards staggering d from the position of the weight sensor 2 that is provided with rear side.Therefore, Δ y=D/2 * (1-L/D)-and d, be modified to:
X′＝X
Y′＝Y+D/2×(1-L/D)-d。
In addition, though diagram not is configured in tiptoe location division 51 under the situation of position of the d that rearward staggers from the position of the weight sensor 2 that is provided with the front side, Δ y=-D/2 * (1-L/D)+d is modified to:
X′＝X
Y′＝Y-D/2×(1-L/D)+d。
