In present embodiment, described photoelectric sensor 12 is positioned at fixing relative position with described runner 14,, described photoelectric sensor 12 is all arranged at fixed position with described runner 14 and can not changes, and maintains the state that described photoelectric sensor 12 is relative with described runner 14 simultaneously.On described runner 14, having plural blade 142 arranges, described blade 142 is along with the described opening 122 of the relatively described photoelectric sensor 12 of described runner 14, described blade 142 also passes through in described opening 122 along with described runner 14 rotates, on the light path that described blade 142 conducts by described photoelectric sensor 12 light in described opening 122.The location that described blade 142 has according to described runner 14 arranges grouping and is arranged on described runner 14, it is that the location notch 144 with positioning action is set on the wheel shaft of described runner 14 that described location arranges, and described location notch 144 coordinates the common running of elasticity locating piece (not drawing in figure) that contiguous described runner 14 arranges to reach.Described locating piece is stuck in described location notch 144 when interior by elastic reaction, just can make described runner 14 to the position of described location notch 144 stop the rotation.In the time described runner 14 applied to larger torsion overcoming the elastic force of described locating piece, described runner 14 can be proceeded rotation running, in the time that rotation to described locating piece sticks into next described location notch 144, can make again described runner 14 stop once again, make described runner 14 produce the setting with location.In present embodiment, on the wheel shaft of described runner 14, with isogonism, described location notch 144 is set, and with the isogonism of 90 degree, four described location notchs 144 are set, described blade 142 is arranged on described runner 14 according to 144 points four groups of four described location notchs, and every group have two described blades 142, add up to eight described blades 142 and be arranged on described runner 14 (as shown in Figure 2).Eight described blades 142 are with different being spaced, described blade 142 is indicated with English alphabet a to p order with interval in Fig. 2 for ease of explanation, wherein English alphabet indicates blade a, c, e, g, i, k, m, o, indicates blade a and c, e and g, i and k, m and o and is respectively one group.English alphabet indicates interval width b, d, f, h, j, l, n, p, and indicating interval width b and d, f and h, j and l, n and p is the each group of interval width of
