The light enters the light receiving element 37. For this reason, the amount of light received by the light receiving element 37 increases, and the detection accuracy of the light receiving element 37 is improved, and the detection range in the D direction is widened so that small-diameter regular coins C S1 deviating from the position of the light emitting element 36 can be detected. Become like Therefore, since it is not necessary to provide a plurality of pairs of light-emitting and light-receiving elements corresponding to the size of coins as in the related art, without increasing the number of light-emitting and light-receiving elements,
In addition, since the light emitting element 36 and the light receiving element 37 can be mounted on the same substrate 35, the number of the substrates 35 does not increase, and the assembling becomes easy. In addition, the distance between the focal points A and B can be changed by variously selecting the ratio between the long axis and the short axis, so that it is possible to cope with various coin diameters.

Without being limited thereto, for example, be formed in a planar shape is that no to say that that various design changes can be, short emission of a small diameter coin C S1 of the pair, the light receiving element It suffices if it can be detected by 36 and 37. Further, in the present embodiment, the reflecting mirror 38 as the reflecting member is fitted and fixed to the concave portion 3a of the cover 3 as a separate member from the cover 3, but the cover 3 has the same surface as the reflecting surface 38a of the reflecting mirror 38. The surface may be recessed in the cross-sectional shape and the surface may be subjected to a surface treatment such as nickel chrome plating or aluminum evaporation. In this case, the number of parts can be reduced and the operation of assembling the reflecting mirror 38 can be omitted. In the present embodiment, the example of the detected member is a coin, but the present invention is not limited to this, and it is a matter of course that any member that blocks light can be detected.

る。As described above, according to the present invention, light passes between the light emitting element and the light receiving element provided on one side and the reflecting member provided on the other side opposite to these two elements. A detection structure for detecting a member to be detected, wherein the cross-sectional shape of the reflection surface of the reflection member in the direction in which the light-emitting element and the light-receiving element are disposed is formed to be elliptical, and the light-emitting element and the light-receiving element are By being positioned at each of the two focal points of the ellipse, the range that can be detected by the pair of light emitting and light receiving elements can be expanded. Therefore, the number of light-emitting and light-receiving elements is not increased, and the light-emitting and light-receiving elements can be mounted on the same substrate. Therefore, the number of substrates can be reduced, and the number of components can be reduced. And easy assembling. In addition, the distance between the focal points A and B can be changed by variously selecting the ratio between the major axis and the minor axis, so that the detection range can be easily expanded.
