Description of the invention (7) By the storage signal from the control unit, the rotary magnet 17 is actuated and the gate 14 is opened by the actuating pin 17a to open the coin discharge port 13b. The regular coins Cs in the coin storage chamber 13 are introduced into the coin storage and returned Rail 2 0 »At this time, the storage piece 2 5 a of the coin storage lever 25 opens the entrance of the coin storage rail 2 2, and the regular coin Cs is guided to the coin storage rail 2 2 and stored in the vault omitted from the circle. When detected by the detection unit 3 2 through the coin storage rail 2 2, the moving mechanism 16 is actuated and the movable frame 15 is moved slightly by 1 coin toward the inner surface of the first drawing surface to store the adjacent regular coins <: 3 coin storage ' The chamber 13 corresponds to the entrance position of the coin storage and return track 20. The second regular coin is stored. In this example, the light-emitting element 36 from the detection unit 30, 31, 32 emits light in the direction of arrow D, according to FIG. 4 The light path reflected by the reflecting surface 3 8 a of the reflecting mirror 3 8 will be described. Taking the ellipsoidal reflecting surface 3 8 a at any point P as a tangent line Sx— S2, if the line is P — H, and the two focal points of the ellipse are A and B, the relationship of ZAPH = ZBHP is usually established, ZS1PA = ZS2PB. That is, the incident angle Z S iP A of the light incident from the focal point A on the reflection surface 38 a at any point P and the reflection angle Z S2P B of the light reflected from the point P to the focal point B on the other side will generally be equal. Therefore, as shown in FIG. 3 (a), the light L reflected from the reflective surface 3 8 a that emits light from the light-emitting element 36 at the focal point A in the direction of arrow D, and the paper size applies to the Chinese National Standard (CNS) A4 specification ( 210X 297 mm) X Please read the notes on the back before filling out this page) -10-A 7 B7 Printed by the Consumer Labor Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs V. Description of Invention (8) All L2 shots are in focus B Light receiving element 3 7. Therefore, the light-receiving element 37 increases the light-receiving amount and the light-receiving element 37 improves the detection accuracy. At the same time, the D-direction detection range can also detect the small-diameter regular coin CS1 that is away from the position of the diffused light-emitting element 36. Therefore, it is not necessary to provide multiple pairs of light-emitting and light-receiving elements if corresponding to the size of coins, without increasing the number of light-emitting and light-receiving elements, and the light-emitting elements 36 and light-receiving elements 37 can be mounted on the same substrate 35. It does not increase the number of substrates 35, and the combination is easy. In addition, by selecting the ratio of the long axis to the short axis and changing the interval between the focal points A and B, it is possible to correspond to various coin diameters. Moreover, as shown in the third circle (b), the reflecting surface 3 8 a of the reflecting mirror 3 8 in the direction of arrow E forms a circular shape, and the light-emitting element 36 and the light-receiving element 37 are arranged at the center C of the perfect circle. The light-emitting element 36 emits light in the direction of E and reflects the light L3 and L4 on the reflection surface 3 8 a. All light is received by the light-receiving element 3 7. Therefore, the light-receiving element 3 7 increases the amount of light received, and the light-receiving element 3 7 increases the detection accuracy. . Furthermore, in this embodiment, although the reflection surface 3 8 a of the reflector 38 is formed into a perfect circle in the direction of the arrow E, it is not limited to this. For example, it can also be formed into a planar shape, and of course various design changes can be made The key is to use a pair of light-emitting and light-receiving elements 3 6 and 3 7 to check the small-diameter coin CS1. Also, although in this embodiment, the reflector 3 8 a of the so-called reflecting member is fitted with different members of the cover plate 3 It is fixed to the recessed portion 3 a of the cover plate 3, but it can also be recessed on the surface of the cover plate 3 with the same cross-sectional shape as the reflective surface 3 8a of the reflector 38 , Please read the precautions on the back before filling this page.) The size of the bound paper is applicable to the Chinese National Standard (CNS) A4 specification (210X 297mm) Fifth, the invention description (9) can reduce the number of parts and omit the combined work of the mirror 38. In addition, in the embodiment, a coin is taken as an example of a member to be detected, but it is not limited to this, and it is of course sufficient if light shielding can be detected. [Effects of the invention] If the invention is made in accordance with the above description, detection of the detected member between the light-emitting element and the light-receiving element arranged here and the reflection member arranged on the other side opposite to the two elements In the detection structure, the light-emitting element and the light-receiving element form an ellipsoid of the cross-sectional shape of the reflection surface of the reflecting member in the arrangement direction, and at the same time, the light-emitting element and the light-receiving element are respectively located at the two focal points of the ellipsoid to receive light Components expand detection range. Therefore, without increasing the number of light-emitting and light-receiving elements, the light-emitting and light-receiving elements can be mounted on the same substrate at the same time, and the number of substrates can be reduced, so the number of parts can be reduced and the assembly is easy. In addition, by selecting various ratios of long-axis and short-axis vehicles and changing the interval between focal points A and B, the detection range can be easily expanded. Furthermore, according to the present invention, the light-emitting element and the light-receiving element are formed by forming a perfect circle in the cross-sectional shape of the reflection surface of the reflection member in a direction perpendicular to the arrangement direction, and by positioning the light-emitting element and the light-receiving element at the center of the perfect circle, The light from the light-emitting element effectively makes the light-receiving element receive light, improving detection accuracy.
