<P>PROBLEM TO BE SOLVED: To improve reliability of detecting a foreign matter in detecting a token passing through a path while simplifying the arrangement of optical equipment. <P>SOLUTION: A token detection unit 210 includes a light emitting portion 216 and a light receiving portion 220 which are provided on a body 212. The detection unit 210 reflects light emitted from the light emitting portion 216 on a reflecting surface 218 in front of the light emitting portion 216, and irradiates a token M passing through a main path 203 from a direction obliquely crossing the token surface. The light receiving portion 220 is situated opposite to the reflecting surface 218 across the token M. The light receiving portion 220 receives light (reflected light) from a direction obliquely crossing the token M passing through the main path 203, and outputs a predetermined light receiving signal according to the light quantity of the received light. <P>COPYRIGHT: (C)2012,JPO&INPIT |
