<p>PROBLEM TO BE SOLVED: To provide a magnetic sensor-based apparatus for identifying coin-shaped detection objects which can by simplified configuration suppress the fluctuations of sensor characteristics due to external factors such as temperature variations.SOLUTION: An apparatus for identifying coin-shaped detection object 1 comprises: an excitation coil 8 and a detection coil 9; a bobbin 20 on which the excitation coil 8 is formed; a bobbin 21 on which the detection coil 10 is formed; a core body 11 on which the excitation coil 8 and the detection coil 9 are formed by way of the bobbin 20 and the bobbin 21; and a case body 3 in which the core body 11 is housed. A passage through which a detection body passes is formed within the apparatus for identifying coin-shaped detection object 1. In the case body 3 is formed a bobbin contact surface 3d with which the bobbins 20, 21 come into contact in the passing direction of the detection body. When the bobbins 20, 21 contact the bobbin contact surface 3d, the core body 11 on which the excitation coil 8 and detection coil 9 are formed is positioned in the passing direction of the detection body with respect to the case body 3.</p> |
