Abstract
A detecting device includes a first electrode 42, a second electrode 44, and a conductive portion 14 mounted on a belt 12, for detecting a transverse movement of the belt 12. The electrodes 42 and 44 cooperate with the conductive portion 14 to form a contact-type switch, or mechanical switch. When the belt 12 moves from a first region 46 to a second region 48, the conductive portion 14 comes into contact with the electrodes 42 and 44 to close the switch. A control unit 50 detects an output from the switch. When the control unit 50 has detected a change of the output signal, it causes a correcting mechanism 24 to energize, thereby returning the belt to the first region.
