<P>PROBLEM TO BE SOLVED: To detect the passing of a sheet material at two positions of a conveying passage by one sensor. <P>SOLUTION: A sheet material detecting device 100 has the first actuator 110, the second actuator 120, the third actuator 130, and a sensor (an optical sensor 140) switching on/off-states by the turning of the third actuator 130. In the sheet material detecting device 100, the third actuator 130 turns and switches one of the on/off-states of the sensor to the other by the engagement of the first actuator 110 and the third actuator 130 when the first actuator 110 turns by the sheet material (the sheet S), the third actuator 130 in the posture making the sensor the other of the on/off-states is turned by the engagement of the second actuator and the third actuator and the other of the on/off-states of the sensor is switched to the one by the second actuator 120 turning by the sheet material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
