Patent abstract
A substrate detection system is disclosed to include a conveyer that delivers the substrates, a sensor that detects the length of each substrate being delivered by the conveyer over the top side of the sensor, and a processor that compares the detection length value of each substrate detected by the sensor with a predetermined length value stored therein so as to immediately stops the conveyer when the detection length value of one substrate is unequal to the predetermined length value. In an alternate form, the time value in which each substrate passed over the sensor is used as a parameter for judgment.
