Abstract:
A first correction pattern and a second correction pattern are formed on an endless conveyor belt. The first correction pattern is located ahead of the second correction pattern on the conveyor belt with respect to the direction of movement of the conveyor belt. A sensor detects positional information of the correction patterns. A timing changing unit (controlling unit) changes a detection timing of the second correction pattern from a time point at which the sensor detects the second correction pattern.
