PROBLEM TO BE SOLVED: To provide a belt meandering controller capable of precisely and quickly converging the meandering of an endless belt, caused by disturbance in starting driving the belt, without causing damage to the belt. SOLUTION: In starting driving a belt, a control part computes the meandering speed of the belt in accordance with the position of a belt end 4a in a belt cross direction Z, detected by a belt position detecting sensor 7, at a timing when a home position detection part 5 detects a mark 3, to control the meandering speed of the belt to be in an allowable range. When the meandering speed is in an allowable range, the control part resets the position of the belt side end 4a in the belt cross direction Z, detected by a belt position detecting sensor 6, to be a new target position to control the meandering position of the belt so that the position of the belt side end 4a in the belt cross direction Z can be the new target position. |
