Abstract
A calibration determination device includes: a free roll that conveys the bonding member; a load detection device that detects a load applied to a bearing of the free roll; a tension adjustment device that winds the bonding member to increase a tension applied to the bonding member and unwinds the bonding member to reduce the tension applied to the bonding member so as to adjust the tension applied to the bonding member; and a calibration determination unit that determines whether calibration of the load detection device is necessary. The tension adjustment device unwinds the bonding member to cause the bonding member not to be subjected to the tension, and the calibration determination unit determines whether the calibration of the load detection device is necessary based on the load detected by the load detection device with the bonding member not being subjected to the tension.
