Abstract (en)

[origin: EP2671830A2] A stepping motor moves an upper-yarn catching member (30) by an amount corresponding to a specified number of pulses. A magnet sensor detects an origin position, which is a reference position, of the upper-yarn catching member (30). A number-of-pulse counting section obtains an actual measurement value, which is the number of pulses necessary for moving the upper-yarn catching member (30) from a target position to the origin position. A drive control section determines a standby position of the upper-yarn catching member (30) in view of the actual measurement number counted by the number-of-pulse counting section, a theoretical value, and the origin position.
