A yarn pull-out device for pulling out a yarn from a winding part that winds the yarn to form a package comprising: a wound yarn catch and guide device including a move and catch part for sucking and catching a wound yarn that is a yarn in the winding part side by moving from a waiting position to a catching position in the winding part side; and a detection part for detecting the wound yarn caught by the wound yarn catch and guide device; the move and catch part that approaches the detection part by moving from the waiting position to the catching position, the detection part that detects the presence or absence of the wound yarn inside the move and catch part moved to the catching position, characterized in that the detection part includes: a light emitting part for emitting light to a detecting position within the move and catch part; and a light receiving part for receiving light that is emitted by the light emitting part and reflected at the detecting position, or that is emitted by the light emitting part and passed through the detecting position, a light passing part at which light emitted by the light emitting part is passed through is provided in the move and catch part. a wound yarn catch and guide device including a move and catch part for sucking and catching a wound yarn that is a yarn in the winding part side by moving from a waiting position to a catching position in the winding part side; and a detection part for detecting the wound yarn caught by the wound yarn catch and guide device; the move and catch part that approaches the detection part by moving from the waiting position to the catching position, the detection part that detects the presence or absence of the wound yarn inside the move and catch part moved to the catching position, characterized in that the detection part includes: a light emitting part for emitting light to a detecting position within the move and catch part; and a light receiving part for receiving light that is emitted by the light emitting part and reflected at the detecting position, or that is emitted by the light emitting part and passed through the detecting position, the move and catch part that approaches the detection part by moving from the waiting position to the catching position, the detection part that detects the presence or absence of the wound yarn inside the move and catch part moved to the catching position, characterized in that the detection part includes: a light emitting part for emitting light to a detecting position within the move and catch part; and a light receiving part for receiving light that is emitted by the light emitting part and reflected at the detecting position, or that is emitted by the light emitting part and passed through the detecting position, a light emitting part for emitting light to a detecting position within the move and catch part; and a light receiving part for receiving light that is emitted by the light emitting part and reflected at the detecting position, or that is emitted by the light emitting part and passed through the detecting position, a light passing part at which light emitted by the light emitting part is passed through is provided in the move and catch part.
