摘要

PROBLEM TO BE SOLVED: To provide a screw feeding device furnishing a reverse feeding mechanism which reduce the abrasion of a feeding claw engaged to a screw connecting band, and has a good durability of an engagement release member for connecting band reverse feeding. ;SOLUTION: A non-return claw 19 is engaged to an intermediate gear 15, so as to prohibit the rotation of a ratchet wheel 14 in the reverse feeding direction indiractly. By operating to press an engagement release button 18 for screw connecting band reverse feeding, the engagements of a ratchet arm 16 and the non-return claw 19 to the intermediate gear 15 are released at a time, so as to permit the rotation of the intermediate gear 15, and thereby, the rotation of the ratchet wheel 14 in the reverse feeding direction is permitted.;COPYRIGHT: (C)1998,JPO
