In this case, since the movable blades 9 are orthogonal to each other and the fixed blades 8 as well as the movable blades 9 are inclined at a predetermined angle .theta. = 30.degree. With respect to the horizontal plane, the harmful effect of obliquely cutting the empty tape is eliminated.

Further, the empty tape 7 which is drawn out so as to hang down with a predetermined curvature R moves together with the upward movement of the movable blade 9, and along the guide member 34 to both the cutting edges of the fixed blade 8 and the movable blade 9. On the other hand, since the tape surface of the empty tape 7 is guided so as to be orthogonal to each other, even a tape having a deep bottom (thickness) can be removed without any oblique cutting, and it is possible to eliminate a harmful effect such that the section is scattered outside the tape cutter device.

Further, the nozzle sucks the work from the carrier tape fed from the cassette 5 on the chip supply unit 1a at the mount head, and the tape is fed by a predetermined pitch P to feed the next work, and the empty amount. Since the tape 7 is synchronously cut by an amount equal to the feeding pitch P discharged from the cassette 5, even if the work remains in the empty tape, the chance of cutting the work is reduced, and the fixed blade and the movable blade are cut. The thing which can extend the life of is obtained.

In the above embodiment, the tape cutter device systematized with the component mounter has been described, but it goes without saying that the tape cutter device alone can be used.
