At the same time, the other end is connected to the interlocking slider of the winding side interlocking link mechanism, and both ends of the interlocking arm are interlocked with the winding side interlocking link mechanism, respectively. It is possible to adopt a configuration in which the slider and the interlocking slider of the feed-side interlocking link mechanism are connected.

The relationship between lock and unlock of 4 ′ is reversed, and clockwise rotation torque is transmitted to the take-up reel 48 through the clutch gear 63 of the one-way clutch 64 on the lock side, and the top tape 3 is wound.

When the take-up amount of the take-up reel 48 becomes full, the auxiliary reel 51 is removed from the reel boss portion 54 of the reel body 49 and removed, and the empty auxiliary reel 51 is attached again.

When the winding amount of the top tape 3 wound on the winding reel 48 increases, a difference occurs between the winding amount and the feeding amount in every half cycle. Take-up reel 4
There is a method in which a play portion is provided around a floating tension roller just before winding on the winding 8 and the play amount is adjusted to absorb the difference.

Driving force can be made constant, saving energy.

[0046]

As described above, according to the present invention, in the feeding and winding of the feed tape, the feeding and winding are performed in both the first half cycle and the second half cycle during one cycle of driving of the driving device. As a result, the speed can be doubled as compared with the conventional case in which the idle period is provided every half cycle.
