PURPOSE:To improve efficiency of supplying electronic parts by unwinding a tape where electronic parts are held at equal spaces from a tape reel to feed out the parts by designated pitches, and simultaneously separating the lower skin of the tape to be rolled round. CONSTITUTION:There is provided a tape comprising an upper skin 39 having a lot of guide holes 41 on both sides and large opening holes formed at the center thereof by equal pitches, and a lower skin 38, wherein an electronic part 40 is placed corresponding to the large opening hole, and retained by the adhesive force of the lower film 38 adhering to the lower surface of the upper film 39 through the above opening hole. In case of supplying the electronic parts 40, a pivotal lever 4 is moved centering around a flat shaft 5 by the up-and-down motion of a pin 3, and sprockets 6a, 6b are turned by designated angles through a ratchet mechanism to feed the tape pitch by pitch. Simultaneously with the above operation, a pivotal lever 34 is turned around a supporting point P, so that the lower skin 38 is pushed down through a roller 35 to separate from the upper skin 39. |
