Pull out to the working side (arrow i). In this movement, the piles of the tape scraps 15 * that have been deposited in a convex shape immediately below the tape discharge duct 27 may collapse due to the movement of the tape discharge box 29 (arrow j).

  At this time, since the front end portion 29a of the tape discharge box 29 protrudes from the lower end portion of the tape discharge duct 27 toward the apparatus main body at the initial position, the deposition position of the convex accumulation portion is shown in FIG. It is inside the protrusion dimension D shown in FIG. Therefore, even when the accumulation portion collapses, the tape scrap 15 * does not spill outside the tip portion 29a and fall. Therefore, there is no problem that has occurred in the prior art, that is, the problem that the pile of tape debris deposited directly under the tape discharge duct collapses and falls outside the tape discharge box does not occur. There is no need to clean and remove tape scraps spilled on.

  The component supply device and the component mounting device according to the present invention have an effect that tape scrap recovery can be efficiently performed by effectively utilizing the volume of the tape discharge box, and the electronic component is supplied from the tape feeder that pitches the carrier tape. This is useful in the field of taking out and mounting on a substrate.
