Abstract
A carrier tape is provided with a large number of accommodating recesses with each recess having a bottom surface, the top surface being open to accept an electronic part. Each accommodating recess is provided with resilient retainer arms formed together as a unit extending from the top surface of the recess, the resilient retainer arms permitting the electronic part to be inserted into the recess but preventing it from falling off.
Claims3
A carrier tape comprising:
- a resin tape having a plurality of part accommodating recesses arranged in series along the tape by means of a press,
- each recess having a bottom surface and open top, and a pair of opposing retainer arms projecting toward an inside of the recess, the retainer arms being formed integral with the resin tape and being flush with a top surface of the resin tape,
- said pair of opposing retainer arms being bent downward to permit an electronic part to be inserted into the recess, and said retainer arms recovering their flush with the surface position and extending over a portion of the electronic part to prevent the inserted part from falling off the tape.
A carrier tape comprising:
- a resin tape having a plurality of part accommodating recesses embossed by a press and arranged in series along the tape;
- each recess having a bottom surface and open top for admitting an electronic part, and
- a pair of opposing retainer arms projecting toward the inside of the recess, the retainer arms being formed integral with the resin tape and extending in a longitudinal direction of the resin tape,
- each of said retainer arms having a slant portion and a horizontal portion, said slant portion being inclined downwardly from a top surface of the resin tape toward an inside of said accommodating recess, and said horizontal portion being horizontally bent at a lower end of said slant portion;
- said pair of retainer arms having resiliency, so that said retainer arms are bent downwardly when a pair of clamping claws with the electronic part clamped therebetween are inserted into the accommodating recess, and said retainer arms contact both sides of the electronic part within said accommodating recess so as to hold the electronic part when said clamping claws are pulled upward from said accommodating recess.

A carrier tape comprising:
- a resin tape having a plurality of accommodating recesses formed by embossing the sheet-like resin tape by means of a press and arranged in series along the resin tape, each accommodating recess having a bottom surface and open top for admitting an electronic part;
- each accommodating recess having a pair of side walls having a slant surface, a vertical resilient portion, a swelling portion and a horizontal portion formed integrally with each other and formed simultaneously with forming said accommodating recess;
- said slant surface being positioned on the upper side of said side wall;
- said vertical resilient portion being formed by providing a slit in said side wall and by shaping a corresponding portion to be raised upwardly from said slant surface;
- said swelling portions extending from an upper end of said vertical resilient portion and projecting inside of said accommodating recess;
- said horizontal portion extending outward horizontally from an upper end of said swelling portion and being arranged on a level lower than a top surface of the resin tape;
- said vertical resilient portion having resiliency, so that said swelling portion is moved outwardly through contact of the electronic part when the electronic part is inserted from the upper side into the accommodating recess, and said swelling portion returning over the top surface of the electronic part to prevent the electronic part from falling off from said accommodating recess when the electronic part has been contained in the accommodating recess.
