Claim 1
Independent Claim
228 words
A carrier for an IC package having rows of IC leads extended therefrom outwardly, which comprises: a carrier body having a receiving section defined therein for accommodating therein said IC package, a pair of latch levers disposed at the opposed sides of said receiving section and pivotally supported by the walls of said carrier body defining said receiving section as being rotatable about pivots between their respective locking positions and their respective unlocking positions, each of said pair of latch levers comprising a base portion at which the pivot is positioned, an operation portion for operating rotation of the latch lever, and a pair of fingers for supporting the corners of the rear surface of said IC package which are free from interference with said rows of IC leads and pinching said IC package in conjunction with the lower surface of said carrier body when the latch lever is in its locking position, said operation portion extending from said base portion upwardly of said carrier body and said pair of fingers extending from said base portion downwardly of said carrier body when the latch lever is in its unlocking position, and engaging means provided on both said carrier body and each of said pair of latch levers for maintaining said IC package in the pinched state when said pair of latch levers are in their respective locking positions.
Claim 2
Dependent Claim
