Abstract
Abstract An IC package carrier comprises an IC package support plate having a square IC package accommodation section at the center thereof; an IC package press plate having at one end thereof a handle section for causing the IC package press plate to rise from and lie down on the upper surface of the IC package support plate, at the center thereof a square press section for pressing a square IC package, at the other end thereof a hinge mechanism for coupling the IC package press plate to the IC package support plate and serving as hinges about which the IC package press plate is rotated, and two pairs of arms, one pair for connecting the handle section to the square press section and being superposed on one pair of adjacent corners of the IC package accommodated within the square IC package accommodation section of the IC package support plate and the other pair for connecting the square press section to the hinge mechanism and being superposed on the other pair of adjacent corners of the IC package; and closure retaining means provided for detachably retaining the IC package press plate in a state of having lain down on the upper surface of the IC package support plate.

Claim 1
Independent Claim
237 words
An IC package carrier comprising: an IC package support plate having a square IC package accommodation section at the center thereof; an IC package press plate having at one end thereof a handle section for causing the IC package press plate to rise from and lie down on the upper surface of said IC package support plate, at the center thereof a square press section for pressing a square IC package, at the other end thereof a hinge mechanism constituted by couplings for coupling said IC package press plate to said IC package support plate and serving as hinges about which said IC package press plate is rotated, and two pairs of arms, one pair for connecting said handle section to said square press section and being superposed on one pair of adjacent corners of the IC package accommodated within said square IC package accommodation section of said IC package support plate and the other pair for connecting said square press section to said hinge mechanism and being superposed on the other pair of adjacent corners of the IC package; and closure retaining means provided on said handle section of said IC package press plate and a portion of said IC package support plate corresponding to the position of said handle section for detachably retaining said IC package press plate in a state of having lain down on the upper surface of said IC package support plate.

An IC package carrier comprising: an IC package support plate having a square IC package accommodation section at the center thereof; an IC package press plate having at one end thereof a handle section for causing the IC package press plate to rise from and lie down on the upper surface of said IC package support plate, at the center thereof a square press section for pressing a square IC package, at the other end thereof a hinge mechanism constituted by couplings for coupling said IC package press plate to said IC package support plate and serving as hinges about which said IC package press plate is rotated, and two pairs of arms, one pair for connecting said handle section to said square press section and being superposed on one pair of adjacent corners of the IC package accommodated within said square IC package accommodation section of said IC package support plate and the other pair for connecting said square press section to said hinge mechanism and being superposed on the other pair of adjacent corners of the IC package; and closure retaining means provided on said handle section of said IC package press plate and a portion of said IC package support plate corresponding to the position of said handle section for detachably retaining said IC package press plate in a state of having lain down on the upper surface of said IC package support plate.
Claim 3
Dependent Claim
50 words
An IC package carrier according to claim 1, wherein said IC package support plate has accommodating grooves formed in the upper surface thereof so as to communicate with the corners of said IC package accommodation section and accommodate therein said two pairs of arms of said IC package press plate.
Claim 4
Dependent Claim
66 words
An IC package carrier according to claim 1, wherein said square press section of said IC package press plate has its portions in the vicinity of the corners thereof pressed against the IC package and has its center apart from the upper surface of the IC package when said IC package press plate has lain down on the upper surface of said IC package support plate.
Claim 5
Dependent Claim
158 words
An IC package carrier according to claim 1, wherein said hinge mechanism comprises a pair of couplings provided on one end of said IC package press plate and provided each with a cut groove for affording resiliency to said couplings and with a pair of projections disposed on the opposite outer sides thereof across said cut groove, and engaging grooves formed in said IC package support plate for resiliently admitting said projections to rotatably and detachably attach said IC package press plate to said IC package support plate; and said closure retaining means comprises protuberances provided on the opposite outer side surfaces of said handle section, oblong holes formed in portions of said handle section in the vicinity of the opposite outer side surfaces thereof to afford resiliency to the opposite outer side surfaces, and stopping grooves formed in said IC package support plate in position corresponding to the positions of said protuberances for resiliently admitting said protuberances.
