Abstract
Abstract A cover tape for sealing chips in chip-holding parts of a carrier tape having said parts provided discontinuously and longitudinally of said carrier tape, which cover tape comprises a base tape, an adhesive layer formed on one surface of said base tape and a non-adhesive coat formed on said adhesive layer along the longitudinal direction of said base tape so that said non-adhesive coat has a width broader than that of the chips and narrower than that of said adhesive layer. When the cover tape is used in combination with the carrier tape, the chip-holding parts are sealed by the cover tape having the non-adhesive coat and in consequence the chips held in the chip-holding parts do not come in contact with the adhesive layer although they might come in contact with the non-adhesive coat. Accordingly, the chips are not stained by the adhesive in the adhesive layer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
A device for packing chips comprising: a carrier tape having chip-holding parts provided intermittently and longitudinally of said carrier tape; and a cover tape on said carrier tape for sealing chips in said chip-holding parts, said cover tape including: a base tape, an adhesive layer formed on only one surface of the base tape, and a non-adhesive layer containing an oxidation-cured ink and pattern-printed on the adhesive layer centrally along the longitudinal direction of the base tape so that the non-adhesive layer has a width greater than that of the chips and covering said chip-holding parts, and less than that of the adhesive layer with the parts of said adhesive layer which are free of said non-adhesive layer adhered to said carrier tape.
Claim 2
Independent Claim
123 words
A device for packing chips comprising: a carrier tape having chip-holding parts provided intermittently and longitudinally of said carrier tape; and a cover tape on said carrier tape for sealing chips in said chip-holding parts, said cover tape including: a base tape, an adhesive layer formed on only one surface of the base tape, and a non-adhesive layer containing an oxidation-cured ink and pattern-printed on the adhesive layer centrally along the longitudinal direction of the base tape so that the non-adhesive layer has a width greater than that of the chips and covering said chip-holding parts, and less than that of the adhesive layer with the parts of said adhesive layer which are free of said non-adhesive layer adhered to said carrier tape.
Claim 3
Independent Claim
125 words
A device for packing chips comprising a carrier tape having chip-holding parts provided intermittently and longitudinally of said carrier tape; and a cover tape on said carrier tape for sealing chips in said chip-holding parts, said cover tape including: a base tape, an adhesive layer formed on only one surface of the base tape, and a non-adhesive layer containing an antistatic agent and pattern-printed on the adhesive layer centrally along the longitudinal direction of the base tape so that the non-adhesive layer has a width greater than that of the chips and covering said chips and holding parts, and less than that of the adhesive layer with the parts of said adhesive layer which are free of said non-adhesive layer adhered to said carrier tape.
Claim 4
Independent Claim
125 words
A device for packing chips comprising a carrier tape having chip-holding parts provided intermittently and longitudinally of said carrier tape; and a cover tape on said carrier tape for sealing chips in said chip-holding parts, said cover tape including: a base tape, an adhesive layer formed on only one surface of the base tape, and a non-adhesive layer containing an antistatic agent and pattern-printed on the adhesive layer centrally along the longitudinal direction of the base tape so that the non-adhesive layer has a width greater than that of the chips and covering said chips and holding parts, and less than that of the adhesive layer with the parts of said adhesive layer which are free of said non-adhesive layer adhered to said carrier tape.
Claim 5
Independent Claim
123 words
A device for packing chips comprising: a carrier tape having chip-holding parts provided intermittently and longitudinally of said carrier tape; and a cover tape on said carrier tape for sealing chips in said chip-holding parts, said cover tape including: a base tape, an adhesive layer formed on only one surface of the base tape, and a non-adhesive layer containing a radiation-cured ink and pattern-printed on the adhesive layer centrally along the longitudinal direction of the base tape so that the non-adhesive layer has a width greater than that of the chips and covering said chip-holding parts, and less than that of the adhesive layer with the parts of said adhesive layer which are free of said non-adhesive layer adhered to said carrier tape.
