The present invention provides a carrier tape for storage use of super-miniaturized electronic components, by which the reflection of irradiated light which might cause detection errors cab be prevented, the product inspection can be performed easily and quickly, and number of stored pieces and remaining un-used pieces can be easily and quickly counted, when the presence or absence of deformation－which might take place on the lead portion of the electronic components being stored in the carrier tape－is examined by the optical equipment on the lead portion kept on the carrier tape. The surface of said base component can be treated to form a film to prevent the light reflection or to absorb the light, such as by painting with resins or ink which doesn\t reflect the light, or by immersion. Alternatively, the color of the base component is selected to be black. Moreover, by providing holes for the piece-counting on the carrier tape at a certain intervals, the number of components in the storage area can be counted by the photo-electric tube through said holes.

The improved carrier tape inspection system for increasing speed and accuracy in inspecting a longitudinally disposed carrier tape web carrying and storing a plurality of miniaturized electronic components along its length in spaced stations adapted to inspection of deformations in lead wires extending from the electronic components stored on the carrier tape by an external photoelectric inspection system photographically viewing the electric components on the carrier tape in response to illumination of the tape by an external light source which reflects light off the tape web in the vicinity of the lead wires, comprising in combination: a plurality of said electric components having said lead wires extending therefrom located at said spaced stations, said carrier tape comprising a longitudinal web of flexible material, said electronic components being affixed in place at said stations for inspection of said lead wires, means providing a photographic inspection directed normally toward one surface of the carrier tape at said spaced stations along the carrier tape for inspection of deformations of said lead wires on said electronic components by said photoelectric system, and light reflection reducing means disposed on said inspection side surface of the carrier tape web material to significantly reduce light reflection from the tape surface photographically interfering with images of the lead wires, whereby the inspection system more accurately and more quickly inspects the electronic components carried by the carrier tape with reduced interference from light reflected from the inspection side surface of the carrier tape.
