  "claims": [
    "1. A terminal electrode forming method for chip-style electronic components, comprising: an arraying step of arraying the chip-style electronic components on an arraying flat bed thereby positioning and aligning said chip-style electronic components; an adhering step of lowering a first film coated with an adhesive together with an adhering top plate parallel to said arraying flat bed in relative manner thereto, thereby adhering ends of the positioned and aligned chip-style electronic components to said adhesive; a coating step of lowering said first film, to which the chip-style electronic components are adhered, in relative manner and together with a coating top plate parallel to a coating flat bed provided with a conductive paste layer of a constant thickness thereby pressing the other ends of the chip-style electronic components to said coating flat bed; and a drying step of drying the conductive paste coated on said other ends in said coating step by mainly heating the conductive paste coated part of the chip-style electronic components.",
    "2. A terminal electrode forming method for chip-style electronic components according to claim 1, further comprising a reversing step of positioning a second film coated with an adhesive on a reversing flat bed, lowering in relative manner said first film holding the chip-style electronic components after said drying step, together with a reversing top plate thereby adhering the ends coated with the conductive paste of the chip-style electronic components to the adhesive of said second film, then peeling off said first film together with the adhesive thereof, and reversing said second film holding the chip-style electronic components.",
    "3. A terminal electrode forming method for chip-style electronic components according to claim 1, wherein said film is formed as a tape and is fed from a roll and is wound on another roll thereby conveying the chip-style electronic components held by said adhesive.",
    "4. A terminal electrode forming method for chip-style electronic components according to claim 1, wherein said drying step executes drying by concentrating far-infrared light to the portions coated with the conductive paste of the chip-style electronic components.",
    "5. A terminal electrode forming method for chip-style electronic components according to claim 2, wherein said adhesive is a thermal foaming-release adhesive, and the heating of said first film causes the first film and the adhesive thereof to be released from the chip-style electronic components held by the second film."

  "description_excerpt": "1. Field of the Invention\n\nThe present invention relates to a terminal electrode forming method for a chip-style electronic component and an apparatus therefor, and more particularly to a terminal electrode forming method for a chip-style electronic component and an apparatus therefor, capable of adapting to miniaturization of the chip-style electronic component, improving the quality of the terminal electrode and adaptable to mass production by executing conductive paste coating etc. while holding the chip-style electronic component by a film coated with an adhesive material.\n\n2. Related Background Art\n\nIn general, the terminal electrode formation in a chip-style electronic component means forming a connecting electrode at an end of the chip-style electronic component by coating, drying and sintering paste containing silver, silver-palladium, copper etc. on such end portion, for the purpose of connection with an internal conductor or an internal electrode of the chip-style electronic component. The present invention describes a method for forming a terminal electrode on both ends of a chip-style electronic component such as a ceramic capacitor or a noise filter.\n\nIn the conventional terminal electrode forming method for the chip-style electronic component, the chip-style electronic components are held, as shown in FIG. 11, by forming holding holes 51 in silicone rubber 60 and inserting the chip-style electronic components 1, aligned by an insertion guide plate 52, into the holes 51 with inserting pins 53. Such holding method for the chip-style electronic components is however associated with the following drawbacks.",
