Abstract: A connection tape (20) for connecting ends of square hole-punched carrier tapes (1) each of which comprises a carrier tape (11) formed with sprocket holes (11a) and pocket holes (11b), a top cover tape (12) and a bottom cover tape (13) attached on its top and bottom surfaces, respectively. The connection tape has a three-layer structure comprising a base tape (30), an adhesive tape (40) and a protection tape (50). The adhesive tape is composed of a first adhesive tape (41) which can adhere to the top cover tape, a second adhesive tape (42) which can adhere over the top of the sprocket holes in the carrier tape without interfering with the top cover tape, and a third adhesive tape (43) which can attach to the bottom cover tape. The second adhesive tape has sprocket holes (42a) which correspond to the sprocket holes in the square hole-punched carrier tape.

Abstract: The present invention is provided with an automatic manufacturing method of a switch sheet comprising a concave face switch and an apparatus thereof.A refuse removing tape 7 is stuck on a lower surface of a film separator 4 so that an adhesive layer thereof may fit it before a first punch device 14 forms first holes in the film separator 4. Then, a processing tape 5 is stuck on an upper surface of the film separator 4 so that an adhesive layer of the processing tape may fit it before a second punch device 15 punches the processing tape 5 in a setting shape at the same time while forming second holes through the processing tape 5, the film separator 4 and the refuse removing tape 7. After that, the punched processing tape is wound to be stripped when pulling out the film separator 4 and the refuse removing tape 7 on which the processing tape 5 in a setting shape is stuck.

Abstract: The present invention relates to a method for constructing a liquid crystal display, including a first step for connecting a first end part of a TAB film provided with a chip such as an LSI and an IC to an end part of a liquid crystal panel, and a second step for connecting a second end part of the TAB film to an end part of a printed board using solders, the end part of the printed board being formed to have projecting portions. According to the present method, prior to the second step, a tape is prepared, whose long side is cut to have projecting portions corresponding to the projecting portions of the end part of the printed board. Then, adhesive materials are thinly and evenly applied to a rear surface of each projecting portion of the tape. Thereafter, the tape is attached to the printed board so that the projecting portions of the tape may coincide with the projecting portions of the printed board and the adhesive materials may be applied to prescribed portions of the printed board.
