<p>PURPOSE:To automate a series of operations from the state of storage array at a fixed storage array position to a reproducing device by providing an automatic video reproduction system with a fixed carrying method for a tape. CONSTITUTION:Cartridge 1 consists of bobbin 5 that has as a main constituent element main bobbin body 4 with winding surface 3 for magnetic tape 2 and cylindrical case 6 in which bobbin 5 is stored and held. As for bobbin 5, the outer circumferential surface of cylindrical part 7 is used as winding surface 3 and bobbin body 4 having collar parts 8 and 9 formed in a body at both sides of cylinder part 7 is provided. Collars 8 and 9 are tapered from tape winding surface 3 to each tip, and when bobbin 5 is inserted into case 6 or equipped to the rotation driving part of a reproducing device, outer circumferential surfaces 15 and 16 perform guide operation. Further, magnetic substance part 17 is provided on the top surface of collar 8, and opening 19 and hook part 20 for rotation drive are provided on that of collar 9.</p> |
