Claims

[Claims for Utility Model Registration] 1. A file reel supported within a specific plane for winding a magnetic tape, a machine reel supported adjacent to the file reel in the same plane as the file reel, and a machine reel for driving the file reel. Controls a file reel drive motor, a machine reel drive motor that drives a machine reel, a capstan that drives a magnetic tape in both directions between the file reel and the machine reel, a file reel drive motor, a machine reel drive motor, and the capstan. In the magnetic tape transport device, the tape path for guiding the tape between the file reel and the machine reel includes first and second negative pressure chambers disposed on the specific plane, and both negative pressure chambers are arranged on the specific plane. Each has a front plate, a rear plate, a bottom plate, and two parallel side plates, one negative pressure chamber is located close to the file reel, the other negative pressure chamber is located close to the machine reel, and the first negative pressure chamber is located close to the file reel. The parallel side plate is formed in a V shape with respect to the parallel side plate of the second negative pressure chamber, and both bottom plates are the apex portions of the V shape, and the first negative pressure chamber is placed close to and parallel to the tangent to the file reel. The tangent intersects the horizontal line passing through the center of the file reel at an angle in the range of 10° to 20°, and the second negative pressure chamber
, and the second tangent line is at an angle of 60° to the horizontal line of the file reel.
means for guiding the magnetic tape along said tape path at an angle in the range of 70°, said tape path further comprising first and second auxiliary negative pressure chambers; The auxiliary negative pressure chambers are located close to the first and second negative pressure chambers, and each of the auxiliary negative pressure chambers has a front plate, a rear plate, and two side plates, and one side plate is connected to the first and second negative pressure chambers. A tape conveying device characterized in that the side plate of the negative pressure chamber of No. 2 is common to the side plate of the negative pressure chamber. 2. Utility Model Registration The tape conveying device according to Claim 1, characterized in that the non-common side plates of the first negative pressure chambers are located close to the file reel.
