PURPOSE:To make small the tape container and the unit, by determining the attitude of the tape drawing member, when the movement of the tape drawing member is made on the guide plate providing the guide groove. CONSTITUTION:The magnetic tape 3 is drawn out from the tape container 2, and the tape drawing members 19a, 19b in contact with the tape guide drum 16 are moved along the guide grooves 24a, 24b provided with the guide plate 23. When this tape drawing members 19a, 19b are located on the openings 5, 6 provided with the tape container 2, the virtual planes 29a, 29b of the tape drawing members 19a, 19b are almost parallel with the magnetic tape. This is because the center of curvature of the guide groove 24a is taken as the two parts 25, 26 and the shape of the guide groove 24a is selected by putting them on the both sides of the guide groove 24. With this constitution, the tape container 2 and the unit can be made small. |
