PURPOSE:To increase the reliability of magnetic tape rack operation, to simplify the constitution of unit and to decrease the cost, by constituting the drive mechanism of the tape unloading guide means of the magnetic tape rack unit with the flexible rack, rack drive guide groove, and pinion. CONSTITUTION:The protrusions 4d, 4d' of the magnetic tape unloading guide means 4, 4' on the guide base 5 are inserted and connected to the hole guides 37, 44 of the flexible racks 33 and 40. The motor 60 drives the pinion 46 via the worm 55 and the worm gear 47. The flexible racks 33 and 40 move toward the magnetic tape loading direction while sliding the external and internal side grooves of the guide groove outside 32 on the base 8, and introduce the unloading guide means 4,4' on the guide base 5 along the guide grooves 6, 6' in the same direction via the protrusions 4d, 4d'. The flexible racks 33, 40 are stopped when the guide means 4, 4' contact with the positioning member.
