Abstract:
A magnetic tape unit comprising:a take-up reel for winding a magnetic tape thereon; a threader pin from which a leader block connected to a front end of the magnetic tape housed in a cartridge is suspended; a threader arm to which the threader pin is attached in order to lead the leader block from a tape exit of the cartridge up to an inside of the take-up reel by leading the threader pin from the tape exit of the cartridge up to the rotation center of the take-up reel; a motor for driving said threader arm; and an elastic body for restricting the backlash of the position of the threader arm by applying a torque which is opposed to a reactive torque of said motor to said threader arm so that the threader pin present at the rotation center of the take-up reel does not shift from the rotation center.
