<p>PURPOSE:To easily set up the positioning accuracy of a tape guide and to reduce a load upon a loading ring by detaching a contact of an abutting part with a cam surface just before the completion of loading and turning a guide arm part by a spring toward a tape side. CONSTITUTION:The loading ring 19 is allowed to contact with the abutting part 45 until the last moment of completion of loading, and then the contact is detached by a circular cam 44 at the last moment of the completion. The spring 46 acts on the abutting part 45 of the guide arm part 16 to be brought into contact with the cam surface 44, and when th4e contact is detached, the arm part 16 is turned by the spring toward the tape T side. One end of the spring 46 is detained to the arm part 16, and the other end to a chassis respectively so that the rotating force is given anticlockwise to the arm part, thus preventing the tape guide 13 separating from the tape at the time of recording and reproducing. By this method, the accuracy of loading position is improved, while the load imposed on the loading ring from the tape guide side can alleviated due to receiving the spring tension by the cam surface 44.</p> |
