    摘要: A magnetic recording and reproduction apparatus includes an arm section pivotable about a pivoting shaft; a tape guide section provided on the arm section for guiding a magnetic tape; a capstan section for driving the magnetic tape so as to run; and a maintaining section provided on the capstan section. The arm section is pivotable between a first location and a second location. The first location is a location at which the information recording to and/or information reproduction from the magnetic tape is possible. The second location is a location at which the information recording to and/or information reproduction from the magnetic tape is not possible. When the arm section pivots from the second location to the first location, the maintaining section maintains a relative position of the arm section, which is in the first location, to the capstan section.

    摘要: According to the present invention, a hollowed portion is formed on a lower bonded surface of a rotary drum to which a rotation-side rotary transformer is bonded, and a hollowed portion is formed on an upper bonded surface of the fixed drum to which a fixation-side rotary transformer is bonded. Thus, excessive adhesive is absorbed by the hollowed portions and adhesive layers do not have uneven thicknesses, thereby securing surface runout accuracies of the rotary transformers. Further, since an adhesive is applied to the outer peripheral side of the hollowed portion of the rotary drum, the adhesive does not flow into ball bearings located on the inner peripheral side.

    摘要: A small-sized and low-power magnetic tape recording and/or reproducing apparatus. A first idler is press-contacted with a driving roller provided coaxially with a capstan shaft for transporting a magnetic tape at a constant speed, the pressing force of the first idler being changed so as to obtain a driving force caused by friction according to the pressing force. The driving force of the first idler is transmitted to a relay wheel via a timing belt mounted on the first idler and the relay wheel, and to a reel drive turntable by a reel transmission mechanism. The reel transmission mechanism has a selective transmission mechanism which transmits the rotation of the relay wheel to a rotating wheel juxtaposed with the reel drive turntable and then to the reel drive turntable either directly or indirectly via a torque limiter provided on the rotating wheel.
