摘要： A rotary head device having a rotary drum and a rotating motor within the rotary drum, with the stator of the motor being supported by a fixed arm attached to a fixed drum or to a fixed drum supporting member. The construction permits the manufacture of the rotary head device using the manufacturing equipment used for conventional rotary shaft type rotary head devices despite the rotary head device being a thin device. In this rotary head device the position of contact of a ground brush and a rotor can be set at the center of rotation or thereabouts, so despite it being a thin device, the sliding speed of the ground brush is low, and hence it is possible to prevent the abrasion of the ground brush and also to prevent increase of the rotative driving torque.

摘要： A slide type cassette loading apparatus includes a loading section for receiving a tape cassette to move the same between an inlet/outlet position and a reference position for loading, and a movable chassis for sliding the cassette, located in the reference position, to a recording/reproducing position while carrying the cassette on the movable chassis. The loading section is of a double structure type which has an outer cassette holder pivotable relative to the movable chassis and an inner cassette holder supported to the outer cassette holder. The inner cassette holder is mounted on the outer cassette holder so as to make a pivotal movement together with the outer cassette holder and be movable in slide directions of the cassette, and is operatively coupled to the movable chassis so as to be movable together with the movable chassis.

摘要： A magnetic recording/reproducing apparatus has a chassis, a rotary cylinder mounted on the chassis, and at least one guide base movably disposed around the rotary cylinder. The guide base is provided with a guide member for drawing out a magnetic tape from a tape cassette. The guide member draws out the magnetic tape from the tape cassette, as the guide base is being moved, and winds the magnetic tape around the rotary cylinder so that a predetermined tape passage is defined. The magnetic recording/reproducing apparatus further has a capstan mechanism for driving the magnetic tape to run the same. The capstan mechanism is arranged on the same side of the chassis on which the rotary cylinder is disposed, and has a capstan downwards extending toward the chassis to come into direct contact with the magnetic tape.

摘要： In a rotary head drum of a recording/reproduction apparatus, for smoothly holding a magnetic tape over a guide step provided on a lower drum to guide the magnetic tape, part of a chamfer formed in the guide step is formed as a large chamfer in which a chamfered amount is larger than that of the remaining part of the chamfer. With the provision of the large chamfer, even if the lower edge of the magnetic tape deviates from the guide step when the tape is wound over or unwound from the drum, damages of the magnetic tape can be prevented. Therefore, the position and attitude control of tape withdrawing members can be greatly simplified and the magnetic tape can always run stably while being restricted in its position by the guide step. In the process of machining a tape running surface on the drum, by increasing the feed distance of a blade in the part of the chamfer where the large chamfer is to be formed by chamfering the guide step with a large chamfered amount, in comparison with the feed distance set in the remaining part of the chamfer, the large chamfer and the small chamfer can be both machined at the same time, resulting in simplified machining steps.

摘要翻译： 在记录/再现装置的旋转磁头鼓中，为了平滑地将磁带保持在设置在下磁鼓上的引导台上以引导磁带，形成在引导步骤中的倒角的一部分形成为大倒角，其中 倒角量大于倒角剩余部分的倒角量。 通过设置大倒角，即使当磁带从磁鼓卷绕或退绕时磁带的下边缘偏离引导步骤，也可以防止磁带的损坏。 因此，能够极大地简化卷取装置的位置和姿势控制，并且通过引导步骤限制在其位置，磁带总是可以稳定地运行。 在加工滚筒上的带子运行表面的过程中，通过在倒角部分中增加叶片的进给距离，通过以较大的倒角量倒角引导台阶，形成大倒角的部分，与 在倒角的剩余部分设置的进给距离，大倒角和小倒角可以同时加工，从而简化了加工步骤。

摘要： A plurality of tape guides are moved to wind a magnetic tape on a rotatable cylinder when the magnetic tape is to be loaded. An auxiliary guide mounted on a chassis of a magnetic recording and/or reproducing apparatus in position is made to touch the magnetic tape during a period for which the magnetic tape is being loaded, but it does not touch the magnetic tape when the magnetic tape has been loaded. The auxiliary guide can be protruded toward the magnetic tape from between the tape guides moving to touch the magnetic tape during the period for which the magnetic tape is being loaded so that the magnetic tape can be kept to a predetermined span.
