Claims (1)

[Scope of utility model registration request] A supply side loading means having a pole base equipped with a vertical pole and an inclined pole for pulling out a magnetic tape from a tape cassette mounted on the apparatus and guiding the magnetic tape on the entrance side and the exit side with respect to the tape guide drum, and a winding means. In the magnetic recording and/or reproducing apparatus, the magnetic tape is wound around the tape guide drum over a predetermined angle range, and the magnetic tape is wound on the tape guide drum over a predetermined angle range. A magnetic recording device characterized in that the upper part of each vertical pole provided in each side loading means is supported by a U-shaped recess formed in a stopper part, and the lower part is supported by a V-shaped recess. /or playback device.
