摘要： A magnetic recording/reproduction apparatus of the present invention, which records/reproduces information on/from a magnetic tape by passing the tape around a rotary head cylinder having a rotary head for a predetermined arc, includes: a capstan shaft; a pinch roller; a first reel base rotatably attached to a shaft; a second reel base rotatably attached to a shaft; and an idler supported swingably to swing to the second reel base when the capstan is rotated in a first direction and to the first reel base when the capstan shaft is rotated in a second direction, wherein the idler includes a gear portion which rotates in association with the rotation of the capstan shaft. The above components of the magnetic recording/reproduction apparatus are situated in such a manner that when the running of a magnetic tape is to be shifted from a first direction to a second direction, the rotation of the capstan shaft, in the first direction stops, the pinch roller moves away from the capstan shaft, the capstan shaft is rotated in the second direction by a predetermined amount so that the idler swings to the first reel base, the capstan shaft stops again, the pinch roller presses the magnetic tape against the capstan shaft, and the capstan shaft is rotated again in the second direction and the gear portion to be coupled with the first reel base, the gear portion rotating the first reel base in a direction in which the magnetic tape is wound onto the first reel.

摘要： A reel stand includes (a) a reel base for engaging a reel and driving the reel, (b) a bearing disposed in the reel base and being extended through by a rotary shaft, and (c) a spring being urged to the rotary shaft. This construction allows the reel stand to integrate a brake torque mechanism into its downsized body, and to provide a tape with uniform tape tension when the tape is taken up or supplied. The spring is pressed to the shaft to produce brake torque, which lowers the peripheral velocity of the shaft. As a result, less frictional heat is produced, which reduces changes in friction factors due to the heat.
