Abstract
A magnetic tape drive in an auto-reverse tape recorder has a pair of reel-base gears, a pair of capstans, a pair of pinch rollers, a drive mechanism, a switching mechanism, and an oscillating mechanism. The drive mechanism selectively drives one of the pair of reel bases and selectively meshes with a cam gear, and the pair of reel bases has a gear that rotatively drives the reel base gear that is meshed with the cam gear. The switching mechanism switches a running direction of the magnetic tape from a first direction to a second direction, and the switching mechanism is reciprocated when the end of the magnetic tape is reached so that a first pinch roller that is abutting a first capstan moves away from the first capstan and a second pinch roller moves into contact with the second capstan. The switching mechanism has a switching lever that is reciprocated by the oscillating mechanism that includes a first oscillating mechanism that engages a cam portion of the cam gear and that is oscillated by a rotation of the cam gear and a second oscillating mechanism that is oscillated by the first oscillating mechanism so that the switching lever is reciprocated to change the running direction.
