Abstract
An improved automatic reverse apparatus for a magnetic tape recorder/player of the type which employs a magnetic tape contained in a cassette provided with first and second channels. The apparatus further includes a magnetic head with head channels adapted to contact and selectively record or reproduce each of the tape channels. A pair of reels are provided for winding and rewinding the tape and a pair of capstans and pinch rollers are utilized for alternatively transferring the tape in the forward and reverse directions between the reels. The apparatus includes an operating lever which can be moved and set at two different positions to effect reversal of tape direction and switching between tape channels. A mechanical signal is generated when the tape has been fully wound upon one of the reels which in turn causes reciprocating movement of an actuator mechanism. The latter movement causes the operating lever to swing to either its first or second position. The operating lever is locked at each position by a locking mechanism until another reciprocating movement disables the locking mechanism and causes the lever to swing to the next position. The movement of the operating lever to…
