A tape cartridge positioning apparatus for an endless magnetic tape cartridge player comprising a reciprocating lever member having front and rear arms between which the tape cartridge, which is transversely insertable in a player housing, is interposed and slidably mounted on a deck in the player housing and normally held in a first position, a shifting device operated by use of rotational force of a rotary capstan for drivingly feeding the magnetic tape to shift the reciprocating lever member from the first position to a predetermined second position, a latching device for retaining the reciprocating lever member in the second position, a release device for allowing the latching device to release retention of the reciprocating lever member, and a tension spring for returning the disengaged reciprocating lever member to the first position, and wherein the reciprocating lever member is caused to be moved from the first position to the second position, and thus the cartridge is moved to and held in the playing position as the rear edge thereof is urged by the rear arm while the reciprocating lever member is allowed to be returned from the second position to the first position and thus the cartridge is moved from the play position to the nonplaying position as the front edge thereof is urged by the front arm.
