Abstract
In a tape player having a pack guide movable up and down with respect to a reel base, a pack stopper movable back and forth relative to the pack guide, a swing plate supported for rotation relative to the pack guide, an inversion spring connected between the pack stopper and the swing plate and an ejection lever connected to the swing lever, so as to complete loading and ejection of a cassette by means of the expansion force of the inversion spring, the ejection mechanism comprises an eject lock arm pivotably supported relative to the pack guide and having one end which extends across the movement path of the pack stopper, a lock plate connected to the other end of the eject lock arm to lock the pack guide at the lifted position, a spring biasing the lock plate in a direction to maintain the locking of the pack guide, and a check arrangement combined with the eject lock arm to engage the pack stopper when the pack stopper moves forwardly to convey the cassette to the ejecting position.
