Abstract
Abstract In a tape player of the type wherein a cassette containing a pair of reels on which a sound tape is wound is removably loaded in a predetermined position of a base of the player, the tape is passed between a first pair of a pinch roll and a capstan and between a second pair of a pinch roll and a capstan and said first and second pairs are selectively operated to reverse the direction of running of the tape with respect to a sound reproducing head thereby enabling continuous reproduction of a plurality of channels recorded on the tape, there are provided switching means for selectively operating either one of the first and second pairs, and control means for urging the switching means always in a given direction thereby enabling loading of the cassette while the tape is driven in a given direction.

Claim 1
Independent Claim
200 words
In a tape player of the type having a sound reproducing head and wherein a cassette containing a pair of reels on which a sound tape is wound is removably loaded in a predetermined position in said player and said tape is passed between a first drive pair comprising pinch roller and a capstan and then between a second drive comprising a pinch roller and a capstan, and said first and second tape drive pairs are selectively operated to reverse the direction of running of said tape with respect to said sound reproducing head, thereby enabling continuous reproduction of a plurality of channels recorded on said tape, the improvement which comprises the combination of switching means for selectively operating either one of said first and second pairs; control means for constantly urging said switching means in a given direction thereby permitting loading of said cassette while said tape is driven in a given direction; and a movable plate which is moved in a vertical direction with respect to the reel hubs of said cassette loaded in said player, said control means being actuated in response said switching means when said player is prepared for loading and unloading of said cassette.
Claim 2
Dependent Claim
