Abstract
An apparatus for locking a tape recorder door where even when a cassette is not loaded in the recorder, foreign objects are prevented from being inserted through the tape recorder door which is blocked by a locking pin of a locking lever, so that a breakdown or an accident due to the insertion of a foreign object can be avoided. However, when the cassette is inserted, an opening pin of an opening lever is pushed by the edge of the cassette to thereby raise the locking lever which is engaged with the opening lever, thus opening the door.
Claims5
An apparatus for locking a tape recorder door, comprising:
- a door through which a cassette is inserted and ejected, said door including a guide slot formed on at least one side thereof and an opening which communicates with said guide slot;
- an opening lever located on the at least one side of said door and operative to be pushed by an edge of the cassette during insertion of the cassette, said opening lever rotating to open said door when said cassette is ejected;
- and
- a locking lever, engaged with said opening lever, for releasing said door from a locked state when said opening lever moves, and blocking said door from opening when said opening lever does not move,
- wherein said opening lever comprises an opening pin slidably positioned in said guide slot, such that when foreign objects are attempted to be inserted through the door, said opening pin freely exists through said opening formed on said door and said opening lever does not move with said door, so that said locking lever blocks said door from opening, whereas when the cassette is properly inserted, said door opens by said opening pin being pushed by the edge of the cassette being inserted thereagainst and said opening lever rotates so as to raise said locking lever which is engaged with said opening lever, and when the cassette is ejected, rotation of said opening lever allows said opening pin to slide along said guide slot and said opening lever raises said locking lever to open the door.
