Device for manipulating a shutter

An improved device for manipulating a shutter adapted to cover an opening through which a tape cassette or disc cassette is inserted in an electronic device or removed therefrom, which includes a chassis containing a tape or disc cassette deck, a front panel detachably secured to the front face of the chassis, a shutter disposed at an opening which is formed at the front panel in order to put in or take out a tape or disc cassette from the cassette deck, the shutter being hinged to the inner side of the front panel so as to releaseably cover the opening, and means for manipulating the shutter to the released condition under which the tape or disc cassette from the cassette deck can be taken out through the opening, wherein the improvement comprising manipulating means in the form of a biased swinging lever having a base end pivotally supported at a side of the chassis and having a free end with a guide pin engageable with an extension or stump formed at one side of the shutter, and said stump having a deflector with a guide surface disposed at the rear side thereof;

• said swinging lever being flexible so as to cause the guide pin to be directed sideways away from the stump by the guide surface provided on the deflector;
• and said deflector being in the form of a triangular block attached to the rear surface of the stump with its guide surface inclining in a vertical direction in a manner to extend to side by side with the shutter, and with the swinging lever being formed of a flexible material with its width being sized thin so as to be directed to the side thereof.
