Claims
- 1. An operating lever device for a magnetic recording tape transport apparatus which uses a tape cassette, comprising:
- a first base plate;
- a second base plate parallel to said first base plate with a distance therebetween;
- first operating lever means disposed between said first and second base plates to be movable along the first and second base plates between a first position and a second position;
- second operating lever means disposed between said first and second base plates to be movable along the first and second base plates between first and second positions and parallel to the moving direction of said first operating lever means;
- an auxiliary operating lever disposed between said first and second base plates to be movable along the first and second base plates among first, second, third and fourth positions and perpendicularly to a direction of movement of said first and second operating lever means, said auxiliary operating lever in the first position thereof being spaced apart from said first and second operating lever means located in the first positions thereof in the locus of movement of said first and second operating lever means from the first position to the second position thereof, said auxiliary operating lever in the second position thereof being engaged with said first operating lever means located at the second position thereof, said auxiliary operating lever in the third position thereof being released from said first operating lever means located in the second position thereof by being spaced apart from the first position farther than from the second position in a direction from the first position to the second position thereof upon movement of said first operating lever means to the second position thereof and subsequent movement of said second operating lever means to the second position thereof, said auxiliary operating lever in the fourth position thereof being separated from the first position thereof in a dction from the second and third positions to the first position thereof upon movement of said first operating lever means to the first position thereof and subsequent movement of said second operating lever means to the second position thereof; and
- ejecting means disposed at least at one of said first and second base plates for ejecting the tape cassette from the magnetic recording tape transport apparatus upon movement of said auxiliary operating lever from the first position to the fourth position thereof.
- 2. The operating lever device of claim 1, wherein said recording tape transport apparatus includes a signal generating means for generating an electrical signal, and means for setting a magnetic recording tape transport mode in response to said electrical signal from said signal generating means.
- 3. The operating lever device of claim 2, wherein said first operating lever causes said signal generating means to stop generating said electrical signal when said first operating lever is at its first position; and wherein said signal generating means is permitted to generate said electrical signal when said first operating lever is at said second position thereof.
- 4. The operating lever device of claim 1, wherein said ejecting means comprises a drive member disposed between said first and said second base plates and having a face in confronting relation with a face of said auxiliary operating lever wherein said drive member is moved when the face of said auxiliary operating lever abuts the face of said drive member as said auxiliary operating lever moves towards its fourth position, said drive member including a projection, and an eject lever mounted on a front surface of said first base plate for pivotal movement perpendicular to said front surface, said eject lever including a projection having a slant face arranged to engage the projection of said drive member when said drive member is moved by said auxiliary operating lever wherein said eject lever is pivoted to eject the tape cassette.
- 5. The operating lever device of claim 1, wherein one of said base plates includes projections arranged to contact the periphery of said auxiliary operating lever for guiding the movement of said auxiliary operating lever through its operating positions.
- 6. The operating lever device of claim 4, including a single urging means disposed between said first and said second base plates for urging said auxiliary operating lever toward its first position and for urging said drive member of said ejecting means to a position at which the projection on said drive member is out of engagement with the slant face on the projection of said eject lever.
- 7. The operating lever device of claim 6, wherein said urging means is a leaf spring in the shape of a bent U.
- 8. The operating lever device of claim 7, wherein the leg portions of said leaf spring engage left and right side faces of an upwardly projected part of said auxillary operating lever, and the upper end of said leaf spring engages said drive member.
- 9. The operating lever device of claim 1, wherein said auxiliary operating lever includes a hook member, and said ejecting means comprises a rotating member pivoted between said first and said second base plates wherein a face of said rotating member abuts a face of said hook member so that said rotating member pivots along said first base plate when said auxiliary operating lever moves towards its fourth position, and an eject lever disposed on said first base plate for pivotal movement perpendicular to said first base plate, a part to said eject lever engaging a confronting part of said rotating member when said rotating member is pivoted by said hook member wherein said eject lever operates to eject the tape cassette.
- 10. The operating lever device of claim 9, including urging means disposed between said first and said second base plates for urging said auxiliary operating lever toward its first position intermediate the path of movement of said auxiliary operating lever through its remaining operating positions including the position at which said hook member rotates said rotating member by an amount sufficient to operate said eject lever.
