Claims
- 1. A signal detection operating lever device for a magnetic recording tape reproducing apparatus which uses a tape cassette and which sets a magnetic recording tape transport mode comprising:
- a first base plate;
- a second base plate parallel to said first base plate with a distance therebetween;
- a first operating lever 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 to determine a magnetic recording tape transport mode in the magnetic recording tape reproducing apparatus;
- a second operating lever having a magnetic head and disposed between said first and second base plates to move said magnetic head along said first and second base plates between a first position in which said magnetic head is separated from the magnetic recording tape of the tape cassette and a second position in which said magnetic head comes in contact with the magnetic recording tape;
- an accidental erasure preventive lever disposed at least at one of said first and second base plates to be movable between a first position in which said second operating lever is prohibited to move from the first position to the second position thereof, and a second position in which said second operating lever is allowed to move from the first position to the second position thereof;
- a third operating lever disposed between said first and second base plates to be movable between a first position which allows movement of said accidental erasure preventive lever between the first and second positions thereof along said first and second base plates, and a second position in which said accidental erasure preventing lever is kept at the second position thereof; and
- magnetic head function selecting means connected to said second and third operating levers for allowing said magnetic head to function as an erase head upon movement of said second operating lever to the second position thereof and for allowing said magnetic head to function as a signal detecting head upon movement of said third operating lever to the second position thereof.
- 2. The signal detection operating lever device of claim 1, wherein said magnetic recording tape transport mode is set in response to an electrical signal generated from a signal generating means.
- 3. The signal detection operating lever device of claim 2, wherein, when said first operating lever is disposed at said first position, said signal generating means stops generating said electrical signal; and wherein when said first operating lever is disposed at said second position, said signal generating means generates said electrical signal.
