ABSTRACT:
A signal detection operating lever device comprises a first base plate, a second base plate parallel to the first base plate, a first operating lever between the base plates movable between a first position in which signal generator stops generating signal to stop running of a recording tape and a second position in which the signal generator generates the signal to determine a recording tape transport mode in the tape recorder, a second operating lever having a magnetic head and disposed between the base plates to move the magnetic head between a first position in which the head is separated from a tape and a second position in which the head comes in contact with the tape, an accidental erasure preventive lever movable between a first position in which the second operating lever is prohibited to move from the first position to the second position thereof, and a second position in which the second operating lever is allowed to move from the first position to the second position thereof, a third operating lever between the base plates movable between a first position which allows movement of the accidental erasure preventive lever between the first and second positions thereof, and a second position in which the accidental erasure preventing lever is kept at the second position thereof, a function selecting switch connected to the second and third operating levers for allowing the head to function as an erase head upon movement of the second operating lever to the second position thereof and for allowing the head to function as a signal detecting head upon movement of the third operating lever to the second position thereof.
