ABSTRACT:
A cassette type tape recorder comprises a head base movably supported on a cassette type tape recorder structure and having magnetic heads and a pinch roller provided thereon. The head base is caused to move to a position apart from the position at which a tape cassette is to be loaded by the cassette eject operation, means responsive to loading of the cassette for moving the head base toward the cassette after it has been loaded to cause the magnetic heads to make contact with a magnetic tape within the cassette, and a mechanism for holding a pinch roller and a drive roller at positions apart from a capstan and a take-up reel disc respectively, even when the head base is moved. The manual operation of switching the tape recorder to the record or play mode after the cassette has been loaded causes only the holding mechanism to move, thus pressing the pinch roller and the drive roller against the capstan and the take-up reel disc respectively. In this operation it is not necessary to move the head base so that the mode of operation of the tape recorder can be manually changed by the application of a light force.
