PURPOSE: To prevent a tape from being damaged due to the supply of power source by interrupting the rotation of all motors based on a storage content of the occurrence of abnormality.when the abnormality occurs in the running of the tape.

CONSTITUTION: When the abnormality in the tape running occurs, the abnormality of the tape running is detected by any rotational abnormality of a drum motor, a capstan motor, a T reel motor, an S reel motor and a threading motor, and the information concerned is supplied to a system CPU 5 through a servo CPU 8. By the system CPU 5, the servo CPU 8 is controlled, and all motors are stopped, and the occurrence of the abnormality and the distinction of the motor whose rotation is inhibited are stored in a nonvolatile memory 6, and the occurrence of the abnormality is displayed on a panel display device 7. Then, by the CPU 5, whether or not a tape cassette is taken out is judged, and when NO, the fact that no tape cassette is taken out is written in the memory 6, and all operation are inhibited.
