ABSTRACT:
A magnetic recording-reproducing device operable by selective depression of various operating buttons and a manual switch in various modes. A reproduce button and a rewind button or a fast-forward button may be simultaneously locked in operative positions. A review mode is attained by the depression of the fast-forward button when the reproduce button is kept locked in the operative position. A cue mode is attained by the depression of the fast-forward button when the reproduce button is kept locked in the operative position. When the tape transport motion is halted as the tape is completely rewound or taken up in the review or cue mode, the rewind or fast-forward button is released from the locked position and the recording-reproducing device is switched into the reproduce mode. When no further tape transport is permitted, that is, when the tape is completely taken up in the cue mode, the reproduce button is released from the locked position and the magnetic recording-reproducing device is automatically switched to the stop mode. However, when the tape is completely rewound in the review mode, the recording-reproducing device remains in the reproduce mode and the tape is played back. When a tape counter displays a predetermined number, the locked rewind or fast-forward button may be automatically released and the recording-reproducing device may be automatically switched to the reproduce mode; and when a manual switch is kept open, the tape-transport motor is automatically stopped but the record and reproduce buttons are kept locked when the tape is completely taken up in the record mode.
