トデツキ。In a cassette deck equipped with a running means for running a magnetic tape, a magnetic head for reading information recorded on the magnetic tape, and a speaker for outputting an output signal of the magnetic head, a signal is emitted from the magnetic head. a detecting means for detecting whether or not the information is being output; and a detecting means for detecting whether an unrecorded portion of information on the magnetic tape has passed over the magnetic head continuously for a certain period of time or more based on the detection result of the detecting means. a determining means for determining whether a silent portion of the magnetic tape has passed over the magnetic head continuously for a predetermined period of time or more when the magnetic tape is running at a reproduction speed; When the magnetic tape is wound in fast forward, the traveling means is controlled to wind the magnetic tape in fast forward, and when the magnetic tape is wound in fast forward, the detecting means moves the magnetic tape over the magnetic head. 1. A cassette deck comprising: control means for controlling said running means to run said magnetic tape at a playback speed when it is detected that a silent portion of said magnetic tape has not passed.
