ABSTRACT:
A cassette tape player comprises a reproduction head mounted on a subchassis, and a nonprogram section detection circuit for searching a nonprogram section provided between two adjacent programs recorded on a magnetic tape while the magnetic tape is driven to travel at a fast speed. When a fast forward lever or a fast rewind lever is locked under the condition where a playback lever is locked and the subchassis is held at a predetermined position, a switch mounted on the subchassis is switched on to power supply the nonprogram section detection circuit. That is, the cassette tape player is placed in a nonprogram section detection mode when both the playback lever, and the fast forward lever or the fast rewind lever are locked. Upon detecting the nonprogram section, a plunger is activated to unlock the fast forward lever or the fast rewind lever to return the cassette tape player to a normal playback mode.
