CONSTITUTION:At the time of stopping mode, a motor and two pieces of plungers are turned off and keep plates 13 for both quick forwarding and rewinding are under a free condition. Also, a head plate 1 is retreated to the upper stopping position through a link 3. Switching between the playing mode and quick forwarding and rewinding modes is performed by connecting a quick forwarding or rewinding control plate 17 to the keep plate 13 for engaging a head lock plate 6 with a driving means.
