After that, a power source 24 is operated, a motion conversion means 16 moves, a reel base unit 14 moves up, the teeth section of the cassette tape 1 and the reel shaft 30 are engaged, a magnetic head supporting unit 8 moves a head 4 till the magnetic tape becomes a prescribed winding angle and a positioning is performed. On the other hand, during an unloading, by giving an unloading signal, the power source 24 is operated, the means 16 moves, the unit 8 goes backwards to the position till no interference exists between the head 4 and the tape 1 and the unit 14 lowers its position until the shaft 30 do not interfer with the cassette tape 1.</p> |
