<p>PURPOSE:To prevent erroneous recording by enabling a recording operation member, which reciprocates linearly, to rotate and by locking it to an interlocking connecting rod by a power drive system which uses the power of a motor for the reciprocation of a head substrate. CONSTITUTION:When playback operation is performed in a stop state shown in the figure, a head substrate operating rod 27 moves down in the figure and a lever 28 and a body 13 of revolution are disengaged from each other. A gear 3 and a gear part 7 engage with each other to rotate the body 13 of revolution clockwise, and a lever 19 rotates to slide a head substrate 18 as shown by an arrow A to a playback operation position, sliding a connecting rod 62 as shown by an arrow B. Even if a recording operation button 67 is operated in error in this state, an engagement part 63 and the connecting rod 73 comes into contact with each other, disabling recording operation. When the recording operation is performed in a stop state, a rod 73 slides as shown by an arrow C, and the substrate operating rod 27 also slides as shown by the arrow C. Then, the connecting rod 62 moves as shown by the arrow B, and the recording operation rod 73 rotates as shown by an arrow D to change a recording/reproduction changeover switch 69 from a reproduction side over to a recording state.</p> |
