<p>PURPOSE:To hold a cassette half surely, by pressing a slope face 1c of the cassette half, which is set to a cassette holder, in the direction of a magnetic head. CONSTITUTION:A regulating arm 15 is turned at the play time in accordance with the forward motion of a head base 6 and release the regulation of rocking of an arm 12. Then, the arm 12 is rocked by a spring 14 and presses the slope face 1c of a cassette half 1 with its tip. At this time, a horizontal resultant force Fa of a force F which acts upon the slope face 1c of the cassette half 1 is the force which holds the cassette half in the state a head 5 is pressed to a magnetic tape in the half 1. Meanwhile, the cassette half 1 is pressed downward by a flat spring 11 attached to a cassette holder 10, and this downward pressing force is made stronger than a vertical force component Fb to hold the cassette half 1 in a prescribed position without floating it.</p> |
