<p>PURPOSE:To facilitate easy loading/unloading of a cassette, by holding forcibly a head support lever at its neutral position in response to the action to draw a mechanism structure out of a device main body and shifting the left side and right side magnetic heads to the inactive positions outside the cassette. CONSTITUTION:A mechanism structure 2 transmits the revolution via s belt 34 and by a motor 33 which is switched between its forward and backward revolutions by a flywheel 31 containing coaxially a capstan 32. A mobile frame 10 of the structure 2 slides forward on a fixed plate 11 of a device main body 1. When the structure 2 is drawn out of the main body 1. A holding pin 81 of a support lever 79 is held forcibly at its neutral position at a narrow slit 21a of a control hole 21. Accordingly a head support lever 71 is also held at its neutral position, and the magnetic heads 72 and 73 for forward and backward performance respectively are set at the inactive positions outside a cassette 35. Under such conditions, the cassette 35 can be easily loaded and unloaded.</p> |
