<p>PURPOSE:To improve the operativity of the operating device, by providing a gear holding member which holds a driven gear and allows a driving gear and the driven gear to contact and leave each other, and a displacing member which displaces the gear holding member all the time in such a direction that the driving gear engages the driven gear. CONSTITUTION:The operating device is equipped with the gear holding member 3 which holds the driven gear 2 and allows the driving gear 1 and driven gear 2 to contact and leave each other, and the elastic displacing member 12 which displaces the gear holding member 3 all the time in such a direction that the driving gear and driven gear 2 engage each other. A conventional operating device is not capable of ejecting a cassette in case of a voltage drop, but this device of said simple constitution ejects the tap cassette easily without damaging the mechanism to improve the operativity remarkably.</p> |
