<p>PURPOSE:To prevent the damage of an interlocking member interlocked with a cam by moving the second moving means with the tension to a belt to set a rotation transmitting means to the non-transmission state, where this rotation transmitting means does not transmit the driving force of a capstan motor, when a cassette is not loaded. CONSTITUTION:The rotating force of a pulley 165 rotated clockwise together with a capstan 159 is transmitted to a pulley 166 through a belt 168; and through a turning arm 174 tries to turn counterclockwise around a supporting shaft 172 by engagement between gears 169 and 170 at this time, a pin 175 is brought into contact with a projecting piece 151 to generate friction between the turning arm 74 and a supporting shaft 171, and an idler gear 176 is rotated clockwise around a supporting shaft 177 but is not engaged with a gear 534 by this fric tion. In the mode other than cassette loading, the load generated by a cassette loading mechanism is not given to the first moving means, and members as the first moving means are not damaged and their life is extended.</p> |
