<p>PURPOSE:To reduce the solenoid capacity at lock, by mounting the spring to the hold piece locking the pinch roller and the magnetic head into playing condition. CONSTITUTION:The spring 20 is mounted on the absorbing part 181 turning by taking the shaft 19 as fulcrum and absorbed to the holding solenoid 17, and the holding piece 18 having the stopper 182 of the turning plate 15, and the assembly is pulled counterclockwise. Thus, the cassette is inserted along the cassette guide 27 and shifted to the capstan 22 and reel shaft 29 while pushing the solenoid detection piece 28, the head fitting plate 13 is shifted to the cassette via the plunger 5, drive piece 14, and turning plate 15 with the operation of the solenoid 4 to be set in playing condition, anc the solenoid 17 is operated to absorb the absorbing part 181, the turning plate is locked with the stopper 182. When the pinch roller and the magnetic head 12 are locked in playing condition, the holding piece 18 is activated with the spring 20 to enable to reduce the capacity of the solenoid 17.</p> |
