6. Mechanism operation

This mechanism consists of a capstan motor, reel motor,
and solenoid, with the power assist method by means of the
capstan motor. in the operation, there are 3 conditions:
STOP, PLAY, and CUE/REV. When the position is trig-
gered by the solenoid, by means of intermittent rotation of
the gear front the flywheel, as shown in Fig. l, cyclic shift-
ing is done,

To go from STOP to PLAY, if the solenoid is pulled in
for 301113, after about lSOms there is a shift to the PLAY
condition. From this condition, if the solenoid is again
pulled in, in that interval the condition shifts to CUE/
REV. However, to suppress heat generation in the solenoid,
the supply voltage must be reduced. If the power to the
solenoid is cut off, the head lowers, and the conuition
goes to STOP. In order to have a cyclic operation as stated
above, and to know the existing condition, a play switch is
provided, and this switch is ON for PLAY and OFF for
STOP (CUE/REV) is indefinite. When power is turned
ON, the mechanism makes use of an initializer.
