inwards by the locking clip (
​
135 FIG 9
​
). The possibility would otherwise not be excluded that the
Deus/”RESTART”??
​
of the driver would be hit by the cam.
8. Putting the control disk into motion at the end to a disk
This is obtained as at startup by the drive device which is moved on the control disk
towards the main axis. However, this is not done under the influence of the
​
starting
spring
​
but in another way. As the pick-up arm is brought inwardly by the groove of the
disk, the drive device (120)
​
frictionally
​
mounted on the guide hook will come into
contact towards the end of the disk. with the drive device on the control disc, the
latter can rotate freely around its bearing, and the nose will slowly approach the
main axis However, as long as the needle is not engaged in the exit groove of the
disc, the nose should not be touched by a cam (D Fig. 8) of the axis, otherwise the
disc would stop too soon. The purpose of the
​
fiber disc
​
is to avoid that. As this disc
is constantly pushed back, at the end of the disc, by a cam of the axis, the nose will
not be touched. After the pickup has moved one more groove inwards, the small disk
receives a small clmoc of the cam on the axis, and the drive device of the guide hook
is pushed back slightly.
This continues until the needle reaches the exit groove and thus causes a large
acceleration
​
directed inwardly of the guide hook, as well as the integral drive device
(
​
120
​
). With this
​
rapid movement
​
, the driving device of the control disk is also
moved rapidly, and the nose then comes into contact with a cam, which puts the control
disk in motion. In fact, the
​
fiber disk
​
exists only because not all the disks have
their output
​
pillon
​ ​
final groves???
​
at the
​
same distance from the center
​
, and it is
intended to eliminate these differences. The
​
necrosis
​
of the
​
friction
​
is important for
that the mechanism engages in time, When the control disk has completed its rotation,
the drive device is pushed inward by the starter bracket (135). Otherwise it would not
be impossible to "restart" immediately.
9. Stop automatically after the last record has been played.
AFTER PASSING THE LAST DISC,The mechanism normally comes into play after the end DISC has
finished, thus giving the DISC/plate printer the opportunity to fall. As a result, the lower end of the guide
rod (
​
97
​
) comes into such a position that the steering hook is blocked and the P.U. arm falls on the
switch, so that it is opened, so that the MOTOR stops. The ROLLER on the CONTROL DISC SLIDES/shifts
inward.
10. REPEATING a DISC/record.
When the "
​
repeat" button
​
is pressed, the movement of the latch (
​
74
​
) is blocked so that no new plate
falls and the P.U. thus RESETS /returns to the same DISC/plate. The
​
repeat button
​
is automatically
pushed back by the SPINDLE/pen
(D fig.9
​
) on the CONTROL DISC and further by the horseshoe SPRING/feather (
​
78 FIG 8.)
​
. Certain
passages of the plate can be repeated by moving the P.U. arm by hand.
