prevents a neutral position in which neither contact of
the switch is closed to ya terminal 65 at which a control
pulse, which may be from a separate source, but which
is preferably from the pulse generator 31, is applied.
The switch 64 may be manually ‘operated or may be
operated via the keyboard 34 and in one position causes
the moving control 29 to move the tape 15 in its for

moving control to move said tape in its backward direc

in the backward direction 19 during the course of opera
tion of moving control 29 by the described circuit ar
rangement, he will move the armature of the direction
switch 64 to contact the first contact 66a of said direction
switch and thereby cause the application of the control

operation on the tape 15, he positions the armature of
the switch 68 to contact the second contact 69b thereof
thereby supplying ythe control pulse to the Set input 67e
of the flip flop 67. This places the flip ilop 67 in its Set
condition so that no output signal is provided at the
Reset output 67a. The failure of application of a signal
at the Reset output 67a of the flip ilop 67 places the
AND gate 39 in its non-conductive condition thereby
blocking the control pulse from the pulse generator 31
and preventing it from passing to the perforator control
12 thus cutting off the perforation operation.
It is thus clear that during normal circuit operation
the switch 68 is closed on its iirst contact 69a and the
switch 64 is closed on its second contact 66h; the switch
