It is an object of the invention to provide a
tape punching or perforating device which will
be simple in construction but reliable in operation.
It is a further object of the invention to prol0 vide improved mechanism for accurately advancing a message tape so that the same may be
perforated,
It is a further object of the invention to proVide a tape punching machine in which sucoesl5 sive unit perforations in a tape may be combined
in such a manner as to provide an improved
multiple unit perforation,
