Abstract

A paper~outsensing apparatus 10 is shown for use in a printing machine of the type having a rotatable platen 12 for transporting a record material1 such as paper 14. The sensing apparatus 10 comprises a bail bar 16 of sub~ stantially coincident length with the platen. The bail bar is mounted to a pair of opposing brackets 18 for pivotal movement about a pair of pivot pins 20 respectively attached to the pair of brackets 18. The brackets themselves are mounted to the machine frame 26.

for transporting a record material

                        1 such as paper 14. The
sensing apparatus 10 comprises a bail bar 16 of sub~
stantially coincident length with the platen. The bail bar
is mounted to a pair of opposing brackets 18 for pivotal
movement about a pair of pivot pins 20 respectively attached
to the pair of brackets 18. The brackets themselves are
mounted to the machine frame 26.

The bail bar 16 has an extending finger 22 which is adapted
to engage the paper 14 when transported by the platen 12 or
the platen itself if no paper is transported

machine is out of paper. In this respect the bail bar 16 is biased by a spring (not shown) toward the platen. The
spring is relatively weak so that the slight bias force

imparted thereby is overcome by two inherent character~
istics of the paper being used, i.e., the weight of the
paper and the resistance of flexure set of the paper. Each
one or both simultaneously may overcome the bias of the
spring and force the bail bar 16 away from the platen 12.

The sensing apparatus 10 further comprises a switch 24 that
may be mounted...
